+	 * 2. Closing a primary and an off-page duplicate cursor stack: we
+	 *    get called with a pointer to the primary cursor which has a
+	 *    non-NULL opd field.  This happens when closing a btree cursor
+	 *    into database with an associated off-page btree/recno duplicate
+	 *    tree. (It can't be a primary recno database, recno databases
+	 *    don't support duplicates.)
+	 *
+	 * 3. Closing an off-page duplicate cursor stack: we get called with
+	 *    a pointer to the off-page duplicate cursor.  This happens when
+	 *    closing a non-btree database that has an associated off-page
+	 *    btree/recno duplicate tree or for a btree database when the
+	 *    opd tree is not empty (root_pgno == PGNO_INVALID).
+	 *
+	 * If either the primary or off-page duplicate cursor deleted a btree
+	 * key/data pair, check to see if the item is still referenced by a
+	 * different cursor.  If it is, confirm that cursor's delete flag is
+	 * set and leave it to that cursor to do the delete.
+	 *
+	 * NB: The test for == 0 below is correct.  Our caller already removed
+	 * our cursor argument from the active queue, we won't find it when we
+	 * search the queue in __bam_ca_delete().
+	 * NB: It can't be true that both the primary and off-page duplicate
+	 * cursors have deleted a btree key/data pair.  Either the primary
+	 * cursor may have deleted an item and there's no off-page duplicate
+	 * cursor, or there's an off-page duplicate cursor and it may have
+	 * deleted an item.
+	 *
+	 * Primary recno databases aren't an issue here.  Recno keys are either
+	 * deleted immediately or never deleted, and do not have to be handled
+	 * here.
+	 *
+	 * Off-page duplicate recno databases are an issue here, cases #2 and
+	 * #3 above can both be off-page recno databases.  The problem is the
+	 * same as the final problem for off-page duplicate btree databases.
+	 * If we no longer need the off-page duplicate tree, we want to remove
+	 * it.  For off-page duplicate btrees, we are done with the tree when
+	 * we delete the last item it contains, i.e., there can be no further
+	 * references to it when it's empty.  For off-page duplicate recnos,
+	 * we remove items from the tree as the application calls the remove
+	 * function, so we are done with the tree when we close the last cursor
+	 * that references it.
+	 *
+	 * We optionally take the root page number from our caller.  If the
+	 * primary database is a btree, we can get it ourselves because dbc
+	 * is the primary cursor.  If the primary database is not a btree,
+	 * the problem is that we may be dealing with a stack of pages.  The
+	 * cursor we're using to do the delete points at the bottom of that
+	 * stack and we need the top of the stack.

+
+The design of file operation recovery.
+
+Keith has asked me to write up notes on our current status of database
+create and delete and recovery, why it's so hard, and how we've violated
+all the cornerstone assumptions on which our recovery framework is based.
+
+I am including two documents at the end of this one.   The first is the
+initial design of the recoverability of file create and delete (there is
+no talk of subdatabases there, because we didn't think we'd have to do
+anything special there).  I will annotate this document on where things
+changed.
+
+The second is the design of recd007 which is supposed to test our ability
+to recover these operations regardless of where one crashes.  This test
+is fundamentally different from our other recovery tests in the following
+manner.  Normally, the application controls transaction boundaries.
+Therefore, we can perform an operation and then decide whether to commit
+or abort it.  In the normal recovery tests, we force the database into
+each of the four possible states from a recovery perspective:
+
+	database is pre-op, undo (do nothing)
+	database is pre-op, redo
+	database is post-op, undo
+	database is post-op, redo (do nothing)
+
+By copying databases at various points and initiating txn_commit and abort
+appropriately, we can make all these things happen.  Notice that the one
+case we don't handle is where page A is in one state (e.g., pre-op) and
+page B is in another state (e.g., post-op).  I will argue that these don't
+matter because each page is recovered independently.  If anyone can poke
+holes in this, I'm interested.
+
+The problem with create/delete recovery testing is that the transaction
+is begun and ended all inside the library.  Therefore, there is never any
+point (outside the library) where we can copy files and or initiate
+abort/commit.  In order to still put the recovery code through its paces,
+Sue designed an infrastructure that lets you tell the library where to
+make copies of things and where to suddenly inject errors so that the
+transaction gets aborted.  This level of detail allows us to push the
+create/delete recovery code through just about every recovery path
+possible (although I'm sure Mike will tell me I'm wrong when he starts to
+run code coverage tools).
+
+OK, so that's all preamble and a brief discussion of the documents I'm
+enclosing.
+
+Why was this so hard and painful and why is the code so Q@#$!% complicated?
+The following is a discussion/explanation, but to the best of my knowledge,
+the structure we have in place now works.  The key question we need to be
+asking is, "Does this need to have to be so complex or should we redesign
+portions to simplify it?"  At this point, there is no obvious way to simplify
+it in my book, but I may be having difficulty seeing this because my mind is
+too polluted at this point.
+
+Our overall strategy for recovery is that we do write-ahead logging,
+that is we log an operation and make sure it is on disk before any
+data corresponding to the data that log record describes is on disk.
+Typically we use log sequence numbers (LSNs) to mark the data so that
+during recovery, we can look at the data and determine if it is in a
+state before a particular log record or after a particular log record.
+
+In the good old days, opens were not transaction protected, so we could
+do regular old opens during recovery and if the file existed, we opened
+it and if it didn't (or appeared corrupt), we didn't and treated it like
+a missing file.  As will be discussed below in detail, our states are much
+more complicated and recovery can't make such simplistic assumptions.
+
+Also, since we are now dealing with file system operations, we have less
+control about when they actually happen and what the state of the system
+can be.  That is, we have to write create log records synchronously, because
+the create/open system call may force a newly created (0-length) file to
+disk.  This file has to now be identified as being in the "being-created"
+state.
+
+A. We used to make a number of assumptions during recovery:
+
+1. We could call db_open at any time and one of three things would happen:
+	a) the file would be opened cleanly
+	b) the file would not exist
+	c) we would encounter an error while opening the file
+
+Case a posed no difficulty.
+In Case b, we simply spit out a warning that a file was missing and then
+	ignored all subsequent operations to that file.
+In Case c, we reported a fatal error.
+
+2.  We can always generate a warning if a file is missing.
+
+3. We never encounter NULL file names in the log.
+
+B. We also made some assumptions in the main-line library:
+
+1. If you try to open a file and it exists but is 0-length, then
+someone else is trying to open it.
+
+2. You can write pages anywhere in a file and any non-existent pages
+are 0-filled. [This breaks on Windows.]
+
+3. If you have proper permissions then you can always evict pages from
+the buffer pool.
+
+4. During open, we can close the master database handle as soon as
+we're done with it since all the rest of the activity will take place
+on the subdatabase handle.
+
+In our brave new world, most of these assumptions are no longer valid.
+Let's address them one at a time.
+
+A.1 We could call db_open at any time and one of three things would happen:
+	a) the file would be opened cleanly
+	b) the file would not exist
+	c) we would encounter an error while opening the file
+There are now additional states.  Since we are trying to make file
+operations recoverable, you can now die in the middle of such an
+operation and we have to be able to pick up the pieces.  What this
+now means is that:
+
+	* a 0-length file can be an indication of a create in-progress
+	* you can have a meta-data page but no root page (of a btree)
+	* if a file doesn't exist, it could mean that it was just about
+		to be created and needs to be rolled forward.
+	* if you encounter an error in a file (e.g., the meta-data page
+		is all 0's) you could still be in mid-open.
+
+I have now made this all work, but it required significant changes to the
+db_open code and error handling and this is the sort of change that makes
+everyone nervous.
+
+A.2.  We can always generate a warning if a file is missing.
+
+Now that we have a delete file method in the API, we need to make sure
+that we do not generate warning messages for files that don't exist if
+we see that they were explicitly deleted.
+
+This means that we need to save state during recovery, determine which
+files were missing and were not being recreated and were not deleted and
+only complain about those.
+
+A.3. We never encounter NULL file names in the log.
+
+Now that we allow tranaction protection on memory-resident files, we write
+log messages for files with NULL file names.  This means that our assumption
+of always being able to call "db_open" on any log_register OPEN message found
+in the log is no longer valid.
+
+B.1. If you try to open a file and it exists but is 0-length, then
+someone else is trying to open it.
+
+As discussed for A.1, this is no longer true.  It may be instead that you
+are in the process of recovering a create.
+
+B.2. You can write pages anywhere in a file and any non-existent pages
+are 0-filled.
+
+It turns out that this is not true on Windows.  This means that places
+we do group allocation (hash) must explicitly allocate each page, because
+we can't count on recognizing the uninitialized pages later.
+
+B.3. If you have proper permissions then you can always evict pages from
+the buffer pool.
+
+In the brave new world though, files can be deleted and they may
+have pages in the mpool.  If you later try to evict these, you
+discover that the file doesn't exist.  We'd get here when we had
+to dirty pages during a remove operation.
+
+B.4. You can close files any time you want.
+
+However, if the file takes part in the open/remove transaction,
+then we had better not close it until after the transaction
+commits/aborts, because we need to be able to get our hands on the
+dbp and the open happened in a different transaction.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+Design for recovering file create and delete in the presence of subdatabases.
+
+Assumptions:
+	Remove the O_TRUNCATE flag.
+	Single-thread all open/create/delete operations.
+		(Well, almost all; we'll optimize opens without DB_CREATE set.)
+		The reasoning for this is that with two simultaneous
+		open/creaters, during recovery, we cannot identify which
+		transaction successfully created files and therefore cannot
+		recovery correctly.
+	File system creates/deletes are synchronous
+	Once the file is open, subdatabase creates look like regular
+		get/put operations and a metadata page creation.
+
+There are 4 cases to deal with:
+	1. Open/create file
+	2. Open/create subdatabase
+	3. Delete
+	4. Recovery records
+
+		__db_fileopen_recover
+		__db_metapage_recover
+		__db_delete_recover
+		existing c_put and c_get routines for subdatabase creation
+
+	Note that the open/create of the file and the open/create of the
+	subdatabase need to be in the same transaction.
+
+1. Open/create (full file and subdb version)
+
+If create
+	LOCK_FILEOP
+	txn_begin
+	log create message (open message below)
+	do file system open/create
+	if we did not create
+		abort transaction (before going to open_only)
+		if (!subdb)
+			set dbp->open_txn = NULL
+		else
+			txn_begin a new transaction for the subdb open
+
+	construct meta-data page
+	log meta-data page (see metapage)
+	write the meta-data page
+	* It may be the case that btrees need to log both meta-data pages
+	  and root pages. If that is the case, I believe that we can use
+	  this same record and recovery routines for both
+
+	txn_commit
+	UNLOCK_FILEOP
+
+2. Delete
+	LOCK_FILEOP
+	txn_begin
+	log delete message (delete message below)
+	mv file __db.file.lsn
+	txn_commit
+	unlink __db.file.lsn
+	UNLOCK_FILEOP
+
+3. Recovery Routines
+
+__db_fileopen_recover
+	if (argp->name.size == 0
+		done;
+
+	if (redo)	/* Commit */
+		__os_open(argp->name, DB_OSO_CREATE, argp->mode, &fh)
+		__os_closehandle(fh)
+	if (undo)	/* Abort */
+		if (argp->name exists)
+			unlink(argp->name);
+
+__db_metapage_recover
+	if (redo)
+		__os_open(argp->name, 0, 0, &fh)
+		__os_lseek(meta data page)
+		__os_write(meta data page)
+		__os_closehandle(fh);
+	if (undo)
+		done = 0;
+		if (argp->name exists)
+			if (length of argp->name != 0)
+				__os_open(argp->name, 0, 0, &fh)
+				__os_lseek(meta data page)
+				__os_read(meta data page)
+				if (read succeeds && page lsn != current_lsn)
+					done = 1
+				__os_closehandle(fh);
+			if (!done)
+				unlink(argp->name)
+
+__db_delete_recover
+	if (redo)
+		Check if the backup file still exists and if so, delete it.
+
+	if (undo)
+		if (__db_appname(__db.file.lsn exists))
+			mv __db_appname(__db.file.lsn) __db_appname(file)
+
+__db_metasub_recover
+	/* This is like a normal recovery routine */
+	Get the metadata page
+	if (cmp_n && redo)
+		copy the log page onto the page
+		update the lsn
+		make sure page gets put dirty
+	else if (cmp_p && undo)
+		update the lsn to the lsn in the log record
+		make sure page gets put dirty
+
+	if the page was modified, put it back dirty

+Testing recoverability of create/delete.
+
+These tests are unlike other tests in that they are going to
+require hooks in the library.  The reason is that the create
+and delete calls are internally wrapped in a transaction, so
+that if the call returns, the transaction has already either
+commited or aborted.  Using only that interface limits what
+kind of testing we can do.  To match our other recovery testing
+efforts, we need to add hooks to trigger aborts at particular
+times in the create/delete path.
+
+The general recovery testing strategy is that we wish to
+execute every path through every recovery routine.  That
+means that we try to:
+	catch each operation in its pre-operation state
+		call the recovery function with redo
+		call the recovery function with undo
+	catch each operation in its post-operation state
+		call the recovery function with redo
+		call the recovery function with undo
+
+In addition, there are a few critical points in the create and
+delete path that we want to make sure we capture.
+
+1. Test Structure
+
+The test structure should be similar to the existing recovery
+tests.  We will want to have a structure in place where we
+can execute different commands:
+	create a file/database
+	create a file that will contain subdatabases.
+	create a subdatabase
+	remove a subdatabase (that contains valid data)
+	remove a subdatabase (that does not contain any data)
+	remove a file that used to contain subdatabases
+	remove a file that contains a database
+
+The tricky part is capturing the state of the world at the
+various points in the create/delete process.
+
+The critical points in the create process are:
+
+	1. After we've logged the create, but before we've done anything.
+		in db/db.c
+		after the open_retry
+		after the __crdel_fileopen_log call (and before we've
+			called __os_open).
+
+	2. Immediately after the __os_open
+
+	3. Immediately after each __db_log_page call
+		in bt_open.c
+			log meta-data page
+			log root page
+		in hash.c
+			log meta-data page
+
+	4. With respect to the log records above, shortly after each
+		log write is an memp_fput.  We need to do a sync after
+		each memp_fput and trigger a point after that sync.
+
+The critical points in the remove process are:
+
+	1. Right after the crdel_delete_log in db/db.c
+
+	2. Right after the __os_rename call (below the crdel_delete_log)
+
+	3. After the __db_remove_callback call.
+
+I believe that there are the places where we'll need some sort of hook.
+
+2. Adding hooks to the library.
+
+The hooks need two components.  One component is to capture the state of
+the database at the hook point and the other is to trigger a txn_abort at
+the hook point.  The second part is fairly trivial.
+
+The first part requires more thought.  Let me explain what we do in a
+"normal" recovery test.  In a normal recovery test, we save an intial
+copy of the database (this copy is called init).  Then we execute one
+or more operations.  Then, right before the commit/abort, we sync the
+file, and save another copy (the afterop copy).  Finally, we call txn_commit
+or txn_abort, sync the file again, and save the database one last time (the
+final copy).
+
+Then we run recovery.  The first time, this should be a no-op, because
+we've either committed the transaction and are checking to redo it or
+we aborted the transaction, undid it on the abort and are checking to
+undo it again.
+
+We then run recovery again on whatever database will force us through
+the path that requires work.  In the commit case, this means we start
+with the init copy of the database and run recovery.  This pushes us
+through all the redo paths.  In the abort case, we start with the afterop
+copy which pushes us through all the undo cases.
+
+In some sense, we're asking the create/delete test to be more exhaustive
+by defining all the trigger points, but I think that's the correct thing
+to do, since the create/delete is not initiated by a user transaction.
+
+So, what do we have to do at the hook points?
+	1. sync the file to disk.
+	2. save the file itself
+	3. save any files named __db_backup_name(name, &backup_name, lsn)
+		Since we may not know the right lsns, I think we should save
+		every file of the form __db.name.0xNNNNNNNN.0xNNNNNNNN into
+		some temporary files from which we can restore it to run
+		recovery.
+
+3. Putting it all together
+
+So, the three pieces are writing the test structure, putting in the hooks
+and then writing the recovery portions so that we restore the right thing
+that the hooks saved in order to initiate recovery.
+
+Some of the technical issues that need to be solved are:
+	How does the hook code become active (i.e., we don't
+		want it in there normally, but it's got to be
+		there when you configure for testing)?
+	How do you (the test) tell the library that you want a
+		particular hook to abort?
+	How do you (the test) tell the library that you want the
+		hook code doing its copies (do we really want
+		*every* test doing these copies during testing?
+		Maybe it's not a big deal, but maybe it is; we
+		should at least think about it).

+# logging. It also generates a template for the recovery functions (these

+# template gets you a fair way along the path).
+#
+# For a given file prefix.src, we generate a file prefix_auto.c, and a file
+# prefix_auto.h that contains:
+#
+#	external declarations for the file's functions
+# 	defines for the physical record types
+#	    (logical types are defined in each subsystem manually)
+#	structures to contain the data unmarshalled from the log.
+#
+# This awk script requires that five variables be set when it is called:
+#
+#	source_file	-- the C source file being created
+#	subsystem	-- the subsystem prefix, e.g., "db"
+#	header_file	-- the C #include file being created
+#	template_file	-- the template file being created
+#	template_dir	-- the directory to find the source template
+#

+# This awk script requires that these variables be set when it is called:
+#
+#	client_file	-- the C source file being created for client code
+#	cproto_file	-- the header file create for client prototypes
+#	ctmpl_file	-- the C template file being created for client code
+#	sed_file	-- the sed file created to alter server proc code
+#	server_file	-- the C source file being created for server code
+#	sproto_file	-- the header file create for server prototypes
+#	stmpl_file	-- the C template file being created for server code
+#	xdr_file	-- the XDR message file created
+#
+# And stdin must be the input file that defines the RPC setup.

+LINK-COMMAND is a command using the C compiler that you would use to create
+a program from several object files.
+
+The following components of LINK-COMMAND are treated specially:
+
+  -all-static       do not do any dynamic linking at all
+  -avoid-version    do not add a version suffix if possible
+  -dlopen FILE      \`-dlpreopen' FILE if it cannot be dlopened at runtime
+  -dlpreopen FILE   link in FILE and add its symbols to lt_preloaded_symbols
+  -export-dynamic   allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
+  -export-symbols SYMFILE
+		    try to export only the symbols listed in SYMFILE
+  -export-symbols-regex REGEX
+		    try to export only the symbols matching REGEX
+  -LLIBDIR          search LIBDIR for required installed libraries
+  -lNAME            OUTPUT-FILE requires the installed library libNAME
+  -module           build a library that can dlopened
+  -no-undefined     declare that a library does not refer to external symbols
+  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
+  -release RELEASE  specify package release information
+  -rpath LIBDIR     the created library will eventually be installed in LIBDIR
+  -R[ ]LIBDIR       add LIBDIR to the runtime path of programs and libraries
+  -static           do not do any dynamic linking of libtool libraries
+  -version-info CURRENT[:REVISION[:AGE]]
+		    specify library version info [each variable defaults to 0]
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename.  Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.
+
+If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
+using \`ar' and \`ranlib', or on Windows using \`lib'.
+
+If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file

+<h3><pre>
+#include &lt;db.h&gt;
+<p>
+int
+DB-&gt;close(DB *db, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The DB-&gt;close function flushes any cached database information to disk,
+closes any open cursors, frees any allocated resources, and closes any
+underlying files.  Since key/data pairs are cached in memory, failing to
+sync the file with the DB-&gt;close or <a href="../api_c/db_sync.html">DB-&gt;sync</a> function may result
+in inconsistent or lost information.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_NOSYNC">DB_NOSYNC</a><dd>Do not flush cached information to disk.
+<p>The <a href="../api_c/db_close.html#DB_NOSYNC">DB_NOSYNC</a> flag is a dangerous option.  It should only be set
+if the application is doing logging (with transactions) so that the
+database is recoverable after a system or application crash, or if the
+database is always generated from scratch after any system or application
+crash.
+<p><b>It is important to understand that flushing cached information to disk
+only minimizes the window of opportunity for corrupted data.</b>
+While unlikely, it is possible for database corruption to happen if a
+system or application crash occurs while writing data to the database.
+To ensure that database corruption never occurs, applications must either:
+use transactions and logging with automatic recovery, use logging and
+application-specific recovery, or edit a copy of the database,
+and, once all applications using the database have successfully called
+DB-&gt;close, atomically replace the original database with the
+updated copy.
+</dl>
+<p>When multiple threads are using the Berkeley DB handle concurrently, only a single
+thread may call the DB-&gt;close function.
+<p>Once DB-&gt;close has been called, regardless of its return, the
+DB handle may not be accessed again.
+        <a name="3"><!--meow--></a>    
+<p>The DB-&gt;close function returns a non-zero error value on failure, 0 on success, and returns <a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> if the underlying database still has
+dirty pages in the cache.  (The only reason to return
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> is if another thread of control was writing pages
+in the underlying database file at the same time as the
+DB-&gt;close function was called.  For this reason, a return of
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> can normally be ignored, or, in cases where it is
+a possible return value, the <a href="../api_c/db_close.html#DB_NOSYNC">DB_NOSYNC</a> option should probably
+have been specified.)
+<p>The DB-&gt;close function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The DB-&gt;close function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the DB-&gt;close function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The db_create function creates a DB structure which is the
+handle for a Berkeley DB database.  A pointer to this structure is returned
+in the memory referenced by <b>db</b>.
+<p>If the <b>dbenv</b> argument is NULL, the database is standalone, i.e.,
+it is not part of any Berkeley DB environment.
+<p>If the <b>dbenv</b> argument is not NULL, the database is created within
+the specified Berkeley DB environment.  The database access methods
+automatically make calls to the other subsystems in Berkeley DB based on the
+enclosing environment.  For example, if the environment has been
+configured to use locking, then the access methods will automatically
+acquire the correct locks when reading and writing pages of the database.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_XA_CREATE">DB_XA_CREATE</a><dd>Instead of creating a standalone database, create a database intended to
+be accessed via applications running under a X/Open conformant Transaction
+Manager.  The database will be opened in the environment specified by the
+OPENINFO parameter of the GROUPS section of the ubbconfig file.  See the
+<a href="../ref/xa/intro.html">XA Resource Manager</a> chapter in the
+Reference Guide for more information.
+</dl>
+<p>The DB handle contains a special field, "app_private", which
+is declared as type "void *".  This field is provided for the use of
+the application program.  It is initialized to NULL and is not further
+used by Berkeley DB in any way.
+<p>The db_create function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The db_create function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the db_create function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<h1>Description</h1>
+<p>The DB-&gt;del function removes key/data pairs from the database.  The
+key/data pair associated with the specified <b>key</b> is discarded from
+the database.  In the presence of duplicate key values, all records
+associated with the designated key will be discarded.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_c/txn_begin.html">txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>The DB-&gt;del function returns a non-zero error value on failure, 0 on success, and <a href="../ref/program/errorret.html#DB_NOTFOUND">DB_NOTFOUND</a> if the specified <b>key</b> did not exist in
+the file.
+<h1>Errors</h1>

+<p><dt>DB_LOCK_DEADLOCK<dd>The operation was selected to resolve a deadlock.

+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+</dl>
+<p>The DB-&gt;del function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the DB-&gt;del function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<h1>Description</h1>
+<p>The DBENV-&gt;err, DBENV-&gt;errx,  DB-&gt;err and
+DB-&gt;errx functions provide error messaging functionality for
+applications written using the Berkeley DB library.
+<p>The DBENV-&gt;err function constructs an error message consisting of the
+following elements:
+<p><blockquote><p><dl compact>
+<p><dt>An optional prefix string<dd>If no error callback function has been set using the
+<a href="../api_c/env_set_errcall.html">DBENV-&gt;set_errcall</a> function, any prefix string specified using the
+<a href="../api_c/env_set_errpfx.html">DBENV-&gt;set_errpfx</a> function, followed by two separating characters: a colon
+and a &lt;space&gt; character.
+<p><dt>An optional printf-style message<dd>The supplied message <b>fmt</b>, if non-NULL, where the ANSI C X3.159-1989 (ANSI C)
+printf function specifies how subsequent arguments are converted for
+output.
+<p><dt>A separator<dd>Two separating characters: a colon and a &lt;space&gt; character.
+<p><dt>A standard error string<dd>The standard system or Berkeley DB library error string associated with the
+<b>error</b> value, as returned by the <a href="../api_c/env_strerror.html">db_strerror</a> function.
+</dl>
+</blockquote>
+<p>This constructed error message is then handled as follows:
+<p><blockquote>
+<p>If an error callback function has been set (see <a href="../api_c/db_set_errcall.html">DB-&gt;set_errcall</a>
+and <a href="../api_c/env_set_errcall.html">DBENV-&gt;set_errcall</a>), that function is called with two
+arguments: any prefix string specified (see <a href="../api_c/db_set_errpfx.html">DB-&gt;set_errpfx</a> and
+<a href="../api_c/env_set_errpfx.html">DBENV-&gt;set_errpfx</a>), and the error message.
+<p>If a C library FILE * has been set (see <a href="../api_c/db_set_errfile.html">DB-&gt;set_errfile</a> and
+<a href="../api_c/env_set_errfile.html">DBENV-&gt;set_errfile</a>), the error message is written to that output
+stream.
+<p>If none of these output options has been configured, the error message
+is written to stderr, the standard error output stream.</blockquote>
+<p>The DBENV-&gt;errx and DB-&gt;errx functions perform identically to the
+DBENV-&gt;err and DB-&gt;err functions except that they do not append
+the final separator characters and standard error string to the error
+message.

+<p>The DB-&gt;fd function only supports a coarse-grained form of locking.
+Applications should use the lock manager where possible.
+<p>The DB-&gt;fd function returns a non-zero error value on failure and 0 on success.

+</pre></h3>
+<h1>Description</h1>
+<p>The DB-&gt;get function retrieves key/data pairs from the database.  The
+address
+and length of the data associated with the specified <b>key</b> are
+returned in the structure referenced by <b>data</b>.
+<p>In the presence of duplicate key values, DB-&gt;get will return the
+first data item for the designated key.  Duplicates are sorted by insert
+order except where this order has been overridden by cursor operations.
+<b>Retrieval of duplicates requires the use of cursor operations.</b>
+See <a href="../api_c/dbc_get.html">DBcursor-&gt;c_get</a> for details.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_c/txn_begin.html">txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_CONSUME">DB_CONSUME</a><dd>Return the record number and data from the available record closest to
+the head of the queue and delete the record.  The cursor will be
+positioned on the deleted record.  The record number will be returned
+in <b>key</b> as described in <a href="../api_c/dbt.html">DBT</a>.  The data will be returned
+in the <b>data</b> parameter.  A record is available if it is not
+deleted and is not currently locked.  The underlying database must be
+of type Queue for DB_CONSUME to be specified.
+<p><dt><a name="DB_CONSUME_WAIT">DB_CONSUME_WAIT</a><dd>The DB_CONSUME_WAIT flag is the same as the DB_CONSUME
+flag except that if the Queue database is empty, the thread of control
+will wait until there is data in the queue before returning.  The
+underlying database must be of type Queue for DB_CONSUME_WAIT
+to be specified.
+<p><dt><a name="DB_GET_BOTH">DB_GET_BOTH</a><dd>Retrieve the key/data pair only if both the key and data match the
+arguments.
+<p><dt><a name="DB_SET_RECNO">DB_SET_RECNO</a><dd>Retrieve the specified numbered key/data pair from a database.
+Upon return, both the <b>key</b> and <b>data</b> items will have been
+filled in, not just the data item as is done for all other uses of the
+DB-&gt;get function.
+<p>The <b>data</b> field of the specified <b>key</b>
+must be a pointer to a logical record number (i.e., a <b>db_recno_t</b>).
+This record number determines the record to be retrieved.
+<p>For DB_SET_RECNO to be specified, the underlying database must be
+of type Btree and it must have been created with the DB_RECNUM flag.
+</dl>
+<p>In addition, the following flag may be set by bitwise inclusively <b>OR</b>'ing it into the
+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="DB_RMW">DB_RMW</a><dd>Acquire write locks instead of read locks when doing the retrieval.
+Setting this flag may decrease the likelihood of deadlock during a
+read-modify-write cycle by immediately acquiring the write lock during
+the read part of the cycle so that another thread of control acquiring
+a read lock for the same item, in its own read-modify-write cycle, will
+not result in deadlock.
+<p>As the DB-&gt;get interface will not hold locks across
+Berkeley DB interface calls in non-transactional environments, the
+<a href="../api_c/dbc_get.html#DB_RMW">DB_RMW</a> flag to the DB-&gt;get call is only meaningful in
+the presence of transactions.
+</dl>
+<p>If the database is a Queue or Recno database and the requested key exists,
+but was never explicitly created by the application or was later deleted,
+the DB-&gt;get function returns <a href="../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a>.
+<p>Otherwise, if the requested key is not in the database, the
+DB-&gt;get function returns <a href="../ref/program/errorret.html#DB_NOTFOUND">DB_NOTFOUND</a>.
+<p>Otherwise, the DB-&gt;get function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The DB-&gt;get function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>DB_LOCK_DEADLOCK<dd>The operation was selected to resolve a deadlock.
+</dl>
+<p><dl compact>
+<p><dt>ENOMEM<dd>There was insufficient memory to return the requested item.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>A record number of 0 was specified.
+<p>The <a href="../api_c/env_open.html#DB_THREAD">DB_THREAD</a> flag was specified to the
+<a href="../api_c/db_open.html">DB-&gt;open</a> function and none of the <a href="../api_c/dbt.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a>,
+<a href="../api_c/dbt.html#DB_DBT_REALLOC">DB_DBT_REALLOC</a> or <a href="../api_c/dbt.html#DB_DBT_USERMEM">DB_DBT_USERMEM</a> flags were set in the
+<a href="../api_c/dbt.html">DBT</a>.
+</dl>
+<p>The DB-&gt;get function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the DB-&gt;get function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<p>
+int
+DB-&gt;join(DB *primary,
+	DBC **curslist, DBC **dbcp, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The DB-&gt;join function creates a specialized cursor for use in performing
+joins on secondary indexes.  For information on how to organize your data
+to use this functionality, see <a href="../ref/am/join.html">Logical
+join</a>.
+<p>The <b>primary</b> argument contains the DB handle of the primary
+database, which is keyed by the data values found in entries in the
+<b>curslist</b>.
+<p>The <b>curslist</b> argument contains a NULL terminated array of cursors.
+Each cursor must have been initialized to reference the key on which the
+underlying database should be joined.  Typically, this initialization is done
+by a <a href="../api_c/dbc_get.html">DBcursor-&gt;c_get</a> call with the <a href="../api_c/dbc_get.html#DB_SET">DB_SET</a> flag specified.  Once the
+cursors have been passed as part of a <b>curslist</b>, they should not
+be accessed or modified until the newly created join cursor has been closed,
+or else inconsistent results may be returned.
+<p>Joined values are retrieved by doing a sequential iteration over the first
+cursor in the <b>curslist</b> argument, and a nested iteration over each
+secondary cursor in the order they are specified in the <b>curslist</b>
+argument.  This requires database traversals to search for the current
+datum in all the cursors after the first.  For this reason, the best join
+performance normally results from sorting the cursors from the one that
+references the least number of data items to the one that references the
+most.  By default, DB-&gt;join does this sort on behalf of its caller.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_JOIN_NOSORT">DB_JOIN_NOSORT</a><dd>Do not sort the cursors based on the number of data items they reference.
+If the data are structured such that cursors with many data items also
+share many common elements, higher performance will result from listing
+those cursors before cursors with fewer data items, that is, a sort order
+other than the default.  The DB_JOIN_NOSORT flag permits
+applications to perform join optimization prior to calling DB-&gt;join.
+</dl>
+<p>A newly created cursor is returned in the memory location referenced by
+<b>dbcp</b> and has the standard cursor functions:
+<p><dl compact>

+<h1>Description</h1>
+<p>The DB-&gt;key_range function returns an estimate of the proportion of keys
+that are less than, equal to and greater than the specified key.  The
+underlying database must be of type Btree.
+<p>The information is returned in the <b>key_range</b> argument, which
+contains three elements of type double, <b>less</b>, <b>equal</b> and
+<b>greater</b>.  Values are in the range of 0 to 1, e.g., if the field
+<b>less</b> is 0.05, that indicates that 5% of the keys in the database
+are less than the key argument.  The value for <b>equal</b> will be zero
+if there is no matching key and non-zero otherwise.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_c/txn_begin.html">txn_begin</a>, otherwise, NULL.
+The DB-&gt;key_range function does not retain the locks it acquires for the
+life of the transaction, so estimates may not be repeatable.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>The DB-&gt;key_range function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>

+<h1>Description</h1>
+<p>The currently supported Berkeley DB file formats (or <i>access methods</i>)
+are Btree, Hash, Queue and Recno.  The Btree format is a representation
+of a sorted, balanced tree structure.  The Hash format is an extensible,
+dynamic hashing scheme.  The Queue format supports fast access to
+fixed-length records accessed by sequentially or logical record number.
+The Recno format supports fixed- or variable-length records, accessed
+sequentially or by logical record number, and optionally retrieved from
+a flat text file.
+<p>Storage and retrieval for the Berkeley DB access methods are based on key/data
+pairs, see <a href="../api_c/dbt.html">DBT</a> for more information.
+<p>The DB-&gt;open interface opens the database represented by the
+<b>file</b> and <b>database</b> arguments for both reading and writing.
+The <b>file</b> argument is used as the name of a physical file on disk
+that will be used to back the database.  The <b>database</b> argument is
+optional and allows applications to have multiple logical databases in a
+single physical file.  While no <b>database</b> argument needs to be
+specified, it is an error to attempt to open a second database in a
+<b>file</b> that was not initially created using a <b>database</b> name.
+In-memory databases never intended to be preserved on disk may
+be created by setting both the <b>file</b> and <b>database</b> arguments
+to NULL.  Note that in-memory databases can only ever be shared by
+sharing the single database handle that created them, in circumstances
+where doing so is safe.
+<p>The <b>type</b> argument is of type DBTYPE
+and must be set to one of DB_BTREE, DB_HASH,
+DB_QUEUE, DB_RECNO or DB_UNKNOWN, except
+that databases of type DB_QUEUE are restricted to one per
+<b>file</b>.  If <b>type</b> is DB_UNKNOWN, the database must
+already exist and DB-&gt;open will automatically determine its type.
+The <a href="../api_c/db_get_type.html">DB-&gt;get_type</a> function may be used to determine the underlying type of
+databases opened using DB_UNKNOWN.
+<p>The <b>flags</b> and <b>mode</b> arguments specify how files will be opened
+and/or created if they do not already exist.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_CREATE">DB_CREATE</a><dd>Create any underlying files, as necessary.  If the files do not already
+exist and the DB_CREATE flag is not specified, the call will fail.
+<p><dt><a name="DB_EXCL">DB_EXCL</a><dd>Return an error if the file already exists.  Underlying filesystem
+primitives are used to implement this flag.  For this reason it is only
+applicable to the physical file and cannot be used to test if a database
+in a file already exists.
+<p>The DB_EXCL flag is only meaningful when specified with the
+DB_CREATE flag.
+<p><dt><a name="DB_NOMMAP">DB_NOMMAP</a><dd>Do not map this database into process memory (see the description of the
+<a href="../api_c/env_set_mp_mmapsize.html">DBENV-&gt;set_mp_mmapsize</a> function for further information).
+<p><dt><a name="DB_RDONLY">DB_RDONLY</a><dd>Open the database for reading only.  Any attempt to modify items in the
+database will fail regardless of the actual permissions of any underlying
+files.
+<p><dt><a name="DB_THREAD">DB_THREAD</a><dd>Cause the DB handle returned by DB-&gt;open to be
+<i>free-threaded</i>, that is, useable by multiple threads within a
+single address space.
+<p><dt><a name="DB_TRUNCATE">DB_TRUNCATE</a><dd>Physically truncate the underlying file, discarding all previous databases
+it might have held.  Underlying filesystem primitives are used to
+implement this flag.  For this reason it is only applicable to the
+physical file and cannot be used to discard databases within a file.
+<p>The DB_TRUNCATE flag cannot be transaction protected, and it is
+an error to specify it in a transaction protected environment.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by the access methods
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>Calling DB-&gt;open is a reasonably expensive operation, and
+maintaining a set of open databases will normally be preferable to
+repeatedly open and closing the database for each new query.
+<p>The DB-&gt;open function returns a non-zero error value on failure and 0 on success.

+<p>
+int
+DB-&gt;put(DB *db,
+    DB_TXN *txnid, DBT *key, DBT *data, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The DB-&gt;put function stores key/data pairs in the database.  The default
+behavior of the DB-&gt;put function is to enter the new key/data
+pair, replacing any previously existing key if duplicates are disallowed,
+or adding a duplicate data item if duplicates are allowed.  If the database
+supports duplicates, the DB-&gt;put function adds the new data value at the
+end of the duplicate set.  If the database supports sorted duplicates,
+the new data value is inserted at the correct sorted location.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_c/txn_begin.html">txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_APPEND">DB_APPEND</a><dd>Append the key/data pair to the end of the database.  For the
+DB_APPEND flag to be specified, the underlying database must be
+a Queue or Recno database.  The record number allocated to the record is
+returned in the specified <b>key</b>.
+<p>There is a minor behavioral difference between the Recno and Queue access
+methods for the DB_APPEND flag.  If a transaction enclosing a
+DB-&gt;put operation with the DB_APPEND flag aborts, the
+record number may be decremented (and later re-allocated by a subsequent
+DB_APPEND operation) by the Recno access method, but will not be
+decremented or re-allocated by the Queue access method.
+<p><dt><a name="DB_NODUPDATA">DB_NODUPDATA</a><dd>In the case of the Btree and Hash access methods, enter the new key/data
+pair only if it does not already appear in the database.  If the
+key/data pair already appears in the database, <a href="../api_c/dbc_put.html#DB_KEYEXIST">DB_KEYEXIST</a> is
+returned.  The DB_NODUPDATA flag may only be specified if the
+underlying database has been configured to support sorted duplicates.
+<p>The DB_NODUPDATA flag may not be specified to the Queue or Recno
+access methods.
+<p><dt><a name="DB_NOOVERWRITE">DB_NOOVERWRITE</a><dd>Enter the new key/data pair only if the key does not already appear in
+the database.  If the key already appears in the database,
+<a href="../api_c/dbc_put.html#DB_KEYEXIST">DB_KEYEXIST</a> is returned.  Even if the database allows duplicates,
+a call to DB-&gt;put with the DB_NOOVERWRITE flag set will
+fail if the key already exists in the database.
+</dl>
+<p>Otherwise, the DB-&gt;put function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The DB-&gt;put function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>DB_LOCK_DEADLOCK<dd>The operation was selected to resolve a deadlock.
+</dl>
+<p><dl compact>
+<p><dt>EACCES<dd>An attempt was made to modify a read-only database.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>A record number of 0 was specified.
+<p>An attempt was made to add a record to a fixed-length database that was too
+large to fit.
+<p>An attempt was made to do a partial put.
+</dl>
+<p><dl compact>
+<p><dt>ENOSPC<dd>A btree exceeded the maximum btree depth (255).
+</dl>
+<p>The DB-&gt;put function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the DB-&gt;put function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>Set the Btree key comparison function.  The comparison function is
+called when it is necessary to compare a key specified by the
+application with a key currently stored in the tree.  The first argument
+to the comparison function is the <a href="../api_c/dbt.html">DBT</a> representing the
+application supplied key, the second is the current tree's key.
+<p>The comparison function must return an integer value less than, equal
+to, or greater than zero if the first key argument is considered to be
+respectively less than, equal to, or greater than the second key
+argument.  In addition, the comparison function must cause the keys in
+the database to be <i>well-ordered</i>.  The comparison function
+must correctly handle any key values used by the application (possibly
+including zero-length keys).  In addition, when Btree key prefix
+comparison is being performed (see <a href="../api_c/db_set_bt_prefix.html">DB-&gt;set_bt_prefix</a> for more
+information), the comparison routine may be passed a prefix of any
+database key.  The <b>data</b> and <b>size</b> fields of the
+<a href="../api_c/dbt.html">DBT</a> are the only fields that may be used for the purposes of
+this comparison.
+<p>If no comparison function is specified, the keys are compared lexically,
+with shorter keys collating before longer keys.  The same comparison
+method must be used each time a particular Btree is opened.
+<p>The DB-&gt;set_bt_compare interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.
+<p>The DB-&gt;set_bt_compare function returns a non-zero error value on failure and 0 on success.

+<h1>Description</h1>
+<p>Set the Btree prefix function.  The prefix function must return the
+number of bytes of the second key argument that would be required by
+the Btree key comparison function to determine the second key argument's
+ordering relationship with respect to the first key argument.  If the
+two keys are equal, the key length should be returned.  The prefix
+function must correctly handle any key values used by the application
+(possibly including zero-length keys).  The <b>data</b> and
+<b>size</b> fields of the <a href="../api_c/dbt.html">DBT</a> are the only fields that may be
+used for the purposes of this determination.
+<p>The prefix function is used to determine the amount by which keys stored
+on the Btree internal pages can be safely truncated without losing their
+uniqueness.  See the <a href="../ref/am_conf/bt_prefix.html">Btree
+prefix comparison</a> section of the Reference Guide for more details about
+how this works.  The usefulness of this is data dependent, but in some
+data sets can produce significantly reduced tree sizes and search times.
+<p>If no prefix function or key comparison function is specified by the
+application, a default lexical comparison function is used as the prefix
+function.  If no prefix function is specified and a key comparison
+function is specified, no prefix function is used.  It is an error to
+specify a prefix function without also specifying a key comparison
+function.
+<p>The DB-&gt;set_bt_prefix interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.

+DB-&gt;set_cachesize(DB *db,
+    u_int32_t gbytes, u_int32_t bytes, int ncache);
+</pre></h3>
+<h1>Description</h1>
+<p>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.  For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>As databases opened within Berkeley DB environments use the cache specified to
+the environment, it is an error to attempt to set a cache in a database
+created within an environment.
+<p>The DB-&gt;set_cachesize interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.
+<p>The DB-&gt;set_cachesize function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.

+<h1>Description</h1>
+<p>Set the duplicate data item comparison function.  The comparison function
+is called when it is necessary to compare a data item specified by the
+application with a data item currently stored in the tree.  The first
+argument to the comparison function is the <a href="../api_c/dbt.html">DBT</a> representing the
+application's data item, the second is the current tree's data item.
+<p>The comparison function must return an integer value less than, equal
+to, or greater than zero if the first data item argument is considered
+to be respectively less than, equal to, or greater than the second data
+item argument.  In addition, the comparison function must cause the data
+items in the set to be <i>well-ordered</i>.  The comparison function
+must correctly handle any data item values used by the application
+(possibly including zero-length data items).  The <b>data</b> and
+<b>size</b>  fields of the <a href="../api_c/dbt.html">DBT</a> are the only fields that may be
+used for the purposes of this comparison.
+<p>If no comparison function is specified, the data items are compared
+lexically, with shorter data items collating before longer data items.
+The same duplicate data item comparison method must be used each time
+a particular Btree is opened.
+<p>The DB-&gt;set_dup_compare interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.
+<p>The DB-&gt;set_dup_compare function returns a non-zero error value on failure and 0 on success.

+</pre></h3>
+<h1>Description</h1>
+When an error occurs in the Berkeley DB library, a Berkeley DB error or an error
+return value is returned by the function.  In some cases, however,
+the <b>errno</b> value may be insufficient to completely describe
+the cause of the error especially during initial application debugging.
+<p>The DB-&gt;set_errcall function is used to enhance the mechanism for reporting error
+messages to the application.  In some cases, when an error occurs, Berkeley DB
+will call <b>db_errcall_fcn</b> with additional error information.  The
+function must be declared with two arguments; the first will be the prefix
+string (as previously set by <a href="../api_c/db_set_errpfx.html">DB-&gt;set_errpfx</a> or
+<a href="../api_c/env_set_errpfx.html">DBENV-&gt;set_errpfx</a>), the second will be the error message string.
+It is up to the <b>db_errcall_fcn</b> function to display the error
+message in an appropriate manner.
+<p>Alternatively, you can use the <a href="../api_c/db_set_errfile.html">DB-&gt;set_errfile</a> or
+<a href="../api_c/env_set_errfile.html">DBENV-&gt;set_errfile</a> functions to display the additional information
+via a C library FILE *.
+<p>This error logging enhancement does not slow performance or significantly
+increase application size, and may be run during normal operation as well
+as during application debugging.
+<p>For DB handles opened inside of Berkeley DB environments, calling the
+DB-&gt;set_errcall function affects the entire environment and is equivalent to calling
+the <a href="../api_c/env_set_errcall.html">DBENV-&gt;set_errcall</a> function.
+<p>The DB-&gt;set_errcall interface may be used to configure Berkeley DB at any time
+during the life of the application.

+<h1>Description</h1>
+When an error occurs in the Berkeley DB library, a Berkeley DB error or an error
+return value is returned by the function.  In some cases, however,
+the <b>errno</b> value may be insufficient to completely describe
+the cause of the error especially during initial application debugging.
+<p>The DB-&gt;set_errfile function is used to enhance the mechanism for reporting error
+messages to the application by setting a C library FILE * to be used for
+displaying additional Berkeley DB error messages.  In some cases, when an error
+occurs, Berkeley DB will output an additional error message to the specified
+file reference.
+<p>The error message will consist of the prefix string and a colon
+("<b>:</b>") (if a prefix string was previously specified using
+<a href="../api_c/db_set_errpfx.html">DB-&gt;set_errpfx</a> or <a href="../api_c/env_set_errpfx.html">DBENV-&gt;set_errpfx</a>), an error string, and
+a trailing &lt;newline&gt; character.
+<p>This error logging enhancement does not slow performance or significantly
+increase application size, and may be run during normal operation as well
+as during application debugging.
+<p>For DB handles opened inside of Berkeley DB environments, calling the
+DB-&gt;set_errfile function affects the entire environment and is equivalent to calling
+the <a href="../api_c/env_set_errfile.html">DBENV-&gt;set_errfile</a> function.
+<p>The DB-&gt;set_errfile interface may be used to configure Berkeley DB at any time
+during the life of the application.

+#include &lt;db.h&gt;
+<p>
+int
+DB-&gt;set_flags(DB *db, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>Calling DB-&gt;set_flags is additive, there is no way to clear flags.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<h3>Btree</h3>
+<p>The following flags may be specified for the Btree access method:
+<p><dl compact>
+<p><dt><a name="DB_DUP">DB_DUP</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+order of insertion, unless the ordering is otherwise specified by use of
+a cursor operation.  It is an error to specify both DB_DUP and
+DB_RECNUM.
+<p><dt><a name="DB_DUPSORT">DB_DUPSORT</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+duplicate comparison function.
+If the application does not specify a comparison function using the
+<a href="../api_c/db_set_dup_compare.html">DB-&gt;set_dup_compare</a> function, a default, lexical comparison will be
+used.
+It is an error to specify both DB_DUPSORT and DB_RECNUM.
+<p><dt><a name="DB_RECNUM">DB_RECNUM</a><dd>Support retrieval from the Btree using record numbers.  For more
+information, see the DB_GET_RECNO flag to the <a href="../api_c/db_get.html">DB-&gt;get</a> and
+<a href="../api_c/dbc_get.html">DBcursor-&gt;c_get</a> methods.
+<p>Logical record numbers in Btree databases are mutable in the face of
+record insertion or deletion.  See the DB_RENUMBER flag in the Recno
+access method information for further discussion.
+<p>Maintaining record counts within a Btree introduces a serious point of
+contention, namely the page locations where the record counts are stored.
+In addition, the entire tree must be locked during both insertions and
+deletions, effectively single-threading the tree for those operations.
+Specifying DB_RECNUM can result in serious performance degradation for
+some applications and data sets.
+<p>It is an error to specify both DB_DUP and DB_RECNUM.
+<p><dt><a name="DB_REVSPLITOFF">DB_REVSPLITOFF</a><dd>Turn off reverse splitting in the Btree.  As pages are emptied in a
+database, the Berkeley DB Btree implementation attempts to coalesce empty pages
+into higher-level pages in order to keep the tree as small as possible
+and minimize tree search time.  This can hurt performance in applications
+with cyclical data demands, that is, applications where the database grows
+and shrinks repeatedly.  For example, because Berkeley DB does page-level
+locking, the maximum level of concurrency in a database of 2 pages is far
+smaller than that in a database of 100 pages, and so a database that has
+shrunk to a minimal size can cause severe deadlocking when a new cycle of
+data insertion begins.
+</dl>
+<h3>Hash</h3>
+<p>The following flags may be specified for the Hash access method:
+<p><dl compact>
+<p><dt><a name="DB_DUP">DB_DUP</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+order of insertion, unless the ordering is otherwise specified by use of
+a cursor operation.  It is an error to specify both DB_DUP and
+DB_RECNUM.
+<p><dt><a name="DB_DUPSORT">DB_DUPSORT</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+duplicate comparison function.
+If the application does not specify a comparison function using the
+<a href="../api_c/db_set_dup_compare.html">DB-&gt;set_dup_compare</a> function, a default, lexical comparison will be
+used.
+It is an error to specify both DB_DUPSORT and DB_RECNUM.
+</dl>
+<h3>Queue</h3>
+<p>There are no additional flags that may be specified for the Queue access
+method.
+<h3>Recno</h3>
+<p>The following flags may be specified for the Recno access method:
+<p><dl compact>
+<p><dt><a name="DB_RENUMBER">DB_RENUMBER</a><dd>Specifying the DB_RENUMBER flag causes the logical record numbers to be
+mutable, and change as records are added to and deleted from the database.
+For example, the deletion of record number 4 causes records numbered 5
+and greater to be renumbered downward by 1.  If a cursor was positioned
+to record number 4 before the deletion, it will reference the new record
+number 4, if any such record exists, after the deletion.  If a cursor was
+positioned after record number 4 before the deletion, it will be shifted
+downward 1 logical record, continuing to reference the same record as it
+did before.
+<p>Using the <a href="../api_c/db_put.html">DB-&gt;put</a> or <a href="../api_c/dbc_put.html">DBcursor-&gt;c_put</a> interfaces to create new
+records will cause the creation of multiple records if the record number
+is more than one greater than the largest record currently in the
+database.  For example, creating record 28, when record 25 was previously
+the last record in the database, will create records 26 and 27 as well as
+28.  Attempts to retrieve records that were created in this manner will
+result in an error return of <a href="../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a>.
+<p>If a created record is not at the end of the database, all records
+following the new record will be automatically renumbered upward by 1.
+For example, the creation of a new record numbered 8 causes records
+numbered 8 and greater to be renumbered upward by 1.  If a cursor was
+positioned to record number 8 or greater before the insertion, it will be
+shifted upward 1 logical record, continuing to reference the same record
+as it did before.
+<p>For these reasons, concurrent access to a Recno database with the
+DB_RENUMBER flag specified may be largely meaningless, although
+it is supported.
+<p><dt><a name="DB_SNAPSHOT">DB_SNAPSHOT</a><dd>This flag specifies that any specified <b>re_source</b> file be read in
+its entirety when <a href="../api_c/db_open.html">DB-&gt;open</a> is called.  If this flag is not
+specified, the <b>re_source</b> file may be read lazily.
+</dl>
+<p>The DB-&gt;set_flags interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.
+<p>The DB-&gt;set_flags function returns a non-zero error value on failure and 0 on success.

+<h1>Description</h1>
+<p>Set the desired density within the hash table.
+<p>The density is an approximation of the number of keys allowed to
+accumulate in any one bucket, determining when the hash table grows or
+shrinks.  If you know the average sizes of the keys and data in your
+dataset, setting the fill factor can enhance performance.  A reasonable
+rule computing fill factor is to set it to:
+<p><blockquote><pre>(pagesize - 32) / (average_key_size + average_data_size + 8)</pre></blockquote>
+<p>If no value is specified, the fill factor will be selected dynamically as
+pages are filled.
+<p>The DB-&gt;set_h_ffactor interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.

+<h1>Description</h1>
+<p>Set the allocation function used by the DB methods to allocate
+memory in which to return key/data items to the application.
+<p>The <a href="../api_c/dbt.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a> flag, when specified in the <a href="../api_c/dbt.html">DBT</a> object,
+will cause the DB methods to allocate and re-allocate memory which
+then becomes the responsibility of the calling application.  See <a href="../api_c/dbt.html">DBT</a>
+for more information.
+<p>On systems where there may be multiple library versions of malloc (notably
+Windows NT), specifying the <a href="../api_c/dbt.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a> flag will fail because
+the DB library will allocate memory from a different heap than
+the application will use to free it.  To avoid this problem, the
+DB-&gt;set_malloc function can be used to pass Berkeley DB a reference to the
+application's allocation routine, in which case it will be used to
+allocate the memory returned when the <a href="../api_c/dbt.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a> flag is set.
+<p>The function specified must match the calling conventions of the
+ANSI C X3.159-1989 (ANSI C) library routine of the same name.
+<p>The DB-&gt;set_malloc interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.
+<p>The DB-&gt;set_malloc function returns a non-zero error value on failure and 0 on success.

+</pre></h3>
+<h1>Description</h1>
+<p>Errors can occur in the Berkeley DB library where the only solution is to shut
+down the application and run recovery.  (For example, if Berkeley DB is unable
+to write log records to disk because there is insufficient disk space.)
+In these cases, the value <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is returned by Berkeley DB.
+<p>In these cases, it is also often simpler to shut down the application when
+such errors occur rather than attempting to gracefully return up the stack.
+The DB-&gt;set_paniccall function is used to specify a function to be called when
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is about to be returned from a Berkeley DB method.  When
+called, the <b>dbenv</b> argument will be a reference to the current
+environment, and the <b>errval</b> argument is the error value that would
+have been returned to the calling function.
+<p>For DB handles opened inside of Berkeley DB environments, calling the
+DB-&gt;set_paniccall function affects the entire environment and is equivalent to calling
+the <a href="../api_c/env_set_paniccall.html">DBENV-&gt;set_paniccall</a> function.
+<p>The DB-&gt;set_paniccall interface may be used to configure Berkeley DB at any time
+during the life of the application.
+<p>The DB-&gt;set_paniccall function returns a non-zero error value on failure and 0 on success.

+byte stream files can be interpreted as a sequence of variable length
+records separated by &lt;newline&gt; characters.
+<p>In addition, when cached data would normally be written back to the
+underlying database file (e.g., the <a href="../api_c/db_close.html">DB-&gt;close</a> or <a href="../api_c/db_sync.html">DB-&gt;sync</a>
+methods are called), the in-memory copy of the database will be written
+back to the <b>re_source</b> file.
+<p>By default, the backing source file is read lazily, i.e., records are not
+read from the file until they are requested by the application.
+<b>If multiple processes (not threads) are accessing a Recno database
+concurrently and either inserting or deleting records, the backing source
+file must be read in its entirety before more than a single process
+accesses the database, and only that process should specify the backing
+source file as part of the <a href="../api_c/db_open.html">DB-&gt;open</a> call.  See the <a href="../api_c/db_set_flags.html#DB_SNAPSHOT">DB_SNAPSHOT</a>
+flag for more information.</b>
+<p><b>Reading and writing the backing source file specified by <b>re_source</b>
+cannot be transactionally protected because it involves filesystem
+operations that are not part of the Db transaction methodology.</b>
+For this reason, if a temporary database is used to hold the records,
+i.e., a NULL was specified as the <b>file</b> argument to <a href="../api_c/db_open.html">DB-&gt;open</a>,
+it is possible to lose the contents of the <b>re_source</b> file, e.g.,
+if the system crashes at the right instant.
+If a file is used to hold the database, i.e., a file name was specified
+as the <b>file</b> argument to <a href="../api_c/db_open.html">DB-&gt;open</a>, normal database
+recovery on that file can be used to prevent information loss,
+although it is still possible that the contents of <b>re_source</b>
+will be lost if the system crashes.
+<p>The <b>re_source</b> file must already exist (but may be zero-length) when
+<a href="../api_c/db_open.html">DB-&gt;open</a> is called.
+<p>It is not an error to specify a read-only <b>re_source</b> file when
+creating a database, nor is it an error to modify the resulting database.
+However, any attempt to write the changes to the backing source file using
+either the <a href="../api_c/db_sync.html">DB-&gt;sync</a> or <a href="../api_c/db_close.html">DB-&gt;close</a> functions will fail, of course.
+Specify the <a href="../api_c/db_close.html#DB_NOSYNC">DB_NOSYNC</a> flag to the <a href="../api_c/db_close.html">DB-&gt;close</a> function to stop it
+from attempting to write the changes to the backing file, instead, they
+will be silently discarded.
+<p>For all of the above reasons, the <b>re_source</b> field is generally
+used to specify databases that are read-only for DB applications,
+and that are either generated on the fly by software tools, or modified
+using a different mechanism, e.g., a text editor.
+<p>The DB-&gt;set_re_source interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.
+<p>The DB-&gt;set_re_source function returns a non-zero error value on failure and 0 on success.

+<h1>Description</h1>
+<p>Set the realloc function used by the DB methods to allocate memory
+in which to return key/data items to the application.
+<p>The <a href="../api_c/dbt.html#DB_DBT_REALLOC">DB_DBT_REALLOC</a> flag, when specified in the <a href="../api_c/dbt.html">DBT</a> object,
+will cause the DB methods to allocate and re-allocate memory which
+then becomes the responsibility of the calling application.  See <a href="../api_c/dbt.html">DBT</a>
+for more information.
+<p>On systems where there may be multiple library versions of realloc (notably
+Windows NT), specifying the <a href="../api_c/dbt.html#DB_DBT_REALLOC">DB_DBT_REALLOC</a> flag will fail because
+the DB library will allocate memory from a different heap than
+the application will use to free it.  To avoid this problem, the
+DB-&gt;set_realloc function can be used to pass Berkeley DB a reference to the
+application's allocation routine, in which case it will be used to
+allocate the memory returned when the <a href="../api_c/dbt.html#DB_DBT_REALLOC">DB_DBT_REALLOC</a> flag is set.
+<p>The function specified must match the calling conventions of the
+ANSI C X3.159-1989 (ANSI C) library routine of the same name.
+<p>The DB-&gt;set_realloc interface may only be used to configure Berkeley DB before
+the <a href="../api_c/db_open.html">DB-&gt;open</a> interface is called.
+<p>The DB-&gt;set_realloc function returns a non-zero error value on failure and 0 on success.

+<h3><pre>

+<p>
+int
+DB-&gt;stat(DB *db,
+	void *sp, void *(*db_malloc)(size_t), u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The DB-&gt;stat function creates a statistical structure and
+copies a pointer to it into user-specified memory locations.
+Specifically, if <b>sp</b> is non-NULL, a pointer to the statistics
+for the database are copied into the memory location it references.
+<p>Statistical structures are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_CACHED_COUNTS">DB_CACHED_COUNTS</a><dd>Return a cached count of the keys and records in a database.  This flag
+makes it possible for applications to request an possibly approximate key
+and record count without incurring the performance penalty of traversing
+the entire database.  The statistics information described for the access
+method <b>XX_nkeys</b> and <b>XX_ndata</b> fields below is filled in,
+but no other information is collected.  If the cached information has
+never been set, the fields will be returned set to 0.
+<p><dt><a name="DB_RECORDCOUNT">DB_RECORDCOUNT</a><dd>Return a count of the records in a Btree or Recno Access Method database.
+This flag makes it possible for applications to request a record count
+without incurring the performance penalty of traversing the entire
+database.  The statistics information described for the <b>bt_nkeys</b>
+field below is filled in, but no other information is collected.
+<p>This option is only available for Recno databases, or Btree databases
+where the underlying database was created with the <a href="../api_c/db_set_flags.html#DB_RECNUM">DB_RECNUM</a>
+flag.
+</dl>
+<p>The DB-&gt;stat function may access all of the pages in the database,
+incurring a severe performance penalty as well as possibly flushing the
+underlying buffer pool.
+<p>In the presence of multiple threads or processes accessing an active
+database, the information returned by DB-&gt;stat may be out-of-date.
+<p>If the database was not opened readonly and the DB_CACHED_COUNTS
+flag was not specified, the cached key and record numbers will be updated
+after the statistical information has been gathered.
+<p>The DB-&gt;stat function cannot be transaction protected.  For this reason,
+it should be called in a thread of control that has no open cursors or
+active transactions.
+<p>The DB-&gt;stat function returns a non-zero error value on failure and 0 on success.
+<h3>Hash Statistics</h3>
+<p>In the case of a Hash database,
+the statistics are stored in a structure of type DB_HASH_STAT.  The
+following fields will be filled in:

+<h3>Queue Statistics</h3>
+<p>In the case of a Queue database,

+<p><dl compact>
+<p><dt>u_int32_t qs_magic;<dd>Magic number that identifies the file as a Queue file.
+<dt>u_int32_t qs_version;<dd>The version of the Queue file type.

+If a catastrophic error has occurred, the DB-&gt;stat function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The DB-&gt;sync function flushes any cached information to disk.
+<p>If the database is in memory only, the DB-&gt;sync function has no effect and
+will always succeed.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>See <a href="../api_c/db_close.html">DB-&gt;close</a> for a discussion of Berkeley DB and cached data.
+<p>The DB-&gt;sync function returns a non-zero error value on failure, 0 on success, and returns <a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> if the underlying database still has
+dirty pages in the cache.  (The only reason to return
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> is if another thread of control was writing pages
+in the underlying database file at the same time as the
+DB-&gt;sync function was being called.  For this reason, a return of
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> can normally be ignored, or, in cases where it is
+a possible return value, there may be no reason to call
+DB-&gt;sync.)
+<h1>Errors</h1>
+<p>The DB-&gt;sync function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+</dl>
+<p>The DB-&gt;sync function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the DB-&gt;sync function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+</pre></h3>
+<h1>Description</h1>
+<p>The DB-&gt;upgrade function upgrades all of the databases included in the
+file <b>file</b>, if necessary.  If no upgrade is necessary,
+DB-&gt;upgrade always returns success.
+<p><b>Database upgrades are done in place and are destructive, e.g., if pages
+need to be allocated and no disk space is available, the database may be
+left corrupted.  Backups should be made before databases are upgraded.
+See <a href="../ref/am/upgrade.html">Upgrading databases</a> for more
+information.</b>
+<p>Unlike all other database operations, DB-&gt;upgrade may only be done
+on a system with the same byte-order as the database.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_DUPSORT">DB_DUPSORT</a><dd><b>This flag is only meaningful when upgrading databases from
+releases before the Berkeley DB 3.1 release.</b>
+<p>As part of the upgrade from the Berkeley DB 3.0 release to the 3.1 release, the
+on-disk format of duplicate data items changed.  To correctly upgrade the
+format requires applications specify if duplicate data items in the
+database are sorted or not.  Specifying the DB_DUPSORT flag
+informs DB-&gt;upgrade that the duplicates are sorted, otherwise they
+are assumed to be unsorted.  Incorrectly specifying the value of this flag
+may lead to database corruption.
+<p>Further, because the DB-&gt;upgrade function upgrades a physical file
+(including all of the databases it contains), it is not possible to use
+DB-&gt;upgrade to upgrade files where some of the databases it
+includes have sorted duplicate data items and some of the databases it
+includes have unsorted duplicate data items.  If the file does not have
+more than a single database, or the databases do not support duplicate
+data items, or all of the databases that support duplicate data items
+support the same style of duplicates (either sorted or unsorted),
+DB-&gt;upgrade will work correctly as long as the DB_DUPSORT
+flag is correctly specified.  Otherwise, the file cannot be upgraded using
+DB-&gt;upgrade, and must be upgraded manually by dumping and
+re-loading the databases.
+</dl>
+<p>The DB-&gt;upgrade function returns a non-zero error value on failure and 0 on success.
+<p>The DB-&gt;upgrade function is the underlying function used by the <a href="../utility/db_upgrade.html">db_upgrade</a> utility.
+See the <a href="../utility/db_upgrade.html">db_upgrade</a> utility source code for an example of using DB-&gt;upgrade
+in a IEEE/ANSI Std 1003.1 (POSIX) environment.

+<h1>Description</h1>
+<p>The DB-&gt;verify function verifies the integrity of all databases in the
+file specified by the file argument, and optionally outputs the databases'
+key/data pairs to a file stream.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following

+<p><dl compact>
+<p><dt><a name="DB_SALVAGE">DB_SALVAGE</a><dd>Write the key/data pairs from all databases in the file to the file stream
+named in
+the <b>outfile</b> argument.  The output format is the same as that
+specified for the <a href="../utility/db_dump.html">db_dump</a> utility and can be used as input for
+the <a href="../utility/db_load.html">db_load</a> utility.
+<p>Because the key/data pairs are output in page order as opposed to the sort
+order used by <a href="../utility/db_dump.html">db_dump</a>, using DB-&gt;verify to dump key/data
+pairs normally produces less than optimal loads for Btree databases.
+</dl>
+<p>In addition, the following flags may be set by bitwise inclusively <b>OR</b>'ing them into the
+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="DB_AGGRESSIVE">DB_AGGRESSIVE</a><dd>Output <b>all</b> the key/data pairs in the file that can be found.
+By default, DB-&gt;verify does not assume corruption.  For example,
+if a key/data pair on a page is marked as deleted, it is not then written
+to the output file.  When DB_AGGRESSIVE is specified, corruption
+is assumed, and any key/data pair that can be found is written.  In this
+case, key/data pairs that are corrupted or have been deleted may appear
+in the output (even if the file being salvaged is in no way corrupt), and
+the output will almost certainly require editing before being loaded into
+a database.
+<p><dt><a name="DB_NOORDERCHK">DB_NOORDERCHK</a><dd>Skip the database checks for btree and duplicate sort order and for
+hashing.
+<p>The DB-&gt;verify function normally verifies that btree keys and duplicate
+items are correctly sorted and hash keys are correctly hashed.  If the
+file being verified contains multiple databases using differing sorting
+or hashing algorithms, some of them must necessarily fail database
+verification as only one sort order or hash function can be specified
+before DB-&gt;verify is called.  To verify files with multiple
+databases having differing sorting orders or hashing functions, first
+perform verification of the file as a whole by using the
+DB_NOORDERCHK flag, and then individually verify the sort order
+and hashing function for each database in the file using the
+DB_ORDERCHKONLY flag.
+<p><dt><a name="DB_ORDERCHKONLY">DB_ORDERCHKONLY</a><dd>Perform the database checks for btree and duplicate sort order and for
+hashing, skipped by DB_NOORDERCHK.
+<p>When this flag is specified, a <b>database</b> argument should also be
+specified, indicating the database in the physical file which is to be
+checked.  This flag is only safe to use on databases that have already
+successfully been verified using DB-&gt;verify with the
+DB_NOORDERCHK flag set.
+</dl>
+<p>The database argument must be set to NULL except when the
+DB_ORDERCHKONLY flag is set.
+<p>The DB-&gt;verify function returns a non-zero error value on failure, 0 on success, and <a href="../ref/program/errorret.html#DB_VERIFY_BAD">DB_VERIFY_BAD</a> if a database is corrupted.  When the
+DB_SALVAGE flag is specified, the <a href="../ref/program/errorret.html#DB_VERIFY_BAD">DB_VERIFY_BAD</a> return
+means that all key/data pairs in the file may not have been successfully
+output.
+<p>The DB-&gt;verify function is the underlying function used by the <a href="../utility/db_verify.html">db_verify</a> utility.

+<h1>Description</h1>
+<p>The dbm interfaces to the Berkeley DB library are intended to provide
+high-performance implementations and source code compatibility for
+applications written to historic interfaces.  They are not recommended
+for any other purpose.  The historic dbm database format
+<b>is not supported</b>, and databases previously built using the real
+dbm libraries cannot be read by the Berkeley DB functions.
+<p>To compile dbm applications, replace the application's
+<b>#include</b> of the dbm or ndbm include file (e.g.,
+<b>#include &lt;dbm.h&gt;</b> or <b>#include &lt;ndbm.h&gt;</b>)
+with the following two lines:
+<p><blockquote><pre>#define DB_DBM_HSEARCH    1
+#include &lt;db.h&gt;</pre></blockquote>
+<p>and recompile.  If the application attempts to load against a dbm library
+(e.g., <b>-ldbm</b>), remove the library from the load line.
+<p><b>Key</b> and <b>content</b> arguments are objects described by the
+<b>datum</b> typedef.  A <b>datum</b> specifies a string of
+<b>dsize</b> bytes pointed to by <b>dptr</b>.  Arbitrary binary data,
+as well as normal text strings, is allowed.
+<h3>Dbm Functions</h3>
+<p>Before a database can be accessed, it must be opened by dbminit.
+This will open and/or create the database <b>file</b>.db.  If created,
+the database file is created read/write by owner only (as described in
+<b>chmod</b>(2) and modified by the process' umask value at the time
+of creation (see <b>umask</b>(2)).  The group ownership of created
+files is based on the system and directory defaults, and is not further
+specified by Berkeley DB.
+<p>A database may be closed, and any held resources released, by calling
+dbmclose.
+<p>Once open, the data stored under a key is accessed by fetch and
+data is placed under a key by store.  A key (and its associated
+contents) is deleted by delete.  A linear pass through all keys
+in a database may be made, in an (apparently) random order, by use of
+firstkey and nextkey.  The firstkey function will return
+the first key in the database.  The nextkey function will return the next
+key in the database.
+<p>The following code will traverse the data base:
+<p><blockquote><pre>for (key = firstkey();
+    key.dptr != NULL; key = nextkey(key)) {
+	...
+}</pre></blockquote>
+<h3>Ndbm Functions</h3>
+<p>Before a database can be accessed, it must be opened by dbm_open.
+This will open and/or create the database file <b>file.db</b> depending
+on the flags parameter (see <b>open</b>(2)).  If created, the database
+file is created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by
+Berkeley DB.
+<p>Once open, the data stored under a key is accessed by dbm_fetch
+and data is placed under a key by dbm_store.  The <b>flags</b>
+field can be either <b>DBM_INSERT</b> or <b>DBM_REPLACE</b>.
+<b>DBM_INSERT</b> will only insert new entries into the database and will
+not change an existing entry with the same key.  <b>DBM_REPLACE</b> will
+replace an existing entry if it has the same key.  A key (and its
+associated contents) is deleted by dbm_delete.  A linear pass
+through all keys in a database may be made, in an (apparently) random
+order, by use of dbm_firstkey and dbm_nextkey.  The
+dbm_firstkey function will return the first key in the database.  The
+dbm_nextkey function will return the next key in the database.
+<p>The following code will traverse the data base:
+<p><blockquote><pre>for (key = dbm_firstkey(db);
+    key.dptr != NULL; key = dbm_nextkey(db)) {
+	...
+}</pre></blockquote>
+<h3>Compatibility Notes</h3>
+<p>The historic dbm library created two underlying database files,
+traditionally named <b>file.dir</b> and <b>file.pag</b>.  The Berkeley DB
+library creates a single database file named <b>file.db</b>.
+Applications that are aware of the underlying database file names may
+require additional source code modifications.
+<p>The historic dbminit interface required that the underlying
+<b>.dir</b> and <b>.pag</b> files already exist (empty databases were
+created by first manually creating zero-length <b>.dir</b> and
+<b>.pag</b> files).  Applications that expect to create databases using
+this method may require additional source code modifications.
+<p>The historic dbm_dirfno and dbm_pagfno macros are
+supported, but will return identical file descriptors as there is only a
+single underlying file used by the Berkeley DB hashing access method.
+Applications using both file descriptors for locking may require
+additional source code modifications.
+<p>If applications using the dbm interface exits without first
+closing the database, it may lose updates because the Berkeley DB library
+buffers writes to underlying databases.  Such applications will require
+additional source code modifications to work correctly with the Berkeley DB
+library.
+<h3>Dbm Diagnostics</h3>
+<p>The dbminit function returns -1 on failure, setting <b>errno</b>,
+and 0 on success.
+<p>The fetch function sets the <b>dptr</b> field of the returned
+<b>datum</b> to NULL on failure, setting <b>errno</b>,
+and returns a non-NULL <b>dptr</b> on success.
+<p>The store function returns -1 on failure, setting <b>errno</b>,
+and 0 on success.
+<p>The delete function returns -1 on failure, setting <b>errno</b>,
+and 0 on success.
+<p>The firstkey function sets the <b>dptr</b> field of the returned
+<b>datum</b> to NULL on failure, setting <b>errno</b>,
+and returns a non-NULL <b>dptr</b> on success.
+<p>The nextkey function sets the <b>dptr</b> field of the returned
+<b>datum</b> to NULL on failure, setting <b>errno</b>,
+and returns a non-NULL <b>dptr</b> on success.
+<h1>Errors</h1>
+<p>The dbminit, fetch, store, delete, firstkey and nextkey functions may fail
+and return a non-zero error for errors specified for other Berkeley DB and C
+library or system functions.
+<h3>Ndbm Diagnostics</h3>
+<p>The dbm_close function returns non-zero when an error has occurred reading or
+writing the database.
+<p>The dbm_close function resets the error condition on the named database.
+<p>The dbm_open function returns NULL on failure, setting <b>errno</b>,
+and 0 on success.
+<p>The dbm_fetch function sets the <b>dptr</b> field of the returned
+<b>datum</b> to NULL on failure, setting <b>errno</b>,
+and returns a non-NULL <b>dptr</b> on success.
+<p>The dbm_store function returns -1 on failure, setting <b>errno</b>,
+0 on success, and 1 if DBM_INSERT was set and the specified key already
+existed in the database.
+<p>The dbm_delete function returns -1 on failure, setting <b>errno</b>,
+and 0 on success.
+<p>The dbm_firstkey function sets the <b>dptr</b> field of the returned

+<h3>Key/Data Pairs</h3>
+<p>Storage and retrieval for the Berkeley DB access methods are based on key/data
+pairs.  Both key and data items are represented by the DBT data structure.
+(The name DBT is a mnemonic for <i>data base thang</i>, and was used
+because no one could think of a reasonable name that wasn't already in
+use somewhere else.) Key and data byte strings may reference strings of
+zero length up to strings of essentially unlimited length.  See
+<a href="../ref/program/dbsizes.html">Database limits</a> for more
+information.
+<p><blockquote><pre>typedef struct {
+	void *data;
+	u_int32_t size;
+	u_int32_t ulen;
+	u_int32_t dlen;
+	u_int32_t doff;
+	u_int32_t flags;
+} DBT;</pre></blockquote>
+<p>In order to ensure compatibility with future releases of Berkeley DB, all fields
+of the DBT structure that are not explicitly set should be initialized to
+0 before the first time the structure is used.  Do this by declaring the
+structure external or static, or by calling the C library routine
+<b>bzero</b>(3) or <b>memset</b>(3).
+<p>By default, the <b>flags</b> structure element is expected to be 0.  In
+this default case, when the application is providing Berkeley DB a key or data
+item to store into the database, Berkeley DB expects the <b>data</b> structure
+element to point to a byte string of <b>size</b> bytes.  When returning
+a key/data item to the application, Berkeley DB will store into the <b>data</b>
+structure element a pointer to a byte string of <b>size</b> bytes, and
+the memory referenced by the pointer will be allocated and managed by Berkeley DB.
+<p>The elements of the DBT structure are defined as follows:
+<p><dl compact>
+<p><dt>void *<a name="data">data</a>;<dd>A pointer to a byte string.
+<p><dt>u_int32_t <a name="size">size</a>;<dd>The length of <b>data</b>, in bytes.
+<p><dt>u_int32_t <a name="ulen">ulen</a>;<dd>The size of the user's buffer (referenced by <b>data</b>), in bytes.
+This location is not written by the Berkeley DB functions.
+<p>Note that applications can determine the length of a record by setting
+the <b>ulen</b> field to 0 and checking the return value in the
+<b>size</b> field.  See the DB_DBT_USERMEM flag for more information.
+<p><dt>u_int32_t <a name="dlen">dlen</a>;<dd>The length of the partial record being read or written by the application,
+in bytes.  See the DB_DBT_PARTIAL flag for more information.
+<p><dt>u_int32_t <a name="doff">doff</a>;<dd>The offset of the partial record being read or written by the application,
+in bytes.  See the DB_DBT_PARTIAL flag for more information.
+<p><dt>u_int32_t flags;<dd>
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_DBT_MALLOC">DB_DBT_MALLOC</a><dd>When this flag is set Berkeley DB will allocate memory for the returned key
+or data item (using <b>malloc</b>(3), or the user-specified malloc
+function) and return a pointer to it in the <b>data</b> field of the
+key or data DBT structure.  As any allocated memory becomes the
+responsibility of the calling application, the caller must be able to
+determine if memory was allocated.
+<p>It is an error to specify more than one of DB_DBT_MALLOC,
+DB_DBT_REALLOC and DB_DBT_USERMEM.
+<p><dt><a name="DB_DBT_REALLOC">DB_DBT_REALLOC</a><dd>When this flag is set Berkeley DB will allocate memory for the returned key
+or data item (using <b>realloc</b>(3), or the user-specified realloc
+function) and return a pointer to it in the <b>data</b> field of the
+key or data DBT structure.  As any allocated memory becomes the
+responsibility of the calling application, the caller must be able to
+determine if memory was allocated.
+<p>The difference between DB_DBT_MALLOC and DB_DBT_REALLOC
+is that the latter will call <b>realloc</b>(3) instead of
+<b>malloc</b>(3), so the allocated memory will be grown as necessary
+instead of the application doing repeated free/malloc calls.
+<p>It is an error to specify more than one of DB_DBT_MALLOC,
+DB_DBT_REALLOC and DB_DBT_USERMEM.
+<p><dt><a name="DB_DBT_USERMEM">DB_DBT_USERMEM</a><dd>The <b>data</b> field of the key or data structure must reference
+memory that is at least <b>ulen</b> bytes in length.  If the length of
+the requested item is less than or equal to that number of bytes, the
+item is copied into the memory referenced by the <b>data</b> field.
+Otherwise, the <b>size</b> field is set to the length needed for the
+requested item, and the error ENOMEM is returned.
+<p>It is an error to specify more than one of DB_DBT_MALLOC,
+DB_DBT_REALLOC and DB_DBT_USERMEM.
+<p><dt><a name="DB_DBT_PARTIAL">DB_DBT_PARTIAL</a><dd>Do partial retrieval or storage of an item.  If the calling application
+is doing a get, the <b>dlen</b> bytes starting <b>doff</b> bytes from
+the beginning of the retrieved data record are returned as if they
+comprised the entire record.  If any or all of the specified bytes do
+not exist in the record, the get is successful and the existing bytes
+or nul bytes are returned.
+<p>For example, if the data portion of a retrieved record was 100 bytes,
+and a partial retrieval was done using a DBT having a <b>dlen</b>
+field of 20 and a <b>doff</b> field of 85, the get call would succeed,
+the <b>data</b> field would reference the last 15 bytes of the record,
+and the <b>size</b> field would be set to 15.
+<p>If the calling application is doing a put, the <b>dlen</b> bytes
+starting <b>doff</b> bytes from the beginning of the specified key's
+data record are replaced by the data specified by the <b>data</b>
+and <b>size</b> structure elements.
+If <b>dlen</b> is smaller than <b>size</b>, the record will grow,
+and if <b>dlen</b> is larger than <b>size</b>, the record will shrink.
+If the specified bytes do not exist, the record will be extended using
+nul bytes as necessary, and the put call will succeed.
+<p>It is an error to attempt a partial put using the <a href="../api_c/db_put.html">DB-&gt;put</a> function
+in a database that supports duplicate records.
+Partial puts in databases supporting duplicate records must be done
+using a <a href="../api_c/dbc_put.html">DBcursor-&gt;c_put</a> function.
+<p>It is an error to attempt a partial put with differing <b>dlen</b> and
+<b>size</b> values in Queue or Recno databases with fixed-length records.
+<p>For example, if the data portion of a retrieved record was 100 bytes,
+and a partial put was done using a DBT having a <b>dlen</b> field of 20,
+a <b>doff</b> field of 85, and a <b>size</b> field of 30, the resulting
+record would be 115 bytes in length, where the last 30 bytes would be
+those specified by the put call.

+<h3>Retrieved key/data permanence</h3>
+<p>When using the non-cursor Berkeley DB calls to retrieve key/data items (e.g.,
+<a href="../api_c/db_get.html">DB-&gt;get</a>), the memory referenced by the pointer stored into the
+Dbt is only valid until the next call to Berkeley DB using the Db
+handle returned by <a href="../api_c/db_open.html">DB-&gt;open</a>.  (This includes <b>any</b> use of
+the returned Db handle, including by another thread of control
+within the process.  For this reason, when multiple threads are using the
+returned Db handle concurrently, one of the DB_DBT_MALLOC,
+DB_DBT_REALLOC or DB_DBT_USERMEM flags must be specified
+with any non-cursor Dbt used for key or data retrieval.)
+<p>When using the cursor Berkeley DB calls to retrieve key/data items (e.g.,
+<a href="../api_c/dbc_get.html">DBcursor-&gt;c_get</a>), the memory referenced by the pointer into the
+Dbt is only valid until the next call to Berkeley DB using the
+DBC handle returned by <a href="../api_c/db_cursor.html">DB-&gt;cursor</a>.
+        <a name="5"><!--meow--></a>    
+<h3>Data alignment</h3>
+<p>The Berkeley DB access methods provide no guarantees about key/data byte string
+alignment, and applications are responsible for arranging any necessary
+alignment.  The DB_DBT_MALLOC, DB_DBT_REALLOC and
+DB_DBT_USERMEM flags may be used to store returned items in memory
+of arbitrary alignment.
+        <a name="6"><!--meow--></a>    
+<h3>Logical Record Numbers</h3>
+<p>In all cases for the Queue and Recno access methods, and when calling the
+<a href="../api_c/db_get.html">DB-&gt;get</a> and <a href="../api_c/dbc_get.html">DBcursor-&gt;c_get</a> functions with the
+<a href="../api_c/db_get.html#DB_SET_RECNO">DB_SET_RECNO</a> flag specified, the <b>data</b> field of the key
+must be a pointer to a memory location of type <b>db_recno_t</b>, as
+typedef'd in the #include &lt;db.h&gt; include file.  This type is a 32-bit
+unsigned type, (which limits the number of logical records in a Queue or
+Recno database, and the maximum logical record which may be directly
+retrieved from a Btree database, to 4,294,967,296).  The <b>size</b>
+field of the key should be the size of that type, i.e., in the C
+programming language, <b>sizeof(db_recno_t)</b>.
+<p>Logical record numbers are 1-based, not 0-based, i.e., the first record
+in the database is record number 1.

+</pre></h3>
+<h1>Description</h1>
+<p>The DBENV-&gt;close function closes the Berkeley DB environment, freeing any
+allocated resources and closing any underlying subsystems.
+<p>Calling DBENV-&gt;close does not imply closing any databases that were
+opened in the environment.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>Where the environment was initialized with the <a href="../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a> flag,
+calling DBENV-&gt;close does not release any locks still held by the
+closing process, providing functionality for long-lived locks.
+Processes that wish to have all their locks
+released can do so by issuing the appropriate <a href="../api_c/lock_vec.html">lock_vec</a> call.
+<p>Where the environment was initialized with the <a href="../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a>
+flag, calling DBENV-&gt;close implies calls to <a href="../api_c/memp_fclose.html">memp_fclose</a> for
+any remaining open files in the memory pool that were returned to this
+process by calls to <a href="../api_c/memp_fopen.html">memp_fopen</a>.  It does not imply a call to
+<a href="../api_c/memp_fsync.html">memp_fsync</a> for those files.
+<p>Where the environment was initialized with the <a href="../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a> flag,
+calling DBENV-&gt;close aborts any uncommitted transactions.
+(Applications are should not depend on this behavior. If the process' has
+already closed a database handle which is necessary to abort an
+uncommitted transaction, the Berkeley DB environment must then require that
+recovery be run before further operations are done, since once a
+transaction exists that cannot be committed or aborted, no future
+checkpoint can ever succeed.)
+<p>In multi-threaded applications, only a single thread may call
+DBENV-&gt;close.
+<p>Once DBENV-&gt;close has been called, regardless of its return,
+the Berkeley DB environment handle may not be accessed again.
+<p>The DBENV-&gt;close function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The DBENV-&gt;close function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the DBENV-&gt;close function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The DBENV-&gt;open function is the interface for opening the Berkeley DB
+environment.  It provides a structure for creating a consistent
+environment for processes using one or more of the features of Berkeley DB.
+<p>The <b>db_home</b> argument to DBENV-&gt;open (and file name
+resolution in general) is described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p>The <b>flags</b> argument specifies the subsystems that are initialized
+and how the application's environment affects Berkeley DB file naming, among
+other things.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p>As there are a large number of flags that can be specified, they have been
+grouped together by functionality.  The first group of flags indicate
+which of the Berkeley DB subsystems should be initialized:
+<p><dl compact>
+<p><dt><a name="DB_JOINENV">DB_JOINENV</a><dd>Join an existing environment.  This option allows applications to
+join an existing environment without knowing which Berkeley DB subsystems
+the environment supports.
+<p><dt><a name="DB_INIT_CDB">DB_INIT_CDB</a><dd>Initialize locking for the <a href="../ref/cam/intro.html">Berkeley DB Concurrent Data Store</a>
+product.  In this mode, Berkeley DB provides multiple reader/single writer
+access.  The only other subsystem that should be specified with the
+DB_INIT_CDB flag is DB_INIT_MPOOL.
+<p>Access method calls are largely unchanged when using this flag, although
+any cursors through which update operations (e.g., <a href="../api_c/dbc_put.html">DBcursor-&gt;c_put</a>,

+multiple processes or threads are going to be reading and writing a Berkeley DB
+database, so that they do not interfere with each other.  If all threads
+are accessing the database(s) read-only, then locking is unnecessary.
+When the DB_INIT_LOCK flag is specified, it is usually necessary to run
+the deadlock detector, as well.  See <a href="../utility/db_deadlock.html">db_deadlock</a> and
+<a href="../api_c/lock_detect.html">lock_detect</a> for more information.
+<p><dt><a name="DB_INIT_LOG">DB_INIT_LOG</a><dd>Initialize the logging subsystem.  This subsystem is used when recovery
+from application or system failure is necessary.
+<p>The log is stored in one or more files in the environment directory.
+Each file is named using the format <i>log.NNNNNNNNNN</i>, where
+<i>NNNNNNNNNN</i> is the sequence number of the file within the log.
+For further information, see
+<a href="../ref/log/limits.html">Log File Limits</a>.
+<p>If the log region is being created and log files are already present, the
+log files are reviewed and subsequent log writes are appended
+to the end of the log, rather than overwriting current log entries.
+<p><dt><a name="DB_INIT_MPOOL">DB_INIT_MPOOL</a><dd>Initialize the shared memory buffer pool subsystem.  This subsystem is
+used whenever the application is using any Berkeley DB access method.
+<p><dt><a name="DB_INIT_TXN">DB_INIT_TXN</a><dd>Initialize the transaction subsystem.  This subsystem is used when
+recovery and atomicity of multiple operations and recovery are important.
+The DB_INIT_TXN flag implies the DB_INIT_LOG flag.
+</dl>
+<p>The second group of flags govern what recovery, if any, is performed when
+the environment is initialized:
+<p><dl compact>
+<p><dt><a name="DB_RECOVER">DB_RECOVER</a><dd>Run normal recovery on this environment before opening it for normal use.
+If this flag is set, the DB_CREATE flag must also be set since the regions
+will be removed and recreated.
+<p><dt><a name="DB_RECOVER_FATAL">DB_RECOVER_FATAL</a><dd>Run catastrophic recovery on this environment before opening it for normal
+use.  If this flag is set, the DB_CREATE flag must also be set since the
+regions will be removed and recreated.
+</dl>
+<p>A standard part of the recovery process is to remove the existing Berkeley DB
+environment and create a new one in which to perform recovery.  If the
+thread of control performing recovery does not specify the correct region
+initialization information (e.g., the correct memory pool cache size),
+the result can be an application running in an environment with incorrect
+cache and other subsystem sizes.  For this reason, the thread of control
+performing recovery should either specify correct configuration
+information before calling the DBENV-&gt;open function, or it should remove
+the environment after recovery is completed, leaving creation of the
+correctly sized environment to a subsequent call to DBENV-&gt;open.
+<p>All Berkeley DB recovery processing must be single-threaded, that is, only a
+single thread of control may perform recovery or access a Berkeley DB
+environment while recovery is being performed.  As it is not an error to
+specify DB_RECOVER for an environment for which no recovery is
+required, it is reasonable programming practice for the thread of control
+responsible for performing recovery and creating the environment to always
+specify the DB_RECOVER flag during startup.
+<p>The DBENV-&gt;open function returns successfully if DB_RECOVER
+or DB_RECOVER_FATAL is specified and no log files exist, so it is
+necessary to ensure all necessary log files are present before running
+recovery.  For further information, consult <a href="../utility/db_archive.html">db_archive</a> and
+<a href="../utility/db_recover.html">db_recover</a>.
+<p>The third group of flags govern file naming extensions in the environment:
+<p><dl compact>
+<!--$Id: m4.env_flags,v 10.9 2000/06/29 22:54:10 bostic Exp $-->
+<p><dt><a name="DB_USE_ENVIRON">DB_USE_ENVIRON</a><dd>The Berkeley DB process' environment may be permitted to specify information to
+be used when naming files; see <a href="../ref/env/naming.html">Berkeley DB

+naming for all users only if the DB_USE_ENVIRON flag is set.
+<p><dt><a name="DB_USE_ENVIRON_ROOT">DB_USE_ENVIRON_ROOT</a><dd>The Berkeley DB process' environment may be permitted to specify information to

+environment information will be used for file naming only for users with
+appropriate permissions (e.g., on UNIX systems, users with a user-ID of 0).
+</dl>
+<p>Finally, there are a few additional, unrelated flags:
+<p><dl compact>
+<p><dt><a name="DB_CREATE">DB_CREATE</a><dd>Cause Berkeley DB subsystems to create any underlying files, as necessary.
+<p><dt><a name="DB_LOCKDOWN">DB_LOCKDOWN</a><dd>Lock shared Berkeley DB environment files and memory mapped databases into memory.
+<p><dt><a name="DB_PRIVATE">DB_PRIVATE</a><dd>Specify that the environment will only be accessed by a single process
+(although that process may be multi-threaded).  This flag has two effects
+on the Berkeley DB environment.  First, all underlying data structures are
+allocated from per-process memory instead of from shared memory that is
+potentially accessible to more than a single process.  Second, mutexes
+are only configured to work between threads.
+<p>This flag should not be specified if more than a single process is
+accessing the environment, as it is likely to cause database corruption
+and unpredictable behavior, e.g., if both a server application and the
+Berkeley DB utility <a href="../utility/db_stat.html">db_stat</a> will access the environment, the
+DB_PRIVATE flag should not be specified.
+<p><dt><a name="DB_SYSTEM_MEM">DB_SYSTEM_MEM</a><dd>Allocate memory from system shared memory instead of from memory backed
+by the filesystem.  See <a href="../ref/env/region.html">Shared Memory

+<p><dt><a name="DB_THREAD">DB_THREAD</a><dd>Cause the DB_ENV handle returned by DBENV-&gt;open to be
+<i>free-threaded</i>, that is, useable by multiple threads within a
+single address space.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by Berkeley DB
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>The DBENV-&gt;open function returns a non-zero error value on failure and 0 on success.
+<h1>Environment Variables</h1>
+<p><dl compact>
+<p><dt>DB_HOME<dd>The environment variable <b>DB_HOME</b> may be used as the path of
+the database home as described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+</dl>
+<h1>Errors</h1>
+<p>The DBENV-&gt;open function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EAGAIN<dd>The shared memory region was locked and (repeatedly) unavailable.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.

+<h3><pre>
+#include &lt;db.h&gt;
+<p>
+int
+DBENV-&gt;remove(DB_ENV *, char *db_home, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The DBENV-&gt;remove function destroys a Berkeley DB environment, if it is not
+currently in use.  The environment regions, including any backing files,
+are removed.  Any log or database files and the environment directory are
+not removed.
+<p>The <b>db_home</b> argument to DBENV-&gt;remove is described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p>If there are processes that have called <a href="../api_c/env_open.html">DBENV-&gt;open</a> without
+calling <a href="../api_c/env_close.html">DBENV-&gt;close</a> (i.e., there are processes currently using
+the environment), DBENV-&gt;remove will fail without further action,
+unless the <a href="../api_c/env_remove.html#DB_FORCE">DB_FORCE</a> flag is set, in which case
+DBENV-&gt;remove will attempt to remove the environment regardless
+of any processes still using it.
+<p>The result of attempting to forcibly destroy the environment when it is
+in use is unspecified.  Processes using an environment often maintain open
+file descriptors for shared regions within it.  On UNIX systems, the
+environment removal will usually succeed and processes that have already
+joined the region will continue to run in that region without change,
+however processes attempting to join the environment will either fail or
+create new regions.  On other systems (e.g., Windows/NT), where the
+<b>unlink</b>(2) system call will fail if any process has an open
+file descriptor for the file, the region removal will fail.
+<p>Calling DBENV-&gt;remove should not be necessary for most applications,
+as the Berkeley DB environment is cleaned up as part of normal database recovery
+procedures, however, applications may wish to call DBENV-&gt;remove
+as part of application shutdown to free up system resources.
+Specifically, when the <a href="../api_c/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag was specified to
+<a href="../api_c/env_open.html">DBENV-&gt;open</a>, it may be useful to call DBENV-&gt;remove in order
+to release system shared memory segments that have been allocated.
+<p>In the case of catastrophic or system failure, database recovery must be
+performed (see <a href="../utility/db_recover.html">db_recover</a>), or the <a href="../api_c/env_open.html#DB_RECOVER">DB_RECOVER</a> and
+<a href="../api_c/env_open.html#DB_RECOVER_FATAL">DB_RECOVER_FATAL</a> flags to <a href="../api_c/env_open.html">DBENV-&gt;open</a> must be specified
+when the environment is re-opened.  Alternatively, if recovery is not
+required because no database state is maintained across failures, and
+the <a href="../api_c/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag was not specified when the environment
+was created, it is possible to clean up an environment by removing all
+of the files in the environment directory that begin with the string
+prefix "__db", as no backing files are created in any other directory.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_FORCE">DB_FORCE</a><dd>If the <a href="../api_c/env_remove.html#DB_FORCE">DB_FORCE</a> flag is set, the environment is removed regardless
+of any processes that may still using it, and, no locks are acquired
+during this process.  (Generally, the <a href="../api_c/env_remove.html#DB_FORCE">DB_FORCE</a> flag is only
+specified when applications were unable to shut down cleanly, and there
+is a risk that an application may have died holding a Berkeley DB lock.)

+<h1>Description</h1>
+<p>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.  For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>The DBENV-&gt;set_cachesize interface may only be used to configure Berkeley DB before
+the <a href="../api_c/env_open.html">DBENV-&gt;open</a> interface is called.
+<p>The DBENV-&gt;set_cachesize function returns a non-zero error value on failure and 0 on success.
+<p>The database environment's cache size may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_cachesize", one or more whitespace characters,
+and the three arguments specified to this interface, separated by whitespace
+characters, for example, "set_cachesize 1 500 2".  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+method database files.  Paths specified to the <a href="../api_c/db_open.html">DB-&gt;open</a> function
+will be searched relative to this path.  Paths set using this interface
+are additive, and specifying more than one will result in each specified
+directory being searched for database files.  If any directories are
+specified, created database files will always be created in the first path
+specified.
+<p>If no database directories are specified, database files can only exist
+in the environment home directory.   See <a href="../ref/env/naming.html">Berkeley DB File Naming</a> for more information.
+<p>For the greatest degree of recoverability from system or application
+failure, database files and log files should be located on separate
+physical devices.
+<p>The DBENV-&gt;set_data_dir interface may only be used to configure Berkeley DB before
+the <a href="../api_c/env_open.html">DBENV-&gt;open</a> interface is called.
+<p>The DBENV-&gt;set_data_dir function returns a non-zero error value on failure and 0 on success.
+<p>The database environment's data directory may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_data_dir", one or more whitespace characters,
+and the directory name.  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done

+operation that has been completed, specified as an integer value between
+0 and 100.  It is up to the callback function to display this
+information in an appropriate manner.

+<p>Log information is stored in-memory until the storage space fills up
+or transaction commit forces the information to be flushed to stable
+storage.  In the presence of long-running transactions or transactions
+producing large amounts of data, larger buffer sizes can increase
+throughput.
+<p>The DBENV-&gt;set_lg_bsize interface may only be used to configure Berkeley DB before

+<p>The DBENV-&gt;set_lg_bsize function returns a non-zero error value on failure and 0 on success.
+<p>The database environment's log buffer size may also be set using the environment's

+<h1>Description</h1>
+<p>Errors can occur in the Berkeley DB library where the only solution is to shut

+to write log records to disk because there is insufficient disk space.)
+In these cases, the value <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is returned by Berkeley DB.
+<p>In these cases, it is also often simpler to shut down the application when
+such errors occur rather than attempting to gracefully return up the stack.
+The DBENV-&gt;set_paniccall function is used to specify a function to be called when
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is about to be returned from a Berkeley DB method.  When
+called, the <b>dbenv</b> argument will be a reference to the current
+environment, and the <b>errval</b> argument is the error value that would
+have been returned to the calling function.
+<p>The DBENV-&gt;set_paniccall interface may be used to configure Berkeley DB at any time
+during the life of the application.
+<p>The DBENV-&gt;set_paniccall function returns a non-zero error value on failure and 0 on success.

+<h1>Description</h1>
+<p>Page-fault shared regions into memory when initially creating or joining
+a Berkeley DB environment.  In some applications, the expense of page-faulting
+the shared memory regions can affect performance, e.g., when the
+page-fault occurs while holding a lock, other lock requests can convoy
+and overall throughput may decrease.  Setting <b>region_init</b> to a
+non-zero value specifies that shared regions be read or written, as
+appropriate, when the region is joined by the application.  This forces
+the underlying virtual memory and file systems to instantiate both the
+necessary memory and the necessary disk space.  This can also avoid
+out-of-disk space failures later on.
+<p>The db_env_set_region_init interface affects the entire application, not a single
+database or database environment.
+<p>While the db_env_set_region_init interface may be used to configure Berkeley DB at any time

+<p>The db_env_set_region_init function returns a non-zero error value on failure and 0 on success.
+<p>The database environment's initial behavior with respect to shared memory regions may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_region_init", one or more whitespace characters,
+and the string "1".  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+<p>The <b>cl_timeout</b> argument specifies the number of seconds the client
+should wait for results to come back from the server.  Once the timeout
+has expired on any communication with the server, DB_NOSERVER will
+be returned.  If this value is zero, a default timeout is used.
+<p>The <b>sv_timeout</b> argument specifies the number of seconds the server
+should allow a client connection to remain idle before assuming that
+client is gone.  Once that timeout has been reached, the server releases
+all resources associated with that client connection.  Subsequent attempts
+by that client to communicate with the server result in
+DB_NOSERVER_ID indicating that an invalid identifier has been
+given to the server.  This value can be considered a hint to the server.
+The server may alter this value based on its own policies or allowed
+values.  If this value is zero, a default timeout is used.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>When the DBENV-&gt;set_server function has been called, any subsequent calls
+to Berkeley DB library interfaces may return either <a name="DB_NOSERVER">DB_NOSERVER</a> or
+<a name="DB_NOSERVER_ID">DB_NOSERVER_ID</a>.

+</pre></h3>
+<h1>Description</h1>
+<p>Specify a base segment ID for Berkeley DB environment shared memory regions
+created in system memory on VxWorks or systems supporting X/Open-style
+shared memory interfaces, e.g., UNIX systems supporting
+<b>shmget</b>(2) and related System V IPC interfaces.
+<p>This base segment ID will be used when Berkeley DB shared memory regions are
+first created.  It will be incremented a small integer value each time
+a new shared memory region is created, that is, if the base ID is 35,
+the first shared memory region created will have a segment ID of 35 and
+the next one a segment ID between 36 and 40 or so.  A Berkeley DB environment
+always creates a master shared memory region, plus an additional shared
+memory region for each of the subsystems supported by the environment
+(locking, logging, memory pool and transaction), plus an additional
+shared memory region for each additional memory pool cache that is
+supported.  Already existing regions with the same segment IDs will be
+removed.  See <a href="../ref/env/region.html">Shared Memory Regions</a>
+for more information.
+<p>The intent behind this interface is two-fold: without it, applications
+have no way to ensure that two Berkeley DB applications don't attempt to use
+the same segment IDs when creating different Berkeley DB environments.  In
+addition, by using the same segment IDs each time the environment is
+created, previously created segments will be removed, and the set of
+segments on the system will not grow without bound.
+<p>The DBENV-&gt;set_shm_key interface may only be used to configure Berkeley DB before
+the <a href="../api_c/env_open.html">DBENV-&gt;open</a> interface is called.
+<p>The DBENV-&gt;set_shm_key function returns a non-zero error value on failure and 0 on success.
+<p>The database environment's base segment ID may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_shm_key", one or more whitespace characters,
+and the ID.  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+<h1>Description</h1>
+<p>The hsearch interface to the Berkeley DB library is intended to
+provide a high-performance implementation and source code compatibility
+for applications written to the historic hsearch interface.
+It is not recommended for any other purpose.
+<p>To compile hsearch applications, replace the application's
+<b>#include</b> of the hsearch include
+file (e.g., <b>#include &lt;search.h&gt;</b>)
+with the following two lines:
+<p><blockquote><pre>
+#define DB_DBM_HSEARCH    1
+#include &lt;db.h&gt;</pre></blockquote>
+<p>and recompile.
+<p>The hcreate function creates an in-memory database.  The
+<b>nelem</b> argument is an estimation of the maximum number of key/data
+pairs that will be stored in the database.
+<p>The <b>hdestroy</b> function discards the database.
+<p>Database elements are structures of type <b>ENTRY</b>, which contain at
+least two fields: <b>key</b> and <b>data</b>.  The field <b>key</b> is
+declared to be of type <b>char *</b> and is the key used for storage
+and retrieval.  The field <b>data</b> is declared to be of type
+<b>void *</b> and is its associated data.
+<p>The hsearch function retrieves key/data pairs from, and stores
+key/data pairs into the database.
+<p>The <b>action</b> argument must be set to one of two values:
+<p><dl compact>
+<p><dt>ENTER<dd>If the key does not already appear in the database,
+insert the key/data pair into the database.
+If the key already appears in the database,
+return a reference to an <b>ENTRY</b>
+structure referencing the existing key and its associated data element.
+<p><dt>FIND<dd>Retrieve the specified key/data pair from the database.
+</dl>
+<h3>Compatibility Notes</h3>
+<p>Historically, hsearch required applications to maintain the keys
+and data in the application's memory for as long as the <b>hsearch</b>
+database existed.  As Berkeley DB handles key and data management internally,
+there is no requirement that applications maintain local copies of key
+and data items, although the only effect of doing so should be the
+allocation of additional memory.
+<h3>Hsearch Diagnostics</h3>
+<p>The <b>hcreate</b> function returns 0 on failure, setting <b>errno</b>
+and non-zero on success.
+<p>The <b>hsearch</b> function returns a pointer to an ENTRY structure on
+success, and NULL, setting <b>errno</b>, if the <b>action</b>
+specified was FIND and the item did not appear in the database.
+<h1>Errors</h1>
+<p>The hcreate function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the hcreate function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The lock_detect function runs one iteration of the deadlock detector.
+The deadlock detector traverses the lock table, and for each deadlock
+it finds, marks one of the participating transactions for abort.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_LOCK_CONFLICT">DB_LOCK_CONFLICT</a><dd>Only run the deadlock detector if a lock conflict has occurred since
+the last time that the deadlock detector was run.
+</dl>
+<p>The <b>atype</b> parameter specifies which transaction to abort in the
+case of deadlock.  It must be set to one of possible arguments listed for
+the <a href="../api_c/env_set_lk_detect.html">DBENV-&gt;set_lk_detect</a> interface.
+<p>If the <b>aborted</b> parameter is non-NULL, the memory location it
+references will be set to the number of transactions aborted by the
+lock_detect function.
+<p>The lock_detect function is the underlying function used by the <a href="../utility/db_deadlock.html">db_deadlock</a> utility.
+See the <a href="../utility/db_deadlock.html">db_deadlock</a> utility source code for an example of using lock_detect
+in a IEEE/ANSI Std 1003.1 (POSIX) environment.
+<p>The lock_detect function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The lock_detect function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the lock_detect function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The lock_get function acquires a lock from the lock table, returning
+information about it in
+the <b>lock</b> argument.
+<p>The <b>locker</b> argument specified to lock_get is an unsigned
+32-bit integer quantity.  It represents the entity requesting or releasing

+<p><dl compact>
+<p><dt><a name="DB_LOCK_NOWAIT">DB_LOCK_NOWAIT</a><dd>If a lock cannot be granted because the requested lock conflicts with an
+existing lock, return immediately instead of waiting for the lock to
+become available.
+</dl>
+<p>The <b>obj</b> argument is an untyped byte string that specifies the
+object to be locked or released.
+<p>The <b>mode</b> argument is an index into the environment's lock conflict
+array.  See <a href="../api_c/env_set_lk_conflicts.html">DBENV-&gt;set_lk_conflicts</a> and
+<a href="../ref/lock/stdmode.html">Standard Lock Modes</a>
+for a description of that array.

+<p><dt><a name="DB_LOCK_NOTGRANTED">DB_LOCK_NOTGRANTED</a><dd>A lock was requested that could not be immediately granted and the
+<b>flags</b> parameter was set to DB_LOCK_NOWAIT.
+</dl>
+<p>Otherwise, the lock_get function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The lock_get function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>DB_LOCK_DEADLOCK<dd>The operation was selected to resolve a deadlock.

+<p><dl compact>
+<p><dt>ENOMEM<dd>The maximum number of locks has been reached.
+</dl>
+<p>The lock_get function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the lock_get function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+from the lock table.  The lock_vec function is intended to support
+acquisition or trading of multiple locks under one lock table semaphore,
+as is needed for lock coupling or in multigranularity locking for lock
+escalation.
+<p>The <b>locker</b> argument specified to lock_vec is an unsigned
+32-bit integer quantity.  It represents the entity requesting or releasing
+the lock.
+<p>The <b>flags</b> value must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_LOCK_NOWAIT">DB_LOCK_NOWAIT</a><dd>If a lock cannot be immediately granted because the requested lock
+conflicts with an existing lock, return instead of waiting for the lock
+to become available.
+</dl>
+<p>The <b>list</b> array provided to lock_vec is typedef'd as
+DB_LOCKREQ.  A DB_LOCKREQ structure has at least the following fields,
+which must be initialized before calling lock_vec:
+<p><dl compact>
+<p><dt>lockop_t <a name="op">op</a>;<dd>The operation to be performed, which must be set to one of the
+following values:
+<p><dl compact>
+<p><dt><a name="DB_LOCK_GET">DB_LOCK_GET</a><dd>Get a lock, as defined by the values of <b>locker</b>, <b>obj</b>,
+and <b>mode</b>.  Upon return from lock_vec, if the
+<b>lock</b> field is non-NULL, a reference to the acquired lock is
+stored there.  (This reference is invalidated by any call to
+lock_vec or <a href="../api_c/lock_put.html">lock_put</a> that releases the lock.)
+<p><dt><a name="DB_LOCK_PUT">DB_LOCK_PUT</a><dd>The lock referenced by the contents of the <b>lock</b> field is released.
+<p><dt><a name="DB_LOCK_PUT_ALL">DB_LOCK_PUT_ALL</a><dd>All locks held by the <b>locker</b> are released.  (Any locks acquired
+as a part of the current call to lock_vec that appear after the
+DB_LOCK_PUT_ALL entry are not considered for this
+operation).
+<p><dt><a name="DB_LOCK_PUT_OBJ">DB_LOCK_PUT_OBJ</a><dd>All locks held on the object <b>obj</b> are released.  The <b>mode</b>
+and <b>locker</b> parameters are ignored.  Note that any locks acquired
+as a part of the current call to lock_vec that occur before the
+DB_LOCK_PUT_OBJ will also be released; those acquired afterwards
+will not be released.
+</dl>
+<p><dt>const DBT <a name="obj">obj</a>;<dd>An untyped byte string that specifies the object to be locked or released.
+<p><dt>const lockmode_t <a name="mode">mode</a>;<dd>The lock mode, used as an index into the environment's lock conflict array.
+See <a href="../api_c/env_set_lk_conflicts.html">DBENV-&gt;set_lk_conflicts</a> and <a href="../ref/lock/stdmode.html">Standard Lock Modes</a> for a description of that array.
+<p><dt>DB_LOCK <a name="lock">lock</a>;<dd>A lock reference.
+</dl>
+<p>The <b>nlist</b> argument specifies the number of elements in the
+<b>list</b> array.
+<p>If any of the requested locks cannot be acquired, or any of the locks to
+be released cannot be released, the operations before the failing
+operation are guaranteed to have completed successfully, and
+lock_vec returns a non-zero value.  In addition, if <b>elistp</b>
+is not NULL, it is set to point to the DB_LOCKREQ entry that was being
+processed when the error occurred.
+<p>The lock_vec function may
+return
+one of the following values:
+<p><dl compact>
+<p><dt><a name="DB_LOCK_NOTGRANTED">DB_LOCK_NOTGRANTED</a><dd>A lock was requested that could not be immediately granted and the
+<b>flag</b> parameter was set to DB_LOCK_NOWAIT.  In this case, if
+non-NULL, <b>elistp</b> identifies the request that was not granted.
+</dl>
+<p>Otherwise, the lock_vec function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The lock_vec function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>DB_LOCK_DEADLOCK<dd>The operation was selected to resolve a deadlock.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+</dl>
+<p><dl compact>
+<p><dt>ENOMEM<dd>The maximum number of locks has been reached.
+</dl>
+<p>The lock_vec function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the lock_vec function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h3><pre>
+#include &lt;db.h&gt;
+<p>
+int
+log_archive(DB_ENV *env, char *(*listp)[],
+    u_int32_t flags, void *(*db_malloc)(size_t));
+</pre></h3>
+<h1>Description</h1>
+<p>The log_archive function
+creates a NULL-terminated array of log or database file names and copies
+a pointer to them into the user-specified memory location <b>listp</b>.
+<p>By default, log_archive returns the names of all of the log files
+that are no longer in use (e.g., no longer involved in active transactions),
+and that may safely be archived for catastrophic recovery and then removed
+from the system.  If there were no file names to return, the memory location
+referenced by <b>listp</b> will be set to NULL.
+<p>Arrays of log file names are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_ARCH_ABS">DB_ARCH_ABS</a><dd>All pathnames are returned as absolute pathnames,
+instead of relative to the database home directory.
+<p><dt><a name="DB_ARCH_DATA">DB_ARCH_DATA</a><dd>Return the database files that need to be archived in order to recover
+the database from catastrophic failure.  If any of the database files
+have not been accessed during the lifetime of the current log files,
+log_archive will not include them in this list.  It is also
+possible that some of the files referenced in the log have since been
+deleted from the system.
+<p><dt><a name="DB_ARCH_LOG">DB_ARCH_LOG</a><dd>Return all the log file names regardless of whether or not they are in
+use.
+</dl>
+<p>The DB_ARCH_DATA and DB_ARCH_LOG flags are mutually
+exclusive.
+<p>See the <a href="../utility/db_archive.html">db_archive</a> manual page for more information on database
+archival procedures.
+<p>The log_archive function is the underlying function used by the <a href="../utility/db_archive.html">db_archive</a> utility.
+See the <a href="../utility/db_archive.html">db_archive</a> utility source code for an example of using log_archive
+in a IEEE/ANSI Std 1003.1 (POSIX) environment.
+<p>The log_archive function returns a non-zero error value on failure and 0 on success.
+<h1>Bugs</h1>
+<p>In a threaded application (i.e., one where the environment was created
+with the DB_THREAD flag specified), calling log_archive with the
+DB_ARCH_DATA flag will fail, returning EINVAL.  To work around this
+problem, re-open the log explicitly without specifying DB_THREAD.  This
+restriction is expected to be removed in a future version of Berkeley DB.
+<h1>Errors</h1>
+<p>The log_archive function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The log was corrupted.
+</dl>
+<p>The log_archive function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the log_archive function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+that all records with <a href="../api_c/db_lsn.html">DB_LSN</a> values less than or equal to the
+one being put are on disk before this function returns (this function
+is most often used for a transaction commit, see <a href="../api_c/txn_commit.html">txn_commit</a> for
+more information).
+<p>The caller is responsible for providing any necessary structure to
+<b>data</b>.  (For example, in a write-ahead logging protocol, the
+application must understand what part of <b>data</b> is an operation
+code, what part is redo information, and what part is undo information.
+In addition, most transaction managers will store in <b>data</b> the
+<a href="../api_c/db_lsn.html">DB_LSN</a> of the previous log record for the same transaction, to
+support chaining back through the transaction's log records during
+undo.)

+<p>The log_put function returns a non-zero error value on failure and 0 on success.

+<p>The record to be logged is larger than the maximum log record.

+<p>The log_put function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.

+<p>In addition, if the <b>file</b> argument to <a href="../api_c/memp_fopen.html">memp_fopen</a> was NULL,
+any underlying files created for this DB_MPOOLFILE will be removed.
+<p>Once memp_fclose has been called, regardless of its return, the
+DB_MPOOLFILE handle may not be accessed again.
+<p>The memp_fclose function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The memp_fclose function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the memp_fclose function may fail and return

+    int mode, size_t pagesize, DB_MPOOL_FINFO *finfop,

+</pre></h3>
+<h1>Description</h1>
+<p>The memp_fopen function opens a file in the pool specified by the
+DB_ENV <b>env</b>, copying the DB_MPOOLFILE pointer
+representing it into the memory location referenced by <b>mpf</b>.
+<p>The <b>file</b> argument is the name of the file to be opened.
+If <b>file</b> is NULL, a private file is created that cannot be
+shared with any other process (although it may be shared with
+other threads).
+<p>The <b>flags</b> and <b>mode</b> arguments specify how files will be opened
+and/or created if they do not already exist.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_CREATE">DB_CREATE</a><dd>Create any underlying files, as necessary.  If the files do not already
+exist and the DB_CREATE flag is not specified, the call will fail.
+<p><dt><a name="DB_NOMMAP">DB_NOMMAP</a><dd>Always copy this file into the local cache instead of potentially mapping
+it into process memory (see the description of the
+<a href="../api_c/env_set_mp_mmapsize.html">DBENV-&gt;set_mp_mmapsize</a> function for further information).
+<p><dt><a name="DB_RDONLY">DB_RDONLY</a><dd>Open any underlying files for reading only.  Any attempt to write the file
+using the pool functions will fail, regardless of the actual permissions
+of the file.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by function memp_fopen
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>The <b>pagesize</b> argument is the size, in bytes, of the unit of transfer
+between the application and the pool, although it is not necessarily the
+unit of transfer between the pool and the source file.
+<p>Files opened in the pool may be further configured based on the
+<b>finfop</b> argument to memp_fopen (which is a pointer to a
+structure of type DB_MPOOL_FINFO).  No references to the <b>finfop</b>
+structure are maintained by Berkeley DB, so it may be discarded when the
+memp_fopen function returns.  In order to ensure compatibility
+with future releases of Berkeley DB, all fields of the DB_MPOOL_FINFO structure
+that are not explicitly set should be initialized to 0 before the first
+time the structure is used.  Do this by declaring the structure external
+or static, or by calling the C library routine <b>bzero</b>(3) or
+<b>memset</b>(3).
+<p>The fields of the DB_MPOOL_FINFO structure used by memp_fopen are
+described below.  If <b>finfop</b> is NULL or any of its fields are
+set to their default value, defaults appropriate for the system are used.
+<p><dl compact>
+<p><dt>int <a name="ftype">ftype</a>;<dd>The <b>ftype</b> field should be the same as a <b>ftype</b> argument
+previously specified to the <a href="../api_c/memp_register.html">memp_register</a> function, unless no
+input or output processing of the file's pages are necessary, in which
+case it should be 0.  (See the description of the <a href="../api_c/memp_register.html">memp_register</a>
+function for more information.)
+<p><dt>DBT *<a name="pgcookie">pgcookie</a>;<dd>The <b>pgcookie</b> field contains the byte string that is passed to the
+<b>pgin</b> and <b>pgout</b> functions for this file, if any.  If no
+<b>pgin</b> or <b>pgout</b> functions are specified, the
+<b>pgcookie</b> field should be NULL.  (See the description of the
+<a href="../api_c/memp_register.html">memp_register</a> function for more information.)
+<p><dt>u_int8_t *<a name="fileid">fileid</a>;<dd>The <b>fileid</b> field is a unique identifier for the file.  If the
+<b>fileid</b> field is non-NULL, it must reference a DB_FILE_ID_LEN
+length array of bytes that will be used to uniquely identify the file.
+<p>The mpool functions must be able to uniquely identify files in order that
+multiple processes wanting to share a file will correctly identify it in
+the pool.
+<p>On most UNIX/POSIX systems, the <b>fileid</b> field will not need to be
+set and the mpool functions will simply use the file's device and inode
+numbers for this purpose.  On Windows systems, the mpool functions use
+the values returned by GetFileInformationByHandle() by default -- these
+values are known to be constant between processes and over reboot in the
+case of NTFS (where they are the NTFS MFT indexes).
+<p>On other filesystems, (e.g., FAT or NFS) these default values are not
+necessarily unique between processes or across system reboots.
+<b>Applications wanting to maintain a shared memory buffer pool
+between processes or across system reboots, where the pool contains pages
+from files stored on such filesystems, must specify a unique file
+identifier to the memp_fopen call and each process opening or
+registering the file must provide the same unique identifier.</b>
+<p>This should not be necessary for most applications.  Specifically, it is
+not necessary if the memory pool is not shared between processes and is
+re-instantiated after each system reboot, or the application is using the
+Berkeley DB access methods instead of calling the pool functions explicitly, or
+the files in the memory pool are stored on filesystems where the default
+values as described above are invariant between process and across system
+reboots.
+<p><dt>int32_t <a name="lsn_offset">lsn_offset</a>;<dd>The <b>lsn_offset</b> field is the zero-based byte offset in the page of
+the page's log sequence number (LSN), or -1 if no LSN offset is specified.
+(See the description of the <a href="../api_c/memp_sync.html">memp_sync</a> function for more
+information.)
+<p><dt>u_int32_t <a name="clear_len">clear_len</a>;<dd>The <b>clear_len</b> field is the number of initial bytes in a page
+that should be set to zero when the page is created as a result of the
+DB_MPOOL_CREATE or DB_MPOOL_NEW flags being specified to <a href="../api_c/memp_fget.html">memp_fget</a>.
+If <b>finfop</b> is NULL or <b>clear_len</b> is 0, the entire page is
+cleared.
+</dl>
+<p>The memp_fopen function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The memp_fopen function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The file has already been entered into the pool, and the <b>pagesize</b>
+value is not the same as when the file was entered into the pool, or the

+<p>The DB_RDONLY flag was specified for an in-memory pool.

+<h1>Description</h1>
+<p>The memp_register function registers page-in and page-out
+functions for files of type <b>ftype</b> in the specified pool.
+<p>If the <b>pgin_fcn</b> function is non-NULL, it is called each time
+a page is read into the memory pool from a file of type <b>ftype</b>, or
+a page is created for a file of type <b>ftype</b> (see the
+DB_MPOOL_CREATE flag for the <a href="../api_c/memp_fget.html">memp_fget</a> function).
+<p>If the <b>pgout_fcn</b> function is non-NULL, it is called each time
+a page is written to a file of type <b>ftype</b>.
+<p>Both the <b>pgin_fcn</b> and <b>pgout_fcn</b> functions are called with
+a reference to the current environment, the page number, a pointer to the
+page being read or written, and any argument <b>pgcookie</b> that was
+specified to the <a href="../api_c/memp_fopen.html">memp_fopen</a> function when the file was opened.
+The <b>pgin_fcn</b> and <b>pgout_fcn</b> functions should return 0 on
+success, and an applicable non-zero <b>errno</b> value on failure, in
+which case the shared memory pool interface routine (and, by extension,
+any Berkeley DB library function) calling it will also fail, returning that
+<b>errno</b> value.
+<p>The purpose of the memp_register function is to support processing
+when pages are entered into, or flushed from, the pool.  A file type must
+be specified to make it possible for unrelated threads or processes, that
+are sharing a pool, to evict each other's pages from the pool.
+Applications should call memp_register, during initialization,
+for each type of file requiring input or output processing that will be
+sharing the underlying pool.  (No registry is necessary for the standard
+Berkeley DB access method types, as <a href="../api_c/db_open.html">DB-&gt;open</a> registers them
+separately.)
+<p>If a thread or process does not call memp_register for a file
+type, it is impossible for it to evict pages for any file requiring input
+or output processing from the pool.  For this reason,
+memp_register should always be called by each application sharing
+a pool for each type of file included in the pool, regardless of whether
+or not the application itself uses files of that type.
+<p>There are no standard values for <b>ftype</b>, <b>pgin_fcn</b>,
+<b>pgout_fcn</b> and <b>pgcookie</b>, except that the <b>ftype</b>
+value for a file must be a non-zero positive number, as negative numbers
+are reserved for internal use by the Berkeley DB library.  For this reason,
+applications sharing a pool must coordinate their values amongst
+themselves.
+<p>The memp_register function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The memp_register function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.

+reference, references inside the returned memory do not need to be
+individually freed.

+<h3><pre>
+#include &lt;db.h&gt;
+<p>
+int
+memp_sync(DB_ENV *env, DB_LSN *lsn);
+</pre></h3>
+<h1>Description</h1>
+<p>The memp_sync function ensures that any modified pages in the pool with
+log sequence numbers less than the <b>lsn</b> argument are written to
+disk.  If <b>lsn</b> is NULL all modified pages in the pool are
+flushed.
+<p>The primary purpose of the memp_sync function is to enable a
+transaction manager to ensure, as part of a checkpoint, that all pages
+modified by a certain time have been written to disk.  Pages in the pool
+that cannot be written back to disk immediately (e.g., that are currently
+pinned) are written to disk as soon as it is possible to do so.  The
+expected behavior of the Berkeley DB or other transaction subsystem is to call
+the memp_sync function and then, if the return indicates that some
+pages could not be written immediately, to wait briefly and retry again
+with the same log sequence number until the memp_sync function
+returns that all pages have been written.
+<p>To support the memp_sync functionality, it is necessary that the
+pool functions know the location of the log sequence number on the page
+for each file type.  This location should be specified when the file is
+opened using the <a href="../api_c/memp_fopen.html">memp_fopen</a> function.  It is not required that
+the log sequence number be aligned on the page in any way.
+<p>The memp_sync function returns a non-zero error value on failure, 0 on success, and returns <a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> if there were pages which need to be
+written but which memp_sync was unable to write immediately.
+In addition, if memp_sync returns success, the value of
+<b>lsn</b> will be overwritten with the largest log sequence number
+from any page which was written by memp_sync to satisfy this
+request.
+<h1>Errors</h1>
+<p>The memp_sync function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The memp_sync function was called without logging having been
+initialized in the environment.
+</dl>
+<p>The memp_sync function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the memp_sync function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+#include &lt;db.h&gt;
+<p>
+int
+memp_trickle(DB_ENV *env, int pct, int *nwrotep);
+</pre></h3>
+<h1>Description</h1>
+<p>The memp_trickle function ensures that at least <b>pct</b> percent of
+the pages in the shared memory pool are clean by writing dirty pages to
+their backing files.
+If the <b>nwrotep</b> argument is non-NULL, the number of pages that
+were written to reach the correct percentage is returned in the memory
+location it references.
+<p>The purpose of the memp_trickle function is to enable a memory
+pool manager to ensure that a page is always available for reading in new
+information without having to wait for a write.
+<p>The memp_trickle function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The memp_trickle function may fail and return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+</dl>
+<p>The memp_trickle function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the memp_trickle function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The Berkeley DB library requires the ability to determine if a file exists, and
+optionally, if it is a file of type directory.  The <b>func</b> argument
+must conform to the following interface:
+<p><blockquote><pre>int exists(const char *path, int *isdirp);</pre></blockquote>
+<p>The <b>path</b> argument is the pathname of the file to be checked.
+<p>If the <b>isdirp</b> argument is non-NULL, it must be set to non-0 if
+<b>path</b> is a directory, and 0 if <b>path</b> is not a directory.
+<p>The <b>func_exists</b> function must return the value of <b>errno</b> on
+failure and 0 on success.
+<p>The db_env_set_func_exists interface affects the entire application, not a single
+database or database environment.
+<p>While the db_env_set_func_exists interface may be used to configure Berkeley DB at any time
+during the life of the application, it should normally be called before
+making any calls to the <a href="../api_c/env_create.html">db_env_create</a> or <a href="../api_c/db_create.html">db_create</a> functions.
+<p>The db_env_set_func_exists interface may only be used to configure Berkeley DB before
+the <a href="../api_c/env_open.html">DBENV-&gt;open</a> interface is called.
+<p>The db_env_set_func_exists function returns a non-zero error value on failure and 0 on success.

+</pre></h3>
+<h1>Description</h1>
+<p>The Berkeley DB library requires the ability to map a file into memory and to
+create shared memory regions (which may or may not be backed by files).
+The <b>func_map</b> argument must conform to the following interface:
+<p><blockquote><pre>int map(char *path, size_t len,
+int is_region, int is_rdonly, void **addr);</pre></blockquote>
+<p>The <b>path</b> argument is the name of a file.
+<p>The <b>is_region</b> argument will be zero if the intention is to map a
+file into shared memory.  In this case, the <b>map</b> function must map
+the first <b>len</b> bytes of the file into memory and return a pointer
+to the mapped location in the memory location referenced by the argument
+<b>addr</b>.  The <b>is_rdonly</b> argument will be non-zero if the file
+is considered read-only by the caller.
+<p>The <b>is_region</b> argument will be non-zero if the memory is intended
+to be used as a shared memory region for synchronization between Berkeley DB
+threads/processes.  In this case, the returned memory may be of any kind
+(e.g., anonymous), but must be able to support semaphores.  In this case,
+the <b>path</b> argument may be ignored (although future <b>map</b>
+calls using the same <b>path</b> must return the same memory), and the
+<b>is_rdonly</b> argument will always be zero.
+<p>The <b>func_map</b> function must return the value of <b>errno</b> on
+failure and 0 on success.
+<p>The db_env_set_func_map interface affects the entire application, not a single
+database or database environment.
+<p>While the db_env_set_func_map interface may be used to configure Berkeley DB at any time
+during the life of the application, it should normally be called before
+making any calls to the <a href="../api_c/env_create.html">db_env_create</a> or <a href="../api_c/db_create.html">db_create</a> functions.
+<p>The db_env_set_func_map function returns a non-zero error value on failure and 0 on success.

+<h1>Description</h1>
+<p>The Berkeley DB library requires the ability to specify that a subsequent read
+from or write to a file will occur at a specific location in that file.
+The <b>func_seek</b> argument must conform to the following interface:
+<p><blockquote><pre>int seek(int fd, size_t pgsize, db_pgno_t pageno,
+u_int32_t relative, int rewind, int whence);</pre></blockquote>
+<p>The <b>fd</b> argument is an open file descriptor on the file.
+<p>The <b>seek</b> function must cause a subsequent read from or write to
+the file to occur at a byte offset specified by the calculation:
+<p><blockquote><pre>(pgsize * pageno) + relative</pre></blockquote>
+<p>If <b>rewind</b> is non-zero, the byte offset is treated as a backwards
+seek, not a forwards one.
+<p>The <b>whence</b> argument specifies where in the file the byte offset
+is relative to, as described by the IEEE/ANSI Std 1003.1 (POSIX) <b>lseek</b> system
+call.
+<p>The <b>func_seek</b> function must return the value of <b>errno</b> on
+failure and 0 on success.
+<p>The db_env_set_func_seek interface affects the entire application, not a single
+database or database environment.
+<p>While the db_env_set_func_seek interface may be used to configure Berkeley DB at any time
+during the life of the application, it should normally be called before
+making any calls to the <a href="../api_c/env_create.html">db_env_create</a> or <a href="../api_c/db_create.html">db_create</a> functions.
+<p>The db_env_set_func_seek function returns a non-zero error value on failure and 0 on success.

+<p>

+</pre></h3>
+<h1>Description</h1>
+<p>The Berkeley DB library requires the ability to yield the processor from the current
+thread of control to any other waiting threads of control.
+The <b>func_yield</b> argument must conform to the following interface:
+<p><blockquote><pre>int yield(void);</pre></blockquote>
+<p>The <b>func_yield</b> function must be able to cause the rescheduling
+all participants in the current Berkeley DB environment, whether threaded or
+not.  It may be incorrect to supply a thread <b>yield</b> function if
+more than a single process is operating in the Berkeley DB environment.  This
+is because many thread-yield functions will not allow other processes to
+run, and the contested lock may be held by another process, not by another
+thread.
+<p>If no <b>func_yield</b> function is specified, or if the <b>yield</b>
+function returns an error, the function specified by the
+<a href="../api_c/set_func_sleep.html">db_env_set_func_sleep</a> entry will be used instead or subsequently,
+i.e., if no <b>yield</b> function is specified, or it is possible for
+the <b>yield</b> function to fail, the <b>sleep</b> function
+<b>must</b> cause the processor to reschedule any waiting threads of
+control for execution.
+<p>The <b>func_yield</b> function must return the value of <b>errno</b> on
+failure and 0 on success.
+<p>The db_env_set_func_yield interface affects the entire application, not a single
+database or database environment.
+<p>While the db_env_set_func_yield interface may be used to configure Berkeley DB at any time
+during the life of the application, it should normally be called before
+making any calls to the <a href="../api_c/env_create.html">db_env_create</a> or <a href="../api_c/db_create.html">db_create</a> functions.
+<p>The db_env_set_func_yield function returns a non-zero error value on failure and 0 on success.

+<h1>Description</h1>
+<p>The txn_abort function causes an abnormal termination of the
+transaction.  The log is played backwards and any necessary recovery
+operations are initiated through the <b>recover</b> function specified
+to <a href="../api_c/env_open.html">DBENV-&gt;open</a>.  After the log processing is completed, all locks
+held by the transaction are released.  As is the case for
+<a href="../api_c/txn_commit.html">txn_commit</a>, applications that require strict two-phase locking
+should not explicitly release any locks.
+<p>In the case of nested transactions, aborting a parent transaction causes
+all children (unresolved or not) of the parent transaction to be aborted.
+<p>Once the txn_abort function returns, the DB_TXN handle may not
+be accessed again.
+<p>The txn_abort function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The txn_abort function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the txn_abort function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The txn_prepare function initiates the beginning of a two-phase commit.
+<p>In a distributed transaction environment, Berkeley DB can be used as a local
+transaction manager.  In this case, the distributed transaction manager
+must send <i>prepare</i> messages to each local manager.  The local
+manager must then issue a txn_prepare and await its successful
+return before responding to the distributed transaction manager.  Only
+after the distributed transaction manager receives successful responses
+from all of its <i>prepare</i> messages should it issue any
+<i>commit</i> messages.
+<p>In the case of nested transactions, preparing a parent transaction
+causes all unresolved children of the parent transaction to be prepared.
+<p>The txn_prepare function returns a non-zero error value on failure and 0 on success.
+<h1>Errors</h1>
+<p>The txn_prepare function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
+If a catastrophic error has occurred, the txn_prepare function may fail and return
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The txn_stat function
+creates a statistical structure and copies a pointer to it into a
+user-specified memory location.
+<p>Statistical structures are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The transaction region statistics are stored in a structure of type
+DB_TXN_STAT.  The following DB_TXN_STAT fields will be filled in:
+<p><dl compact>
+<dt><a href="../api_c/db_lsn.html">DB_LSN</a> st_last_ckp;<dd>The LSN of the last checkpoint.
+<dt><a href="../api_c/db_lsn.html">DB_LSN</a> st_pending_ckp;<dd>The LSN of any checkpoint that is currently in progress.  If
+<b>st_pending_ckp</b> is the same as <b>st_last_ckp</b> there
+is no checkpoint in progress.
+<dt>time_t st_time_ckp;<dd>The time the last completed checkpoint finished (as the number of seconds
+since the Epoch, returned by the IEEE/ANSI Std 1003.1 (POSIX) <b>time</b> interface).
+<dt>u_int32_t st_last_txnid;<dd>The last transaction ID allocated.
+<dt>u_int32_t st_maxtxns;<dd>The maximum number of active transactions possible.
+<dt>u_int32_t st_nactive;<dd>The number of transactions that are currently active.
+<dt>u_int32_t st_maxnactive;<dd>The maximum number of active transactions at any one time.
+<dt>u_int32_t st_nbegins;<dd>The number of transactions that have begun.
+<dt>u_int32_t st_naborts;<dd>The number of transactions that have aborted.
+<dt>u_int32_t st_ncommits;<dd>The number of transactions that have committed.
+<dt>u_int32_t st_regsize;<dd>The size of the region.
+<dt>u_int32_t st_region_wait;<dd>The number of times that a thread of control was forced to wait before
+obtaining the region lock.
+<dt>u_int32_t st_region_nowait;<dd>The number of times that a thread of control was able to obtain
+the region lock without waiting.
+<dt>DB_TXN_ACTIVE * st_txnarray;<dd>A pointer to an array of <b>st_nactive</b> DB_TXN_ACTIVE structures,
+describing the currently active transactions.  The following fields of
+the DB_TXN_ACTIVE structure will be filled in:
+<p><dl compact>
+<p><dt>u_int32_t txnid;<dd>The transaction ID as returned by <a href="../api_c/txn_begin.html">txn_begin</a>.

+<dt><a href="../api_c/db_lsn.html">DB_LSN</a> lsn;<dd>The log sequence number of the transaction-begin record.
+</dl>

+<h1>Description</h1>
+<p>This manual page describes the specific details of the Db class,
+which is the center of access method activity.
+<p>If no <b>dbenv</b> value is specified, the database is standalone, i.e.,
+it is not part of any Berkeley DB environment.
+<p>If a <b>dbenv</b> value is specified, the database is created within the
+specified Berkeley DB environment. The database access methods automatically
+make calls to the other subsystems in Berkeley DB based on the enclosing
+environment. For example, if the environment has been configured to use
+locking, then the access methods will automatically acquire the correct
+locks when reading and writing pages of the database.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_CXX_NO_EXCEPTIONS">DB_CXX_NO_EXCEPTIONS</a><dd>The Berkeley DB C++ API supports two different error behaviors.  By default,
+whenever an error occurs an exception is thrown that encapsulates the
+error information.  This generally allows for cleaner logic for
+transaction processing, as a try block can surround a single transaction.
+However, if DB_CXX_NO_EXCEPTIONS is specified, exceptions are not
+thrown, instead each individual function returns an error code.
+<p>If <b>dbenv</b> is not null, this flag is ignored and the error behavior
+of the specified environment is used instead.
+<p><dt><a name="DB_XA_CREATE">DB_XA_CREATE</a><dd>Instead of creating a standalone database, create a database intended to
+be accessed via applications running under a X/Open conformant Transaction
+Manager.  The database will be opened in the environment specified by the
+OPENINFO parameter of the GROUPS section of the ubbconfig file.  See the
+<a href="../ref/xa/intro.html">XA Resource Manager</a> chapter in the
+Reference Guide for more information.

+<h3><pre>
+#include &lt;db_cxx.h&gt;
+<p>
+int
+Db::close(u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The Db::close method flushes any cached database information to disk,
+closes any open cursors, frees any allocated resources, and closes any
+underlying files.  Since key/data pairs are cached in memory, failing to
+sync the file with the Db::close or <a href="../api_cxx/db_sync.html">Db::sync</a> method may result
+in inconsistent or lost information.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_NOSYNC">DB_NOSYNC</a><dd>Do not flush cached information to disk.
+<p>The <a href="../api_cxx/db_close.html#DB_NOSYNC">DB_NOSYNC</a> flag is a dangerous option.  It should only be set
+if the application is doing logging (with transactions) so that the
+database is recoverable after a system or application crash, or if the
+database is always generated from scratch after any system or application
+crash.
+<p><b>It is important to understand that flushing cached information to disk
+only minimizes the window of opportunity for corrupted data.</b>
+While unlikely, it is possible for database corruption to happen if a
+system or application crash occurs while writing data to the database.
+To ensure that database corruption never occurs, applications must either:
+use transactions and logging with automatic recovery, use logging and
+application-specific recovery, or edit a copy of the database,
+and, once all applications using the database have successfully called
+Db::close, atomically replace the original database with the
+updated copy.
+</dl>
+<p>When multiple threads are using the Berkeley DB handle concurrently, only a single
+thread may call the Db::close method.
+<p>Once Db::close has been called, regardless of its return, the
+<a href="../api_cxx/db_class.html">Db</a> handle may not be accessed again.
+        <a name="3"><!--meow--></a>    
+<p>The Db::close method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, 0 on success, and returns <a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> if the underlying database still has
+dirty pages in the cache.  (The only reason to return
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> is if another thread of control was writing pages
+in the underlying database file at the same time as the
+Db::close method was called.  For this reason, a return of
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> can normally be ignored, or, in cases where it is
+a possible return value, the <a href="../api_cxx/db_close.html#DB_NOSYNC">DB_NOSYNC</a> option should probably
+have been specified.)
+<p>The Db::close method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The Db::close method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db::close method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+<h1>Description</h1>
+<p>The Db::del method removes key/data pairs from the database.  The
+key/data pair associated with the specified <b>key</b> is discarded from
+the database.  In the presence of duplicate key values, all records
+associated with the designated key will be discarded.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_cxx/txn_begin.html">DbEnv::txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>The Db::del method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, 0 on success, and <a href="../ref/program/errorret.html#DB_NOTFOUND">DB_NOTFOUND</a> if the specified <b>key</b> did not exist in
+the file.
+<h1>Errors</h1>
+<p>The Db::del method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>DB_LOCK_DEADLOCK<dd>The operation was selected to resolve a deadlock.
+</dl>
+<p><dl compact>
+<p><dt>EACCES<dd>An attempt was made to modify a read-only database.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+</dl>
+<p>The Db::del method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db::del method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<h1>Description</h1>
+<p>The DbEnv::err, DbEnv::errx,  Db::err and
+Db::errx methods provide error messaging functionality for
+applications written using the Berkeley DB library.
+<p>The DbEnv::err method constructs an error message consisting of the
+following elements:
+<p><blockquote><p><dl compact>
+<p><dt>An optional prefix string<dd>If no error callback method has been set using the
+<a href="../api_cxx/env_set_errcall.html">DbEnv::set_errcall</a> method, any prefix string specified using the
+<a href="../api_cxx/env_set_errpfx.html">DbEnv::set_errpfx</a> method, followed by two separating characters: a colon
+and a &lt;space&gt; character.
+<p><dt>An optional printf-style message<dd>The supplied message <b>fmt</b>, if non-NULL, where the ANSI C X3.159-1989 (ANSI C)
+printf function specifies how subsequent arguments are converted for
+output.
+<p><dt>A separator<dd>Two separating characters: a colon and a &lt;space&gt; character.
+<p><dt>A standard error string<dd>The standard system or Berkeley DB library error string associated with the
+<b>error</b> value, as returned by the <a href="../api_cxx/env_strerror.html">DbEnv::strerror</a> method.
+</dl>
+</blockquote>
+<p>This constructed error message is then handled as follows:
+<p><blockquote>
+<p>If an error callback method has been set (see <a href="../api_cxx/db_set_errcall.html">Db::set_errcall</a>
+and <a href="../api_cxx/env_set_errcall.html">DbEnv::set_errcall</a>), that method is called with two
+arguments: any prefix string specified (see <a href="../api_cxx/db_set_errpfx.html">Db::set_errpfx</a> and
+<a href="../api_cxx/env_set_errpfx.html">DbEnv::set_errpfx</a>), and the error message.
+<p>If a C library FILE * has been set (see <a href="../api_cxx/db_set_errfile.html">Db::set_errfile</a> and
+<a href="../api_cxx/env_set_errfile.html">DbEnv::set_errfile</a>), the error message is written to that output
+stream.
+<p>If a C++ ostream has been set
+(see <a href="../api_cxx/env_set_error_stream.html">DbEnv::set_error_stream</a>), the error message is written to that
+stream.
+<p>If none of these output options has been configured, the error message
+is written to stderr, the standard error output stream.</blockquote>
+<p>The DbEnv::errx and Db::errx methods perform identically to the
+DbEnv::err and Db::err methods except that they do not append
+the final separator characters and standard error string to the error
+message.

+<h1>Description</h1>
+<p>The Db::get method retrieves key/data pairs from the database.  The
+address
+and length of the data associated with the specified <b>key</b> are
+returned in the structure referenced by <b>data</b>.
+<p>In the presence of duplicate key values, Db::get will return the
+first data item for the designated key.  Duplicates are sorted by insert
+order except where this order has been overridden by cursor operations.
+<b>Retrieval of duplicates requires the use of cursor operations.</b>
+See <a href="../api_cxx/dbc_get.html">Dbc::get</a> for details.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_cxx/txn_begin.html">DbEnv::txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_CONSUME">DB_CONSUME</a><dd>Return the record number and data from the available record closest to

+<p><dt><a name="DB_CONSUME_WAIT">DB_CONSUME_WAIT</a><dd>The DB_CONSUME_WAIT flag is the same as the DB_CONSUME
+flag except that if the Queue database is empty, the thread of control

+to be specified.
+<p><dt><a name="DB_GET_BOTH">DB_GET_BOTH</a><dd>Retrieve the key/data pair only if both the key and data match the

+Db::get method.
+<p>The <b>data</b> field of the specified <b>key</b>
+must be a pointer to a logical record number (i.e., a <b>db_recno_t</b>).
+This record number determines the record to be retrieved.
+<p>For DB_SET_RECNO to be specified, the underlying database must be
+of type Btree and it must have been created with the DB_RECNUM flag.

+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="DB_RMW">DB_RMW</a><dd>Acquire write locks instead of read locks when doing the retrieval.
+Setting this flag may decrease the likelihood of deadlock during a
+read-modify-write cycle by immediately acquiring the write lock during
+the read part of the cycle so that another thread of control acquiring
+a read lock for the same item, in its own read-modify-write cycle, will
+not result in deadlock.
+<p>As the Db::get interface will not hold locks across
+Berkeley DB interface calls in non-transactional environments, the
+<a href="../api_cxx/dbc_get.html#DB_RMW">DB_RMW</a> flag to the Db::get call is only meaningful in
+the presence of transactions.
+</dl>
+<p>If the database is a Queue or Recno database and the requested key exists,
+but was never explicitly created by the application or was later deleted,
+the Db::get method returns <a href="../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a>.
+<p>Otherwise, if the requested key is not in the database, the
+Db::get function returns <a href="../ref/program/errorret.html#DB_NOTFOUND">DB_NOTFOUND</a>.

+<p>
+int
+Db::join(Dbc **curslist, Dbc **dbcp, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The Db::join method creates a specialized cursor for use in performing
+joins on secondary indexes.  For information on how to organize your data
+to use this functionality, see <a href="../ref/am/join.html">Logical
+join</a>.
+<p>The <b>primary</b> argument contains the <a href="../api_cxx/db_class.html">Db</a> handle of the primary
+database, which is keyed by the data values found in entries in the
+<b>curslist</b>.
+<p>The <b>curslist</b> argument contains a NULL terminated array of cursors.
+Each cursor must have been initialized to reference the key on which the
+underlying database should be joined.  Typically, this initialization is done
+by a <a href="../api_cxx/dbc_get.html">Dbc::get</a> call with the <a href="../api_cxx/dbc_get.html#DB_SET">DB_SET</a> flag specified.  Once the
+cursors have been passed as part of a <b>curslist</b>, they should not
+be accessed or modified until the newly created join cursor has been closed,
+or else inconsistent results may be returned.
+<p>Joined values are retrieved by doing a sequential iteration over the first
+cursor in the <b>curslist</b> argument, and a nested iteration over each
+secondary cursor in the order they are specified in the <b>curslist</b>
+argument.  This requires database traversals to search for the current
+datum in all the cursors after the first.  For this reason, the best join
+performance normally results from sorting the cursors from the one that
+references the least number of data items to the one that references the
+most.  By default, Db::join does this sort on behalf of its caller.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_JOIN_NOSORT">DB_JOIN_NOSORT</a><dd>Do not sort the cursors based on the number of data items they reference.
+If the data are structured such that cursors with many data items also
+share many common elements, higher performance will result from listing
+those cursors before cursors with fewer data items, that is, a sort order
+other than the default.  The DB_JOIN_NOSORT flag permits
+applications to perform join optimization prior to calling Db::join.
+</dl>
+<p>A newly created cursor is returned in the memory location referenced by
+<b>dbcp</b> and has the standard cursor functions:
+<p><dl compact>
+<p><dt><a href="../api_cxx/dbc_get.html">Dbc::get</a><dd>Iterates over the values associated with the keys to which each item in
+<b>curslist</b> has been initialized.  Any data value which appears in
+all items specified by the <b>curslist</b> argument is then used as a
+key into the <b>primary</b>, and the key/data pair found in the
+<b>primary</b> is returned.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_JOIN_ITEM">DB_JOIN_ITEM</a><dd>Do not use the data value found in all of the cursors as a lookup
+key for the <b>primary</b>, but simply return it in the key parameter
+instead.  The data parameter is left unchanged.
+</dl>
+<p>In addition, the following flag may be set by bitwise inclusively <b>OR</b>'ing it into the
+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="DB_RMW">DB_RMW</a><dd>Acquire write locks instead of read locks when doing the retrieval.
+Setting this flag may decrease the likelihood of deadlock during a
+read-modify-write cycle by immediately acquiring the write lock during
+the read part of the cycle so that another thread of control acquiring
+a read lock for the same item, in its own read-modify-write cycle, will
+not result in deadlock.
+</dl>
+<p><dt><a href="../api_cxx/dbc_put.html">Dbc::put</a><dd>Returns EINVAL.
+<p><dt><a href="../api_cxx/dbc_del.html">Dbc::del</a><dd>Returns EINVAL.
+<p><dt><a href="../api_cxx/dbc_close.html">Dbc::close</a><dd>Close the returned cursor and release all resources.  (Closing the cursors
+in <b>curslist</b> is the responsibility of the caller.)
+</dl>
+<p>For the returned join cursor to be used in a transaction protected manner,
+the cursors listed in <b>curslist</b> must have been created within the
+context of the same transaction.
+<p>The Db::join method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The Db::join method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The <a href="../api_cxx/dbc_put.html">Dbc::put</a> or <a href="../api_cxx/dbc_del.html">Dbc::del</a> functions were called.
+</dl>
+<p>The Db::join method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db::join method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+</pre></h3>
+<h1>Description</h1>
+<p>The Db::key_range method returns an estimate of the proportion of keys
+that are less than, equal to and greater than the specified key.  The
+underlying database must be of type Btree.
+<p>The information is returned in the <b>key_range</b> argument, which
+contains three elements of type double, <b>less</b>, <b>equal</b> and
+<b>greater</b>.  Values are in the range of 0 to 1, e.g., if the field
+<b>less</b> is 0.05, that indicates that 5% of the keys in the database
+are less than the key argument.  The value for <b>equal</b> will be zero
+if there is no matching key and non-zero otherwise.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_cxx/txn_begin.html">DbEnv::txn_begin</a>, otherwise, NULL.
+The Db::key_range method does not retain the locks it acquires for the
+life of the transaction, so estimates may not be repeatable.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>The Db::key_range method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The Db::key_range method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>DB_LOCK_DEADLOCK<dd>The operation was selected to resolve a deadlock.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The underlying database was not of type Btree.
+</dl>
+<p>The Db::key_range method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db::key_range method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+Db::open(const char *file,

+</pre></h3>
+<h1>Description</h1>
+<p>The currently supported Berkeley DB file formats (or <i>access methods</i>)
+are Btree, Hash, Queue and Recno.  The Btree format is a representation
+of a sorted, balanced tree structure.  The Hash format is an extensible,
+dynamic hashing scheme.  The Queue format supports fast access to
+fixed-length records accessed by sequentially or logical record number.
+The Recno format supports fixed- or variable-length records, accessed
+sequentially or by logical record number, and optionally retrieved from
+a flat text file.
+<p>Storage and retrieval for the Berkeley DB access methods are based on key/data
+pairs, see <a href="../api_cxx/dbt_class.html">Dbt</a> for more information.
+<p>The Db::open interface opens the database represented by the
+<b>file</b> and <b>database</b> arguments for both reading and writing.
+The <b>file</b> argument is used as the name of a physical file on disk
+that will be used to back the database.  The <b>database</b> argument is
+optional and allows applications to have multiple logical databases in a
+single physical file.  While no <b>database</b> argument needs to be
+specified, it is an error to attempt to open a second database in a
+<b>file</b> that was not initially created using a <b>database</b> name.
+In-memory databases never intended to be preserved on disk may
+be created by setting both the <b>file</b> and <b>database</b> arguments
+to NULL.  Note that in-memory databases can only ever be shared by
+sharing the single database handle that created them, in circumstances
+where doing so is safe.
+<p>The <b>type</b> argument is of type DBTYPE
+and must be set to one of DB_BTREE, DB_HASH,
+DB_QUEUE, DB_RECNO or DB_UNKNOWN, except
+that databases of type DB_QUEUE are restricted to one per
+<b>file</b>.  If <b>type</b> is DB_UNKNOWN, the database must
+already exist and Db::open will automatically determine its type.
+The <a href="../api_cxx/db_get_type.html">Db::get_type</a> method may be used to determine the underlying type of
+databases opened using DB_UNKNOWN.
+<p>The <b>flags</b> and <b>mode</b> arguments specify how files will be opened
+and/or created if they do not already exist.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_CREATE">DB_CREATE</a><dd>Create any underlying files, as necessary.  If the files do not already
+exist and the DB_CREATE flag is not specified, the call will fail.
+<p><dt><a name="DB_EXCL">DB_EXCL</a><dd>Return an error if the file already exists.  Underlying filesystem
+primitives are used to implement this flag.  For this reason it is only
+applicable to the physical file and cannot be used to test if a database
+in a file already exists.
+<p>The DB_EXCL flag is only meaningful when specified with the
+DB_CREATE flag.
+<p><dt><a name="DB_NOMMAP">DB_NOMMAP</a><dd>Do not map this database into process memory (see the description of the
+<a href="../api_cxx/env_set_mp_mmapsize.html">DbEnv::set_mp_mmapsize</a> method for further information).
+<p><dt><a name="DB_RDONLY">DB_RDONLY</a><dd>Open the database for reading only.  Any attempt to modify items in the
+database will fail regardless of the actual permissions of any underlying
+files.
+<p><dt><a name="DB_THREAD">DB_THREAD</a><dd>Cause the <a href="../api_cxx/db_class.html">Db</a> handle returned by Db::open to be
+<i>free-threaded</i>, that is, useable by multiple threads within a
+single address space.
+<p><dt><a name="DB_TRUNCATE">DB_TRUNCATE</a><dd>Physically truncate the underlying file, discarding all previous databases
+it might have held.  Underlying filesystem primitives are used to
+implement this flag.  For this reason it is only applicable to the
+physical file and cannot be used to discard databases within a file.
+<p>The DB_TRUNCATE flag cannot be transaction protected, and it is
+an error to specify it in a transaction protected environment.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by the access methods
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>Calling Db::open is a reasonably expensive operation, and
+maintaining a set of open databases will normally be preferable to
+repeatedly open and closing the database for each new query.
+<p>The Db::open method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<p><dt>DB_HOME<dd>If the <b>dbenv</b> argument to <a href="../api_c/db_create.html">db_create</a> was initialized using
+<a href="../api_cxx/env_open.html">DbEnv::open</a> the environment variable <b>DB_HOME</b> may be used

+<h1>Description</h1>
+<p>The Db::put method stores key/data pairs in the database.  The default
+behavior of the Db::put function is to enter the new key/data
+pair, replacing any previously existing key if duplicates are disallowed,
+or adding a duplicate data item if duplicates are allowed.  If the database
+supports duplicates, the Db::put method adds the new data value at the
+end of the duplicate set.  If the database supports sorted duplicates,
+the new data value is inserted at the correct sorted location.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_cxx/txn_begin.html">DbEnv::txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_APPEND">DB_APPEND</a><dd>Append the key/data pair to the end of the database.  For the
+DB_APPEND flag to be specified, the underlying database must be
+a Queue or Recno database.  The record number allocated to the record is
+returned in the specified <b>key</b>.
+<p>There is a minor behavioral difference between the Recno and Queue access
+methods for the DB_APPEND flag.  If a transaction enclosing a
+Db::put operation with the DB_APPEND flag aborts, the
+record number may be decremented (and later re-allocated by a subsequent
+DB_APPEND operation) by the Recno access method, but will not be
+decremented or re-allocated by the Queue access method.
+<p><dt><a name="DB_NODUPDATA">DB_NODUPDATA</a><dd>In the case of the Btree and Hash access methods, enter the new key/data
+pair only if it does not already appear in the database.  If the
+key/data pair already appears in the database, <a href="../api_cxx/dbc_put.html#DB_KEYEXIST">DB_KEYEXIST</a> is
+returned.  The DB_NODUPDATA flag may only be specified if the
+underlying database has been configured to support sorted duplicates.
+<p>The DB_NODUPDATA flag may not be specified to the Queue or Recno
+access methods.
+<p><dt><a name="DB_NOOVERWRITE">DB_NOOVERWRITE</a><dd>Enter the new key/data pair only if the key does not already appear in

+a call to Db::put with the DB_NOOVERWRITE flag set will
+fail if the key already exists in the database.

+<p>Otherwise, the Db::put method either returns a non-zero error value or throws an exception that

+#include &lt;db_cxx.h&gt;
+<p>
+int
+Db::remove(const char *file, const char *database, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The Db::remove interface removes the database specified by the
+<b>file</b> and <b>database</b> arguments.  If no <b>database</b> is
+specified, the physical file represented by <b>file</b> is removed,
+incidentally removing all databases that it contained.
+<p>If a physical file is being removed and logging is currently enabled in
+the database environment, no database in the file may be open when the
+Db::remove method is called.  Otherwise, no reference count of database
+use is maintained by Berkeley DB.  Applications should not remove databases that
+are currently in use.  In particular, some architectures do not permit
+the removal of files with open handles.  On these architectures, attempts
+to remove databases that are currently in use will fail.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>Once Db::remove has been called, regardless of its return, the
+<a href="../api_cxx/db_class.html">Db</a> handle may not be accessed again.
+<p>The Db::remove method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Environment Variables</h1>
+<p><dl compact>
+<p><dt>DB_HOME<dd>If the <b>dbenv</b> argument to <a href="../api_c/db_create.html">db_create</a> was initialized using
+<a href="../api_cxx/env_open.html">DbEnv::open</a> the environment variable <b>DB_HOME</b> may be used
+as the path of the database environment home.  Specifically, Db::remove
+is affected by the configuration value DB_DATA_DIR.
+</dl>
+<h1>Errors</h1>
+<p>The Db::remove method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>A database in the file is currently open.
+</dl>
+<p>The Db::remove method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db::remove method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+If a callback method is specified using the
+Db::set_append_recno method, it will be called after the record number
+has been selected but before the data has been stored.
+The callback function must return 0 on success and <b>errno</b> or
+a value outside of the Berkeley DB error name space on failure.
+<p>The called function must take three arguments: a reference to the
+enclosing database handle, the data <a href="../api_cxx/dbt_class.html">Dbt</a> to be stored and the
+selected record number.  The called function may then modify the data
+<a href="../api_cxx/dbt_class.html">Dbt</a>.
+<p>The Db::set_append_recno interface may only be used to configure Berkeley DB before

+called when it is necessary to compare a key specified by the
+application with a key currently stored in the tree.  The first argument
+to the comparison function is the <a href="../api_cxx/dbt_class.html">Dbt</a> representing the
+application supplied key, the second is the current tree's key.
+<p>The comparison function must return an integer value less than, equal
+to, or greater than zero if the first key argument is considered to be
+respectively less than, equal to, or greater than the second key
+argument.  In addition, the comparison function must cause the keys in
+the database to be <i>well-ordered</i>.  The comparison function
+must correctly handle any key values used by the application (possibly
+including zero-length keys).  In addition, when Btree key prefix
+comparison is being performed (see <a href="../api_cxx/db_set_bt_prefix.html">Db::set_bt_prefix</a> for more
+information), the comparison routine may be passed a prefix of any
+database key.  The <b>data</b> and <b>size</b> fields of the
+<a href="../api_cxx/dbt_class.html">Dbt</a> are the only fields that may be used for the purposes of
+this comparison.
+<p>If no comparison function is specified, the keys are compared lexically,
+with shorter keys collating before longer keys.  The same comparison
+method must be used each time a particular Btree is opened.
+<p>The Db::set_bt_compare interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/db_open.html">Db::open</a> interface is called.
+<p>The Db::set_bt_compare method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<h1>Description</h1>
+<p>Set the Btree prefix function.  The prefix function must return the
+number of bytes of the second key argument that would be required by
+the Btree key comparison function to determine the second key argument's
+ordering relationship with respect to the first key argument.  If the
+two keys are equal, the key length should be returned.  The prefix
+function must correctly handle any key values used by the application
+(possibly including zero-length keys).  The <b>data</b> and
+<b>size</b> fields of the <a href="../api_cxx/dbt_class.html">Dbt</a> are the only fields that may be
+used for the purposes of this determination.
+<p>The prefix function is used to determine the amount by which keys stored
+on the Btree internal pages can be safely truncated without losing their
+uniqueness.  See the <a href="../ref/am_conf/bt_prefix.html">Btree
+prefix comparison</a> section of the Reference Guide for more details about
+how this works.  The usefulness of this is data dependent, but in some
+data sets can produce significantly reduced tree sizes and search times.
+<p>If no prefix function or key comparison function is specified by the
+application, a default lexical comparison function is used as the prefix
+function.  If no prefix function is specified and a key comparison
+function is specified, no prefix function is used.  It is an error to
+specify a prefix function without also specifying a key comparison
+function.
+<p>The Db::set_bt_prefix interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/db_open.html">Db::open</a> interface is called.
+<p>The Db::set_bt_prefix method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<h1>Description</h1>
+<p>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.  For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>As databases opened within Berkeley DB environments use the cache specified to
+the environment, it is an error to attempt to set a cache in a database
+created within an environment.
+<p>The Db::set_cachesize interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/db_open.html">Db::open</a> interface is called.
+<p>The Db::set_cachesize method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<h1>Description</h1>
+<p>Set the duplicate data item comparison function.  The comparison function
+is called when it is necessary to compare a data item specified by the
+application with a data item currently stored in the tree.  The first
+argument to the comparison function is the <a href="../api_cxx/dbt_class.html">Dbt</a> representing the
+application's data item, the second is the current tree's data item.
+<p>The comparison function must return an integer value less than, equal
+to, or greater than zero if the first data item argument is considered
+to be respectively less than, equal to, or greater than the second data
+item argument.  In addition, the comparison function must cause the data
+items in the set to be <i>well-ordered</i>.  The comparison function
+must correctly handle any data item values used by the application
+(possibly including zero-length data items).  The <b>data</b> and
+<b>size</b>  fields of the <a href="../api_cxx/dbt_class.html">Dbt</a> are the only fields that may be
+used for the purposes of this comparison.
+<p>If no comparison function is specified, the data items are compared
+lexically, with shorter data items collating before longer data items.
+The same duplicate data item comparison method must be used each time
+a particular Btree is opened.
+<p>The Db::set_dup_compare interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/db_open.html">Db::open</a> interface is called.
+<p>The Db::set_dup_compare method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+When an error occurs in the Berkeley DB library, an exception is thrown or an

+<p>The Db::set_errcall method is used to enhance the mechanism for reporting error
+messages to the application.  In some cases, when an error occurs, Berkeley DB
+will call <b>db_errcall_fcn</b> with additional error information.  The
+function must be defined with two arguments; the first will be the prefix
+string (as previously set by <a href="../api_cxx/db_set_errpfx.html">Db::set_errpfx</a> or
+<a href="../api_cxx/env_set_errpfx.html">DbEnv::set_errpfx</a>), the second will be the error message string.
+It is up to the <b>db_errcall_fcn</b> method to display the error
+message in an appropriate manner.
+<p>Alternatively, you can use the <a href="../api_cxx/env_set_error_stream.html">DbEnv::set_error_stream</a> method to display
+the additional information via an output stream, or the <a href="../api_cxx/db_set_errfile.html">Db::set_errfile</a>
+or <a href="../api_cxx/env_set_errfile.html">DbEnv::set_errfile</a> methods to display the additional information via a C
+library FILE *.  You should not mix these approaches.
+<p>This error logging enhancement does not slow performance or significantly
+increase application size, and may be run during normal operation as well
+as during application debugging.
+<p>For <a href="../api_cxx/db_class.html">Db</a> handles opened inside of Berkeley DB environments, calling the
+Db::set_errcall method affects the entire environment and is equivalent to calling
+the <a href="../api_cxx/env_set_errcall.html">DbEnv::set_errcall</a> method.

+<p>Some operations performed by the Berkeley DB library can take non-trivial
+amounts of time.  The Db::set_feedback method can be used by
+applications to monitor progress within these operations.
+<p>When an operation is likely to take a long time, Berkeley DB will call the
+specified callback method.  This method must be declared with
+three arguments: the first will be a reference to the enclosing database
+handle, the second a flag value, and the third the percent of the
+operation that has been completed, specified as an integer value between
+0 and 100.  It is up to the callback method to display this
+information in an appropriate manner.
+<p>The <b>opcode</b> argument may take on any of the following values:
+<p><dl compact>
+<p><dt><a name="DB_UPGRADE">DB_UPGRADE</a><dd>The underlying database is being upgraded.
+<p><dt><a name="DB_VERIFY">DB_VERIFY</a><dd>The underlying database is being verified.
+</dl>
+<p>The Db::set_feedback interface may be used to configure Berkeley DB at any time
+during the life of the application.
+<p>The Db::set_feedback method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<h3><pre>
+#include &lt;db_cxx.h&gt;
+<p>
+int
+Db::set_flags(u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>Calling Db::set_flags is additive, there is no way to clear flags.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<h3>Btree</h3>
+<p>The following flags may be specified for the Btree access method:
+<p><dl compact>
+<p><dt><a name="DB_DUP">DB_DUP</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+order of insertion, unless the ordering is otherwise specified by use of
+a cursor operation.  It is an error to specify both DB_DUP and
+DB_RECNUM.
+<p><dt><a name="DB_DUPSORT">DB_DUPSORT</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+duplicate comparison function.
+If the application does not specify a comparison function using the
+<a href="../api_cxx/db_set_dup_compare.html">Db::set_dup_compare</a> method, a default, lexical comparison will be
+used.
+It is an error to specify both DB_DUPSORT and DB_RECNUM.
+<p><dt><a name="DB_RECNUM">DB_RECNUM</a><dd>Support retrieval from the Btree using record numbers.  For more
+information, see the DB_GET_RECNO flag to the <a href="../api_cxx/db_get.html">Db::get</a> and
+<a href="../api_cxx/dbc_get.html">Dbc::get</a> methods.
+<p>Logical record numbers in Btree databases are mutable in the face of
+record insertion or deletion.  See the DB_RENUMBER flag in the Recno
+access method information for further discussion.
+<p>Maintaining record counts within a Btree introduces a serious point of
+contention, namely the page locations where the record counts are stored.
+In addition, the entire tree must be locked during both insertions and
+deletions, effectively single-threading the tree for those operations.
+Specifying DB_RECNUM can result in serious performance degradation for
+some applications and data sets.
+<p>It is an error to specify both DB_DUP and DB_RECNUM.
+<p><dt><a name="DB_REVSPLITOFF">DB_REVSPLITOFF</a><dd>Turn off reverse splitting in the Btree.  As pages are emptied in a
+database, the Berkeley DB Btree implementation attempts to coalesce empty pages
+into higher-level pages in order to keep the tree as small as possible
+and minimize tree search time.  This can hurt performance in applications
+with cyclical data demands, that is, applications where the database grows
+and shrinks repeatedly.  For example, because Berkeley DB does page-level
+locking, the maximum level of concurrency in a database of 2 pages is far
+smaller than that in a database of 100 pages, and so a database that has
+shrunk to a minimal size can cause severe deadlocking when a new cycle of
+data insertion begins.
+</dl>
+<h3>Hash</h3>
+<p>The following flags may be specified for the Hash access method:
+<p><dl compact>
+<p><dt><a name="DB_DUP">DB_DUP</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+order of insertion, unless the ordering is otherwise specified by use of
+a cursor operation.  It is an error to specify both DB_DUP and
+DB_RECNUM.
+<p><dt><a name="DB_DUPSORT">DB_DUPSORT</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+duplicate comparison function.
+If the application does not specify a comparison function using the
+<a href="../api_cxx/db_set_dup_compare.html">Db::set_dup_compare</a> method, a default, lexical comparison will be
+used.
+It is an error to specify both DB_DUPSORT and DB_RECNUM.
+</dl>
+<h3>Queue</h3>
+<p>There are no additional flags that may be specified for the Queue access
+method.
+<h3>Recno</h3>
+<p>The following flags may be specified for the Recno access method:
+<p><dl compact>
+<p><dt><a name="DB_RENUMBER">DB_RENUMBER</a><dd>Specifying the DB_RENUMBER flag causes the logical record numbers to be
+mutable, and change as records are added to and deleted from the database.
+For example, the deletion of record number 4 causes records numbered 5
+and greater to be renumbered downward by 1.  If a cursor was positioned
+to record number 4 before the deletion, it will reference the new record
+number 4, if any such record exists, after the deletion.  If a cursor was
+positioned after record number 4 before the deletion, it will be shifted
+downward 1 logical record, continuing to reference the same record as it
+did before.
+<p>Using the <a href="../api_cxx/db_put.html">Db::put</a> or <a href="../api_cxx/dbc_put.html">Dbc::put</a> interfaces to create new
+records will cause the creation of multiple records if the record number
+is more than one greater than the largest record currently in the
+database.  For example, creating record 28, when record 25 was previously
+the last record in the database, will create records 26 and 27 as well as
+28.  Attempts to retrieve records that were created in this manner will
+result in an error return of <a href="../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a>.
+<p>If a created record is not at the end of the database, all records
+following the new record will be automatically renumbered upward by 1.
+For example, the creation of a new record numbered 8 causes records
+numbered 8 and greater to be renumbered upward by 1.  If a cursor was
+positioned to record number 8 or greater before the insertion, it will be
+shifted upward 1 logical record, continuing to reference the same record
+as it did before.
+<p>For these reasons, concurrent access to a Recno database with the
+DB_RENUMBER flag specified may be largely meaningless, although
+it is supported.
+<p><dt><a name="DB_SNAPSHOT">DB_SNAPSHOT</a><dd>This flag specifies that any specified <b>re_source</b> file be read in
+its entirety when <a href="../api_cxx/db_open.html">Db::open</a> is called.  If this flag is not
+specified, the <b>re_source</b> file may be read lazily.
+</dl>
+<p>The Db::set_flags interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/db_open.html">Db::open</a> interface is called.
+<p>The Db::set_flags method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<p>On systems where there may be multiple library versions of malloc (notably

+the application will use to free it.  To avoid this problem, the
+Db::set_malloc method can be used to pass Berkeley DB a reference to the
+application's allocation routine, in which case it will be used to
+allocate the memory returned when the <a href="../api_cxx/dbt_class.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a> flag is set.
+<p>The method specified must match the calling conventions of the

+<p>The Db::set_malloc interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/db_open.html">Db::open</a> interface is called.

+</pre></h3>
+<h1>Description</h1>
+<p>Errors can occur in the Berkeley DB library where the only solution is to shut
+down the application and run recovery.  (For example, if Berkeley DB is unable
+to write log records to disk because there is insufficient disk space.)
+In these cases, when the C++ error model has been configured so that the
+individual Berkeley DB methods return error codes (see <a href="../api_cxx/except_class.html">DbException</a> for
+more information), the value <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is returned by Berkeley DB
+methods.
+<p>In these cases, it is also often simpler to shut down the application when
+such errors occur rather than attempting to gracefully return up the stack.
+The Db::set_paniccall method is used to specify a method to be called when
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is about to be returned from a Berkeley DB method.  When
+called, the <b>dbenv</b> argument will be a reference to the current
+environment, and the <b>errval</b> argument is the error value that would
+have been returned to the calling method.
+<p>For <a href="../api_cxx/db_class.html">Db</a> handles opened inside of Berkeley DB environments, calling the
+Db::set_paniccall method affects the entire environment and is equivalent to calling
+the <a href="../api_cxx/env_set_paniccall.html">DbEnv::set_paniccall</a> method.
+<p>The Db::set_paniccall interface may be used to configure Berkeley DB at any time
+during the life of the application.
+<p>The Db::set_paniccall method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<h3><pre>
+#include &lt;db_cxx.h&gt;
+<p>
+int
+Db::set_re_source(char *re_source);
+</pre></h3>
+<h1>Description</h1>
+<p>Set the underlying source file for the Recno access method.  The purpose
+of the <b>re_source</b> value is to provide fast access and modification
+to databases that are normally stored as flat text files.
+<p>If the <b>re_source</b> field is set, it specifies an underlying flat
+text database file that is read to initialize a transient record number
+index.  In the case of variable length records, the records are separated
+as specified by <a href="../api_cxx/db_set_re_delim.html">Db::set_re_delim</a>.  For example, standard UNIX
+byte stream files can be interpreted as a sequence of variable length
+records separated by &lt;newline&gt; characters.
+<p>In addition, when cached data would normally be written back to the
+underlying database file (e.g., the <a href="../api_cxx/db_close.html">Db::close</a> or <a href="../api_cxx/db_sync.html">Db::sync</a>
+methods are called), the in-memory copy of the database will be written
+back to the <b>re_source</b> file.
+<p>By default, the backing source file is read lazily, i.e., records are not
+read from the file until they are requested by the application.
+<b>If multiple processes (not threads) are accessing a Recno database
+concurrently and either inserting or deleting records, the backing source
+file must be read in its entirety before more than a single process
+accesses the database, and only that process should specify the backing
+source file as part of the <a href="../api_cxx/db_open.html">Db::open</a> call.  See the <a href="../api_cxx/db_set_flags.html#DB_SNAPSHOT">DB_SNAPSHOT</a>
+flag for more information.</b>
+<p><b>Reading and writing the backing source file specified by <b>re_source</b>
+cannot be transactionally protected because it involves filesystem
+operations that are not part of the Db transaction methodology.</b>
+For this reason, if a temporary database is used to hold the records,
+i.e., a NULL was specified as the <b>file</b> argument to <a href="../api_cxx/db_open.html">Db::open</a>,
+it is possible to lose the contents of the <b>re_source</b> file, e.g.,
+if the system crashes at the right instant.
+If a file is used to hold the database, i.e., a file name was specified
+as the <b>file</b> argument to <a href="../api_cxx/db_open.html">Db::open</a>, normal database
+recovery on that file can be used to prevent information loss,
+although it is still possible that the contents of <b>re_source</b>
+will be lost if the system crashes.
+<p>The <b>re_source</b> file must already exist (but may be zero-length) when
+<a href="../api_cxx/db_open.html">Db::open</a> is called.
+<p>It is not an error to specify a read-only <b>re_source</b> file when
+creating a database, nor is it an error to modify the resulting database.
+However, any attempt to write the changes to the backing source file using
+either the <a href="../api_cxx/db_sync.html">Db::sync</a> or <a href="../api_cxx/db_close.html">Db::close</a> methods will fail, of course.
+Specify the <a href="../api_cxx/db_close.html#DB_NOSYNC">DB_NOSYNC</a> flag to the <a href="../api_cxx/db_close.html">Db::close</a> method to stop it
+from attempting to write the changes to the backing file, instead, they
+will be silently discarded.
+<p>For all of the above reasons, the <b>re_source</b> field is generally
+used to specify databases that are read-only for <a href="../api_cxx/db_class.html">Db</a> applications,
+and that are either generated on the fly by software tools, or modified
+using a different mechanism, e.g., a text editor.
+<p>The Db::set_re_source interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/db_open.html">Db::open</a> interface is called.
+<p>The Db::set_re_source method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+extern "C" {

+};
+int
+Db::stat(void *sp, db_malloc_fcn_type db_malloc, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The Db::stat method creates a statistical structure and
+copies a pointer to it into user-specified memory locations.
+Specifically, if <b>sp</b> is non-NULL, a pointer to the statistics
+for the database are copied into the memory location it references.
+<p>Statistical structures are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_CACHED_COUNTS">DB_CACHED_COUNTS</a><dd>Return a cached count of the keys and records in a database.  This flag
+makes it possible for applications to request an possibly approximate key
+and record count without incurring the performance penalty of traversing
+the entire database.  The statistics information described for the access
+method <b>XX_nkeys</b> and <b>XX_ndata</b> fields below is filled in,
+but no other information is collected.  If the cached information has
+never been set, the fields will be returned set to 0.
+<p><dt><a name="DB_RECORDCOUNT">DB_RECORDCOUNT</a><dd>Return a count of the records in a Btree or Recno Access Method database.
+This flag makes it possible for applications to request a record count
+without incurring the performance penalty of traversing the entire
+database.  The statistics information described for the <b>bt_nkeys</b>
+field below is filled in, but no other information is collected.
+<p>This option is only available for Recno databases, or Btree databases
+where the underlying database was created with the <a href="../api_cxx/db_set_flags.html#DB_RECNUM">DB_RECNUM</a>
+flag.
+</dl>
+<p>The Db::stat method may access all of the pages in the database,
+incurring a severe performance penalty as well as possibly flushing the
+underlying buffer pool.
+<p>In the presence of multiple threads or processes accessing an active
+database, the information returned by Db::stat may be out-of-date.
+<p>If the database was not opened readonly and the DB_CACHED_COUNTS
+flag was not specified, the cached key and record numbers will be updated
+after the statistical information has been gathered.
+<p>The Db::stat method cannot be transaction protected.  For this reason,
+it should be called in a thread of control that has no open cursors or
+active transactions.
+<p>The Db::stat method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h3>Hash Statistics</h3>
+<p>In the case of a Hash database,
+the statistics are stored in a structure of type DB_HASH_STAT.  The
+following fields will be filled in:
+<p><dl compact>

+<h1>Description</h1>
+<p>The Db::sync method flushes any cached information to disk.
+<p>If the database is in memory only, the Db::sync method has no effect and
+will always succeed.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>See <a href="../api_cxx/db_close.html">Db::close</a> for a discussion of Berkeley DB and cached data.
+<p>The Db::sync method either returns a non-zero error value or throws an exception that

+dirty pages in the cache.  (The only reason to return
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> is if another thread of control was writing pages

+Db::sync method was being called.  For this reason, a return of
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> can normally be ignored, or, in cases where it is

+</pre></h3>
+<h1>Description</h1>
+<p>The Db::upgrade method upgrades all of the databases included in the
+file <b>file</b>, if necessary.  If no upgrade is necessary,
+Db::upgrade always returns success.
+<p><b>Database upgrades are done in place and are destructive, e.g., if pages
+need to be allocated and no disk space is available, the database may be
+left corrupted.  Backups should be made before databases are upgraded.
+See <a href="../ref/am/upgrade.html">Upgrading databases</a> for more
+information.</b>
+<p>Unlike all other database operations, Db::upgrade may only be done
+on a system with the same byte-order as the database.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_DUPSORT">DB_DUPSORT</a><dd><b>This flag is only meaningful when upgrading databases from
+releases before the Berkeley DB 3.1 release.</b>
+<p>As part of the upgrade from the Berkeley DB 3.0 release to the 3.1 release, the
+on-disk format of duplicate data items changed.  To correctly upgrade the
+format requires applications specify if duplicate data items in the
+database are sorted or not.  Specifying the DB_DUPSORT flag
+informs Db::upgrade that the duplicates are sorted, otherwise they
+are assumed to be unsorted.  Incorrectly specifying the value of this flag
+may lead to database corruption.
+<p>Further, because the Db::upgrade method upgrades a physical file
+(including all of the databases it contains), it is not possible to use
+Db::upgrade to upgrade files where some of the databases it
+includes have sorted duplicate data items and some of the databases it
+includes have unsorted duplicate data items.  If the file does not have
+more than a single database, or the databases do not support duplicate
+data items, or all of the databases that support duplicate data items
+support the same style of duplicates (either sorted or unsorted),
+Db::upgrade will work correctly as long as the DB_DUPSORT
+flag is correctly specified.  Otherwise, the file cannot be upgraded using
+Db::upgrade, and must be upgraded manually by dumping and
+re-loading the databases.
+</dl>
+<p>The Db::upgrade method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Environment Variables</h1>
+<p><dl compact>
+<p><dt>DB_HOME<dd>If the <b>dbenv</b> argument to <a href="../api_c/db_create.html">db_create</a> was initialized using
+<a href="../api_cxx/env_open.html">DbEnv::open</a> the environment variable <b>DB_HOME</b> may be used
+as the path of the database environment home.  Specifically, Db::upgrade
+is affected by the configuration value DB_DATA_DIR.
+</dl>
+<h1>Errors</h1>
+<p>The Db::upgrade method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The database is not in the same byte-order as the system.
+</dl>
+<p><dl compact>
+<p><dt><a name="DB_OLD_VERSION">DB_OLD_VERSION</a><dd>The database cannot be upgraded by this version of the Berkeley DB software.
+</dl>
+<p>The Db::upgrade method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db::upgrade method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+int
+Db::verify(const char *file,
+    const char *database, ostream *outfile, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The Db::verify method verifies the integrity of all databases in the
+file specified by the file argument, and optionally outputs the databases'
+key/data pairs to a file stream.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="DB_SALVAGE">DB_SALVAGE</a><dd>Write the key/data pairs from all databases in the file to the file stream
+named in
+the <b>outfile</b> argument.  The output format is the same as that
+specified for the <a href="../utility/db_dump.html">db_dump</a> utility and can be used as input for
+the <a href="../utility/db_load.html">db_load</a> utility.
+<p>Because the key/data pairs are output in page order as opposed to the sort
+order used by <a href="../utility/db_dump.html">db_dump</a>, using Db::verify to dump key/data
+pairs normally produces less than optimal loads for Btree databases.
+</dl>
+<p>In addition, the following flags may be set by bitwise inclusively <b>OR</b>'ing them into the
+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="DB_AGGRESSIVE">DB_AGGRESSIVE</a><dd>Output <b>all</b> the key/data pairs in the file that can be found.
+By default, Db::verify does not assume corruption.  For example,
+if a key/data pair on a page is marked as deleted, it is not then written
+to the output file.  When DB_AGGRESSIVE is specified, corruption
+is assumed, and any key/data pair that can be found is written.  In this
+case, key/data pairs that are corrupted or have been deleted may appear
+in the output (even if the file being salvaged is in no way corrupt), and
+the output will almost certainly require editing before being loaded into
+a database.
+<p><dt><a name="DB_NOORDERCHK">DB_NOORDERCHK</a><dd>Skip the database checks for btree and duplicate sort order and for
+hashing.
+<p>The Db::verify method normally verifies that btree keys and duplicate
+items are correctly sorted and hash keys are correctly hashed.  If the
+file being verified contains multiple databases using differing sorting
+or hashing algorithms, some of them must necessarily fail database
+verification as only one sort order or hash function can be specified
+before Db::verify is called.  To verify files with multiple
+databases having differing sorting orders or hashing functions, first
+perform verification of the file as a whole by using the
+DB_NOORDERCHK flag, and then individually verify the sort order
+and hashing function for each database in the file using the
+DB_ORDERCHKONLY flag.
+<p><dt><a name="DB_ORDERCHKONLY">DB_ORDERCHKONLY</a><dd>Perform the database checks for btree and duplicate sort order and for
+hashing, skipped by DB_NOORDERCHK.
+<p>When this flag is specified, a <b>database</b> argument should also be
+specified, indicating the database in the physical file which is to be
+checked.  This flag is only safe to use on databases that have already
+successfully been verified using Db::verify with the
+DB_NOORDERCHK flag set.
+</dl>
+<p>The database argument must be set to NULL except when the
+DB_ORDERCHKONLY flag is set.
+<p>The Db::verify method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, 0 on success, and <a href="../ref/program/errorret.html#DB_VERIFY_BAD">DB_VERIFY_BAD</a> if a database is corrupted.  When the
+DB_SALVAGE flag is specified, the <a href="../ref/program/errorret.html#DB_VERIFY_BAD">DB_VERIFY_BAD</a> return
+means that all key/data pairs in the file may not have been successfully
+output.

+<h1>Description</h1>
+<p>This manual page describes the specific details of the Dbt class,
+used to encode keys and data items in a database.
+        <a name="3"><!--meow--></a>    
+<h3>Key/Data Pairs</h3>
+<p>Storage and retrieval for the Db access methods are based on
+key/data pairs.  Both key and data items are represented by Dbt
+objects.  Key and data byte strings may reference strings of zero length
+up to strings of essentially unlimited length.  See
+<a href="../ref/program/dbsizes.html">Database limits</a> for more
+information.
+<p>The Dbt class provides simple access to an underlying data structure,
+whose elements can be examined or changed using the <b>set_</b> or
+<b>get_</b> methods.  The remainder of the manual page sometimes refers
+to these accesses using the underlying name, e.g., simply <b>ulen</b>
+instead of Dbt::get_ulen and Dbt::set_ulen.
+Dbt can be subclassed, providing a way to associate
+with it additional data, or references to other structures.
+<p>The constructors set all elements of the underlying structure to zero.
+The constructor with two arguments has the effect of setting all elements
+to zero except for the specified <b>data</b> and <b>size</b> elements.
+<p>In the case where the <b>flags</b> structure element is 0, when the
+application is providing Berkeley DB a key or data item to store into the
+database, Berkeley DB expects the <b>data</b> object to point to a byte string
+of <b>size</b> bytes.  When returning a key/data item to the application,
+Berkeley DB will store into the <b>data</b> object a pointer to a byte string
+of <b>size</b> bytes, and the memory referenced by the pointer will be
+allocated and managed by Berkeley DB.
+<p>The elements of the structure underlying the Dbt class are defined as follows:
+<p><dl compact>
+<p><dt>void *<a name="data">data</a>;<dd>A pointer to a byte string.
+This element is accessed using Dbt::get_data and
+Dbt::set_data, and may be initialized using one
+of the constructors.
+<p><dt>int offset;<dd>The number of bytes offset into the <b>data</b> array to determine the
+portion of the array actually used.
+This element is accessed using Dbt::get_offset and
+Dbt::set_offset.
+<p><dt>u_int32_t size;<dd>The length of <b>data</b>, in bytes.
+This element is accessed using Dbt::get_size and
+Dbt::set_size, and may be initialized
+using the constructor with two arguments.
+<p><dt>u_int32_t ulen;<dd>The size of the user's buffer (referenced by <b>data</b>), in bytes.
+This location is not written by the Db methods.
+<p>Note that applications can determine the length of a record by setting
+the <b>ulen</b> to 0 and checking the return value found in <b>size</b>.
+See the DB_DBT_USERMEM flag for more information.
+<p>This element is accessed using
+Dbt::get_ulen and Dbt::set_ulen.
+<p><dt>u_int32_t dlen;<dd>The length of the partial record being read or written by the application,
+in bytes.
+See the DB_DBT_PARTIAL flag for more information.
+This element is accessed using
+Dbt::get_dlen, and Dbt::set_dlen.
+<p><dt>u_int32_t doff;<dd>The offset of the partial record being read or written by the application,
+in bytes.
+See the DB_DBT_PARTIAL flag for more information.
+This element is accessed using
+Dbt::get_doff and Dbt::set_doff.
+<p><dt>u_int32_t flags;<dd>This element is accessed using Dbt::get_flags and
+Dbt::set_flags.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_DBT_MALLOC">DB_DBT_MALLOC</a><dd>When this flag is set Berkeley DB will allocate memory for the returned key
+or data item
+(using <b>malloc</b>(3) or the user-specified malloc method) and
+return a pointer to it in the <b>data</b> field of the key or data
+Dbt object.  As any allocated memory becomes the responsibility
+of the calling application, the caller must be able to determine if
+memory was allocated.
+<p>It is an error to specify more than one of DB_DBT_MALLOC,
+DB_DBT_REALLOC and DB_DBT_USERMEM.
+<p><dt><a name="DB_DBT_REALLOC">DB_DBT_REALLOC</a><dd>When this flag is set Berkeley DB
+will allocate memory for the returned key or data item (using
+<b>realloc</b>(3) or the user-specified realloc method) and return
+a pointer to it in the <b>data</b> field of the key or data Dbt
+object.  As any allocated memory becomes the responsibility of the
+calling application, the caller must be able to determine if memory was
+allocated.
+<p>It is an error to specify more than one of DB_DBT_MALLOC,
+DB_DBT_REALLOC and DB_DBT_USERMEM.
+<p><dt><a name="DB_DBT_USERMEM">DB_DBT_USERMEM</a><dd>The <b>data</b> field of the key or data object must reference memory
+that is at least <b>ulen</b> bytes in length.  If the length of the
+requested item is less than or equal to that number of bytes, the item
+is copied into the memory referenced by the <b>data</b> field.
+Otherwise, the <b>size</b> field is set to the length needed for the
+requested item, and the error ENOMEM is returned.
+<p>It is an error to specify more than one of DB_DBT_MALLOC,
+DB_DBT_REALLOC and DB_DBT_USERMEM.
+</dl>
+<p>If DB_DBT_MALLOC or DB_DBT_REALLOC is specified, Berkeley DB
+allocates a properly sized byte array to contain the data.  This can be
+convenient if you know little about the nature of the data, specifically
+the size of data in the database.  However, if your application makes
+repeated calls to retrieve keys or data, you may notice increased garbage
+collection due to this allocation.  If you know the maximum size of data
+you are retrieving, you might decrease the memory burden and speed your
+application by allocating your own byte array and using
+DB_DBT_USERMEM.  Even if you don't know the maximum size, you can
+use this option and reallocate your array whenever your retrieval API call
+returns an ENOMEM error, or throws an exception encapsulating an ENOMEM.
+<p><dl compact>
+<p><dt><a name="DB_DBT_PARTIAL">DB_DBT_PARTIAL</a><dd>Do partial retrieval or storage of an item.  If the calling application
+is doing a get, the <b>dlen</b> bytes starting <b>doff</b> bytes from
+the beginning of the retrieved data record are returned as if they
+comprised the entire record.  If any or all of the specified bytes do
+not exist in the record, the get is successful and the existing bytes
+or nul bytes are returned.
+<p>For example, if the data portion of a retrieved record was 100 bytes,
+and a partial retrieval was done using a Dbt having a <b>dlen</b>
+field of 20 and a <b>doff</b> field of 85, the get call would succeed,
+the <b>data</b> field would reference the last 15 bytes of the record,
+and the <b>size</b> field would be set to 15.
+<p>If the calling application is doing a put, the <b>dlen</b> bytes starting
+<b>doff</b> bytes from the beginning of the specified key's data record
+are replaced by the data specified by the <b>data</b> and <b>size</b>
+objects.
+If <b>dlen</b> is smaller than <b>size</b>, the record will grow, and if
+<b>dlen</b> is larger than <b>size</b>, the record will shrink.
+If the specified bytes do not exist, the record will be extended using nul
+bytes as necessary, and the put call will succeed.
+<p>It is an error to attempt a partial put using the <a href="../api_cxx/db_put.html">Db::put</a>
+method in a database that supports duplicate records.
+Partial puts in databases supporting duplicate records must be done
+using a <a href="../api_cxx/dbc_class.html">Dbc</a> method.
+<p>It is an error to attempt a partial put with differing <b>dlen</b> and
+<b>size</b> values in Queue or Recno databases with fixed-length records.
+<p>For example, if the data portion of a retrieved record was 100 bytes,
+and a partial put was done using a Dbt having a <b>dlen</b>
+field of 20, a <b>doff</b> field of 85, and a <b>size</b> field of 30,
+the resulting record would be 115 bytes in length, where the last 30
+bytes would be those specified by the put call.

+<h3>Retrieved key/data permanence</h3>
+<p>When using the non-cursor Berkeley DB calls to retrieve key/data items (e.g.,
+<a href="../api_cxx/db_get.html">Db::get</a>), the memory referenced by the pointer stored into the
+Dbt is only valid until the next call to Berkeley DB using the
+Db handle returned by <a href="../api_cxx/db_open.html">Db::open</a>.  (This includes
+<b>any</b> use of the returned Db handle, including by another
+thread of control within the process.  For this reason, when multiple
+threads are using the returned DB handle concurrently, one of the
+DB_DBT_MALLOC, DB_DBT_REALLOC or DB_DBT_USERMEM
+flags must be specified for any non-cursor Dbt used for key or
+data retrieval.)
+<p>When using the cursor Berkeley DB calls to retrieve key/data items (e.g.,
+<a href="../api_cxx/dbc_get.html">Dbc::get</a>), the memory referenced by the pointer into the
+Dbt is only valid until the next call to Berkeley DB using the
+<a href="../api_cxx/dbc_class.html">Dbc</a> handle returned by <a href="../api_cxx/db_cursor.html">Db::cursor</a>.
+        <a name="6"><!--meow--></a>    
+<h3>Data alignment</h3>
+<p>The Berkeley DB access methods provide no guarantees about key/data byte string
+alignment, and applications are responsible for arranging any necessary
+alignment. The DB_DBT_MALLOC, DB_DBT_REALLOC and
+DB_DBT_USERMEM flags may be used to store returned items in memory
+of arbitrary alignment.
+        <a name="7"><!--meow--></a>    
+<h3>Logical Record Numbers</h3>
+<p>In all cases for the Queue and Recno access methods, and when calling the
+<a href="../api_cxx/db_get.html">Db::get</a> and <a href="../api_cxx/dbc_get.html">Dbc::get</a> functions with the
+<a href="../api_cxx/db_get.html#DB_SET_RECNO">DB_SET_RECNO</a> flag specified, the <b>data</b>
+field of the key must be a pointer to a memory location of type
+<b>db_recno_t</b>, as typedef'd in the #include &lt;db_cxx.h&gt; include file.
+This type is a 32-bit unsigned type,
+(which limits the number of logical records in a Queue or Recno database,
+and the maximum logical record which may be directly retrieved from a
+Btree database, to 4,294,967,296).  The <b>size</b> field of the key
+should be the size of that type, i.e.,
+in the C programming language, <b>sizeof(db_recno_t)</b>.
+<p>Logical record numbers are 1-based, not 0-based, i.e., the first record
+in the database is record number 1.

+<h1>Description</h1>
+<p>The DbEnv::close method closes the Berkeley DB environment, freeing any
+allocated resources and closing any underlying subsystems.
+<p>Calling DbEnv::close does not imply closing any databases that were
+opened in the environment.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
+<p>Where the environment was initialized with the <a href="../api_cxx/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a> flag,
+calling DbEnv::close does not release any locks still held by the
+closing process, providing functionality for long-lived locks.
+Processes that wish to have all their locks
+released can do so by issuing the appropriate <a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> call.
+<p>Where the environment was initialized with the <a href="../api_cxx/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a>
+flag, calling DbEnv::close implies calls to <a href="../api_cxx/memp_fclose.html">DbMpoolFile::close</a> for
+any remaining open files in the memory pool that were returned to this
+process by calls to <a href="../api_cxx/memp_fopen.html">DbMpoolFile::open</a>.  It does not imply a call to
+<a href="../api_cxx/memp_fsync.html">DbMpoolFile::sync</a> for those files.
+<p>Where the environment was initialized with the <a href="../api_cxx/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a> flag,
+calling DbEnv::close aborts any uncommitted transactions.
+(Applications are should not depend on this behavior. If the process' has
+already closed a database handle which is necessary to abort an
+uncommitted transaction, the Berkeley DB environment must then require that
+recovery be run before further operations are done, since once a
+transaction exists that cannot be committed or aborted, no future
+checkpoint can ever succeed.)
+<p>In multi-threaded applications, only a single thread may call
+DbEnv::close.
+<p>Once DbEnv::close has been called, regardless of its return,
+the Berkeley DB environment handle may not be accessed again.
+<p>The DbEnv::close method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The DbEnv::close method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv::close method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<p>
+int
+DbEnv::open(const char *db_home, u_int32_t flags, int mode);
+</pre></h3>
+<h1>Description</h1>
+<p>The DbEnv::open method is the interface for opening the Berkeley DB
+environment.  It provides a structure for creating a consistent
+environment for processes using one or more of the features of Berkeley DB.
+<p>The <b>db_home</b> argument to DbEnv::open (and file name
+resolution in general) is described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p>The <b>flags</b> argument specifies the subsystems that are initialized
+and how the application's environment affects Berkeley DB file naming, among
+other things.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p>As there are a large number of flags that can be specified, they have been
+grouped together by functionality.  The first group of flags indicate
+which of the Berkeley DB subsystems should be initialized:
+<p><dl compact>
+<p><dt><a name="DB_JOINENV">DB_JOINENV</a><dd>Join an existing environment.  This option allows applications to
+join an existing environment without knowing which Berkeley DB subsystems
+the environment supports.
+<p><dt><a name="DB_INIT_CDB">DB_INIT_CDB</a><dd>Initialize locking for the <a href="../ref/cam/intro.html">Berkeley DB Concurrent Data Store</a>
+product.  In this mode, Berkeley DB provides multiple reader/single writer
+access.  The only other subsystem that should be specified with the
+DB_INIT_CDB flag is DB_INIT_MPOOL.
+<p>Access method calls are largely unchanged when using this flag, although
+any cursors through which update operations (e.g., <a href="../api_cxx/dbc_put.html">Dbc::put</a>,
+<a href="../api_cxx/dbc_del.html">Dbc::del</a>) will be made must have the <a href="../api_cxx/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a> value
+set in the flags parameter to the cursor call that creates the cursor.
+See <a href="../api_cxx/db_cursor.html">Db::cursor</a> for more information.
+<p><dt><a name="DB_INIT_LOCK">DB_INIT_LOCK</a><dd>Initialize the locking subsystem.  This subsystem should be used when
+multiple processes or threads are going to be reading and writing a Berkeley DB
+database, so that they do not interfere with each other.  If all threads
+are accessing the database(s) read-only, then locking is unnecessary.
+When the DB_INIT_LOCK flag is specified, it is usually necessary to run
+the deadlock detector, as well.  See <a href="../utility/db_deadlock.html">db_deadlock</a> and
+<a href="../api_cxx/lock_detect.html">DbEnv::lock_detect</a> for more information.
+<p><dt><a name="DB_INIT_LOG">DB_INIT_LOG</a><dd>Initialize the logging subsystem.  This subsystem is used when recovery
+from application or system failure is necessary.
+<p>The log is stored in one or more files in the environment directory.
+Each file is named using the format <i>log.NNNNNNNNNN</i>, where
+<i>NNNNNNNNNN</i> is the sequence number of the file within the log.
+For further information, see
+<a href="../ref/log/limits.html">Log File Limits</a>.
+<p>If the log region is being created and log files are already present, the
+log files are reviewed and subsequent log writes are appended
+to the end of the log, rather than overwriting current log entries.
+<p><dt><a name="DB_INIT_MPOOL">DB_INIT_MPOOL</a><dd>Initialize the shared memory buffer pool subsystem.  This subsystem is
+used whenever the application is using any Berkeley DB access method.
+<p><dt><a name="DB_INIT_TXN">DB_INIT_TXN</a><dd>Initialize the transaction subsystem.  This subsystem is used when
+recovery and atomicity of multiple operations and recovery are important.
+The DB_INIT_TXN flag implies the DB_INIT_LOG flag.
+</dl>
+<p>The second group of flags govern what recovery, if any, is performed when
+the environment is initialized:
+<p><dl compact>
+<p><dt><a name="DB_RECOVER">DB_RECOVER</a><dd>Run normal recovery on this environment before opening it for normal use.
+If this flag is set, the DB_CREATE flag must also be set since the regions
+will be removed and recreated.
+<p><dt><a name="DB_RECOVER_FATAL">DB_RECOVER_FATAL</a><dd>Run catastrophic recovery on this environment before opening it for normal
+use.  If this flag is set, the DB_CREATE flag must also be set since the
+regions will be removed and recreated.
+</dl>
+<p>A standard part of the recovery process is to remove the existing Berkeley DB
+environment and create a new one in which to perform recovery.  If the
+thread of control performing recovery does not specify the correct region
+initialization information (e.g., the correct memory pool cache size),
+the result can be an application running in an environment with incorrect
+cache and other subsystem sizes.  For this reason, the thread of control
+performing recovery should either specify correct configuration
+information before calling the DbEnv::open method, or it should remove
+the environment after recovery is completed, leaving creation of the
+correctly sized environment to a subsequent call to DbEnv::open.
+<p>All Berkeley DB recovery processing must be single-threaded, that is, only a
+single thread of control may perform recovery or access a Berkeley DB
+environment while recovery is being performed.  As it is not an error to
+specify DB_RECOVER for an environment for which no recovery is
+required, it is reasonable programming practice for the thread of control
+responsible for performing recovery and creating the environment to always
+specify the DB_RECOVER flag during startup.
+<p>The DbEnv::open function returns successfully if DB_RECOVER
+or DB_RECOVER_FATAL is specified and no log files exist, so it is
+necessary to ensure all necessary log files are present before running
+recovery.  For further information, consult <a href="../utility/db_archive.html">db_archive</a> and
+<a href="../utility/db_recover.html">db_recover</a>.
+<p>The third group of flags govern file naming extensions in the environment:
+<p><dl compact>
+<!--$Id: m4.env_flags,v 10.9 2000/06/29 22:54:10 bostic Exp $-->
+<p><dt><a name="DB_USE_ENVIRON">DB_USE_ENVIRON</a><dd>The Berkeley DB process' environment may be permitted to specify information to
+be used when naming files; see <a href="../ref/env/naming.html">Berkeley DB
+File Naming</a>.  As permitting users to specify which files are used can
+create security problems, environment information will be used in file
+naming for all users only if the DB_USE_ENVIRON flag is set.
+<p><dt><a name="DB_USE_ENVIRON_ROOT">DB_USE_ENVIRON_ROOT</a><dd>The Berkeley DB process' environment may be permitted to specify information to
+be used when naming files; see <a href="../ref/env/naming.html">Berkeley DB
+File Naming</a>.  As permitting users to specify which files are used can
+create security problems, if the DB_USE_ENVIRON_ROOT flag is set,
+environment information will be used for file naming only for users with
+appropriate permissions (e.g., on UNIX systems, users with a user-ID of 0).
+</dl>
+<p>Finally, there are a few additional, unrelated flags:
+<p><dl compact>
+<p><dt><a name="DB_CREATE">DB_CREATE</a><dd>Cause Berkeley DB subsystems to create any underlying files, as necessary.
+<p><dt><a name="DB_LOCKDOWN">DB_LOCKDOWN</a><dd>Lock shared Berkeley DB environment files and memory mapped databases into memory.
+<p><dt><a name="DB_PRIVATE">DB_PRIVATE</a><dd>Specify that the environment will only be accessed by a single process
+(although that process may be multi-threaded).  This flag has two effects
+on the Berkeley DB environment.  First, all underlying data structures are
+allocated from per-process memory instead of from shared memory that is
+potentially accessible to more than a single process.  Second, mutexes
+are only configured to work between threads.
+<p>This flag should not be specified if more than a single process is
+accessing the environment, as it is likely to cause database corruption
+and unpredictable behavior, e.g., if both a server application and the
+Berkeley DB utility <a href="../utility/db_stat.html">db_stat</a> will access the environment, the
+DB_PRIVATE flag should not be specified.
+<p><dt><a name="DB_SYSTEM_MEM">DB_SYSTEM_MEM</a><dd>Allocate memory from system shared memory instead of from memory backed
+by the filesystem.  See <a href="../ref/env/region.html">Shared Memory
+Regions</a> for more information.
+<p><dt><a name="DB_THREAD">DB_THREAD</a><dd>Cause the <a href="../api_cxx/dbenv_class.html">DbEnv</a> handle returned by DbEnv::open to be
+<i>free-threaded</i>, that is, useable by multiple threads within a
+single address space.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by Berkeley DB
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>The DbEnv::open method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Environment Variables</h1>
+<p><dl compact>
+<p><dt>DB_HOME<dd>The environment variable <b>DB_HOME</b> may be used as the path of
+the database home as described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+</dl>
+<h1>Errors</h1>
+<p>The DbEnv::open method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EAGAIN<dd>The shared memory region was locked and (repeatedly) unavailable.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>
+The DB_THREAD flag was specified and spinlocks are not
+implemented for this architecture.
+<p>The DB_HOME or TMPDIR environment variables were set but empty.
+<p>An incorrectly formatted <b>NAME VALUE</b> entry or line was found.
+</dl>
+<p><dl compact>
+<p><dt>ENOSPC<dd>HP-UX only: a previously created Berkeley DB environment for this process still
+exists.
+</dl>
+<p>The DbEnv::open method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv::open method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<p>
+int
+DbEnv::remove(const char *db_home, u_int32_t flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The DbEnv::remove method destroys a Berkeley DB environment, if it is not
+currently in use.  The environment regions, including any backing files,
+are removed.  Any log or database files and the environment directory are
+not removed.
+<p>The <b>db_home</b> argument to DbEnv::remove is described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p>If there are processes that have called <a href="../api_cxx/env_open.html">DbEnv::open</a> without
+calling <a href="../api_cxx/env_close.html">DbEnv::close</a> (i.e., there are processes currently using
+the environment), DbEnv::remove will fail without further action,
+unless the <a href="../api_cxx/env_remove.html#DB_FORCE">DB_FORCE</a> flag is set, in which case
+DbEnv::remove will attempt to remove the environment regardless
+of any processes still using it.
+<p>The result of attempting to forcibly destroy the environment when it is
+in use is unspecified.  Processes using an environment often maintain open
+file descriptors for shared regions within it.  On UNIX systems, the
+environment removal will usually succeed and processes that have already
+joined the region will continue to run in that region without change,
+however processes attempting to join the environment will either fail or
+create new regions.  On other systems (e.g., Windows/NT), where the
+<b>unlink</b>(2) system call will fail if any process has an open
+file descriptor for the file, the region removal will fail.
+<p>Calling DbEnv::remove should not be necessary for most applications,
+as the Berkeley DB environment is cleaned up as part of normal database recovery
+procedures, however, applications may wish to call DbEnv::remove
+as part of application shutdown to free up system resources.
+Specifically, when the <a href="../api_cxx/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag was specified to
+<a href="../api_cxx/env_open.html">DbEnv::open</a>, it may be useful to call DbEnv::remove in order
+to release system shared memory segments that have been allocated.
+<p>In the case of catastrophic or system failure, database recovery must be
+performed (see <a href="../utility/db_recover.html">db_recover</a>), or the <a href="../api_cxx/env_open.html#DB_RECOVER">DB_RECOVER</a> and
+<a href="../api_cxx/env_open.html#DB_RECOVER_FATAL">DB_RECOVER_FATAL</a> flags to <a href="../api_cxx/env_open.html">DbEnv::open</a> must be specified
+when the environment is re-opened.  Alternatively, if recovery is not
+required because no database state is maintained across failures, and
+the <a href="../api_cxx/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag was not specified when the environment
+was created, it is possible to clean up an environment by removing all
+of the files in the environment directory that begin with the string
+prefix "__db", as no backing files are created in any other directory.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_FORCE">DB_FORCE</a><dd>If the <a href="../api_cxx/env_remove.html#DB_FORCE">DB_FORCE</a> flag is set, the environment is removed regardless

+specified when applications were unable to shut down cleanly, and there
+is a risk that an application may have died holding a Berkeley DB lock.)

+</pre></h3>
+<h1>Description</h1>
+<p>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.  For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>The DbEnv::set_cachesize interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/env_open.html">DbEnv::open</a> interface is called.
+<p>The DbEnv::set_cachesize method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<p>The database environment's cache size may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_cachesize", one or more whitespace characters,
+and the three arguments specified to this interface, separated by whitespace
+characters, for example, "set_cachesize 1 500 2".  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+<h1>Description</h1>
+<p>Set the prefix string that appears before error messages issued by Berkeley DB.
+<p>The DbEnv::set_errpfx method does not copy the memory referenced by the
+<b>errpfx</b> argument, rather, it maintains a reference to it.  This
+allows applications to modify the error message prefix at any time,
+without repeatedly calling DbEnv::set_errpfx, but means that the
+memory must be maintained until the handle is closed.
+<p>The DbEnv::set_errpfx interface may be used to configure Berkeley DB at any time
+during the life of the application.

+<h1>Description</h1>
+<p>Some operations performed by the Berkeley DB library can take non-trivial
+amounts of time.  The DbEnv::set_feedback method can be used by
+applications to monitor progress within these operations.
+<p>When an operation is likely to take a long time, Berkeley DB will call the
+specified callback method.  This method must be declared with
+three arguments: the first will be a reference to the enclosing
+environment, the second a flag value, and the third the percent of the
+operation that has been completed, specified as an integer value between
+0 and 100.  It is up to the callback method to display this
+information in an appropriate manner.
+<p>The <b>opcode</b> argument may take on any of the following values:
+<p><dl compact>
+<p><dt><a name="DB_RECOVER">DB_RECOVER</a><dd>The environment is being recovered.
+</dl>
+<p>The DbEnv::set_feedback interface may be used to configure Berkeley DB at any time
+during the life of the application.
+<p>The DbEnv::set_feedback method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<h1>Description</h1>
+<p>Errors can occur in the Berkeley DB library where the only solution is to shut
+down the application and run recovery.  (For example, if Berkeley DB is unable
+to write log records to disk because there is insufficient disk space.)
+In these cases, when the C++ error model has been configured so that the
+individual Berkeley DB methods return error codes (see <a href="../api_cxx/except_class.html">DbException</a> for
+more information), the value <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is returned by Berkeley DB
+methods.
+<p>In these cases, it is also often simpler to shut down the application when
+such errors occur rather than attempting to gracefully return up the stack.
+The DbEnv::set_paniccall method is used to specify a method to be called when
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is about to be returned from a Berkeley DB method.  When
+called, the <b>dbenv</b> argument will be a reference to the current
+environment, and the <b>errval</b> argument is the error value that would
+have been returned to the calling method.
+<p>The DbEnv::set_paniccall interface may be used to configure Berkeley DB at any time
+during the life of the application.
+<p>The DbEnv::set_paniccall method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.

+<p>The DbEnv::set_recovery_init interface may only be used to configure Berkeley DB before

+<h1>Description</h1>
+<p>Page-fault shared regions into memory when initially creating or joining
+a Berkeley DB environment.  In some applications, the expense of page-faulting
+the shared memory regions can affect performance, e.g., when the
+page-fault occurs while holding a lock, other lock requests can convoy
+and overall throughput may decrease.  Setting <b>region_init</b> to a
+non-zero value specifies that shared regions be read or written, as
+appropriate, when the region is joined by the application.  This forces
+the underlying virtual memory and file systems to instantiate both the
+necessary memory and the necessary disk space.  This can also avoid
+out-of-disk space failures later on.
+<p>The DbEnv::set_region_init interface affects the entire application, not a single
+database or database environment.
+<p>While the DbEnv::set_region_init interface may be used to configure Berkeley DB at any time
+during the life of the application, it should normally be called before
+making any calls to the <a href="../api_c/env_create.html">db_env_create</a> or <a href="../api_c/db_create.html">db_create</a> methods.
+<p>The DbEnv::set_region_init method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<p>The database environment's initial behavior with respect to shared memory regions may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_region_init", one or more whitespace characters,
+and the string "1".  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+has expired on any communication with the server, DB_NOSERVER will
+be returned.  If this value is zero, a default timeout is used.
+<p>The <b>sv_timeout</b> argument specifies the number of seconds the server
+should allow a client connection to remain idle before assuming that
+client is gone.  Once that timeout has been reached, the server releases
+all resources associated with that client connection.  Subsequent attempts
+by that client to communicate with the server result in
+DB_NOSERVER_ID indicating that an invalid identifier has been
+given to the server.  This value can be considered a hint to the server.
+The server may alter this value based on its own policies or allowed
+values.  If this value is zero, a default timeout is used.
+<p>The <b>flags</b> parameter is currently unused, and must be set to 0.

+<h1>Description</h1>
+<p>Specify a base segment ID for Berkeley DB environment shared memory regions
+created in system memory on VxWorks or systems supporting X/Open-style
+shared memory interfaces, e.g., UNIX systems supporting
+<b>shmget</b>(2) and related System V IPC interfaces.
+<p>This base segment ID will be used when Berkeley DB shared memory regions are
+first created.  It will be incremented a small integer value each time
+a new shared memory region is created, that is, if the base ID is 35,
+the first shared memory region created will have a segment ID of 35 and
+the next one a segment ID between 36 and 40 or so.  A Berkeley DB environment
+always creates a master shared memory region, plus an additional shared
+memory region for each of the subsystems supported by the environment
+(locking, logging, memory pool and transaction), plus an additional
+shared memory region for each additional memory pool cache that is
+supported.  Already existing regions with the same segment IDs will be
+removed.  See <a href="../ref/env/region.html">Shared Memory Regions</a>
+for more information.
+<p>The intent behind this interface is two-fold: without it, applications
+have no way to ensure that two Berkeley DB applications don't attempt to use
+the same segment IDs when creating different Berkeley DB environments.  In
+addition, by using the same segment IDs each time the environment is
+created, previously created segments will be removed, and the set of
+segments on the system will not grow without bound.
+<p>The DbEnv::set_shm_key interface may only be used to configure Berkeley DB before
+the <a href="../api_cxx/env_open.html">DbEnv::open</a> interface is called.
+<p>The DbEnv::set_shm_key method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<p>The database environment's base segment ID may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_shm_key", one or more whitespace characters,
+and the ID.  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+<h1>Description</h1>
+<p>Specify that test-and-set mutexes should spin <b>tas_spins</b> times
+without blocking.  The value defaults to 1 on uniprocessor systems and
+to 50 times the number of processors on multiprocessor systems.
+<p>The DbEnv::set_tas_spins interface affects the entire application, not a single
+database or database environment.
+<p>While the DbEnv::set_tas_spins interface may be used to configure Berkeley DB at any time
+during the life of the application, it should normally be called before
+making any calls to the <a href="../api_c/env_create.html">db_env_create</a> or <a href="../api_c/db_create.html">db_create</a> methods.
+<p>The DbEnv::set_tas_spins method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<p>The database environment's test-and-set spin count may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_tas_spins", one or more whitespace characters,
+and the number of spins.  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+"set_verbose DB_VERB_CHKPOINT".  Because the <b>DB_CONFIG</b> file is read when the database

+};
+</pre></h3>
+<h1>Description</h1>
+<p>This manual page describes the DbException class and how it is used
+by the various Berkeley DB classes.
+<p>Most methods in the Berkeley DB classes return an int but also throw an
+exception.  This allows for two different error behaviors.  By default,
+the Berkeley DB C++ API is configured to throw an exception whenever a serious
+error occurs.  This generally allows for cleaner logic for transaction
+processing, as a try block can surround a single transaction.
+Alternatively, Berkeley DB can be configured to not throw exceptions, and
+instead have the individual function return an error code, by setting
+the constructor flags for the Db and <a href="../api_cxx/dbenv_class.html">DbEnv</a> objects.
+<p>A DbException object contains an informational string and an errno.
+The errno can be obtained by using <a href="../api_cxx/get_errno.html">DbException::get_errno</a>.
+The informational string can be obtained by using <a href="../api_cxx/what.html">DbException::what</a>.
+<p>We expect in the future that this class will inherit from the standard
+class exception, but certain language implementation bugs currently
+prevent this on some platforms.
+<p>Some methods may return non-zero values without issuing an exception.
+This occurs in situations that are not normally considered an error, but
+when some informational status is returned.  For example, <a href="../api_cxx/db_get.html">Db::get</a>
+returns DB_NOTFOUND when a requested key does not appear in the database.

+case of deadlock.  It must be set to one of possible arguments listed for
+the <a href="../api_cxx/env_set_lk_detect.html">DbEnv::set_lk_detect</a> interface.
+<p>If the <b>aborted</b> parameter is non-NULL, the memory location it

+<p>The DbEnv::lock_detect method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv::lock_detect method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<h1>Description</h1>
+<p>The DbEnv::lock_get method acquires a lock from the lock table, returning
+information about it in
+the <b>lock</b> argument.
+<p>The <b>locker</b> argument specified to DbEnv::lock_get is an unsigned
+32-bit integer quantity.  It represents the entity requesting or releasing
+the lock.
+<p>The <b>flags</b> value must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_LOCK_NOWAIT">DB_LOCK_NOWAIT</a><dd>If a lock cannot be granted because the requested lock conflicts with an
+existing lock, return immediately instead of waiting for the lock to
+become available.
+</dl>
+<p>The <b>obj</b> argument is an untyped byte string that specifies the
+object to be locked or released.
+<p>The <b>mode</b> argument is an index into the environment's lock conflict
+array.  See <a href="../api_cxx/env_set_lk_conflicts.html">DbEnv::set_lk_conflicts</a> and
+<a href="../ref/lock/stdmode.html">Standard Lock Modes</a>
+for a description of that array.
+<p>The DbEnv::lock_get method may
+return or throw an exception encapsulating
+one of the following values:
+<p><dl compact>
+<p><dt><a name="DB_LOCK_NOTGRANTED">DB_LOCK_NOTGRANTED</a><dd>A lock was requested that could not be immediately granted and the
+<b>flags</b> parameter was set to DB_LOCK_NOWAIT.
+</dl>
+<p>Otherwise, the DbEnv::lock_get method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The DbEnv::lock_get method may fail and throw an exception or return a non-zero error for the following conditions:

+<p><dl compact>
+<p><dt>ENOMEM<dd>The maximum number of locks has been reached.
+</dl>
+<p>The DbEnv::lock_get method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.

+<p>The DbEnv::lock_stat method
+creates a statistical structure and copies a pointer to it into a

+<p>Statistical structures are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The lock region statistics are stored in a structure of type
+DB_LOCK_STAT.  The following DB_LOCK_STAT fields will be filled in:
+<p><dl compact>
+<dt>u_int32_t st_lastid;<dd>The last allocated lock ID.

+<a href="../api_cxx/lock_vec.html#DB_LOCK_NOWAIT">DB_LOCK_NOWAIT</a> was set.
+<dt>u_int32_t st_nconflicts;<dd>The total number of locks not immediately available due to conflicts.
+<dt>u_int32_t st_ndeadlocks;<dd>The number of deadlocks detected.

+<h1>Description</h1>
+<p>The DbEnv::lock_vec method atomically obtains and releases one or more locks
+from the lock table.  The DbEnv::lock_vec method is intended to support
+acquisition or trading of multiple locks under one lock table semaphore,
+as is needed for lock coupling or in multigranularity locking for lock
+escalation.
+<p>The <b>locker</b> argument specified to DbEnv::lock_vec is an unsigned
+32-bit integer quantity.  It represents the entity requesting or releasing
+the lock.
+<p>The <b>flags</b> value must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="DB_LOCK_NOWAIT">DB_LOCK_NOWAIT</a><dd>If a lock cannot be immediately granted because the requested lock
+conflicts with an existing lock, return instead of waiting for the lock
+to become available.
+</dl>
+<p>The <b>list</b> array provided to DbEnv::lock_vec is typedef'd as
+DB_LOCKREQ.  A DB_LOCKREQ structure has at least the following fields,
+which must be initialized before calling DbEnv::lock_vec:
+<p><dl compact>
+<p><dt>lockop_t <a name="op">op</a>;<dd>The operation to be performed, which must be set to one of the

+<p><dl compact>
+<p><dt><a name="DB_LOCK_GET">DB_LOCK_GET</a><dd>Get a lock, as defined by the values of <b>locker</b>, <b>obj</b>,
+and <b>mode</b>.  Upon return from DbEnv::lock_vec, if the
+<b>lock</b> field is non-NULL, a reference to the acquired lock is
+stored there.  (This reference is invalidated by any call to
+DbEnv::lock_vec or <a href="../api_cxx/lock_put.html">DbLock::put</a> that releases the lock.)
+<p><dt><a name="DB_LOCK_PUT">DB_LOCK_PUT</a><dd>The lock referenced by the contents of the <b>lock</b> field is released.
+<p><dt><a name="DB_LOCK_PUT_ALL">DB_LOCK_PUT_ALL</a><dd>All locks held by the <b>locker</b> are released.  (Any locks acquired
+as a part of the current call to DbEnv::lock_vec that appear after the
+DB_LOCK_PUT_ALL entry are not considered for this
+operation).
+<p><dt><a name="DB_LOCK_PUT_OBJ">DB_LOCK_PUT_OBJ</a><dd>All locks held on the object <b>obj</b> are released.  The <b>mode</b>
+and <b>locker</b> parameters are ignored.  Note that any locks acquired

+};
+int
+DbEnv::log_archive(char *(*listp)[],
+    u_int32_t flags, db_malloc_fcn_type db_malloc);
+</pre></h3>
+<h1>Description</h1>
+<p>The DbEnv::log_archive method
+creates a NULL-terminated array of log or database file names and copies
+a pointer to them into the user-specified memory location <b>listp</b>.
+<p>By default, DbEnv::log_archive returns the names of all of the log files
+that are no longer in use (e.g., no longer involved in active transactions),
+and that may safely be archived for catastrophic recovery and then removed
+from the system.  If there were no file names to return, the memory location
+referenced by <b>listp</b> will be set to NULL.
+<p>Arrays of log file names are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_ARCH_ABS">DB_ARCH_ABS</a><dd>All pathnames are returned as absolute pathnames,
+instead of relative to the database home directory.
+<p><dt><a name="DB_ARCH_DATA">DB_ARCH_DATA</a><dd>Return the database files that need to be archived in order to recover
+the database from catastrophic failure.  If any of the database files
+have not been accessed during the lifetime of the current log files,
+DbEnv::log_archive will not include them in this list.  It is also
+possible that some of the files referenced in the log have since been
+deleted from the system.
+<p><dt><a name="DB_ARCH_LOG">DB_ARCH_LOG</a><dd>Return all the log file names regardless of whether or not they are in
+use.
+</dl>
+<p>The DB_ARCH_DATA and DB_ARCH_LOG flags are mutually
+exclusive.
+<p>See the <a href="../utility/db_archive.html">db_archive</a> manual page for more information on database
+archival procedures.
+<p>The DbEnv::log_archive method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Bugs</h1>
+<p>In a threaded application (i.e., one where the environment was created
+with the DB_THREAD flag specified), calling DbEnv::log_archive with the
+DB_ARCH_DATA flag will fail, returning EINVAL.  To work around this
+problem, re-open the log explicitly without specifying DB_THREAD.  This
+restriction is expected to be removed in a future version of Berkeley DB.
+<h1>Errors</h1>
+<p>The DbEnv::log_archive method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The log was corrupted.
+</dl>
+<p>The DbEnv::log_archive method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv::log_archive method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
+in the same way.

+</pre></h3>
+<h1>Description</h1>
+<p>The DbMpoolFile::open method opens a file in the pool specified by the
+<a href="../api_cxx/dbenv_class.html">DbEnv</a> <b>env</b>, copying the <a href="../api_cxx/mempfile_class.html">DbMpoolFile</a> pointer
+representing it into the memory location referenced by <b>mpf</b>.
+<p>The <b>file</b> argument is the name of the file to be opened.
+If <b>file</b> is NULL, a private file is created that cannot be
+shared with any other process (although it may be shared with
+other threads).
+<p>The <b>flags</b> and <b>mode</b> arguments specify how files will be opened
+and/or created if they do not already exist.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="DB_CREATE">DB_CREATE</a><dd>Create any underlying files, as necessary.  If the files do not already
+exist and the DB_CREATE flag is not specified, the call will fail.
+<p><dt><a name="DB_NOMMAP">DB_NOMMAP</a><dd>Always copy this file into the local cache instead of potentially mapping
+it into process memory (see the description of the
+<a href="../api_cxx/env_set_mp_mmapsize.html">DbEnv::set_mp_mmapsize</a> method for further information).
+<p><dt><a name="DB_RDONLY">DB_RDONLY</a><dd>Open any underlying files for reading only.  Any attempt to write the file
+using the pool functions will fail, regardless of the actual permissions
+of the file.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by function DbMpoolFile::open
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>The <b>pagesize</b> argument is the size, in bytes, of the unit of transfer
+between the application and the pool, although it is not necessarily the
+unit of transfer between the pool and the source file.
+<p>Files opened in the pool may be further configured based on the
+<b>finfop</b> argument to DbMpoolFile::open (which is a pointer to a
+structure of type DB_MPOOL_FINFO).  No references to the <b>finfop</b>
+structure are maintained by Berkeley DB, so it may be discarded when the
+DbMpoolFile::open function returns.  In order to ensure compatibility
+with future releases of Berkeley DB, all fields of the DB_MPOOL_FINFO structure
+that are not explicitly set should be initialized to 0 before the first
+time the structure is used.  Do this by declaring the structure external
+or static, or by calling the C library routine <b>bzero</b>(3) or
+<b>memset</b>(3).
+<p>The fields of the DB_MPOOL_FINFO structure used by DbMpoolFile::open are
+described below.  If <b>finfop</b> is NULL or any of its fields are
+set to their default value, defaults appropriate for the system are used.
+<p><dl compact>
+<p><dt>int <a name="ftype">ftype</a>;<dd>The <b>ftype</b> field should be the same as a <b>ftype</b> argument
+previously specified to the <a href="../api_cxx/memp_register.html">DbEnv::memp_register</a> function, unless no
+input or output processing of the file's pages are necessary, in which
+case it should be 0.  (See the description of the <a href="../api_cxx/memp_register.html">DbEnv::memp_register</a>
+function for more information.)
+<p><dt>DBT *<a name="pgcookie">pgcookie</a>;<dd>The <b>pgcookie</b> field contains the byte string that is passed to the
+<b>pgin</b> and <b>pgout</b> functions for this file, if any.  If no
+<b>pgin</b> or <b>pgout</b> functions are specified, the
+<b>pgcookie</b> field should be NULL.  (See the description of the
+<a href="../api_cxx/memp_register.html">DbEnv::memp_register</a> function for more information.)
+<p><dt>u_int8_t *<a name="fileid">fileid</a>;<dd>The <b>fileid</b> field is a unique identifier for the file.  If the
+<b>fileid</b> field is non-NULL, it must reference a DB_FILE_ID_LEN
+length array of bytes that will be used to uniquely identify the file.
+<p>The mpool functions must be able to uniquely identify files in order that
+multiple processes wanting to share a file will correctly identify it in
+the pool.
+<p>On most UNIX/POSIX systems, the <b>fileid</b> field will not need to be
+set and the mpool functions will simply use the file's device and inode
+numbers for this purpose.  On Windows systems, the mpool functions use
+the values returned by GetFileInformationByHandle() by default -- these
+values are known to be constant between processes and over reboot in the
+case of NTFS (where they are the NTFS MFT indexes).
+<p>On other filesystems, (e.g., FAT or NFS) these default values are not
+necessarily unique between processes or across system reboots.
+<b>Applications wanting to maintain a shared memory buffer pool
+between processes or across system reboots, where the pool contains pages
+from files stored on such filesystems, must specify a unique file
+identifier to the DbMpoolFile::open call and each process opening or
+registering the file must provide the same unique identifier.</b>
+<p>This should not be necessary for most applications.  Specifically, it is
+not necessary if the memory pool is not shared between processes and is
+re-instantiated after each system reboot, or the application is using the
+Berkeley DB access methods instead of calling the pool functions explicitly, or
+the files in the memory pool are stored on filesystems where the default
+values as described above are invariant between process and across system
+reboots.
+<p><dt>int32_t <a name="lsn_offset">lsn_offset</a>;<dd>The <b>lsn_offset</b> field is the zero-based byte offset in the page of
+the page's log sequence number (LSN), or -1 if no LSN offset is specified.
+(See the description of the <a href="../api_cxx/memp_sync.html">DbEnv::memp_sync</a> function for more
+information.)
+<p><dt>u_int32_t <a name="clear_len">clear_len</a>;<dd>The <b>clear_len</b> field is the number of initial bytes in a page
+that should be set to zero when the page is created as a result of the
+DB_MPOOL_CREATE or DB_MPOOL_NEW flags being specified to <a href="../api_cxx/memp_fget.html">DbMpoolFile::get</a>.
+If <b>finfop</b> is NULL or <b>clear_len</b> is 0, the entire page is
+cleared.
+</dl>
+<p>The DbMpoolFile::open method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The DbMpoolFile::open method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.

+<h1>Description</h1>
+<p>The DbEnv::memp_register method registers page-in and page-out
+functions for files of type <b>ftype</b> in the specified pool.
+<p>If the <b>pgin_fcn</b> function is non-NULL, it is called each time
+a page is read into the memory pool from a file of type <b>ftype</b>, or
+a page is created for a file of type <b>ftype</b> (see the
+DB_MPOOL_CREATE flag for the <a href="../api_cxx/memp_fget.html">DbMpoolFile::get</a> method).
+<p>If the <b>pgout_fcn</b> function is non-NULL, it is called each time
+a page is written to a file of type <b>ftype</b>.
+<p>Both the <b>pgin_fcn</b> and <b>pgout_fcn</b> functions are called with
+a reference to the current environment, the page number, a pointer to the
+page being read or written, and any argument <b>pgcookie</b> that was
+specified to the <a href="../api_cxx/memp_fopen.html">DbMpoolFile::open</a> function when the file was opened.
+The <b>pgin_fcn</b> and <b>pgout_fcn</b> functions should return 0 on
+success, and an applicable non-zero <b>errno</b> value on failure, in
+which case the shared memory pool interface routine (and, by extension,
+any Berkeley DB library function) calling it will also fail, returning that
+<b>errno</b> value.
+<p>The purpose of the DbEnv::memp_register function is to support processing
+when pages are entered into, or flushed from, the pool.  A file type must
+be specified to make it possible for unrelated threads or processes, that
+are sharing a pool, to evict each other's pages from the pool.
+Applications should call DbEnv::memp_register, during initialization,
+for each type of file requiring input or output processing that will be
+sharing the underlying pool.  (No registry is necessary for the standard
+Berkeley DB access method types, as <a href="../api_cxx/db_open.html">Db::open</a> registers them
+separately.)
+<p>If a thread or process does not call DbEnv::memp_register for a file
+type, it is impossible for it to evict pages for any file requiring input
+or output processing from the pool.  For this reason,
+DbEnv::memp_register should always be called by each application sharing
+a pool for each type of file included in the pool, regardless of whether
+or not the application itself uses files of that type.
+<p>There are no standard values for <b>ftype</b>, <b>pgin_fcn</b>,
+<b>pgout_fcn</b> and <b>pgcookie</b>, except that the <b>ftype</b>
+value for a file must be a non-zero positive number, as negative numbers
+are reserved for internal use by the Berkeley DB library.  For this reason,
+applications sharing a pool must coordinate their values amongst
+themselves.
+<p>The DbEnv::memp_register method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The DbEnv::memp_register method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv::memp_register method may fail and either

+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<p>The DbEnv::memp_stat method method creates statistical structures and copies
+pointers to them into user-specified memory locations.  The statistics
+include the number of files participating in the pool, the active pages
+in the pool, and information as to how effective the cache has been.
+<p>Statistical structures are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>If <b>gsp</b> is non-NULL, the global statistics for the memory pool
+<b>mp</b> are copied into the memory location it references.  The
+global statistics are stored in a structure of type DB_MPOOL_STAT.

+<h3><pre>
+#include &lt;db_cxx.h&gt;
+<p>
+int
+DbEnv::memp_sync(DbLsn *lsn);
+</pre></h3>
+<h1>Description</h1>
+<p>The DbEnv::memp_sync method ensures that any modified pages in the pool with
+log sequence numbers less than the <b>lsn</b> argument are written to
+disk.  If <b>lsn</b> is NULL all modified pages in the pool are
+flushed.
+<p>The primary purpose of the DbEnv::memp_sync function is to enable a
+transaction manager to ensure, as part of a checkpoint, that all pages
+modified by a certain time have been written to disk.  Pages in the pool
+that cannot be written back to disk immediately (e.g., that are currently
+pinned) are written to disk as soon as it is possible to do so.  The
+expected behavior of the Berkeley DB or other transaction subsystem is to call
+the DbEnv::memp_sync function and then, if the return indicates that some
+pages could not be written immediately, to wait briefly and retry again
+with the same log sequence number until the DbEnv::memp_sync function
+returns that all pages have been written.
+<p>To support the DbEnv::memp_sync functionality, it is necessary that the
+pool functions know the location of the log sequence number on the page
+for each file type.  This location should be specified when the file is
+opened using the <a href="../api_cxx/memp_fopen.html">DbMpoolFile::open</a> function.  It is not required that
+the log sequence number be aligned on the page in any way.
+<p>The DbEnv::memp_sync method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, 0 on success, and returns <a href="../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> if there were pages which need to be
+written but which DbEnv::memp_sync was unable to write immediately.
+In addition, if DbEnv::memp_sync returns success, the value of
+<b>lsn</b> will be overwritten with the largest log sequence number
+from any page which was written by DbEnv::memp_sync to satisfy this
+request.
+<h1>Errors</h1>
+<p>The DbEnv::memp_sync method may fail and throw an exception or return a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The DbEnv::memp_sync function was called without logging having been
+initialized in the environment.
+</dl>
+<p>The DbEnv::memp_sync method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv::memp_sync method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<p>This manual page describes the specific details of the DbMpoolFile
+class.
+<p>The <a href="../api_cxx/dbenv_class.html">DbEnv</a> memory pool methods and the DbMpoolFile class
+are the library interface that provide general-purpose, page-oriented
+buffer management of one or more files.  While designed to work with the
+other Db classes, they are also useful for more general purposes.
+The memory pools are referred to in this document as simply <i>pools</i>.
+<p>Pools may be shared between processes.  Pools are usually filled by pages
+from one or more files.  Pages in the pool are replaced in LRU
+(least-recently-used) order, with each new page replacing the page that
+has been unused the longest.  Pages retrieved from the pool using
+<a href="../api_cxx/memp_fget.html">DbMpoolFile::get</a> are <i>pinned</i> in the pool until they are
+returned to the control of the buffer pool using the <a href="../api_cxx/memp_fput.html">DbMpoolFile::put</a>

+<p>
+int
+DbTxn::abort();
+</pre></h3>
+<h1>Description</h1>
+<p>The DbTxn::abort method causes an abnormal termination of the
+transaction.  The log is played backwards and any necessary recovery
+operations are initiated through the <b>recover</b> function specified
+to <a href="../api_cxx/env_open.html">DbEnv::open</a>.  After the log processing is completed, all locks
+held by the transaction are released.  As is the case for
+<a href="../api_cxx/txn_commit.html">DbTxn::commit</a>, applications that require strict two-phase locking
+should not explicitly release any locks.
+<p>In the case of nested transactions, aborting a parent transaction causes
+all children (unresolved or not) of the parent transaction to be aborted.
+<p>Once the DbTxn::abort method returns, the <a href="../api_cxx/txn_class.html">DbTxn</a> handle may not
+be accessed again.
+<p>The DbTxn::abort method either returns a non-zero error value or throws an exception that

+<h1>Description</h1>
+<p>This manual page describes the specific details of the DbTxn class.
+<p>The <a href="../api_cxx/dbenv_class.html">DbEnv</a> transaction methods and the DbTxn class provide
+transaction semantics.  Full transaction support is provided by a
+collection of modules that provide interfaces to the services required
+for transaction processing.  These services are recovery, concurrency
+control and the management of shared data.
+<p>Transaction semantics can be applied to the access methods described in
+Db through method call parameters.
+<p>The model intended for transactional use (and the one that is used by
+the access methods) is write-ahead logging to record both before- and
+after-images.  Locking follows a two-phase protocol, with all locks being
+released at transaction commit.

+<h1>Description</h1>
+<p>The DbTxn::prepare method initiates the beginning of a two-phase commit.
+<p>In a distributed transaction environment, Berkeley DB can be used as a local
+transaction manager.  In this case, the distributed transaction manager
+must send <i>prepare</i> messages to each local manager.  The local
+manager must then issue a DbTxn::prepare and await its successful
+return before responding to the distributed transaction manager.  Only
+after the distributed transaction manager receives successful responses
+from all of its <i>prepare</i> messages should it issue any
+<i>commit</i> messages.
+<p>In the case of nested transactions, preparing a parent transaction
+causes all unresolved children of the parent transaction to be prepared.
+<p>The DbTxn::prepare method either returns a non-zero error value or throws an exception that
+encapsulates a non-zero error value on failure, and returns 0 on success.
+<h1>Errors</h1>
+<p>The DbTxn::prepare method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbTxn::prepare method may fail and either
+return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
+<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail

+<h1>Description</h1>
+<p>The DbEnv::txn_stat method
+creates a statistical structure and copies a pointer to it into a

+<p>Statistical structures are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The transaction region statistics are stored in a structure of type
+DB_TXN_STAT.  The following DB_TXN_STAT fields will be filled in:
+<p><dl compact>
+<dt><a href="../api_cxx/lsn_class.html">DbLsn</a> st_last_ckp;<dd>The LSN of the last checkpoint.

+<dt>time_t st_time_ckp;<dd>The time the last completed checkpoint finished (as the number of seconds
+since the Epoch, returned by the IEEE/ANSI Std 1003.1 (POSIX) <b>time</b> interface).
+<dt>u_int32_t st_last_txnid;<dd>The last transaction ID allocated.
+<dt>u_int32_t st_maxtxns;<dd>The maximum number of active transactions possible.
+<dt>u_int32_t st_nactive;<dd>The number of transactions that are currently active.

+obtaining the region lock.
+<dt>u_int32_t st_region_nowait;<dd>The number of times that a thread of control was able to obtain
+the region lock without waiting.
+<dt>DB_TXN_ACTIVE * st_txnarray;<dd>A pointer to an array of <b>st_nactive</b> DB_TXN_ACTIVE structures,

+<h1>Description</h1>
+<p>The Db.close method flushes any cached database information to disk,
+closes any open cursors, frees any allocated resources, and closes any
+underlying files.  Since key/data pairs are cached in memory, failing to
+sync the file with the Db.close or <a href="../api_java/db_sync.html">Db.sync</a> method may result
+in inconsistent or lost information.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="Db.DB_NOSYNC">Db.DB_NOSYNC</a><dd>Do not flush cached information to disk.
+<p>The <a href="../api_java/db_close.html#DB_NOSYNC">Db.DB_NOSYNC</a> flag is a dangerous option.  It should only be set
+if the application is doing logging (with transactions) so that the
+database is recoverable after a system or application crash, or if the
+database is always generated from scratch after any system or application
+crash.
+<p><b>It is important to understand that flushing cached information to disk
+only minimizes the window of opportunity for corrupted data.</b>
+While unlikely, it is possible for database corruption to happen if a
+system or application crash occurs while writing data to the database.
+To ensure that database corruption never occurs, applications must either:
+use transactions and logging with automatic recovery, use logging and
+application-specific recovery, or edit a copy of the database,
+and, once all applications using the database have successfully called
+Db.close, atomically replace the original database with the
+updated copy.
+</dl>
+<p>When multiple threads are using the Berkeley DB handle concurrently, only a single
+thread may call the Db.close method.
+<p>Once Db.close has been called, regardless of its return, the
+<a href="../api_java/db_class.html">Db</a> handle may not be accessed again.
+        <a name="3"><!--meow--></a>    
+<p>The Db.close method throws an exception that encapsulates a non-zero error value on
+failure, and returns <a href="../api_c/memp_fsync.html#DB_INCOMPLETE">Db.DB_INCOMPLETE</a> if the underlying database still has
+dirty pages in the cache.  (The only reason to return
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">Db.DB_INCOMPLETE</a> is if another thread of control was writing pages
+in the underlying database file at the same time as the
+Db.close method was called.  For this reason, a return of
+<a href="../api_c/memp_fsync.html#DB_INCOMPLETE">Db.DB_INCOMPLETE</a> can normally be ignored, or, in cases where it is
+a possible return value, the <a href="../api_java/db_close.html#DB_NOSYNC">Db.DB_NOSYNC</a> option should probably
+have been specified.)
+<p>The Db.close method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The Db.close method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db.close method may fail and throw

+<h1>Description</h1>
+<p>The Db.get method retrieves key/data pairs from the database.  The
+byte array
+and length of the data associated with the specified <b>key</b> are
+returned in the structure referenced by <b>data</b>.
+<p>In the presence of duplicate key values, Db.get will return the
+first data item for the designated key.  Duplicates are sorted by insert
+order except where this order has been overridden by cursor operations.
+<b>Retrieval of duplicates requires the use of cursor operations.</b>
+See <a href="../api_java/dbc_get.html">Dbc.get</a> for details.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_java/txn_begin.html">DbEnv.txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="Db.DB_CONSUME">Db.DB_CONSUME</a><dd>Return the record number and data from the available record closest to
+the head of the queue and delete the record.  The cursor will be
+positioned on the deleted record.  The record number will be returned
+in <b>key</b> as described in <a href="../api_java/dbt_class.html">Dbt</a>.  The data will be returned
+in the <b>data</b> parameter.  A record is available if it is not
+deleted and is not currently locked.  The underlying database must be
+of type Queue for Db.DB_CONSUME to be specified.
+<p><dt><a name="Db.DB_CONSUME_WAIT">Db.DB_CONSUME_WAIT</a><dd>The Db.DB_CONSUME_WAIT flag is the same as the Db.DB_CONSUME
+flag except that if the Queue database is empty, the thread of control
+will wait until there is data in the queue before returning.  The
+underlying database must be of type Queue for Db.DB_CONSUME_WAIT
+to be specified.
+<p><dt><a name="Db.DB_GET_BOTH">Db.DB_GET_BOTH</a><dd>Retrieve the key/data pair only if both the key and data match the

+Upon return, both the <b>key</b> and <b>data</b> items will have been
+filled in, not just the data item as is done for all other uses of the
+Db.get method.
+<p>The <b>data</b> field of the specified <b>key</b>
+must be a byte array large enough to hold a logical record
+number (i.e., an int).
+This record number determines the record to be retrieved.
+<p>For Db.DB_SET_RECNO to be specified, the underlying database must be
+of type Btree and it must have been created with the DB_RECNUM flag.
+</dl>
+<p>In addition, the following flag may be set by bitwise inclusively <b>OR</b>'ing it into the
+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="Db.DB_RMW">Db.DB_RMW</a><dd>Acquire write locks instead of read locks when doing the retrieval.
+Setting this flag may decrease the likelihood of deadlock during a
+read-modify-write cycle by immediately acquiring the write lock during
+the read part of the cycle so that another thread of control acquiring
+a read lock for the same item, in its own read-modify-write cycle, will
+not result in deadlock.
+<p>As the Db.get interface will not hold locks across
+Berkeley DB interface calls in non-transactional environments, the
+<a href="../api_java/dbc_get.html#DB_RMW">Db.DB_RMW</a> flag to the Db.get call is only meaningful in
+the presence of transactions.
+</dl>
+<p>If the database is a Queue or Recno database and the requested key exists,
+but was never explicitly created by the application or was later deleted,
+the Db.get method returns <a href="../ref/program/errorret.html#DB_KEYEMPTY">Db.DB_KEYEMPTY</a>.
+<p>Otherwise, if the requested key is not in the database, the
+Db.get function returns <a href="../ref/program/errorret.html#DB_NOTFOUND">Db.DB_NOTFOUND</a>.
+<p>Otherwise, the Db.get method throws an exception that encapsulates a non-zero error value on

+<h3><pre>
+import com.sleepycat.db.*;
+<p>
+public Dbc join(Dbc curslist[], int flags)
+	throws DbException;
+</pre></h3>
+<h1>Description</h1>
+<p>The Db.join method creates a specialized cursor for use in performing
+joins on secondary indexes.  For information on how to organize your data
+to use this functionality, see <a href="../ref/am/join.html">Logical
+join</a>.
+<p>The <b>primary</b> argument contains the <a href="../api_java/db_class.html">Db</a> handle of the primary
+database, which is keyed by the data values found in entries in the
+<b>curslist</b>.
+<p>The <b>curslist</b> argument contains a null terminated array of cursors.
+Each cursor must have been initialized to reference the key on which the
+underlying database should be joined.  Typically, this initialization is done
+by a <a href="../api_java/dbc_get.html">Dbc.get</a> call with the <a href="../api_java/dbc_get.html#DB_SET">Db.DB_SET</a> flag specified.  Once the
+cursors have been passed as part of a <b>curslist</b>, they should not
+be accessed or modified until the newly created join cursor has been closed,
+or else inconsistent results may be returned.
+<p>Joined values are retrieved by doing a sequential iteration over the first
+cursor in the <b>curslist</b> argument, and a nested iteration over each
+secondary cursor in the order they are specified in the <b>curslist</b>
+argument.  This requires database traversals to search for the current
+datum in all the cursors after the first.  For this reason, the best join
+performance normally results from sorting the cursors from the one that
+references the least number of data items to the one that references the
+most.  By default, Db.join does this sort on behalf of its caller.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="Db.DB_JOIN_NOSORT">Db.DB_JOIN_NOSORT</a><dd>Do not sort the cursors based on the number of data items they reference.
+If the data are structured such that cursors with many data items also
+share many common elements, higher performance will result from listing
+those cursors before cursors with fewer data items, that is, a sort order
+other than the default.  The Db.DB_JOIN_NOSORT flag permits
+applications to perform join optimization prior to calling Db.join.
+</dl>
+<p>The returned cursor has the standard cursor functions:
+<p><dl compact>
+<p><dt><a href="../api_java/dbc_get.html">Dbc.get</a><dd>Iterates over the values associated with the keys to which each item in
+<b>curslist</b> has been initialized.  Any data value which appears in
+all items specified by the <b>curslist</b> argument is then used as a
+key into the <b>primary</b>, and the key/data pair found in the
+<b>primary</b> is returned.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="Db.DB_JOIN_ITEM">Db.DB_JOIN_ITEM</a><dd>Do not use the data value found in all of the cursors as a lookup
+key for the <b>primary</b>, but simply return it in the key parameter
+instead.  The data parameter is left unchanged.
+</dl>
+<p>In addition, the following flag may be set by bitwise inclusively <b>OR</b>'ing it into the
+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="Db.DB_RMW">Db.DB_RMW</a><dd>Acquire write locks instead of read locks when doing the retrieval.
+Setting this flag may decrease the likelihood of deadlock during a
+read-modify-write cycle by immediately acquiring the write lock during
+the read part of the cycle so that another thread of control acquiring
+a read lock for the same item, in its own read-modify-write cycle, will
+not result in deadlock.
+</dl>
+<p><dt><a href="../api_java/dbc_put.html">Dbc.put</a><dd>Returns EINVAL.
+<p><dt><a href="../api_java/dbc_del.html">Dbc.del</a><dd>Returns EINVAL.
+<p><dt><a href="../api_java/dbc_close.html">Dbc.close</a><dd>Close the returned cursor and release all resources.  (Closing the cursors
+in <b>curslist</b> is the responsibility of the caller.)
+</dl>
+<p>For the returned join cursor to be used in a transaction protected manner,
+the cursors listed in <b>curslist</b> must have been created within the
+context of the same transaction.
+<p>The Db.join method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The Db.join method may fail and throw an exception encapsulating a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The <a href="../api_java/dbc_put.html">Dbc.put</a> or <a href="../api_java/dbc_del.html">Dbc.del</a> functions were called.
+</dl>
+<p>The Db.join method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db.join method may fail and throw
+a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls

+<p>The information is returned in the <b>key_range</b> argument, which
+contains three elements of type double, <b>less</b>, <b>equal</b> and
+<b>greater</b>.  Values are in the range of 0 to 1, e.g., if the field
+<b>less</b> is 0.05, that indicates that 5% of the keys in the database
+are less than the key argument.  The value for <b>equal</b> will be zero
+if there is no matching key and non-zero otherwise.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from

+	throws DbException, FileNotFoundException;
+</pre></h3>
+<h1>Description</h1>
+<p>The currently supported Berkeley DB file formats (or <i>access methods</i>)
+are Btree, Hash, Queue and Recno.  The Btree format is a representation
+of a sorted, balanced tree structure.  The Hash format is an extensible,
+dynamic hashing scheme.  The Queue format supports fast access to
+fixed-length records accessed by sequentially or logical record number.
+The Recno format supports fixed- or variable-length records, accessed
+sequentially or by logical record number, and optionally retrieved from
+a flat text file.
+<p>Storage and retrieval for the Berkeley DB access methods are based on key/data
+pairs, see <a href="../api_java/dbt_class.html">Dbt</a> for more information.
+<p>The Db.open interface opens the database represented by the
+<b>file</b> and <b>database</b> arguments for both reading and writing.
+The <b>file</b> argument is used as the name of a physical file on disk
+that will be used to back the database.  The <b>database</b> argument is
+optional and allows applications to have multiple logical databases in a
+single physical file.  While no <b>database</b> argument needs to be
+specified, it is an error to attempt to open a second database in a
+<b>file</b> that was not initially created using a <b>database</b> name.
+In-memory databases never intended to be preserved on disk may
+be created by setting both the <b>file</b> and <b>database</b> arguments
+to null.  Note that in-memory databases can only ever be shared by
+sharing the single database handle that created them, in circumstances
+where doing so is safe.
+<p>The <b>type</b> argument is of type int
+and must be set to one of Db.DB_BTREE, Db.DB_HASH,
+Db.DB_QUEUE, Db.DB_RECNO or Db.DB_UNKNOWN, except
+that databases of type Db.DB_QUEUE are restricted to one per
+<b>file</b>.  If <b>type</b> is Db.DB_UNKNOWN, the database must
+already exist and Db.open will automatically determine its type.
+The <a href="../api_java/db_get_type.html">Db.get_type</a> method may be used to determine the underlying type of
+databases opened using Db.DB_UNKNOWN.
+<p>The <b>flags</b> and <b>mode</b> arguments specify how files will be opened
+and/or created if they do not already exist.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="Db.DB_CREATE">Db.DB_CREATE</a><dd>Create any underlying files, as necessary.  If the files do not already
+exist and the DB_CREATE flag is not specified, the call will fail.
+<p><dt><a name="Db.DB_EXCL">Db.DB_EXCL</a><dd>Return an error if the file already exists.  Underlying filesystem
+primitives are used to implement this flag.  For this reason it is only
+applicable to the physical file and cannot be used to test if a database
+in a file already exists.
+<p>The Db.DB_EXCL flag is only meaningful when specified with the
+Db.DB_CREATE flag.
+<p><dt><a name="Db.DB_NOMMAP">Db.DB_NOMMAP</a><dd>Do not map this database into process memory (see the description of the
+<a href="../api_java/env_set_mp_mmapsize.html">DbEnv.set_mp_mmapsize</a> method for further information).
+<p><dt><a name="Db.DB_RDONLY">Db.DB_RDONLY</a><dd>Open the database for reading only.  Any attempt to modify items in the
+database will fail regardless of the actual permissions of any underlying
+files.
+<p><dt><a name="Db.DB_THREAD">Db.DB_THREAD</a><dd>Cause the <a href="../api_java/db_class.html">Db</a> handle returned by Db.open to be
+<i>free-threaded</i>, that is, useable by multiple threads within a
+single address space.
+<p>Threading is always assumed in the Java API, so no special flags are
+required, and Berkeley DB functions will always behave as if the
+<a href="../api_java/env_open.html#DB_THREAD">Db.DB_THREAD</a> flag was specified.
+<p><dt><a name="Db.DB_TRUNCATE">Db.DB_TRUNCATE</a><dd>Physically truncate the underlying file, discarding all previous databases
+it might have held.  Underlying filesystem primitives are used to
+implement this flag.  For this reason it is only applicable to the
+physical file and cannot be used to discard databases within a file.
+<p>The Db.DB_TRUNCATE flag cannot be transaction protected, and it is
+an error to specify it in a transaction protected environment.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by the access methods
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>Calling Db.open is a reasonably expensive operation, and
+maintaining a set of open databases will normally be preferable to
+repeatedly open and closing the database for each new query.
+<p>The Db.open method throws an exception that encapsulates a non-zero error value on
+failure.

+<a href="../api_java/env_open.html">DbEnv.open</a> the environment variable <b>DB_HOME</b> may be used

+public int put(DbTxn txnid, Dbt key, Dbt data, int flags)
+	throws DbException;
+</pre></h3>
+<h1>Description</h1>
+<p>The Db.put method stores key/data pairs in the database.  The default
+behavior of the Db.put function is to enter the new key/data
+pair, replacing any previously existing key if duplicates are disallowed,
+or adding a duplicate data item if duplicates are allowed.  If the database
+supports duplicates, the Db.put method adds the new data value at the
+end of the duplicate set.  If the database supports sorted duplicates,
+the new data value is inserted at the correct sorted location.
+<p>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction ID returned from
+<a href="../api_java/txn_begin.html">DbEnv.txn_begin</a>, otherwise, NULL.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="Db.DB_APPEND">Db.DB_APPEND</a><dd>Append the key/data pair to the end of the database.  For the
+Db.DB_APPEND flag to be specified, the underlying database must be
+a Queue or Recno database.  The record number allocated to the record is
+returned in the specified <b>key</b>.
+<p>There is a minor behavioral difference between the Recno and Queue access
+methods for the Db.DB_APPEND flag.  If a transaction enclosing a
+Db.put operation with the Db.DB_APPEND flag aborts, the
+record number may be decremented (and later re-allocated by a subsequent
+Db.DB_APPEND operation) by the Recno access method, but will not be
+decremented or re-allocated by the Queue access method.
+<p><dt><a name="Db.DB_NODUPDATA">Db.DB_NODUPDATA</a><dd>In the case of the Btree and Hash access methods, enter the new key/data
+pair only if it does not already appear in the database.  If the
+key/data pair already appears in the database, <a href="../api_java/dbc_put.html#DB_KEYEXIST">Db.DB_KEYEXIST</a> is
+returned.  The Db.DB_NODUPDATA flag may only be specified if the
+underlying database has been configured to support sorted duplicates.
+<p>The Db.DB_NODUPDATA flag may not be specified to the Queue or Recno
+access methods.
+<p><dt><a name="Db.DB_NOOVERWRITE">Db.DB_NOOVERWRITE</a><dd>Enter the new key/data pair only if the key does not already appear in
+the database.  If the key already appears in the database,
+<a href="../api_java/dbc_put.html#DB_KEYEXIST">Db.DB_KEYEXIST</a> is returned.  Even if the database allows duplicates,
+a call to Db.put with the Db.DB_NOOVERWRITE flag set will
+fail if the key already exists in the database.
+</dl>
+<p>Otherwise, the Db.put method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The Db.put method may fail and throw an exception encapsulating a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EACCES<dd>An attempt was made to modify a read-only database.

+<p>The comparison function must return an integer value less than, equal
+to, or greater than zero if the first key argument is considered to be
+respectively less than, equal to, or greater than the second key
+argument.  In addition, the comparison function must cause the keys in
+the database to be <i>well-ordered</i>.  The comparison function
+must correctly handle any key values used by the application (possibly
+including zero-length keys).  In addition, when Btree key prefix
+comparison is being performed (see <a href="../api_java/db_set_bt_prefix.html">Db.set_bt_prefix</a> for more
+information), the comparison routine may be passed a prefix of any
+database key.  The <b>data</b> and <b>size</b> fields of the
+<a href="../api_java/dbt_class.html">Dbt</a> are the only fields that may be used for the purposes of
+this comparison.
+<p>If no comparison function is specified, the keys are compared lexically,

+<h1>Description</h1>
+<p>Set the Btree prefix function.  The prefix function must return the
+number of bytes of the second key argument that would be required by
+the Btree key comparison function to determine the second key argument's
+ordering relationship with respect to the first key argument.  If the
+two keys are equal, the key length should be returned.  The prefix
+function must correctly handle any key values used by the application
+(possibly including zero-length keys).  The <b>data</b> and
+<b>size</b> fields of the <a href="../api_java/dbt_class.html">Dbt</a> are the only fields that may be
+used for the purposes of this determination.
+<p>The prefix function is used to determine the amount by which keys stored
+on the Btree internal pages can be safely truncated without losing their
+uniqueness.  See the <a href="../ref/am_conf/bt_prefix.html">Btree
+prefix comparison</a> section of the Reference Guide for more details about
+how this works.  The usefulness of this is data dependent, but in some
+data sets can produce significantly reduced tree sizes and search times.
+<p>If no prefix function or key comparison function is specified by the
+application, a default lexical comparison function is used as the prefix
+function.  If no prefix function is specified and a key comparison
+function is specified, no prefix function is used.  It is an error to
+specify a prefix function without also specifying a key comparison
+function.
+<p>The Db.set_bt_prefix interface may only be used to configure Berkeley DB before

+<p>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.  For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>As databases opened within Berkeley DB environments use the cache specified to
+the environment, it is an error to attempt to set a cache in a database
+created within an environment.
+<p>The Db.set_cachesize interface may only be used to configure Berkeley DB before

+When an error occurs in the Berkeley DB library, an exception is thrown.  In

+application debugging.
+<p>The Db.set_errcall method is used to enhance the mechanism for reporting error
+messages to the application.  The <a href="../api_java/env_set_errcall.html">DbEnv.set_errcall</a> method must be
+called with a single object argument.  The object's class must implement
+the DbErrcall interface.  In some cases, when an error occurs, Berkeley DB will
+invoke the object's errcall() method with two arguments; the first is the
+prefix string (as previously set by <a href="../api_java/db_set_errpfx.html">Db.set_errpfx</a> or

+<h3><pre>
+import com.sleepycat.db.*;
+<p>
+public void set_flags(int flags)
+	throws DbException;
+</pre></h3>
+<h1>Description</h1>
+<p>Calling Db.set_flags is additive, there is no way to clear flags.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<h3>Btree</h3>
+<p>The following flags may be specified for the Btree access method:
+<p><dl compact>
+<p><dt><a name="Db.DB_DUP">Db.DB_DUP</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+order of insertion, unless the ordering is otherwise specified by use of
+a cursor operation.  It is an error to specify both Db.DB_DUP and
+Db.DB_RECNUM.
+<p><dt><a name="Db.DB_DUPSORT">Db.DB_DUPSORT</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+duplicate comparison function.
+A default, lexical comparison will be used.
+It is an error to specify both Db.DB_DUPSORT and Db.DB_RECNUM.
+<p><dt><a name="Db.DB_RECNUM">Db.DB_RECNUM</a><dd>Support retrieval from the Btree using record numbers.  For more
+information, see the DB_GET_RECNO flag to the <a href="../api_java/db_get.html">Db.get</a> and
+<a href="../api_java/dbc_get.html">Dbc.get</a> methods.
+<p>Logical record numbers in Btree databases are mutable in the face of
+record insertion or deletion.  See the DB_RENUMBER flag in the Recno
+access method information for further discussion.
+<p>Maintaining record counts within a Btree introduces a serious point of
+contention, namely the page locations where the record counts are stored.
+In addition, the entire tree must be locked during both insertions and
+deletions, effectively single-threading the tree for those operations.
+Specifying DB_RECNUM can result in serious performance degradation for
+some applications and data sets.
+<p>It is an error to specify both DB_DUP and DB_RECNUM.
+<p><dt><a name="Db.DB_REVSPLITOFF">Db.DB_REVSPLITOFF</a><dd>Turn off reverse splitting in the Btree.  As pages are emptied in a
+database, the Berkeley DB Btree implementation attempts to coalesce empty pages
+into higher-level pages in order to keep the tree as small as possible
+and minimize tree search time.  This can hurt performance in applications
+with cyclical data demands, that is, applications where the database grows
+and shrinks repeatedly.  For example, because Berkeley DB does page-level
+locking, the maximum level of concurrency in a database of 2 pages is far
+smaller than that in a database of 100 pages, and so a database that has
+shrunk to a minimal size can cause severe deadlocking when a new cycle of
+data insertion begins.
+</dl>
+<h3>Hash</h3>
+<p>The following flags may be specified for the Hash access method:
+<p><dl compact>
+<p><dt><a name="Db.DB_DUP">Db.DB_DUP</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+order of insertion, unless the ordering is otherwise specified by use of
+a cursor operation.  It is an error to specify both Db.DB_DUP and
+Db.DB_RECNUM.
+<p><dt><a name="Db.DB_DUPSORT">Db.DB_DUPSORT</a><dd>Permit duplicate data items in the tree, i.e. insertion when the key of
+the key/data pair being inserted already exists in the tree will be
+successful.  The ordering of duplicates in the tree is determined by the
+duplicate comparison function.
+A default, lexical comparison will be used.
+It is an error to specify both Db.DB_DUPSORT and Db.DB_RECNUM.
+</dl>
+<h3>Queue</h3>
+<p>There are no additional flags that may be specified for the Queue access
+method.
+<h3>Recno</h3>
+<p>The following flags may be specified for the Recno access method:
+<p><dl compact>
+<p><dt><a name="Db.DB_RENUMBER">Db.DB_RENUMBER</a><dd>Specifying the DB_RENUMBER flag causes the logical record numbers to be
+mutable, and change as records are added to and deleted from the database.
+For example, the deletion of record number 4 causes records numbered 5
+and greater to be renumbered downward by 1.  If a cursor was positioned
+to record number 4 before the deletion, it will reference the new record
+number 4, if any such record exists, after the deletion.  If a cursor was
+positioned after record number 4 before the deletion, it will be shifted
+downward 1 logical record, continuing to reference the same record as it
+did before.
+<p>Using the <a href="../api_java/db_put.html">Db.put</a> or <a href="../api_java/dbc_put.html">Dbc.put</a> interfaces to create new
+records will cause the creation of multiple records if the record number
+is more than one greater than the largest record currently in the
+database.  For example, creating record 28, when record 25 was previously
+the last record in the database, will create records 26 and 27 as well as
+28.  Attempts to retrieve records that were created in this manner will
+result in an error return of <a href="../ref/program/errorret.html#DB_KEYEMPTY">Db.DB_KEYEMPTY</a>.
+<p>If a created record is not at the end of the database, all records
+following the new record will be automatically renumbered upward by 1.
+For example, the creation of a new record numbered 8 causes records
+numbered 8 and greater to be renumbered upward by 1.  If a cursor was
+positioned to record number 8 or greater before the insertion, it will be
+shifted upward 1 logical record, continuing to reference the same record
+as it did before.
+<p>For these reasons, concurrent access to a Recno database with the
+Db.DB_RENUMBER flag specified may be largely meaningless, although
+it is supported.
+<p><dt><a name="Db.DB_SNAPSHOT">Db.DB_SNAPSHOT</a><dd>This flag specifies that any specified <b>re_source</b> file be read in
+its entirety when <a href="../api_java/db_open.html">Db.open</a> is called.  If this flag is not
+specified, the <b>re_source</b> file may be read lazily.
+</dl>
+<p>The Db.set_flags interface may only be used to configure Berkeley DB before
+the <a href="../api_java/db_open.html">Db.open</a> interface is called.
+<p>The Db.set_flags method throws an exception that encapsulates a non-zero error value on
+failure.

+<p>Set a user defined hash method; if no hash method is specified, a default
+hash method is used.  Since no hash method performs equally well on all

+poorly with a particular data set.  User specified hash functions must
+take a pointer to a byte string and a length as arguments and return a
+value of type
+<b>int</b>.
+The hash function must handle any key values used by the application
+(possibly including zero-length keys).
+<p>If a hash method is specified, <a href="../api_java/db_open.html">Db.open</a> will attempt to determine
+if the hash method specified is the same as the one with which the database
+was created, and will fail if it detects that it is not.

+<h1>Description</h1>
+<p>Set the underlying source file for the Recno access method.  The purpose
+of the <b>re_source</b> value is to provide fast access and modification
+to databases that are normally stored as flat text files.
+<p>If the <b>re_source</b> field is set, it specifies an underlying flat
+text database file that is read to initialize a transient record number
+index.  In the case of variable length records, the records are separated
+as specified by <a href="../api_java/db_set_re_delim.html">Db.set_re_delim</a>.  For example, standard UNIX
+byte stream files can be interpreted as a sequence of variable length
+records separated by &lt;newline&gt; characters.
+<p>In addition, when cached data would normally be written back to the
+underlying database file (e.g., the <a href="../api_java/db_close.html">Db.close</a> or <a href="../api_java/db_sync.html">Db.sync</a>
+methods are called), the in-memory copy of the database will be written
+back to the <b>re_source</b> file.
+<p>By default, the backing source file is read lazily, i.e., records are not
+read from the file until they are requested by the application.
+<b>If multiple processes (not threads) are accessing a Recno database
+concurrently and either inserting or deleting records, the backing source
+file must be read in its entirety before more than a single process
+accesses the database, and only that process should specify the backing
+source file as part of the <a href="../api_java/db_open.html">Db.open</a> call.  See the <a href="../api_java/db_set_flags.html#DB_SNAPSHOT">Db.DB_SNAPSHOT</a>
+flag for more information.</b>
+<p><b>Reading and writing the backing source file specified by <b>re_source</b>
+cannot be transactionally protected because it involves filesystem
+operations that are not part of the Db transaction methodology.</b>
+For this reason, if a temporary database is used to hold the records,
+i.e., a null was specified as the <b>file</b> argument to <a href="../api_java/db_open.html">Db.open</a>,
+it is possible to lose the contents of the <b>re_source</b> file, e.g.,
+if the system crashes at the right instant.
+If a file is used to hold the database, i.e., a file name was specified
+as the <b>file</b> argument to <a href="../api_java/db_open.html">Db.open</a>, normal database
+recovery on that file can be used to prevent information loss,
+although it is still possible that the contents of <b>re_source</b>
+will be lost if the system crashes.
+<p>The <b>re_source</b> file must already exist (but may be zero-length) when
+<a href="../api_java/db_open.html">Db.open</a> is called.
+<p>It is not an error to specify a read-only <b>re_source</b> file when
+creating a database, nor is it an error to modify the resulting database.
+However, any attempt to write the changes to the backing source file using
+either the <a href="../api_java/db_sync.html">Db.sync</a> or <a href="../api_java/db_close.html">Db.close</a> methods will fail, of course.
+Specify the <a href="../api_java/db_close.html#DB_NOSYNC">Db.DB_NOSYNC</a> flag to the <a href="../api_java/db_close.html">Db.close</a> method to stop it
+from attempting to write the changes to the backing file, instead, they
+will be silently discarded.
+<p>For all of the above reasons, the <b>re_source</b> field is generally
+used to specify databases that are read-only for <a href="../api_java/db_class.html">Db</a> applications,
+and that are either generated on the fly by software tools, or modified
+using a different mechanism, e.g., a text editor.
+<p>The Db.set_re_source interface may only be used to configure Berkeley DB before
+the <a href="../api_java/db_open.html">Db.open</a> interface is called.
+<p>The Db.set_re_source method throws an exception that encapsulates a non-zero error value on
+failure.

+<h3><pre>
+import com.sleepycat.db.*;
+<p>
+public Object Db.stat(int flags);
+</pre></h3>
+<h1>Description</h1>
+<p>The Db.stat method creates a statistical structure and
+fills it with statistics for the database.
+<p>Statistical structures are created in allocated memory.  If <b>db_malloc</b> is non-NULL, it
+is called to allocate the memory, otherwise, the library function
+<b>malloc</b>(3) is used.  The function <b>db_malloc</b> must match
+the calling conventions of the <b>malloc</b>(3) library routine.
+Regardless, the caller is responsible for deallocating the returned
+memory.  To deallocate returned memory, free the returned memory
+reference, references inside the returned memory do not need to be
+individually freed.
+<p>The <b>flags</b> parameter must be set to 0 or the following value:
+<p><dl compact>
+<p><dt><a name="Db.DB_CACHED_COUNTS">Db.DB_CACHED_COUNTS</a><dd>Return a cached count of the keys and records in a database.  This flag
+makes it possible for applications to request an possibly approximate key
+and record count without incurring the performance penalty of traversing
+the entire database.  The statistics information described for the access
+method <b>XX_nkeys</b> and <b>XX_ndata</b> fields below is filled in,
+but no other information is collected.  If the cached information has
+never been set, the fields will be returned set to 0.
+<p><dt><a name="Db.DB_RECORDCOUNT">Db.DB_RECORDCOUNT</a><dd>Return a count of the records in a Btree or Recno Access Method database.
+This flag makes it possible for applications to request a record count
+without incurring the performance penalty of traversing the entire
+database.  The statistics information described for the <b>bt_nkeys</b>
+field below is filled in, but no other information is collected.
+<p>This option is only available for Recno databases, or Btree databases
+where the underlying database was created with the <a href="../api_java/db_set_flags.html#DB_RECNUM">Db.DB_RECNUM</a>
+flag.
+</dl>
+<p>The Db.stat method may access all of the pages in the database,
+incurring a severe performance penalty as well as possibly flushing the
+underlying buffer pool.
+<p>In the presence of multiple threads or processes accessing an active
+database, the information returned by Db.stat may be out-of-date.
+<p>If the database was not opened readonly and the Db.DB_CACHED_COUNTS
+flag was not specified, the cached key and record numbers will be updated
+after the statistical information has been gathered.
+<p>The Db.stat method cannot be transaction protected.  For this reason,
+it should be called in a thread of control that has no open cursors or
+active transactions.
+<p>The Db.stat method throws an exception that encapsulates a non-zero error value on
+failure.
+<h3>Hash Statistics</h3>
+<p>In the case of a Hash database,
+the statistics are returned in an instance of DbHashStat.  The data
+fields are available from DbHashStat:

+<dt>public int hash_dup_free;<dd>The number of bytes free on duplicate pages.
+</dl>
+<h3>Btree and Recno Statistics</h3>
+<p>In the case of a Btree or Recno database,

+<dt>public int bt_minkey;<dd>The minimum keys per page.
+<dt>public int bt_re_len;<dd>The length of fixed-length records.
+<dt>public int bt_re_pad;<dd>The padding byte value for fixed-length records.
+<dt>public int bt_levels;<dd>Number of levels in the database.
+<dt>public int bt_int_pg;<dd>Number of database internal pages.
+<dt>public int bt_leaf_pg;<dd>Number of database leaf pages.

+<dt>public int bt_dup_pgfree;<dd>Number of bytes free in database duplicate pages.
+<dt>public int bt_over_pgfree;<dd>Number of bytes free in database overflow pages.
+</dl>
+<h3>Queue Statistics</h3>

+<dt>public int qs_ndata;<dd>The number of records in the database.
+<dt>public int qs_pagesize;<dd>Underlying database page size.
+<dt>public int qs_pages;<dd>Number of pages in the database.
+<dt>public int qs_re_len;<dd>The length of the records.
+<dt>public int qs_re_pad;<dd>The padding byte value for the records.
+<dt>public int qs_pgfree;<dd>Number of bytes free in database pages.
+<dt>public int qs_start;<dd>Start offset.
+<dt>public int qs_first_recno;<dd>First undeleted record in the database.
+<dt>public int qs_cur_recno;<dd>Last allocated record number in the database.
+</dl>
+<p>The Db.stat method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The Db.stat method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the Db.stat method may fail and throw
+a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls

+See <a href="../ref/am/upgrade.html">Upgrading databases</a> for more
+information.</b>
+<p>Unlike all other database operations, Db.upgrade may only be done
+on a system with the same byte-order as the database.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="Db.DB_DUPSORT">Db.DB_DUPSORT</a><dd><b>This flag is only meaningful when upgrading databases from
+releases before the Berkeley DB 3.1 release.</b>
+<p>As part of the upgrade from the Berkeley DB 3.0 release to the 3.1 release, the
+on-disk format of duplicate data items changed.  To correctly upgrade the
+format requires applications specify if duplicate data items in the
+database are sorted or not.  Specifying the Db.DB_DUPSORT flag
+informs Db.upgrade that the duplicates are sorted, otherwise they
+are assumed to be unsorted.  Incorrectly specifying the value of this flag
+may lead to database corruption.
+<p>Further, because the Db.upgrade method upgrades a physical file
+(including all of the databases it contains), it is not possible to use
+Db.upgrade to upgrade files where some of the databases it
+includes have sorted duplicate data items and some of the databases it
+includes have unsorted duplicate data items.  If the file does not have
+more than a single database, or the databases do not support duplicate
+data items, or all of the databases that support duplicate data items
+support the same style of duplicates (either sorted or unsorted),
+Db.upgrade will work correctly as long as the Db.DB_DUPSORT
+flag is correctly specified.  Otherwise, the file cannot be upgraded using
+Db.upgrade, and must be upgraded manually by dumping and
+re-loading the databases.
+</dl>
+<p>The Db.upgrade method throws an exception that encapsulates a non-zero error value on
+failure.

+<p>
+public void verify(String file,
+    String database, java.io.OutputStream outfile, int flags)
+	throws DbException;
+</pre></h3>
+<h1>Description</h1>
+<p>The Db.verify method verifies the integrity of all databases in the
+file specified by the file argument, and optionally outputs the databases'
+key/data pairs to a file stream.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="Db.DB_SALVAGE">Db.DB_SALVAGE</a><dd>Write the key/data pairs from all databases in the file to the file stream
+named in
+the <b>outfile</b> argument.  The output format is the same as that
+specified for the <a href="../utility/db_dump.html">db_dump</a> utility and can be used as input for
+the <a href="../utility/db_load.html">db_load</a> utility.
+<p>Because the key/data pairs are output in page order as opposed to the sort
+order used by <a href="../utility/db_dump.html">db_dump</a>, using Db.verify to dump key/data
+pairs normally produces less than optimal loads for Btree databases.
+</dl>
+<p>In addition, the following flags may be set by bitwise inclusively <b>OR</b>'ing them into the
+<b>flags</b> parameter:
+<p><dl compact>
+<p><dt><a name="Db.DB_AGGRESSIVE">Db.DB_AGGRESSIVE</a><dd>Output <b>all</b> the key/data pairs in the file that can be found.
+By default, Db.verify does not assume corruption.  For example,
+if a key/data pair on a page is marked as deleted, it is not then written
+to the output file.  When Db.DB_AGGRESSIVE is specified, corruption
+is assumed, and any key/data pair that can be found is written.  In this
+case, key/data pairs that are corrupted or have been deleted may appear
+in the output (even if the file being salvaged is in no way corrupt), and
+the output will almost certainly require editing before being loaded into
+a database.
+<p><dt><a name="Db.DB_NOORDERCHK">Db.DB_NOORDERCHK</a><dd>Skip the database checks for btree and duplicate sort order and for
+hashing.
+<p>The Db.verify method normally verifies that btree keys and duplicate
+items are correctly sorted and hash keys are correctly hashed.  If the
+file being verified contains multiple databases using differing sorting
+or hashing algorithms, some of them must necessarily fail database
+verification as only one sort order or hash function can be specified
+before Db.verify is called.  To verify files with multiple
+databases having differing sorting orders or hashing functions, first
+perform verification of the file as a whole by using the
+Db.DB_NOORDERCHK flag, and then individually verify the sort order
+and hashing function for each database in the file using the
+Db.DB_ORDERCHKONLY flag.
+<p><dt><a name="Db.DB_ORDERCHKONLY">Db.DB_ORDERCHKONLY</a><dd>Perform the database checks for btree and duplicate sort order and for
+hashing, skipped by Db.DB_NOORDERCHK.
+<p>When this flag is specified, a <b>database</b> argument should also be
+specified, indicating the database in the physical file which is to be
+checked.  This flag is only safe to use on databases that have already
+successfully been verified using Db.verify with the
+Db.DB_NOORDERCHK flag set.
+</dl>
+<p>The database argument must be set to null except when the
+Db.DB_ORDERCHKONLY flag is set.
+<p>The Db.verify method throws an exception that encapsulates a non-zero error value on
+failure, and <a href="../ref/program/errorret.html#DB_VERIFY_BAD">Db.DB_VERIFY_BAD</a> if a database is corrupted.  When the
+Db.DB_SALVAGE flag is specified, the <a href="../ref/program/errorret.html#DB_VERIFY_BAD">Db.DB_VERIFY_BAD</a> return
+means that all key/data pairs in the file may not have been successfully
+output.

+<h1>Description</h1>
+<p>This manual page describes the specific details of the Dbt class,
+used to encode keys and data items in a database.
+        <a name="3"><!--meow--></a>    
+<h3>Key/Data Pairs</h3>
+<p>Storage and retrieval for the Db access methods are based on
+key/data pairs.  Both key and data items are represented by Dbt
+objects.  Key and data byte strings may reference strings of zero length
+up to strings of essentially unlimited length.  See
+<a href="../ref/program/dbsizes.html">Database limits</a> for more
+information.
+<p>The Dbt class provides simple access to an underlying data structure,
+whose elements can be examined or changed using the <b>set_</b> or
+<b>get_</b> methods.  The remainder of the manual page sometimes refers
+to these accesses using the underlying name, e.g., simply <b>ulen</b>
+instead of Dbt.get_ulen and Dbt.set_ulen.
+Dbt can be subclassed, providing a way to associate
+with it additional data, or references to other structures.
+<p>The constructors set all elements of the underlying structure to zero.
+The constructor with one argument has the effect of setting all elements
+to zero except for the specified <b>data</b> and <b>size</b> elements.
+The constructor with three arguments has has the additional effect of
+only using the portion of the array specified by the size and offset.
+<p>In the case where the <b>flags</b> structure element is 0, when being
+provided a key or data item by the application, the Berkeley DB package expects
+the <b>data</b> object to be set to a byte array of <b>size</b> bytes.
+When returning a key/data item to the application, the Berkeley DB package will
+store into the <b>data</b> object a byte array of <b>size</b> bytes.
+During a get operation, one of the Db.DB_DBT_MALLOC,
+Db.DB_DBT_REALLOC or Db.DB_DBT_USERMEM flags must be
+specified.
+<p>The elements of the structure underlying the Dbt class are defined as follows:
+<p><dl compact>
+<p><dt>byte[] <a name="data">data</a>;<dd>A byte array containing the data.
+This element is accessed using Dbt.get_data and
+Dbt.set_data, and may be initialized using one
+of the constructors.
+Note that the array data is not copied immediately, but only when the
+Dbt is used.
+<p><dt>int offset;<dd>The number of bytes offset into the <b>data</b> array to determine the
+portion of the array actually used.
+This element is accessed using Dbt.get_offset and
+Dbt.set_offset.
+<p><dt>int size;<dd>The length of <b>data</b>, in bytes.
+This element is accessed using Dbt.get_size and
+Dbt.set_size, and may be initialized
+implicitly to the length of the data array with the constructor having
+one argument.
+<p><dt>int ulen;<dd>The size of the user's buffer (referenced by <b>data</b>), in bytes.
+This location is not written by the Db methods.
+<p>Note that applications can determine the length of a record by setting
+the <b>ulen</b> to 0 and checking the return value found in <b>size</b>.
+See the Db.DB_DBT_USERMEM flag for more information.
+<p>This element is accessed using
+Dbt.get_ulen and Dbt.set_ulen.
+<p><dt>int dlen;<dd>The length of the partial record being read or written by the application,
+in bytes.
+See the Db.DB_DBT_PARTIAL flag for more information.
+This element is accessed using
+Dbt.get_dlen, and Dbt.set_dlen.
+<p><dt>int doff;<dd>The offset of the partial record being read or written by the application,
+in bytes.
+See the Db.DB_DBT_PARTIAL flag for more information.
+This element is accessed using
+Dbt.get_doff and Dbt.set_doff.
+<p><dt>int flags;<dd>This element is accessed using Dbt.get_flags and
+Dbt.set_flags.
+<p>The <b>flags</b> value must be set by bitwise inclusively <b>OR</b>'ing together one or more of the
+following values.
+<p><dl compact>
+<p><dt><a name="Db.DB_DBT_MALLOC">Db.DB_DBT_MALLOC</a><dd>When this flag is set Berkeley DB will allocate memory for the returned key

+byte array to contain the data.  This can be convenient if you know little
+about the nature of the data, specifically the size of data in the
+database.  However, if your application makes repeated calls to retrieve
+keys or data, you may notice increased garbage collection due to this
+allocation.  If you know the maximum size of data you are retrieving, you
+might decrease the memory burden and speed your application by allocating
+your own byte array and using Db.DB_DBT_USERMEM.  Even if you don't

+not exist in the record, the get is successful and the existing bytes
+or nul bytes are returned.
+<p>For example, if the data portion of a retrieved record was 100 bytes,
+and a partial retrieval was done using a Dbt having a <b>dlen</b>
+field of 20 and a <b>doff</b> field of 85, the get call would succeed,

+If <b>dlen</b> is smaller than <b>size</b>, the record will grow, and if
+<b>dlen</b> is larger than <b>size</b>, the record will shrink.
+If the specified bytes do not exist, the record will be extended using nul

+<p>It is an error to attempt a partial put using the <a href="../api_java/db_put.html">Db.put</a>

+field of 20, a <b>doff</b> field of 85, and a <b>size</b> field of 30,

+bytes would be those specified by the put call.
+</dl>
+</dl>
+<p>Although Java normally maintains proper alignment of byte arrays, the
+set_offset method can be used to specify unaligned addresses.  Unaligned
+address accesses that are not supported by the underlying hardware may be
+reported as an exception, or may stop the running Java program.
+        <a name="4"><!--meow--></a>    
+<h3>Logical Record Numbers</h3>
+<p>In all cases for the Queue and Recno access methods, and when calling the
+<a href="../api_java/db_get.html">Db.get</a> and <a href="../api_java/dbc_get.html">Dbc.get</a> functions with the
+<a href="../api_java/db_get.html#DB_SET_RECNO">Db.DB_SET_RECNO</a> flag specified, the <b>data</b>
+field of the key must be a four byte array, large enough to store an int.
+The Dbt.set_recno_key_data method can be used to set the value of
+the array.  An int is a 32-bit type,
+(which limits the number of logical records in a Queue or Recno database,
+and the maximum logical record which may be directly retrieved from a
+Btree database, to 4,294,967,296).  The <b>size</b> field of the key
+should be the size of that type, i.e.,
+4.
+<p>Logical record numbers are 1-based, not 0-based, i.e., the first record
+in the database is record number 1.

+<h1>Description</h1>
+<p>The DbEnv.open method is the interface for opening the Berkeley DB
+environment.  It provides a structure for creating a consistent
+environment for processes using one or more of the features of Berkeley DB.
+<p>The <b>db_home</b> argument to DbEnv.open (and file name
+resolution in general) is described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p>The <b>flags</b> argument specifies the subsystems that are initialized
+and how the application's environment affects Berkeley DB file naming, among
+other things.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p>As there are a large number of flags that can be specified, they have been
+grouped together by functionality.  The first group of flags indicate
+which of the Berkeley DB subsystems should be initialized:
+<p><dl compact>
+<p><dt><a name="Db.DB_JOINENV">Db.DB_JOINENV</a><dd>Join an existing environment.  This option allows applications to
+join an existing environment without knowing which Berkeley DB subsystems
+the environment supports.
+<p><dt><a name="Db.DB_INIT_CDB">Db.DB_INIT_CDB</a><dd>Initialize locking for the <a href="../ref/cam/intro.html">Berkeley DB Concurrent Data Store</a>
+product.  In this mode, Berkeley DB provides multiple reader/single writer
+access.  The only other subsystem that should be specified with the
+Db.DB_INIT_CDB flag is Db.DB_INIT_MPOOL.
+<p>Access method calls are largely unchanged when using this flag, although
+any cursors through which update operations (e.g., <a href="../api_java/dbc_put.html">Dbc.put</a>,
+<a href="../api_java/dbc_del.html">Dbc.del</a>) will be made must have the <a href="../api_java/db_cursor.html#DB_WRITECURSOR">Db.DB_WRITECURSOR</a> value
+set in the flags parameter to the cursor call that creates the cursor.
+See <a href="../api_java/db_cursor.html">Db.cursor</a> for more information.
+<p><dt><a name="Db.DB_INIT_LOCK">Db.DB_INIT_LOCK</a><dd>Initialize the locking subsystem.  This subsystem should be used when
+multiple processes or threads are going to be reading and writing a Berkeley DB
+database, so that they do not interfere with each other.  If all threads
+are accessing the database(s) read-only, then locking is unnecessary.
+When the DB_INIT_LOCK flag is specified, it is usually necessary to run
+the deadlock detector, as well.  See <a href="../utility/db_deadlock.html">db_deadlock</a> and
+<a href="../api_java/lock_detect.html">DbEnv.lock_detect</a> for more information.
+<p><dt><a name="Db.DB_INIT_LOG">Db.DB_INIT_LOG</a><dd>Initialize the logging subsystem.  This subsystem is used when recovery
+from application or system failure is necessary.
+<p>The log is stored in one or more files in the environment directory.
+Each file is named using the format <i>log.NNNNNNNNNN</i>, where
+<i>NNNNNNNNNN</i> is the sequence number of the file within the log.
+For further information, see
+<a href="../ref/log/limits.html">Log File Limits</a>.
+<p>If the log region is being created and log files are already present, the
+log files are reviewed and subsequent log writes are appended
+to the end of the log, rather than overwriting current log entries.
+<p><dt><a name="Db.DB_INIT_MPOOL">Db.DB_INIT_MPOOL</a><dd>Initialize the shared memory buffer pool subsystem.  This subsystem is
+used whenever the application is using any Berkeley DB access method.
+<p><dt><a name="Db.DB_INIT_TXN">Db.DB_INIT_TXN</a><dd>Initialize the transaction subsystem.  This subsystem is used when
+recovery and atomicity of multiple operations and recovery are important.
+The DB_INIT_TXN flag implies the DB_INIT_LOG flag.
+</dl>
+<p>The second group of flags govern what recovery, if any, is performed when
+the environment is initialized:
+<p><dl compact>
+<p><dt><a name="Db.DB_RECOVER">Db.DB_RECOVER</a><dd>Run normal recovery on this environment before opening it for normal use.
+If this flag is set, the DB_CREATE flag must also be set since the regions
+will be removed and recreated.
+<p><dt><a name="Db.DB_RECOVER_FATAL">Db.DB_RECOVER_FATAL</a><dd>Run catastrophic recovery on this environment before opening it for normal
+use.  If this flag is set, the DB_CREATE flag must also be set since the
+regions will be removed and recreated.
+</dl>
+<p>A standard part of the recovery process is to remove the existing Berkeley DB
+environment and create a new one in which to perform recovery.  If the
+thread of control performing recovery does not specify the correct region
+initialization information (e.g., the correct memory pool cache size),
+the result can be an application running in an environment with incorrect
+cache and other subsystem sizes.  For this reason, the thread of control
+performing recovery should either specify correct configuration
+information before calling the DbEnv.open method, or it should remove
+the environment after recovery is completed, leaving creation of the
+correctly sized environment to a subsequent call to DbEnv.open.
+<p>All Berkeley DB recovery processing must be single-threaded, that is, only a
+single thread of control may perform recovery or access a Berkeley DB
+environment while recovery is being performed.  As it is not an error to
+specify Db.DB_RECOVER for an environment for which no recovery is
+required, it is reasonable programming practice for the thread of control
+responsible for performing recovery and creating the environment to always
+specify the Db.DB_RECOVER flag during startup.
+<p>The DbEnv.open function returns successfully if Db.DB_RECOVER
+or Db.DB_RECOVER_FATAL is specified and no log files exist, so it is
+necessary to ensure all necessary log files are present before running
+recovery.  For further information, consult <a href="../utility/db_archive.html">db_archive</a> and
+<a href="../utility/db_recover.html">db_recover</a>.
+<p>The third group of flags govern file naming extensions in the environment:
+<p><dl compact>
+<!--$Id: m4.env_flags,v 10.9 2000/06/29 22:54:10 bostic Exp $-->
+<p><dt><a name="Db.DB_USE_ENVIRON">Db.DB_USE_ENVIRON</a><dd>The Berkeley DB process' environment may be permitted to specify information to
+be used when naming files; see <a href="../ref/env/naming.html">Berkeley DB
+File Naming</a>.  As permitting users to specify which files are used can
+create security problems, environment information will be used in file
+naming for all users only if the DB_USE_ENVIRON flag is set.
+<p><dt><a name="Db.DB_USE_ENVIRON_ROOT">Db.DB_USE_ENVIRON_ROOT</a><dd>The Berkeley DB process' environment may be permitted to specify information to
+be used when naming files; see <a href="../ref/env/naming.html">Berkeley DB
+File Naming</a>.  As permitting users to specify which files are used can
+create security problems, if the DB_USE_ENVIRON_ROOT flag is set,
+environment information will be used for file naming only for users with
+appropriate permissions (e.g., on UNIX systems, users with a user-ID of 0).
+</dl>
+<p>Finally, there are a few additional, unrelated flags:
+<p><dl compact>
+<p><dt><a name="Db.DB_CREATE">Db.DB_CREATE</a><dd>Cause Berkeley DB subsystems to create any underlying files, as necessary.
+<p><dt><a name="Db.DB_LOCKDOWN">Db.DB_LOCKDOWN</a><dd>Lock shared Berkeley DB environment files and memory mapped databases into memory.
+<p><dt><a name="Db.DB_PRIVATE">Db.DB_PRIVATE</a><dd>Specify that the environment will only be accessed by a single process
+(although that process may be multi-threaded).  This flag has two effects
+on the Berkeley DB environment.  First, all underlying data structures are
+allocated from per-process memory instead of from shared memory that is
+potentially accessible to more than a single process.  Second, mutexes
+are only configured to work between threads.
+<p>This flag should not be specified if more than a single process is
+accessing the environment, as it is likely to cause database corruption
+and unpredictable behavior, e.g., if both a server application and the
+Berkeley DB utility <a href="../utility/db_stat.html">db_stat</a> will access the environment, the
+Db.DB_PRIVATE flag should not be specified.
+<p><dt><a name="Db.DB_SYSTEM_MEM">Db.DB_SYSTEM_MEM</a><dd>Allocate memory from system shared memory instead of from memory backed
+by the filesystem.  See <a href="../ref/env/region.html">Shared Memory
+Regions</a> for more information.
+<p><dt><a name="Db.DB_THREAD">Db.DB_THREAD</a><dd>Cause the <a href="../api_java/dbenv_class.html">DbEnv</a> handle returned by DbEnv.open to be
+<i>free-threaded</i>, that is, useable by multiple threads within a
+single address space.
+<p>Threading is always assumed in the Java API, so no special flags are
+required and Berkeley DB functions will always behave as if the Db.DB_THREAD
+flag was specified.
+</dl>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by Berkeley DB
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p>The DbEnv.open method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Environment Variables</h1>
+<p><dl compact>
+<p><dt>DB_HOME<dd>The environment variable <b>DB_HOME</b> may be used as the path of
+the database home as described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+</dl>
+<h1>Errors</h1>
+<p>The DbEnv.open method may fail and throw an exception encapsulating a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EAGAIN<dd>The shared memory region was locked and (repeatedly) unavailable.
+</dl>
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>
+The Db.DB_THREAD flag was specified and spinlocks are not
+implemented for this architecture.
+<p>The DB_HOME or TMPDIR environment variables were set but empty.
+<p>An incorrectly formatted <b>NAME VALUE</b> entry or line was found.
+</dl>
+<p><dl compact>
+<p><dt>ENOSPC<dd>HP-UX only: a previously created Berkeley DB environment for this process still
+exists.
+</dl>
+<p>If the file or directory does not exist, the DbEnv.open method will
+fail and
+throw a FileNotFoundException exception.
+<p>The DbEnv.open method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv.open method may fail and throw
+a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls

+<h1>Description</h1>
+<p>The DbEnv.remove method destroys a Berkeley DB environment, if it is not
+currently in use.  The environment regions, including any backing files,
+are removed.  Any log or database files and the environment directory are
+not removed.
+<p>The <b>db_home</b> argument to DbEnv.remove is described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p>If there are processes that have called <a href="../api_java/env_open.html">DbEnv.open</a> without
+calling <a href="../api_java/env_close.html">DbEnv.close</a> (i.e., there are processes currently using
+the environment), DbEnv.remove will fail without further action,
+unless the <a href="../api_java/env_remove.html#DB_FORCE">Db.DB_FORCE</a> flag is set, in which case
+DbEnv.remove will attempt to remove the environment regardless
+of any processes still using it.
+<p>The result of attempting to forcibly destroy the environment when it is
+in use is unspecified.  Processes using an environment often maintain open
+file descriptors for shared regions within it.  On UNIX systems, the
+environment removal will usually succeed and processes that have already
+joined the region will continue to run in that region without change,
+however processes attempting to join the environment will either fail or
+create new regions.  On other systems (e.g., Windows/NT), where the
+<b>unlink</b>(2) system call will fail if any process has an open
+file descriptor for the file, the region removal will fail.
+<p>Calling DbEnv.remove should not be necessary for most applications,
+as the Berkeley DB environment is cleaned up as part of normal database recovery
+procedures, however, applications may wish to call DbEnv.remove
+as part of application shutdown to free up system resources.
+Specifically, when the <a href="../api_java/env_open.html#DB_SYSTEM_MEM">Db.DB_SYSTEM_MEM</a> flag was specified to
+<a href="../api_java/env_open.html">DbEnv.open</a>, it may be useful to call DbEnv.remove in order
+to release system shared memory segments that have been allocated.
+<p>In the case of catastrophic or system failure, database recovery must be
+performed (see <a href="../utility/db_recover.html">db_recover</a>), or the <a href="../api_java/env_open.html#DB_RECOVER">Db.DB_RECOVER</a> and
+<a href="../api_java/env_open.html#DB_RECOVER_FATAL">Db.DB_RECOVER_FATAL</a> flags to <a href="../api_java/env_open.html">DbEnv.open</a> must be specified
+when the environment is re-opened.  Alternatively, if recovery is not
+required because no database state is maintained across failures, and
+the <a href="../api_java/env_open.html#DB_SYSTEM_MEM">Db.DB_SYSTEM_MEM</a> flag was not specified when the environment
+was created, it is possible to clean up an environment by removing all
+of the files in the environment directory that begin with the string
+prefix "__db", as no backing files are created in any other directory.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="Db.DB_FORCE">Db.DB_FORCE</a><dd>If the <a href="../api_java/env_remove.html#DB_FORCE">Db.DB_FORCE</a> flag is set, the environment is removed regardless

+during this process.  (Generally, the <a href="../api_java/env_remove.html#DB_FORCE">Db.DB_FORCE</a> flag is only
+specified when applications were unable to shut down cleanly, and there
+is a risk that an application may have died holding a Berkeley DB lock.)

+<h1>Description</h1>
+<p>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.  For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>The DbEnv.set_cachesize interface may only be used to configure Berkeley DB before
+the <a href="../api_java/env_open.html">DbEnv.open</a> interface is called.
+<p>The DbEnv.set_cachesize method throws an exception that encapsulates a non-zero error value on
+failure.
+<p>The database environment's cache size may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_cachesize", one or more whitespace characters,
+and the three arguments specified to this interface, separated by whitespace
+characters, for example, "set_cachesize 1 500 2".  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+<h1>Description</h1>
+When an error occurs in the Berkeley DB library, an exception is thrown.  In
+some cases, however, the <b>errno</b> value may be insufficient to
+completely describe the cause of the error, especially during initial
+application debugging.
+<p>The DbEnv.set_errcall method is used to enhance the mechanism for reporting error
+messages to the application.  The DbEnv.set_errcall method must be
+called with a single object argument.  The object's class must implement
+the DbErrcall interface.  In some cases, when an error occurs, Berkeley DB will
+invoke the object's errcall() method with two arguments; the first is the
+prefix string (as previously set by <a href="../api_java/db_set_errpfx.html">Db.set_errpfx</a> or
+<a href="../api_java/env_set_errpfx.html">DbEnv.set_errpfx</a>), the second will be an error message string.
+It is up to this method to display the message in an appropriate manner.
+<p>Alternatively, you can use the <a href="../api_java/env_set_error_stream.html">DbEnv.set_error_stream</a> method to display
+the additional information via an output stream.  You should not mix these
+approaches.
+<p>This error logging enhancement does not slow performance or significantly
+increase application size, and may be run during normal operation as well
+as during application debugging.
+<p>The DbEnv.set_errcall interface may be used to configure Berkeley DB at any time
+during the life of the application.

+<h1>Description</h1>
+<p>Some operations performed by the Berkeley DB library can take non-trivial
+amounts of time.  The DbEnv.set_feedback method can be used by
+applications to monitor progress within these operations.
+<p>When an operation is likely to take a long time, Berkeley DB will call the
+specified callback method.  This method must be declared with
+three arguments: the first will be a reference to the enclosing
+environment, the second a flag value, and the third the percent of the
+operation that has been completed, specified as an integer value between
+0 and 100.  It is up to the callback method to display this
+information in an appropriate manner.
+<p>The <b>opcode</b> argument may take on any of the following values:
+<p><dl compact>
+<p><dt><a name="Db.DB_RECOVER">Db.DB_RECOVER</a><dd>The environment is being recovered.
+</dl>
+<p>The DbEnv.set_feedback interface may be used to configure Berkeley DB at any time
+during the life of the application.
+<p>The DbEnv.set_feedback method throws an exception that encapsulates a non-zero error value on
+failure.

+will be maintained but it is possible that some number of the most
+recently committed transactions may be undone during recovery instead of
+being redone.
+<p>The number of transactions that are potentially at risk is governed by

+information) and how many log updates can fit on a single log page.

+and specify which transaction should be aborted in the case of a deadlock.
+The specified value must be one of the following list:
+<p><dl compact>
+<p><dt><a name="DB_LOCK_DEFAULT">DB_LOCK_DEFAULT</a><dd>Use the default policy as specified by <a href="../utility/db_deadlock.html">db_deadlock</a>.
+<dt><a name="DB_LOCK_OLDEST">DB_LOCK_OLDEST</a><dd>Abort the oldest transaction.
+<dt><a name="DB_LOCK_RANDOM">DB_LOCK_RANDOM</a><dd>Abort a random transaction involved in the deadlock.
+<dt><a name="DB_LOCK_YOUNGEST">DB_LOCK_YOUNGEST</a><dd>Abort the youngest transaction.
+</dl>
+<p>The DbEnv.set_lk_detect interface may only be used to configure Berkeley DB before
+the <a href="../api_java/env_open.html">DbEnv.open</a> interface is called.
+<p>The DbEnv.set_lk_detect method throws an exception that encapsulates a non-zero error value on
+failure.
+<p>The database environment's deadlock detector configuration may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_lk_detect", one or more whitespace characters,
+and the interface <b>detect</b> argument as a string, for example,
+"set_lk_detect DB_LOCK_OLDEST".  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+<p>Page-fault shared regions into memory when initially creating or joining
+a Berkeley DB environment.  In some applications, the expense of page-faulting
+the shared memory regions can affect performance, e.g., when the
+page-fault occurs while holding a lock, other lock requests can convoy
+and overall throughput may decrease.  Setting <b>region_init</b> to a
+true value specifies that shared regions be read or written, as
+appropriate, when the region is joined by the application.  This forces
+the underlying virtual memory and file systems to instantiate both the
+necessary memory and the necessary disk space.  This can also avoid
+out-of-disk space failures later on.
+<p>The DbEnv.set_region_init interface affects the entire application, not a single

+<p>The DbEnv.set_region_init method throws an exception that encapsulates a non-zero error value on
+failure.
+<p>The database environment's initial behavior with respect to shared memory regions may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_region_init", one or more whitespace characters,
+and the string "1".  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+<h1>Description</h1>
+<p>Specify a base segment ID for Berkeley DB environment shared memory regions
+created in system memory on VxWorks or systems supporting X/Open-style
+shared memory interfaces, e.g., UNIX systems supporting
+<b>shmget</b>(2) and related System V IPC interfaces.
+<p>This base segment ID will be used when Berkeley DB shared memory regions are
+first created.  It will be incremented a small integer value each time
+a new shared memory region is created, that is, if the base ID is 35,
+the first shared memory region created will have a segment ID of 35 and
+the next one a segment ID between 36 and 40 or so.  A Berkeley DB environment
+always creates a master shared memory region, plus an additional shared
+memory region for each of the subsystems supported by the environment
+(locking, logging, memory pool and transaction), plus an additional
+shared memory region for each additional memory pool cache that is
+supported.  Already existing regions with the same segment IDs will be
+removed.  See <a href="../ref/env/region.html">Shared Memory Regions</a>
+for more information.
+<p>The intent behind this interface is two-fold: without it, applications
+have no way to ensure that two Berkeley DB applications don't attempt to use
+the same segment IDs when creating different Berkeley DB environments.  In
+addition, by using the same segment IDs each time the environment is
+created, previously created segments will be removed, and the set of
+segments on the system will not grow without bound.
+<p>The DbEnv.set_shm_key interface may only be used to configure Berkeley DB before
+the <a href="../api_java/env_open.html">DbEnv.open</a> interface is called.
+<p>The DbEnv.set_shm_key method throws an exception that encapsulates a non-zero error value on
+failure.
+<p>The database environment's base segment ID may also be set using the environment's
+<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
+single line with the string "set_shm_key", one or more whitespace characters,
+and the ID.  Because the <b>DB_CONFIG</b> file is read when the database
+environment is opened, it will silently overrule configuration done
+before that time.

+and the interface <b>which</b> argument as a string, for example,
+"set_verbose DB_VERB_CHKPOINT".  Because the <b>DB_CONFIG</b> file is read when the database

+existing lock, return immediately instead of waiting for the lock to
+become available.
+</dl>
+<p>The <b>obj</b> argument is an untyped byte string that specifies the
+object to be locked or released.
+<p>The <b>mode</b> argument is an index into the environment's lock conflict
+array.  See <a href="../api_java/env_set_lk_conflicts.html">DbEnv.set_lk_conflicts</a> and
+<a href="../ref/lock/stdmode.html">Standard Lock Modes</a>

+</pre></h3>
+<h1>Description</h1>
+<p>The DbEnv.log_archive method
+returns an array of log or database file names.
+<p>By default, DbEnv.log_archive returns the names of all of the log files
+that are no longer in use (e.g., no longer involved in active transactions),
+and that may safely be archived for catastrophic recovery and then removed
+from the system.  If there were no file names to return, the memory location
+referenced by <b>listp</b> will be set to null.
+<p>The <b>flags</b> value must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one or more
+of the following values.
+<p><dl compact>
+<p><dt><a name="Db.DB_ARCH_ABS">Db.DB_ARCH_ABS</a><dd>All pathnames are returned as absolute pathnames,
+instead of relative to the database home directory.
+<p><dt><a name="Db.DB_ARCH_DATA">Db.DB_ARCH_DATA</a><dd>Return the database files that need to be archived in order to recover
+the database from catastrophic failure.  If any of the database files
+have not been accessed during the lifetime of the current log files,
+DbEnv.log_archive will not include them in this list.  It is also
+possible that some of the files referenced in the log have since been
+deleted from the system.
+<p><dt><a name="Db.DB_ARCH_LOG">Db.DB_ARCH_LOG</a><dd>Return all the log file names regardless of whether or not they are in
+use.
+</dl>
+<p>The Db.DB_ARCH_DATA and Db.DB_ARCH_LOG flags are mutually
+exclusive.
+<p>See the <a href="../utility/db_archive.html">db_archive</a> manual page for more information on database
+archival procedures.
+<p>The DbEnv.log_archive method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Bugs</h1>
+<p>In a threaded application (i.e., one where the environment was created
+with the DB_THREAD flag specified), calling DbEnv.log_archive with the
+DB_ARCH_DATA flag will fail, returning EINVAL.  To work around this
+problem, re-open the log explicitly without specifying DB_THREAD.  This
+restriction is expected to be removed in a future version of Berkeley DB.
+<h1>Errors</h1>
+<p>The DbEnv.log_archive method may fail and throw an exception encapsulating a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+<p>The log was corrupted.
+</dl>
+<p>The DbEnv.log_archive method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv.log_archive method may fail and throw
+a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls
+will fail in the same way.

+<p>The DbEnv.memp_stat method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The DbEnv.memp_stat method may fail and throw an exception encapsulating a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+</dl>
+<p>The DbEnv.memp_stat method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv.memp_stat method may fail and throw

+<h1>Description</h1>
+<p>The DbEnv.memp_trickle method ensures that at least <b>pct</b> percent of
+the pages in the shared memory pool are clean by writing dirty pages to
+their backing files.
+The number of pages that were written to reach the correct percentage is
+returned.
+<p>The purpose of the DbEnv.memp_trickle function is to enable a memory
+pool manager to ensure that a page is always available for reading in new
+information without having to wait for a write.
+<p>The DbEnv.memp_trickle method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The DbEnv.memp_trickle method may fail and throw an exception encapsulating a non-zero error for the following conditions:
+<p><dl compact>
+<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
+</dl>
+<p>The DbEnv.memp_trickle method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbEnv.memp_trickle method may fail and throw
+a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls
+will fail in the same way.

+<h1>Description</h1> 
+<p>This manual page describes the DbRunRecoveryException class and
+how it is used by the various Db* classes.
+<p>Errors can occur in the Berkeley DB library where the only solution is to shut
+down the application and run recovery.  (For example, if Berkeley DB is unable
+to write log records to disk because there is insufficient disk space.)
+When a fatal error occurs in Berkeley DB, methods will throw a
+DbRunRecoveryException, at which point all subsequent database
+calls will also fail in the same way.  When this occurs, recovery should
+be performed.

+<h1>Description</h1>
+<p>The DbTxn.abort method causes an abnormal termination of the
+transaction.  The log is played backwards and any necessary recovery
+operations are initiated through the <b>recover</b> function specified
+to <a href="../api_java/env_open.html">DbEnv.open</a>.  After the log processing is completed, all locks
+held by the transaction are released.  As is the case for
+<a href="../api_java/txn_commit.html">DbTxn.commit</a>, applications that require strict two-phase locking
+should not explicitly release any locks.
+<p>In the case of nested transactions, aborting a parent transaction causes
+all children (unresolved or not) of the parent transaction to be aborted.
+<p>Once the DbTxn.abort method returns, the <a href="../api_java/txn_class.html">DbTxn</a> handle may not
+be accessed again.
+<p>The DbTxn.abort method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The DbTxn.abort method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbTxn.abort method may fail and throw
+a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls
+will fail in the same way.

+<h1>Description</h1>
+<p>This manual page describes the specific details of the DbTxn class.
+<p>The <a href="../api_java/dbenv_class.html">DbEnv</a> transaction methods and the DbTxn class provide
+transaction semantics.  Full transaction support is provided by a
+collection of modules that provide interfaces to the services required
+for transaction processing.  These services are recovery, concurrency
+control and the management of shared data.
+<p>Transaction semantics can be applied to the access methods described in
+Db through method call parameters.
+<p>The model intended for transactional use (and the one that is used by
+the access methods) is write-ahead logging to record both before- and
+after-images.  Locking follows a two-phase protocol, with all locks being
+released at transaction commit.

+</pre></h3>
+<h1>Description</h1>
+<p>The DbTxn.commit method ends the transaction.  In the case of nested
+transactions, if the transaction is a parent transaction, committing
+the parent transaction causes all unresolved children of the parent to
+be committed.
+<p>In the case of nested transactions, if the transaction is a child
+transaction, its locks are not released, but are acquired by its parent.
+While the commit of the child transaction will succeed, the actual
+resolution of the child transaction is postponed until the parent
+transaction is committed or aborted, i.e., if its parent transaction
+commits, it will be committed, and if its parent transaction aborts, it
+will be aborted.
+<p>The <b>flags</b> parameter must be set to 0 or one of the following
+values:
+<p><dl compact>
+<p><dt><a name="Db.DB_TXN_NOSYNC">Db.DB_TXN_NOSYNC</a><dd>Do not synchronously flush the log.  This means the transaction will
+exhibit the ACI (atomicity, consistency and isolation) properties, but
+not D (durability), i.e., database integrity will be maintained but it is
+possible that this transaction may be undone during recovery instead of
+being redone.
+<p>This behavior may be set for an entire Berkeley DB environment as part of the
+<a href="../api_java/env_set_flags.html">DbEnv.set_flags</a> interface.
+<p><dt><a name="Db.DB_TXN_SYNC">Db.DB_TXN_SYNC</a><dd>Synchronously flush the log.  This means the transaction will exhibit
+all of the ACID (atomicity, consistency and isolation and durability)
+properties.
+<p>This behavior is the default for Berkeley DB environments unless the
+<a href="../api_java/env_open.html#DB_TXN_NOSYNC">Db.DB_TXN_NOSYNC</a> flag was specified to the <a href="../api_java/env_set_flags.html">DbEnv.set_flags</a>
+or <a href="../api_java/txn_begin.html">DbEnv.txn_begin</a> interfaces.
+</dl>
+<p>Once the DbTxn.commit method returns, the <a href="../api_java/txn_class.html">DbTxn</a> handle may not
+be accessed again.  If DbTxn.commit encounters an error, the
+transaction and all child transactions of the transaction are aborted.
+<p>The DbTxn.commit method throws an exception that encapsulates a non-zero error value on
+failure.
+<h1>Errors</h1>
+<p>The DbTxn.commit method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
+If a catastrophic error has occurred, the DbTxn.commit method may fail and throw
+a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls
+will fail in the same way.

+<h1>Description</h1>
+<p>The <i>db</i> <b>close</b> command flushes any cached database information to
+disk, closes any open cursors, frees any allocated resources, and closes
+any underlying files.  Since key/data pairs are cached in memory, failing
+to sync the file with the <i>db</i> <b>close</b> or <i>db</i> <b>sync</b> command may
+result in inconsistent or lost information.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt>-nosync<dd>Do not flush cached information to disk.
+<p>The -nosync flag is a dangerous option. It should only be set if the
+application is doing logging (with transactions) so that the database is
+recoverable after a system or application crash, or if the database is
+always generated from scratch after any system or application crash.
+<p>It is important to understand that flushing cached information to disk
+only minimizes the window of opportunity for corrupted data. While
+unlikely, it is possible for database corruption to happen if a system or
+application crash occurs while writing data to the database. To ensure
+that database corruption never occurs, applications must either: use
+transactions and logging with automatic recovery, use logging and
+application-specific recovery, or edit a copy of the database, and, once
+all applications using the database have successfully called
+<i>db</i> <b>close</b>, atomically replace the original database with the updated
+copy.
+</dl>
+<p>Once <i>db</i> <b>close</b> has been called, regardless of its return, the DB
+handle may not be accessed again.
+<p>The <i>db</i> <b>close</b> command returns 0 on success, and in the case of error, a Tcl error
+is thrown.

+<h1>Description</h1>
+<p>The <i>db</i> <b>get</b> command returns key/data pairs from the database.
+<p>In the presence of duplicate key values, <i>db</i> <b>get</b> will return all
+duplicate items.  Duplicates are sorted by insert order except where this
+order has been overridden by cursor operations.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt>-consume<dd>Return the record number and data from the available record closest to
+the head of the queue and delete the record. The cursor will be
+positioned on the deleted record.  A record is available if it is not
+deleted and is not currently locked.  The underlying database must be
+of type Queue for <b>-consume</b> to be specified.
+<p><dt>-consume_wait<dd>The same as the <b>-consume</b> flag except that if the Queue database
+is empty, the thread of control will wait until there is data in the
+queue before returning.  The underlying database must be of type Queue
+for <b>-consume_wait</b> to be specified.
+<p><dt>-get_both key data<dd>Retrieve the key/data pair only if both the key and data match the
+arguments.
+<p><dt>-glob<dd>Return all keys matching the given key, where the key is a simple wildcard
+pattern.  Where it is used, it replaces the use of the key with the given
+pattern of a set of keys.  Any characters after the wildcard character
+are ignored.  For example, in a database of last names, the
+command "db0 get Jones" will return all of the "Jones" in the database,
+and the command "db0 get -glob Jo*" will return both "Jones" and "Johnson"
+from the database.  The command "db0 get -glob *" will return all of the
+key/data pairs in the database.
+<p><dt>-partial {doff dlen}<dd>The <b>dlen</b> bytes starting <b>doff</b> bytes from the beginning of
+the retrieved data record are returned as if they comprised the entire
+record. If any or all of the specified bytes do not exist in the record,
+the command is successful and the existing bytes or 0 bytes are
+returned.
+<p><dt>-recno<dd>Retrieve the specified numbered key/data pair from a database.  For
+<b>-recno</b> to be specified, the specified key must be a record number
+and the underlying database must be of type Recno or Queue, or of type
+Btree that was created with the <b>-recnum</b> option.
+<p><dt>-rmw<dd>Acquire write locks instead of read locks when doing the retrieval.
+Setting this flag may decrease the likelihood of deadlock during a
+read-modify-write cycle by immediately acquiring the write lock during
+the read part of the cycle so that another thread of control acquiring a
+read lock for the same item, in its own read-modify-write cycle, will not
+result in deadlock.
+<p>As the <i>db</i> <b>get</b> command will not hold locks across Berkeley DB interface
+calls in non-transactional environments, the <b>-rmw</b> argument to the
+<i>db</i> <b>get</b> call is only meaningful in the presence of transactions.
+<p><dt>-txn txnid<dd>If the file is being accessed under transaction protection, the
+<b>txnid</b> parameter is a transaction handle returned from <i>env</i> <b>txn</b>.
+</dl>
+<p>If the underlying database is a Queue or Recno database, then the given
+key will be interpreted by Tcl as an integer.  For all other database
+types, the key is interpreted by Tcl as a byte array unless indicated
+by a given option.
+<p>A list of key/data pairs is returned.  In the error case that no matching
+key exists, an empty list is returned.  In all other cases, a Tcl error
+is thrown.

+<h1>Description</h1>
+<p>The <b>berkdb open</b> command opens, and optionally creates, a database.
+The returned database handle is bound to a Tcl command of the form
+<b>dbN</b>, where N is an integer starting at 0 (e.g., db0 and db1).
+It is through this Tcl command that the script accesses the database
+methods.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt>-btree<dd>Open/create a database of type Btree.  The Btree format
+is a representation of a sorted, balanced tree structure.
+<p><dt>-hash<dd>Open/create a database of type Hash.  The Hash format is
+an extensible, dynamic hashing scheme.
+<p><dt>-queue<dd>Open/create a database of type Queue.  The Queue format
+supports fast access to fixed-length records accessed by sequentially or
+logical record number.
+<p><dt>-recno<dd>Open/create a database of type Recno.  The Recno format
+supports fixed- or variable-length records, accessed sequentially or by
+logical record number, and optionally retrieved from a flat text file.
+<p><dt>-unknown<dd>The database is of an unknown type, and must already exist.
+<p><dt>-cachesize {gbytes bytes ncache}<dd>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p>As databases opened within Berkeley DB environments use the cache specified to
+the environment, it is an error to attempt to set a cache in a database
+created within an environment.
+<p><dt>-create<dd>Create any underlying files, as necessary. If the files do not already
+exist and the <b>-create</b> argument is not specified, the call will
+fail.
+<p><dt>-delim delim<dd>Set the delimiting byte used to mark the end of a record in the backing
+source file for the Recno access method.
+<p>This byte is used for variable length records, if the <b>-source</b>
+argument file is specified.  If the <b>-source</b> argument file is
+specified and no delimiting byte was specified, &lt;newline&gt;
+characters (i.e. ASCII 0x0a) are interpreted as end-of-record markers.
+<p><dt>-dup<dd>Permit duplicate data items in the tree, i.e. insertion when the key of the
+key/data pair being inserted already exists in the tree will be successful.
+The ordering of duplicates in the tree is determined by the order of
+insertion, unless the ordering is otherwise specified by use of a cursor or
+a duplicate comparison function.
+<p>It is an error to specify both <b>-dup</b> and <b>-recnum</b>.
+<p><dt>-dupsort<dd>Sort duplicates within a set of data items.  A default, lexical comparison
+will be used.  Specifying that duplicates are to be sorted changes the
+behavior of the <i>db</i> <b>put</b> operation as well as the <i>dbc</i> <b>put</b>
+operation when the <b>-keyfirst</b>, <b>-keylast</b> and
+<b>-current</b> options are specified.
+<p><dt>-env env<dd>If no <b>-env</b> argument is given, the database is standalone, i.e.,
+it is not part of any Berkeley DB environment.
+<p>If a <b>-env</b> argument is given, the database is created within the
+specified Berkeley DB environment. The database access methods automatically
+make calls to the other subsystems in Berkeley DB based on the enclosing
+environment. For example, if the environment has been configured to use
+locking, then the access methods will automatically acquire the correct
+locks when reading and writing pages of the database.
+<p><dt>-errfile filename<dd>
+<p>When an error occurs in the Berkeley DB library, a Berkeley DB error or an error
+return value is returned by the function. In some cases, however, the
+errno value may be insufficient to completely describe the cause of the
+error especially during initial application debugging.
+<p>The <b>-errfile</b> argument is used to enhance the mechanism for
+reporting error messages to the application by specifying a file to be
+used for displaying additional Berkeley DB error messages. In some cases, when
+an error occurs, Berkeley DB will output an additional error message to the
+specified file reference.
+<p>The error message will consist of a Tcl command name and a colon (":"),
+an error string, and a trailing &lt;newline&gt; character.  If the
+database was opened in an environment the Tcl command name will be the
+environment name (e.g., env0), otherwise it will be the database command
+name (e.g., db0).
+<p>This error logging enhancement does not slow performance or significantly
+increase application size, and may be run during normal operation as well
+as during application debugging.
+<p>For database handles opened inside of Berkeley DB environments, specifying the
+<b>-errfile</b> argument affects the entire environment and is equivalent
+to specifying the same argument to the <b>berkdb env</b> command.
+<p><dt>-excl<dd>Return an error if the file already exists. Underlying filesystem
+primitives are used to implement this flag.  For this reason it is only
+applicable to the physical database file and cannot be used to test if a
+database in a file already exists.
+<p><dt>-extent size<dd>Set the size of the extents of the Queue database,  The size is specified
+as the number of pages in an extent.
+Each extent is created as a separate physical file. If no extent size
+is set, the default behavior is to create only
+a single underlying database file.
+<p>For information on tuning the extent size, see
+<a href="../ref/am_conf/extentsize.html">Selecting a extent size</a>.
+<p><dt>-ffactor density<dd>Set the desired density within the hash table.
+<p>The density is an approximation of the number of keys allowed to
+accumulate in any one bucket
+<p><dt>-len len<dd>For the Queue access method, specify that the records are of length
+<b>len</b>.
+<p>For the Recno access method, specify that the records are fixed-length,
+not byte delimited, and are of length <b>len</b>.
+<p>Any records added to the database that are less than <b>len</b> bytes
+long are automatically padded (see the <b>-pad</b> argument for more
+information).
+<p>Any attempt to insert records into the database that are greater than
+<b>len</b> bytes long will cause the call to fail immediately and return
+an error.
+<p><dt>-mode mode<dd>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by the access methods
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p><dt>-nelem size<dd>Set an estimate of the final size of the hash table.
+<p>If not set or set too low, hash tables will still expand gracefully as
+keys are entered, although a slight performance degradation may be
+noticed.
+<p><dt>-pad pad<dd>Set the padding character for short, fixed-length records for the Queue
+and Recno access methods.
+<p>If no pad character is specified, &lt;space&gt; characters (i.e.,
+ASCII 0x20) are used for padding.
+<p><dt>-pagesize pagesize<dd>Set the size of the pages used to hold items in the database, in bytes.
+The minimum page size is 512 bytes and the maximum page size is 64K bytes.
+If the page size is not explicitly set, one is selected based on the
+underlying filesystem I/O block size.  The automatically selected size
+has a lower limit of 512 bytes and an upper limit of 16K bytes.
+<p>For information on tuning the Berkeley DB page size, see
+<a href="../ref/am_conf/pagesize.html">Selecting a page size</a>.
+<p><dt>-rdonly<dd>Open the database for reading only. Any attempt to modify items in the
+database will fail regardless of the actual permissions of any underlying
+files.
+<p><dt>-recnum<dd>Support retrieval from the Btree using record numbers.
+<p>Logical record numbers in Btree databases are mutable in the face of
+record insertion or deletion. See the <b>-renumber</b> argument for
+further discussion.
+<p>Maintaining record counts within a Btree introduces a serious point of
+contention, namely the page locations where the record counts are stored. In
+addition, the entire tree must be locked during both insertions and
+deletions, effectively single-threading the tree for those operations.
+Specifying <b>-recnum</b> can result in serious performance degradation
+for some applications and data sets.
+<p>It is an error to specify both <b>-dup</b> and <b>-recnum</b>.
+<p><dt>-renumber<dd>Specifying the <b>-renumber</b> argument causes the logical record
+numbers to be mutable, and change as records are added to and deleted from
+the database.  For example, the deletion of record number 4 causes records
+numbered 5 and greater to be renumbered downward by 1. If a cursor was
+positioned to record number 4 before the deletion, it will reference the
+new record number 4, if any such record exists, after the deletion. If a
+cursor was positioned after record number 4 before the deletion, it will
+be shifted downward 1 logical record, continuing to reference the same
+record as it did before.
+<p>Using the <i>db</i> <b>put</b> or <i>dbc</i> <b>put</b> interfaces to create new records will
+cause the creation of multiple records if the record number is more than one
+greater than the largest record currently in the database. For example,
+creating record 28, when record 25 was previously the last record in the
+database, will create records 26 and 27 as well as 28.
+<p>If a created record is not at the end of the database, all records following
+the new record will be automatically renumbered upward by 1. For example,
+the creation of a new record numbered 8 causes records numbered 8 and
+greater to be renumbered upward by 1. If a cursor was positioned to record
+number 8 or greater before the insertion, it will be shifted upward 1
+logical record, continuing to reference the same record as it did before.
+<p>For these reasons, concurrent access to a Recno database with the
+<b>-renumber</b> flag specified may be largely meaningless, although it
+is supported.
+<p><dt>-snapshot<dd>This argument specifies that any specified <b>-source</b> file be read
+in its entirety when the database is opened. If this argument is not
+specified, the <b>-source</b> file may be read lazily.
+<p><dt>-source file<dd>Set the underlying source file for the Recno access method.  The purpose
+of the <b>-source</b> file is to provide fast access and modification
+to databases that are normally stored as flat text files.
+<p>If the <b>-source</b> argument is give, it specifies an underlying flat
+text database file that is read to initialize a transient record number
+index.  In the case of variable length records, the records are separated
+as specified by <b>-delim</b>.  For example, standard UNIX byte stream
+files can be interpreted as a sequence of variable length records
+separated by &lt;newline&gt; characters.
+<p>In addition, when cached data would normally be written back to the
+underlying database file (e.g., the <i>db</i> <b>close</b> or <i>db</i> <b>sync</b>
+commands are called), the in-memory copy of the database will be written
+back to the <b>-source</b> file.
+<p>By default, the backing source file is read lazily, i.e., records are not
+read from the file until they are requested by the application.
+<b>If multiple processes (not threads) are accessing a Recno database
+concurrently and either inserting or deleting records, the backing source
+file must be read in its entirety before more than a single process
+accesses the database, and only that process should specify the backing
+source argument as part of the <b>berkdb open</b> call.  See the <b>-snapshot</b>
+argument for more information.</b>
+<p><b>Reading and writing the backing source file specified by <b>-source</b>
+cannot be transactionally protected because it involves filesystem
+operations that are not part of the Berkeley DB transaction methodology.</b>
+For this reason, if a temporary database is used to hold the records,
+i.e., no <b>file</b> argument was specified to the <b>berkdb open</b> call,
+it is possible to lose the contents of the <b>-file</b> file, e.g., if
+the system crashes at the right instant.  If a file is used to hold the
+database, i.e., a file name was specified as the <b>file</b> argument
+to <b>berkdb open</b>, normal database recovery on that file can be used to
+prevent information loss, although it is still possible that the contents
+of <b>-source</b> will be lost if the system crashes.
+<p>The <b>-source</b> file must already exist (but may be zero-length) when
+<b>berkdb open</b> is called.
+<p>It is not an error to specify a read-only <b>-source</b> file when
+creating a database, nor is it an error to modify the resulting database.
+However, any attempt to write the changes to the backing source file using
+either the <i>db</i> <b>close</b> or <i>db</i> <b>sync</b> commands will fail, of course.
+Specify the <b>-nosync</b> argument to the <i>db</i> <b>close</b> command will
+stop it from attempting to write the changes to the backing file, instead,
+they will be silently discarded.
+<p>For all of the above reasons, the <b>-source</b> file is generally used
+to specify databases that are read-only for Berkeley DB applications, and that
+are either generated on the fly by software tools, or modified using a
+different mechanism, e.g., a text editor.
+<p><dt>-truncate<dd>Physically truncate the underlying file, discarding all previous databases
+it might have held.  Underlying filesystem primitives are used to
+implement this flag.  For this reason it is only applicable to the
+physical file and cannot be used to discard databases within a file.
+<p>The <b>-truncate</b> argument cannot be transaction protected, and it is
+an error to specify it in a transaction protected environment.
+<p><dt>-upgrade<dd>Upgrade the database represented by <b>file</b>, if necessary.
+<p><b>Note: Database upgrades are done in place and are
+destructive, e.g., if pages need to be allocated and no disk space is
+available, the database may be left corrupted.  Backups should be made
+before databases are upgraded.  See <a href="../ref/am/upgrade.html">Upgrading databases</a> for more information.</b>
+<p><dt>--<dd>Mark the end of the command arguments.
+<p><dt>file<dd>The name of a single physical file on disk that will be used to back the
+database.
+<p><dt>database<dd>The <b>database</b> argument allows applications to have multiple
+databases inside of a single physical file.  This is useful when the
+databases are both numerous and reasonably small, in order to avoid
+creating a large number of underlying files.  It is an error to attempt
+to open a second database file that was not initially created using a
+<b>database</b> name.
+</dl>
+<p>The <b>berkdb open</b> command returns a database handle on success.
+<p>In the case of error, a Tcl error is thrown.

+<p>If the database is empty, <i>dbc</i> <b>get</b> will return an empty list.
+<p><dt>-next<dd>If the cursor is not yet initialized, the <b>-next</b> option is
+identical to <b>-first</b>.
+<p>Otherwise, the cursor is moved to the next key/data pair of the database,
+and that pair is returned. In the presence of duplicate key values, the
+value of the key may not change. 
+<p>If the database is a Queue or Recno database, <i>dbc</i> <b>get</b> using the
+<b>-next</b> option will skip any keys that exist but were never
+explicitly created by the application or were created and later deleted.
+<p>If the cursor is already on the last record in the database, <i>dbc</i> <b>get</b>
+will return an empty list.
+<p><dt>-nextdup<dd>If the next key/data pair of the database is a duplicate record for the

+an empty list.
+<p><dt>-nextnodup<dd>If the cursor is not yet initialized, the <b>-nextnodup</b> option is
+identical to <b>-first</b>.
+<p>Otherwise, the cursor is moved to the next non-duplicate
+key/data pair of the database, and that pair is returned.
+<p>If no non-duplicate key/data pairs occur after the cursor
+position in the database, <i>dbc</i> <b>get</b> will return an empty list.
+<p><dt>-prev<dd>If the cursor is not yet initialized, <b>-prev</b> is identical to
+<b>-last</b>.
+<p>Otherwise, the cursor is moved to the previous key/data pair of the
+database, and that pair is returned. In the presence of duplicate key
+values, the value of the key may not change.
+<p>If the database is a Queue or Recno database, <i>dbc</i> <b>get</b> using the
+<b>-prev</b> flag will skip any keys that exist but were never explicitly
+created by the application or were created and later deleted.
+<p>If the cursor is already on the first record in the database,
+<i>dbc</i> <b>get</b> will return an empty list.
+<p><dt>-prevnodup<dd>If the cursor is not yet initialized, the <b>-prevnodup</b> option is
+identical to <b>-last</b>.
+<p>Otherwise, the cursor is moved to the previous non-duplicate

+<p>If no non-duplicate key/data pairs occur before the cursor
+position in the database, <i>dbc</i> <b>get</b> will return an empty list.
+<p><dt>-set<dd>Move the cursor to the specified key/data pair of the database, and return

+<i>dbc</i> <b>get</b> will return an empty list.
+<p>If no matching keys are found, <i>dbc</i> <b>get</b> will return an empty list.
+<p><dt>-set_range<dd>The <b>-set_range</b> option is identical to the <b>-set</b> option,
+except that the key is returned as well as the data item, and, in the case
+of the Btree access method, the returned key/data pair is the smallest
+key greater than or equal to the specified key (as determined by the
+comparison function), permitting partial key matches and range searches.
+<p><dt>-get_both<dd>The <b>-get_both</b> option is identical to the <b>-set</b> option,
+except that both the key and the data arguments must be matched by the
+key and data item in the database.
+<p>For <b>-get_both</b> to be specified, the underlying database must be of
+type Btree or Hash.
+<p><dt>-set_recno<dd>Move the cursor to the specific numbered record of the database, and
+return the associated key/data pair. The key
+must be a record number.
+<p>For the <b>-set_recno</b> option to be specified, the underlying database
+must be of type Btree and it must have been created with the <b>-recnum</b>
+option.
+<p><dt>-get_recno<dd>Return a list of the record number associated with the current cursor
+position.  No key argument should be specified.
+<p>For <b>-get_recno</b> to be specified, the underlying database must be
+of type Btree and it must have been created with the <b>-recnum</b>
+option.
+<p><dt>-join_item<dd>Do not use the data value found in all of the cursors as a lookup key for
+the primary database, but simply return it in the key parameter instead.
+The data parameter is left unchanged.
+<p>For <b>-join_item</b> to be specified, the cursor must have been created
+by the <i>db</i> <b>join</b> command.
+<p><dt>-partial {offset length}<dd>The <b>dlen</b> bytes starting <b>doff</b> bytes from the beginning of
+the retrieved data record are returned as if they comprised the entire
+record. If any or all of the specified bytes do not exist in the record,
+the command is successful and the existing bytes or 0 bytes are
+returned.
+<p><dt>-rmw<dd>Acquire write locks instead of read locks when doing the retrieval. Setting
+this flag may decrease the likelihood of deadlock during a read-modify-write
+cycle by immediately acquiring the write lock during the read part of the
+cycle so that another thread of control acquiring a read lock for the same
+item, in its own read-modify-write cycle, will not result in deadlock.
+</dl>
+<p>If a key is specified, and
+if the underlying database is a Queue or Recno database, then the given
+key will be interpreted by Tcl as an integer.  For all other database
+types, the key is interpreted by Tcl as a byte array unless indicated
+by a given option.
+<p>In the normal error case of attempting to retrieve a key that does not
+exist an empty list is returned.
+<p>In the case of error, a Tcl error is thrown.

+<h1>Description</h1>
+<p>The <b>berkdb env</b> command opens, and optionally creates, a database
+environment.  The returned environment handle is bound to a Tcl command
+of the form <b>envN</b>, where N is an integer starting at 0 (e.g., env0
+and env1).  It is through this Tcl command that the script accesses the
+environment methods.
+The command automatically initializes the shared memory buffer pool subsystem.
+This subsystem is used whenever the application is
+using any Berkeley DB access method.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt>-cachesize {gbytes bytes ncache}<dd>Set the size of the database's shared memory buffer pool, i.e., the cache,
+to <b>gbytes</b> gigabytes plus <b>bytes</b>.  The cache should be the
+size of the normal working data set of the application, with some small
+amount of additional memory for unusual situations.  (Note, the working
+set is not the same as the number of simultaneously referenced pages, and
+should be quite a bit larger!)
+<p>The default cache size is 256KB, and may not be specified as less than
+20KB.  Any cache size less than 500MB is automatically increased by 25%
+to account for buffer pool overhead, cache sizes larger than 500MB are
+used as specified.
+<p>It is possible to specify caches to Berkeley DB that are large enough so that
+they cannot be allocated contiguously on some architectures, e.g., some
+releases of Solaris limit the amount of memory that may be allocated
+contiguously by a process.  If <b>ncache</b> is 0 or 1, the cache will
+be allocated contiguously in memory.  If it is greater than 1, the cache
+will be broken up into <b>ncache</b> equally sized separate pieces of
+memory.
+<p>For information on tuning the Berkeley DB cache size, see
+<a href="../ref/am_conf/cachesize.html">Selecting a cache size</a>.
+<p><dt>-create<dd>Cause Berkeley DB subsystems to create any underlying files, as necessary.
+<p><dt>-data_dir dirname<dd>Specify the environment's data directory as described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p><dt>-errfile filename<dd>
+<p>When an error occurs in the Berkeley DB library, a Berkeley DB error or an error
+return value is returned by the function. In some cases, however, the
+errno value may be insufficient to completely describe the cause of the
+error especially during initial application debugging.
+<p>The <b>-errfile</b> argument is used to enhance the mechanism for
+reporting error messages to the application by specifying a file to be
+used for displaying additional Berkeley DB error messages. In some cases, when
+an error occurs, Berkeley DB will output an additional error message to the
+specified file reference.
+<p>The error message will consist of the environment command name (e.g., env0)
+and a colon (":"), an error string, and a trailing &lt;newline&gt;
+character.
+<p>This error logging enhancement does not slow performance or significantly
+increase application size, and may be run during normal operation as well
+as during application debugging.
+<p><dt>-home directory<dd>The <b>-home</b> argument is described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p><dt>-log_dir dirname<dd>Specify the environment's logging file directory as described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p><dt>-mode mode<dd>
+<p>On UNIX systems, or in IEEE/ANSI Std 1003.1 (POSIX) environments, all files created by Berkeley DB
+are created with mode <b>mode</b> (as described in <b>chmod</b>(2)) and
+modified by the process' umask value at the time of creation (see
+<b>umask</b>(2)).  The group ownership of created files is based on
+the system and directory defaults, and is not further specified by Berkeley DB.
+If <b>mode</b> is 0, files are created readable and writeable by both
+owner and group.  On Windows systems, the mode argument is ignored.
+<p><dt>-private<dd>Specify that the environment will only be accessed by a single process
+(although that process may be multi-threaded).  This flag has two effects
+on the Berkeley DB environment.  First, all underlying data structures are
+allocated from per-process memory instead of from shared memory that is
+potentially accessible to more than a single process.  Second, mutexes
+are only configured to work between threads.
+<p>This flag should not be specified if more than a single process is
+accessing the environment, as it is likely to cause database corruption
+and unpredictable behavior, e.g., if both a server application and the
+Berkeley DB utility <a href="../utility/db_stat.html">db_stat</a> will access the environment, the
+<b>-private</b> option should not be specified.
+<p><dt>-recover<dd>Run normal recovery on this environment before opening it for normal use.
+If this flag is set, the <b>-create</b> option must also be set since
+the regions will be removed and recreated.
+<p><dt>-recover_fatal<dd>Run catastrophic recovery on this environment before opening it for
+normal use.  If this flag is set, the <b>-create</b> option must also be
+set since the regions will be removed and recreated.
+<p><dt>-shm_key key<dd>Specify a base segment ID for Berkeley DB environment shared memory regions
+created in system memory on systems supporting X/Open-style shared memory
+interfaces, e.g., UNIX systems supporting shmget(2) and related System V
+IPC interfaces.  See <a href="../ref/env/region.html">Shared Memory
+Regions</a> for more information.
+<p><dt>-system_mem<dd>Allocate memory from system shared memory instead of memory backed by the
+filesystem.  See <a href="../ref/env/region.html">Shared Memory Regions</a>
+for more information.
+<p><dt>-tmp_dir dirname<dd>Specify the environment's tmp directory as described in
+<a href="../ref/env/naming.html">Berkeley DB File Naming</a>.
+<p><dt>-txn [nosync]<dd>Initialize the transaction subsystem.  This subsystem is used when
+recovery and atomicity of multiple operations and recovery are important.
+The <b>-txn</b> option implies the initialization of the logging
+and locking subsystems as well.
+<p>If the optional <b>nosync</b> argument is specified, the log will not be
+synchronously flushed on transaction commit or prepare.  This means that
+transactions exhibit the ACI (atomicity, consistency and isolation)
+properties, but not D (durability), i.e., database integrity will be
+maintained but it is possible that some number of the most recently
+committed transactions may be undone during recovery instead of being
+redone.
+<p>The number of transactions that are potentially at risk is governed by
+how often the log is checkpointed (see <a href="../utility/db_checkpoint.html">db_checkpoint</a> for more
+information) and how many log updates can fit on a single log page.
+<p><dt>-txn_max max<dd>Set the maximum number of simultaneous transactions that are supported
+by the environment.  This bounds the size of backing files.  When there
+are more than the specified number of concurrent transactions, calls to
+<i>env</i> <b>txn</b> will fail (until some active transactions complete).
+<p><dt>-use_environ<dd>The Berkeley DB process' environment may be permitted to specify information to
+be used when naming files; see <a href="../ref/env/naming.html">Berkeley DB
+File Naming</a>.  As permitting users to specify which files are used can
+create security problems, environment information will be used in file
+naming for all users only if the <b>-use_environ</b> flag is set.
+<p><dt>-use_environ_root<dd>The Berkeley DB process' environment may be permitted to specify information
+to be used when naming files; see <a href="../ref/env/naming.html">Berkeley DB
+File Naming</a>.  As permitting users to specify which files are used can
+create security problems, if the <b>-use_environ_root</b> flag is set,
+environment information will be used for file naming only for users with
+appropriate permissions (e.g., on IEEE/ANSI Std 1003.1 (POSIX) systems, users with a
+user-ID of 0).
+</dl>
+<p>The <b>berkdb env</b> command returns an environment handle on success.
+<p>In the case of error, a Tcl error is thrown.

+<p>The <i>txn</i> <b>commit</b> command ends the transaction. 
+<p>In the case of nested transactions, if the transaction is a parent
+transaction with unresolved (neither committed or aborted) child
+transactions, the child transactions are aborted and the commit of the
+parent will succeed.
+<p>In the case of nested transactions, if the transaction is a child
+transaction, its locks are not released, but are acquired by its parent.
+While the commit of the child transaction will succeed, the actual
+resolution of the child transaction is postponed until the parent
+transaction is committed or aborted, i.e., if its parent transaction
+commits, it will be committed, and if its parent transaction aborts, it
+will be aborted.
+<p>If the <b>-nosync</b> option is not specified, a commit log record is
+written and flushed to disk, as are all previously written log records.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt>-nosync<dd>Do not synchronously flush the log. This means the transaction will
+exhibit the ACI (atomicity, consistency and isolation) properties, but

+<b>It is important to understand that flushing cached information

+<p>While unlikely, it is possible for database corruption to happen if a
+system or application crash occurs while writing data to the database. To
+ensure that database corruption never occurs, applications must either:
+<ul type=disc>
+<li>Use transactions and logging with automatic recovery.
+<li>Use logging and application-specific recovery.
+<li>Edit a copy of the database, and, once all applications
+using the database have successfully called <a href="../../api_c/db_close.html">DB-&gt;close</a>, use
+system operations (e.g., the POSIX rename system call) to atomically
+replace the original database with the updated copy.

+<h1 align=center>Retrieving records with a cursor</h1>
+<p>The <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a> function is the standard interface for retrieving records from
+the database with a cursor.  The <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a> function takes a flag which
+controls how the cursor is positioned within the database and returns the
+key/data item associated with that positioning.  Similar to
+<a href="../../api_c/db_get.html">DB-&gt;get</a>, <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a> may also take a supplied key and retrieve
+the data associated with that key from the database.  There are several
+flags that you can set to customize retrieval.
+<h3>Cursor position flags</h3>
+<p><dl compact>
+<p><dt><a href="../../api_c/dbc_get.html#DB_FIRST">DB_FIRST</a>, <a href="../../api_c/dbc_get.html#DB_LAST">DB_LAST</a><dd>Return the first (last) record in the database.

+<p><dt><a href="../../api_c/dbc_get.html#DB_NEXT_DUP">DB_NEXT_DUP</a><dd>Return the next record in the database, if it is a duplicate data item
+for the current key.

+duplicate data item for the current key.
+<p><dt><a href="../../api_c/dbc_get.html#DB_CURRENT">DB_CURRENT</a><dd>Return the record from the database currently referenced by the

+</dl>
+<h3>Retrieving specific key/data pairs</h3>
+<p><dl compact>
+<p><dt><a href="../../api_c/dbc_get.html#DB_SET">DB_SET</a><dd>Return the record from the database that matches the supplied key.  In
+the case of duplicates the first duplicate is returned and the cursor
+is positioned at the beginning of the duplicate list.  The user can then
+traverse the duplicate entries for the key.
+<p><dt><a href="../../api_c/dbc_get.html#DB_SET_RANGE">DB_SET_RANGE</a><dd>Return the smallest record in the database greater than or equal to the
+supplied key.  This functionality permits partial key matches and range
+searches in the Btree access method.
+<p><dt><a href="../../api_c/db_get.html#DB_GET_BOTH">DB_GET_BOTH</a><dd>Return the record from the database that matches both the supplied key
+and data items.  This is particularly useful when there are large
+numbers of duplicate records for a key, as it allows the cursor to
+easily be positioned at the correct place for traversal of some part of
+a large set of duplicate records.
+</dl>
+<h3>Retrieving based on record numbers</h3>
+<p><dl compact>
+<p><dt><a href="../../api_c/db_get.html#DB_SET_RECNO">DB_SET_RECNO</a><dd>If the underlying database is a Btree, and was configured so that it is
+possible to search it by logical record number, retrieve a specific

+possible to search it by logical record number, return the record number
+for the record referenced by the cursor.
+</dl>
+<h3>Special-purpose flags</h3>
+<p><dl compact>
+<p><dt><a href="../../api_c/db_get.html#DB_CONSUME">DB_CONSUME</a><dd>Read-and-delete: the first record (the head) of the queue is returned and

+<p><dt><a href="../../api_c/dbc_get.html#DB_RMW">DB_RMW</a><dd>Read-modify-write: acquire write locks instead of read locks during
+retrieval. This can enhance performance in threaded applications by

+</dl>

+<h1 align=center>Error support</h1>
+<p>Berkeley DB offers programmatic support for displaying error return values.
+<p>The <a href="../../api_c/env_strerror.html">db_strerror</a> interface returns a pointer to the error
+message corresponding to any Berkeley DB error return, similar to the ANSI C
+strerror interface, but is able to handle both system error returns and
+Berkeley DB specific return values.
+<p>For example:
+<p><blockquote><pre>int ret;
+if ((ret = dbp-&gt;put(dbp, NULL, &key, &data, 0)) != 0) {
+	fprintf(stderr, "put failed: %s\n", db_strerror(ret));
+	return (1);
+}
+</pre></blockquote>
+<p>There are also two additional error interfaces, <a href="../../api_c/db_err.html">DB-&gt;err</a> and
+<a href="../../api_c/db_err.html">DB-&gt;errx</a>.  These interfaces work like the ANSI C X3.159-1989 (ANSI C) printf
+interface, taking a printf-style format string and argument list, and
+writing a message constructed from the format string and arguments.
+<p>The <a href="../../api_c/db_err.html">DB-&gt;err</a> function appends the standard error string to the constructed
+message, the <a href="../../api_c/db_err.html">DB-&gt;errx</a> function does not.  These interfaces provide simpler
+ways of displaying Berkeley DB error messages.  For example, if your application
+tracks session IDs in a variable called session_id, it can include that
+information in its error messages:
+<p>Error messages can additionally be configured to always include a prefix
+(e.g., the program name) using the <a href="../../api_c/db_set_errpfx.html">DB-&gt;set_errpfx</a> interface.
+<p><blockquote><pre>#define DATABASE "access.db"
+int ret;
+dbp-&gt;errpfx(dbp, argv0);
+if ((ret =
+	dbp-&gt;open(dbp, DATABASE, DB_BTREE, DB_CREATE, 0664)) != 0) {
+	dbp-&gt;err(dbp, ret, "%s", DATABASE);
+	dbp-&gt;errx(dbp,
+		"contact your system administrator: session ID was %d",
+    		session_id);
+	return (1);
+}
+</pre></blockquote>
+<p>For example, if the program was called my_app, and the open call returned
+an EACCESS system error, the error messages shown would appear as follows:
+<p><blockquote><pre>my_app: access.db: Permission denied.
+my_app: contact your system administrator: session ID was 14</pre></blockquote>

+<h1 align=center>Logical join</h1>
+<p>A logical join is a method of retrieving data from a primary database
+using criteria stored in a set of secondary indexes.  A logical join
+requires that your data be organized as a primary database which
+contains the primary key and primary data field, and a set of secondary
+indexes.  Each of the secondary indexes is indexed by a different
+secondary key, and, for each key in a secondary index, there is a set
+of duplicate data items that match the primary keys in the primary
+database.
+<p>For example, let's assume the need for an application that will return
+the names of stores in which one can buy fruit of a given color.  We
+would first construct a primary database that lists types of fruit as
+the key item, and the store where you can buy them as the data item:
+<p><blockquote><pre><b>Primary key:</b>		<b>Primary data:</b>
+apple		Convenience Store
+blueberry	Farmer's Market
+peach		Shopway
+pear		Farmer's Market
+raspberry	Shopway
+strawberry	Farmer's Market</pre></blockquote>
+<p>We would then create a secondary index with the key <b>color</b>, and,
+as the data items, the names of fruits of different colors.
+<p><blockquote><pre><b>Secondary key:</b>		<b>Secondary data:</b>
+blue		blueberry
+red		apple
+red		raspberry
+red		strawberry
+yellow		peach
+yellow		pear</pre></blockquote>
+<p>This secondary index would allow an application to look up a color, and
+then use the data items to look up the stores where the colored fruit
+could be purchased.  For example, by first looking up <b>blue</b>,
+the data item <b>blueberry</b> could be used as the lookup key in the
+primary database, returning <b>Farmer's Market</b>.
+<p>Your data must be organized in the following manner in order to use the
+<a href="../../api_c/db_join.html">DB-&gt;join</a> function:
+<p><ol>
+<p><li>The actual data should be stored in the database represented by the
+DB object used to invoke this function.  Generally, this
+DB object is called the <i>primary</i>.
+<p><li>Secondary indexes should be stored in separate databases, whose keys
+are the values of the secondary indexes and whose data items are the
+primary keys corresponding to the records having the designated
+secondary key value.  It is acceptable (and expected) that there may be
+duplicate entries in the secondary indexes.
+<p>These duplicate entries should be sorted for performance reasons, although
+it is not required.  For more information see the <a href="../../api_c/db_set_flags.html#DB_DUPSORT">DB_DUPSORT</a> flag
+to the <a href="../../api_c/db_set_flags.html">DB-&gt;set_flags</a> function.
+</ol>
+<p>What the <a href="../../api_c/db_join.html">DB-&gt;join</a> function does is review a list of secondary keys, and,
+when it finds a data item that appears as a data item for all of the
+secondary keys, it uses that data items as a lookup into the primary
+database, and returns the associated data item.
+<p>If there were a another secondary index that had as its key the
+<b>cost</b> of the fruit, a similar lookup could be done on stores
+where inexpensive fruit could be purchased:
+<p><blockquote><pre><b>Secondary key:</b>		<b>Secondary data:</b>
+expensive	blueberry
+expensive	peach
+expensive	pear
+expensive	strawberry
+inexpensive	apple
+inexpensive	pear
+inexpensive	raspberry</pre></blockquote>
+<p>The <a href="../../api_c/db_join.html">DB-&gt;join</a> function provides logical join functionality.  While not
+strictly cursor functionality, in that it is not a method off a cursor
+handle, it is more closely related to the cursor operations than to the
+standard DB operations.
+<p>It is also possible to do lookups based on multiple criteria in a single
+operation, e.g., it is possible to look up fruits that are both red and
+expensive in a single operation.  If the same fruit appeared as a data
+item in both the color and expense indexes, then that fruit name would
+be used as the key for retrieval from the primary index, and would then
+return the store where expensive, red fruit could be purchased.
+<h3>Example</h3>
+<p>Consider the following three databases:
+<p><dl compact>
+<p><dt>personnel<dd><ul type=disc>
+<li>key = SSN
+<li>data = record containing name, address, phone number, job title
+</ul>
+<p><dt>lastname<dd><ul type=disc>
+<li>key = lastname
+<li>data = SSN
+</ul>
+<p><dt>jobs<dd><ul type=disc>
+<li>key = job title
+<li>data = SSN
+</ul>
+</dl>
+<p>Consider the following query:
+<p><blockquote><pre>Return the personnel records of all people named smith with the job
+title manager.</pre></blockquote>
+<p>This query finds are all the records in the primary database (personnel)
+for whom the criteria <b>lastname=smith and job title=manager</b> is
+true.
+<p>Assume that all databases have been properly opened and have the handles:
+pers_db, name_db, job_db.  We also assume that we have an active
+transaction referenced by the handle txn.
+<p><blockquote><pre>DBC *name_curs, *job_curs, *join_curs;
+DBC *carray[3];
+DBT key, data;
+int ret, tret;
+<p>
+name_curs = NULL;
+job_curs = NULL;

+<p>

+	goto err;
+key.data = "smith";
+key.size = sizeof("smith");
+if ((ret =
+    name_curs-&gt;c_get(name_curs, &key, &data, DB_SET)) != 0)
+	goto err;
+<p>
+if ((ret = job_db-&gt;cursor(job_db, txn, &job_curs)) != 0)
+	goto err;
+key.data = "manager";
+key.size = sizeof("manager");
+if ((ret =
+    job_curs-&gt;c_get(job_curs, &key, &data, DB_SET)) != 0)
+	goto err;
+<p>
+carray[0] = name_curs;
+carray[1] = job_curs;
+carray[2] = NULL;
+<p>
+if ((ret =
+    pers_db-&gt;join(pers_db, carray, &join_curs, 0)) != 0)
+	goto err;
+while ((ret =
+    join_curs-&gt;c_get(join_curs, &key, &data, 0)) == 0) {
+	/* Process record returned in key/data. */
+}
+<p>
+/*
+ * If we exited the loop because we ran out of records,
+ * then it has completed successfully.
+ */
+if (ret == DB_NOTFOUND)
+	ret = 0;
+<p>
+err:
+if (join_curs != NULL &&
+    (tret = join_curs-&gt;c_close(join_curs)) != 0 && ret == 0)
+	ret = tret;
+if (name_curs != NULL &&
+    (tret = name_curs-&gt;c_close(name_curs)) != 0 && ret == 0)
+	ret = tret;
+if (job_curs != NULL &&
+    (tret = job_curs-&gt;c_close(job_curs)) != 0 && ret == 0)
+	ret = tret;
+<p>
+return (ret);
+</pre></blockquote>
+<p>The name cursor is positioned at the beginning of the duplicate list
+for <b>smith</b> and the job cursor is placed at the beginning of
+the duplicate list for <b>manager</b>.  The join cursor is returned
+from the logical join call.  This code then loops over the join cursor
+getting the personnel records of each one until there are no more.

+<h1 align=center>Opening multiple databases in a single file</h1>
+<p>Applications may create multiple databases within a single physical
+file.  This is useful when the databases are both numerous and
+reasonably small, in order to avoid creating a large number of
+underlying files, or when it is desirable to include secondary index
+databases in the same file as the primary index database.  Multiple
+databases are an administrative convenience and using them is unlikely
+to effect database performance.  To open or create a file that will
+include more than a single database, specify a database name when
+calling the <a href="../../api_c/db_open.html">DB-&gt;open</a> method.
+<p>Physical files do not need to be comprised of a single type of database,
+and databases in a file may be of any type (e.g., Btree, Hash or Recno),
+except for Queue databases.  Queue databases must be created one per file
+and cannot share a file with any other database type.  There is no limit
+on the number of databases that may be created in a single file other than
+the standard Berkeley DB file size and disk space limitations.
+<p>It is an error to attempt to open a second database in a file that was
+not initially created using a database name, that is, the file must
+initially be specified as capable of containing multiple databases for a
+second database to be created in it.
+<p>It is not an error to open a file that contains multiple databases without
+specifying a database name, however the database type should be specified
+as DB_UNKNOWN and the database must be opened read-only.  The handle that
+is returned from such a call is a handle on a database whose key values
+are the names of the databases stored in the database file and whose data
+values are opaque objects.  No keys or data values may be modified or
+stored using this database handle.
+<p>Storing multiple databases in a single file is almost identical to
+storing each database in its own separate file.  The one crucial
+difference is how locking and the underlying memory pool services must
+to be configured.  As an example, consider two databases instantiated
+in two different physical files.  If access to each separate database
+is single-threaded, there is no reason to perform any locking of any
+kind, and the two databases may be read and written simultaneously.
+Further, there would be no requirement to create a shared database
+environment in which to open the databases.  Because multiple databases
+in a file exist in a single physical file, opening two databases in the
+same file requires that locking be enabled, unless access to the
+databases is known to be single-threaded, that is, only one of the
+databases is ever accessed at a time.  (As the locks for the two
+databases can only conflict during page allocation, this additional
+locking is unlikely to effect performance.)  Further, the databases must
+share an underlying memory pool so that per-physical-file information
+is updated correctly.

+<h1 align=center>Partial record storage and retrieval</h1>
+<p>It is possible to both store and retrieve parts of data items in all
+Berkeley DB access methods.  This is done by setting the
+<a href="../../api_c/dbt.html#DB_DBT_PARTIAL">DB_DBT_PARTIAL</a> flag in the <a href="../../api_c/dbt.html">DBT</a> structure passed to the
+Berkeley DB interface.
+<p>The <a href="../../api_c/dbt.html#DB_DBT_PARTIAL">DB_DBT_PARTIAL</a> flag is based on the values of two fields
+of the <a href="../../api_c/dbt.html">DBT</a> structure, <b>dlen</b> and <b>doff</b>.  The value
+of <b>dlen</b> is the number of bytes of the record in which the
+application is interested.  The value of <b>doff</b> is the offset from
+the beginning of the data item where those bytes start.
+<p>For example, if the data item were <b>ABCDEFGHIJKL</b>, a <b>doff</b>
+value of 3 would indicate that the bytes of interest started at
+<b>D</b>, and a <b>dlen</b> value of 4 would indicate that the bytes
+of interest were <b>DEFG</b>.
+<p>When retrieving a data item from a database, the <b>dlen</b> bytes
+starting <b>doff</b> bytes from the beginning of the record are
+returned, as if they comprised the entire record.  If any or all of the
+specified bytes do not exist in the record, the retrieval is still
+successful and any existing bytes (and nul bytes for any non-existent
+bytes) are returned.
+<p>When storing a data item into the database, the <b>dlen</b> bytes
+starting <b>doff</b> bytes from the beginning of the specified key's
+data record are replaced by the data specified by the <b>data</b> and
+<b>size</b> fields.  If <b>dlen</b> is smaller than <b>size</b>, the
+record will grow, and if <b>dlen</b> is larger than <b>size</b>, the
+record will shrink. If the specified bytes do not exist, the record will
+be extended using nul bytes as necessary, and the store call will still
+succeed.
+<p>The following are various examples of the put case for the
+<a href="../../api_c/dbt.html#DB_DBT_PARTIAL">DB_DBT_PARTIAL</a> flag. In all examples, the initial data item is 20
+bytes in length:

+<h1 align=center>Cursor Stability</h1>
+<p>In the absence of locking, no guarantees are made about the stability of
+cursors in different processes or threads.  However, the Btree, Queue
+and Recno access methods guarantee that cursor operations, interspersed
+with other cursor or non-cursor operations in the same thread of control
+will always return keys in order and will return each non-deleted key/data
+pair exactly once.  Because the Hash access method uses a dynamic hashing
+algorithm, it cannot guarantee any form of stability in the presence of
+inserts and deletes unless locking is performed.
+<p>If locking was specified when the Berkeley DB file was opened, but transactions
+are not in effect, the access methods provide repeatable reads with
+respect to the cursor.  That is, a <a href="../../api_c/dbc_get.html#DB_CURRENT">DB_CURRENT</a> call on the cursor
+is guaranteed to return the same record as was returned on the last call
+to the cursor.
+<p>With the exception of the Queue access method, in the presence of
+transactions, all access method calls between a call to <a href="../../api_c/txn_begin.html">txn_begin</a>
+and a call to <a href="../../api_c/txn_abort.html">txn_abort</a> or <a href="../../api_c/txn_commit.html">txn_commit</a> provide degree 3
+consistency (serializable transactions).
+<p>The Queue access method permits phantom records to appear between calls.
+That is, deleted records are not locked, therefore another transaction may
+replace a deleted record between two calls to retrieve it.  The record would
+not appear in the first call but would be seen by the second call.
+<p>For all access methods, a cursor scan of the database performed within
+the context of a transaction is guaranteed to return each key/data pair
+once and only once, except in the following case.  If, while performing
+a cursor scan using the Hash access method, the transaction performing
+the scan inserts a new pair into the database, it is possible that duplicate
+key/data pairs will be returned.

+<h1 align=center>Database verification and salvage</h1>
+<p>The <a href="../../api_c/db_verify.html">DB-&gt;verify</a> method is the standard interface for verifying
+that a file, and any databases it may contain, are uncorrupted.  In
+addition, the method may optionally be called with a file stream
+argument to which all key/data pairs found in the database are output.
+There are two modes for finding key/data pairs to be output:
+<p><ol>
+<p><li>If the <a href="../../api_c/db_verify.html#DB_SALVAGE">DB_SALVAGE</a> flag is specified, the key/data pairs in the
+database are output.  When run in this mode, the database is assumed to
+be largely uncorrupted. For example, the <a href="../../api_c/db_verify.html">DB-&gt;verify</a> method will
+search for pages that are no longer linked into the database, and will
+output key/data pairs from such pages.  However, key/data items that
+have been marked as deleted in the database will not be output, as the
+page structures are generally trusted in this mode.
+<p><li>If both the <a href="../../api_c/db_verify.html#DB_SALVAGE">DB_SALVAGE</a> and <a href="../../api_c/db_verify.html#DB_AGGRESSIVE">DB_AGGRESSIVE</a> flags are
+specified, all possible key/data pairs are output.  When run in this mode,
+the database is assumed to be seriously corrupted.  For example, key/data
+pairs that have been deleted will re-appear in the output.  In addition,
+because pages may have been subsequently re-used and modified during
+normal database operations after the key/data pairs were deleted, it is
+not uncommon for apparently corrupted key/data pairs to be output in this
+mode, even when there is no corruption in the underlying database.  The
+output will almost always have to be edited by hand or other means before
+the data is ready for re-load into another database.  We recommend that
+<a href="../../api_c/db_verify.html#DB_SALVAGE">DB_SALVAGE</a> be tried first, and <a href="../../api_c/db_verify.html#DB_AGGRESSIVE">DB_AGGRESSIVE</a> only tried
+if the output from that first attempt is obviously missing data items or
+the data is sufficiently valuable that human review of the output is
+preferable to any kind of data loss.

+<h1 align=center>Btree comparison</h1>
+<p>The Btree data structure is a sorted, balanced tree structure storing
+associated key/data pairs.  By default, the sort order is lexicographical,
+with shorter keys collating before longer keys.  The user can specify the
+sort order for the Btree by using the <a href="../../api_c/db_set_bt_compare.html">DB-&gt;set_bt_compare</a> function.
+<p>Sort routines are passed pointers to keys as arguments.  The keys are
+represented as <a href="../../api_c/dbt.html">DBT</a> structures.  The routine must return an integer
+less than, equal to, or greater than zero if the first argument is
+considered to be respectively less than, equal to, or greater than the
+second argument.  The only fields that the routines may examine in the
+<a href="../../api_c/dbt.html">DBT</a> structures are <b>data</b> and <b>size</b> fields.
+<p>An example routine that might be used to sort integer keys in the database
+is as follows:
+<p><blockquote><pre>int
+compare_int(dbp, a, b)
+	DB *dbp;
+	const DBT *a, *b;
+{
+	int ai, bi;
+<p>
+	/*
+	 * Returns:
+	 *	&lt; 0 if a &lt; b
+	 *	= 0 if a = b
+	 *	&gt; 0 if a &gt; b
+	 */
+	memcpy(&ai, a-&gt;data, sizeof(int));
+	memcpy(&bi, b-&gt;data, sizeof(int));
+	return (ai - bi);
+}
+</pre></blockquote>
+<p>Note that the data must first be copied into memory that is appropriately
+aligned, as Berkeley DB does not guarantee any kind of alignment of the
+underlying data, including for comparison routines.  When writing
+comparison routines, remember that databases created on machines of
+different architectures may have different integer byte orders, for which
+your code may need to compensate.
+<p>An example routine that might be used to sort keys based on the first
+five bytes of the key (ignoring any subsequent bytes) is as follows:
+<p><blockquote><pre>int
+compare_dbt(dbp, a, b)
+	DB *dbp;
+	const DBT *a, *b;
+{
+	u_char *p1, *p2;
+<p>
+	/*
+	 * Returns:
+	 *	&lt; 0 if a &lt; b
+	 *	= 0 if a = b
+	 *	&gt; 0 if a &gt; b
+	 */
+	for (p1 = a-&gt;data, p2 = b-&gt;data, len = 5; len--; ++p1, ++p2)
+		if (*p1 != *p2)
+			return ((long)*p1 - (long)*p2);
+	return (0);
+}</pre></blockquote>
+<p>All comparison functions must cause the keys in the database to be
+well-ordered. The most important implication of being well-ordered is
+that the key relations must be transitive, that is, if key A is less
+than key B, and key B is less than key C, then the comparison routine
+must also return that key A is less than key C. In addition, comparisons
+will only be able to return 0 when comparing full length keys; partial
+key comparisons must always return a result less than or greater than 0.

+<h1 align=center>Minimum keys per page</h1>
+<p>The number of keys stored on each page affects the size of a Btree and
+how it is maintained.  Therefore, it also affects the retrieval and search
+performance of the tree.  For each Btree, Berkeley DB computes a maximum key
+and data size.  This size is a function of the page size and the fact that
+at least two key/data pairs must fit on any Btree page.  Whenever key or
+data items exceed the calculated size, they are stored on overflow pages
+instead of in the standard Btree leaf pages.
+<p>Applications may use the <a href="../../api_c/db_set_bt_minkey.html">DB-&gt;set_bt_minkey</a> function to change the minimum
+number of keys that must fit on a Btree page from two to another value.
+Altering this value in turn alters the on-page maximum size, and can be
+used to force key and data items which would normally be stored in the
+Btree leaf pages onto overflow pages.
+<p>Some data sets can benefit from this tuning.  For example, consider an
+application using large page sizes, with a data set almost entirely
+consisting of small key and data items, but with a few large items.  By
+setting the minimum number of keys that must fit on a page, the
+application can force the outsized items to be stored on overflow pages.
+That in turn can potentially keep the tree more compact, that is, with
+fewer internal levels to traverse during searches.
+<p>The following calculation is similar to the one performed by the Btree
+implementation.  (The <b>minimum_keys</b> value is multiplied by 2
+because each key/data pair requires 2 slots on a Btree page.)
+<p><blockquote><pre>maximum_size = page_size / (minimum_keys * 2)</pre></blockquote>
+<p>Using this calculation, if the page size is 8KB and the default
+<b>minimum_keys</b> value of 2 is used, then any key or data items
+larger than 2KB will be forced to an overflow page.  If an application
+were to specify a <b>minimum_key</b> value of 100, then any key or data
+items larger than roughly 40 bytes would be forced to overflow pages.
+<p>It is important to remember that accesses to overflow pages do not perform
+as well as accesses to the standard Btree leaf pages, and so setting the
+value incorrectly can result in overusing overflow pages and decreasing
+the application's overall performance.

+<h1 align=center>Btree prefix comparison</h1>
+<p>The Berkeley DB Btree implementation maximizes the number of keys that can be
+stored on an internal page by storing only as many bytes of each key as
+are necessary to distinguish it from adjacent keys.  The prefix comparison
+routine is what determines this minimum number of bytes (i.e., the length
+of the unique prefix), that must be stored.  A prefix comparison function
+for the Btree can be specified by calling <a href="../../api_c/db_set_bt_prefix.html">DB-&gt;set_bt_prefix</a>.
+<p>The prefix comparison routine must be compatible with the overall
+comparison function of the Btree, since what distinguishes any two keys
+depends entirely on the function used to compare them.  This means that
+if a prefix comparison routine is specified by the application, a
+compatible overall comparison routine must also have been specified.
+<p>Prefix comparison routines are passed pointers to keys as arguments.  The
+keys are represented as <a href="../../api_c/dbt.html">DBT</a> structures.  The prefix comparison
+function must return the number of bytes of the second key argument that
+are necessary to determine if it is greater than the first key argument.
+If the keys are equal, the length of the second key should be returned.
+The only fields that the routines may examine in the <a href="../../api_c/dbt.html">DBT</a>
+structures are <b>data</b> and <b>size</b> fields.
+<p>An example prefix comparison routine follows:
+<p><blockquote><pre>u_int32_t
+compare_prefix(dbp, a, b)
+	DB *dbp;
+	const DBT *a, *b;
+{
+	size_t cnt, len;
+	u_int8_t *p1, *p2;
+<p>
+	cnt = 1;
+	len = a-&gt;size &gt; b-&gt;size ? b-&gt;size : a-&gt;size;
+	for (p1 =
+		a-&gt;data, p2 = b-&gt;data; len--; ++p1, ++p2, ++cnt)
+			if (*p1 != *p2)
+				return (cnt);
+	/*
+	 * They match up to the smaller of the two sizes.
+	 * Collate the longer after the shorter.
+	 */
+	if (a-&gt;size &lt; b-&gt;size)
+		return (a-&gt;size + 1);
+	if (b-&gt;size &lt; a-&gt;size)
+		return (b-&gt;size + 1);
+	return (b-&gt;size);
+}</pre></blockquote>
+<p>The usefulness of this functionality is data dependent, but in some data
+sets can produce significantly reduced tree sizes and faster search times.

+<h1 align=center>Selecting a cache size</h1>
+<p>The size of the cache used for the underlying database can be specified
+by calling the <a href="../../api_c/db_set_cachesize.html">DB-&gt;set_cachesize</a> function.
+Choosing a cache size is, unfortunately, an art.  Your cache must be at
+least large enough for your working set plus some overlap for unexpected
+situations.
+<p>When using the Btree access method, you must have a cache big enough for
+the minimum working set for a single access.  This will include a root
+page, one or more internal pages (depending on the depth of your tree),
+and a leaf page.  If your cache is any smaller than that, each new page
+will force out the least-recently-used page, and Berkeley DB will re-read the
+root page of the tree anew on each database request.
+<p>If your keys are of moderate size (a few tens of bytes) and your pages
+are on the order of 4K to 8K, most Btree applications
+will be only three levels.  For
+example, using 20 byte keys with 20 bytes of data associated with each
+key, a 8KB page can hold roughly 400 keys and 200 key/data pairs, so a
+fully populated three-level Btree will hold 32 million key/data pairs,
+and a tree with only a 50% page-fill factor will still hold 16 million
+key/data pairs.  We rarely expect trees to exceed five levels, although
+Berkeley DB will support trees up to 255 levels.
+<p>The rule-of-thumb is that cache is good, and more cache is better.
+Generally, applications benefit from increasing the cache size up to a
+point, at which the performance will stop improving as the cache size
+increases.  When this point is reached, one of two things have happened:
+either the cache is large enough that the application is almost never
+having to retrieve information from disk, or, your application is doing
+truly random accesses, and therefore increasing size of the cache doesn't
+significantly increase the odds of finding the next requested information
+in the cache.  The latter is fairly rare -- almost all applications show
+some form of locality of reference.
+<p>That said, it is important not to increase your cache size beyond the
+capabilities of your system, as that will result in reduced performance.
+Under many operating systems, tying down enough virtual memory will cause
+your memory and potentially your program to be swapped.  This is
+especially likely on systems without unified OS buffer caches and virtual
+memory spaces, as the buffer cache was allocated at boot time and so
+cannot be adjusted based on application requests for large amounts of
+virtual memory.
+<p>For example, even if accesses are truly random within a Btree, your
+access pattern will favor internal pages to leaf pages, so your cache
+should be large enough to hold all internal pages.  In the steady state,
+this requires at most one I/O per operation to retrieve the appropriate
+leaf page.
+<p>You can use the <a href="../../utility/db_stat.html">db_stat</a> utility to monitor the effectiveness of
+your cache.  The following output is excerpted from the output of that
+utility's <b>-m</b> option:
+<p><blockquote><pre>prompt: db_stat -m
+131072  Cache size (128K).
+4273    Requested pages found in the cache (97%).
+134     Requested pages not found in the cache.
+18      Pages created in the cache.
+116     Pages read into the cache.
+93      Pages written from the cache to the backing file.
+5       Clean pages forced from the cache.
+13      Dirty pages forced from the cache.
+0       Dirty buffers written by trickle-sync thread.
+130     Current clean buffer count.
+4       Current dirty buffer count.
+</pre></blockquote>
+<p>The statistics for this cache say that there have been 4,273 requests of
+the cache, and only 116 of those requests required an I/O from disk.  This
+means that the cache is working well, yielding a 97% cache hit rate.  The
+<a href="../../utility/db_stat.html">db_stat</a> utility will present these statistics both for the cache
+as a whole and for each file within the cache separately.

+<h1 align=center>Duplicate data items</h1>
+<p>The Btree and Hash access methods support the creation of multiple data
+items for a single key item.  By default, multiple data items are not
+permitted, and each database store operation will overwrite any previous
+data item for that key.  To configure Berkeley DB for duplicate data items, call
+the <a href="../../api_c/db_set_flags.html">DB-&gt;set_flags</a> function with the <a href="../../api_c/db_set_flags.html#DB_DUP">DB_DUP</a> flag.
+<p>By default, Berkeley DB stores duplicates in the order in which they were added,
+that is, each new duplicate data item will be stored after any already
+existing data items.  This default behavior can be overridden by using
+the <a href="../../api_c/dbc_put.html">DBcursor-&gt;c_put</a> function and one of the <a href="../../api_c/dbc_put.html#DB_AFTER">DB_AFTER</a>, <a href="../../api_c/dbc_put.html#DB_BEFORE">DB_BEFORE</a>
+<a href="../../api_c/dbc_put.html#DB_KEYFIRST">DB_KEYFIRST</a> or <a href="../../api_c/dbc_put.html#DB_KEYLAST">DB_KEYLAST</a> flags.  Alternatively, Berkeley DB
+may be configured to sort duplicate data items as described below.
+<p>When stepping through the database sequentially, duplicate data items will
+be returned individually, as a key/data pair, where the key item only
+changes after the last duplicate data item has been returned.  For this
+reason, duplicate data items cannot be accessed using the
+<a href="../../api_c/db_get.html">DB-&gt;get</a> function, as it always returns the first of the duplicate data
+items.  Duplicate data items should be retrieved using the Berkeley DB cursor
+interface, <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a>.
+<p>There is an interface flag that permits applications to request the
+following data item only if it <b>is</b> a duplicate data item of the
+current entry, see <a href="../../api_c/dbc_get.html#DB_NEXT_DUP">DB_NEXT_DUP</a> for more information.  There is an
+interface flag that permits applications to request the following data
+item only if it <b>is not</b> a duplicate data item of the current
+entry, see <a href="../../api_c/dbc_get.html#DB_NEXT_NODUP">DB_NEXT_NODUP</a> and <a href="../../api_c/dbc_get.html#DB_PREV_NODUP">DB_PREV_NODUP</a> for more
+information.
+<p>It is also possible to maintain duplicate records in sorted order.  Sorting
+duplicates will significantly increase performance when searching them
+and performing logical joins, common operations when creating secondary
+indexes.  To configure Berkeley DB to sort duplicate data items, the application
+must call the <a href="../../api_c/db_set_flags.html">DB-&gt;set_flags</a> function with the <a href="../../api_c/db_set_flags.html#DB_DUPSORT">DB_DUPSORT</a> flag (in
+addition to the <a href="../../api_c/db_set_flags.html#DB_DUP">DB_DUP</a> flag).  In addition, a custom sorting
+function may be specified using the <a href="../../api_c/db_set_dup_compare.html">DB-&gt;set_dup_compare</a> function.  If the
+<a href="../../api_c/db_set_flags.html#DB_DUPSORT">DB_DUPSORT</a> flag is given, but no comparison routine is specified,
+then Berkeley DB defaults to the same lexicographical sorting used for Btree
+keys, with shorter items collating before longer items.
+<p>If the duplicate data items are unsorted, applications may store identical
+duplicate data items, or, for those that just like the way it sounds,
+<i>duplicate duplicates</i>.
+<p><b>In this release it is an error to attempt to store identical
+duplicate data items when duplicates are being stored in a sorted order.</b>
+This restriction is expected to be lifted in a future release.  There is
+an interface flag that permits applications to disallow storing duplicate
+data items when the database has been configured for sorted duplicates,
+see <a href="../../api_c/db_put.html#DB_NODUPDATA">DB_NODUPDATA</a> for more information.  Applications not wanting
+to permit duplicate duplicates in databases configured for sorted
+duplicates should begin using the <a href="../../api_c/db_put.html#DB_NODUPDATA">DB_NODUPDATA</a> flag immediately.
+<p>For further information on how searching and insertion behaves in the
+presence of duplicates (sorted or not), see the <a href="../../api_c/db_get.html">DB-&gt;get</a>,
+<a href="../../api_c/db_put.html">DB-&gt;put</a>, <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a> and <a href="../../api_c/dbc_put.html">DBcursor-&gt;c_put</a> documentation.

+<h1 align=center>Selecting a Queue extent size</h1>
+<p>In Queue databases, records are allocated sequentially and directly
+mapped to an offset within the file storage for the database.  As
+records are deleted from the Queue, pages will become empty and will
+not be reused in normal queue operations.  To facilitate the reclamation
+of disk space a Queue may be partitioned into extents.  Each extent is
+kept in a separate physical file.  Extent files are automatically
+created as needed and destroyed when they are emptied of records.
+<p>The extent size specifies the number of pages that make up each extent.
+By default, if no extent size is specified, the Queue resides in a
+single file and disk space is not reclaimed.  In choosing an extent size
+there is a tradeoff between the amount of disk space used and the
+overhead of creating and deleting files.  If the extent size is too
+small, the system will pay a performance penalty, creating and deleting
+files frequently.  In addition, if the active part of the queue spans
+many files, all those files will need to be open at the same time,
+consuming system and process file resources.

+<h1 align=center>Specifying a database hash</h1>
+<p>The database hash determines in which bucket a particular key will reside.
+The goal of hashing keys is to distribute keys equally across the database

+the specified keys so that the resulting bucket usage is relatively
+uniform.  A hash function that does not work well can effectively turn
+into a sequential list.
+<p>No hash performs equally well on all possible data sets.  It is possible

+function can be checked using <a href="../../utility/db_stat.html">db_stat</a> utility.  By comparing the
+number of hash buckets and the number of keys, one can decide if the entries
+are hashing in a well-distributed manner.
+<p>The hash function for the hash table can be specified by calling the

+<p>
+<h1 align=center>What are the available access methods?</h1>
+<p>Berkeley DB currently offers four access methods: Btree, Hash, Queue and Recno.
+<h3>Btree</h3>
+<p>The Btree access method is an implementation of a sorted, balanced tree
+structure.  Searches, insertions, and deletions in the tree all take O(log
+base_b N) time, where base_b is the average number of keys per page, and
+N is the total number of keys stored.  Often, inserting ordered data into
+Btree implementations results in pages that are only half-full.  Berkeley DB
+makes ordered (or inverse ordered) insertion the best case, resulting in
+nearly full-page space utilization.
+<h3>Hash</h3>
+<p>The Hash access method data structure is an implementation of Extended
+Linear Hashing, as described in "Linear Hashing: A New Tool for File and
+Table Addressing", Witold Litwin, <i>Proceedings of the 6th
+International Conference on Very Large Databases (VLDB)</i>, 1980.
+<h3>Queue</h3>
+<p>The Queue access method stores fixed-length records with logical record
+numbers as keys.  It is designed for fast inserts at the tail and has a
+special cursor consume operation that deletes and returns a record from
+the head of the queue.  The Queue access method uses record level locking.
+<h3>Recno</h3>
+<p>The Recno access method stores both fixed and variable-length records with

+<h1 align=center>Logical record numbers</h1>
+<p>The Berkeley DB Btree, Queue and Recno access methods can operate on logical
+record numbers.  In all cases for the Queue and Recno access methods,
+and in some cases with the Btree access method, a record number is
+specified to reference a specific key/data pair.  In the case of Btree
+supporting duplicate data items, the logical record number refers to a
+key and all of its data items.
+<p>Record numbers are 32-bit unsigned types, which limits the number of
+logical records in a database to 4,294,967,296.  The first record in the
+database is record number 1.
+<p>Record numbers in Recno databases can be configured to run in either
+mutable or fixed mode: mutable, where logical record numbers change as
+records are deleted or inserted, and fixed, where record numbers never
+change regardless of the database operation.  Record numbers in Btree
+databases are always mutable, and as records are deleted or inserted, the
+logical record number for other records in the database can change.  See
+<a href="../../ref/am_conf/renumber.html">Logically renumbering records</a> for
+more information.
+<p>Record numbers in Queue databases are always fixed, and never change
+regardless of the database operation.
+<p>Configuring Btree databases to support record numbers can severely limit
+the throughput of applications with multiple concurrent threads writing
+the database, because locations used to store record counts often become
+hot spots that many different threads all need to update.

+<p>
+<h1 align=center>Selecting a page size</h1>
+<p>The size of the pages used in the underlying database can be specified by
+calling the <a href="../../api_c/db_set_pagesize.html">DB-&gt;set_pagesize</a> function.  The minimum page size is 512 bytes
+and the maximum page size is 64K bytes, and must be a power of two.  If
+no page size is specified by the application, a page size is selected
+based on the underlying filesystem I/O block size.  (A page size selected
+in this way has a lower limit of 512 bytes and an upper limit of 16K
+bytes.)
+<p>There are four issues to consider when selecting a pagesize: overflow
+record sizes, locking, I/O efficiency, and recoverability.
+<p>First, the page size implicitly sets the size of an overflow record.
+Overflow records are key or data items that are too large to fit on a
+normal database page because of their size, and are therefore stored in
+overflow pages.  Overflow pages are pages that exist outside of the normal
+database structure.  For this reason, there is often a significant
+performance penalty associated with retrieving or modifying overflow
+records.  Selecting a page size that is too small, and which forces the
+creation of large numbers of overflow pages, can seriously impact the
+performance of an application.
+<p>Second, in the Btree, Hash and Recno Access Methods, the finest-grained
+lock that Berkeley DB acquires is for a page.  (The Queue Access Method
+generally acquires record-level locks rather than page-level locks.)
+Selecting a page size that is too large, and which causes threads or
+processes to wait because other threads of control are accessing or
+modifying records on the same page, can impact the performance of your
+application.
+<p>Third, the page size specifies the granularity of I/O from the database
+to the operating system.  Berkeley DB will give a page-sized unit of bytes to
+the operating system to be scheduled for writing to the disk.  For many
+operating systems, there is an internal <b>block size</b> which is used
+as the granularity of I/O from the operating system to the disk.  If the
+page size is smaller than the block size, the operating system may be
+forced to read a block from the disk, copy the page into the buffer it
+read, and then write out the block to disk.  Obviously, it will be much
+more efficient for Berkeley DB to write filesystem-sized blocks to the operating
+system and for the operating system to write those same blocks to the
+disk.  Selecting a page size that is too small, and which causes the
+operating system to coalesce or otherwise manipulate Berkeley DB pages, can
+impact the performance of your application.  Alternatively, selecting a
+page size that is too large may cause Berkeley DB and the operating system to
+write more data than is strictly necessary.
+<p>Fourth, when using the Berkeley DB Transactional Data Store product, the page size may affect the errors
+from which your database can recover  See
+<a href="../../ref/transapp/reclimit.html">Berkeley DB Recoverability</a> for more
+information.

+<h1 align=center>Flat-text backing files</h1>
+<p>It is possible to back any Recno database (either fixed or variable
+length) with a flat-text source file.  This provides fast read (and
+potentially write) access to databases that are normally created and
+stored as flat-text files.  The backing source file may be specified by
+calling the <a href="../../api_c/db_set_re_source.html">DB-&gt;set_re_source</a> function.
+<p>The backing source file will be read to initialize the database.  In the
+case of variable length records, the records are assumed to be separated
+as described for the <a href="../../api_c/db_set_re_delim.html">DB-&gt;set_re_delim</a> function interface.  For example,
+standard UNIX byte stream files can be interpreted as a sequence of
+variable length records separated by ASCII newline characters.  This is
+the default.
+<p>When cached data would normally be written back to the underlying database
+file (e.g., <a href="../../api_c/db_close.html">DB-&gt;close</a> or <a href="../../api_c/db_sync.html">DB-&gt;sync</a> functions are called), the
+in-memory copy of the database will be written back to the backing source
+file.
+<p>The backing source file must already exist (but may be zero-length) when
+<a href="../../api_c/db_open.html">DB-&gt;open</a> is called.  By default, the backing source file is read
+lazily, i.e., records are not read from the backing source file until they
+are requested by the application. If multiple processes (not threads) are
+accessing a Recno database concurrently and either inserting or deleting
+records, the backing source file must be read in its entirety before more
+than a single process accesses the database, and only that process should
+specify the backing source file as part of the <a href="../../api_c/db_open.html">DB-&gt;open</a> call.
+This can be accomplished by calling the <a href="../../api_c/db_set_flags.html">DB-&gt;set_flags</a> function with the
+<a href="../../api_c/db_set_flags.html#DB_SNAPSHOT">DB_SNAPSHOT</a> flag.
+<p>Reading and writing the backing source file cannot be transactionally
+protected because it involves filesystem operations that are not part of
+the Berkeley DB transaction methodology. For this reason, if a temporary
+database is used to hold the records (a NULL was specified as the file
+argument to <a href="../../api_c/db_open.html">DB-&gt;open</a>), <b>it is possible to lose the
+contents of the backing source file if the system crashes at the right
+instant</b>. If a permanent file is used to hold the database (a file name
+was specified as the file argument to <a href="../../api_c/db_open.html">DB-&gt;open</a>), normal database
+recovery on that file can be used to prevent information loss.  It is
+still possible that the contents of the backing source file itself will
+be corrupted or lost if the system crashes.
+<p>For all of the above reasons, the backing source file is generally used
+to specify databases that are read-only for Berkeley DB applications, and that
+are either generated on the fly by software tools, or modified using a
+different mechanism such as a text editor.

+<p>
+<h1 align=center>Managing record-based databases</h1>
+<p>When using fixed- or variable-length record-based databases, particularly
+with flat-text backing files, there are several items that the user can
+control.  The Recno access method can be used to store either variable-
+or fixed-length data items.  By default, the Recno access method stores
+variable-length data items.  The Queue access method can only store
+fixed-length data items.
+<h3>Record Delimiters</h3>
+<p>When using the Recno access method to store variable-length records,
+records read from any backing source file are separated by a specific
+byte value which marks the end of one record and the beginning of the
+next.  This delimiting value is ignored except when reading records from
+a backing source file, that is, records may be stored into the database
+that include the delimiter byte.  However, if such records are written
+out to the backing source file and the backing source file is
+subsequently read into a database, the records will be split where
+delimiting bytes were found.
+<p>For example, UNIX text files can usually be interpreted as a sequence of
+variable-length records separated by ASCII newline characters.  This byte
+value (ASCII 0x0a) is the default delimiter.  Applications may specify a
+different delimiting byte using the <a href="../../api_c/db_set_re_delim.html">DB-&gt;set_re_delim</a> interface.
+If no backing source file is being used, there is no reason to set the
+delimiting byte value.
+<h3>Record Length</h3>
+<p>When using the Recno or Queue access methods to store fixed-length
+records, the record length must be specified.  Since the Queue access
+method always uses fixed-length records, the user must always set the
+record length prior to creating the database.  Setting the record length
+is what causes the Recno access method to store fixed-length, not
+variable-length, records.
+<p>The length of the records is specified by calling the
+<a href="../../api_c/db_set_re_len.html">DB-&gt;set_re_len</a> function.  The default length of the records is 0 bytes.
+Any record read from a backing source file or otherwise stored in the
+database that is shorter than the declared length will automatically be
+padded as described for the <a href="../../api_c/db_set_re_pad.html">DB-&gt;set_re_pad</a> function.  Any record stored
+that is longer than the declared length results in an error.  For
+further information on backing source files, see
+<a href="../../ref/am_conf/re_source.html">Flat-text backing files</a>.
+<h3>Record Padding Byte Value</h3>
+<p>When storing fixed-length records in a Queue or Recno database, a pad
+character may be specified by calling the <a href="../../api_c/db_set_re_pad.html">DB-&gt;set_re_pad</a> function.  Any
+record read from the backing source file or otherwise stored in the
+database that is shorter than the expected length will automatically be
+padded with this byte value.  If fixed-length records are specified but
+no pad value is specified, a space character (0x20 in the ASCII
+character set) will be used.  For further information on backing source
+files, see <a href="../../ref/am_conf/re_source.html">Flat-text backing
+files</a>.

+<p>
+<h1 align=center>Logically renumbering records</h1>
+<p>Records stored in the Queue and Recno access methods are accessed by
+logical record number.  In all cases in Btree databases, and optionally
+in Recno databases (see the <a href="../../api_c/db_set_flags.html">DB-&gt;set_flags</a> function and the
+<a href="../../api_c/db_set_flags.html#DB_RENUMBER">DB_RENUMBER</a> flag for more information), record numbers are
+mutable.  This means that the record numbers may change as records are
+added to and deleted from the database.  The deletion of record number
+4 causes any records numbered 5 and higher to be renumbered downward by
+1;  the addition of a new record after record number 4 causes any
+records numbered 5 and higher to be renumbered upward by 1.  In all
+cases in Queue databases, and by default in Recno databases, record
+numbers are not mutable, and the addition or deletion of records to the
+database will not cause already-existing record numbers to change.  For
+this reason, new records cannot be inserted between already-existing
+records in databases with immutable record numbers.
+<p>Cursors pointing into a Btree database or a Recno database with mutable
+record numbers maintain a reference to a specific record, rather than
+a record number, that is, the record they reference does not change as
+other records are added or deleted.  For example, if a database contains
+three records with the record numbers 1, 2, and 3, and the data items
+"A", "B", and "C", respectively, the deletion of record number 2 ("B")
+will cause the record "C" to be renumbered downward to record number 2.
+A cursor positioned at record number 3 ("C") will be adjusted and
+continue to point to "C" after the deletion.  Similarly, a cursor
+previously referencing the now deleted record number 2 will be
+positioned between the new record numbers 1 and 2, and an insertion
+using that cursor will appear between those records.   In this manner
+records can be added and deleted to a database without disrupting the
+sequential traversal of the database by a cursor.
+<p>Only cursors created using a single DB handle can adjust each
+other's position in this way, however.  If multiple DB handles
+have a renumbering Recno database open simultaneously (as when multiple
+processes share a single database environment), a record referred to by
+one cursor could change underfoot if a cursor created using another
+DB handle inserts or deletes records into the database.  For
+this reason, applications using Recno databases with mutable record
+numbers will usually make all accesses to the database using a single
+DB handle and cursors created from that handle, or will
+otherwise single-thread access to the database, e.g., by using the
+Berkeley DB Concurrent Data Store product.
+<p>In any Queue or Recno databases, creating new records will cause the
+creation of multiple records if the record number being created is more
+than one greater than the largest record currently in the database. For
+example, creating record number 28, when record 25 was previously the
+last record in the database, will implicitly create records 26 and 27
+as well as 28.  All first, last, next and previous cursor operations
+will automatically skip over these implicitly created records.  So, if
+record number 5 is the only record the application has created,
+implicitly creating records 1 through 4, the <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a> interface
+with the <a href="../../api_c/dbc_get.html#DB_FIRST">DB_FIRST</a> flag will return record number 5, not record
+number 1.  Attempts to explicitly retrieve implicitly created records
+by their record number will result in a special error return,
+<a href="../../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a>.
+<p>In any Berkeley DB database, attempting to retrieve a deleted record, using
+a cursor positioned on the record, results in a special error return,
+<a href="../../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a>.  In addition, when using Queue databases or Recno
+databases with immutable record numbers, attempting to retrieve a deleted

+<p>
+<h1 align=center>Selecting an access method</h1>
+<p>The Berkeley DB access method implementation unavoidably interacts with each
+application's data set, locking requirements and data access patterns.
+For this reason, one access method may result in dramatically better
+performance for an application than another one.  Applications whose data
+could be stored in more than one access method may want to benchmark their
+performance using the different candidates.
+<p>One of the strengths of Berkeley DB is that it provides multiple access methods
+with almost identical interfaces to the different access methods.  This
+means that it is simple to modify an application to use a different access
+method.  Applications can easily benchmark the different Berkeley DB access
+methods against each other for their particular data set and access pattern.
+<p>Most applications choose between using the Btree or Hash access methods
+or between using the Queue and Recno access methods, because each of the
+two pairs offer similar functionality.
+<h3>Hash or Btree?</h3>
+<p>The Hash and Btree access methods should be used when logical record
+numbers are not the primary key used for data access.  (If logical record
+numbers are a secondary key used for data access, the Btree access method
+is a possible choice, as it supports simultaneous access by a key and a
+record number.)
+<p>Keys in Btrees are stored in sorted order and the relationship between
+them is defined by that sort order.  For this reason, the Btree access
+method should be used when there is any locality of reference among keys.
+Locality of reference means that accessing one particular key in the
+Btree implies that the application is more likely to access keys near to
+the key being accessed, where "near" is defined by the sort order.  For
+example, if keys are timestamps, and it is likely that a request for an
+8AM timestamp will be followed by a request for a 9AM timestamp, the
+Btree access method is generally the right choice.  Or, for example, if
+the keys are names, and the application will want to review all entries
+with the same last name, the Btree access method is again a good choice.
+<p>There is little difference in performance between the Hash and Btree
+access methods on small data sets, where all, or most of, the data set
+fits into the cache.  However, when a data set is large enough that
+significant numbers of data pages no longer fit into the cache, then the
+Btree locality of reference described above becomes important for
+performance reasons.  For example, there is no locality of reference for
+the Hash access method, and so key "AAAAA" is as likely to be stored on
+the same data page with key "ZZZZZ" as with key "AAAAB".  In the Btree
+access method, because items are sorted, key "AAAAA" is far more likely
+to be near key "AAAAB" than key "ZZZZZ".  So, if the application exhibits
+locality of reference in its data requests, then the Btree page read into
+the cache to satisfy a request for key "AAAAA" is much more likely to be
+useful to satisfy subsequent requests from the application than the Hash
+page read into the cache to satisfy the same request.  This means that
+for applications with locality of reference, the cache is generally much
+"hotter" for the Btree access method than the Hash access method, and
+the Btree access method will make many fewer I/O calls.
+<p>However, when a data set becomes even larger, the Hash access method can
+outperform the Btree access method.  The reason for this is that Btrees
+contain more metadata pages than Hash databases.  The data set can grow
+so large that metadata pages begin to dominate the cache for the Btree
+access method.  If this happens, the Btree can be forced to do an I/O
+for each data request because the probability that any particular data
+page is already in the cache becomes quite small.  Because the Hash access
+method has fewer metadata pages, its cache stays "hotter" longer in the
+presence of large data sets.  In addition, once the data set is so large
+that both the Btree and Hash access methods are almost certainly doing
+an I/O for each random data request, the fact that Hash does not have to
+walk several internal pages as part of a key search becomes a performance
+advantage for the Hash access method as well.
+<p>Application data access patterns strongly affect all of these behaviors,
+for example, accessing the data by walking a cursor through the database
+will greatly mitigate the large data set behavior describe above because
+each I/O into the cache will satisfy a fairly large number of subsequent
+data requests.
+<p>In the absence of information on application data and data access
+patterns, for small data sets either the Btree or Hash access methods
+will suffice.  For data sets larger than the cache, we normally recommend
+using the Btree access method.  If you have truly large data, then the
+Hash access method may be a better choice.  The <a href="../../utility/db_stat.html">db_stat</a> utility
+is a useful tool for monitoring how well your cache is performing.
+<h3>Queue or Recno?</h3>
+<p>The Queue or Recno access methods should be used when logical record
+numbers are the primary key used for data access.  The advantage of the
+Queue access method is that it performs record level locking and for this
+reason supports significantly higher levels of concurrency than the Recno
+access method.  The advantage of the Recno access method is that it
+supports a number of additional features beyond those supported by the
+Queue access method, such as variable-length records and support for
+backing flat-text files.
+<p>Logical record numbers can be mutable or fixed: mutable, where logical
+record numbers can change as records are deleted or inserted, and fixed,
+where record numbers never change regardless of the database operation.
+It is possible to store and retrieve records based on logical record
+numbers in the Btree access method.  However, those record numbers are
+always mutable, and as records are deleted or inserted, the logical record
+number for other records in the database will change. The Queue access
+method always runs in fixed mode, and logical record numbers never change
+regardless of the database operation. The Recno access method can be
+configured to run in either mutable or fixed mode.
+<p>In addition, the Recno access method provides support for databases whose
+permanent storage is a flat text file and the database is used as a fast,
+temporary storage area while the data is being read or modified.

+<h1 align=center>Programmatic APIs</h1>
+<p>The Berkeley DB subsystems can be accessed through interfaces from multiple
+languages.  The standard library interface is ANSI C.  Applications can
+also use Berkeley DB via C++ or Java, as well as from scripting languages.
+Environments can be shared among applications written using any of theses
+APIs.  For example, you might have a local server written in C or C++, a
+script for an administrator written in Perl or Tcl, and a web based user
+interface written in Java, all sharing a single database environment.
+<h3>C</h3>
+<p>The Berkeley DB library is written entirely in ANSI C.  C applications use a
+single include file:
+<p><blockquote><pre>#include &lt;db.h&gt;</pre></blockquote>
+<h3>C++</h3>
+<p>The C++ classes provide a thin wrapper around the C API, with the major
+advantages being improved encapsulation and an optional exception
+mechanism for errors.  C++ applications use a single include file:
+<p><blockquote><pre>#include &lt;db_cxx.h&gt;</pre></blockquote>
+<p>The classes and methods are named in a fashion that directly corresponds
+to structures and functions in the C interface.  Likewise, arguments to
+methods appear in the same order as the C interface, except to remove the
+explicit <b>this</b> pointer.  The #defines used for flags are identical
+between the C and C++ interfaces.
+<p>As a rule, each C++ object has exactly one structure from the underlying
+C API associated with it.  The C structure is allocated with each
+constructor call and deallocated with each destructor call.  Thus, the
+rules the user needs to follow in allocating and deallocating structures
+are the same between the C and C++ interfaces.
+<p>To ensure portability to many platforms, both new and old, Berkeley DB makes as
+few assumptions as possible about the C++ compiler and library.  For
+example, it does not expect STL, templates or namespaces to be available.
+The newest C++ feature used is exceptions, which are used liberally to
+transmit error information.  Even the use of exceptions can be disabled
+at runtime.
+<h3>JAVA</h3>
+<p>The Java classes provide a layer around the C API that is almost identical
+to the C++ layer.  The classes and methods are, for the most part
+identical to the C++ layer.  Db constants and #defines are represented as
+"static final int" values.  Error conditions are communicated as Java
+exceptions.
+<p>As in C++, each Java object has exactly one structure from the underlying
+C API associated with it.  The Java structure is allocated with each
+constructor or open call, but is deallocated only by the Java garbage
+collector.  Because the timing of garbage collection is not predictable,
+applications should take care to do a close when finished with any object
+that has a close method.
+<h3>Dbm/Ndbm, Hsearch</h3>
+<p>Berkeley DB supports the standard UNIX interfaces <a href="../../api_c/dbm.html">dbm</a> (or its
+<a href="../../api_c/dbm.html">ndbm</a> variant) and <a href="../../api_c/hsearch.html">hsearch</a>.  After including a new header
+file and recompiling, <a href="../../api_c/dbm.html">dbm</a> programs will run orders of magnitude
+faster and their underlying databases can grow as large as necessary.
+Historic <a href="../../api_c/dbm.html">dbm</a> applications fail when some number of entries were
+inserted into the database, where the number depends on the effectiveness
+of the hashing function on the particular data set.

+<p>
+<h1 align=center>The big picture</h1>
+<p>The previous chapters in this Reference Guide have described applications
+that use the Berkeley DB Access Methods for fast data storage and retrieval.
+The applications we describe here and in subsequent chapters are similar
+in nature to the Access Method applications, but they are also fully
+recoverable in the face of application or system failure.
+<p>Application code that only uses the Berkeley DB Access Methods might appear as
+follows:
+<p><blockquote><pre>switch (ret = dbp-&gt;put(dbp, NULL, &key, &data, 0)) {
+case 0:
+	printf("db: %s: key stored.\n", (char *)key.data);
+	break;
+default:
+	dbp-&gt;err(dbp, ret, "dbp-&gt;put");
+	exit (1);
+}</pre></blockquote>
+<p>The underlying Berkeley DB architecture that supports this is:
+<p align=center><img src="smallpic.gif" alt="small">
+<p>As you can see from this diagram, the application makes calls into the
+Access Methods, and the Access Methods use the underlying shared memory
+buffer cache to hold recently used file pages in main memory.
+<p>When applications require recoverability, then their calls to the Access
+Methods must be wrapped in calls to the transaction subsystem.  The
+application must inform Berkeley DB where to begin and end transactions, and
+must be prepared for the possibility that an operation may fail at any
+particular time, causing the transaction to abort.
+<p>An example of transaction protected code might appear as follows:
+<p><blockquote><pre>retry:	if ((ret = txn_begin(dbenv, NULL, &tid)) != 0) {
+		dbenv-&gt;err(dbenv, ret, "txn_begin");
+		exit (1);
+	}
+<p>
+	switch (ret = dbp-&gt;put(dbp, tid, &key, &data, 0)) {
+	case DB_LOCK_DEADLOCK:
+		(void)txn_abort(tid);
+		goto retry;
+	case 0:
+		printf("db: %s: key stored.\n", (char *)key.data);
+		break;
+	default:
+		dbenv-&gt;err(dbenv, ret, "dbp-&gt;put");
+		exit (1);
+	}
+<p>
+	if ((ret = txn_commit(tid)) != 0) {
+		dbenv-&gt;err(dbenv, ret, "txn_commit");
+		exit (1);
+	}</pre></blockquote>
+<p>In this example, the same operation is being done as before, however, it
+is wrapped in transaction calls.  The transaction is started with
+<a href="../../api_c/txn_begin.html">txn_begin</a>, and finished with <a href="../../api_c/txn_commit.html">txn_commit</a>.  If the operation
+fails due to a deadlock, then the transaction is aborted using
+<a href="../../api_c/txn_abort.html">txn_abort</a>, after which the operation may be retried.
+<p>There are actually five major subsystems in Berkeley DB, as follows:
+<p><dl compact>
+<p><dt>The Access Methods<dd>The Access Method subsystem provides general-purpose support for creating
+and accessing database files formatted as Btrees, Hashed files, and
+Fixed- and Variable-length records.  These modules are useful in the
+absence of transactions for applications that need fast, formatted file
+support.  See <a href="../../api_c/db_open.html">DB-&gt;open</a> and <a href="../../api_c/db_cursor.html">DB-&gt;cursor</a> for more
+information.  These functions were already discussed in detail in the
+previous chapters.
+<p><dt>The Memory Pool<dd>The memory pool subsystem is the general-purpose shared memory buffer pool
+used by Berkeley DB.  This is the shared memory cache that allows multiple
+processes and threads within processes to share access to databases.  This
+module is useful outside of the Berkeley DB package for processes that require
+portable, page-oriented, cached, shared file access.
+<p><dt>Transactions<dd>The transaction subsystem allows a group of database changes to be
+treated as an atomic unit so that either all of the changes are done, or
+none of the changes are done.  The transaction subsystem implements the
+Berkeley DB transaction model.  This module is useful outside of the Berkeley DB
+package for processes that want to transaction protect their own data
+modifications.
+<p><dt>Locking<dd>The locking subsystem is the general-purpose lock manager used by Berkeley DB.
+This module is useful outside of the Berkeley DB package for processes that
+require a portable, fast, configurable lock manager.
+<p><dt>Logging<dd>The logging subsystem is the write-ahead logging used to support the Berkeley DB
+transaction model.  It is largely specific to the Berkeley DB package, and
+unlikely to be useful elsewhere except as a supporting module for the
+Berkeley DB transaction subsystem.
+</dl>
+<p>Here is a more complete picture of the Berkeley DB library:
+<p align=center><img src="bigpic.gif" alt="large">
+<p>In this example, the application makes calls to the Access Methods and to
+the transaction subsystem.  The Access Methods and transaction subsystem
+in turn make calls into the Buffer Pool, Locking and Logging subsystems
+on behalf of the application.
+<p>While the underlying subsystems can each be called independently.  For
+example, the Buffer Pool subsystem can be used apart from the rest of
+Berkeley DB by applications simply wanting a shared memory buffer pool, or
+the Locking subsystem may be called directly by applications that are
+doing their own locking outside of Berkeley DB.  However, this usage is fairly
+rare, and most applications will either use only the Access Methods, or
+the Access Methods wrapped in calls to the transaction interfaces.

+<h1 align=center>Programming model</h1>
+<p>The Berkeley DB distribution is a database library, where the library is linked
+into the address space of the code which uses it.  The code using Berkeley DB
+may be an application or it may be a server providing functionality to a
+number of clients via some form of inter-process or remote-process
+communication (IPC/RPC).
+<p>In the application model, one or more applications link the Berkeley DB library
+directly into their address spaces.  There may be many threads of control
+in this model, as Berkeley DB supports locking for both multiple processes and
+for multiple threads within a process.  This model provides significantly
+faster access to the database functionality, but implies trust among all
+threads of control sharing the database environment as they will have the
+ability to read, write and potentially corrupt each other's data.
+<p>In the client-server model, developers write a database server application
+that accepts requests via some form of IPC and issues calls to the Berkeley DB
+interfaces based on those requests.  In this model, the database server
+is the only application linking the Berkeley DB library into its address space.
+The client-server model trades performance for protection, as it does not
+require that the applications share a protection domain with the server,
+but IPC/RPC is slower than a function call.  Of course, in addition, this
+model greatly simplifies the creation of network client-server applications.

+<h1 align=center>Supporting utilities</h1>
+<p>There are several stand-alone utilities that provide supporting
+functionality for the Berkeley DB environment:
+<p><dl compact>
+<p><dt><a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a><dd>The <a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a> utility is the Berkeley DB RPC server, providing

+been configured for transactions.
+<p><dt><a href="../../utility/db_deadlock.html">db_deadlock</a><dd>The <a href="../../utility/db_deadlock.html">db_deadlock</a> utility runs as a daemon process, periodically
+traversing the database lock structures and aborting transactions when it
+detects a deadlock.  Generally, some form of deadlock detection must be
+done if a database environment has been configured for locking.
+<p><dt><a href="../../utility/db_dump.html">db_dump</a><dd>The <a href="../../utility/db_dump.html">db_dump</a> utility writes a copy of the database to a flat-text

+<p><dt><a href="../../utility/db_printlog.html">db_printlog</a><dd>The <a href="../../utility/db_printlog.html">db_printlog</a> utility displays the contents of Berkeley DB log files
+in a human-readable and parseable format.

+verifying the database format.
+</dl>
+<p>All of the functionality implemented for these utilities is also available
+as part of the standard Berkeley DB API.  This means that threaded applications
+can easily create a thread that calls the same Berkeley DB functions as do the
+utilities.  This often simplifies an application environment by removing
+the necessity for multiple processes to negotiate database and database
+environment creation and shutdown.

+<p>Special compile-time flags are required when compiling threaded
+applications on AIX.  If you are compiling a threaded application,
+you must compile with the _THREAD_SAFE flag and load with specific
+libraries, e.g., "-lc_r".  Specifying the compiler name with a
+trailing "_r" usually performs the right actions for the system.
+<p><blockquote><pre>xlc_r ...

+<p>AIX 4.1 only allows applications to map 10 system shared memory segments.
+In AIX 4.3 this has been raised to 256K segments, but only if you set the
+environment variable "export EXTSHM=ON".
+<hr size=1 noshade>
+<p><li><b>I can't create database files larger than 1GB on AIX.</b>
+<p>Berkeley DB does not include large-file support for AIX systems by default.
+Sleepycat Software has been told that the following changes will add
+large-file support on the AIX 4.2 and later releases, but we have not
+tested them ourselves.
+<p>Add the following lines to the <b>db_config.h</b> file in your build
+directory:
+<p><blockquote><pre>#ifdef	HAVE_FILE_OFFSET_BITS
+#define	_LARGE_FILES		/* AIX specific. */
+#endif</pre></blockquote>
+<p>Change the source code for <b>os/os_open.c</b> to always specify the
+<b>O_LARGEFILE</b> flag to the <b>open</b>(2) system call.
+<p>Recompile Berkeley DB from scratch.
+<p>Note that the documentation for the IBM Visual Age compiler states that
+it does not not support the 64-bit filesystem APIs necessary for creating
+large files, and that the ibmcxx product must be used instead.  We have
+not heard if the GNU gcc compiler supports the 64-bit APIs or not.
+<p>Finally, to create large files under AIX, the filesystem has to be
+configured to support large files and the system wide user hard-limit for
+file sizes has to be greater than 1GB.

+While only the Berkeley DB specific ones are described here, most of the
+standard GNU autoconf options are available and supported.  To see a

+These options are automatically enabled when Berkeley DB is compiled.  For this
+reason, binaries built on current versions of these systems may not run
+on earlier versions of the system, as the library and system calls

+symbolic link to javac in your PATH, because the configuration process
+uses the location of javac to determine the location of the Java include

+<h1 align=center>Changing compile or load options</h1>
+<p>You can specify compiler and/or compile and load time flags by using
+environment variables during Berkeley DB configuration.  For example, if you
+want to use a specific compiler, specify the CC environment variable
+before running configure:
+<p><blockquote><pre>prompt: env CC=gcc ../dist/configure</pre></blockquote>
+<p>Using anything other than the native compiler will almost certainly mean
+that you'll want to check the flags specified to the compiler and
+loader, too.
+<p>To specify debugging and optimization options for the C compiler,
+use the CFLAGS environment variable:
+<p><blockquote><pre>prompt: env CFLAGS=-O2 ../dist/configure</pre></blockquote>
+<p>To specify header file search directories and other miscellaneous options
+for the C preprocessor and compiler, use the CPPFLAGS environment variable:
+<p><blockquote><pre>prompt: env CPPFLAGS=-I/usr/contrib/include ../dist/configure</pre></blockquote>
+<p>To specify debugging and optimization options for the C++ compiler,
+use the CXXFLAGS environment variable:
+<p><blockquote><pre>prompt: env CXXFLAGS=-Woverloaded-virtual ../dist/configure</pre></blockquote>
+<p>To specify miscellaneous options or additional library directories for
+the linker, use the LDFLAGS environment variable:
+<p><blockquote><pre>prompt: env LDFLAGS="-N32 -L/usr/local/lib" ../dist/configure</pre></blockquote>
+<p>If you want to specify additional libraries, set the LIBS environment
+variable before running configure.  For example:
+<p><blockquote><pre>prompt: env LIBS="-lposix -lsocket" ../dist/configure</pre></blockquote>
+<p>would specify two additional libraries to load, "posix" and "socket".
+<p>Make sure that you prepend -L to any library directory names and that you
+prepend -I to any include file directory names!  Also, if the arguments
+you specify contain blank or tab characters, be sure to quote them as
+shown above, i.e. with single or double quotes around the values you're
+specifying for LIBS.
+<p>The env command is available on most systems, and simply sets one or more
+environment variables before running a command.  If the env command is
+not available to you, you can set the environment variables in your shell
+before running configure.  For example, in sh or ksh, you could do:
+<p><blockquote><pre>prompt: LIBS="-lposix -lsocket" ../dist/configure</pre></blockquote>
+<p>and in csh or tcsh, you could do:
+<p><blockquote><pre>prompt: setenv LIBS "-lposix -lsocket"
+prompt: ../dist/configure</pre></blockquote>
+<p>See your command shell's manual page for further information.

+<p>The <b>shmget</b>(2) interfaces are not always used on HP-UX, even

+<p>It is not possible to store the standard HP-UX msemaphore semaphores in

+your HP-UX release.)
+<hr size=1 noshade>
+<p><li><b>During configuration I see a message that large file support has
+been turned off.</b>
+<p>Some HP-UX system include files redefine "open" when big-file support (the
+HAVE_FILE_OFFSET_BITS and _FILE_OFFSET_BITS #defines) is enabled.  This
+causes problems when compiling for C++, where "open" is a legal
+identifier, used in the Berkeley DB C++ API.  For this reason, we automatically
+turn off big-file support when Berkeley DB is configured with a C++ API.  This
+should not be a problem for applications unless there is a need to create
+databases larger than 2GB.
+<hr size=1 noshade>
+<p><li><b>I can't compile and run multi-threaded applications.</b>
+<p>Special compile-time flags are required when compiling threaded
+applications on HP-UX.  If you are compiling a threaded application, you
+must compile with the _REENTRANT flag:
+<p><blockquote><pre>cc -D_REENTRANT ...</pre></blockquote>
+<p>The Berkeley DB library will automatically build with the correct options.
+<hr size=1 noshade>
+<p><li><b>An ENOMEM error is returned from <a href="../../api_c/env_open.html">DBENV-&gt;open</a> or
+<a href="../../api_c/env_remove.html">DBENV-&gt;remove</a>.</b>
+<p>Due to the constraints of the PA-RISC memory architecture, HP-UX does not
+allow a process to map a file into its address space multiple times.
+For this reason, each Berkeley DB environment may be opened only once by a
+process on HP-UX, i.e., calls to <a href="../../api_c/env_open.html">DBENV-&gt;open</a> will fail if the
+specified Berkeley DB environment has been opened and not subsequently closed.
+<hr size=1 noshade>
+<p><li><b>When compiling with gcc, I see the following error:
+<p><blockquote><pre>#error "Large Files (ILP32) not supported in strict ANSI mode."</pre></blockquote></b>
+<p>We believe this is an error in the HP-UX include files, but we don't
+really understand it.  The only workaround we have found is to add
+-D__STDC_EXT__ to the C preprocessor defines as part of compilation.
+<hr size=1 noshade>
+<p><li><b>When using the Tcl or Perl APIs (including running the test suite) I
+see the error "Can't shl_load() a library containing Thread Local Storage".</b>
+<p>This problem happens when HP-UX has been configured to use pthread mutex
+locking and an attempt is made to call Berkeley DB using the Tcl or Perl APIs.  We
+have never found any way to fix this problem as part of the Berkeley DB build
+process.  To work around the problem, rebuild tclsh or perl and modify its build
+process to explicitly link it against the HP-UX pthread library (currently
+/usr/lib/libpthread.a).
+<hr size=1 noshade>
+<p><li><b>When running an executable that has been dynamically linked 
+against the Berkeley DB library, I see the error "Can't find path for shared library" 
+even though I've correctly set the SHLIB_PATH environment variable.</b>
+<p>By default, some versions of HP-UX ignore the dynamic library search path
+specified by the SHLIB_PATH environment variable.  To work around this, specify
+the "+s" flag to ld when linking, or run
+<p><blockquote><pre>chatr +s enable -l /full/path/to/libdb-3.2.sl ...</pre></blockquote>
+<p>on the executable that is not working.

+<h1 align=center>Building for UNIX</h1>
+<p>The Berkeley DB distribution builds up to four separate libraries: the base C
+API Berkeley DB library and the optional C++, Java and Tcl API libraries.  For
+portability reasons each library is standalone and contains the full Berkeley DB
+support necessary to build applications, that is, the C++ API Berkeley DB
+library does not require any other Berkeley DB libraries to build and run C++
+applications.
+<p>The Berkeley DB distribution uses the Free Software Foundation's
+<a href="http://sourceware.cygnus.com/autoconf">autoconf</a> and
+<a href="http://www.gnu.org/software/libtool/libtool.html">libtool</a>
+tools to build on UNIX platforms.  In general, the standard configuration
+and installation options for these tools apply to the Berkeley DB distribution.
+<p>To perform the default UNIX build of Berkeley DB, first change to the
+<b>build_unix</b> directory, and then enter the following two commands:
+<p><blockquote><pre>../dist/configure
+make</pre></blockquote>
+<p>This will build the Berkeley DB library.
+<p>To install the Berkeley DB library, enter:
+<p><blockquote><pre>make install</pre></blockquote>
+<p>To rebuild Berkeley DB, enter:
+<p><blockquote><pre>make clean
+make</pre></blockquote>
+<p>If you change your mind about how Berkeley DB is to be configured, you must start
+from scratch by entering:
+<p><blockquote><pre>make realclean
+../dist/configure
+make</pre></blockquote>
+<p>To build multiple UNIX versions of Berkeley DB in the same source tree, create a
+new directory at the same level as the build_unix directory, and then
+configure and build in that directory:
+<p><blockquote><pre>mkdir build_bsdos3.0
+cd build_bsdos3.0
+../dist/configure
+make</pre></blockquote>
+<p>If you have trouble with any of these commands, please send email to the
+addresses found in the Sleepycat Software contact information.  In that
+email, please provide a complete copy of the commands that you entered
+and any output, along with a copy of any <b>config.log</b> or
+<b>config.cache</b> files created during configuration.

+<h1 align=center>Architecture independent FAQs</h1>
+<p><ol>
+<p><li><b>When compiling with gcc, I get unreferenced symbols, e.g.,:
+<p><blockquote><pre>symbol __muldi3: referenced symbol not found
+symbol __cmpdi2: referenced symbol not found</pre></blockquote></b>
+<p>On systems where they're available (e.g., HP-UX, Solaris), Berkeley DB uses
+64-bit integral types.  As far as we can tell, some versions of gcc
+don't support these types.  The simplest workaround is to reconfigure
+Berkeley DB using the --disable-bigfile configuration option, and then rebuild.
+<hr size=1 noshade>
+<p><li><b>My C++ program traps during a failure in a DB call on my
+gcc-based system.</b>
+<p>We believe there are some severe bugs in the implementation of exceptions
+for some gcc compilers.  Exceptions require some interaction between
+compiler, assembler, runtime libraries, and we're not sure exactly what
+is at fault, but one failing combination is gcc 2.7.2.3 running on SuSE
+Linux 6.0.  The problem on this system can be seen with a rather simple
+test case of an exception thrown from a shared library and caught in the
+main program.
+<p>A variation of this problem seems to occur on AIX, although we believe it
+does not necessarily involve shared libraries on that platform.
+<p>If you see a trap that occurs when an exception might be thrown by the DB
+runtime, we suggest that you use static libraries instead of dynamic
+(shared) libraries.  See the documentation for configuration.  If this
+doesn't work, and you have a choice of compilers, try using a more recent
+gcc or a non-gcc based compiler to build Berkeley DB.
+<p>Finally, you can disable the use of exceptions in the C++ runtime for
+Berkeley DB by using the <a href="../../api_c/db_create.html#DB_CXX_NO_EXCEPTIONS">DB_CXX_NO_EXCEPTIONS</a> flag with
+<a href="../../api_c/env_create.html">db_env_create</a> or <a href="../../api_c/db_create.html">db_create</a>.  When this flag is on, all
+C++ methods fail by returning an error code rather than throwing an
+exception.
+<hr size=1 noshade>
+<p><li><b>I get unexpected results and database corruption when running
+threaded programs.</b>
+<p><b>I get error messages that mutex (e.g., pthread_mutex_XXX or
+mutex_XXX) functions are undefined when linking applications with Berkeley DB.</b>
+<p>On some architectures, the Berkeley DB library uses the ISO POSIX standard
+pthreads and UNIX International (UI) threads interfaces for underlying
+mutex support, e.g., Solaris and HP-UX.  You can specify compilers,
+compiler flags or link with the appropriate thread library when loading
+your application, to resolve the undefined references:
+<p><blockquote><pre>cc ... -lpthread ...
+cc ... -lthread ...
+xlc_r ...
+cc ... -mt ...</pre></blockquote>
+<p>See the appropriate architecture-specific Reference Guide pages for more
+information.
+<p>On systems where more than one type of mutex is available, it may be
+necessary for applications to use the same threads package from which
+Berkeley DB draws its mutexes, e.g., if Berkeley DB was built to use the POSIX
+pthreads mutex calls for mutex support, the application may need to be
+written to use the POSIX pthreads interfaces for its threading model.
+While this is only conjecture at this time and we know of no systems that
+actually have this requirement, it's not unlikely that some exist.
+<p>In a few cases, Berkeley DB can be configured to use specific underlying mutex
+interfaces.  You can use the <a href="../../ref/build_unix/conf.html#--enable-posixmutexes">--enable-posixmutexes</a> and
+<a href="../../ref/build_unix/conf.html#--enable-uimutexes">--enable-uimutexes</a> configuration options to specify the POSIX and Unix
+International (UI) threads packages.  This should not, however, be
+necessary in most cases.
+<p>In some cases, it is vitally important to make sure that you load
+the correct library.  For example, on Solaris systems, there are POSIX
+pthread interfaces in the C library, and so applications can link Berkeley DB
+using only C library and not see any undefined symbols.  However, the C
+library POSIX pthread mutex support is insufficient for Berkeley DB and Berkeley DB
+cannot detect that fact.  Similar errors can arise when applications
+(e.g., tclsh) use dlopen to dynamically load Berkeley DB as a library.
+<p>If you are seeing problems in this area after you've confirmed that you're
+linking with the correct libraries, there are two other things you can
+try.  First, if your platform supports inter-library dependencies, we
+recommend that you change the Berkeley DB Makefile to specify the appropriate
+threads library when creating the Berkeley DB dynamic library, as an
+inter-library dependency.  Second, if your application is using dlopen to
+dynamically load Berkeley DB, specify the appropriate thread library on the link
+line when you load the application itself.

+<p><li><b>I get reports of uninitialized memory reads and writes when

+errors when running software analysis tools, build with the
+--enable-umrw configuration option.

+<p><li><b>Berkeley DB programs or the test suite fail unexpectedly.</b>
+<p>The Berkeley DB architecture does not support placing the shared memory regions
+on remote filesystems, e.g., the Network File System (NFS) or the Andrew
+File System (AFS).  For this reason, the shared memory regions (normally
+located in the database home directory) must reside on a local filesystem.
+See <a href="../../ref/env/region.html">Shared Memory Regions</a> for more
+information.
+<p>With respect to running the test suite, always check to make sure that

+<p>The <a href="../../utility/db_dump.html">db_dump185</a> utility is the utility that supports conversion
+of Berkeley DB 1.85 and earlier databases to current database formats.  If
+the errors look something like:
+<p><blockquote><pre>cc -o db_dump185 db_dump185.o
+ld:
+Unresolved:
+dbopen</pre></blockquote>
+<p>it means that the Berkeley DB 1.85 code was not found in the standard
+libraries.  To build <a href="../../utility/db_dump.html">db_dump185</a>, the Berkeley DB version 1.85 code
+must have already been built and installed on the system.  If the Berkeley DB
+1.85 header file is not found in a standard place, or the library is
+not part of the standard libraries used for loading, you will need to
+edit your Makefile, and change the lines:
+<p><blockquote><pre>DB185INC=
+DB185LIB=</pre></blockquote>
+<p>So that the system Berkeley DB 1.85 header file and library are found, e.g.,

+<h1 align=center>QNX</h1>
+<p><ol>
+<p><li><b>To what versions of QNX has DB been ported?</b>
+<p>Berkeley DB has been ported to the QNX Neutrino technology which is commonly
+referred to as QNX RTP (Real-Time Platform).  Berkeley DB has not been
+ported to earlier versions of QNX, such as QNX 4.25.
+<p><li><b>What is the impact of QNX's use of <b>shm_open</b>(2) for
+shared memory regions?</b>
+<p>QNX requires the use of the POSIX <b>shm_open</b>(2) and
+<b>shm_unlink</b>(2) calls for shared memory regions that will later
+be mapped into memory using <b>mmap</b>(2).  QNX's implementation
+of the shared memory functions requires that the name given must begin
+with a slash, and that no other slash may appear in the name.
+<p>In order to comply with those requirements and allow relative pathnames
+to find the same environment, Berkeley DB uses only the last component of the
+home directory path and the name of the shared memory file, separated
+by a colon, as the name specified to the shared memory functions.  For
+example, if an application specifies a home directory of
+<b>/home/db/DB_DIR</b>, Berkeley DB will use <b>/DB_DIR:__db.001</b> as
+the name for the shared memory area argument to <b>shm_open</b>(2).
+<p>The impact of this decision is that the last component of all
+environment home directory pathnames on QNX must be unique with respect
+to each other.  Additionally, Berkeley DB requires that environments use home
+directories for QNX in order to generate a reasonable entry in the
+shared memory area.
+<p><li><b>What are the implications of QNX's requirement to use
+<b>shm_open</b>(2) in order to use <b>mmap</b>(2)?</b>
+<p>QNX requires that files mapped with <b>mmap</b>(2) be opened using
+<b>shm_open</b>(2).  There are other places in addition to the
+environment shared memory regions, where Berkeley DB tries to memory map files
+if it can.
+<p>The memory pool subsystem normally attempts to use <b>mmap</b>(2)
+even when using private memory, as indicated by the <a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a>
+flag to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>.  In the case of QNX, if an application is
+using private memory, Berkeley DB will not attempt to map the memory and will
+instead use the local cache.

+<h1 align=center>Dynamic shared libraries</h1>
+<p><b>Warning</b>: the following information is intended to be generic and
+is likely to be correct for most UNIX systems.  Unfortunately, dynamic
+shared libraries are not standard between UNIX systems, so there may be
+information here that is not correct for your system.  If you have
+problems, consult your compiler and linker manual pages or your system
+administrator.
+<p>The Berkeley DB dynamic shared libraries are created with the name
+libdb-<b>major</b>.<b>minor</b>.so, where <b>major</b> is the major
+version number and <b>minor</b> is the minor version number.  Other
+shared libraries are created if Java and Tcl support are enabled,
+specifically libdb_java-<b>major</b>.<b>minor</b>.so and
+libdb_tcl-<b>major</b>.<b>minor</b>.so.
+<p>On most UNIX systems, when any shared library is created, the linker
+stamps it with a "SONAME".  In the case of Berkeley DB, the SONAME is
+libdb-<b>major</b>.<b>minor</b>.so.  It is important to realize that
+applications linked against a shared library remember the SONAMEs of the
+libraries they use and not the underlying names in the filesystem.
+<p>When the Berkeley DB shared library is installed, links are created in the
+install lib directory so that libdb-<b>major</b>.<b>minor</b>.so,
+libdb-<b>major</b>.so and libdb.so all reference the same library.  This
+library will have an SONAME of libdb-<b>major</b>.<b>minor</b>.so.
+<p>Any previous versions of the Berkeley DB libraries that are present in the
+install directory (such as libdb-2.7.so or libdb-2.so) are left unchanged.
+(Removing or moving old shared libraries is one drastic way to identify
+applications that have been linked against those vintage releases.)
+<p>Once you have installed the Berkeley DB libraries, unless they are installed in
+a directory where the linker normally looks for shared libraries, you will
+need to specify the installation directory as part of compiling and
+linking against Berkeley DB.  Consult your system manuals or system
+administrator for ways to specify a shared library directory when
+compiling and linking applications with the Berkeley DB libraries.  Many systems
+support environment variables (e.g., LD_LIBRARY_PATH, LD_RUN_PATH) ), or
+system configuration files (e.g., /etc/ld.so.conf) for this purpose.
+<p><b>Warning</b>: some UNIX installations may have an already existing
+<b>/usr/lib/libdb.so</b>, and this library may be an incompatible
+version of Berkeley DB.
+<p>We recommend that applications link against libdb.so (e.g., using -ldb).
+Even though the linker uses the file named libdb.so, the executable file
+for the application remembers the library's SONAME
+(libdb-<b>major</b>.<b>minor</b>.so).  This has the effect of marking
+the applications with the versions they need at link time.  Because
+applications locate their needed SONAMEs when they are executed, all
+previously linked applications will continue to run using the library they
+were linked with, even when a new version of Berkeley DB is installed and the
+file <b>libdb.so</b> is replaced with a new version.
+<p>Applications that know they are using features specific to a particular
+Berkeley DB release can be linked to that release.  For example, an application
+wanting to link to Berkeley DB major release "3" can link using -ldb-3, and
+applications that know about a particular minor release number can specify
+both major and minor release numbers, for example, -ldb-3.5.
+<p>If you want to link with Berkeley DB before performing library installation,
+the "make" command will have created a shared library object in the
+<b>.libs</b> subdirectory of the build directory, such as
+<b>build_unix/.libs/libdb-major.minor.so</b>.  If you want to link a
+file against this library, with, for example, a major number of "3" and
+a minor number of "5", you should be able to do something like:
+<p><blockquote><pre>cc -L BUILD_DIRECTORY/.libs -o testprog testprog.o -ldb-3.5
+env LD_LIBRARY_PATH="BUILD_DIRECTORY/.libs:$LD_LIBRARY_PATH" ./testprog</pre></blockquote>
+<p>where <b>BUILD_DIRECTORY</b> is the full directory path to the directory
+where you built Berkeley DB.
+<p>The libtool program (which is configured in the build_unix directory) can
+be used to set the shared library path and run a program.  For example,
+<p><blockquote><pre>libtool gdb db_dump</pre></blockquote>
+<p>runs the gdb debugger on the db_dump utility after setting the appropriate
+paths.  Libtool may not know what to do with arbitrary commands (it is
+hardwired to recognize "gdb" and some other commands).  If it complains
+the mode argument will usually resolve the problem:
+<p><blockquote><pre>libtool --mode=execute my_debugger db_dump</pre></blockquote>
+<p>On most systems, using libtool in this way is exactly equivalent to
+setting the LD_LIBRARY_PATH environment variable and then executing the
+program.  On other systems, using libtool has the virtue of knowing about
+any other details on systems that don't behave in this typical way.

+<p><li><b>I can't compile and run multi-threaded applications.</b>
+<p>Special compile-time flags and additional libraries are required when
+compiling threaded applications on Solaris.  If you are compiling a
+threaded application, you must compile with the D_REENTRANT flag and link
+with the libpthread.a or libthread.a libraries:
+<p><blockquote><pre>cc -mt ...
+cc -D_REENTRANT ... -lthread
+cc -D_REENTRANT ... -lpthread</pre></blockquote>
+<p>The Berkeley DB library will automatically build with the correct options.

+<p><li><b>I've installed gcc on my Solaris system, but configuration

+<p>On some versions of Solaris, there is a cc executable in the user's path,

+<p><blockquote><pre>% which cc
+/usr/ucb/cc
+% cc
+/usr/ucb/cc: language optional software package not installed</pre></blockquote>
+<p>As Berkeley DB always uses the native compiler in preference to gcc, this is a
+fatal error.  If the error message you're seeing is:
+<p><blockquote><pre>checking whether the C compiler (cc -O ) works... no
+configure: error: installation or configuration problem: C compiler cannot create executables.</pre></blockquote>
+<p>then this may be the problem you're seeing.  The simplest workaround is
+to set your CC environment variable to the system compiler, e.g.:
+<p><blockquote><pre>env CC=gcc ../dist/configure</pre></blockquote>
+<p>and reconfigure.
+<p>If you are using the --configure-cxx option, you may also want to specify

+<p><li><b>I get error reports of non-existent files, corrupted metadata

+<p>Solaris 7 contains a bug in the threading libraries (-lpthread, -lthread)
+which causes the wrong version of the pwrite routine to be linked into
+the application if the thread library is linked in after the the C
+library.  The result will be that the pwrite function is called rather
+than the pwrite64.  To work around the problem, use an explicit link order
+when creating your application.
+<p>Sun Microsystems is tracking this problem with Bug Id's 4291109 and 4267207,
+and patch 106980-09 to Solaris 7 fixes the problem.
+<p><blockquote><pre>Bug Id: 4291109
+Duplicate of: 4267207
+Category: library
+Subcategory: libthread
+State: closed
+Synopsis: pwrite64 mapped to pwrite
+Description:
+When libthread is linked after libc, there is a table of functions in
+libthread that gets "wired into" libc via _libc_threads_interface().
+The table in libthread is wrong in both Solaris 7 and on28_35 for the
+TI_PWRITE64 row (see near the end).</pre></blockquote>
+<hr size=1 noshade>
+<p><li><b>During configuration I see a message that large file support has
+been turned off.</b>
+<p>The Solaris 8 system include files redefine "open" when big-file support (the
+HAVE_FILE_OFFSET_BITS and _FILE_OFFSET_BITS #defines) is enabled.  This
+causes problems when compiling for C++, where "open" is a legal
+identifier, used in the Berkeley DB C++ API.  For this reason, we automatically
+turn off big-file support when Berkeley DB is configured with a C++ API.  This
+should not be a problem for applications unless there is a need to create
+databases larger than 2GB.

+<h1 align=center>Running the test suite under UNIX</h1>
+<p>The Berkeley DB test suite is built if you specify --enable-test as an
+argument when configuring Berkeley DB.
+<p>Before running the tests for the first time, you may need to edit the
+<b>include.tcl</b> file in your build directory.  The Berkeley DB
+configuration assumes you intend to use the version of the tclsh utility
+included in the Tcl installation with which Berkeley DB was configured to run
+the test suite, and further assumes that the test suite will be run with
+the libraries pre-built in the Berkeley DB build directory.  If either of these
+assumptions are incorrect, you will need to edit the <b>include.tcl</b>
+file and change the line that reads:
+<p><blockquote><pre>set tclsh_path ...</pre></blockquote>
+<p>to correctly specify the full path to the version of tclsh with which you
+are going to run the test suite.  You may also need to change the line
+that reads:
+<p><blockquote><pre>set test_path ...</pre></blockquote>
+<p>to correctly specify the path from the directory where you are running
+the test suite to the location of the Berkeley DB Tcl API library you built.
+It may not be necessary that this be a full path if you have configured
+your system's dynamic shared library mechanisms to search the directory
+where you built or installed the Tcl library.
+<p>All Berkeley DB tests are run from within <b>tclsh</b>.  After starting tclsh,
+you must source the file <b>test.tcl</b> in the test directory.  For
+example, if you built in the <b>build_unix</b> directory of the
+distribution, this would be done using the command:
+<p><blockquote><pre>% source ../test/test.tcl</pre></blockquote>
+<p>Once you have executed that command and the "%" prompt has returned
+without errors, you are ready to run tests in the test suite.

+<p>
+<h1 align=center>VxWorks FAQ</h1>
+<p><ol>
+<p><li><b>Can I run the test suite under VxWorks?</b>
+<p>The test suite requires the Berkeley DB Tcl library.  In turn, this library
+requires Tcl 8.1 or greater.  In order to run the test suite, you would
+need to port Tcl 8.1 or greater to VxWorks.  The Tcl shell included in
+<i>windsh</i> is not adequate for two reasons.  First, it is based on
+Tcl 8.0.  Second, it does not include the necessary Tcl components for
+adding a Tcl extension.
+<p><li><b>Are all Berkeley DB features available for VxWorks?</b>
+<p>All Berkeley DB features are available for VxWorks with the exception of the
+<a href="../../api_c/db_open.html#DB_TRUNCATE">DB_TRUNCATE</a> flag for <a href="../../api_c/db_open.html">DB-&gt;open</a>.  The underlying mechanism
+needed for that flag is not available consistently across different file
+systems for VxWorks.
+<p><li><b>Are there any constraints using particular file system drivers?</b>
+<p>There are constraints using the dosFs file systems with Berkeley DB.  Namely,
+you must configure your dosFs file system to support long file names if
+you are using Berkeley DB logging in your application.  The VxWorks' dosFs
+1.0 file system, by default, uses the old MS-DOS 8.3 file naming
+constraints, restricting to 8 character file names with a 3 character
+extension.  If you have configured with VxWorks' dosFs 2.0 you should
+be compatible with Windows FAT32 filesystems which supports long
+filenames.
+<p><li><b>Are there any dependencies on particular file system drivers?</b>
+<p>There is one dependency on specifics of file system drivers in the port
+of Berkeley DB to VxWorks.  Berkeley DB synchronizes data using the FIOSYNC function
+to ioctl() (another option would have been to use the FIOFLUSH function
+instead).  The FIOSYNC function was chosen because the NFS client driver,
+nfsDrv, only supports it and doesn't support FIOFLUSH.  All local file
+systems, as of VxWorks 5.4, support FIOSYNC with the exception of
+rt11fsLib, which only supports FIOFLUSH.  To use rt11fsLib, you will need
+to modify the os/os_fsync.c file to use the FIOFLUSH function; note that
+rt11fsLib cannot work with NFS clients.
+<p><li><b>Are there any known file system problems?</b>
+<p>During the course of our internal testing we came across two problems
+with the dosFs 2.0 file system that warranted patches from Wind River Systems.
+You should ask Wind River Systems for the patches to these
+problems if you encounter them.
+<p>The first problem is that files will seem to disappear.  You should
+look at <b>SPR 31480</b> in the Wind River Systems' Support pages for
+a more detailed description of this problem.
+<p>The second problem is a semaphore deadlock within the dosFs file system
+code.  Looking at a stack trace via CrossWind, you will see two or more of
+your application's tasks waiting in semaphore code within dosFs.  The patch
+for this problem is under <b>SPR 33221</b> at Wind River Systems.
+<p><li><b>Are there any file systems I cannot use?</b>
+<p>The Target Server File System (TSFS) uses the netDrv driver.  This driver
+does not support any ioctl that allows flushing to the disk and therefore
+cannot be used with Berkeley DB.
+<p><li><b>Why aren't the utility programs part of the project?</b>
+<p>The utility programs, in their Unix-style form, are not ported to VxWorks.
+The reasoning is the utility programs are essentially wrappers for the
+specific Berkeley DB interface they call.  Their interface and generic model
+are not the appropriate paradigm for VxWorks.  It is most likely that
+specific applications will want to spawn tasks that call the appropriate
+Berkeley DB function to perform the actions of some utility programs, using
+VxWorks native functions.  For example, an application that spawns several
+tasks that all may operate on the same database would also want to spawn
+a task that calls <a href="../../api_c/lock_detect.html">lock_detect</a> for deadlock detection, but specific
+to the environment used for that application.
+<p><li><b>What VxWorks primitives are used for mutual exclusion in Berkeley DB?</b>
+<p>Mutexes inside of Berkeley DB use the basic binary semaphores in VxWorks.  The
+mutexes are created using the FIFO queue type.

+<p>Open the workspace <b>Berkeley DB.wsp</b>.  The list of projects
+in this workspace will be shown.  These projects were created for
+the x86 BSP for VxWorks.
+<p>The remainder of this document assumes you already have a
+VxWorks target and a target server, both up and running.
+<p>First, you'll need to set the include directories.
+To do this, go to the <i>Builds</i> tab for the workspace.
+Open up <i>Berkeley DB Builds</i>.  You will see several different
+builds, containing different configurations.  All of the projects
+in the Berkeley DB workspace are created to be downloadable applications.
+<p><table border=1 align=center>
+<tr><th>Build</th><th>Description</th></tr>

+</table>
+<p>You will have to add a new build specification if you are using a
+different BSP or wish to customize further.  For instance, if you have
+the Power PC (PPC) BSP, you will need to add a new build for the PPC tool
+chain.  To do so, select the "Builds" tab and then select the Berkeley DB
+project name and right click.  Choose the <i>New Build...</i>
+selection and create the new build target.  For your new build target,
+you will need to decide if you want it configured to support RPC and
+whether it should be built for debugging.  See the properties of the
+Pentium builds for how to configure for each case.  After you have added
+this build you still need to correctly configure the include directories
+as described below.
+<p>Select the build you are interested in and right click.  Choose the
+<i>Properties...</i> selection.  At this point, a tabbed dialogue
+should appear.  In this new window, choose the <i>C/C++ compiler</i>
+tab.  In the edit box, you need to modify the full pathname of the
+<i>build_vxworks</i> subdirectory of Berkeley DB, followed by the full
+pathname of the <i>include</i> subdirectory of Berkeley DB.  Then click
+OK.
+<p>If the architecture for this new build has the most significant byte
+first, you will also need to edit the <i>db_config.h</i> file in
+the build directory and define <b>WORDS_BIGENDIAN</b>.
+<p>To build and download the Berkeley DB downloadable application for the first time
+requires several steps: 
+<p><ol>
+<p><li>Select the build you are interested in and right click.
+Choose the <i>Set ... as Active Build</i> selection.
+<p><li>Select the build you are interested in and right click.
+Choose the <i>Dependencies ...</i> selection.
+Run dependencies over all files in the Berkeley DB project.
+<p><li>Select the build you are interested in and right click.
+Choose the <i>Rebuild All (Berkeley DB.out)</i> selection.
+<p><li>Select the Berkeley DB project name and right click.
+Choose the <i>Download 'Berkeley DB.out'</i> selection.
+</ol>
+<p>You will need to repeat this procedure for
+all builds you are interested in building, as well as for
+all of the example project builds you wish to run.

+<h1 align=center>VxWorks notes</h1>
+<p>Berkeley DB currently disallows the DB_TRUNC flag to <a href="../../api_c/db_open.html">DB-&gt;open</a>.
+The operations this flag represent are not fully supported under
+VxWorks 5.4.
+<p>The memory on VxWorks is always resident and fully shared among all tasks
+running on the target.  For this reason, the <a href="../../api_c/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag
+is implied for any application that does not specify the
+<a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag.  Additionally, applications must use a
+segment ID to ensure different applications do not overwrite each other's
+database environments.
+See the <a href="../../api_c/env_set_shm_key.html">DBENV-&gt;set_shm_key</a> function for more information.
+Also, the <a href="../../api_c/env_open.html#DB_LOCKDOWN">DB_LOCKDOWN</a> flag has no effect.
+<p>The <a href="../../api_c/db_sync.html">DB-&gt;sync</a> function is implemented using an ioctl call into the
+file system driver with the FIOSYNC command.  Most, but not all, file
+system drivers support this call.  Berkeley DB requires the use of a file system
+supporting FIOSYNC.
+<h3>Building and Running the Example Programs</h3>
+<p>Each example program can be downloaded and run by calling the function
+equivalent to the example's name.  You may have to edit the pathname to
+the environments and database names in the examples' sources.  The
+examples included are:
+<p><table border=1 align=center>

+<p><li><b>My Win* C/C++ application crashes in the Berkeley DB library when Berkeley DB calls
+fprintf (or some other standard C library function).</b>
+<p>You should be using the "Debug Multithreaded DLL" compiler option in
+your application when you link with the
+build_win32/Debug/libdb32d.lib library (this .lib file
+is actually a stub for libdb32d.DLL). To check this
+setting in Visual C++, choose the "Project/Settings" menu item, and
+under the tab marked "C/C++", select "Code Generation" and see the box
+marked "Use runtime library".  This should be set to "Debug
+Multithreaded DLL".  If your application is linked against the static
+library, build_win32/Debug/libdb32sd.lib, then you
+will want to set "Use runtime library" to "Debug Multithreaded".
+<p>Setting this option incorrectly can cause multiple versions of the
+standard libraries to be linked into your application (one on behalf
+of your application, and one on behalf of the Berkeley DB library).  That
+violates assumptions made by these libraries, and traps can result.
+<p><li><b>Why are the build options for DB_DLL marked as "Use MFC in a Shared DLL"?
+Does Berkeley DB use MFC?</b>
+<p>Berkeley DB does not use MFC at all.  It does however, call malloc and free and
+other facilities provided by the Microsoft C runtime library.  We've found
+in our work that many applications and libraries are built assuming MFC,
+and specifying this for Berkeley DB solves various interoperation issues, and
+guarantees that the right runtime libraries are selected.  Note that since
+we do not use MFC facilities, the MFC library DLL is not marked as a
+dependency for libdb.dll, but the appropriate Microsoft C runtime is.

+<h1 align=center>Building for Win32</h1>
+<p>The build_win32 directory in the Berkeley DB distribution contains project files
+for both MSVC 5.0 and 6.0:
+<p><table border=1 align=center>
+<tr><th>Project File</th><th>Description</th></tr>
+<tr>    <td align=center>Berkeley_DB.dsw</td>    <td align=center>Visual C++ 5.0 project (compatible with 6.0)</td>    </tr>
+<tr>    <td align=center>*.dsp</td>    <td align=center>Visual C++ 5.0 subprojects (compatible with 6.0
+)</td>    </tr>
+</table>
+<p>These project files can be used to build Berkeley DB for any Win32 platform:
+Windows 2000, Windows NT, Windows 98 and Windows 95.
+<h3>Building With Visual C++ 6.0</h3>
+<p>Open the file <b>Berkeley_DB.dsw</b>. You will be told that the project
+was generated by a previous version of Developer Studio, and asked if you
+want to convert the project. Select Yes, and all projects will be
+converted.  Then continue on with the instructions for building with
+Visual C++ 5.0.
+<p>Note that when you build a release version, you may receive a warning
+about an unknown compiler option <i>/Ob2</i>.  This is apparently a
+flaw in the project conversion for Visual C++ and can be ignored.
+<p>Each release of Berkeley DB is built and tested with this procedure using
+Microsoft Visual C++ 6.0, Standard Edition.
+<h3>Building With Visual C++ 5.0</h3>
+<p>Open the file <b>Berkeley_DB.dsw</b>.  This workspace includes a number
+of subprojects needed to build Berkeley DB.
+<p>First, you'll need to set the include directories.  To do this, select
+<i>Options...</i> from the <i>Tools</i> pull-down menu. At this
+point, a tabbed dialogue should appear.  In this new window, choose the
+<i>Directories</i> tab. For the <i>Platform</i>, select
+<i>Win32</i> and for <i>Show directories for</i> select
+<i>Include files</i>.  Below these options in the list of directories,
+you should add two directories: the full pathname of the
+<i>build_win32</i> subdirectory of Berkeley DB, followed by the full
+pathname of the <i>include</i> subdirectory of Berkeley DB. Then click OK.
+<p>Then, select <i>Active Project Configuration</i> under the
+<i>Build</i> pull-down menu.  For a debug version of the libraries,
+tools and examples, select <i>db_buildall - Win32 Debug</i>.
+Results from this build are put into <b>build_win32/Debug</b>.
+For a release version, select <i>db_buildall - Win32 Release</i>;
+results are put into <b>build_win32/Release</b>.
+For a debug version that has all tools and examples built with
+static libraries, select <i>db_buildall - Win32 Debug Static</i>;
+results are put into <b>build_win32/Debug_static</b>.
+For a release version of the same,
+select <i>db_buildall - Win32 Release Static</i>;
+results are put into <b>build_win32/Release_static</b>.
+Finally, to build, select <i>Build db_buildall.exe</i> under the
+<i>Build</i> pull-down menu.
+<p>When building your application, you should normally use compile options
+"debug multithreaded dll" and link against
+<b>build_win32/Debug/libdb32d.lib</b>.  If you want
+to link against a static (non-DLL) version of the library, use the
+"debug multithreaded" compile options and link against
+<b>build_win32/Debug_static/libdb32sd.lib</b>.  You can
+also build using a release version of the libraries and tools, which will be
+placed in <b>build_win32/Release/libdb32.lib</b>.
+The static version will be in
+<b>build_win32/Release_static/libdb32s.lib</b>.
+<p>Each release of Berkeley DB is maintained, built and tested using Microsoft
+Visual C++ 5.0 and 6.0.
+<h3>Including the C++ API</h3>
+<p>C++ support is built automatically on Win32.
+<h3>Including the Java API</h3>
+<p>Java support is not built automatically.  The following instructions
+assume you have installed the Sun Java Development Kit in
+<b>d:/java</b>.  Of course, if you've installed elsewhere, or have
+different Java software, you will need to adjust the pathnames
+accordingly.  First, use the instructions above for Visual C++ 5.0 or 6.0
+to open the Tools/Options tabbed dialog for adding include directories.
+In addition to the directories specified above, add
+<b>d:/java/include</b> and <b>d:/java/include/win32</b>.  These are
+the directories needed when including <b>jni.h</b>.  Now, before
+clicking OK, under <i>Show directories for</i>, choose
+<i>Executable files</i>.  Add <b>d:/java/bin</b>.  That directory
+is needed to find javac.  Now select OK.
+<p>Select <i>Active Project Configuration</i> under the
+<i>Build</i> pull-down menu.  Choose <i>db_java - Win32
+Release</i>. To build, select <i>Build
+libdb_java32.dll</i> under the <i>Build</i> pull-down
+menu.  This builds the Java support library for Berkeley DB and compiles all
+the java files, placing the class files in the <b>java/classes</b>
+subdirectory of Berkeley DB.  Set your environment variable CLASSPATH to
+include this directory, your environment variable PATH to include the
+<b>build_win32/Release</b> subdirectory, and as a test, try running
+the command:
+<p><blockquote><pre>java com.sleepycat.examples.AccessExample</pre></blockquote>
+<h3>Including the Tcl API</h3>
+<p>Tcl support is not built automatically.  See
+<a href="../../ref/tcl/intro.html">Loading Berkeley DB with Tcl</a> for information
+on sites from which you can download Tcl and which Tcl versions are
+compatible with Berkeley DB.
+<p>The Tcl library must be built as the same build type as the Berkeley DB
+library (both Release or both Debug).  We have found that the binary
+release of Tcl can be used with the Release configuration of Berkeley DB, but
+for the Debug configuration, you will need to need to build Tcl from
+sources.  Before building Tcl, you will need to modify its makefile to
+make sure you are building a debug version, including thread support.
+This is because the set of DLLs linked into the Tcl executable must
+match the corresponding set of DLLs used by Berkeley DB.
+<p>These notes assume Tcl is installed as <b>d:/tcl</b>, but you can
+change that if you wish.  If you run using a different version of Tcl
+than the one currently being used by Sleepycat Software, you will need
+to change the name of the Tcl library used in the build (e.g.,
+tcl83d.lib) to the appropriate name.  See
+Projects-&gt;Settings-&gt;Link in the db_tcl subproject.
+<p>Use the instructions above for
+Visual C++ 5.0 or 6.0 to open the <i>Tools/Options</i> tabbed dialog
+for adding include directories.  In addition to the directories specified
+above, add <b>d:/tcl/include</b>.  This is the directory that contains
+<b>tcl.h</b>.
+Then, in that same dialog, show directories for "Library Files".
+Add <b>d:/tcl/lib</b> (or whatever directory contains
+<b>tcl83d.lib</b> in your distribution) to the list.  Now select OK.
+<p>Select <i>Active Project Configuration</i> under the
+<i>Build</i> pull-down menu.  Choose <i>db_tcl - Win32
+Release</i>. To build, select <i>Build
+libdb_tcl32.dll</i> under the <i>Build</i> pull-down
+menu.  This builds the Tcl support library for Berkeley DB, placing the result
+into <b>build_win32/Release/libdb_tcl32.dll</b>.
+Selecting an Active Configuration of <i>db_tcl - Win32 Debug</i>
+will build a debug version, placing the result into
+<b>build_win32/Debug/libdb_tcl32d.dll</b>.

+<ul type=disc>
+<li>Various Berkeley DB interfaces take a <b>mode</b> argument, intended to specify
+the underlying file permissions for created files.  Berkeley DB currently ignores
+this argument on Windows systems.
+<p>It would be possible to construct a set of security attributes to pass to
+<b>CreateFile</b> that accurately represents the mode.  In the worst
+case, this would involve looking up user and all group names and creating
+an entry for each.  Alternatively, we could call the <b>_chmod</b>
+(partial emulation) function after file creation, although this leaves us
+with an obvious race.
+<p>Practically speaking, however, these efforts would be largely meaningless
+on FAT, the most common file system, which only has a "readable" and
+"writeable" flag, applying to all users.
+<li>When using the <a href="../../api_c/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag, Berkeley DB shared regions are
+created without ACLs, which means that the regions are only accessible
+to a single user.  If wider sharing is appropriate (e.g., both user
+applications and Windows/NT service applications need to access the
+Berkeley DB regions), the Berkeley DB code will need to be modified to create the
+shared regions with the correct ACLs.  Alternatively, by not specifying
+the <a href="../../api_c/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag, file-system backed regions will be
+created instead, and the permissions on those files may be directly
+specified through the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> interface.
+<li>On Windows/9X, files opened by multiple processes do not share data
+correctly.  For this reason, the <a href="../../api_c/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag is implied
+for any application that does not specify the <a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag,
+causing the system paging file to be used for sharing data.  However,
+paging file memory is freed on last close, implying that multiple
+processes sharing an environment must arrange for at least one process
+to always have the environment open, or, alternatively, that any process
+joining the environment be prepared to re-create it.  If a shared
+environment is closed by all processes, a subsequent open without
+specifying the <a href="../../api_c/env_open.html#DB_CREATE">DB_CREATE</a> flag will result in the return of a
+system EAGAIN error code.

+<h1 align=center>Running the test suite under Windows</h1>
+<p>To build the test suite on Win32 platforms you will need to configure
+Tcl support.  You will also need sufficient main memory and disk.
+Something around 100MB of disk will be sufficient.  For memory, 32MB is
+too small, we recommend at least 64MB.
+<h3>Building the software needed by the tests</h3>
+<p>There exist bugs in some versions of Tcl that may cause the test suite
+to hang on Windows/NT 4.0.  Tcl version 8.4 (currently available as an
+alpha release) has fixed the problem, or there are patches available
+for Tcl 8.3.2 (see bug #119188 in the Tcl SourceForge database).  Note
+that if you want to run the test suite against a Debug version of Berkeley DB,
+you need to build a debug version of Tcl.  This involves building Tcl
+from its source.
+<p>To build, perform the following steps.  Note that steps #1, #4 and #5
+are part of the normal build process for building Berkeley DB; #2, #3 are part
+of including the Tcl API.
+<p><ol>
+<p><li>Open the <b>build_win32/Berkeley_DB.dsw</b> workspace.
+<p><li>Add the pathname for the Tcl include subdirectory to your
+include path.  To do this, under the "Tools" menu item, select "Options".
+In the dialog, select the "Directories" tab, and choose directories
+for "Include Files".  Add <b>d:/tcl/include</b> (or whatever directory
+contains <b>tcl.h</b> in your distribution) to the list.
+<p><li>Add the pathname for the Tcl library subdirectory to your
+library path.  To do this, under the "Tools" menu item, select "Options".
+In the dialog, select the "Directories" tab, and choose directories for
+"Library Files".  Add <b>d:/tcl/lib</b> (or whatever directory contains
+<b>tcl83d.lib</b> in your distribution) to the list.
+<p><li>Set the active configuration to db_test -- Debug.  To set an
+active configuration, under the "Build" menu item in the IDE, select "Set
+Active Configuration".  Then choose "db_test -- Debug".
+<p><li>Build.  The IDE menu for this is called "build dbkill.exe",
+even though dbkill is just one of the things that is built.
+This step builds the base Berkeley DB .dll, tcl support,
+and various tools that are needed by the test suite.
+</ol>
+<h3>Running the test suite under Windows</h3>
+<p>Before running the tests for the first time, you must edit the file
+<b>include.tcl</b> in your build directory and change the line
+that reads:
+<p><blockquote><pre>set tclsh_path SET_YOUR_TCLSH_PATH</pre></blockquote>
+<p>You will want to use the location of the <b>tclsh</b> program.  For
+example, if Tcl is installed as <b>d:/tcl</b>, this line should be:
+<p><blockquote><pre>set tclsh_path d:/tcl/bin/tclsh83d.exe</pre></blockquote>
+<p>Then, in a shell of your choice enter the following commands:
+<p><ol>
+<p><li>cd build_win32
+<p><li>run <b>d:/tcl/bin/tclsh83d.exe</b>, or the equivalent name of
+the Tcl shell for your distribution.
+<p>You should get a "%" prompt.
+<p><li>% source ../test/test.tcl.
+<p>You should get a "%" prompt with no errors.
+</ol>
+<p>You are now ready to run tests in the test suite, see
+<a href="../../ref/test/run.html">Running the test suite</a> for more
+information.

+<p>
+<h1 align=center>Building Berkeley DB Concurrent Data Store applications</h1>
+<p>It is often desirable to have concurrent read-write access to a database
+when there is no need for full recoverability or transaction semantics.
+For this class of applications, Berkeley DB provides an interface supporting
+deadlock free, multiple-reader/single writer access to the database.
+This means that, at any instant in time, there may be either multiple
+readers accessing data or a single writer modifying data.  The
+application is entirely unaware of which is happening, and Berkeley DB
+implements the necessary locking and blocking to ensure this behavior.
+<p>In order to create Berkeley DB Concurrent Data Store applications, you must first initialize an
+environment by calling <a href="../../api_c/env_open.html">DBENV-&gt;open</a>.  You must specify the
+<a href="../../api_c/env_open.html#DB_INIT_CDB">DB_INIT_CDB</a> and <a href="../../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a> flags to that interface.
+It is an error to specify any of the other <a href="../../api_c/env_open.html">DBENV-&gt;open</a> subsystem
+or recovery configuration flags, e.g., <a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a>,
+<a href="../../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a> or <a href="../../api_c/env_open.html#DB_RECOVER">DB_RECOVER</a>.
+<p>All databases must, of course, be created in this environment, by using
+the <a href="../../api_c/db_create.html">db_create</a> interface and specifying the correct environment
+as an argument.
+<p>The Berkeley DB access method calls used to support concurrent access are
+unchanged from the normal access method calls, with one exception: the
+<a href="../../api_c/db_cursor.html">DB-&gt;cursor</a> interface.  In Berkeley DB Concurrent Data Store, each cursor must encapsulate
+the idea of being used for read-only access or for read-write access.
+There may only be one read-write cursor active at any one time.  When your
+application creates a cursor, if that cursor will ever be used for
+writing, the <a href="../../api_c/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a> flag must be specified when the cursor
+is created.
+<p>No deadlock detector needs to be run in a Berkeley DB Concurrent Data Store database environment.
+<p>Only a single thread of control may write the database at a time.  For
+this reason care must be taken to ensure that applications do not
+inadvertently block themselves causing the application to hang, unable
+to proceed.  Some common mistakes include:
+<p><ol>
+<p><li>Leaving a cursor open while issuing a <a href="../../api_c/db_put.html">DB-&gt;put</a> or <a href="../../api_c/db_del.html">DB-&gt;del</a>
+access method call.
+<p><li>Attempting to open a cursor for read-write access while already holding
+a cursor open for read-write access.
+<p><li>Not testing Berkeley DB error return codes (if any cursor operation returns an
+unexpected error, that cursor should be closed).
+<p><li>By default, Berkeley DB Concurrent Data Store does locking on a per-database basis.  For this reason,
+accessing multiple databases in different orders in different threads
+or processes, or leaving cursors open on one database while accessing
+another database, can cause an application to hang.  If this behavior
+is a requirement for the application, Berkeley DB can be configured to do
+locking on an environment wide basis.  See the <a href="../../api_c/env_set_flags.html#DB_CDB_ALLDB">DB_CDB_ALLDB</a> flag
+of the <a href="../../api_c/env_set_flags.html">DBENV-&gt;set_flags</a> function for more information.
+</ol>
+<p>Note that it is correct operation for two different threads of control
+(actual threads or processes) to have multiple read-write cursors open,
+or for one thread to issue a <a href="../../api_c/db_put.html">DB-&gt;put</a> call while another thread

+<h1 align=center>Common errors</h1>
+<p>This page outlines some of the most common problems that people encounter
+and some suggested courses of action.
+<p><dl compact>
+<p><dt><b>Symptom:</b><dd>Core dumps or garbage returns from random Berkeley DB operations.
+<p><dt>Possible Cause:<dd>Failure to zero out DBT structure before issuing request.
+<p><dt>Fix:<dd>Before using a <a href="../../api_c/dbt.html">DBT</a>, you must initialize all its elements
+to 0 and then set the ones you are using explicitly.
+<p><dt><b>Symptom:</b><dd>Random crashes and/or database corruption.
+<p><dt>Possible Cause:<dd>Running multiple threads, but did not specify <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a>
+to <a href="../../api_c/db_open.html">DB-&gt;open</a> or <a href="../../api_c/env_open.html">DBENV-&gt;open</a>.
+<p><dt>Fix:<dd>Any time you are sharing a handle across multiple threads, you must
+specify <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> when you open that handle.
+<p><dt><b>Symptom:</b><dd><a href="../../api_c/env_open.html">DBENV-&gt;open</a> returns EINVAL.
+<p><dt>Possible Cause:<dd>The environment home directory is a remote mounted filesystem.
+<p><dt>Fix:<dd>Use a locally mounted filesystem instead.
+<p><dt><b>Symptom:</b><dd><a href="../../api_c/db_get.html">DB-&gt;get</a> calls are returning EINVAL.
+<p><dt>Possible Cause:<dd>The application is running with threads, but did not specify the
+<a href="../../api_c/dbt.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a>, <a href="../../api_c/dbt.html#DB_DBT_REALLOC">DB_DBT_REALLOC</a> or <a href="../../api_c/dbt.html#DB_DBT_USERMEM">DB_DBT_USERMEM</a>
+flags in the <a href="../../api_c/dbt.html">DBT</a> structures used in the call.
+<p><dt>Fix:<dd>When running with threaded handles (i.e., specifying <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a>
+to <a href="../../api_c/env_open.html">DBENV-&gt;open</a> or <a href="../../api_c/db_open.html">DB-&gt;open</a>), you must specify one of those
+flags for all <a href="../../api_c/dbt.html">DBT</a> structures in which Berkeley DB is returning data.
+<p><dt><b>Symptom:</b><dd>Running multiple threads or processes, and the database appears to be
+getting corrupted.
+<p><dt>Possible Cause:<dd>Locking is not enabled.
+<p><dt>Fix:<dd>Make sure that you are acquiring locks in your access methods.  You
+must specify <a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a> to your <a href="../../api_c/env_open.html">DBENV-&gt;open</a> call and then
+pass that environment to <a href="../../api_c/db_open.html">DB-&gt;open</a>.
+<p><dt><b>Symptom:</b><dd>Locks are accumulating or threads and/or processes are
+deadlocking even though there is no concurrent access to the database.
+<p><dt>Possible Cause:<dd>Failure to close a cursor.
+<p><dt>Fix:<dd>Cursors retain locks between calls.  Everywhere the application uses
+a cursor, the cursor should be explicitly closed as soon as possible after
+it is used.
+<p><dt><b>Symptom:</b><dd>The system locks up.
+<p><dt>Possible Cause:<dd>Application not checking for <a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a>.
+<p><dt>Fix:<dd>Unless you are using the Concurrent Data Store product, whenever you
+have multiple threads and/or processes and at least one of them is
+writing, you have the potential for deadlock.  As a result, you must
+test for the <a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a> return on every Berkeley DB call.  In
+general, updates should take place in a transaction or you might leave
+the database in an inconsistent state.  Reads may take place outside
+the context of a transaction under common conditions.
+<p>Whenever you get a <a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a> return, you should:
+<p><ol>
+<p><li>If you are running in a transaction, abort the transaction, first closing
+any cursors opened in the transaction.
+<p><li>If you are not running in a transaction, simply close the cursor that got
+the <a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a> (if it was a cursor operation) and retry.
+</ol>
+<p>See <a href="../../ref/transapp/put.html">Recoverability and deadlock
+avoidance</a> for further information.
+<p><dt><b>Symptom:</b><dd>An inordinately high number of deadlocks.
+<p><dt>Possible Cause:<dd>Read-Modify-Write pattern without using the RMW flag.
+<p><dt>Fix:<dd>If you frequently read a piece of data, modify it and then write
+it, you may be inadvertently causing a large number of deadlocks.  Try
+specifying the <a href="../../api_c/dbc_get.html#DB_RMW">DB_RMW</a> flag on your get calls.
+<p>Or, if the application is doing a large number of updates in a small
+database, turning off Btree splits may help (see <a href="../../api_c/db_set_flags.html#DB_REVSPLITOFF">DB_REVSPLITOFF</a>
+for more information.)
+<p><dt><b>Symptom:</b><dd>I run recovery and it exits cleanly, but my database changes are missing.
+<p><dt>Possible Cause:<dd>Failure to enable logging and transactions in the database environment,
+failure to specify DB_ENV handle when creating DB handle,
+transaction handle not passed to Berkeley DB interface, failure to commit
+transaction.
+<p><dt>Fix:<dd>Make sure that the environment and database handles are properly
+created, and that the application passes the transaction handle returned
+by <a href="../../api_c/txn_begin.html">txn_begin</a> to the appropriate Berkeley DB interfaces, and that each
+transaction is eventually committed.
+<p><dt><b>Symptom:</b><dd>Recovery fails.
+<p><dt>Possible Cause:<dd>A database was updated in a transactional environment both with and
+without transactional handles.
+<p><dt>Fix:<dd>If any database write operation is done using a transaction handle,
+every write operation must be done in the context of a transaction.
+<p><dt><b>Symptom:</b><dd>A database environment locks up, sometimes gradually.
+<p><dt>Possible Cause:<dd>A thread of control exited unexpectedly, holding Berkeley DB resources.
+<p><dt>Fix:<dd>Whenever a thread of control exits holding Berkeley DB resources, all threads
+of control must exit the database environment, and recovery must be run.
+<p><dt><b>Symptom:</b><dd>A database environment locks up, sometimes gradually.
+<p><dt>Possible Cause:<dd>Cursors are not being closed before transaction abort.
+<p><dt>Fix:<dd>Before an application aborts a transaction, any cursors opened within
+the context of that transaction must be closed.
+<p><dt><b>Symptom:</b><dd>Transaction abort or recovery fail, or database corruption occurs.
+<p><dt>Possible Cause:<dd>Log files were removed before it was safe.
+<p><dt>Fix:<dd>Do not remove any log files from a database environment until Berkeley DB
+declares it safe.

+<h1 align=center>Introduction</h1>
+<p>As Berkeley DB is an embedded library, debugging applications that use Berkeley DB
+is both harder and easier than debugging a separate server.  Debugging
+can be harder, because, when a problem arises, it is not always readily
+apparent whether the problem is in the application, in the database
+library, or is a result of an unexpected interaction between the two.
+Debugging can be easier, as it is easier to track down a problem when
+you can review a stack trace rather than deciphering inter-process
+communication messages.  This chapter is intended to assist you in
+debugging applications and in reporting bugs to us in a manner such that
+we can provide you with the correct answer or fix as quickly as
+possible.
+<p>When you encounter a problem, there are a few general actions you can
+take:
+<p><dl compact>
+<p><dt>Review the Berkeley DB error output<dd>If an error output mechanism has been configured in the Berkeley DB
+environment, additional run-time error messages are made available to
+the applications.  If you are not using an environment, it is well worth
+modifying your application to create one so that you can get more
+detailed error messages.  See <a href="runtime.html">Run-time error
+information</a> for more information on configuring Berkeley DB to output these
+error messages.
+<p><dt>Review <a href="../../api_c/env_set_verbose.html">DBENV-&gt;set_verbose</a><dd>Check the list of flags for the <a href="../../api_c/env_set_verbose.html">DBENV-&gt;set_verbose</a> function, and
+see if any of them will produce additional information that might help
+understand the problem.
+<p><dt>Add run-time diagnostics<dd>You can configure and build Berkeley DB to perform run-time diagnostics.
+(These checks are not done by default as they can seriously impact
+performance.  See <a href="compile.html">Compile-time configuration</a> for more
+information.
+<p><dt>Apply all available patches<dd>Before reporting a problem to Sleepycat Software, please upgrade to the
+latest Sleepycat Software release of Berkeley DB, if possible, or at least
+make sure you have applied any updates available for your release from
+the <a href="http://www.sleepycat.com/update/index.html">Sleepycat
+Software web site</a>.
+<p><dt>Run the test suite<dd>If you are seeing repeated failures, or failures of simple test cases,
+run the Berkeley DB test suite to determine if the distribution of Berkeley DB you
+are using was built and configured correctly.

+<h1 align=center>Reviewing Berkeley DB log files</h1>
+<p>If you are running with transactions and logging, the <a href="../../utility/db_printlog.html">db_printlog</a>
+utility can be a useful debugging aid.  The <a href="../../utility/db_printlog.html">db_printlog</a> utility
+will display the contents of your log files in a human readable (and
+machine-processable) format.
+<p>The <a href="../../utility/db_printlog.html">db_printlog</a> utility will attempt to display any and all
+logfiles present in a designated db_home directory.  For each log record,
+<a href="../../utility/db_printlog.html">db_printlog</a> will display a line of the form:
+<p><blockquote><pre>[22][28]db_big: rec: 43 txnid 80000963 prevlsn [21][10483281]</pre></blockquote>
+<p>The opening numbers in square brackets are the log sequence number (LSN)
+of the log record being displayed.  The first number indicates the log
+file in which the record appears, and the second number indicates the
+offset in that file of the record.
+<p>The first character string identifies the particular log operation being
+reported.  The log records corresponding to particular operations are
+described below.  The rest of the line consists of name/value pairs.
+<p>The rec field indicates the record type (this is used to dispatch records
+in the log to appropriate recovery functions).
+<p>The txnid field identifies the transaction for which this record was
+written.  A txnid of 0 means that the record was written outside the
+context of any transaction.  You will see these most frequently for
+checkpoints.
+<p>Finally, the prevlsn contains the LSN of the last record for this
+transaction.  By following prevlsn fields, you can accumulate all the
+updates for a particular transaction.  During normal abort processing,
+this field is used to quickly access all the records for a particular
+transaction.
+<p>After the initial line identifying the record type, each field of the log
+record is displayed, one item per line.  There are several fields that
+appear in many different records and a few fields that appear only in
+some records.
+<p>The list below presents each log record type currently produced with a brief
+description of the operation they describe.

+<h3>Augmenting the Log for Debugging</h3>
+<p>When debugging applications, it is sometimes useful to log, not only the
+actual operations that modify pages, but also the underlying Berkeley DB
+functions being executed.  This form of logging can add significant bulk
+to your log, but can permit debugging application errors that are almost
+impossible to find any other way.  To turn on these log messages, specify
+the --enable-debug_rop and --enable-debug_wop configuration options when
+configuring Berkeley DB.  See <a href="../../ref/build_unix/conf.html">Configuring
+Berkeley DB</a> for more information.
+<h3>Extracting Committed Transactions and Transaction Status</h3>
+<p>Sometimes it is useful to use the human-readable log output to determine
+which transactions committed and aborted.  The awk script, commit.awk,
+found in the db_printlog directory of the Berkeley DB distribution allows you
+to do just that.  The command:
+<p><blockquote><pre>awk -f commit.awk log_output</pre></blockquote>
+where log_output is the output of db_printlog will display a list of
+the transaction IDs of all committed transactions found in the log.
+<p>If you need a complete list of both committed and aborted transactions,
+then the script status.awk will produce that.  The syntax is:
+<p><blockquote><pre>awk -f status.awk log_output</pre></blockquote>
+<h3>Extracting Transaction Histories</h3>
+<p>Another useful debugging aid is to print out the complete history of a
+transaction.  The awk script txn.awk, allows you to do that.  The
+command line:
+<p><blockquote><pre>awk -f txn.awk TXN=txnlist log_output</pre></blockquote>
+where log_output is the output of <a href="../../utility/db_printlog.html">db_printlog</a> and txnlist is
+a comma-separated list of transaction IDs, will display all log records
+associated with the designated transaction ids.
+<h3>Extracting File Histories</h3>
+<p>The awk script fileid.awk, allows you to extract all log records that
+affect particular files.  The syntax for the fileid.awk script is:
+<p><blockquote><pre>awk -f fileid.awk PGNO=fids log_output</pre></blockquote>
+<p>where log_output is the output of db_printlog and fids is a
+comma-separated list of fileids.  The script will output all log
+records that reference the designated file.
+<h3>Extracting Page Histories</h3>
+<p>The awk script pgno.awk, allows you to extract all log records that
+affect particular pages.  As currently designed, however, it will
+extract records of all files with the designated page number, so this
+script is most useful in conjunction with the fileid script.  The syntax
+for the pgno.awk script is:
+<p><blockquote><pre>awk -f pgno.awk PGNO=pgnolist log_output</pre></blockquote>
+<p>where log_output is the output of db_printlog and pgnolist is a
+comma-separated list of page numbers.  The script will output all log
+records that reference the designated page numbers.
+<h3>Other log processing tools</h3>
+<p>The awk script count.awk will print out the number of log records
+encountered that belonged to some transaction (that is the number of log
+records excluding those for checkpoints and non-transaction protected
+operations).
+<p>The script range.awk will extract a subset of a log.  This is useful
+when the output of <a href="../../utility/db_printlog.html">db_printlog</a> is too large to be reasonably
+manipulated with an editor or other tool.
+<p>The syntax for range.awk is:
+<p><blockquote><pre>awk -f range.awk START_FILE=sf START_OFFSET=so END_FILE=ef END_OFFSET=eo log_output</pre></blockquote>
+<p>where the <b>sf</b> and <b>so</b> represent the log sequence number
+(LSN) of the beginning of the sublog you wish to extract and <b>ef</b>
+and <b>eo</b> represent the LSN of the end of the sublog you wish to
+extract.

+<h1 align=center>Run-time error information</h1>
+<p>Normally, when an error occurs in the Berkeley DB library, an integer value
+(either a Berkeley DB specific value, or a system <b>errno</b> value) is
+returned by the function.  In some cases, however, this value may be
+insufficient to completely describe the cause of the error, especially
+during initial application debugging.
+<p>There are four interfaces intended to provide applications with
+additional run-time error information.  They are
+<a href="../../api_c/env_set_errcall.html">DBENV-&gt;set_errcall</a>, <a href="../../api_c/env_set_errfile.html">DBENV-&gt;set_errfile</a>,
+<a href="../../api_c/env_set_errpfx.html">DBENV-&gt;set_errpfx</a> and <a href="../../api_c/env_set_verbose.html">DBENV-&gt;set_verbose</a>.
+<p>If the environment is configured with these interfaces, many Berkeley DB errors
+will result in additional information being written to a file or passed
+as an argument to an application function.
+<p>The Berkeley DB error reporting facilities do not slow performance or
+significantly increase application size, and may be run during normal
+operation as well as during debugging.  Where possible, we recommend that
+these options always be configured and the output saved in the filesystem.
+We have found that that this often saves time when debugging installation
+or other system integration problems.
+<p>In addition, there are three routines to assist applications in
+displaying their own error messages: <a href="../../api_c/env_strerror.html">db_strerror</a>,
+<a href="../../api_c/db_err.html">DBENV-&gt;err</a> and <a href="../../api_c/db_err.html">DBENV-&gt;errx</a>.  The first is a superset of
+the ANSI C strerror interface, and returns a descriptive string for
+any error return from the Berkeley DB library.  The <a href="../../api_c/db_err.html">DBENV-&gt;err</a> and
+<a href="../../api_c/db_err.html">DBENV-&gt;errx</a> functions use the error message configuration options
+described above to format and display error messages to appropriate
+output devices.

+<h1 align=center>Dump output formats</h1>
+<p>There are two output formats used by <a href="../../utility/db_dump.html">db_dump</a> and <a href="../../utility/db_dump.html">db_dump185</a>.
+<p>In both output formats, the first few lines of the output contain header
+information describing the underlying access method, filesystem page size
+and other bookkeeping information.
+<p>The header information starts with a single line VERSION=N, where N is
+the version number of the dump output format.
+<p>The header information is then output in name=value pairs, where name may
+be any of the keywords listed in the <a href="../../utility/db_load.html">db_load</a> manual page, and
+value will be its value.  While this header information can be manually
+edited before the database is reloaded, there is rarely any reason to do
+so, as all of this information can also be specified or overridden by
+command-line arguments to <a href="../../utility/db_load.html">db_load</a>.
+<p>The header information ends with single line HEADER=END.
+<p>Following the header information are the key/data pairs from the database.
+If the database being dumped is of type Btree or Hash, or if the
+<b>-k</b> option as been specified, the output will be paired lines of
+text, where the first line of the pair is the key item, and the second
+line of the pair is its corresponding data item.  If the database being
+dumped is of type Queue or Recno and the <b>-k</b> has not been
+specified, the output will be lines of text, where each line is the next
+data item for the database.  Each of these lines will be preceded by a
+single space.
+<p>If the <b>-p</b> option to <a href="../../utility/db_dump.html">db_dump</a> or <a href="../../utility/db_dump.html">db_dump185</a> was
+specified, the key/data lines will consist of single characters
+representing any characters from the database that are <i>printing
+characters</i> and backslash (<b>\</b>) escaped characters
+for any that were not.  Backslash characters appearing in the output mean
+one of two things: if the backslash character precedes another backslash
+character, it means that a literal backslash character occurred in the
+key or data item.  If the backslash character precedes any other
+character, the next two characters must be interpreted as hexadecimal
+specification of a single character, e.g., <b>\0a</b> is
+a newline character in the ASCII character set.
+<p>Although some care should be exercised, it is perfectly reasonable to use
+standard text editors and tools to edit databases dumped using the
+<b>-p</b> option before re-loading them using the <a href="../../utility/db_load.html">db_load</a>
+utility.
+<p>Note that the definition of a printing character may vary from system to
+system, and so database representations created using the <b>-p</b>
+option may be less portable than those created without it.
+<p>If the <b>-p</b> option to <a href="../../utility/db_dump.html">db_dump</a> or <a href="../../utility/db_dump.html">db_dump185</a> is
+not specified, each output line will consist of paired hexadecimal values,
+e.g., the line <b>726f6f74</b> is the string <b>root</b> in the ASCII
+character set.
+<p>In all output formats, the key and data items are ended by a single line
+DATA=END.
+<p>Where multiple databases have been dumped from a file, the overall output
+will repeat, i.e., a new set of headers and a new set of data items.

+<h1 align=center>Creating an Environment</h1>
+<p>The <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function is the standard function for creating or
+joining a database environment.  Transaction-protected or multi-process
+applications should call <a href="../../api_c/env_open.html">DBENV-&gt;open</a> before making any other calls
+to the Berkeley DB library.  Applications must obtain an environment handle from
+the <a href="../../api_c/env_create.html">db_env_create</a> function before calling <a href="../../api_c/env_open.html">DBENV-&gt;open</a>.
+There are a large number of options that you can set to customize
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> for your environment.  These options fall into four
+broad categories:
+<p><dl compact>
+<p><dt>Subsystem Initialization:<dd>These flags indicate which Berkeley DB subsystems will be initialized for the
+environment, and, what operations will happen automatically when
+databases are accessed within the environment.  The flags include
+<a href="../../api_c/env_open.html#DB_JOINENV">DB_JOINENV</a>, <a href="../../api_c/env_open.html#DB_INIT_CDB">DB_INIT_CDB</a>, <a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a>,
+<a href="../../api_c/env_open.html#DB_INIT_LOG">DB_INIT_LOG</a>, <a href="../../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a> and <a href="../../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a>.
+The <a href="../../api_c/env_open.html#DB_INIT_CDB">DB_INIT_CDB</a> flag does initialization for Berkeley DB Concurrent Data Store
+applications, see <a href="../../ref/cam/intro.html">Building Berkeley DB Concurrent Data Store
+applications</a> for more information.  The rest of the flags initialize
+a single subsystem, e.g., when <a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a> is specified,
+applications reading and writing databases opened in this environment
+will be using locking to ensure that they do not overwrite each other's
+changes.
+<p><dt>Recovery options:<dd>These flags indicate what recovery is to be performed on the environment
+before it is opened for normal use, and include <a href="../../api_c/env_open.html#DB_RECOVER">DB_RECOVER</a> and
+<a href="../../api_c/env_open.html#DB_RECOVER_FATAL">DB_RECOVER_FATAL</a>.
+<p><dt>Naming options:<dd>These flags modify how file naming happens in the environment, and include
+<a href="../../api_c/env_open.html#DB_USE_ENVIRON">DB_USE_ENVIRON</a> and <a href="../../api_c/env_open.html#DB_USE_ENVIRON_ROOT">DB_USE_ENVIRON_ROOT</a>.
+<p><dt>Miscellaneous:<dd>Finally, there are a number of miscellaneous flags such as <a href="../../api_c/env_open.html#DB_CREATE">DB_CREATE</a>
+which causes underlying files to be created as necessary.  See the
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> manual pages for further information.
+</dl>
+<p>Most applications either specify only the <a href="../../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a> flag or
+they specify all four subsystem initialization flags
+(<a href="../../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a>, <a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a>, <a href="../../api_c/env_open.html#DB_INIT_LOG">DB_INIT_LOG</a> and
+<a href="../../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a>).  The former configuration is for applications that
+simply want to use the basic Access Method interfaces with a shared
+underlying buffer pool, but don't care about recoverability after
+application or system failure.  The latter is for applications that need
+recoverability.  There are situations where other combinations of the
+initialization flags make sense, but they are rare.
+<p>The <a href="../../api_c/env_open.html#DB_RECOVER">DB_RECOVER</a> flag is specified by applications that want to
+perform any necessary database recovery when they start running, i.e., if
+there was a system or application failure the last time they ran, they
+want the databases to be made consistent before they start running again.
+It is not an error to specify this flag when no recovery needs to be
+done.
+<p>The <a href="../../api_c/env_open.html#DB_RECOVER_FATAL">DB_RECOVER_FATAL</a> flag is more special-purpose.  It performs
+catastrophic database recovery, and normally requires that some initial
+arrangements be made, i.e., archived log files be brought back into the
+filesystem.  Applications should not normally specify this flag.  Instead,
+under these rare conditions, the <a href="../../utility/db_recover.html">db_recover</a> utility should be
+used.

+<h1 align=center>Error support</h1>
+<p>Berkeley DB offers programmatic support for displaying error return values.
+The <a href="../../api_c/env_strerror.html">db_strerror</a> interface returns a pointer to the error
+message corresponding to any Berkeley DB error return, similar to the ANSI C
+strerror interface, but able to handle both system error returns and
+Berkeley DB specific return values.
+<p>For example:
+<p><blockquote><pre>int ret;
+if ((ret = dbenv-&gt;set_cachesize(dbenv, 0, 32 * 1024)) != 0) {
+	fprintf(stderr, "set_cachesize failed: %s\n", db_strerror(ret));
+	return (1);
+}</pre></blockquote>
+<p>There are also two additional error functions, <a href="../../api_c/db_err.html">DBENV-&gt;err</a> and
+<a href="../../api_c/db_err.html">DBENV-&gt;errx</a>.  These functions work like the ANSI C printf
+interface, taking a printf-style format string and argument list, and
+writing a message constructed from the format string and arguments.
+<p>The <a href="../../api_c/db_err.html">DBENV-&gt;err</a> function appends the standard error string to the
+constructed message and the <a href="../../api_c/db_err.html">DBENV-&gt;errx</a> function does not.
+<p>Error messages can be configured always to include a prefix (e.g., the
+program name) using the <a href="../../api_c/env_set_errpfx.html">DBENV-&gt;set_errpfx</a> interface.
+<p>These functions provide simpler ways of displaying Berkeley DB error messages:
+<p><blockquote><pre>int ret;
+dbenv-&gt;set_errpfx(dbenv, argv0);
+if ((ret = dbenv-&gt;open(dbenv, home, NULL,
+    DB_CREATE | DB_INIT_LOG | DB_INIT_TXN | DB_USE_ENVIRON))
+    != 0) {
+	dbenv-&gt;err(dbenv, ret, "open: %s", home);
+	dbenv-&gt;errx(dbenv,
+	    "contact your system administrator: session ID was %d",
+	    session_id);
+	return (1);
+}</pre></blockquote>
+<p>For example, if the program was called "my_app", attempting to open an
+environment home directory in "/tmp/home", and the open call returned a
+permission error, the error messages shown would look like:
+<p><blockquote><pre>my_app: open: /tmp/home: Permission denied.
+my_app: contact your system administrator: session ID was 2</pre></blockquote>

+<h1 align=center>Introduction</h1>
+<p>A Berkeley DB environment is an encapsulation of one or more databases, log
+files and shared information about the database environment such as shared
+memory buffer cache pages.
+<p>The simplest way to administer a Berkeley DB application environment is to
+create a single <b>home</b> directory that stores the files for the
+applications that will share the environment.  The environment home
+directory must be created before any Berkeley DB applications are run.  Berkeley DB
+itself never creates the environment home directory.  The environment can
+then be identified by the name of that directory.
+<p>An environment may be shared by any number of applications as well as by
+any number of threads within the applications.  It is possible for an
+environment to include resources from other directories on the system,
+and applications often choose to distribute resources to other directories
+or disks for performance or other reasons.  However, by default, the
+databases, shared regions (the locking, logging, memory pool, and
+transaction shared memory areas) and log files will be stored in a single
+directory hierarchy.
+<p>It is important to realize that all applications sharing a database
+environment implicitly trust each other.  They have access to each other's
+data as it resides in the shared regions and they will share resources
+such as buffer space and locks.  At the same time, any applications using
+the same databases <b>must</b> share an environment if consistency is
+to be maintained between them.
+<p>The Berkeley DB environment is created and described by the <a href="../../api_c/env_create.html">db_env_create</a>
+and <a href="../../api_c/env_open.html">DBENV-&gt;open</a> interfaces.  In situations where customization is
+desired, such as storing log files on a separate disk drive, applications
+must describe the customization by either creating an environment
+configuration file in the environment home directory or by arguments
+passed to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> interface.  See the documentation on that
+function for details on this procedure.
+<p>Once an environment has been created, database files specified using
+relative pathnames will be named relative to the home directory.  Using
+pathnames relative to the home directory allows the entire environment
+to be easily moved to facilitate restoring and recovering a database in
+a different directory or on a different system.

+<p>
+<h1 align=center>File naming</h1>
+<p>The most important task of the environment is to structure file naming
+within Berkeley DB.
+<p>Each of the locking, logging, memory pool and transaction subsystems of
+Berkeley DB require shared memory regions, backed by the filesystem.  Further,
+cooperating applications (or multiple invocations of the same application)
+must agree on the location of the shared memory regions and other files
+used by the Berkeley DB subsystems, the log files used by the logging subsystem,
+and, of course, the data files.  Although it is possible to specify full
+pathnames to all Berkeley DB functions, this is cumbersome and requires
+that applications be recompiled when database files are moved.
+<p>Applications are normally expected to specify a single directory home for
+their database.  This can be done easily in the call to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>
+by specifying a value for the <b>db_home</b> argument.  There are more
+complex configurations where it may be desirable to override
+<b>db_home</b> or provide supplementary path information.
+<h3>Specifying file naming to Berkeley DB</h3>
+<p>The following describes the possible ways in which file naming information
+may be specified to the Berkeley DB library.  The specific circumstances and
+order in which these ways are applied are described in a subsequent
+paragraph.
+<p><dl compact>
+<p><dt><b><a name="db_home">db_home</a></b><dd>If the <b>db_home</b> argument to <a href="../../api_c/env_open.html">DBENV-&gt;open</a> is non-NULL, its
+value may be used as the database home, and files named relative to its
+path.
+<p><dt><a name="DB_HOME">DB_HOME</a><dd>If the DB_HOME environment variable is set when <a href="../../api_c/env_open.html">DBENV-&gt;open</a> is
+called, its value may be used as the database home, and files named
+relative to its path.
+<p>The DB_HOME environment variable is intended to permit users and system
+administrators to override application and installation defaults, e.g.:
+<p><blockquote><pre>env DB_HOME=/database/my_home application</pre></blockquote>
+<p>Application writers are encouraged to support the <b>-h</b> option
+found in the supporting Berkeley DB utilities to let users specify a database
+home.
+<p><dt>DB_ENV methods<dd>There are three DB_ENV methods that affect file naming.  The
+<a href="../../api_c/env_set_data_dir.html">DBENV-&gt;set_data_dir</a> function specifies a directory to search for database
+files.  The <a href="../../api_c/env_set_lg_dir.html">DBENV-&gt;set_lg_dir</a> function specifies a directory in which to
+create logging files.  The <a href="../../api_c/env_set_tmp_dir.html">DBENV-&gt;set_tmp_dir</a> function specifies a
+directory in which to create backing temporary files.  These methods are
+intended to permit applications to customize file location for a database.
+For example, an application writer can place data files and log files in
+different directories, or instantiate a new log directory each time the
+application runs.
+<p><dt><a name="DB_CONFIG">DB_CONFIG</a><dd>The same information specified to the above DB_ENV methods may also
+be specified using a configuration file.  If an environment home directory
+has been specified (either by the application specifying a non-NULL
+<b>db_home</b> argument to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>, or by the application
+setting the DB_USE_ENVIRON or DB_USE_ENVIRON_ROOT flags and the DB_HOME
+environment variable being set), any file named <b>DB_CONFIG</b> in the
+database home directory will be read for lines of the format <b>NAME
+VALUE</b>.
+<p>The characters delimiting the two parts of the entry may be one or more
+whitespace characters, and trailing whitespace characters are discarded.
+All empty lines or lines whose first character is a whitespace or hash
+(<b>#</b>) character will be ignored.  Each line must specify both
+the NAME and the VALUE of the pair.  The specific NAME VALUE pairs are
+documented in the manual <a href="../../api_c/env_set_data_dir.html">DBENV-&gt;set_data_dir</a>,
+<a href="../../api_c/env_set_lg_dir.html">DBENV-&gt;set_lg_dir</a> and <a href="../../api_c/env_set_tmp_dir.html">DBENV-&gt;set_tmp_dir</a> pages.
+<p>The DB_CONFIG configuration file is intended to permit systems to
+customize file location for an environment independent of applications
+using that database.  For example, a database administrator can move the
+database log and data files to a different location without application
+recompilation.
+</dl>
+<h3>File name resolution in Berkeley DB</h3>
+<p>The following describes the specific circumstances and order in which the
+different ways of specifying file naming information are applied.  Berkeley DB
+file name processing proceeds sequentially through the following steps:
+<p><dl compact>
+<p><dt>absolute pathnames<dd>If the file name specified to a Berkeley DB function is an absolute pathname,
+that file name is used without modification by Berkeley DB.
+<p>On UNIX systems, an absolute pathname is defined as any pathname that
+begins with a leading slash (<b>/</b>).
+<p>On Windows systems, an absolute pathname is any pathname that begins with
+a leading slash or leading backslash (<b>\</b>), or any
+pathname beginning with a single alphabetic character, a colon and a
+leading slash or backslash, e.g., <b>C:/tmp</b>.
+<p><dt>DB_ENV methods, DB_CONFIG<dd>If a relevant configuration string (e.g., set_data_dir), is specified
+either by calling a DB_ENV method or as a line in the DB_CONFIG
+configuration file, the VALUE from the <b>NAME VALUE</b> pair is
+prepended to the current file name.  If the resulting file name is an
+absolute pathname, the file name is used without further modification by
+Berkeley DB.
+<p><dt><b>db_home</b><dd>If the application specified a non-NULL <b>db_home</b> argument to
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> its value is prepended to the current file name.  If
+the resulting file name is an absolute pathname, the file name is used
+without further modification by Berkeley DB.
+<p><dt>DB_HOME<dd>If the <b>db_home</b> argument is null, the DB_HOME environment variable
+was set and the application has set the appropriate DB_USE_ENVIRON or
+DB_USE_ENVIRON_ROOT environment variable, its value is prepended to the
+current file name.  If the resulting file name is an absolute pathname,
+the file name is used without further modification by Berkeley DB.
+<p><dt>(nothing)<dd>Finally, all file names are interpreted relative to the current working
+directory of the process.
+</dl>
+<p>The common model for a Berkeley DB environment is one where only the DB_HOME
+environment variable, or the <b>db_home</b> argument, is specified.  In
+this case, all data file names are relative to that directory, and all
+files created by the Berkeley DB subsystems will be created in that directory.
+<p>The more complex model for a transaction environment might be one where
+a database home is specified, using either the DB_HOME environment
+variable or the <b>db_home</b> argument to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>, and then
+the data directory and logging directory are set to the relative path
+names of directories underneath the environment home.
+<h3>Examples</h3>
+Store all files in the directory <b>/a/database</b>:
+<p><blockquote><pre>DBENV-&gt;open(DBENV, "/a/database", ...);</pre></blockquote>
+Create temporary backing files in <b>/b/temporary</b>, and all other files
+in <b>/a/database</b>:
+<p><blockquote><pre>DBENV-&gt;set_tmp_dir(DBENV, "/b/temporary");
+DBENV-&gt;open(DBENV, "/a/database", ...);</pre></blockquote>
+Store data files in <b>/a/database/datadir</b>, log files in
+<b>/a/database/logdir</b>, and all other files in the directory
+<b>/a/database</b>:
+<p><blockquote><pre>DBENV-&gt;set_lg_dir("logdir");
+DBENV-&gt;set_data_dir("datadir");
+DBENV-&gt;open(DBENV, "/a/database", ...);</pre></blockquote>
+<p>Store data files in <b>/a/database/data1</b> and <b>/b/data2</b>, and
+all other files in the directory <b>/a/database</b>.  Any data files
+that are created will be created in <b>/b/data2</b>, because it is the
+first DB_DATA_DIR directory specified:
+<p><blockquote><pre>DBENV-&gt;set_data_dir(DBENV, "/b/data2");
+DBENV-&gt;set_data_dir(DBENV, "data1");
+DBENV-&gt;open(DBENV, "/a/database", ...);</pre></blockquote>

+<p>
+<h1 align=center>Shared Memory Regions</h1>
+<p>Each of the Berkeley DB subsystems within an environment is described by one or
+more regions.  The regions contain all of the per-process and per-thread
+shared information, including mutexes, that comprise a Berkeley DB environment.
+These regions are created in one of three areas, depending on the flags
+specified to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function:
+<p><ol>
+<p><li>If the <a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag is specified to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>, regions
+are created in per-process heap memory, i.e., memory returned by
+<b>malloc</b>(3).  In this case, the Berkeley DB environment may only be
+accessed by a single process, although that process may be
+multi-threaded.
+<p><li>If the <a href="../../api_c/env_open.html#DB_SYSTEM_MEM">DB_SYSTEM_MEM</a> flag is specified to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>,
+regions are created in system memory.  When regions are created in system
+memory, the Berkeley DB environment may be accessed by both multiple processes
+and multiple threads within processes.
+<p>The system memory used by Berkeley DB is potentially useful past the lifetime
+of any particular process.  Therefore, additional cleanup may be necessary
+after an application fails, as there may be no way for Berkeley DB to ensure
+that system resources backing the shared memory regions are returned to
+the system.
+<p>The system memory that is used is architecture-dependent.  For example,
+on systems supporting X/Open-style shared memory interfaces, e.g., UNIX
+systems, the <b>shmget</b>(2) and related System V IPC interfaces are
+used. Additionally, VxWorks systems use system memory.
+In these cases, an initial segment ID must be specified by the
+application to ensure that applications do not overwrite each other's
+database environments, and so that the number of segments created does
+not grow without bound.  See the <a href="../../api_c/env_set_shm_key.html">DBENV-&gt;set_shm_key</a> function for more
+information.
+<p><li>If no memory-related flags are specified to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>, then
+memory backed by the filesystem is used to store the regions.  On UNIX
+systems, the Berkeley DB library will use the POSIX mmap interface.  If mmap is
+not available, the UNIX shmget interfaces will be used, assuming they are

+<h1 align=center>Remote filesystems</h1>
+<p>When regions are backed by the filesystem, it is a common error to attempt
+to create Berkeley DB environments backed by remote file systems such as the
+Network File System (NFS) or the Andrew File System (AFS).  Remote
+filesystems rarely support mapping files into process memory, and even
+more rarely support correct semantics for mutexes after the attempt
+succeeds.  For this reason, we strongly recommend that the database
+environment directory reside in a local filesystem.
+<p>For remote file systems that do allow system files to be mapped into
+process memory, home directories accessed via remote file systems cannot
+be used simultaneously from multiple clients.  None of the commercial
+remote file systems available today implement coherent, distributed shared
+memory for remote-mounted files.  As a result, different machines will
+see different versions of these shared regions and the system behavior is
+undefined.
+<p>Databases, log files and temporary files may be placed on remote
+filesystems, <b>as long as the remote filesystem fully supports
+standard POSIX filesystem semantics</b>, although the application may incur
+a performance penalty for doing so.  Obviously, NFS-mounted databases
+cannot be accessed from more than one Berkeley DB environment (and therefore
+from more than one system), at a time since no Berkeley DB database may be
+accessed from more than one Berkeley DB environment at a time.
+<p><dl compact>
+<p><dt>Linux note:<dd>Some Linux releases are known to not support complete semantics for the
+POSIX fsync call on NFS-mounted filesystems.  No Berkeley DB files should be
+placed on NFS-mounted filesystems on these systems.

+<h1 align=center>Security</h1>
+<p>The following are security issues that should be considered when writing
+Berkeley DB applications:
+<p><dl compact>
+<p><dt>Database environment permissions<dd>The directory used as the Berkeley DB database environment should have its
+permissions set to ensure that files in the environment are not accessible
+to users without appropriate permissions.  Applications which add to the
+user's permissions (e.g., UNIX setuid or setgid applications), must be
+carefully checked to not permit illegal use of those permissions such
+as general file access in the environment directory.
+<p><dt>Environment variables<dd>Setting the <a href="../../api_c/env_open.html#DB_USE_ENVIRON">DB_USE_ENVIRON</a> and <a href="../../api_c/env_open.html#DB_USE_ENVIRON_ROOT">DB_USE_ENVIRON_ROOT</a> flags
+and allowing the use of environment variables during file naming can be
+dangerous.  Setting those flags in Berkeley DB applications with additional
+permissions (e.g., UNIX setuid or setgid applications) could potentially
+allow users to read and write databases to which they would not normally
+have access.
+<p><dt>File permissions<dd>By default, Berkeley DB always creates files readable and writeable by the owner
+and the group (i.e., S_IRUSR, S_IWUSR, S_IRGRP and S_IWGRP, or octal mode
+0660 on historic UNIX systems).  The group ownership of created files is
+based on the system and directory defaults, and is not further specified
+by Berkeley DB.
+<p><dt>Temporary backing files<dd>If an unnamed database is created and the cache is too small to hold the
+database in memory, Berkeley DB will create a temporary physical file to enable
+it to page the database to disk as needed.  In this case, environment
+variables such as <b>TMPDIR</b> may be used to specify the location of
+that temporary file.  While temporary backing files are created readable
+and writeable by the owner only (i.e., S_IRUSR and S_IWUSR, or octal mode
+0600 on historic UNIX systems), some filesystems may not sufficiently
+protect temporary files created in random directories from improper
+access.  Applications storing sensitive data in unnamed databases should
+use the <a href="../../api_c/env_set_tmp_dir.html">DBENV-&gt;set_tmp_dir</a> method to specify a temporary directory
+with known permissions, to be absolutely safe.

+<h1 align=center>An introduction to data management</h1>
+<p>Cheap, powerful computing and networking have created countless new
+applications that could not have existed a decade ago. The advent of
+the World-Wide Web, and its influence in driving the Internet into homes
+and businesses, is one obvious example. Equally important, though, is
+the  from large, general-purpose desktop and server computers
+toward smaller, special-purpose devices with built-in processing and
+communications services.
+<p>As computer hardware has spread into virtually every corner of our
+lives, of course, software has followed. Software developers today are
+building applications not just for conventional desktop and server
+environments, but also for handheld computers, home appliances,
+networking hardware, cars and trucks, factory floor automation systems,
+and more.
+<p>While these operating environments are diverse, the problems that
+software engineers must solve in them are often strikingly similar. Most
+systems must deal with the outside world, whether that means
+communicating with users or controlling machinery. As a result, most
+need some sort of I/O system. Even a simple, single-function system
+generally needs to handle multiple tasks, and so needs some kind of
+operating system to schedule and manage control threads. Also, many
+computer systems must store and retrieve data to track history, record
+configuration settings, or manage access.
+<p>Data management can be very simple. In some cases, just recording
+configuration in a flat text file is enough. More often, though,
+programs need to store and search a large amount of data, or
+structurally complex data. Database management systems are tools that
+programmers can use to do this work quickly and efficiently using
+off-the-shelf software.
+<p>Of course, database management systems have been around for a long time.
+Data storage is a problem dating back to the earliest days of computing.
+Software developers can choose from hundreds of good,
+commercially-available database systems. The problem is selecting the
+one that best solves the problems that their applications face.

+<h1 align=center>What is Berkeley DB?</h1>
+<p>So far, we've discussed database systems in general terms. It's time
+now to consider Berkeley DB in particular and see how it fits into the
+framework we have introduced. The key question is, what kinds of
+applications should use Berkeley DB?
+<p>Berkeley DB is an open source embedded database library that provides
+scalable, high-performance, transaction-protected data management
+services to applications.  Berkeley DB provides a simple function-call API
+for data access and management.
+<p>By "open source," we mean that Berkeley DB is distributed under a license that
+conforms to the <a href="http://www.opensource.org/osd.html">Open
+Source Definition</a>. This license guarantees that Berkeley DB is freely
+available for use and redistribution in other open source products.
+<a href="http://www.sleepycat.com">Sleepycat Software</a> sells
+commercial licenses for redistribution in proprietary applications, but
+in all cases the complete source code for Berkeley DB is freely available for
+download and use.
+<p>Berkeley DB is embedded because it links directly into the application.  It
+runs in the same address space as the application. As a result, no
+inter-process communication, either over the network or between
+processes on the same machine, is required for database operations.
+Berkeley DB provides a simple function-call API for a number of programming
+languages, including C, C++, Java, Perl, Tcl, Python, and PHP. All
+database operations happen inside the library. Multiple processes, or
+multiple threads in a single process, can all use the database at the
+same time as each uses the Berkeley DB library. Low-level services like
+locking, transaction logging, shared buffer management, memory
+management, and so on are all handled transparently by the library.
+<p>The library is extremely portable. It runs under almost all UNIX and
+Linux variants, Windows, and a number of embedded real-time operating
+systems. It runs on both 32-bit and 64-bit systems.
+It has been deployed on high-end
+Internet servers, desktop machines, and on palmtop computers, set-top
+boxes, in network switches, and elsewhere. Once Berkeley DB is linked into
+the application, the end user generally does not know that there's a
+database present at all.
+<p>Berkeley DB is scalable in a number of respects. The database library itself
+is quite compact (under 300 kilobytes of text space on common
+architectures), but it can manage databases up to 256 terabytes in size.
+It also supports high concurrency, with thousands of users operating on
+the same database at the same time. Berkeley DB is small enough to run in
+tightly constrained embedded systems, but can take advantage of
+gigabytes of memory and terabytes of disk on high-end server machines.
+<p>Berkeley DB generally outperforms relational and object-oriented database
+systems in embedded applications for a couple of reasons. First, because
+the library runs in the same address space, no inter-process
+communication is required for database operations. The cost of
+communicating between processes on a single machine, or among machines
+on a network, is much higher than the cost of making a function call.
+Second, because Berkeley DB uses a simple function-call interface for all
+operations, there is no query language to parse, and no execution plan
+to produce.
+<h3>Data Access Services</h3>
+<p>Berkeley DB applications can choose the storage structure that best suits the
+application. Berkeley DB supports hash tables, B-trees, simple
+record-number-based storage, and persistent queues. Programmers can
+create tables using any of these storage structures, and can mix
+operations on different kinds of tables in a single application.
+<p>Hash tables are generally good for very large databases that need
+predictable search and update times for random-access records.  Hash
+tables allow users to ask, "Does this key exist?" or to fetch a record
+with a known key.  Hash tables do not allow users to ask for records
+with keys that are close to a known key.
+<p>B-trees are better for range-based searches, as when the application
+needs to find all records with keys between some starting and ending
+value.  B-trees also do a better job of exploiting <i>locality
+of reference</i>.  If the application is likely to touch keys near each
+other at the same time, the B-trees work well. The tree structure keeps
+keys that are close together near one another in storage, so fetching
+nearby values usually doesn't require a disk access.
+<p>Record-number-based storage is natural for applications that need
+to store and fetch records, but that do not have a simple way to
+generate keys of their own. In a record number table, the record
+number is the key for the record. Berkeley DB will can generate these
+record numbers automatically.
+<p>Queues are well-suited for applications that create records, and then
+must deal with those records in creation order. A good example is
+on-line purchasing systems. Orders can enter the system at any time,
+but should generally be filled in the order in which they were placed.
+<h3>Data management services</h3>
+<p>Berkeley DB offers important data management services, including concurrency,
+transactions, and recovery. All of these services work on all of the
+storage structures.
+<p>Many users can work on the same database concurrently. Berkeley DB handles
+locking transparently, ensuring that two users working on the same
+record do not interfere with one another.
+<p>The library provides strict ACID transaction semantics. Some systems
+allow the user to relax, for example, the isolation guarantees that the
+database system makes. Berkeley DB ensures that all applications can see only
+committed updates.
+<p>Multiple operations can be grouped into a single transaction, and can
+be committed or rolled back atomically. Berkeley DB uses a technique called
+<i>two-phase locking</i> to be sure that concurrent transactions
+are isolated from one another, and a technique called
+<i>write-ahead logging</i> to guarantee that committed changes
+survive application, system, or hardware failures.
+<p>When an application starts up, it can ask Berkeley DB to run recovery.
+Recovery restores the database to a clean state, with all committed
+changes present, even after a crash. The database is guaranteed to be
+consistent and all committed changes are guaranteed to be present when
+recovery completes.
+<p>An application can specify, when it starts up, which data management
+services it will use. Some applications need fast,
+single-user, non-transactional B-tree data storage. In that case, the
+application can disable the locking and transaction systems, and will
+not incur the overhead of locking or logging. If an application needs
+to support multiple concurrent users, but doesn't need transactions, it
+can turn on locking without transactions. Applications that need
+concurrent, transaction-protected database access can enable all of the
+subsystems.
+<p>In all these cases, the application uses the same function-call API to
+fetch and update records.
+<h3>Design</h3>
+<p>Berkeley DB was designed to provide industrial-strength database services to
+application developers, without requiring them to become database
+experts.  It is a classic C-library style <i>toolkit</i>, providing
+a broad base of functionality to application writers.  Berkeley DB was designed
+by programmers, for programmers: its modular design surfaces simple,
+orthogonal interfaces to core services, and it provides mechanism (for
+example, good thread support) without imposing policy (for example, the
+use of threads is not required).  Just as importantly, Berkeley DB allows
+developers to balance performance against the need for crash recovery
+and concurrent use.  An application can use the storage structure that
+provides the fastest access to its data and can request only the degree
+of logging and locking that it needs.
+<p>Because of the tool-based approach and separate interfaces for each
+Berkeley DB subsystem, you can support a complete transaction environment for
+other system operations. Berkeley DB even allows you to wrap transactions
+around the standard UNIX file read and write operations!  Further, Berkeley DB
+was designed to interact correctly with the native system's toolset, a
+feature no other database package offers.  For example, Berkeley DB supports
+hot backups (database backups while the database is in use), using
+standard UNIX system utilities, e.g., dump, tar, cpio, pax or even cp.
+<p>Finally, because scripting language interfaces are available for Berkeley DB
+(notably Tcl and Perl), application writers can build incredibly powerful
+database engines with little effort.  You can build transaction-protected
+database applications using your favorite scripting languages, an
+increasingly important feature in a world using CGI scripts to deliver
+HTML.

+<p>
+<h1 align=center>What is Berkeley DB not?</h1>
+<p>In contrast to most other database systems, Berkeley DB provides relatively
+simple data access services.
+<p>Records in Berkeley DB are (<i>key</i>, <i>value</i>) pairs. Berkeley DB
+supports only a few logical operations on records. They are:
+<ul type=disc>
+<li>Insert a record in a table.
+<li>Delete a record from a table.
+<li>Find a record in a table by looking up its key.
+<li>Update a record that has already been found.
+</ul>
+<p>Notice that Berkeley DB never operates on the value part of a record.
+Values are simply payload, to be
+stored with keys and reliably delivered back to the application on
+demand.
+<p>Both keys and values can be arbitrary bit strings, either fixed-length
+or variable-length. As a result, programmers can put native programming
+language data structures into the database without converting them to
+a foreign record format first. Storage and retrieval are very simple,
+but the application needs to know what the structure of a key and a
+value is in advance. It cannot ask Berkeley DB, because Berkeley DB doesn't know.
+<p>This is an important feature of Berkeley DB, and one worth considering more
+carefully.  On the one hand, Berkeley DB cannot provide the programmer with
+any information on the contents or structure of the values that it
+stores.  The application must understand the keys and values that it
+uses.  On the other hand, there is literally no limit to the data types
+that can be store in a Berkeley DB database. The application never needs to
+convert its own program data into the data types that Berkeley DB supports.
+Berkeley DB is able to operate on any data type the application uses, no
+matter how complex.
+<p>Because both keys and values can be up to four gigabytes in length, a
+single record can store images, audio streams, or other large data
+values.  Large values are not treated specially in Berkeley DB. They are
+simply broken into page-sized chunks, and reassembled on demand when
+the application needs them. Unlike some other database systems, Berkeley DB
+offers no special support for binary large objects (BLOBs).
+<h3>Not a relational database</h3>
+<p>Berkeley DB is not a relational database.
+<p>First, Berkeley DB does not support SQL queries. All access to data is through
+the Berkeley DB API. Developers must learn a new set of interfaces in order
+to work with Berkeley DB. Although the interfaces are fairly simple, they are
+non-standard.
+<p>SQL support is a double-edged sword. One big advantage of relational
+databases is that they allow users to write simple declarative queries
+in a high-level language. The database system knows everything about
+the data and can carry out the command. This means that it's simple to
+search for data in new ways, and to ask new questions of the database.
+No programming is required.
+<p>On the other hand, if a programmer can predict in advance how an
+application will access data, then writing a low-level program to get
+and store records can be faster. It eliminates the overhead of query
+parsing, optimization, and execution. The programmer must understand
+the data representation, and must write the code to do the work, but
+once that's done, the application can be very fast.
+<p>Second, Berkeley DB has no notion of <i>schema</i> in the way that
+relational systems do. Schema is the structure of records in tables,
+and the relationships among the tables in the database. For example, in
+a relational system the programmer can create a record from a fixed menu
+of data types. Because the record types are declared to the system, the
+relational engine can reach inside records and examine individual values
+in them. In addition, programmers can use SQL to declare relationships
+among tables, and to create indexes on tables. Relational engines
+usually maintain these relationships and indexes automatically.
+<p>In Berkeley DB, the key and value in a record are opaque
+to Berkeley DB. They may have a rich
+internal structure, but the library is unaware of it. As a result, Berkeley DB
+cannot decompose the value part of a record into its constituent parts,
+and cannot use those parts to find values of interest. Only the
+application, which knows the data structure, can do that.
+<p>Berkeley DB does allow programmers to create indexes on tables, and to use
+those indexes to speed up searches. However, the programmer has no way
+to tell the library how different tables and indexes are related.  The
+application needs to make sure that they all stay consistent. In the
+case of indexes in particular, if the application puts a new record into
+a table, it must also put a new record in the index for it. It's
+generally simple to write a single function to make the required
+updates, but it is work that relational systems do automatically.
+<p>Berkeley DB is not a relational system. Relational database systems are
+semantically rich and offer high-level database access. Compared to such
+systems, Berkeley DB is a high-performance, transactional library for record
+storage. It's possible to build a relational system on top of Berkeley DB. In
+fact, the popular MySQL relational system uses Berkeley DB for
+transaction-protected table management, and takes care of all the SQL
+parsing and execution. It uses Berkeley DB for the storage level, and provides
+the semantics and access tools.
+<h3>Not an object-oriented database</h3>
+<p>Object-oriented databases are designed for very tight integration with
+object-oriented programming languages. Berkeley DB is written entirely in the
+C programming language. It includes language bindings for C++, Java,
+and other languages, but the library has no information about the
+objects created in any object-oriented application. Berkeley DB never makes
+method calls on any application object. It has no idea what methods are
+defined on user objects, and cannot see the public or private members
+of any instance.  The key and value part of all records are opaque to
+Berkeley DB.
+<p>Berkeley DB cannot automatically page in referenced objects, as some
+object-oriented databases do. The object-oriented application programmer
+must decide what records are required, and must fetch them by making
+method calls on Berkeley DB objects.
+<h3>Not a network database</h3>
+<p>Berkeley DB does not support network-style navigation among records, as
+network databases do. Records in a Berkeley DB table may move around over
+time, as new records are added to the table and old ones are deleted.
+Berkeley DB is able to do fast searches for records based on keys, but there
+is no way to create a persistent physical pointer to a record.
+Applications can only refer to records by key, not by address.
+<h3>Not a database server</h3>
+<p>Berkeley DB is not a standalone database server. It is a library, and runs in
+the address space of the application that uses it. If more than one
+application links in Berkeley DB, then all can use the same database at the
+same time; the library handles coordination among the applications, and
+guarantees that they do not interfere with one another.
+<p>Recent releases of Berkeley DB allow programmers to compile the library as a
+standalone process, and to use RPC stubs to connect to it and to carry
+out operations. However, there are some important limitations to this
+feature.  The RPC stubs provide exactly the same API that the library
+itself does.  There is no higher-level access provided by the standalone
+process. Tuning the standalone process is difficult, since Berkeley DB does
+no threading in the library (applications can be threaded, but the
+library never creates a thread on its own).
+<p>It is possible to build a server application that uses Berkeley DB for data
+management. For example, many commercial and open source Lightweight
+Directory Access Protocol (LDAP) servers use Berkeley DB for record storage.
+LDAP clients connect to these servers over the network. Individual
+servers make calls through the Berkeley DB API to find records and return them
+to clients. On its own, however, Berkeley DB is not a server.

+<h1 align=center>Do you need Berkeley DB?</h1>
+<p>Berkeley DB is an ideal database system for applications that need fast,
+scalable, and reliable embedded database management. For applications
+that need different services, however, it can be a poor choice.
+<p>First, do you need the ability to access your data in ways you cannot
+predict in advance? If your users want to be able to enter SQL
+queries to perform
+complicated searches that you cannot program into your application to
+begin with, then you should consider a relational engine instead. Berkeley DB
+requires a programmer to write code in order to run a new kind of query.
+<p>On the other hand, if you can predict your data access patterns up front
+-- and in particular if you need fairly simple key/value lookups -- then
+Berkeley DB is a good choice. The queries can be coded up once, and will then
+run very quickly because there is no SQL to parse and execute.
+<p>Second, are there political arguments for or against a standalone
+relational server? If you're building an application for your own use
+and have a relational system installed with administrative support
+already, it may be simpler to use that than to build and learn Berkeley DB.
+On the other hand, if you'll be shipping many copies of your application
+to customers, and don't want your customers to have to buy, install,
+and manage a separate database system, then Berkeley DB may be a better
+choice.
+<p>Third, are there any technical advantages to an embedded database? If
+you're building an application that will run unattended for long periods
+of time, or for end users who are not sophisticated administrators, then
+a separate server process may be too big a burden. It will require
+separate installation and management, and if it creates new ways for
+the application to fail, or new complexities to master in the field,
+then Berkeley DB may be a better choice.
+<p>The fundamental question is, how closely do your requirements match the
+Berkeley DB design? Berkeley DB was conceived and built to provide fast, reliable,
+transaction-protected record storage. The library itself was never
+intended to provide interactive query support, graphical reporting
+tools, or similar services that some other database systems provide. We
+have tried always to err on the side of minimalism and simplicity. By
+keeping the library small and simple, we create fewer opportunities for
+bugs to creep in, and we guarantee that the database system stays fast,
+because there is very little code to execute. If your application needs
+that set of features, then Berkeley DB is almost certainly the best choice
+for you.

+<h1 align=center>Sleepycat Software's Berkeley DB products</h1>
+<p>Sleepycat Software licenses three different products that use the Berkeley DB
+technology.  Each product offers a distinct level of database support.
+It is not possible to mix-and-match products, that is, each application
+or group of applications must use the same Berkeley DB product.
+<p>All three products are included in the single Open Source distribution of
+Berkeley DB from Sleepycat Software, and building that distribution
+automatically builds all three products.  Each product adds services, and
+new interfaces, to the product that precedes it in the list.  As a result,
+developers can download Berkeley DB and build an application that does only
+single-user, read-only database access, and later add support for more
+users and more complex database access patterns.
+<p>Users who distribute Berkeley DB must ensure that they are licensed for the
+Berkeley DB interfaces they use.  Information on licensing is available directly
+from Sleepycat Software.
+<h3>Berkeley DB Data Store</h3>
+<p>The Berkeley DB Data Store product is an embeddable, high-performance data store.  It
+supports multiple concurrent threads of control to read information
+managed by Berkeley DB.  When updates are required, only a single process may
+be using the database.  That process may be multi-threaded, but only one
+thread of control should be allowed to update the database at any time.
+The Berkeley DB Data Store does no locking, and so provides no guarantees of correct
+behavior if more than one thread of control is updating the database at
+a time.
+<p>The Berkeley DB Data Store product includes the <a href="../../api_c/db_create.html">db_create</a> interface, the
+DB handle methods, and the methods returned by <a href="../../api_c/db_cursor.html">DB-&gt;cursor</a>.
+<p>The Berkeley DB Data Store is intended for use in single-user or read-only applications
+that can guarantee that no more than one thread of control will ever
+update the database at any time.
+<h3>Berkeley DB Concurrent Data Store</h3>
+<p>The Berkeley DB Concurrent Data Store product adds multiple-reader, single writer capabilities to
+the Berkeley DB Data Store product, supporting applications that need concurrent updates
+and do not want to implement their own locking protocols.  The additional
+interfaces included with the Berkeley DB Concurrent Data Store product are <a href="../../api_c/env_create.html">db_env_create</a>, the
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> method (using the <a href="../../api_c/env_open.html#DB_INIT_CDB">DB_INIT_CDB</a> flag), and the
+<a href="../../api_c/env_close.html">DBENV-&gt;close</a> method.
+<p>Berkeley DB Concurrent Data Store is intended for applications that require occasional write access
+to a database that is largely used for reading.
+<h3>Berkeley DB Transactional Data Store</h3>
+<p>The Berkeley DB Transactional Data Store product adds full transactional support and recoverability
+to the Berkeley DB Data Store product.  This product includes all of the interfaces
+in the Berkeley DB library.
+<p>Berkeley DB Transactional Data Store is intended for applications that require industrial-strength
+database services, including good performance under high-concurrency
+workloads with a mixture of readers and writers, the ability to commit
+or roll back multiple changes to the database at a single instant, and
+the guarantee that even in the event of a catastrophic system or hardware
+failure, any committed database changes will be preserved.

+<p>
+<h1 align=center>Mapping the terrain: theory and practice</h1>
+<p>The first step in selecting a database system is figuring out what the
+choices are. Decades of research and real-world deployment have produced
+countless systems. We need to organize them somehow to reduce the number
+of options.
+<p>One obvious way to group systems is to use the common labels that
+vendors apply to them. The buzzwords here include "network,"
+"relational," "object-oriented," and "embedded," with some
+cross-fertilization like "object-relational" and "embedded network".
+Understanding the buzzwords is important. Each has some grounding in
+theory, but has also evolved into a practical label for categorizing
+systems that work in a certain way.
+<p>All database systems, regardless of the buzzwords that apply to them,
+provide a few common services.  All of them store data, for example.
+We'll begin by exploring the common services that all systems provide,
+and then examine the differences among the different kinds of systems.
+<h3>Data access and data management</h3>
+<p>Fundamentally, database systems provide two services.
+<p>The first service is <i>data access</i>. Data access means adding
+new data to the database (inserting), finding data of interest
+(searching), changing data already stored (updating), and removing data
+from the database (deleting). All databases provide these services. How
+they work varies from category to category, and depends on the record
+structure that the database supports.
+<p>Each record in a database is a collection of values. For example, the
+record for a Web site customer might include a name, email address,
+shipping address, and payment information. Records are usually stored
+in tables.  Each table holds records of the same kind. For example, the
+<b>customer</b> table at an e-commerce Web site might store the
+customer records for every person who shopped at the site. Often,
+database records have a different structure from the structures or
+instances supported by the programming language in which an application
+is written. As a result, working with records can mean:
+<ul type=disc>
+<li>using database operations like searches and updates on records; and
+<li>converting between programming language structures and database record
+types in the application.
+</ul>
+<p>The second service is <i>data management</i>. Data management is
+more complicated than data access. Providing good data management
+services is the hard part of building a database system.  When you
+choose a database system to use in an application you build, making sure
+it supports the data management services you need is critical.
+<p>Data management services include allowing multiple users to work on the
+database simultaneously (concurrency), allowing multiple records to be
+changed instantaneously (transactions), and surviving application and
+system crashes (recovery). Different database systems offer different
+data management services.  Data management services are entirely
+independent of the data access services listed above. For example,
+nothing about relational database theory requires that the system
+support transactions, but most commercial relational systems do.
+<p>Concurrency means that multiple users can operate on the database at
+the same time. Support for concurrency ranges from none (single-user
+access only) to complete (many readers and writers working
+simultaneously).
+<p>Transactions permit users to make multiple changes appear at once.  For
+example, a transfer of funds between bank accounts needs to be a
+transaction because the balance in one account is reduced and the
+balance in the other increases. If the reduction happened before the
+increase, than a poorly-timed system crash could leave the customer
+poorer; if the bank used the opposite order, then the same system crash
+could make the customer richer. Obviously, both the customer and the
+bank are best served if both operations happen at the same instant.
+<p>Transactions have well-defined properties in database systems. They are
+<i>atomic</i>, so that the changes happen all at once or not at all.
+They are <i>consistent</i>, so that the database is in a legal state
+when the transaction begins and when it ends. They are typically
+<i>isolated</i>, which means that any other users in the database
+cannot interfere with them while they are in progress. And they are
+<i>durable</i>, so that if the system or application crashes after
+a transaction finishes, the changes are not lost. Together, the
+properties of <i>atomicity</i>, <i>consistency</i>,
+<i>isolation</i>, and <i>durability</i> are known as the ACID
+properties.
+<p>As is the case for concurrency, support for transactions varies among
+databases. Some offer atomicity without making guarantees about
+durability.  Some ignore isolatability, especially in single-user
+systems; there's no need to isolate other users from the effects of
+changes when there are no other users.
+<p>Another important data management service is recovery. Strictly
+speaking, recovery is a procedure that the system carries out when it
+starts up. The purpose of recovery is to guarantee that the database is
+complete and usable. This is most important after a system or
+application crash, when the database may have been damaged. The recovery
+process guarantees that the internal structure of the database is good.
+Recovery usually means that any completed transactions are checked, and
+any lost changes are reapplied to the database.  At the end of the
+recovery process, applications can use the database as if there had been
+no interruption in service.
+<p>Finally, there are a number of data management services that permit
+copying of data. For example, most database systems are able to import
+data from other sources, and to export it for use elsewhere.  Also, most
+systems provide some way to back up databases and to restore in the
+event of a system failure that damages the database. Many commercial
+systems allow <i>hot backups</i>, so that users can back up
+databases while they are in use. Many applications must run without
+interruption, and cannot be shut down for backups.
+<p>A particular database system may provide other data management services.
+Some provide browsers that show database structure and contents. Some
+include tools that enforce data integrity rules, such as the rule that
+no employee can have a negative salary.  These data management services
+are not common to all systems, however. Concurrency, recovery, and
+transactions are the data management services that most database vendors
+support.
+<p>Deciding what kind of database to use means understanding the data
+access and data management services that your application needs.  Berkeley DB
+is an embedded database that supports fairly simple data access with a
+rich set of data management services. To highlight its strengths and
+weaknesses, we can compare it to other database system categories.
+<h3>Relational databases</h3>
+<p>Relational databases are probably the best-known database variant,
+because of the success of companies like Oracle. Relational databases
+are based on the mathematical field of set theory.  The term "relation"
+is really just a synonym for "set" -- a relation is just a set of
+records or, in our terminology, a table. One of the main innovations in
+early relational systems was to insulate the programmer from the
+physical organization of the database. Rather than walking through
+arrays of records or traversing pointers, programmers make statements
+about tables in a high-level language, and the system executes those
+statements.
+<p>Relational databases operate on <i>tuples</i>, or records, composed
+of values of several different data types, including integers, character
+strings, and others. Operations include searching for records whose
+values satisfy some criteria, updating records, and so on.
+<p>Virtually all relational databases use the Structured Query Language,
+or SQL. This language permits people and computer programs to work with
+the database by writing simple statements. The database engine reads
+those statements and determines how to satisfy them on the tables in
+the database.
+<p>SQL is the main practical advantage of relational database systems.
+Rather than writing a computer program to find records of interest, the
+relational system user can just type a query in a simple syntax, and
+let the engine do the work. This gives users enormous flexibility; they
+do not need to decide in advance what kind of searches they want to do,
+and they do not need expensive programmers to find the data they need.
+Learning SQL requires some effort, but it's much simpler than a
+full-blown high-level programming language for most purposes. And there
+are a lot of programmers who have already learned SQL.
+<h3>Object-oriented databases</h3>
+<p>Object-oriented databases are less common than relational systems, but
+are still fairly widespread. Most object-oriented databases were
+originally conceived as persistent storage systems closely wedded to
+particular high-level programming languages like C++. With the spread
+of Java, most now support more than one programming language, but
+object-oriented database systems fundamentally provide the same class
+and method abstractions as do object-oriented programming languages.
+<p>Many object-oriented systems allow applications to operate on objects
+uniformly, whether they are in memory or on disk. These systems create
+the illusion that all objects are in memory all the time.  The advantage
+to object-oriented programmers who simply want object storage and
+retrieval is clear. They need never be aware of whether an object is in
+memory or not.  The application simply uses objects, and the database
+system moves them between disk and memory transparently.  All of the
+operations on an object, and all its behavior, are determined by the
+programming language.
+<p>Object-oriented databases aren't nearly as widely deployed as relational
+systems. In order to attract developers who understand relational
+systems, many of the object-oriented systems have added support for
+query languages very much like SQL. In practice, though, object-oriented
+databases are mostly used for persistent storage of objects in C++ and
+Java programs.
+<h3>Network databases</h3>
+<p>The "network model" is a fairly old technique for managing and
+navigating application data. Network databases are designed to make
+pointer traversal very fast. Every record stored in a network database
+is allowed to contain pointers to other records. These pointers are
+generally physical addresses, so fetching the referenced record just
+means reading it from disk by its disk address.
+<p>Network database systems generally permit records to contain integers,
+floating point numbers, and character strings, as well as references to
+other records. An application can search for records of interest. After
+retrieving a record, the application can fetch any referenced record
+quickly.
+<p>Pointer traversal is fast because most network systems use physical disk
+addresses as pointers. When the application wants to fetch a record,
+the database system uses the address to fetch exactly the right string
+of bytes from the disk. This requires only a single disk access in all
+cases. Other systems, by contrast, often must do more than one disk read
+to find a particular record.
+<p>The key advantage of the network model is also its main drawback. The
+fact that pointer traversal is so fast means that applications that do
+it will run well. On the other hand, storing pointers all over the
+database makes it very hard to reorganize the database. In effect, once
+you store a pointer to a record, it is difficult to move that record
+elsewhere.  Some network databases handle this by leaving forwarding
+pointers behind, but this defeats the speed advantage of doing a single
+disk access in the first place. Other network databases find, and fix,
+all the pointers to a record when it moves, but this makes
+reorganization very expensive. Reorganization is often necessary in
+databases, since adding and deleting records over time will consume
+space that cannot be reclaimed without reorganizing. Without periodic
+reorganization to compact network databases, they can end up with a
+considerable amount of wasted space.
+<h3>Clients and servers</h3>
+<p>Database vendors have two choices for system architecture. They can
+build a server to which remote clients connect, and do all the database
+management inside the server. Alternatively, they can provide a module
+that links directly into the application, and does all database
+management locally.  In either case, the application developer needs
+some way of communicating with the database (generally, an Application
+Programming Interface (API) that does work in the process or that
+communicates with a server to get work done).
+<p>Almost all commercial database products are implemented as servers, and
+applications connect to them as clients. Servers have several features
+that make them attractive.
+<p>First, because all of the data is managed by a separate process, and
+possibly on a separate machine, it's easy to isolate the database server
+from bugs and crashes in the application.
+<p>Second, because some database products (particularly relational engines)
+are quite large, splitting them off as separate server processes keeps
+applications small, which uses less disk space and memory. Relational
+engines include code to parse SQL statements, to analyze them and
+produce plans for execution, to optimize the plans, and to execute
+them.
+<p>Finally, by storing all the data in one place and managing it with a
+single server, it's easier for organizations to back up, protect, and
+set policies on their databases. The enterprise databases for large
+companies often have several full-time administrators caring for them,
+making certain that applications run quickly, granting and denying
+access to users, and making backups.
+<p>However, centralized administration can be a disadvantage in some cases.
+In particular, if a programmer wants to build an application that uses
+a database for storage of important information, then shipping and
+supporting the application is much harder. The end user needs to install
+and administer a separate database server, and the programmer must
+support not just one product, but two. Adding a server process to the
+application creates new opportunity for installation mistakes and
+run-time problems.

+<h1 align=center>What other services does Berkeley DB provide?</h1>
+<p>Berkeley DB also provides core database services to developers.  These
+services include:
+<p><dl compact>
+<p><dt>Page cache management:<dd>The page cache provides fast access to a cache of database pages,
+handling the I/O associated with the cache to ensure that dirty pages
+are written back to the file system and that new pages are allocated on
+demand.  Applications may use the Berkeley DB shared memory buffer manager to
+serve their own files and pages.
+<p><dt>Transactions and logging:<dd>The transaction and logging systems provide recoverability and atomicity
+for multiple database operations. The transaction system uses two-phase
+locking and write-ahead logging protocols to ensure that database
+operations may be undone or redone in the case of application or system
+failure.  Applications may use Berkeley DB transaction and logging subsystems
+to protect their own data structures and operations from application or
+system failure.
+<p><dt>Locking:<dd>The locking system provides multiple reader or single writer access to
+objects.  The Berkeley DB access methods use the locking system to acquire
+the right to read or write database pages.  Applications may use the
+Berkeley DB locking subsystem to support their own locking needs.
+</dl>
+<p>By combining the page cache, transaction, locking, and logging systems,
+Berkeley DB provides the same services found in much larger, more complex and
+more expensive database systems.  Berkeley DB supports multiple simultaneous
+readers and writers and guarantees that all changes are recoverable, even
+in the case of a catastrophic hardware failure during a database update.
+<p>Developers may select some or all of the core database services for any
+access method or database.  Therefore, it is possible to choose the
+appropriate storage structure and the right degrees of concurrency and
+recoverability for any application.  In addition, some of the systems
+(e.g., the locking subsystem) can be called separately from the Berkeley DB
+access method.  As a result, developers can integrate non-database
+objects into their transactional applications using Berkeley DB.

+<h1 align=center>Compatibility</h1>
+<p>The Berkeley DB Java API has been tested with the
+<a href="http://www.javasoft.com">Sun Microsystems JDK 1.1.3</a> on SunOS
+5.5, and Sun's JDK 1.1.7, JDK 1.2.2 and JDK 1.3.0 on Linux and
+Windows/NT.  It should work with any JDK 1.1, 1.2 or 1.3 (the latter
+two are known as Java 2) compatible environment.  IBM's VM 1.3.0 has
+also been tested on Linux.
+<p>The primary requirement of the Berkeley DB Java API is that the target Java
+environment supports JNI (Java Native Interface), rather than another
+method for allowing native C/C++ code to interface to Java. The JNI was
+new in JDK 1.1, but is the most likely interface to be implemented across
+multiple platforms.  However, using the JNI means that Berkeley DB will not be
+compatible with Microsoft Visual J++.

+<h1 align=center>Configuration</h1>
+<p>Building the Berkeley DB java classes, the examples and the native support
+library is integrated into the normal build process.  See
+<a href="../../ref/build_unix/conf.html#--enable-java">Configuring
+Berkeley DB</a> and <a href="../../ref/build_win/intro.html">Building for Windows</a>
+for more information.
+<p>We expect that you've already installed the Java JDK or equivalent on
+your system.  For the sake of discussion, we'll assume it is in a
+directory called db-VERSION, e.g., you extracted Berkeley DB version 2.3.12
+and you did not change the top-level directory name.  The files related
+to Java are in two subdirectories of db-VERSION: java, the java source
+files, and libdb_java, the C++ files that provide the "glue" between
+java and Berkeley DB.  The directory tree looks like this:
+<p><blockquote><pre>		db-VERSION
+	       /          \
+	    java        libdb_java
+	     |              |
+	    src            ...
+	     |
+	    com
+	     |
+	 sleepycat
+	/         \
+       db       examples
+       |           |
+      ...         ...
+</pre></blockquote>
+<p>This naming conforms to the emerging standard for naming java packages.
+When the java code is built, it is placed into a <b>classes</b>
+subdirectory that is parallel to the <b>src</b> subdirectory.
+<p>For your application to use Berkeley DB successfully, you must set your
+CLASSPATH environment variable to include db-VERSION/java/classes as
+well as the classes in your java distribution.  On UNIX, CLASSPATH is
+a colon separated list of directories; on Windows it is separated by
+semicolons.  Alternatively, you can set your CLASSPATH to include
+db-VERSION/java/classes/db.jar which is created as a result of the
+build.  The db.jar file contains the classes in com.sleepycat.db, it
+does not contain any classes in com.sleepycat.examples.
+<p>On Windows, you will want to set your PATH variable to include:
+<p><blockquote><pre>db-VERSION\build_win32\Release</pre></blockquote>
+<p>On UNIX, you will want to set the LD_LIBRARY_PATH environment variable
+to include the Berkeley DB library installation directory. Of course, the
+standard install directory may have been changed for your site, see your
+system administrator for details.  Regardless, if you get a:
+<p><blockquote><pre>java.lang.UnsatisfiedLinkError</pre></blockquote>
+<p>exception when you run, chances are you do not have the library search
+path configured correctly.  Different Java interpreters provide
+different error messages if the CLASSPATH value is incorrect, a typical
+error is:
+<p><blockquote><pre>java.lang.NoClassDefFoundError</pre></blockquote>
+<p>To ensure that everything is running correctly, you may want to try a
+simple test from the example programs in:
+<p><blockquote><pre>db-VERSION/java/src/com/sleepycat/examples</pre></blockquote>
+<p>For example, the sample program:
+<p><blockquote><pre>% java com.sleepycat.examples.AccessExample</pre></blockquote>
+<p>will prompt for text input lines which are then stored in a Btree
+database named "access.db" in your current directory.  Try giving it a
+few lines of input text and then end-of-file.  Before it exits, you
+should see a list of the lines you entered display with data items.
+This is a simple check to make sure the fundamental configuration is
+working correctly.

+<h1 align=center>Java Programming Notes</h1>
+<p>The Java API closely parallels the Berkeley DB C++ and C interfaces.  If you
+are currently using either of those APIs, there will be very little to
+surprise you in the Java API.  We have even taken care to make the names
+of classes, constants, methods and arguments identical, where possible,
+across all three APIs.
+<p><ol>
+<p><li>The Java runtime does not automatically close Berkeley DB objects on
+finalization.  There are a couple reasons for this.  One is that
+finalization is generally run only when garbage collection occurs and
+there is no guarantee that this occurs at all, even on exit.  Allowing
+specific Berkeley DB actions to occur in ways that cannot be replicated seems
+wrong.  Secondly, finalization of objects may happen in an arbitrary
+order, so we would have to do extra bookkeeping to make sure everything
+was closed in the proper order.  The best word of advice is to always
+do a close() for any matching open() call.  Specifically, the Berkeley DB
+package requires that you explicitly call close on each individual
+<a href="../../api_java/db_class.html">Db</a> and <a href="../../api_java/dbc_class.html">Dbc</a> object that you opened.  Your database
+activity may not be synchronized to disk unless you do so.
+<p><li>Some methods in the Java API have no return type, and throw a
+<a href="../../api_java/except_class.html">DbException</a> when an severe error arises.  There are some notable
+methods that do have a return value, and can also throw an exception.
+<a href="../../api_java/db_get.html">Db.get</a> and <a href="../../api_java/dbc_get.html">Dbc.get</a> both return 0 when a get succeeds,
+<a href="../../ref/program/errorret.html#DB_NOTFOUND">Db.DB_NOTFOUND</a> when the key is not found, and throw an error when
+there is a severe error.  This approach allows the programmer to check
+for typical data driven errors by watching return values without special
+casing exceptions.
+<p>An object of type <a href="../../api_java/deadlock_class.html">DbDeadlockException</a> is thrown when a deadlock
+would occur.
+<p>An object of type <a href="../../api_java/mem_class.html">DbMemoryException</a> is thrown when the system
+cannot provide enough memory to complete the operation (the ENOMEM
+system error on UNIX).
+<p>An object of type <a href="../../api_java/runrec_class.html">DbRunRecoveryException</a>, a subclass of
+<a href="../../api_java/except_class.html">DbException</a>, is thrown when there is an error that requires a
+recovery of the database, using <a href="../../utility/db_recover.html">db_recover</a>.
+<p><li>There is no class corresponding to the C++ DbMpoolFile class in the Berkeley DB
+Java API.  There is a subset of the memp_XXX methods in the <a href="../../api_java/dbenv_class.html">DbEnv</a>
+class.  This has been provided to allow you to perform certain
+administrative actions on underlying memory pools opened as a consequence
+of <a href="../../api_java/env_open.html">DbEnv.open</a>.  Direct access to other memory pool functionality
+is not appropriate for the Java environment.
+<p><li>Berkeley DB always turns on the <a href="../../api_java/env_open.html#DB_THREAD">Db.DB_THREAD</a> flag since threads
+are expected in Java.
+<p><li>If there are embedded null strings in the <b>curslist</b> argument for
+<a href="../../api_java/db_join.html">Db.join</a>, they will be treated as the end of the list of
+cursors, even though you may have allocated a longer array.  Fill in
+all the strings in your array unless you intend to cut it short.
+<p><li>The callback installed for <a href="../../api_java/env_set_errcall.html">DbEnv.set_errcall</a> will run in the same
+thread as the caller to <a href="../../api_java/env_set_errcall.html">DbEnv.set_errcall</a>.  Make sure that thread
+remains running until your application exits or <a href="../../api_java/env_close.html">DbEnv.close</a> is
+called.

+<h1 align=center>Access method locking conventions</h1>
+<p>All the Berkeley DB access methods follow the same conventions for locking
+database objects.  Applications that do their own locking and also do
+locking via the access methods must be careful to adhere to these
+conventions.
+<p>Whenever a Berkeley DB database is opened, the DB handle is
+assigned a unique locker ID.  Unless transactions are specified,
+that ID is used as the locker for all calls that the Berkeley DB methods
+make to the lock subsystem.  In order to lock a file,  pages in
+the file, or records in the file, we must create a unique ID that
+can be used as the object to be locked in calls to the lock manager.
+Under normal operation, that object is a 28-byte value, created by
+the concatenation of a unique file identifier, a page or record number,
+and an object type (page or record).
+<p>In a transaction-protected environment, database create and delete
+operations are recoverable and single-threaded.  This single-threading is
+achieved using a single lock for the entire environment that must be
+acquired before beginning a create or delete operation.  In this case,
+the object on which Berkeley DB will lock is a 32-bit unsigned integer with a
+value of 0.
+<p>If applications are using the lock subsystem directly while they are also
+using locking via the access methods, they must take care not to
+inadvertently lock objects that happen to be equal to the unique file IDs
+used to lock files.  This is most easily accomplished by using a locker
+ID of a different length than the values used by Berkeley DB.
+<p>All of the access methods other than Queue use a simple
+multiple-reader/single writer page locking scheme.  The standard
+read/write locks (<b>DB_LOCK_READ</b> and <b>DB_LOCK_WRITE</b>) and
+conflict matrix, as described in <a href="../../ref/lock/stdmode.html">Standard lock modes</a> are used.  An operation that returns data (e.g.,
+<a href="../../api_c/db_get.html">DB-&gt;get</a>, <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a>) obtains a read lock on all the pages
+accessed while locating the requested record.   When an update operation
+is requested (e.g., <a href="../../api_c/db_put.html">DB-&gt;put</a>, <a href="../../api_c/dbc_del.html">DBcursor-&gt;c_del</a>), the page containing
+the updated (or new) data is write locked.  As read-modify-write cycles
+are quite common and are deadlock prone under normal circumstances, the
+Berkeley DB interfaces allow the application to specify the <a href="../../api_c/dbc_get.html#DB_RMW">DB_RMW</a> flag,
+which causes operations to immediately obtain a writelock, even though
+they are only reading the data.  While this may reduce concurrency
+somewhat, it reduces the probability of deadlock.
+<p>The Queue access method does not hold long term page locks.
+Instead, page locks are held only long enough to locate records or to change
+metadata on a page, and record locks are held for the appropriate duration.
+In the presence of transactions, record locks are held until transaction
+commit.
+For Berkeley DB operations, record locks are held until operation
+completion and for DBC operations, record locks are held until
+subsequent records are returned or the cursor is closed.
+<p>Under non-transaction operation, the access methods do not normally hold
+locks across calls to the Berkeley DB interfaces.  The one exception to this
+rule is when cursors are used.  As cursors maintain a position in a file,
+they must hold locks across calls and will, in fact, hold locks until the
+cursor is closed.  Furthermore, each cursor is assigned its own unique
+locker ID when it is created, so cursor operations can conflict with one
+another.  (Each cursor is assigned its own locker ID because Berkeley DB handles
+may be shared by multiple threads of control.  The Berkeley DB library cannot
+identify which operations are performed by which threads of control, and
+it must ensure that two different threads of control are not
+simultaneously modifying the same data structure.  By assigning each
+cursor its own locker, two threads of control sharing a handle cannot
+inadvertently interfere with each other.
+<p>This has important implications.  If a single thread of control opens two
+cursors or uses a combination of cursor and non-cursor operations, these
+operations are performed on behalf of different lockers.  Conflicts that
+arise between these different lockers may not cause actual deadlocks, but
+can, in fact, permanently block the thread of control.  For example,
+assume that an application creates a cursor and uses it to read record A.
+Now assume a second cursor is opened and the application attempts to write
+record A using the second cursor.  Unfortunately, the first cursor has a
+read lock so the second cursor cannot obtain its write lock.  However,
+that read lock is held by the same thread of control, so if we block
+waiting for the write lock, the read lock can never be released.  This
+might appear to be a deadlock from the application's perspective, but
+Berkeley DB cannot identify it as such because it has no knowledge of which
+lockers belong to which threads of control.  For this reason, application
+designers are encouraged to close cursors as soon as they are done with
+them.
+<p>Complicated operations that require multiple cursors (or combinations of
+cursor and non-cursor operations) can be performed in two ways.  First,
+they may be performed within a transaction, in which case all operations
+lock on behalf of the designated locker ID.  Alternatively, the
+<a href="../../api_c/dbc_dup.html">DBcursor-&gt;c_dup</a> function duplicates a cursor, using the same locker ID as
+the originating cursor.  There is no way to achieve this duplication
+functionality through the DB handle calls, but any DB call can be
+implemented by one or more calls through a cursor.
+<p>When the access methods use transactions, many of these problems disappear.
+The transaction ID is used as the locker ID for all operations performed
+on behalf of the transaction.  This means that the application may open
+multiple cursors on behalf of the same transaction and these cursors will
+all share a common locker ID.  This is safe because transactions cannot
+span threads of control, so the library knows that two cursors in the same
+transaction cannot modify the database concurrently.
+<p>As mentioned earlier, most of the Berkeley DB access methods use page level
+locking.  During Btree traversal, lock-coupling is used to traverse the
+tree.  Note that the tree traversal that occurs during an update operation
+can also use lock-coupling; it is not necessary to retain locks on
+internal Btree pages even if the item finally referenced will be updated.
+Even in the presence of transactions, locks obtained on internal pages of
+the Btree may be safely released as the traversal proceeds.  This greatly
+improves concurrency.  The only time internal locks become crucial is when
+internal pages are split or merged.  When traversing duplicate data items
+for a key, the lock on the key value also acts as a lock on all duplicates
+of that key.  Therefore, two conflicting threads of control cannot access
+the same duplicate set simultaneously.
+<p>The Recno access method uses a Btree as its underlying data
+representation and follows similar locking conventions.  However, as the
+Recno access method must keep track of the number of children for all
+internal pages, it must obtain write locks on all internal pages during
+read and write operations.  In the presence of transactions, these locks
+are not released until transaction commit.

+<h1 align=center>Berkeley DB Concurrent Data Store locking conventions</h1>
+<p>The Berkeley DB Concurrent Data Store product has a different set of conventions for locking.  It
+provides multiple reader/single writer semantics, but not per-page locking
+or transaction recoverability.  As such, it does its locking entirely at
+the interface to the access methods.
+<p>The object it locks is the file, identified by its unique file number.
+The locking matrix is not one of the two standard lock modes, instead,
+we use a four-lock set, consisting of:
+<p><dl compact>
+<p><dt>DB_LOCK_NG<dd>not granted (always 0)
+<dt>DB_LOCK_READ<dd>read (shared)
+<dt>DB_LOCK_WRITE<dd>write (exclusive)
+<dt>DB_LOCK_IWRITE<dd>intention-to-write (shared with NG and READ, but conflicts with WRITE and IWRITE)
+</dl>
+<p>The IWRITE lock is used for cursors that will be used for updating (IWRITE
+locks are implicitly obtained for write operations through the Berkeley DB
+handles, e.g., <a href="../../api_c/db_put.html">DB-&gt;put</a>, <a href="../../api_c/db_del.html">DB-&gt;del</a>).  While the cursor is
+reading, the IWRITE lock is held, but as soon as the cursor is about to
+modify the database, the IWRITE is upgraded to a WRITE lock.  This upgrade
+blocks until all readers have exited the database.  Because only one
+IWRITE lock is allowed at any one time, no two cursors can ever try to
+upgrade to a WRITE lock at the same time, and therefore deadlocks are
+prevented, which is essential as Berkeley DB Concurrent Data Store does not include deadlock
+detection and recovery.
+<p>Applications that need to lock compatibly with Berkeley DB Concurrent Data Store must obey the
+following rules:
+<p><ol>
+<p><li>Use only lock modes DB_LOCK_NG, DB_LOCK_READ, DB_LOCK_WRITE,
+DB_LOCK_IWRITE.
+<p><li>Never attempt to acquire a WRITE lock on an object that is
+already locked with a READ lock.
+</ol>

+<h1 align=center>Configuring locking</h1>
+<p>The <a href="../../api_c/env_set_lk_detect.html">DBENV-&gt;set_lk_detect</a> function specifies that the deadlock detector
+should be run whenever a lock blocks.  This option provides for rapid
+detection of deadlocks at the expense of potentially frequent
+invocations of the deadlock detector.  On a fast processor with a highly
+contentious application, where response time is critical, this is a good
+choice.  An argument to the <a href="../../api_c/env_set_lk_detect.html">DBENV-&gt;set_lk_detect</a> function indicates which
+transaction to abort when a deadlock is detected.  It can take on any
+one of the following values:
+<p><dl compact>
+<p><dt><a href="../../api_c/env_set_lk_detect.html#DB_LOCK_YOUNGEST">DB_LOCK_YOUNGEST</a><dd>Abort the most recently started transaction.
+<dt><a href="../../api_c/env_set_lk_detect.html#DB_LOCK_OLDEST">DB_LOCK_OLDEST</a><dd>Abort the longest lived transaction.
+<dt><a href="../../api_c/env_set_lk_detect.html#DB_LOCK_RANDOM">DB_LOCK_RANDOM</a><dd>Abort whatever transaction the deadlock detector happens to find first.
+<dt><a href="../../api_c/env_set_lk_detect.html#DB_LOCK_DEFAULT">DB_LOCK_DEFAULT</a><dd>Use the default policy (currently DB_RANDOM).
+</dl>
+<p>In general, <a href="../../api_c/env_set_lk_detect.html#DB_LOCK_DEFAULT">DB_LOCK_DEFAULT</a> is probably the correct choice.  If
+an application has long-running transactions, then
+<a href="../../api_c/env_set_lk_detect.html#DB_LOCK_YOUNGEST">DB_LOCK_YOUNGEST</a> will guarantee that transactions eventually
+complete, but it may do so at the expense of a large number of aborts.
+<p>The alternative to using the <a href="../../api_c/env_set_lk_detect.html">DBENV-&gt;set_lk_detect</a> interface is
+to run the deadlock detector manually, using the Berkeley DB
+<a href="../../api_c/lock_detect.html">lock_detect</a> interface.
+<p>The <a href="../../api_c/env_set_lk_conflicts.html">DBENV-&gt;set_lk_conflicts</a> function allows you to specify your own locking
+conflicts matrix.  This is an advanced configuration option, and rarely
+necessary.

+<p>
+<h1 align=center>Deadlocks and deadlock avoidance</h1>
+<p>Practically any application that uses locking may deadlock.
+In nearly all cases, in order to recover from a deadlock, transactions
+must be used, so that an operation that deadlocks mid-way through can
+be undone, leaving the database in a consistent state.
+As the access methods may perform updates on multiple pages during a
+single API call, transactions are necessary even when the application
+makes only single update calls into the database.
+The only exception to this rule is when all the threads accessing
+the database are doing so read-only or when the Concurrent Data Store
+product is used; this product guarantees deadlock-free operation at the
+expense of reduced concurrency.
+Since deadlocks cannot  be prevented, Berkeley DB provides the ability to detect
+deadlocks and recover from them gracefully.
+<p>Deadlocks occur when two or more threads of control are blocked waiting
+on each other's forward progress.  Consider two transactions, each of
+which wants to modify items A and B.  Assume that transaction 1 modifies
+first A and then B, but transaction 2 modifies B then A.  Now, assume
+that transaction 1 obtains its writelock on A, but before it obtains its
+writelock on B, it is descheduled and transaction 2 runs.  Transaction 2
+successfully acquires its writelock on B, but then blocks when it tries
+to obtain its writelock on A, because transaction 1 already holds a
+writelock on it.  This is a deadlock. Transaction 1 cannot make forward
+progress until Transaction 2 releases its lock on B, but Transaction 2
+cannot make forward progress until Transaction 1 releases its lock on A.
+<p>The <a href="../../api_c/lock_detect.html">lock_detect</a> function runs an instance of the Berkeley DB deadlock
+detector.  The <a href="../../utility/db_deadlock.html">db_deadlock</a> utility performs deadlock detection by
+calling <a href="../../api_c/lock_detect.html">lock_detect</a> at regular intervals.  When a deadlock exists
+in the system, all of the threads of control involved in the deadlock are,
+by definition, waiting on a lock.  The deadlock detector examines the
+state of the lock manager and identifies a deadlock, and selects one of
+the participants to abort.  (See <a href="../../ref/lock/config.html">Configuring locking</a> for a discussion of how a participant is selected).
+The lock on which the selected participant is waiting is identified such
+that the <a href="../../api_c/lock_get.html">lock_get</a> (or <a href="../../api_c/lock_vec.html">lock_vec</a>) call in which that lock
+was requested will receive an error return of <a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a>.
+In the access methods, this error return is propagated back through the
+Berkeley DB interface as DB_LOCK_DEADLOCK.
+<p>When an application receives an DB_LOCK_DEADLOCK, the correct action is
+to abort the current transaction, and optionally retry it.  Transaction
+support is necessary for recovery from deadlocks.  When a deadlock occurs,
+the database may be left in an inconsistent or corrupted state, and any
+database changes already accomplished must be undone before the
+application can proceed further.
+<p>The deadlock detector identifies deadlocks by looking for a cycle in what
+is commonly referred to as its "waits-for" graph.  More precisely, the
+deadlock detector reads through the lock table, and finds each object
+currently locked.  Each object has a list of transactions or operations
+(hereafter called lockers) that currently hold locks on the object and
+possibly a list of waiting lockers, waiting on the lockers holding it.
+Each object creates one or more partial orderings of lockers.  That is,
+for a particular object, every waiting locker comes after every holding
+locker, because that holding locker must release its lock before the
+waiting locker can make forward progress.  Conceptually, after each object
+has been examined, the partial orderings are topologically sorted (see
+tsort).  If this topological sort reveals any cycles, then the lockers
+forming the cycle are involved in a deadlock.  One of the lockers is
+selected for abortion.
+<p>It is possible that aborting a single transaction involved in a deadlock
+is not enough to allow other transactions to make forward progress.
+In this case, the deadlock detector will be called repeatedly.
+Unfortunately, at the time a transaction is selected for abortion,
+there is not enough information available to determine if aborting
+that single transaction will allow forward progress or not.  Since
+most applications have few deadlocks, Berkeley DB takes the conservative
+approach, aborting as few transactions as may be necessary to resolve
+the existing deadlocks.  In particular, for each unique cycle found
+in the waits-for graph described in the previous paragraph, only one
+transaction is selected for abortion.  However, if there are multiple
+cycles, then one transaction from each cycle is selected for abortion.
+Only after the aborting transactions have received the deadlock return
+and aborted their transactions, can it be determined if it is necessary
+to abort other transactions in order to allow forward progress.

+<h1 align=center>Berkeley DB and locking</h1>
+<p>The lock subsystem provides interprocess and intraprocess concurrency
+control mechanisms.  While the locking system is used extensively by the
+Berkeley DB access methods and transaction system, it may also be used as a
+stand-alone subsystem to provide concurrency control to any set of
+designated resources.
+<p>The lock subsystem is created, initialized, and opened by calls to
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> with the <a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a> or <a href="../../api_c/env_open.html#DB_INIT_CDB">DB_INIT_CDB</a>
+flags specified.
+<p>The <a href="../../api_c/lock_detect.html">lock_detect</a> function provides the programmatic interface to
+the Berkeley DB deadlock detector.  Whenever two threads of control issue lock
+requests that are not carefully ordered or that require upgrading locks
+(obtaining write locks on objects that are already read-locked), the
+possibility for deadlock arises.  A deadlock occurs when two or more
+threads of control are blocked, waiting for actions that another one of
+these blocked threads must take.  For example, assume that threads one
+and two have each obtained read locks on object A.  Now suppose that both
+threads wish to obtain write locks on object A.  Neither thread can be
+granted its writelock (because of the other thread's readlock).  Both
+threads block and will never unblock because the event for which they are
+waiting can never happen.
+<p>The deadlock detector examines all the locks held in the environment and
+identifies situations where no thread can make forward progress.  It then
+selects one of the participants in the deadlock (according to the argument
+that was specified to <a href="../../api_c/env_set_lk_detect.html">DBENV-&gt;set_lk_detect</a>) and forces it to return
+the value DB_LOCK_DEADLOCK, which indicates that a deadlock occurred.
+The thread receiving such an error should abort its current transaction,
+or simply release all its locks if it is not running in a transaction,
+and retry the operation.
+<p>The <a href="../../api_c/lock_vec.html">lock_vec</a> interface is used to acquire and release locks.
+<p>Two additional interfaces, <a href="../../api_c/lock_get.html">lock_get</a> and <a href="../../api_c/lock_put.html">lock_put</a>, are
+provided.  These interfaces are simpler front-ends to the <a href="../../api_c/lock_vec.html">lock_vec</a>
+functionality, where <a href="../../api_c/lock_get.html">lock_get</a> acquires a lock, and
+<a href="../../api_c/lock_put.html">lock_put</a> releases a lock that was acquired using <a href="../../api_c/lock_get.html">lock_get</a>
+or <a href="../../api_c/lock_vec.html">lock_vec</a>.
+<p>It is up to the application to specify lockers and objects appropriately.
+When used with the Berkeley DB access methods, these lockers and objects are
+handled completely internally, but an application using the lock manager
+directly must either use the same conventions as the access methods or
+define its own convention to which it adheres.  If the application is
+using the access methods with locking at the same time that it is calling
+the lock manager directly, the application must follow a convention that
+is compatible with the access methods' use of the locking subsystem.  See
+<a href="../../ref/lock/am_conv.html">Access method locking conventions</a>
+for more information.
+<p>The <a href="../../api_c/lock_id.html">lock_id</a> function returns a unique ID which may safely be used
+as the locker parameter to the <a href="../../api_c/lock_vec.html">lock_vec</a> interface.  The access
+methods use <a href="../../api_c/lock_id.html">lock_id</a> to generate unique lockers for the cursors
+associated with a database.
+<p>The <a href="../../api_c/lock_vec.html">lock_vec</a> function performs any number of lock operations
+atomically.  It also provides the ability to release all locks held by a
+particular locker and release all the locks on a particular object.
+Performing multiple lock operations atomically is useful in performing
+Btree traversals where you want to acquire a lock on a child page and once
+acquired, immediately release the lock on its parent (this is
+traditionally referred to as "lock-coupling").  Using <a href="../../api_c/lock_vec.html">lock_vec</a>
+instead of separate calls to <a href="../../api_c/lock_put.html">lock_put</a> and <a href="../../api_c/lock_get.html">lock_get</a> reduces
+the synchronization overhead between multiple threads or processes.
+<p>The three interfaces, <a href="../../api_c/lock_get.html">lock_get</a>, <a href="../../api_c/lock_put.html">lock_put</a> and <a href="../../api_c/lock_vec.html">lock_vec</a>,
+are fully compatible, and may be used interchangeably.
+<p>All locks explicitly requested by an application should be released via
+calls to <a href="../../api_c/lock_put.html">lock_put</a> or <a href="../../api_c/lock_vec.html">lock_vec</a>.
+<p>The <a href="../../api_c/lock_stat.html">lock_stat</a> function returns information about the status of
+the lock subsystem.  It is the programmatic interface used by the
+<a href="../../utility/db_stat.html">db_stat</a> utility.
+<p>The locking subsystem is closed by the call to <a href="../../api_c/env_close.html">DBENV-&gt;close</a>.
+<p>Finally, the entire locking subsystem may be discarded using the
+<a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> interface.

+<h1 align=center>Configuring locking: sizing the system</h1>
+<p>The lock system is sized using the following three functions:
+<p><blockquote><pre><a href="../../api_c/env_set_lk_max_locks.html">DBENV-&gt;set_lk_max_locks</a>
+<a href="../../api_c/env_set_lk_max_lockers.html">DBENV-&gt;set_lk_max_lockers</a>
+<a href="../../api_c/env_set_lk_max_objects.html">DBENV-&gt;set_lk_max_objects</a></pre></blockquote>
+<p>The <a href="../../api_c/env_set_lk_max_locks.html">DBENV-&gt;set_lk_max_locks</a>, <a href="../../api_c/env_set_lk_max_lockers.html">DBENV-&gt;set_lk_max_lockers</a>
+and <a href="../../api_c/env_set_lk_max_objects.html">DBENV-&gt;set_lk_max_objects</a> functions specify, respectively, the
+maximum number of locks, lockers and locked objects supported by the
+lock subsystem.  The maximum number of locks is the number of locks that
+can be simultaneously requested in the system.  The maximum number of
+lockers is the number of lockers that can simultaneously request locks
+in the system.  The maximum number of lock objects is the number of
+objects that can simultaneously be locked in the system.  Selecting
+appropriate values requires an understanding of your application and
+its databases.  If the values are too small, then requests for locks in
+an application will fail.  If the values are too large, then the locking
+subsystem will consume more resources than is necessary.  It is better
+to err in the direction of allocating too many locks, lockers and
+objects as increasing the number of locks does not require large amounts
+of additional resources.
+<p>The recommended algorithm for selecting the maximum number of locks,
+lockers and lock objects, is to run the application under stressful
+conditions and then review the lock system's statistics to determine
+the maximum number of locks, lockers and lock objects that were used.
+Then, double these values for safety.  However, in some large
+applications, finer granularity of control is necessary in order to
+minimize the size of the lock subsystem.
+<p>The maximum number of lockers can be estimated as follows:
+<ul type=disc>
+<li>If the
+database environment is configured to use transactions, then the maximum
+number of lockers needed is the number of simultaneously active
+transactions and child transactions (where a child transaction is active
+until its parent commits or aborts, not until it commits or aborts).
+<li>If the database environment is not configured to use transactions, then
+the maximum number of lockers needed is the number of simultaneous
+non-cursor operations plus an additional locker for every simultaneously
+open cursor.
+</ul>
+<p>The maximum number of lock objects needed can be estimated as follows:
+<ul type=disc>
+<li>For Btree and Recno access methods, you will need, at a minimum, one
+lock object per level of the database tree.  (Unless keys are quite
+large with respect to the page size, neither Recno nor Btree database
+trees should ever be deeper than five levels.)  Then, you will need one
+lock object for each leaf page of the database tree that will be
+simultaneously accessed.
+<li>For the Queue access method you will need one lock object per record
+that is simultaneously accessed.  To this, add one lock object per page
+that will be simultaneously accessed.  (Since the Queue access method
+uses fixed-length records, and the database page size is known, it is
+possible to calculate the number of pages and therefore, lock objects,
+required.)  Deleted records skipped by a <a href="../../api_c/dbc_get.html#DB_NEXT">DB_NEXT</a> or
+<a href="../../api_c/dbc_get.html#DB_PREV">DB_PREV</a> operation do not require a separate lock object.
+Further, if your application is using transactions, then no database
+operation will ever use more than three lock objects at any time.
+<li>For the Hash access method you only need a single lock object.
+</ul>
+<p>For all access methods, you should then add an additional lock object
+per database, for the database's metadata page.
+<p>The maximum number of locks required by an application cannot be easily
+estimated.  It is possible to calculate a maximum number of locks by
+multiplying the maximum number of lockers, times the maximum number of
+lock objects, times two (two for the two possible lock modes for each
+object, read and write).  However, this is a pessimal value, and real
+applications are unlikely to actually need that many locks.  Review of
+the lock subsystem statistics is the best way to determine this value.

+<h1 align=center>Locking and non-Berkeley DB applications</h1>
+<p>The locking subsystem is useful outside the context of Berkeley DB.  It can be
+used to manage concurrent access to any collection of either ephemeral or
+persistent objects.  That is, the lock region can persist across
+invocations of an application, so it can be used to provide long-term
+locking (e.g., conference room scheduling).
+<p>In order to use the locking subsystem in such a general way, the
+applications must adhere to a convention for naming objects and lockers.
+Consider the conference room scheduling problem described above.  Assume
+there are three conference rooms and that we wish to schedule them in
+half-hour intervals.
+<p>The scheduling application must then select a way to identify each
+conference room/time slot combination.  In this case, we could describe
+the objects being locker as bytestrings consisting of the conference room
+name, the date on which it is needed, and the beginning of the appropriate
+half-hour slot.
+<p>Lockers are 32-bit numbers, so we might choose to use the User ID of the
+individual running the scheduling program.  To schedule half-hour slots,
+all the application need do is issue a <a href="../../api_c/lock_get.html">lock_get</a> call for the
+appropriate locker/object pair.  To schedule a longer slot, the
+application would issue a <a href="../../api_c/lock_vec.html">lock_vec</a> call with one <a href="../../api_c/lock_get.html">lock_get</a>
+operation per half-hour up to the total length.  If the <a href="../../api_c/lock_vec.html">lock_vec</a>
+call fails, the application would have to release the parts of the time
+slot that were obtained.
+<p>To cancel a reservation, the application would make the appropriate
+<a href="../../api_c/lock_put.html">lock_put</a> calls.  To reschedule a reservation, the <a href="../../api_c/lock_get.html">lock_get</a>
+and <a href="../../api_c/lock_put.html">lock_put</a> calls could all be made inside of a single
+<a href="../../api_c/lock_vec.html">lock_vec</a> call.  The output of <a href="../../api_c/lock_stat.html">lock_stat</a> could be
+post-processed into a human-readable schedule of conference room use.

+<h1 align=center>Locking without transactions</h1>
+<p>If an application runs with locking specified, but not transactions (e.g.,
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> is called with <a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a> or
+<a href="../../api_c/env_open.html#DB_INIT_CDB">DB_INIT_CDB</a> specified, but not <a href="../../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a>), locks are
+normally acquired during each Berkeley DB operation and released before the
+operation returns to the caller.  The only exception is in the case of
+cursor operations.  As cursors identify a particular position in a file,
+a cursor must retain a read-lock across cursor calls to make sure that
+that position is uniquely identifiable during the next cursor call,
+because an operation using <a href="../../api_c/dbc_get.html#DB_CURRENT">DB_CURRENT</a> must reference the same
+record as the previous cursor call.  Such cursor locks cannot be released
+until either the cursor is reset using the <a href="../../api_c/db_get.html#DB_GET_BOTH">DB_GET_BOTH</a>,
+<a href="../../api_c/dbc_get.html#DB_SET">DB_SET</a>, <a href="../../api_c/dbc_get.html#DB_SET_RANGE">DB_SET_RANGE</a>, <a href="../../api_c/dbc_put.html#DB_KEYFIRST">DB_KEYFIRST</a>, or
+<a href="../../api_c/dbc_put.html#DB_KEYLAST">DB_KEYLAST</a> functionality, in which case a new cursor lock is
+established, or the cursor is closed.  As a result, application designers
+are encouraged to close cursors as soon as possible.
+<p>It is important to realize that concurrent applications that use locking
+must ensure that two concurrent threads do not interfere with each other.
+However, as Btree and Hash access method page splits can occur at any
+time, there is virtually no way to guarantee that an application which
+writes the database cannot deadlock.  Applications running without the
+protection of transactions may deadlock, and when they do so, can leave
+the database in an inconsistent state.  Applications that need concurrent
+access, but not transactions, are more safely implemented using the Berkeley DB Concurrent Data Store
+Product.

+<h1 align=center>Page locks</h1>
+<p>Under normal operation, the access methods use page locking.  The pagesize
+of a database is set when the database is created and may be specified by
+calling the <a href="../../api_c/db_set_pagesize.html">DB-&gt;set_pagesize</a> function.  If not specified, the Berkeley DB
+package tries to select a pagesize that will provide the best I/O
+performance by setting the page size equal to the block size of the
+underlying file system.
+<p>In the Btree access method, Berkeley DB uses a technique called lock coupling
+to improve concurrency.  The traversal of a Btree requires reading a page,
+searching that page to determine which page to search next and then
+repeating this process on the next page.  Once a page has been searched,
+it will never be accessed again for this operation, unless a page split
+is required.  To improve concurrency in the tree, once the next page to
+read/search has been determined, that page is locked, and then atomically
+(i.e., without relinquishing control of the lock manager) the original
+page lock is released.
+<p>As the Recno access method is built upon Btree, it too uses lock coupling
+for read operations.  However, as the Recno access method must maintain
+a count of records on its internal pages, it cannot lock couple during
+write operations.  Instead, it retains write locks on all internal pages
+during every update operation.  For this reason, it is not possible to
+have high concurrency in the Recno access method in the presence of write
+operations.
+<p>The Queue access method only uses short term page locks.  That is, a page
+lock is released prior to requesting another page lock.  Record locks are
+used for transaction isolation.  The provides a high degree of concurrency
+for write operations.  A metadata page is used to keep track of the head
+and tail of the queue.  This page is never locked during other locking or
+I/O operations.
+<p>The Hash access method does not have such traversal issues, but because
+it implements dynamic hashing, it must always refer to its metadata while
+computing a hash function.  This metadata is stored on a special page in
+the hash database.  This page must therefore be read locked on every
+operation.  Fortunately, it need only be write locked when new pages are
+allocated to the file, which happens in three cases: 1) a hash bucket
+becomes full and needs to split, 2) a key or data item is too large to
+fit on a normal page, and 3) the number of duplicate items for a fixed
+key becomes sufficiently large that they are moved to an auxiliary page.
+In this case, the access method must obtain a write lock on the metadata
+page, thus requiring that all readers be blocked from entering the tree
+until the update completes.

+<h1 align=center>Standard lock modes</h1>
+<p>The Berkeley DB locking protocol is described by a conflict matrix.  A conflict
+matrix is an n x n array where n is the number of different lock modes
+supported, and the (i, j)th entry of the array indicates whether a lock of
+mode i conflicts with a lock of mode j.
+<p>The Berkeley DB include files declare two commonly used conflict arrays:
+<p><dl compact>
+<p><dt>const u_int8_t db_rw_conflicts[ ];<dd>This is a conflict matrix for a simple scheme using shared and exclusive
+lock modes.
+<p><dt>const u_int8_t db_riw_conflicts[ ];<dd>This is a conflict matrix that involves various intent lock modes (e.g.,
+intent shared) that are used for multigranularity locking.
+</dl>
+<p>The number of modes associated with each matrix are DB_LOCK_RW_N and
+DB_LOCK_RIW_N, respectively.
+<p>In addition, the Berkeley DB include file defines the type <b>db_lockmode_t</b>,
+which is the type of the lock modes used with the standard tables above:
+<p><dl compact>
+<p><dt>DB_LOCK_NG<dd>not granted (always 0)
+<p><dt>DB_LOCK_READ<dd>read (shared)
+<p><dt>DB_LOCK_WRITE<dd>write (exclusive)
+</dl>
+<p>As an example, consider the basic multiple-reader/single writer conflict
+matrix described by <b>db_rw_conflicts</b>.  In the following
+example (and in the appropriate file), a 1 represents a conflict (i.e.,
+do not grant the lock if the indicated lock is held) and a 0 indicates
+that it is OK to grant the lock.
+<p>The rows indicate the lock that is held and the columns indicate the lock
+that is requested.
+<p><blockquote><pre>		Notheld	Read    Write
+Notheld		0	0	0
+Read*		0	0	1
+Write**		0	1	1
+</pre></blockquote>
+<p><dl compact>
+<p><dt>*<dd>In this case, suppose that there is a read lock held on an object.  A new
+request for a read lock would be granted, but a request for a write lock
+would not.
+<p><dt>**<dd>In this case, suppose that there is a write lock held on an object.  A
+new request for either a read or write lock would be denied.

+<h1 align=center>Locking with transactions: two-phase locking</h1>
+<p>Berkeley DB uses a locking protocol called two-phase locking.  This is the
+traditional protocol used in conjunction with lock-based transaction
+systems.
+<p>In a two-phase locking (2PL) system, transactions are broken up into two
+distinct phases.  During the first phase, the transaction only acquires
+locks.  During the second phase, the transaction only releases locks.
+More formally, once a transaction releases a lock, it may not acquire any
+additional locks.  Practically, this translates into a system where locks
+are acquired as they are needed throughout a transaction and retained
+until the transaction ends, either by committing or aborting.  In Berkeley DB,
+locks are released during <a href="../../api_c/txn_abort.html">txn_abort</a> or <a href="../../api_c/txn_commit.html">txn_commit</a>.  The
+only exception to this protocol occurs when we use lock-coupling to
+traverse a data structure.  If the locks are held only for traversal
+purposes, then the locks may be released before transaction commit or
+abort.
+<p>For applications, the implications of 2PL are that long-running
+transactions will hold locks for a long time.  When designing
+applications, lock contention should be considered.  In order to reduce
+the probability of deadlock and achieve the best level of concurrency
+possible, the following guidelines are helpful.
+<p><ol>
+<p><li>When accessing multiple databases, design all transactions so
+that they access the files in the same order.
+<p><li>If possible, access your most hotly contested resources last
+(so that their locks are held for the shortest time possible).
+<p><li>If possible, use nested transactions to protect the parts of
+your transaction most likely to deadlock.

+However, setting the log file size too low can potentially cause
+problems as it would be possible to run out of log sequence numbers,

+written to disk.  Larger buffer sizes can significantly increase
+throughput in the presence of long running transactions, highly
+concurrent applications, or transactions producing large amounts of
+data.  By default, the buffer is 32KB.

+<h1 align=center>Berkeley DB and logging</h1>
+<p>The logging subsystem is the logging facility used by Berkeley DB.  It is
+largely Berkeley DB specific, although it is potentially useful outside of
+the Berkeley DB package for applications wanting write-ahead logging support.
+Applications wanting to use the log for purposes other than logging file
+modifications based on a set of open file descriptors will almost
+certainly need to make source code modifications to the Berkeley DB code
+base.
+<p>A log can be shared by any number of threads of control.  The
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> interface is used to open a log.  When the log is no
+longer in use, it should be closed, using the <a href="../../api_c/env_close.html">DBENV-&gt;close</a>
+interface.
+<p>Individual log entries are identified by log sequence numbers.  Log
+sequence numbers are stored in an opaque object, a <a href="../../api_c/db_lsn.html">DB_LSN</a>.
+<p>The <a href="../../api_c/log_put.html">log_put</a> interface is used to append new log records to the
+log.  Optionally, the <a href="../../api_c/log_put.html#DB_CHECKPOINT">DB_CHECKPOINT</a> flag can be used to output
+a checkpoint log record (indicating that the log is consistent to that
+point and recoverable after a system or application failure), as well
+as open-file information.  The <a href="../../api_c/log_get.html">log_get</a> interface is used to
+retrieve log records from the log.
+<p>There are additional interfaces for integrating the log subsystem with a
+transaction processing system:
+<p><dl compact>
+<p><dt><a href="../../api_c/log_register.html">log_register</a> and <a href="../../api_c/log_unregister.html">log_unregister</a><dd>These interfaces associate files with identification numbers.  These
+identification numbers are logged so that transactional recovery

+<h1 align=center>Log file limits</h1>
+<p>Log file names and sizes impose a limit on how long databases may be
+used in a Berkeley DB database environment.  It is quite unlikely that an
+application will reach this limit, however, if the limit is reached,
+the Berkeley DB environment's databases must be dumped and reloaded.
+<p>The log file name consists of <b>log.</b> followed by 10 digits, with
+a maximum of 2,000,000,000 log files.  Consider an application performing
+6000 transactions per second, for 24 hours a day, logged into 10MB log
+files, where each transaction is logging approximately 500 bytes of data.
+The calculation:
+<p><blockquote><pre>(10 * 2^20 * 2000000000) / (6000 * 500 * 365 * 60 * 60 * 24) = ~221</pre></blockquote>
+<p>indicates that the system will run out of log file names in roughly 221
+years.
+<p>There is no way to reset the log file name space in Berkeley DB.  If your
+application is reaching the end of its log file name space, you must:
+<p><ol>
+<p><li>Archive your databases as if to prepare for catastrophic failure (see
+<a href="../../utility/db_archive.html">db_archive</a> for more information).
+<p><li>Dump and re-load all your databases (see <a href="../../utility/db_dump.html">db_dump</a> and
+<a href="../../utility/db_load.html">db_load</a> for more information).
+<p><li>Remove all of the log files from the database environment.  Note, this
+is the only situation where all of the log files are removed from an
+environment, in all other cases at least a single log file is
+retained.
+<p><li>Restart your application.

+<p>
+<h1 align=center>Configuring the memory pool</h1>
+<p>There are two interfaces used for configuring the memory pool.
+<p>The most important tuning parameter for almost all applications, including
+Berkeley DB applications, is the size of the pool.  There are two ways to
+specify the pool size.  First, calling the <a href="../../api_c/env_set_cachesize.html">DBENV-&gt;set_cachesize</a> function
+specifies the pool size for all of the applications sharing the Berkeley DB
+environment.  Second, by calling the <a href="../../api_c/db_set_cachesize.html">DB-&gt;set_cachesize</a> function.  The
+latter only specifies a pool size for the specific database.  Note, it is
+meaningless to call <a href="../../api_c/db_set_cachesize.html">DB-&gt;set_cachesize</a> for a database opened inside
+of a Berkeley DB environment, since the environment pool size will override any
+pool size specified for a single database.  For information on tuning the
+Berkeley DB cache size, see <a href="../../ref/am_conf/cachesize.html">Selecting
+a cache size</a>.
+<p>The second memory pool configuration interface specifies the maximum size
+of backing files to map into the process address space instead of copying
+pages through the local cache.  Only read-only database files can be
+mapped into process memory.  Because of the requirements of the Berkeley DB
+transactional implementation, log records describing database changes must
+be written to disk before the actual database changes.  As mapping
+read-write database files into process memory would permit the underlying
+operating system to write modified database changes at will, it is not
+supported.
+<p>Mapping files into the process address space can result in
+better-than-usual performance, as available virtual memory is normally
+much larger than the local cache, and page faults are faster than page
+copying on many systems.  However, in the presence of limited virtual
+memory it can cause resource starvation, and in the presence of large
+databases, it can result in immense process sizes.
+<p>To specify that no files are to be mapped into the process address space,
+specify the <a href="../../api_c/env_open.html#DB_NOMMAP">DB_NOMMAP</a> flag to the <a href="../../api_c/env_set_flags.html">DBENV-&gt;set_flags</a> interface.
+To specify that any individual file should not be mapped into the process
+address space, specify the <a href="../../api_c/env_open.html#DB_NOMMAP">DB_NOMMAP</a> flag to the
+<a href="../../api_c/memp_fopen.html">memp_fopen</a> interface.  To limit the size of files mapped into the
+process address space, use the <a href="../../api_c/env_set_mp_mmapsize.html">DBENV-&gt;set_mp_mmapsize</a> function.

+<h1 align=center>Berkeley DB and the memory pool</h1>
+<p>The memory pool subsystem is the general-purpose shared memory buffer pool
+used by Berkeley DB.  This module is useful outside of the Berkeley DB package for
+processes that require page-oriented, cached, shared file access.
+<p>A memory pool is a shared memory cache shared by any number of processes
+and threads within processes.  The <a href="../../api_c/env_open.html">DBENV-&gt;open</a> interface opens, and
+optionally creates, a memory pool.  When that pool is no longer in use,
+it should be closed, using the <a href="../../api_c/env_close.html">DBENV-&gt;close</a> interface.
+<p>The <a href="../../api_c/memp_fopen.html">memp_fopen</a> interface opens an underlying file within the
+memory pool.  When that file is no longer in use, it should be closed,
+using the <a href="../../api_c/memp_fclose.html">memp_fclose</a> interface.  The <a href="../../api_c/memp_fget.html">memp_fget</a> interface
+is used to retrieve pages from files in the pool.  All retrieved pages
+must be subsequently returned using the <a href="../../api_c/memp_fput.html">memp_fput</a> interface.  At
+the time that pages are returned, they may be marked <b>dirty</b>, which
+causes them to be written to the backing disk file before being discarded
+from the pool.  If there is insufficient room to bring a new page in the
+pool, a page is selected to be discarded from the pool.  If that page is
+dirty, it is first written to the backing file.  The page is selected
+using a somewhat modified least-recently-used algorithm.  Pages in files
+may also be explicitly marked clean or dirty using the <a href="../../api_c/memp_fset.html">memp_fset</a>
+interface.  All dirty pages in the pool from any underlying file may also
+be flushed as a group using the <a href="../../api_c/memp_fsync.html">memp_fsync</a> interface.
+<p>There are additional interfaces for manipulating the entire memory pool:
+<ul type=disc>
+<li>It is possible to gradually flush buffers from the pool in order to
+maintain a consistent percentage of clean buffers in the pool using the
+<a href="../../api_c/memp_trickle.html">memp_trickle</a> interface.
+<li>The <a href="../../utility/db_stat.html">db_stat</a> utility uses the <a href="../../api_c/memp_stat.html">memp_stat</a> interface to
+display statistics about the efficiency of the pool.
+<li>As some conversion may be necessary when pages are read or written the
+<a href="../../api_c/memp_register.html">memp_register</a> function allows applications to specify automatic
+input and output processing in these cases.
+<li>There is one additional interface that is intended for manipulating the
+memory pool, but which is specific to database systems.  The
+<a href="../../api_c/memp_sync.html">memp_sync</a> interface flushes dirty pages from all files held in
+the pool up to a specified database log sequence number.
+<li>Finally, the entire pool may be discarded using the <a href="../../api_c/env_remove.html">DBENV-&gt;remove</a>
+interface.

+<h1 align=center>Using Berkeley DB with Perl</h1>
+<p>The original Perl module for Berkeley DB was DB_File, which was written to
+interface to Berkeley DB version 1.85.  The newer Perl module for Berkeley DB is
+BerkeleyDB, which was written to interface to version 2.0 and subsequent
+releases.  Because Berkeley DB version 2.X has a compatibility API for version
+1.85, you can (and should!) build DB_File using version 2.X of Berkeley DB,
+although DB_File will still only support the 1.85 functionality.
+<p>DB_File is distributed with the standard Perl source distribution (look
+in the directory "ext/DB_File").  You can find both DB_File and BerkeleyDB
+on CPAN, the Comprehensive Perl Archive Network of mirrored FTP sites.
+The master CPAN site is
+<a href="ftp://ftp.funet.fi/">ftp://ftp.funet.fi/</a>.
+<p>Versions of both BerkeleyDB and DB_File that are known to work correctly
+with each release of Berkeley DB are included in the distributed Berkeley DB source
+tree, in the subdirectories <b>perl.BerkeleyDB</b> and
+<b>perl.DB_File</b>.  Each of those directories contains a
+<b>README</b> file with instructions on installing and using those
+modules.
+<p>The Perl interface is not maintained by Sleepycat Software.  Questions
+about the DB_File and BerkeleyDB modules are best asked on the Usenet
+newsgroup comp.lang.perl.modules.

+<h1 align=center>Application signal handling</h1>
+<p>When applications using Berkeley DB receive signals, it is important that they
+exit gracefully, discarding any Berkeley DB locks that they may hold.  This is
+normally done by setting a flag when a signal arrives, and then checking
+for that flag periodically within the application.  As Berkeley DB is not
+reentrant, the signal handler should not attempt to release locks and/or
+close the database handles itself.  Reentering Berkeley DB is not guaranteed to
+work correctly and the results are undefined.
+<p>If an application exits holding a lock, the situation is no different
+than if the application crashed, and all applications participating in
+the database environment must be shutdown, and then recovery must be
+performed.  If this is not done,  databases may be left in an
+inconsistent state or locks the application held may cause unresolvable
+deadlocks inside the environment, causing applications to hang.

+<h1 align=center>Copying databases</h1>
+<p>Because file identification cookies (e.g., file names, device and inode
+numbers, volume and file IDs, etc.) are not necessarily unique or
+maintained across system reboots, each Berkeley DB database file contains a
+20-byte file identification bytestring that is stored in the first page
+of the database at a page byte offset of 36 bytes.  When multiple
+processes or threads open the same database file in Berkeley DB, it is this
+bytestring that is used to ensure that the same underlying pages are
+updated in the shared memory buffer pool no matter which Berkeley DB handle is
+used for the operation.
+<p>It is usually a bad idea to physically copy a database to a new name.  In
+the few cases where copying is the best solution for your application,
+you must guarantee there are never two different databases with the same
+file identification bytestring in the memory pool at the same time.
+Copying databases is further complicated by the fact that the shared
+memory buffer pool does not discard all cached copies of pages for a
+database when the database is logically closed, that is, when
+<a href="../../api_c/db_close.html">DB-&gt;close</a> is called.  Nor is there a Berkeley DB interface to explicitly
+discard pages from the shared memory buffer pool for any particular
+database.
+<p>Before copying a database, you must ensure that all modified pages have
+been written from the memory pool cache to the backing database file.
+This is done using the <a href="../../api_c/db_sync.html">DB-&gt;sync</a> or <a href="../../api_c/db_close.html">DB-&gt;close</a> interfaces.
+<p>Before using a copy of a database from Berkeley DB, you must ensure that all
+pages from any database with the same bytestring have been removed from
+the memory pool cache.  If the environment in which you intend to open
+the copy of the database potentially has pages from files with identical
+bytestrings to the copied database (which is likely to be the case), there
+are a few possible solutions:
+<p><ol>
+<p><li>Remove the environment, either explicitly or by calling <a href="../../api_c/env_remove.html">DBENV-&gt;remove</a>.
+Note, this will not allow you to access both the original and copy of the
+database at the same time.
+<p><li>Overwrite the bytestring in the copied database with a new bytestring.
+This allows you to access both the original and copy of the database at
+the same time.
+<p><li>Create a new file that will have a new bytestring.  The simplest
+way to create a new file that will have a new bytestring is to call the
+<a href="../../utility/db_dump.html">db_dump</a> utility to dump out the contents of the database, and then
+use the <a href="../../utility/db_load.html">db_load</a> utility to load the dumped output into a new file
+name.  This allows you to access both the original and copy of the
+database at the same time.

+<h1 align=center>Database limits</h1>
+<p>The largest database file that Berkeley DB can handle depends on the page size
+selected by the application.  Berkeley DB stores database file page numbers as
+unsigned 32-bit numbers and database file page sizes as unsigned 16-bit
+numbers.  Using the maximum database page size of 65536, this results in
+a maximum database file size of 2<sup>48</sup> (256 terabytes).  The
+minimum database page size is 512 bytes, which results in a minimum
+maximum database size of 2<sup>41</sup> (2 terabytes).
+<p>The largest database file Berkeley DB can support is potentially further limited
+if the host system does not have filesystem support for files larger than
+2<sup>32</sup>, including the ability to seek to absolute offsets within
+those files.
+<p>The largest key or data item that Berkeley DB can support is largely limited
+by available memory.  Specifically, while key and data byte strings may
+be of essentially unlimited length, any one of them must fit into
+available memory so that it can be returned to the application.  As some
+of the Berkeley DB interfaces return both key and data items to the application,
+those interfaces will require that any key/data pair fit simultaneously
+into memory.  Further, as the access methods may need to compare key and
+data items with other key and data items, it may be a requirement that
+any two key or two data items fit into available memory.  Finally, when
+writing applications supporting transactions, it may be necessary to have
+an additional copy of any data item in memory for logging purposes.
+<p>The maximum Btree depth is 255.

+<h1 align=center>Disk space requirements</h1>
+<p>It is possible to estimate the total database size based on the size of
+the data.  Simply put, the following calculations attempt to figure out
+how many bytes you will need to hold a set of data and then how many pages
+it will take to actually store it on disk.
+<p>Space freed by deleting key/data pairs from a Btree or Hash database is
+never returned to the filesystem, although it is reused where possible.
+This means that the Btree and Hash databases are grow-only.  If enough
+keys are deleted from a database that shrinking the underlying file is
+desirable, you should create a new database and insert the records from
+the old one into it.
+<p>These are rough estimates at best. For example, they do not take into
+account overflow records, filesystem metadata information, or real-life
+situations where the sizes of key and data items are wildly variable, and
+the page-fill factor changes over time.
+<h3>Btree</h3>
+<p>The formulas for the Btree access method are as follows:
+<p><blockquote><pre>useful-bytes-per-page = (page-size - page-overhead) * page-fill-factor
+<p>
+bytes-of-data = n-records *
+    (bytes-per-entry + page-overhead-for-two-entries)
+<p>
+n-pages-of-data = bytes-of-data / bytes-per-page
+<p>
+total-pages-on-disk = n-pages-of-data * page-size
+</pre></blockquote>
+<p>The <b>useful-bytes-per-page</b> is a measure of the bytes on each page
+that will actually hold the application data.  It is computed as the total
+number of bytes on the page that are available to hold application data,
+corrected by the percentage of the page that is likely to contain data.
+The reason for this correction is that the percentage of a page that
+contains application data can vary from close to 50% after a page split,
+to almost 100% if the entries in the database were inserted in sorted
+order.  Obviously, the <b>page-fill-factor</b> can drastically alter
+the amount of disk space required to hold any particular data set.  The
+page-fill factor of any existing database can be displayed using the
+<a href="../../utility/db_stat.html">db_stat</a> utility.
+<p>As an example, using an 8K page size, with an 85% page-fill factor, there
+are 6941 bytes of useful space on each page:
+<p><blockquote><pre>6941 = (8192 - 26) * .85</pre></blockquote>
+<p>The total <b>bytes-of-data</b> is an easy calculation: it is the number
+of key/data pairs plus the overhead required to store each pair on a page.
+The overhead to store a single item on a Btree page is 5 bytes.  So,
+assuming 60,000,000 key/data pairs, each of which is 8 bytes long, there
+are 1440000000 bytes, or roughly 1.34GB, of total data:
+<p><blockquote><pre>1560000000 = 60000000 * ((8 * 2) + (5 * 2))</pre></blockquote>
+<p>The total pages of data, <b>n-pages-of-data</b>, is the
+<b>bytes-of-data</b> divided by the <b>useful-bytes-per-page</b>.  In
+the example, there are 224751 pages of data.
+<p><blockquote><pre>224751 = 1560000000 / 6941</pre></blockquote>
+<p>The total bytes of disk space for the database is <b>n-pages-of-data</b>
+multiplied by the <b>page-size</b>.  In the example, the result is
+1841160192 bytes, or roughly 1.71GB.
+<p><blockquote><pre>1841160192 = 224751 * 8192</pre></blockquote>
+<h3>Hash</h3>
+<p>The formulas for the Hash access method are as follows:
+<p><blockquote><pre>useful-bytes-per-page = (page-size - page-overhead)
+<p>
+bytes-of-data = n-records *
+    (bytes-per-entry + page-overhead-for-two-entries)
+<p>
+n-pages-of-data = bytes-of-data / bytes-per-page
+<p>
+total-pages-on-disk = n-pages-of-data * page-size
+</pre></blockquote>
+<p>The <b>useful-bytes-per-page</b> is a measure of the bytes on each page
+that will actually hold the application data.  It is computed as the total
+number of bytes on the page that are available to hold application data.
+If the application has explicitly set a page fill factor, then pages will
+not necessarily be kept full.  For databases with a preset fill factor,
+see the calculation below.  The page-overhead for Hash databases is 26
+bytes and the page-overhead-for-two-entries is 6 bytes.
+<p>As an example, using an 8K page size, there are 8166 bytes of useful space
+on each page:
+<p><blockquote><pre>8166 = (8192 - 26)</pre></blockquote>
+<p>The total <b>bytes-of-data</b> is an easy calculation: it is the number
+of key/data pairs plus the overhead required to store each pair on a page.
+In this case that's 6 bytes per pair.  So, assuming 60,000,000 key/data
+pairs, each of which is 8 bytes long, there are 1320000000 bytes, or
+roughly 1.23GB, of total data:
+<p><blockquote><pre>1320000000 = 60000000 * ((16 + 6))</pre></blockquote>
+<p>The total pages of data, <b>n-pages-of-data</b>, is the
+<b>bytes-of-data</b> divided by the <b>useful-bytes-per-page</b>.  In
+this example, there are 161646 pages of data.
+<p><blockquote><pre>161646 = 1320000000 / 8166</pre></blockquote>
+<p>The total bytes of disk space for the database is <b>n-pages-of-data</b>
+multiplied by the <b>page-size</b>.  In the example, the result is
+1324204032 bytes, or roughly 1.23GB.
+<p><blockquote><pre>1324204032 = 161646 * 8192</pre></blockquote>
+<p>Now, let's assume that the application specified a fill factor explicitly.
+The fill factor indicates the target number of items to place on a single
+page (a fill factor might reduce the utilization of each page, but it can
+be useful in avoiding splits and preventing buckets from becoming too
+large.  Using our estimates above, each item is 22 bytes (16 + 6) and
+there are 8166 useful bytes on a page (8192 - 26).  That means that, on
+average, you can fit 371 pairs per page.
+<p><blockquote><pre>371 = 8166 / 22</pre></blockquote>
+<p>However, let's assume that the application designer knows that while most
+items are 8 bytes, they can sometimes be as large as 10 and it's very
+important to avoid overflowing buckets and splitting.  Then, the
+application might specify a fill factor of 314.
+<p><blockquote><pre>314 = 8166 / 26</pre></blockquote>
+<p>With a fill factor of 314, then the formula for computing database size
+is:
+<p><blockquote><pre>npages = npairs / pairs-per-page</pre></blockquote>
+<p>or 191082.
+<p><blockquote><pre>191082 = 60000000 / 314</pre></blockquote>
+<p>At 191082 pages, the total database size would be 1565343744 or 1.46GB.
+<p><blockquote><pre>1565343744 = 191082 * 8192 </pre></blockquote>
+<p>There are a few additional caveats with respect to Hash databases.  This
+discussion assumes that the hash function does a good job of evenly
+distributing keys among hash buckets.  If the function does not do this,
+you may find your table growing significantly larger than you expected.
+Secondly, in order to provide support for Hash databases co-existing with
+other databases in a single file, pages within a Hash database are
+allocated in power-of-2 chunks.  That means that a Hash database with 65
+buckets will take up as much space as a Hash database with 128 buckets;
+each time the Hash database grows beyond its current power-of-two number
+of buckets, it allocates space for the next power-of-two buckets.  This
+space may be sparsely allocated in the file system, but the files will
+appear to be their full size.  Finally, because of this need for
+contiguous allocation, overflow pages and duplicate pages can be allocated
+only at specific points in the file, and this too can lead to sparse hash
+tables.

+<h1 align=center>Error returns to applications</h1>
+<p>Except for the historic <a href="../../api_c/dbm.html">dbm</a>, <a href="../../api_c/dbm.html">ndbm</a> and <a href="../../api_c/hsearch.html">hsearch</a>
+interfaces, Berkeley DB does not use the global variable <b>errno</b> to
+return error values.  The return values for all Berkeley DB functions are
+grouped into three categories:
+<p><dl compact>
+<p><dt>0<dd>A return value of 0 indicates that the operation was successful.
+<p><dt>&gt; 0<dd>A return value that is greater than 0 indicates that there was a system
+error.  The <b>errno</b> value returned by the system is returned by
+the function, e.g., when a Berkeley DB function is unable to allocate memory,
+the return value from the function will be ENOMEM.
+<p><dt>&lt; 0<dd>A return value that is less than 0 indicates a condition that was not
+a system failure, but was not an unqualified success, either.  For
+example, a routine to retrieve a key/data pair from the database may
+return DB_NOTFOUND when the key/data pair does not appear in
+the database, as opposed to the value of 0, which would be returned if
+the key/data pair were found in the database.
+<p>        <a name="3"><!--meow--></a>    
+All values returned by Berkeley DB functions are less than 0 in order to avoid
+conflict with possible values of <b>errno</b>.  Specifically, Berkeley DB
+reserves all values from -30,800 to -30,999 to itself as possible error
+values.  There are a few Berkeley DB interfaces where it is possible for an
+application function to be called by a Berkeley DB function and subsequently
+fail with an application-specific return.  Such failure returns will be
+passed back to the function that originally called a Berkeley DB interface.
+To avoid ambiguity as to the cause of the error, error values separate
+from the Berkeley DB error name space should be used.
+</dl>
+While possible error returns are specified by each individual function's
+manual page, there are a few error returns that deserve special mention:
+<h3><a name="DB_NOTFOUND">DB_NOTFOUND</a> and <a name="DB_KEYEMPTY">DB_KEYEMPTY</a></h3>
+<p>There are two special return values that are similar in meaning, and that
+are returned in similar situations, and therefore might be confused:
+DB_NOTFOUND and DB_KEYEMPTY.
+<p>The DB_NOTFOUND error return indicates that the requested key/data
+pair did not exist in the database or that start- or end-of-file has been
+reached.
+<p>The DB_KEYEMPTY error return indicates that the requested key/data
+pair logically exists but was never explicitly created by the application
+(the Recno and Queue access methods will automatically create key/data
+pairs under some circumstances; see <a href="../../api_c/db_open.html">DB-&gt;open</a> for more
+information), or that the requested key/data pair was deleted and never
+re-created.  In addition, the Queue access method will return
+DB_KEYEMPTY for records which were created as part of a
+transaction which was later aborted, and never re-created.
+<h3><a name="DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a></h3>
+<p>When multiple threads of control are modifying the database, there is
+normally the potential for deadlock. In Berkeley DB, deadlock is signified by
+an error return from the Berkeley DB function of the value
+DB_LOCK_DEADLOCK.  Whenever a Berkeley DB function returns
+DB_LOCK_DEADLOCK, the enclosing transaction should be aborted.
+<p>Any Berkeley DB function that attempts to acquire locks can potentially return
+DB_LOCK_DEADLOCK.  Practically speaking, the safest way to deal
+with applications that can deadlock is to handle an
+DB_LOCK_DEADLOCK return from any Berkeley DB access method call.
+<h3><a name="DB_LOCK_NOTGRANTED">DB_LOCK_NOTGRANTED</a></h3>
+<p>When multiple threads of control are modifying the database, there is
+normally the potential for deadlock.  In order to avoid deadlock,
+applications may specify, on a per-transaction basis, that if a lock is
+unavailable, the Berkeley DB operation should return immediately instead of
+waiting on the lock.  The error return in this case will be
+DB_LOCK_NOTGRANTED.  Whenever a Berkeley DB function returns
+DB_LOCK_NOTGRANTED, the enclosing transaction should be aborted.
+<h3><a name="DB_RUNRECOVERY">DB_RUNRECOVERY</a></h3>
+<p>There exists a class of errors that Berkeley DB considers fatal to an entire
+Berkeley DB environment.  An example of this type of error is a corrupted
+database, or a log write failure because the disk is out of free space.
+The only way to recover from these failures is to have all threads of
+control exit the Berkeley DB environment, run recovery of the environment, and
+re-enter Berkeley DB. (It is not strictly necessary that the processes exit,
+although that is the only way to recover system resources, such as file
+descriptors and memory, allocated by Berkeley DB.)
+<p>When this type of error is encountered, the error value
+DB_RUNRECOVERY is returned. This error can be returned by any
+Berkeley DB interface.  Once DB_RUNRECOVERY is returned by any
+interface, it will be returned from all subsequent Berkeley DB calls made by
+any threads or processes participating in the environment.
+<p>Optionally, applications may also specify a fatal-error callback function
+using the <a href="../../api_c/env_set_paniccall.html">DBENV-&gt;set_paniccall</a> function.  This callback function will be
+called with two arguments: a reference to the DB_ENV structure associated
+with the environment, and the <b>errno</b> value associated with the
+underlying error that caused the problem.
+<p>Applications can handle such fatal errors in one of two ways: by checking
+for DB_RUNRECOVERY as part of their normal Berkeley DB error return
+checking, similarly to DB_LOCK_DEADLOCK or any other error, or,
+in applications that have no cleanup processing of their own, by simply
+exiting the application when the callback function is called.

+<p>
+<h1 align=center>Application-specific logging and recovery</h1>
+<p>Berkeley DB includes tools to assist in the development of application-specific
+logging and recovery.  Specifically, given a description of the
+information to be logged, these tools will automatically create logging
+functions (functions that take the values as parameters and construct a
+single record that is written to the log), read functions (functions that
+read a log record and unmarshall the values into a structure that maps
+onto the values you chose to log), a print function (for debugging),
+templates for the recovery functions, and automatic dispatching to your
+recovery functions.
+<h3>Defining Application-Specific Operations</h3>
+<p>Log records are described in files named XXX.src, where "XXX" is a
+unique prefix.  The prefixes currently used in the Berkeley DB package are
+btree, crdel, db, hash, log, qam, and txn.  These files contain interface
+definition language descriptions for each type of log record that
+is supported.
+<p>All lines beginning with a hash character in <b>.src</b> files are
+treated as comments.
+<p>The first non-comment line in the file should begin with the keyword
+PREFIX followed by a string that will be prepended to every function.
+Frequently, the PREFIX is either identical or similar to the name of the
+<b>.src</b> file.
+<p>The rest of the file consists of one or more log record descriptions.
+Each log record description begins with the line:
+<p><blockquote><pre>BEGIN RECORD_NAME RECORD_NUMBER</pre></blockquote>
+<p>and ends with the line:
+<p><blockquote><pre>END</pre></blockquote>
+<p>The RECORD_NAME keyword should be replaced with a unique record name for
+this log record.  Record names must only be unique within <b>.src</b>
+files.
+<p>The RECORD_NUMBER keyword should be replaced with a record number.  Record
+numbers must be unique for an entire application, that is, both
+application-specific and Berkeley DB log records must have unique values.
+Further, as record numbers are stored in log files, which often must be
+portable across application releases, no record number should ever be
+re-used.  The record number space below 10,000 is reserved for Berkeley DB
+itself, applications should choose record number values equal to or
+greater than 10,000.
+<p>Between the BEGIN and END statements, there should be one line for each
+data item that will be logged in this log record.  The format of these
+lines is as follows:
+<p><blockquote><pre>ARG | DBT | POINTER	variable_name	variable_type	printf_format</pre></blockquote>
+<p>The keyword ARG indicates that the argument is a simple parameter of the
+type specified.  The keyword DBT indicates that the argument is a DBT
+containing a length and pointer.  The keyword PTR indicates that the
+argument is a pointer to the data type specified and that the entire type
+should be logged.
+<p>The variable name is the field name within the structure that will be used
+to reference this item.  The variable type is the C type of the variable,
+and the printf format should be "s", for string, "d" for signed integral
+type, or "u" for unsigned integral type.
+<h3>Automatically Generated Functions</h3>
+<p>For each log record description found in the file, the following structure
+declarations and #defines will be created in the file PREFIX_auto.h.
+<p><blockquote><pre><p>
+#define DB_PREFIX_RECORD_TYPE        /* Integer ID number */
+<p>
+typedef struct _PREFIX_RECORD_TYPE_args {
+    /*
+     * These three fields are generated for every record.
+     */
+    u_int32_t type;      /* Record type used for dispatch. */
+<p>
+    /*
+     * Transaction id that identifies the transaction on whose
+     * behalf the record is being logged.
+     */
+    DB_TXN *txnid;
+<p>
+    /*
+     * The LSN returned by the previous call to log for
+     * this transaction.
+     */
+    DB_LSN *prev_lsn;
+<p>
+    /*
+     * The rest of the structure contains one field for each of
+     * the entries in the record statement.
+     */
+};</pre></blockquote>
+<p>The DB_PREFIX_RECORD_TYPE will be described in terms of a value
+DB_PREFIX_BEGIN, which should be specified by the application writer in
+terms of the library provided DB_user_BEGIN macro (this is the value of
+the first identifier available to users outside the access method system).
+<p>In addition to the PREFIX_auto.h file, a file named PREFIX_auto.c is
+created, containing the following functions for each record type:
+<p><dl compact>
+<p><dt>The log function, with the following parameters:<dd><p><dl compact>
+<p><dt>dbenv<dd>The environment handle returned by <a href="../../api_c/env_create.html">db_env_create</a>.
+<p><dt>txnid<dd>The transaction identifier returned by <a href="../../api_c/txn_begin.html">txn_begin</a>.
+<p><dt>lsnp<dd>A pointer to storage for an LSN into which the LSN of the new log record
+will be returned.
+<p><dt>syncflag<dd>A flag indicating if the record must be written synchronously.  Valid
+values are 0 and <a href="../../api_c/log_put.html#DB_FLUSH">DB_FLUSH</a>.
+</dl>
+<p>The log function marshalls the parameters into a buffer and calls
+<a href="../../api_c/log_put.html">log_put</a> on that buffer returning 0 on success and 1 on failure.
+<p><dt>The read function with the following parameters:<dd>
+<p><dl compact>
+<p><dt>recbuf<dd>A buffer.
+<p><dt>argp<dd>A pointer to a structure of the appropriate type.
+</dl>
+<p>The read function takes a buffer and unmarshalls its contents into a
+structure of the appropriate type.  It returns 0 on success and non-zero
+on error.  After the fields of the structure have been used, the pointer
+returned from the read function should be freed.
+<p><dt>The recovery function with the following parameters:<dd><p><dl compact>
+<p><dt>dbenv<dd>The handle returned from the <a href="../../api_c/env_create.html">db_env_create</a> call which identifies
+the environment in which recovery is running.
+<p><dt>rec<dd>The <b>rec</b> parameter is the record being recovered.
+<p><dt>lsn<dd>The log sequence number of the record being recovered.
+<p><dt>op<dd>A parameter of type db_recops which indicates what operation is being run
+(DB_TXN_OPENFILES, DB_TXN_ABORT, DB_TXN_BACKWARD_ROLL, DB_TXN_FORWARD_ROLL).
+<p><dt>info<dd>A structure passed by the dispatch function.  It is used to contain a list
+of committed transactions and information about files that may have been
+deleted.
+</dl>
+<p>The recovery function is called on each record read from the log during
+system recovery or transaction abort.
+<p>The recovery function is created in the file PREFIX_rtemp.c since it
+contains templates for recovery functions.  The actual recovery functions
+must be written manually, but the templates usually provide a good starting
+point.
+<p><dt>The print function:<dd>The print function takes the same parameters as the recover function so
+that it is simple to dispatch both to simple print functions as well as
+to the actual recovery functions.  This is useful for debugging purposes
+and is used by the <a href="../../utility/db_printlog.html">db_printlog</a> utility to produce a human-readable
+version of the log.  All parameters except the <b>rec</b> and
+<b>lsnp</b> parameters are ignored.  The <b>rec</b> parameter contains
+the record to be printed.
+</dl>
+One additional function, an initialization function,
+is created for each <b>.src</b> file.
+<p><dl compact>
+<p><dt>The initialization function has the following parameters:<dd><p><dl compact>
+<p><dt>dbenv<dd>The environment handle returned by <a href="../../api_c/env_create.html">db_env_create</a>.
+</dl>
+<p>The recovery initialization function registers each log record type
+declared with the recovery system, so that the appropriate function is
+called during recovery.
+</dl>
+<h3>Using Automatically Generated Routines</h3>
+<p>Applications use the automatically generated functions as follows:
+<p><ol>
+<p><li>When the application starts,
+call the <a href="../../api_c/env_set_rec_init.html">DBENV-&gt;set_recovery_init</a> with your recovery
+initialization function so that the initialization function is called
+at the appropriate time.
+<p><li>Issue a <a href="../../api_c/txn_begin.html">txn_begin</a> call before any operations you wish
+to be transaction protected.
+<p><li>Before accessing any data, issue the appropriate lock call to
+lock the data (either for reading or writing).
+<p><li>Before modifying any data that is transaction protected, issue
+a call to the appropriate log function.
+<p><li>Issue a <a href="../../api_c/txn_commit.html">txn_commit</a> to save all of the changes or a
+<a href="../../api_c/txn_abort.html">txn_abort</a> to cancel all of the modifications.
+</ol>
+<p>The recovery functions (described below) can be called in two cases:
+<p><ol>
+<p><li>From the recovery daemon upon system failure, with op set to
+DB_TXN_FORWARD_ROLL or DB_TXN_BACKWARD_ROLL.
+<p><li>From <a href="../../api_c/txn_abort.html">txn_abort</a>, if it is called to abort a transaction, with
+op set to DB_TXN_ABORT.
+</ol>
+<p>For each log record type you declare, you must write the appropriate
+function to undo and redo the modifications.  The shell of these functions
+will be generated for you automatically, but you must fill in the details.
+<p>Your code should be able to detect whether the described modifications
+have been applied to the data or not.  The function will be called with
+the "op" parameter set to DB_TXN_ABORT when a transaction that wrote the
+log record aborts and with DB_TXN_FORWARD_ROLL and DB_TXN_BACKWARD_ROLL
+during recovery.  The actions for DB_TXN_ABORT and DB_TXN_BACKWARD_ROLL
+should generally be the same.  For example, in the access methods, each
+page contains the log sequence number of the most recent log record that
+describes a modification to the page.  When the access method changes a
+page it writes a log record describing the change and including the the
+LSN that was on the page before the change.  This LSN is referred to as
+the previous LSN.  The recovery functions read the page described by a
+log record and compare the log sequence number (LSN) on the page to the
+LSN they were passed.  If the page LSN is less than the passed LSN and
+the operation is undo, no action is necessary (because the modifications
+have not been written to the page).  If the page LSN is the same as the
+previous LSN and the operation is redo, then the actions described are
+reapplied to the page.  If the page LSN is equal to the passed LSN and
+the operation is undo, the actions are removed from the page; if the page
+LSN is greater than the passed LSN and the operation is redo, no further
+action is necessary.  If the action is a redo and the LSN on the page is
+less than the previous LSN in the log record this is an error, since this
+could only happen if some previous log record was not processed.
+<p>Please refer to the internal recovery functions in the Berkeley DB library
+(found in files named XXX_rec.c) for examples of how recovery functions
+should work.
+<h3>Non-conformant Logging</h3>
+<p>If your application cannot conform to the default logging and recovery
+structure, then you will have to create your own logging and recovery
+functions explicitly.
+<p>First, you must decide how you will dispatch your records.  Encapsulate
+this algorithm in a dispatch function that is passed to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>.
+The arguments for the dispatch function are as follows:
+<p><dl compact>
+<p><dt>dbenv<dd>The environment handle returned by <a href="../../api_c/env_create.html">db_env_create</a>.
+<p><dt>rec<dd>The record being recovered.
+<p><dt>lsn<dd>The log sequence number of the record to be recovered.
+<p><dt>op<dd>Indicates what operation of recovery is needed (openfiles, abort, forward roll
+or backward roll).
+<p><dt>info<dd>An opaque value passed to your function during system recovery.
+</dl>
+<p>When you abort a transaction, <a href="../../api_c/txn_abort.html">txn_abort</a> will read the last log
+record written for the aborting transaction and will then call your
+dispatch function.  It will continue looping, calling the dispatch
+function on the record whose LSN appears in the lsn parameter of the
+dispatch call (until a NULL LSN is placed in that field).  The dispatch
+function will be called with the op set to DB_TXN_ABORT.
+<p>Your dispatch function can do any processing necessary.  See the code
+in db/db_dispatch.c for an example dispatch function (that is based on
+the assumption that the transaction ID, previous LSN, and record type
+appear in every log record written).
+<p>If you do not use the default recovery system, you will need to construct
+your own recovery process based on the recovery program provided in
+db_recover/db_recover.c.  Note that your recovery functions will need to
+correctly process the log records produced by calls to <a href="../../api_c/txn_begin.html">txn_begin</a>
+and <a href="../../api_c/txn_commit.html">txn_commit</a>.

+<p>
+<h1 align=center>Building multi-threaded applications</h1>
+<p>The Berkeley DB library is not itself multi-threaded.  The library was
+deliberately architected to not use threads internally because of the
+portability problems that using threads within the library would
+introduce.
+<p>Berkeley DB supports multi-threaded applications with the caveat that it loads
+and calls functions that are commonly available in C language environments.
+Other than this usage, Berkeley DB has no static data and maintains no local
+context between calls to Berkeley DB functions.
+<p>Environment and database object handles returned from Berkeley DB library
+functions are free-threaded.  No other object handles returned from
+the Berkeley DB library are free-threaded.
+<p>The following rules should be observed when using threads to
+access the Berkeley DB library:
+<p><ol>
+<p><li>The <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> flag must be specified to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a>
+and <a href="../../api_c/db_open.html">DB-&gt;open</a> functions if the Berkeley DB handles returned by those interfaces
+will be used in the context of more than one thread.  Setting the
+<a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> flag inconsistently may result in database corruption.
+<p>Threading is assumed in the Java API, so no special flags are required,
+and Berkeley DB functions will always behave as if the <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> flag
+was specified.
+<p>Only a single thread may call the <a href="../../api_c/env_close.html">DBENV-&gt;close</a> or <a href="../../api_c/db_close.html">DB-&gt;close</a> functions
+for a returned environment or database handle.
+<p>No other Berkeley DB handles are free-threaded, for example, cursors and
+transactions may not span threads as their returned handles are not
+free-threaded.
+<p><li>When using the non-cursor Berkeley DB calls to retrieve key/data items (e.g.,
+<a href="../../api_c/db_get.html">DB-&gt;get</a>), the memory referenced by the pointer stored into the
+Dbt is only valid until the next call to Berkeley DB using the DB handle
+returned by <a href="../../api_c/db_open.html">DB-&gt;open</a>.  This includes any use of the returned
+DB handle, including by another thread of control within the
+process.
+<p>For this reason, if the <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> handle was specified to the
+<a href="../../api_c/db_open.html">DB-&gt;open</a> function, either <a href="../../api_c/dbt.html#DB_DBT_MALLOC">DB_DBT_MALLOC</a>, <a href="../../api_c/dbt.html#DB_DBT_REALLOC">DB_DBT_REALLOC</a>
+or <a href="../../api_c/dbt.html#DB_DBT_USERMEM">DB_DBT_USERMEM</a> must be specified in the <a href="../../api_c/dbt.html">DBT</a> when
+performing any non-cursor key or data retrieval.
+<p><li>The <a href="../../api_c/dbc_get.html#DB_CURRENT">DB_CURRENT</a>, <a href="../../api_c/dbc_get.html#DB_NEXT">DB_NEXT</a> and <a href="../../api_c/dbc_get.html#DB_PREV">DB_PREV</a> flags to the
+<a href="../../api_c/log_get.html">log_get</a> function may not be used by a free-threaded handle.  If
+such calls are necessary, a thread should explicitly create a unique
+environment handle by separately calling <a href="../../api_c/env_open.html">DBENV-&gt;open</a> without
+specifying <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a>.
+<p><li>Each database operation (i.e., any call to a function underlying the
+handles returned by <a href="../../api_c/db_open.html">DB-&gt;open</a> and <a href="../../api_c/db_cursor.html">DB-&gt;cursor</a>) is normally
+performed on behalf of a unique locker.  If, within a single thread of
+control, multiple calls on behalf of the same locker are desired, then
+transactions must be used.  For example, consider the case where a
+cursor scan locates a record, and then based on that record, accesses
+some other item in the database.  If these operations are done using
+the default lockers for the handle, they may conflict.  If the
+application wishes to guarantee that the operations do not conflict,
+locks must be obtained on behalf of a transaction, instead of the
+default locker ID, and a transaction must be specified to subsequent
+<a href="../../api_c/db_cursor.html">DB-&gt;cursor</a> and other Berkeley DB calls.
+<p><li>Transactions may not span threads.  Each transaction must begin and end
+in the same thread, and each transaction may only be used by a single
+thread.
+<p>Cursors may not span transactions or threads.  Each cursor must be
+allocated and de-allocated within the same transaction and within
+the same thread.
+<p><li>User-level synchronization mutexes must have been implemented for the
+compiler/architecture combination.  Attempting to specify the DB_THREAD
+flag will fail if fast mutexes are not available.
+<p>If blocking mutexes are available, for example POSIX pthreads, they will
+be used.  Otherwise, the Berkeley DB library will make a system call to pause
+for some amount of time when it is necessary to wait on a lock.  This may
+not be optimal, especially in a thread-only environment where it will be
+more efficient to explicitly yield the processor to another thread.
+<p>It is possible to specify a yield function on an per-application basis.
+See <a href="../../api_c/set_func_yield.html">db_env_set_func_yield</a> for more information.
+<p>It is possible to specify the number of attempts that will be made to
+acquire the mutex before waiting.  Se <a href="../../api_c/env_set_tas_spins.html">db_env_set_tas_spins</a> for
+more information.

+<h1 align=center>Name spaces</h1>
+<p>The Berkeley DB library is careful to avoid C language programmer name spaces,
+but there are a few potential areas for concern, mostly in the Berkeley DB
+include file db.h.  The db.h include file defines a number of types and
+strings.  Where possible, all of these types and strings are prefixed with
+"DB_" or "db_".  There are a few notable exceptions.
+<p>The Berkeley DB library uses a macro named "__P" to configure for systems that
+do not provide ANSI C function prototypes.  This could potentially collide
+with other systems using a "__P" macro for similar or different purposes.
+<p>The Berkeley DB library needs information about specifically sized types for
+each architecture.  If they are not provided by the system, they are
+typedef'd in the db.h include file.  The types which may be typedef'd
+by db.h include the following: u_int8_t, int16_t, u_int16_t, int32_t,
+u_int32_t, u_char, u_short, u_int and u_long.
+<p>The Berkeley DB library declares a number of external routines.  All of these
+routines are prefixed with the strings "db_", "lock_", "log_", "memp_"
+or "txn_".  All internal routines are prefixed with the strings "__db_",
+"__lock_," "__log_", "__memp_" or "__txn_".
+<p>Berkeley DB environments create or use some number of files in environment home
+directories.  These files are named <a href="../../ref/env/naming.html#DB_CONFIG">DB_CONFIG</a>, "log.NNNNNNNNNN"
+(e.g., log.0000000003), or with the string prefix "__db" (e.g., __db.001).
+Database files that match these names should not be created in the
+environment directory.

+<h1 align=center>Recovery implementation</h1>
+<p>The physical recovery process works as follows:
+<p>First, find the last checkpoint that completed.  Since the system may
+have crashed while writing a checkpoint, this implies finding the
+second-to-last checkpoint in the log files.  Read forward from this
+checkpoint, opening any database files for which modifications are found
+in the log.
+<p>Then, read backward from the end of the log.  For each commit record
+encountered, record its transaction ID.  For every other data update
+record, find the transaction ID of the record.  If that transaction ID
+appears in the list of committed transactions, do nothing; if it does not
+appear in the committed list, then call the appropriate recovery routine
+to undo the operation.
+<p>In the case of catastrophic recovery, this roll-backward pass continues
+through all the present log files.  In the case of normal recovery, this
+pass continues until we find a checkpoint written before the second-to-last
+checkpoint described above.
+<p>When the roll-backward pass is complete, the roll-forward pass begins at
+the point where the roll-backward pass ended.  Each record is read and if
+its transaction id is in the committed list, then the appropriate recovery
+routine is called to redo the operation if necessary.
+<p>In a distributed transaction environment, there may be transactions that
+are prepared, but not yet committed.  If these transactions are XA
+transactions, then they are rolled forward to their current state, and an
+active transaction corresponding to it is entered in the transaction table
+so that the XA transaction manager may call either transaction abort or
+commit, depending on the outcome of the overall transaction.  If the
+transaction is not an XA transaction, then it is aborted like any other
+transactions would be.

+large file functionality in Solaris 2.6 but which still runs on Solaris
+2.5.  <a href="solaris.txt">Example code</a> that supports this is

+<p>The Berkeley DB library has a number of object handles.  The following table
+lists those handles, their scope, and if they are free-threaded, that
+is, if multiple threads within a process can share them.
+<p><dl compact>
+<p><dt>DB_ENV<dd>The DB_ENV handle is created by the <a href="../../api_c/env_create.html">db_env_create</a> function and
+references a Berkeley DB database environment, a collection of
+databases and Berkeley DB subsystems.  DB_ENV handles are free-threaded
+if the <a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> flag is specified to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function
+when the environment is opened.  The handle should not be closed while
+any other handle remains open that is using it as a reference
+(e.g., DB or DB_TXN).  Once either the <a href="../../api_c/env_close.html">DBENV-&gt;close</a> or
+<a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> functions are called, the handle may not be accessed again,
+regardless of the function's return.
+<p><dt>DB_TXN<dd>The DB_TXN handle is created by the <a href="../../api_c/txn_begin.html">txn_begin</a> function and
+references a single transaction.  The handle is not free-threaded, and
+transactions may not span threads nor may transactions be used by more
+than a single thread.
+Once the
+<a href="../../api_c/txn_abort.html">txn_abort</a> or <a href="../../api_c/txn_commit.html">txn_commit</a> functions are called, the handle may
+not be accessed again, regardless of the function's return.
+In addition, parent transactions may not issue
+any Berkeley DB operations, except for <a href="../../api_c/txn_begin.html">txn_begin</a>, <a href="../../api_c/txn_abort.html">txn_abort</a>
+and <a href="../../api_c/txn_commit.html">txn_commit</a>, while it has active child transactions (child
+transactions that have not yet been committed or aborted).
+<p><dt>DB_MPOOLFILE<dd>The DB_MPOOLFILE handle references an open file in the shared
+memory buffer pool of the database environment.  The handle is not
+free-threaded.  Once the <a href="../../api_c/memp_fclose.html">memp_fclose</a> function is called, the handle may
+not be accessed again, regardless of the function's return.
+<p><dt>DB<dd>The DB handle is created by the <a href="../../api_c/db_create.html">db_create</a> function and
+references a single Berkeley DB database, which may or may not be part of a
+database environment.  DB handles are free-threaded if the
+<a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> flag is specified to the <a href="../../api_c/db_open.html">DB-&gt;open</a> function when the
+database is opened, or if the database environment in which the database
+is opened is free-threaded.  The handle should not be closed while any
+other handle that references the database is in use, e.g., database
+handles must not be closed while cursor handles into the database remain
+open, or transactions which include operations on the database have not
+yet been committed or aborted.  Once the <a href="../../api_c/db_close.html">DB-&gt;close</a>,
+<a href="../../api_c/db_remove.html">DB-&gt;remove</a> or <a href="../../api_c/db_rename.html">DB-&gt;rename</a> functions are called, the handle may
+not be accessed again, regardless of the function's return.
+<p><dt>DBC<dd>The DBC handle references a cursor into a Berkeley DB database.  The
+handle is not free-threaded and cursors may not span threads nor may
+cursors be used by more than a single thread.  If the cursor is to be
+used to perform operations on behalf of a transaction, the cursor must
+be opened and closed within the context of that single transaction.
+Once <a href="../../api_c/dbc_close.html">DBcursor-&gt;c_close</a> has been called, the handle may not be accessed
+again, regardless of the function's return.

+<h1>
+Introduction
+</h1>
+<p>
+The Berkeley Database (Berkeley DB) is an embedded database system
+that can be used in applications requiring high-performance
+concurrent storage and retrieval of key/value pairs.  The software
+is distributed as a library that can be linked directly into an
+application.
+It provides a variety of programmatic interfaces,
+including callable APIs for C, C++, Perl, Tcl and Java.
+Users may download Berkeley DB from Sleepycat Software's Web site,
+at
+<a href="http://www.sleepycat.com">www.sleepycat.com</a>.
+<p>
+Sleepycat distributes Berkeley DB as an Open Source product.  The company
+collects license fees for certain uses of the software and sells support
+and services.
+<h2>
+History
+</h2>
+<p>
+Berkeley DB began as a new implementation of a hash access method
+to replace both
+<tt>hsearch</tt>
+and the various
+<tt>dbm</tt>
+implementations
+(<tt>dbm</tt> from AT&T,
+<tt>ndbm</tt>
+from Berkeley, and
+<tt>gdbm</tt>
+from the GNU project).
+In 1990 Seltzer and Yigit produced a package called Hash to do this
+<a href="#Selt91">[Selt91]</a>.
+<p>
+The first general release of Berkeley DB, in 1991,
+included some interface changes and a new B+tree access method.
+At roughly the same time, Seltzer and Olson
+developed a prototype transaction
+system based on Berkeley DB, called LIBTP <a href="#Selt92">[Selt92]</a>,
+but never released the code.
+<p>
+The 4.4BSD UNIX release included Berkeley DB 1.85 in 1992.
+Seltzer and Bostic maintained the code in the early 1990s
+in Berkeley and in Massachusetts.
+Many users adopted the code during this period.
+<p>
+By mid-1996,
+users wanted commercial support for the software.
+In response, Bostic and Seltzer formed Sleepycat Software.
+The company  enhances, distributes, and
+supports Berkeley DB and supporting software and documentation.
+Sleepycat released version 2.1 of Berkeley DB in mid-1997
+with important new features, including
+support for concurrent access to databases.
+The company makes about three commercial releases a year,
+and most recently shipped version 2.8.
+<h2>
+Overview of Berkeley DB
+</h2>
+<p>
+The C interfaces in Berkeley DB permit
+<tt>dbm</tt>-style
+record management
+for databases,
+with significant extensions to handle duplicate data items elegantly,
+to deal with concurrent access, and to provide transactional
+support so that multiple changes can be simultaneously committed
+(so that they are made permanent) or rolled back (so that the
+database is restored to its state at the beginning of the transaction).
+<p>
+C++ and Java interfaces provide a small set of classes for
+operating on a database.  The main class in both cases is called
+<tt>Db</tt>,
+and provides methods that encapsulate the
+<tt>dbm</tt>-style
+interfaces that the C interfaces provide.
+<p>
+Tcl and Perl interfaces allow developers working in those languages
+to use Berkeley DB in their applications.
+Bindings for both languages are included in the distribution.
+<p>
+Developers may compile their applications and link in Berkeley DB
+statically or dynamically.
+<h2>
+How Berkeley DB is used
+</h2>
+<p>
+The Berkeley DB library supports concurrent access to databases.
+It can be linked
+into standalone applications, into a collection of cooperating applications,
+or into servers that handle requests and do database operations on
+behalf of clients.
+<p>
+Compared to using a standalone database management system, Berkeley
+DB is easy to understand and simple to use.  The
+software stores and retrieves records, which consist of key/value pairs.
+Keys are used to locate items and can be any data type or structure
+supported by the programming language.
+<p>
+The programmer can provide the functions that Berkeley DB uses to
+operate on keys.
+For example,
+B+trees can use a custom comparison function,
+and the Hash access method can use a custom hash function.
+Berkeley DB uses default functions if none are supplied.
+Otherwise, Berkeley DB does not examine or interpret either keys
+or values in any way.
+Values may be arbitrarily long.
+<p>
+It is also important to understand what Berkeley DB is not.
+It is not a database server that handles network requests.  It is not an
+SQL engine that executes queries.  It is not a relational or object-oriented
+database management system.
+<p>
+It is possible to build any of those on top of Berkeley DB,
+but the package, as distributed,
+is an embedded database engine.  It has been designed
+to be portable, small, fast, and reliable.
+<h2>
+Applications that use Berkeley DB
+</h2>
+<p>
+Berkeley DB is embedded in a variety of proprietary and Open Source
+software packages.
+This section highlights a few of the products that use it.
+<p>
+Directory servers, which do data storage and retrieval using the
+Local Directory Access Protocol (LDAP), provide naming and directory
+lookup service on local-area networks.
+This service is,
+essentially,
+database query and update,
+but uses a simple protocol rather than SQL or ODBC.
+Berkeley DB is the embedded data manager in the majority of deployed
+directory servers today,
+including LDAP servers from Netscape,
+MessageDirect (formerly Isode),
+and others.
+<p>
+Berkeley DB is also embedded in a large number of mail servers.
+Intermail,
+from Software.com,
+uses Berkeley DB as a message store
+and as the backing store for its directory server.
+The sendmail server
+(including both the commercial Sendmail Pro offering from Sendmail,
+Inc. and the version distributed by sendmail.org)
+uses Berkeley DB to store aliases and other information.
+Similarly,
+Postfix (formerly VMailer) uses Berkeley DB
+to store administrative information.
+<p>
+In addition,
+Berkeley DB is embedded in a wide variety of other software products.
+Example applications include managing access control lists,
+storing user keys in a public-key infrastructure,
+recording machine-to-network-address mappings in address servers,
+and storing configuration and device information in video
+post-production software.
+<p>
+Finally,
+Berkeley DB is a part of many other Open Source software packages
+available on the Internet.
+For example,
+the software is embedded in the Apache Web server and the Gnome desktop.
+<h1>
+Access Methods
+</h1>
+<p>
+In database terminology, an access method is the disk-based structure
+used to store data and the operations available on that structure.
+For example, many database systems support a B+tree access method.
+B+trees allow equality-based lookups (find keys equal to some constant),
+range-based lookups (find keys between two constants) and record
+insertion and deletion.
+<p>
+Berkeley DB supports three access methods: B+tree,
+Extended Linear Hashing (Hash),
+and Fixed- or Variable-length Records (Recno).
+All three operate on records composed of a key and a data value.
+In the B+tree and Hash access methods, keys can have arbitrary structure.
+In the Recno access method, each record is assigned a record number, which
+serves as the key.
+In all the access methods, the
+value can have arbitrary structure.
+The programmer can supply comparison or hashing functions for keys,
+and Berkeley DB stores and retrieves values without
+interpreting them.
+<p>
+All of the access methods use the host filesystem as a backing store.
+<h2>
+Hash
+</h2>
+<p>
+Berkeley DB includes a Hash access method that implements extended
+linear hashing <a href="#Litw80">[Litw80]</a>.
+Extended linear hashing adjusts the hash function as the hash
+table grows, attempting to keep all buckets underfull in the steady
+state.
+<p>
+The Hash access method supports insertion and deletion of records and
+lookup by exact match only.  Applications may iterate over all records
+stored in a table, but the order in which they are returned is undefined.
+<h2>
+B+tree
+</h2>
+<p>
+Berkeley DB includes a B+tree <a href="#Come79">[Come79]</a> access method.
+B+trees store records of key/value pairs in leaf pages,
+and pairs of (key, child page address) at internal nodes.
+Keys in the tree are stored in sorted order,
+where the order is determined by the comparison function supplied when the
+database was created.
+Pages at the leaf level of the tree include pointers
+to their neighbors to simplify traversal.  B+trees support lookup by
+exact match (equality) or range (greater than or equal to a key).
+Like Hash tables, B+trees support record insertion,
+deletion, and iteration over all records in the tree.
+<p>
+As records are inserted and pages in the B+tree fill up, they are split,
+with about half the keys going into a new peer page at the same level in
+the tree.
+Most B+tree implementations leave both nodes half-full after a split.
+This leads to poor performance in a common case, where the caller inserts
+keys in order.
+To handle this case, Berkeley DB keeps track of the insertion order,
+and splits pages unevenly to keep pages fuller.
+This reduces tree size, yielding better search performance and smaller
+databases.
+<p>
+On deletion, empty pages are coalesced by reverse splits
+into single pages.
+The access method does no other page balancing on insertion
+or deletion.
+Keys are not moved among pages at every update
+to keep the tree well-balanced.  While this could improve search times
+in some cases, the additional code complexity leads to slower updates and
+is prone to deadlocks.
+<p>
+For simplicity, Berkeley DB B+trees do no prefix compression of keys
+at internal or leaf nodes.
+<h2>
+Recno
+</h2>
+<p>
+Berkeley DB includes a fixed- or variable-length record access method,
+called
+<i>Recno</i>.
+The Recno access method assigns logical record numbers to each
+record,
+and can search for and update records by record number.
+Recno is able,
+for example,
+to load a text file into a database,
+treating each line as a record.
+This permits fast searches by line number for applications like
+text editors <a href="#Ston82">[Ston82]</a>.
+<p>
+Recno is actually built
+on top of the B+tree access method and provides a simple interface
+for storing sequentially-ordered data values.
+The Recno access method generates keys internally.
+The programmer's view of the values is that
+they are numbered sequentially from one.
+Developers can choose to have records automatically renumbered
+when lower-numbered records are added or deleted.
+In this case, new keys can be inserted between existing keys.
+<h1>
+Features
+</h1>
+<p>
+This section describes important features of Berkeley DB.
+In general,
+developers can choose which features are useful to them,
+and use only those that are required by their application.
+<p>
+For example,
+when an application opens a database, it can declare the degree of
+concurrency and recovery that it requires.  Simple stand-alone applications,
+and in particular ports of applications that used
+<tt>dbm</tt>
+or one of its
+variants, generally do not require concurrent access or crash recovery.
+Other applications, such as enterprise-class database management systems
+that store sales transactions or other critical data, need full
+transactional service.  Single-user operation is faster than multi-user
+operation, since no overhead is incurred by locking.  Running with
+the recovery system disabled is faster than running with it enabled,
+since log records need not be written when changes are made to the
+database.
+<p>
+In addition, some core subsystems, including the locking system and
+the logging facility,
+can be used outside the context of the access methods as well.
+Although few users have chosen to do so, it is possible to
+use only the lock manager in Berkeley DB to control concurrency
+in an application, without using any of the standard database services.
+Alternatively, the caller can integrate locking of non-database resources
+with Berkeley DB's transactional two-phase locking system, to impose
+transaction semantics on objects outside the database.
+<h2>
+Programmatic interfaces
+</h2>
+<p>
+Berkeley DB defines a simple API for database management.
+The package does not include industry-standard
+programmatic interfaces such as Open Database Connectivity (ODBC),
+Object Linking and Embedding for Databases (OleDB), or Structured
+Query Language (SQL).  These interfaces, while useful, were
+designed to promote interoperability of database systems, and not
+simplicity or performance.
+<p>
+In response to customer demand,
+Berkeley DB 2.5 introduced support for the XA standard <a href="#Open94">[Open94]</a>.
+XA permits Berkeley DB to participate in distributed transactions
+under a transaction processing monitor like Tuxedo from BEA Systems.
+Like XA, other standard interfaces can be built on top of the
+core system.
+The standards do not belong inside Berkeley DB,
+since not all applications need them.
+<h2>
+Working with records
+</h2>
+<p>
+A database user may need to search for particular keys in a database,
+or may simply want to browse available records.
+Berkeley DB supports both keyed access,
+to find one or more records with a given key,
+or sequential access,
+to retrieve all the records in the database one at a time.
+The order of the records returned during sequential scans
+depends on the access method.
+B+tree and Recno databases return records in sort order,
+and Hash databases return them in apparently random order.
+<p>
+Similarly,
+Berkeley DB defines simple interfaces for inserting,
+updating,
+and deleting records in a database.
+<h2>
+Long keys and values
+</h2>
+<p>
+Berkeley DB manages keys and values as large as
+2<sup>32</sup> bytes.
+Since the time required to copy a record is proportional to its size,
+Berkeley DB includes interfaces that operate on partial records.
+If an application requires only part of a large record,
+it requests partial record retrieval,
+and receives just the bytes that it needs.
+The smaller copy saves both time and memory.
+<p>
+Berkeley DB allows the programmer to define the data types of
+keys and values.
+Developers use any type expressible in the programming language.
+<h2>
+Large databases
+</h2>
+<p>
+A single database managed by Berkeley DB can be up to 2<sup>48</sup>
+bytes,
+or 256 petabytes,
+in size.
+Berkeley DB uses the host filesystem as the backing store
+for the database,
+so large databases require big file support from the operating system.
+Sleepycat Software has customers using Berkeley DB
+to manage single databases in excess of 100 gigabytes.
+<h2>
+Main memory databases
+</h2>
+<p>
+Applications that do not require persistent storage can create
+databases that exist only in main memory.
+These databases bypass the overhead imposed by the I/O system
+altogether.
+<p>
+Some applications do need to use disk as a backing store,
+but run on machines with very large memory.
+Berkeley DB is able to manage very large shared memory regions
+for cached data pages,
+log records,
+and lock management.
+For example,
+the cache region used for data pages may be gigabytes in size,
+reducing the likelihood that any read operation will need to
+visit the disk in the steady state.
+The programmer declares the size of the cache region at
+startup.
+<p>
+Finally, many operating systems provide memory-mapped file services
+that are much faster than their general-purpose file system
+interfaces.
+Berkeley DB can memory-map its database files for read-only database use.
+The application operates on records stored directly on the pages,
+with no cache management overhead.
+Because the application gets pointers directly into the
+Berkeley DB pages,
+writes cannot be permitted.
+Otherwise,
+changes could bypass the locking and logging systems,
+and software errors could corrupt the database.
+Read-only applications can use Berkeley DB's memory-mapped
+file service to improve performance on most architectures.
+<h2>
+Configurable page size
+</h2>
+<p>
+Programmers declare the size of the pages used by their access
+methods when they create a database.
+Although Berkeley DB provides reasonable defaults,
+developers may override them to control system performance.
+Small pages reduce the number of records that fit on a single page.
+Fewer records on a page means that fewer records are locked when
+the page is locked,
+improving concurrency.
+The per-page overhead is proportionally higher with smaller pages,
+of course,
+but developers can trade off space for time as an application requires.
+<h2>
+Small footprint
+</h2>
+<p>
+Berkeley DB is a compact system.
+The full package, including all access methods, recoverability,
+and transaction support
+is roughly 175K of text space on common architectures. 
+<h2>
+Cursors
+</h2>
+<p>
+In database terminology, a cursor is a pointer into an access method
+that can be called iteratively to return records in sequence.  Berkeley
+DB includes cursor interfaces for all access methods.  This permits,
+for example, users to traverse a B+tree and view records in order.
+Pointers to records in cursors are persistent, so that once fetched,
+a record may be updated in place.  Finally, cursors support access to
+chains of duplicate data items in the various access methods.
+<h2>
+Joins
+</h2>
+<p>
+In database terminology,
+a join is an operation that spans multiple separate
+tables (or in the case of Berkeley DB, multiple separate DB files).
+For example, a company may store information about its customers
+in one table and information about sales in another.  An application
+will likely want to look up sales information by customer name; this
+requires matching records in the two tables that share a common
+customer ID field.
+This combining of records from multiple tables is called a join.
+<p>
+Berkeley DB includes interfaces for joining two or more tables.
+<h2>
+Transactions
+</h2>
+<p>
+Transactions have four properties <a href="#Gray93">[Gray93]</a>:
+<ul>
+<li>
+They are atomic.  That is, all of the changes made in a single
+transaction must be applied at the same instant or not at all.
+This permits, for example, the transfer of money between two
+accounts to be accomplished, by making the reduction of the
+balance in one account and the increase in the other into a
+single, atomic action.
+</li>
+<li>
+They must be consistent.  That is, changes to the database
+by any transaction cannot leave the database in an illegal
+or corrupt state.
+</li>
+<li>
+They must be isolatable.  Regardless of the number of users
+working in the database at the same time, every user must have
+the illusion that no other activity is going on.
+</li>
+<li>
+They must be durable.  Even if the disk that stores the database
+is lost, it must be possible to recover the database to its last
+transaction-consistent state.
+</li>
+</ul>
+<p>
+This combination of properties -- atomicity, consistency, isolation, and
+durability -- is referred to as ACIDity in the literature.  Berkeley DB,
+like most database systems, provides ACIDity using a collection of core
+services.
+<p>
+Programmers can choose to use Berkeley DB's transaction services
+for applications that need them.
+<h3>
+Write-ahead logging
+</h3>
+<p>
+Programmers can enable the logging system when they start up Berkeley DB.
+During a transaction,
+the application makes a series of changes to the database.
+Each change is captured in a log entry,
+which holds the state of the database record
+both before and after the change.
+The log record is guaranteed
+to be flushed to stable storage before any of the changed data pages
+are written.
+This behavior -- writing the log before the data pages -- is called
+<i>write-ahead logging</i>.
+<p>
+At any time during the transaction,
+the application can
+<i>commit</i>,
+making the changes permanent,
+or
+<i>roll back</i>,
+cancelling all changes and restoring the database to its
+pre-transaction state.
+If the application
+rolls back the transaction, then the log holds the state of all
+changed pages prior to the transaction, and Berkeley DB simply
+restores that state.
+If the application commits the transaction,
+Berkeley DB writes the log records to disk.
+In-memory copies of the data pages already reflect the changes,
+and will be flushed as necessary during normal processing.
+Since log writes are sequential, but data page
+writes are random, this improves performance.
+<h3>
+Crashes and recovery
+</h3>
+<p>
+Berkeley DB's write-ahead log is used by the transaction
+system to commit or roll back transactions.
+It also gives the recovery system the information that
+it needs to protect against data loss or corruption
+from crashes.
+Berkeley DB is able to survive application crashes,
+system crashes,
+and even catastrophic failures like the loss of a hard
+disk,
+without losing any data.
+<p>
+Surviving crashes requires data stored in several different places.
+During normal processing,
+Berkeley DB has copies of active log records and recently-used
+data pages in memory.
+Log records are flushed to the log disk when transactions commit.
+Data pages trickle out to the data disk as pages move through
+the buffer cache.
+Periodically,
+the system administrator backs up the data disk,
+creating a safe copy of the database at a particular instant.
+When the database is backed up,
+the log can be truncated.
+For maximum robustness,
+the log disk and data disk should be separate devices.
+<p>
+Different system failures can destroy memory,
+the log disk,
+or the data disk.
+Berkeley DB is able to survive the loss of any one
+of these repositories
+without losing any committed transactions.
+<p>
+If the computer's memory is lost,
+through an application or operating system crash,
+then the log holds all committed transactions.
+On restart,
+the recovery system rolls the log forward against
+the database,
+reapplying any changes to on-disk pages that were in memory at the
+time of the crash.
+Since the log contains pre- and post-change state for
+transactions,
+the recovery system also uses the log to restore any pages to
+their original state if they were modified by transactions
+that never committed.
+<p>
+If the data disk is lost,
+the system administrator can restore the most recent copy from backup.
+The recovery system will roll the entire log forward against
+the original database,
+reapplying all committed changes.
+When it finishes,
+the database will contain every change made by every
+transaction that ever committed.
+<p>
+If the log disk is lost,
+then the recovery system can use the in-memory copies of
+log entries to roll back any uncommitted transactions,
+flush all in-memory database pages to the data disk,
+and shut down gracefully.
+At that point,
+the system administrator can back up the database disk,
+install a new log disk,
+and restart the system.
+<h3>
+Checkpoints
+</h3>
+<p>
+Berkeley DB includes a checkpointing service that interacts
+with the recovery system.
+During normal processing,
+both the log and the database are changing continually.
+At any given instant,
+the on-disk versions of the two are not guaranteed to be consistent.
+The log probably contains changes that are not yet in the database.
+<p>
+When an application makes a
+<i>checkpoint</i>,
+all committed changes in the log up to that point
+are guaranteed to be present on the data disk,
+too.
+Checkpointing is moderately expensive during normal processing,
+but limits the time spent recovering from crashes.
+<p>
+After an application or operating system crash,
+the recovery system only needs to go back two checkpoints
+to start rolling the log forward.
+(One checkpoint is not far enough.
+The recovery system cannot be sure that the most recent
+checkpoint completed --
+it may have been interrupted by the crash that forced the
+recovery system to run in the first place.)
+Without checkpoints,
+there is no way to be sure how long restarting after a crash will take.
+With checkpoints,
+the restart interval can be fixed by the programmer.
+Recovery processing can be guaranteed to complete in a second or two.
+<p>
+Software crashes are much more common than disk failures.
+Many developers want to guarantee that software bugs do not destroy data,
+but are willing to restore from tape,
+and to tolerate a day or two of lost work,
+in the unlikley event of a disk crash.
+With Berkeley DB,
+programmers may truncate the log at checkpoints.
+As long as the two most recent checkpoints are present,
+the recovery system can guarantee that no committed transactions
+are lost after a software crash.
+In this case,
+the recovery system does not require that the log and the
+data be on separate devices,
+although separating them can still improve performance
+by spreading out writes.
+<h3>
+Two-phase locking
+</h3>
+<p>
+Berkeley DB provides a service known as two-phase locking.
+In order to reduce the likelihood of deadlocks and to guarantee ACID
+properties, database systems manage locks in two phases.  First, during
+the operation of a transaction, they acquire locks, but never release
+them.  Second, at the end of the transaction, they release locks, but
+never acquire them.  In practice, most database systems, including Berkeley
+DB, acquire locks on demand over the course of the transaction, then
+flush the log, then release all locks.
+<p>
+Berkeley DB can lock entire database files, which correspond to tables,
+or individual pages in them.
+It does no record-level locking.
+By shrinking the page size,
+however,
+developers can guarantee that every page holds only a small
+number of records.
+This reduces contention. 
+<p>
+If locking is enabled,
+then read and write operations on a database acquire two-phase locks,
+which are held until the transaction completes.
+Which objects are locked and the order of lock acquisition
+depend on the workload for each transaction.
+It is possible for two or more transactions to deadlock,
+so that each is waiting for a lock that is held by another.  
+<p>
+Berkeley DB detects deadlocks and automatically rolls back
+one of the transactions.
+This releases the locks that it held  
+and allows the other transactions to continue.
+The caller is notified that its transaction did not complete,
+and may restart it.
+Developers can specify the deadlock detection interval
+and the policy to use in choosing a transaction to roll back.
+<p>
+The two-phase locking interfaces are separately callable by applications
+that link Berkeley DB, though few users have needed to use that facility
+directly.
+Using these interfaces,
+Berkeley DB provides a fast,
+platform-portable locking system for general-purpose use.
+It also lets users include non-database objects in a database transaction,
+by controlling access to them exactly as if they were inside the database.
+<p>
+The Berkeley DB two-phase locking facility is built on the fastest correct
+locking primitives that are supported by the underlying architecture.
+In the current implementation, this means that the locking system is
+different on the various UNIX platforms, and is still more different
+on Windows NT.  In our experience, the most difficult aspect of performance
+tuning is finding the fastest locking primitives that work correctly
+on a particular architecture and then integrating the new
+interface with the several that we already support.
+<p>
+The world would be a better place if the operating systems community
+would uniformly implement POSIX locking primitives and would guarantee
+that acquiring an uncontested lock was a fast operation.
+Locks must work both among threads in a single process
+and among processes.
+<h2>
+Concurrency
+</h2>
+<p>
+Good performance under concurrent operation is a critical design point
+for Berkeley DB.  Although Berkeley DB is itself not multi-threaded,
+it is thread-safe, and runs well in threaded applications.
+Philosophically,
+we view the use of threads and the choice of a threads package
+as a policy decision,
+and prefer to offer mechanism (the ability to run threaded or not),
+allowing applications to choose their own policies.
+<p>
+The locking, logging, and buffer pool subsystems all use shared memory
+or other OS-specific sharing facilities to communicate.  Locks, buffer
+pool fetches, and log writes behave in the same way across threads in
+a single process as they do across different processes on a single
+machine.
+<p>
+As a result, concurrent database applications may start up a new process
+for every single user, may create a single server which spawns a new
+thread for every client request, or may choose any policy in between.
+<p>
+Berkeley DB has been carefully designed to minimize contention
+and maximize concurrency.
+The cache manager allows all threads or processes to benefit from
+I/O done by one.
+Shared resources must sometimes be locked for exclusive access
+by one thread of control.
+We have kept critical sections small,
+and are careful not to hold critical resource locks across
+system calls that could deschedule the locking thread or process.
+Sleepycat Software has customers with hundreds of concurrent
+users working on a single database in production.
+<h1>
+Engineering Philosophy
+</h1>
+<p>
+Fundamentally, Berkeley DB is a collection of access methods with
+important facilities, like logging, locking, and transactional access
+underlying them.  In both the research and the commercial world,
+the techniques for building systems like Berkeley DB have been well-known
+for a long time.
+<p>
+The key advantage of Berkeley DB is the careful attention that has been
+paid to engineering details throughout its life.  We have carefully
+designed the system so that the core facilities, like locking and I/O,
+surface the right interfaces and are otherwise opaque to the caller.
+As programmers, we understand the value of simplicity and have worked
+hard to simplify the interfaces we surface to users of the
+database system.
+<p>
+Berkeley DB avoids limits in the code.  It places no practical limit
+on the size of keys, values, or databases; they may grow to occupy
+the available storage space.
+<p>
+The locking and logging subsystems have been carefully crafted to
+reduce contention and improve throughput by shrinking or eliminating
+critical sections, and reducing the sizes of locked regions and log
+entries.
+<p>
+There is nothing in the design or implementation of Berkeley DB that
+pushes the state of the art in database systems.  Rather, we have been
+very careful to get the engineering right.  The result is a system that
+is superior, as an embedded database system, to any other solution
+available.
+<p>
+Most database systems trade off simplicity for correctness.  Either the
+system is easy to use, or it supports concurrent use and survives system
+failures.  Berkeley DB, because of its careful design and implementation,
+offers both simplicity and correctness.
+<p>
+The system has a small footprint,
+makes simple operations simple to carry out (inserting a new record takes
+just a few lines of code), and behaves correctly in the face of heavy
+concurrent use, system crashes, and even catastrophic failures like loss
+of a hard disk.
+<h1>
+The Berkeley DB 2.x Distribution
+</h1>
+<p>
+Berkeley DB is distributed in source code form from
+<a href="http://www.sleepycat.com">www.sleepycat.com</a>.
+Users are free to download and build the software, and to use it in
+their applications.
+<h2>
+What is in the distribution
+</h2>
+<p>
+The distribution is a compressed archive file.
+It includes the source code for the Berkeley DB library,
+as well as documentation, test suites, and supporting utilities.
+<p>
+The source code includes build support for all supported platforms.
+On UNIX systems Berkeley DB uses the GNU autoconfiguration tool,
+<tt>autoconf</tt>,
+to identify the system and to build the library
+and supporting utilities.
+Berkeley DB includes specific build environments for other platforms,
+such as VMS and Windows.
+<h3>
+Documentation
+</h3>
+<p>
+The distributed system includes documentation in HTML format.
+The documentation is in two parts:
+a UNIX-style reference manual for use by programmers,
+and a reference guide which is tutorial in nature.
+<h3>
+Test suite
+</h3>
+<p>
+The software also includes a complete test suite, written in Tcl.
+We believe that the test suite is a key advantage of Berkeley DB
+over comparable systems.
+<p>
+First, the test suite allows users who download and build the software
+to be sure that it is operating correctly.
+<p>
+Second, the test suite allows us, like other commercial developers
+of database software, to exercise the system thoroughly at every
+release.  When we learn of new bugs, we add them to the test suite.
+We run the test suite continually during development cycles, and
+always prior to release.  The result is a much more reliable system
+by the time it reaches beta release.
+<h2>
+Binary distribution
+</h2>
+<p>
+Sleepycat makes compiled libraries and general binary distributions available
+to customers for a fee.
+<h2>
+Supported platforms
+</h2>
+<p>
+Berkeley DB runs on any operating system with a
+POSIX 1003.1 interface <a href="#IEEE96">[IEEE96]</a>,
+which includes virtually every UNIX system.
+In addition,
+the software runs on VMS,
+Windows/95,
+Windows/98,
+and Windows/NT.
+Sleepycat Software no longer supports deployment on sixteen-bit
+Windows systems.
+<h1>
+Berkeley DB 2.x Licensing
+</h1>
+<p>
+Berkeley DB 2.x is distributed as an Open Source product.  The software
+is freely available from us at our Web site, and in other media.  Users
+are free to download the software and build applications with it.
+<p>
+The 1.x versions of Berkeley DB were covered by the UC Berkeley copyright
+that covers software freely redistributable in source form.  When
+Sleepycat Software was formed, we needed to draft a license consistent
+with the copyright governing the existing, older software.  Because
+of important differences between the UC Berkeley copyright and the GPL,
+it was impossible for us to use the GPL.
+A second copyright, with
+terms contradictory to the first, simply would not have worked.
+<p>
+Sleepycat wanted to continue Open Source development of Berkeley DB
+for several reasons.
+We agree with Raymond <a href="#Raym98">[Raym98]</a> and others that Open
+Source software is typically of higher quality than proprietary,
+binary-only products.
+Our customers benefit from a community of developers who
+know and use Berkeley DB,
+and can help with application design,
+debugging,
+and performance tuning.
+Widespread distribution and use of the source code tends to
+isolate bugs early,
+and to get fixes back into the distributed system quickly.
+As a result,
+Berkeley DB is more reliable.
+Just as importantly,
+individual users are able to contribute new features
+and performance enhancements,
+to the benefit of everyone who uses Berkeley DB.
+From a business perspective,
+Open Source and free distribution of the
+software creates share for us, and gives us a market into which
+we can sell products and services.
+Finally, making the source code
+freely available reduces our support load, since customers can
+find and fix bugs without recourse to us, in many cases.
+<p>
+To preserve the Open Source heritage of the older Berkeley DB code,
+we drafted a new license governing the distribution of Berkeley DB
+2.x.  We adopted terms from the GPL that make it impossible to
+turn our Open Source code into proprietary code owned by someone else.
+<p>
+Briefly, the terms governing the use and distribution of Berkeley DB
+are:
+<ul>
+<li>
+your application must be internal to your site, or
+</li>
+<li>
+your application must be freely redistributable in source form, or
+</li>
+<li>
+you must get a license from us.
+</li>
+</ul>
+<p>
+For customers who prefer not to distribute Open Source products,
+we sell licenses to use and extend Berkeley DB at a reasonable cost.
+<p>
+We work hard to accommodate the needs of the Open Source community.
+For example,
+we have crafted special licensing arrangements with Gnome
+to encourage its use and distribution of Berkeley DB.
+<p>
+Berkeley DB conforms to the Open Source definition <a href="#Open99">[Open99]</a>.
+The license has
+been carefully crafted to keep the product available as an Open Source
+offering,
+while providing enough of a return on our investment to fund continued
+development and support of the product.  The current license has
+created a business capable of funding three years of development on
+the software that simply would not have happened otherwise.
+<h1>
+Summary
+</h1>
+<p>
+Berkeley DB offers a unique collection of features, targeted squarely
+at software developers who need simple, reliable database management
+services in their applications.  Good design and implementation and
+careful engineering throughout make the software better than many
+other systems.
+<p>
+Berkeley DB is an Open Source product, available at
+<a href="http://www.sleepycat.com">www.sleepycat.com</a>.
+for download.  The distributed system includes everything needed to
+build and deploy the software or to port it to new systems.
+<p>
+Sleepycat Software distributes Berkeley DB under a license agreement
+that draws on both the UC Berkeley copyright and the GPL.  The license
+guarantees that Berkeley DB will remain an Open Source product and
+provides Sleepycat with opportunities to make money to fund continued
+development on the software.

+<h1>Challenges in Embedded Database System Administration</h1>
+<h3>Margo Seltzer, Harvard University</h3>
+<h3>Michael Olson, Sleepycat Software, Inc.</h3>
+<em>{margo,mao}@sleepycat.com</em>
+</center>
+<p>
+Database configuration and maintenance have historically been complex tasks,
+often
+requiring expert knowledge of database design and application
+behavior.
+In an embedded environment, it is not feasible to require such
+expertise and ongoing database maintenance.
+This paper discusses the database administration
+challenges posed by embedded systems and describes how the
+Berkeley DB architecture addresses these challenges.
+
+<h2>1. Introduction</h2>
+
+Embedded systems provide a combination of opportunities and challenges
+in application and system configuration and management.
+As an embedded system is most often dedicated to a single application or
+small set of tasks, the operating conditions of the system are
+typically better understood than those of general purpose computing
+environments.
+Similarly, as embedded systems are dedicated to a small set of tasks,
+one would expect that the software to manage them should be small
+and simple.
+On the other hand, once an embedded system is deployed, it must
+continue to function without interruption and without administrator
+intervention.
+<p>
+Database administration consists of two components,
+initial configuration and ongoing maintenance.
+Initial configuration consists of database design, manifestation,
+and tuning.
+The instantiation of the design includes decomposing the design
+into tables, relations, or objects and designating proper indices
+and their implementations (e.g., Btrees, hash tables, etc.).
+Tuning a design requires selecting a location for the log and
+data files, selecting appropriate database page sizes, specifying
+the size of in-memory caches, and specifying the limits of 
+multi-threading and concurrency.
+As embedded systems define a specific environment and set of tasks,
+requiring expertise during the initial system
+configuration process is acceptable, and we focus our efforts on
+the ongoing maintenance of the system.
+In this way, our emphasis differs from other projects such as
+Microsoft's AutoAdmin project <a href="#Chaud982">[3]</a>, and the "no-knobs"
+administration that is identified as an area of important future
+research by the Asilomar authors<a href="#Bern98">[1]</a>.
+<p> 
+In this paper, we focus on what the authors
+of the Asilomar report call "gizmo" databases <a href="#Bern98"> [1]</a>,
+databases
+that reside in devices such as smart cards, toasters, or telephones.
+The key characteristics of such databases are that their
+functionality is completely transparent to users, no one ever
+performs explicit database operations or
+database maintenance, the database may crash at any time and
+must recover instantly, the device may undergo a hard reset at
+any time, requiring that the database return to its initial
+state, and the semantic integrity of the database must be maintained
+at all times.
+In Section 2, we provide more detail on the sorts of tasks
+typically performed by database administrators (DBAs) that must
+be automated in an embedded system.
+<p>
+The rest of this paper is structured as follows.
+In Section 2, we outline the requirements for embedded database support.
+In Section 3, we discuss how Berkeley DB
+is conducive to the hands-off management
+required in embedded systems.
+In Section 4, we discuss novel features that 
+enhance Berkeley
+DB's suitability for the embedded applications.
+In Section 5, we discuss issues of footprint size.
+In Section 6 we discuss related work, and we conclude
+in Section 7.
+
+<h2>2. Embedded Database Requirements</h2>
+Historically, much of the commercial database industry has been driven
+by the requirements of high performance online transaction
+processing (OLTP), complex query processing, and the industry
+standard benchmarks that have emerged (e.g., TPC-C <a href="#TPCC">[9]</a>,
+TPC-D <a href="#TPCD">[10]</a>) to
+allow for system comparisons.
+As embedded systems typically perform fairly simple queries,
+such metrics are not nearly as relevant for embedded database
+systems as are ease of maintenance, robustness, and small footprint.
+Of these three requirements, robustness and ease of maintenance
+are the key issues.
+Users must trust the data stored in their devices and must not need
+to manually perform anything resembling system administration in order
+to get their unit to work properly.
+Fortunately, ease of use and robustness are important side
+effects of simplicity and good design.
+These, in turn, lead to a small size, providing the third
+requirement of an embedded system.
+<h3>2.1 The User Perspective</h3>
+<p>
+In the embedded database arena, it is the ongoing maintenance tasks
+that must be automated, not necessarily the initial system configuration.
+There are five tasks
+that are traditionally performed by DBAs,
+but must be performed automatically
+in embedded database systems.
+These tasks are
+log archival and reclamation,
+backup,
+data compaction/reorganization,
+automatic and rapid recovery, and
+reinitialization from scratch.
+<P>
+Log archival and backup are tightly coupled.
+Database backups are part of any
+large database installation, and log archival is analogous to incremental
+backup.
+It is not clear what the implications of backup and archival are in
+an embedded system.
+Consumers do not back up their VCRs or refrigerators, yet they do
+(or should) back up their personal computers or personal digital
+assistants.
+For the remainder of this paper, we assume that backups, in some form,
+are required for gizmo databases (imagine having to reprogram, manually,
+the television viewing access pattern learned by some set-top television
+systems today).
+Furthermore, we require that those backups are nearly instantaneous or
+completely transparent,
+as users should not be aware that their gizmos are being backed up
+and should not have to explicitly initiate such backups.
+<p>
+Data compaction or reorganization has traditionally required periodic
+dumping and restoration of
+database tables and the recreation of indices.
+In an embedded system, such reorganization must happen automatically.
+<p>
+Recovery issues are similar in embedded and traditional environments
+with a few exceptions.
+While a few seconds or even a minute recovery is acceptable
+for a large server installation, no one is willing to wait
+for their telephone or television to reboot.
+As with archival, recovery must be nearly instantaneous in an embedded product.
+Secondly, it is often the case that a system will be completely
+reinitialized, rather than simply rebooted.
+In this case, the embedded database must be restored to its initial
+state, freeing all its resources.
+This is not typically a requirement of large server systems.
+<h3>2.2 The Developer Perspective</h3>
+<p>
+In addition to the maintenance-free operation required of the
+embedded systems, there are a number of requirements that fall
+out of the constrained resources typically found in the "gizmos"
+using gizmo databases. These requirements are:
+small footprint,
+short code-path,
+programmatic interface for tight application coupling and
+to avoid the overhead (in both time and size) of 
+interfaces such as SQL and ODBC,
+application configurability and flexibility,
+support for complete memory-resident operation (e.g., these systems
+must run on gizmos without file systems), and
+support for multi-threading.
+<p>
+A small footprint and short code-path are self-explanatory, however
+what is not as obvious is that the programmatic interface requirement
+is the logical result of them.
+Traditional interfaces such as ODBC and SQL add significant
+size overhead and frequently add multiple context/thread switches
+per operation, not to mention several IPC calls.
+An embedded product is less likely to require the complex
+query processing that SQL enables.
+Instead, in the embedded space, the ability for an application
+to configure the database for the specific tasks in question
+is more important than a general query interface.
+<p>
+As some systems do not provide storage other than RAM and ROM,
+it is essential that an embedded database work seemlessly
+in memory-only environments.
+Similarly, many of today's embedded operating systems provide a
+single address space architecture, so a simple, multi-threaded
+capability is essential for application requiring any concurrency.
+<p>
+In general, embedded applications run on gizmos whose native
+operating system support varies tremendously.
+For example, the embedded OS may or may
+not support user-level processing or multi-threading.
+Even if it does, a particular embedded
+application may or may not need it.
+Not all applications need more than one thread of control.
+An embedded database must provide mechanisms to developers
+without deciding policy.
+For example, the threading model in an application is a matter of policy,
+and depends
+not on the database software, but on the hardware, operating
+system, and the application's feature set.
+Therefore, the data manager must provide for the use of multi-threading,
+but not require it.
+
+<h2>3. Berkeley DB: A Database for Embedded Systems</h2>
+Berkeley DB is the result of implementing database functionality 
+using the UNIX tool-based philosophy.
+The current Berkeley DB package, as distributed by Sleepycat
+Software, is a descendant of the hash and btree access methods
+distributed with 4.4BSD and its descendents.
+The original package (referred to as DB-1.85),
+while intended as a public domain replacement for dbm and
+its followers (e.g., ndbm, gdbm, etc), rapidly became widely
+used as an efficient, easy-to-use data store. 
+It was incorporated into a number of Open Source packages including
+Perl, Sendmail, Kerberos, and the GNU C-library.
+<p>
+Versions 2.X and higher are distributed by Sleepycat Software and
+add functionality for concurrency, logging, transactions, and
+recovery.
+Each piece of additional functionality is implemented as an independent
+module, which means that the subsystems can be used outside the
+context of Berkeley DB.  For example, the locking subsystem can
+easily be used to implement locking for a non-DB application and
+the shared memory buffer pool can be used for any application
+caching data in main memory.
+This subsystem design allows a designer to pick and choose
+the functionality necessary for the application, minimizing
+memory footprint and maximizing performance.
+This addresses the small footprint and short code-path criteria
+mentioned in the previous section.
+<p>
+As Berkeley DB grew out of a replacement for dbm, its primary
+implementation language has always been C and its interface has
+been programmatic.  The C interface is the native interface,
+unlike many database systems where the programmatic API is simply
+a layer on top of an already-costly query interface (e.g. embedded
+SQL).
+Berkeley DB's heritage is also apparent in its data model; it has
+none.
+The database stores unstructured key/data pairs, specified as
+variable length byte strings.
+This leaves schema design and representation issues the responsibility
+of the application, which is ideal for an embedded environment.
+Applications retain full control over specification of their data
+types, representation, index values, and index relationships.
+In other words, Berkeley DB provides a robust, high-performance,
+keyed storage system, not a particular database management system.
+We have designed for simplicity and performance, trading off
+complex, general purpose support that is better encapsulated in
+applications.
+<p>
+Another element of Berkeley DB's programmatic interface is its
+customizability; applications can specify Btree comparison and
+prefix compression functions, hash functions, error routines,
+and recovery models.
+This means that embedded applications can tailor the underlying
+database to best suit their data demands.
+Similarly, the utilities traditionally bundled with a database
+manager (e.g., recovery, dump/restore, archive) are implemented
+as tiny wrapper programs around library routines.  This means
+that it is not necessary to run separate applications for the
+utilities.  Instead, independent threads can act as utility
+daemons, or regular query threads can perform utility functions.
+Many of the current products built on Berkeley DB are bundled as
+a single large server with independent threads that perform functions
+such as checkpoint, deadlock detection, and performance monitoring.
+<p>
+As mentioned earlier, living in an embedded environment requires
+flexible management of storage.
+Berkeley DB does not require any preallocation of disk space
+for log or data files.
+While many commercial database systems take complete control
+of a raw device, Berkeley DB uses a normal file system, and
+can therefore, safely and easily share a data space with other
+programs.
+All databases and log files are native files of the host environment,
+so whatever utilities are provided by the environment can be used
+to manage database files as well.
+<p>
+Berkeley DB provides three different memory models for its
+management of shared information.
+Applications can use the IEEE Std 1003.1b-1993 (POSIX) <tt>mmap</tt>
+interface to share
+data, they can use system shared memory, as frequently provided
+by the shmget family of interfaces, or they can use per-process
+heap memory (e.g., malloc).
+Applications that require no permanent storage and do not provide
+shared memory facilities can still use Berkeley DB by requesting
+strictly private memory and specifying that all databases be
+memory-resident.
+This provides pure-memory operation.
+<p>
+Lastly, Berkeley DB is designed for rapid startup -- recovery can
+happen automatically as part of system initialization.
+This means that Berkeley DB works correctly in environments where
+gizmos are suddenly shut down and restarted.
+
+<h2>4. Extensions for Embedded Environments </h2>
+While the Berkeley DB library has been designed for use in
+embedded systems, all the features described above are useful
+in more conventional systems as well.
+In this section, we discuss a number of features and "automatic
+knobs" that are specifically geared
+toward the more constrained environments found in gizmo databases.
+
+<h3>4.1 Automatic compression</h3>
+Following the programmatic interface design philosophy, we 
+support application-specific (or default) compression routines.
+These can be geared toward the particular data types present
+in the application's dataset, thus providing better compression
+than a general purpose routine.
+Note that the application could instead specify an encryption
+function and create encrypted databases instead of compressed ones.
+Alternately, the application might specify a function that performs
+both compression and encryption.
+<p>
+As applications are also permitted to specify comparison and hash
+functions, the application can chose to organize its data based
+either on uncompressed and clear-text data or compressed and encrypted
+data.
+If the application indicates that data should be compared in its
+processed form (i.e., compressed and encrypted), then the compression
+and encryption are performed on individual data items and the in-memory
+representation retains these characteristics.
+However, if the application indicates that data should be compared in
+its original form, then entire pages are transformed upon being read
+into or written out of the main memory buffer cache.
+These two alternatives provide the flexibility to trade space
+and security for performance.
+
+<h3>4.2 In-memory logging & transactions</h3>
+One of the four key properties of transaction systems is durability.
+This means that transaction systems are designed for permanent storage
+(most commonly disk).  However, as mentioned above, embedded systems
+do not necessarily contain any such storage.
+Nevertheless, transactions can be useful in this environment to
+preserve the semantic integrity of the underlying storage.
+Berkeley DB optionally provides logging functionality and
+transaction support regardless of whether the database and logs
+are on disk or in memory.
+
+<h3>4.3 Remote Logs</h3>
+While we do not expect users to backup their television sets and
+toasters, it is conceivable that a set-top box provided by a
+cable carrier should, in fact, be backed up by that cable carrier.
+The ability to store logs remotely can provide "information appliance"
+functionality, and can also be used in conjunction with local logs
+to enhance reliability.
+Furthermore, remote logs provide for catastrophic recovery, e.g., loss
+of the gizmo, destruction of the gizmo, etc.
+
+<h3>4.4 Application References to Database Buffers</h3>
+
+Typically, when data is returned to the user, it must be copied
+from the data manager's buffer cache (or data page) into the
+application's memory.
+However, in an embedded environment, the robustness of the
+total software package is of paramount importance, not the
+isolation between the application and the data manager.
+As a result, it is possible for the data manager to avoid
+copies by giving applications direct references to data items
+in a shared memory cache.
+This is a significant performance optimization that can be
+allowed when the application and data manager are tightly
+integrated.
+
+<h3>4.5 Recoverable database creation/deletion</h3>
+
+In a conventional database management system, the creation of
+database tables (relations) and indices are heavyweight operations
+that are not recoverable.
+This is not acceptable in a complex embedded environment where
+instantaneous recovery and robust operation in the face of
+all types of database operations is essential.
+While Berkeley DB files can be removed using normal file system
+utilities, we provide transaction protected utilities that
+allow us to recover both database creation and deletion.
+
+<h3>4.6 Adaptive concurrency control</h3>
+The Berkeley DB package uses page-level locking by default.
+This trades off fine grain concurrency control for simplicity
+during recovery. (Finer grain concurrency control can be
+obtained by reducing the page size in the database.)
+However, when multiple threads/processes perform page-locking
+in the presence of writing operations, there is the
+potential for deadlock.
+As some environments do not need or desire the overhead of
+logging and transactions, it is important to provide the
+ability for concurrent access without the potential for
+deadlock.
+<p>
+Berkeley DB provides an option to perform coarser grain,
+deadlock-free locking.
+Rather than locking on pages, locking is performed at the
+interface to the database.
+Multiple readers or a single writer are allowed to be
+active in the database at any instant in time, with
+conflicting requests queued automatically.
+The presence of cursors, through which applications can both
+read and write data, complicates this design.
+If a cursor is currently being used for reading, but will later
+be used to write, the system will be deadlock prone if no
+special precautions are taken.
+To handle this situation, we require that, when a cursor is
+created, the application specify any future intention to write.
+If there is an intention to write, the cursor is granted an
+intention-to-write lock which does not conflict with readers,
+but does conflict with other intention-to-write locks and write
+locks.
+The end result is that the application is limited to a single
+potentially writing cursor accessing the database at any point
+in time.
+<p>
+Under periods of low contention (but potentially high throughput),
+the normal page-level locking provides the best overall throughput.
+However, as contention rises, so does the potential for deadlock.
+As some cross-over point, switching to the less concurrent, but
+deadlock-free locking protocol will result in higher throughput
+as operations must never be retried.
+Given the operating conditions of an embedded database manager,
+it is useful to make this change automatically as the system
+itself detects high contention.
+
+<h3>4.7 Adaptive synchronization</h3>
+
+In addition to the logical locks that protect the integrity of the
+database pages, Berkeley DB must synchronize access to shared memory
+data structures, such as the lock table, in-memory buffer pool, and
+in-memory log buffer.
+Each independent module uses a single mutex to protect its shared
+data structures, under the assumption that operations that require
+the mutex are very short and the potential for conflict is
+low.
+Unfortunately, in highly concurrent environments with multiple processors
+present, this assumption is not always true.
+When this assumption becomes invalid (that is, we observe significant
+contention for the subsystem mutexes), we can switch over to a finer-grained
+concurrency model for the mutexes.
+Once again, there is a performance trade-off.  Fine-grain mutexes
+impose a penalty of approximately 25% (due to the increased number
+of mutexes required for each operation), but allow for higher throughput.
+Using fine-grain mutexes under low contention would cause a decrease
+in performance, so it is important to monitor the system carefully,
+so that the change can be executed only when it will increase system
+throughput without jeopardizing latency.
+
+<h2>5. Footprint of an Embedded System</h2>
+While traditional systems compete on price-performance, the
+embedded players will compete on price, features, and footprint.
+The earlier sections have focused on features; in this section
+we focus on footprint.
+<p>
+Oracle reports that Oracle Lite 3.0 requires 350 KB to 750 KB
+of memory and approximately 2.5 MB of hard disk space <a href="#Oracle">[7]</a>.
+This includes drivers for interfaces such as ODBC and JDBC.
+In contrast, Berkeley DB ranges in size from 75 KB to under 200 KB,
+foregoing heavyweight interfaces such as ODBC and JDBC and
+providing a variety of deployed sizes that can be used depending
+on application needs.  At the low end, applications requiring
+a simple single-user access method can choose from either extended
+linear hashing, B+ trees, or record-number based retrieval and
+pay only the 75 KB space requirement.
+Applications requiring all three access methods will observe the
+110 KB footprint.
+At the high end, a fully recoverable, high-performance system
+occupies less than a quarter megabyte of memory.
+This is a system you can easily incorporate in your toaster oven.
+Table 1 shows the per-module break down of the entire Berkeley DB
+library.  Note that this does not include memory used to cache database
+pages.

+<h2>6. Related Work</h2>
+
+Every three to five years, leading researchers in the database
+community convene to identify future directions in database
+research.
+They produce a report of this meeting, named for the year and
+location of the meeting.
+The most recent of these reports, the 1998 Asilomar report,
+identifies the embedded database market as one of the
+high growth areas in database research <a href="#Bern98">[1]</a>.
+Not surprisingly, market analysts identify the embedded database
+market as a high-growth area in the commercial sector as well <a href="#Host98">
+[5]</a>.
+<p>
+The Asilomar report identifies a new class of database applications, which they
+term "gizmo" databases, small databases embedded in tiny mobile
+appliances, e.g., smart-cards, telephones, personal digital assistants.
+Such databases must be self-managing, secure and reliable.
+Thus, the idea is that gizmo databases require plug and play data
+management with no database administrator (DBA), no human settable
+parameters, and the ability to adapt to changing conditions.
+More specifically, the Asilomar authors claim that the goal is
+self-tuning, including defining the physical DB design, the
+logical DB design, and automatic reports and utilities <a href="#Bern98">[1]</a>
+To date,
+few researchers have accepted this challenge, and there is a dearth
+of research literature on the subject.
+<p>
+Our approach to embedded database administration is fundamentally
+different than that described by the Asilomar authors.
+We adopt their terminology, but view the challenge in supporting
+gizmo databases to be that of self-sustenance <em>after</em> initial
+deployment.  Therefore, we find it, not only acceptable, but
+desirable to assume that application developers control initial
+database design and configuration.  To the best of our knowledge,
+none of the published work in this area addresses this approach.
+<p>
+As the research community has not provided guidance in this
+arena, most work in embedded database administration has fallen
+to the commercial vendors.
+These vendors fall into two camps, companies selling databases
+specifically designed for embedding or programmatic access
+and the major database vendors (e.g., Oracle, Informix, Sybase).
+<p>
+The embedded vendors all acknowledge the need for automatic
+administration, but fail to identify precisely how their
+products actually accomplish this.
+A notable exception is Interbase whose white paper
+comparison with Sybase and Microsoft's SQL servers
+explicitly address features of maintenance ease.
+Interbase claims that as they use no log files, there is
+no need for log reclamation, checkpoint tuning, or other
+tasks associated with log management.  However, Interbase
+uses Transaction Information Pages, and it is unclear
+how these are reused or reclaimed <a href="#Interbase">[6]</a>.
+Additionally, with a log-free system, they must use
+a FORCE policy (write all pages to disk at commit),
+as defined by Haerder and Reuter <a href="#Haerder">[4]</a>.  This has
+serious performance consequences for disk-based systems.
+The approach described in this paper does use logs and
+therefore requires log reclamation,
+but provides hooks so the application may reclaim logs
+safely and programmatically.
+While Berkeley DB does require checkpoints, the goal of
+tuning the checkpoint interval is to bound recovery time.
+Since the checkpoint interval in Berkeley DB can be expressed
+by the amount of log data written, it requires no tuning.
+The application designer sets a target recovery time, and
+selects the amount of log data that can be read in that interval
+and specifies the checkpoint interval appropriately.  Even as
+load changes, the time to recover does not.
+<p>
+The backup approaches taken by Interbase and Berkeley DB
+are similar in that they both allow online backup, but
+rather different in their affect on transactions running
+during backup.  As Interbase performs backups as transactions
+<a href="#Interbase">[6]</a>, concurrent queries can suffer potentially long
+delays.  Berkeley DB uses native operating system system utilities
+and recovery for backups, so there is no interference with
+concurrent activity, other than potential contention on disk
+arms.
+<p>
+There are a number of database vendors selling in
+the embedded market (e.g., Raima, 
+Centura, Pervasive, Faircom), but none highlight
+the special requirements of embedded database
+applications.
+On the other end of the spectrum, the major vendors,
+Oracle, Sybase, Microsoft, are all becoming convinced
+of the importance of the embedded market.
+As mentioned earlier, Oracle has announced its
+Oracle Lite server for embedded use.
+Sybase has announced its UltraLite platform for "application-optimized,
+high-performance, SQL database engine for professional
+application developers building solutions for mobile and embedded platforms."
+<a href="#Sybase">[8]</a>.
+We believe that SQL is incompatible with the
+gizmo database environment or truly embedded systems for which Berkeley
+DB is most suitable.
+Microsoft research is taking a different approach, developing
+technology to assist in automating initial database design and
+index specification <a href="#Chaud98">[2]</a><a href="#Chaud982">[3]</a>.
+As mentioned earlier, we believe that such configuration is, not only
+acceptable in the embedded market, but desirable so that applications
+can tune their database management for the target environment.
+<h2>7. Conclusions</h2>
+The coming wave of embedded systems poses a new set of challenges
+for data management.
+The traditional server-based, big footprint systems designed for
+high performance on big iron are not the right approach in this
+environment.
+Instead, application developers need small, fast, versatile systems
+that can be tailored to a specific environment.
+In this paper, we have identified several of the key issues in
+providing these systems and shown how Berkeley DB provides
+many of the characteristics necessary for such applications.

+<h1 align=center>Client program</h1>
+<p>Changing a Berkeley DB application to remotely call a server program requires
+only a few changes on the client side:
+<p><ol>
+<p><li>The client application must create and use a Berkeley DB environment,
+that is, it cannot simply call the <a href="../../api_c/db_create.html">db_create</a> interface, but must
+first call the <a href="../../api_c/env_create.html">db_env_create</a> interface to create an environment in
+which the database will live.
+<p><li>The client application must call <a href="../../api_c/env_create.html">db_env_create</a> using the
+<a href="../../api_c/env_create.html#DB_CLIENT">DB_CLIENT</a> flag.
+<p><li>The client application must call the additional DB_ENV
+method <a href="../../api_c/env_set_server.html">DBENV-&gt;set_server</a> to specify the database server.  This call
+must be made before opening the environment with the <a href="../../api_c/env_open.html">DBENV-&gt;open</a>
+call.
+</ol>
+<p>The client application provides three pieces of information to Berkeley DB as
+part of the <a href="../../api_c/env_set_server.html">DBENV-&gt;set_server</a> call:
+<p><ol>
+<p><li>The hostname of the server.  The hostname format is not
+specified by Berkeley DB, but must be in a format acceptable to the local
+network support, specifically, the RPC clnt_create interface.
+<p><li>The client timeout.  This is the number of seconds the client
+will wait for the server to respond to its requests.  A default is used
+if this value is zero.
+<p><li>The server timeout.  This is the number of seconds the server
+will allow client resources to remain idle before releasing those
+resources.  The resources this applies to are transactions and cursors,
+as those objects hold locks and if a client dies, the server needs to
+release those resources in a timely manner.  This value
+is really a hint to the server, as the server may choose to override this
+value with its own.
+</ol>
+<p>The only other item of interest to the client is the home directory
+that is given to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> call.
+The server is started with a list of allowed home directories.
+The client must use one of those names (where a name is the last
+component of the home directory).  This allows the pathname structure
+on the server to change without client applications needing to be
+aware of it.
+<p>Once the <a href="../../api_c/env_set_server.html">DBENV-&gt;set_server</a> call has been made, the client is
+connected to the server and all subsequent Berkeley DB
+operations will be forwarded to the server.  The client does not need to
+be otherwise aware that it is using a database server rather than
+accessing the database locally.
+<p>It is important to realize that the client portion of the Berkeley DB library
+acts as a simple conduit, forwarding Berkeley DB interface arguments to the
+server without interpretation.  This has two important implications.
+First, all pathnames must be specified relative to the server.  For
+example, the home directory and other configuration information passed by
+the application when creating its environment or databases must be
+pathnames for the server, not the client system.  In addition, as there
+is no logical bundling of operations at the server, performance is usually
+significantly less than when Berkeley DB is embedded within the client's address
+space, even if the RPC is to a local address.

+<h1 align=center>Introduction</h1>
+<p>Berkeley DB includes a basic implementation of a client-server protocol, using
+Sun Microsystem's Remote Procedure Call Protocol.  RPC support is only
+available for UNIX systems, and is not included in the Berkeley DB library by
+default, but must be enabled during configuration.  See
+<a href="../../ref/build_unix/conf.html">Configuring Berkeley DB</a> for more
+information.  For more information on RPC itself, see your UNIX system
+documentation or <i>RPC: Remote Procedure Call Protocol
+Specification, RFC1832, Sun Microsystems, Inc., USC-ISI</i>.
+<p>Only some of the complete Berkeley DB functionality is available when using RPC.
+The following functionality is available:
+<p><ol>
+<li>The <a href="../../api_c/env_create.html">db_env_create</a> interface and the DB_ENV
+handle methods.
+<li>The <a href="../../api_c/db_create.html">db_create</a> interface and the DB handle
+methods.
+<li>The <a href="../../api_c/txn_begin.html">txn_begin</a>, <a href="../../api_c/txn_commit.html">txn_commit</a> and
+<a href="../../api_c/txn_abort.html">txn_abort</a> interfaces.
+</ol>
+<p>The RPC client/server code does not support any of the user-defined
+comparison or allocation functions, e.g., an application using the RPC
+support may not specify its own Btree comparison function.  If your
+application only requires those portions of Berkeley DB, then using RPC is
+fairly simple.  If your application requires other Berkeley DB functionality,
+such as direct access to locking, logging or shared memory buffer memory
+pools, then your application cannot use the RPC support.
+<p><b>The Berkeley DB RPC support does not provide any security or authentication of
+any kind.</b>  Sites needing any kind of data security measures must modify
+the client and server code to provide whatever level of security they
+require.
+<p>One particularly interesting use of the RPC support is for debugging Berkeley DB
+applications.  The seamless nature of the interface means that with very
+minor application code changes, an application can run outside of the
+Berkeley DB address space, making it far easier to track down many types of
+errors such as memory misuse.
+<p>Using the RPC mechanisms in Berkeley DB involves two basic steps:
+<p><ol>
+<p><li>Modify your Berkeley DB application to act as a client and call the
+RPC server.
+<li>Run the <a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a> server program on the system
+where the database resides.
+</ol>

+<h1 align=center>Server program</h1>
+<p>The Berkeley DB server utility, <a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a>, handles all of the
+client application requests.
+<p>Currently, the <a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a> utility is single-threaded,
+limiting the number of requests that it can handle.  Modifying the server
+implementation to run in multi-thread or multi-process mode will require
+modification of the server code automatically generated by the rpcgen
+program.
+<p>There are two different types of timeouts used by <a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a>.
+The first timeout (which can be modified within some constraints by the
+client application), is the resource timeout.  When clients use
+transactions or cursors, those resources hold locks in Berkeley DB across calls
+to the server.  If a client application dies or loses its connection to
+the server while holding those resources, it prevents any other client
+from acquiring them.  Therefore, it is important to detect that a client
+has not used a resource for some period of time and release them.  In the
+case of transactions, the server aborts the transaction.  In the case of
+cursors, the server closes the cursor.
+<p>The second timeout is an idle timeout.  A client application may remain
+idle with an open handle to an environment and a database.  Doing so
+simply consumes some memory, it does not hold locks.  However, the Berkeley DB
+server may want to eventually reclaim resources if a client dies or
+remains disconnected for a long period of time, so there is a separate
+idle timeout for open Berkeley DB handles.
+<p>The list of home directories specified to <a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a> are the
+only ones client applications are allowed to use.  When
+<a href="../../utility/berkeley_db_svc.html">berkeley_db_svc</a> is started, it is given a list of pathnames.
+Clients are expected to specify the name of the home directory (defined
+as the last component in the directory pathname) as the database
+environment they are opening.  In this manner, clients need only know the
+name of their home environment, and not its full pathname on the server
+machine.  This means, of course, that only one environment of a particular
+name is allowed on the server at any given time.

+a later version of Berkeley DB. For more information on using Berkeley DB with
+Sendmail, please review the README and src/README files in the Sendmail
+distribution.
+<p>To load sendmail against Berkeley DB, add the following lines to
+BuildTools/Site/site.config.m4:
+<p><blockquote><pre>APPENDDEF(`confINCDIRS', `-I/usr/local/BerkeleyDB/include')
+APPENDDEF(`confLIBDIRS', `-L/usr/local/BerkeleyDB/lib')</pre></blockquote>
+<p>where those are the paths to #include &lt;db.h&gt; and libdb.a respectively.
+Then, run "Build -c" from the src directory.

+<h1 align=center>Closing a database</h1>
+<p>The only other operation that we need for our simple example is closing
+the database, and cleaning up the DB handle.
+<p>It is necessary that the database be closed. The most important reason
+for this is that Berkeley DB runs on top of an underlying buffer cache.  If
+the modified database pages are never explicitly flushed to disk and
+the database is never closed, changes made to the database may never
+make it out to disk, because they are held in the Berkeley DB cache.  As the
+default behavior of the close function is to flush the Berkeley DB cache,
+closing the database will update the on-disk information.
+<p>The <a href="../../api_c/db_close.html">DB-&gt;close</a> interface takes two arguments:
+<p><dl compact>
+<p><dt>db<dd>The database handle returned by <a href="../../api_c/db_create.html">db_create</a>.

+<h1 align=center>Removing elements from a database</h1>
+<p>The simplest way to remove elements from a database is the <a href="../../api_c/db_del.html">DB-&gt;del</a>
+interface.
+<p>The <a href="../../api_c/db_del.html">DB-&gt;del</a> interface takes four of the same five arguments that
+the <a href="../../api_c/db_get.html">DB-&gt;get</a> and <a href="../../api_c/db_put.html">DB-&gt;put</a> interfaces take.  The difference
+is that there is no need to specify a data item, as the delete operation
+is only interested in the key that you want to remove.
+<p><dl compact>
+<p><dt>db<dd>The database handle returned by <a href="../../api_c/db_create.html">db_create</a>.
+<p><dt>txnid<dd>A transaction ID.
+In our simple case, we aren't expecting to recover the database after
+application or system crash, so we aren't using transactions, and will
+leave this argument unspecified.
+<p><dt>key<dd>The key item for the key/data pair that we want to delete from the
+database.
+<p><dt>flags<dd>Optional flags modifying the underlying behavior of the <a href="../../api_c/db_del.html">DB-&gt;del</a>
+interface.  There are currently no available flags for this interface,
+so the flags argument should always be set to 0.
+</dl>
+<p>Here's what the code to call <a href="../../api_c/db_del.html">DB-&gt;del</a> looks like:
+<p><blockquote><pre>#include &lt;sys/types.h&gt;
+#include &lt;stdio.h&gt;
+#include &lt;db.h&gt;
+<p>
+#define	DATABASE "access.db"
+<p>
+int
+main()
+{
+	DB *dbp;
+	DBT key, data;
+	int ret;
+<p>
+	if ((ret = db_create(&dbp, NULL, 0)) != 0) {
+		fprintf(stderr, "db_create: %s\n", db_strerror(ret));
+		exit (1);
+	}
+	if ((ret = dbp-&gt;open(
+	    dbp, DATABASE, NULL, DB_BTREE, DB_CREATE, 0664)) != 0) {
+		dbp-&gt;err(dbp, ret, "%s", DATABASE);
+		goto err;
+	}
+<p>
+	memset(&key, 0, sizeof(key));
+	memset(&data, 0, sizeof(data));
+	key.data = "fruit";
+	key.size = sizeof("fruit");
+	data.data = "apple";
+	data.size = sizeof("apple");
+<p>
+	if ((ret = dbp-&gt;put(dbp, NULL, &key, &data, 0)) == 0)
+		printf("db: %s: key stored.\n", (char *)key.data);
+	else {
+		dbp-&gt;err(dbp, ret, "DB-&gt;put");
+		goto err;
+	}
+<p>
+	if ((ret = dbp-&gt;get(dbp, NULL, &key, &data, 0)) == 0)
+		printf("db: %s: key retrieved: data was %s.\n",
+		    (char *)key.data, (char *)data.data);
+	else {
+		dbp-&gt;err(dbp, ret, "DB-&gt;get");

+	}
+<p><b>	if ((ret = dbp-&gt;del(dbp, NULL, &key, 0)) == 0)

+	else {
+		dbp-&gt;err(dbp, ret, "DB-&gt;del");
+		goto err;
+	}
+</b></pre></blockquote>
+<p>After the <a href="../../api_c/db_del.html">DB-&gt;del</a> call returns, the entry referenced by the key
+fruit has been removed from the database.

+<h1 align=center>Error returns</h1>
+<p>The Berkeley DB interfaces always return a value of 0 on success.  If the
+operation does not succeed for any reason, the return value will be
+non-zero.
+<p>If a system error occurred (e.g., Berkeley DB ran out of disk space, or
+permission to access a file was denied, or an illegal argument was
+specified to one of the interfaces), Berkeley DB returns an <b>errno</b>
+value.  All of the possible values of <b>errno</b> are greater than
+0.
+<p>If the operation didn't fail due to a system error, but wasn't
+successful either, Berkeley DB returns a special error value.  For example,
+if you tried to retrieve the data item associated with the key
+<b>fruit</b>, and there was no such key/data pair in the database,
+Berkeley DB would return <a href="../../ref/program/errorret.html#DB_NOTFOUND">DB_NOTFOUND</a>, a special error value that means
+the requested key does not appear in the database.  All of the possible
+special error values are less than 0.
+<p>Berkeley DB also offers programmatic support for displaying error return values.
+First, the <a href="../../api_c/env_strerror.html">db_strerror</a> interface returns a pointer to the error
+message corresponding to any Berkeley DB error return, similar to the ANSI C
+strerror interface, but is able to handle both system error returns and
+Berkeley DB-specific return values.
+<p>Second, there are two error functions, <a href="../../api_c/db_err.html">DB-&gt;err</a> and <a href="../../api_c/db_err.html">DB-&gt;errx</a>.
+These functions work like the ANSI C printf interface, taking a
+printf-style format string and argument list, and optionally appending
+the standard error string to a message constructed from the format string
+and other arguments.

+<p>The programming concepts are:
+<ul type=disc>
+<li><a href="keydata.html">Key/data pairs</a>
+<li><a href="handles.html">Object handles</a>
+<li><a href="errors.html">Error returns</a>
+</ul>
+<p>This database application will:
+<ul type=disc>
+<li><a href="open.html">Create a simple database</a>
+<li><a href="put.html">Store items</a>
+<li><a href="get.html">Retrieve items</a>
+<li><a href="del.html">Remove items</a>
+<li><a href="close.html">Close the database</a>
+</ul>
+<p>The introduction will be presented using the programming language C.  The
+<a href="example.txt">complete source</a> of the final version of the
+example program is included in the Berkeley DB distribution.

+<h1 align=center>Key/data pairs</h1>
+<p>Berkeley DB uses key/data pairs to identify elements in the database.
+That is, in the general case, whenever you call a Berkeley DB interface,
+you present a key to identify the key/data pair on which you intend
+to operate.
+<p>For example, you might store some key/data pairs as follows:
+<p><table border=1>
+<tr><th>Key:</th><th>Data:</th></tr>
+<tr><td>fruit</td><td>apple</td></tr>
+<tr><td>sport</td><td>cricket</td></tr>
+<tr><td>drink</td><td>water</td></tr>
+</table>
+<p>In each case, the first element of the pair is the key, and the second is
+the data.  To store the first of these key/data pairs into the database,
+you would call the Berkeley DB interface to store items, with <b>fruit</b> as
+the key, and <b>apple</b> as the data.  At some future time, you could
+then retrieve the data item associated with <b>fruit</b>, and the Berkeley DB
+retrieval interface would return <b>apple</b> to you.  While there are
+many variations and some subtleties, all accesses to data in Berkeley DB come
+down to key/data pairs.
+<p>Both key and data items are stored in simple structures (called
+<a href="../../api_c/dbt.html">DBT</a>s) that contain a reference to memory and a length, counted
+in bytes.  (The name <a href="../../api_c/dbt.html">DBT</a> is an acronym for <i>database
+thang</i>, chosen because nobody could think of a sensible name that wasn't
+already in use somewhere else.)  Key and data items can be arbitrary
+binary data of practically any length, including 0 bytes.  There is a
+single data item for each key item, by default, but databases can be
+configured to support multiple data items for each key item.

+<p>
+<h1 align=center>Opening a database</h1>
+<p>Opening a database is done in two steps: first, a DB handle is
+created using the Berkeley DB <a href="../../api_c/db_create.html">db_create</a> interface, and then the
+actual database is opened using the <a href="../../api_c/db_open.html">DB-&gt;open</a> function.
+<p>The <a href="../../api_c/db_create.html">db_create</a> interface takes three arguments:
+<p><dl compact>
+<p><dt>dbp<dd>A location to store a reference to the created structure.
+<p><dt>environment<dd>A location to specify an enclosing Berkeley DB environment, not used in our
+example.
+<p><dt>flags<dd>A placeholder for flags, not used in our example.
+</dl>
+<p>The <a href="../../api_c/db_open.html">DB-&gt;open</a> interface takes five arguments:
+<p><dl compact>
+<p><dt>file<dd>The name of the database file to be opened.
+<p><dt>database<dd>The optional database name, not used in this example.
+<p><dt>type<dd>The type of database to open.  This value will be one of the four access
+methods Berkeley DB supports:  DB_BTREE, DB_HASH, DB_QUEUE or DB_RECNO, or the
+special value DB_UNKNOWN, which allows you to open an existing file
+without knowing its type.
+<p><dt>flags<dd>Various flags that modify the behavior of <a href="../../api_c/db_open.html">DB-&gt;open</a>.  In our
+simple case, the only interesting flag is <a href="../../api_c/env_open.html#DB_CREATE">DB_CREATE</a>.  This flag
+behaves similarly to the IEEE/ANSI Std 1003.1 (POSIX) O_CREATE flag to the open system
+call, causing Berkeley DB to create the underlying database if it does not
+yet exist.
+<p><dt>mode<dd>The file mode of any underlying files that <a href="../../api_c/db_open.html">DB-&gt;open</a> will create.
+The mode behaves as does the IEEE/ANSI Std 1003.1 (POSIX) mode argument to the open
+system call, and specifies file read, write and execute permissions.
+Of course, only the read and write permissions are relevant to Berkeley DB.
+</dl>
+<p>Here's what the code to create the handle and then call <a href="../../api_c/db_open.html">DB-&gt;open</a>
+looks like:
+<p><blockquote><pre><b>#include &lt;sys/types.h&gt;
+#include &lt;stdio.h&gt;
+#include &lt;db.h&gt;
+<p>
+#define	DATABASE "access.db"
+<p>
+int
+main()
+{
+	DB *dbp;
+	int ret;
+<p>
+	if ((ret = db_create(&dbp, NULL, 0)) != 0) {
+		fprintf(stderr, "db_create: %s\n", db_strerror(ret));
+		exit (1);
+	}
+	if ((ret = dbp-&gt;open(
+	    dbp, DATABASE, NULL, DB_BTREE, DB_CREATE, 0664)) != 0) {
+		dbp-&gt;err(dbp, ret, "%s", DATABASE);
+		goto err;
+	}</b>
+</pre></blockquote>
+<p>If the call to <a href="../../api_c/db_create.html">db_create</a> is successful, the variable <b>dbp</b>
+will contain a database handle that will be used to configure and access
+an underlying database.
+<p>As you see, the program opens a database named <b>access.db</b>.  The
+underlying database is a Btree.  Because the <a href="../../api_c/env_open.html#DB_CREATE">DB_CREATE</a> flag was
+specified, the file will be created if it does not already exist.  The
+mode of any created files will be 0664 (i.e., readable and writeable by
+the owner and the group, and readable by everyone else).
+<p>One additional function call is used in this code sample, <a href="../../api_c/db_err.html">DB-&gt;err</a>.
+This method works like the ANSI C printf interface.  The second argument
+is the error return from a Berkeley DB function, and the rest of the arguments
+are a printf-style format string and argument list.  The error message
+associated with the error return will be appended to a message constructed
+from the format string and other arguments.  In the above code, if the
+<a href="../../api_c/db_open.html">DB-&gt;open</a> call were to fail, the message it would display would be
+something like
+<p><blockquote><pre>access.db: Operation not permitted</pre></blockquote>

+<h1 align=center>Adding elements to a database</h1>
+<p>The simplest way to add elements to a database is the <a href="../../api_c/db_put.html">DB-&gt;put</a>
+interface.
+<p>The <a href="../../api_c/db_put.html">DB-&gt;put</a> interface takes five arguments:
+<p><dl compact>
+<p><dt>db<dd>The database handle returned by <a href="../../api_c/db_create.html">db_create</a>.
+<p><dt>txnid<dd>A transaction handle.  In our simple case, we aren't expecting to
+recover the database after application or system crash, so we aren't
+using transactions, and will leave this argument NULL.
+<p><dt>key<dd>The key item for the key/data pair that we want to add to the database.
+<p><dt>data<dd>The data item for the key/data pair that we want to add to the database.
+<p><dt>flags<dd>Optional flags modifying the underlying behavior of the <a href="../../api_c/db_put.html">DB-&gt;put</a>
+interface.
+</dl>
+<p>Here's what the code to call <a href="../../api_c/db_put.html">DB-&gt;put</a> looks like:
+<p><blockquote><pre>#include &lt;sys/types.h&gt;
+#include &lt;stdio.h&gt;
+#include &lt;db.h&gt;
+<p>
+#define	DATABASE "access.db"
+<p>
+int
+main()
+{
+	DB *dbp;
+	<b>DBT key, data;</b>
+	int ret;
+<p>
+	if ((ret = db_create(&dbp, NULL, 0)) != 0) {
+		fprintf(stderr, "db_create: %s\n", db_strerror(ret));
+		exit (1);
+	}
+	if ((ret = dbp-&gt;open(
+	    dbp, DATABASE, NULL, DB_BTREE, DB_CREATE, 0664)) != 0) {
+		dbp-&gt;err(dbp, ret, "%s", DATABASE);
+		goto err;
+	}
+<p><b>	memset(&key, 0, sizeof(key));
+	memset(&data, 0, sizeof(data));
+	key.data = "fruit";
+	key.size = sizeof("fruit");
+	data.data = "apple";
+	data.size = sizeof("apple");
+<p>
+	if ((ret = dbp-&gt;put(dbp, NULL, &key, &data, 0)) == 0)
+		printf("db: %s: key stored.\n", (char *)key.data);
+	else {
+		dbp-&gt;err(dbp, ret, "DB-&gt;put");
+		goto err;
+	}
+</b></pre></blockquote>
+<p>The first thing to notice about this new code is that we clear the
+<a href="../../api_c/dbt.html">DBT</a> structures that we're about to pass as arguments to Berkeley DB
+functions.  This is very important, and being careful to do so will
+result in fewer errors in your programs.  All Berkeley DB structures
+instantiated in the application and handed to Berkeley DB should be cleared
+before use, without exception.  This is necessary so that future
+versions of Berkeley DB may add additional fields to the structures.  If
+applications clear the structures before use, it will be possible for
+Berkeley DB to change those structures without requiring that the applications
+be rewritten to be aware of the changes.
+<p>Notice also that we're storing the trailing nul byte found in the C
+strings <b>"fruit"</b> and <b>"apple"</b> in both the key and data
+items, that is, the trailing nul byte is part of the stored key, and
+therefore has to be specified in order to access the data item.  There is
+no requirement to store the trailing nul byte, it simply makes it easier
+for us to display strings that we've stored in programming languages that
+use nul bytes to terminate strings.
+<p>In many applications, it is important not to overwrite existing
+data.  For example, we might not want to store the key/data pair
+<b>fruit/apple</b> if it already existed, e.g., if someone had
+previously stored the key/data pair <b>fruit/cherry</b> into the
+database.
+<p>This is easily accomplished by adding the <a href="../../api_c/db_put.html#DB_NOOVERWRITE">DB_NOOVERWRITE</a> flag to
+the <a href="../../api_c/db_put.html">DB-&gt;put</a> call:
+<p><blockquote><pre><b>if ((ret =
+	dbp-&gt;put(dbp, NULL, &key, &data, DB_NOOVERWRITE)) == 0)
+		printf("db: %s: key stored.\n", (char *)key.data);
+else {
+	dbp-&gt;err(dbp, ret, "DB-&gt;put");
+	goto err;
+}</b></pre></blockquote>
+<p>This flag causes the underlying database functions to not overwrite any
+previously existing key/data pair.  (Note that the value of the previously
+existing data doesn't matter in this case.  The only question is if a
+key/data pair already exists where the key matches the key that we are
+trying to store.)
+<p>Specifying <a href="../../api_c/db_put.html#DB_NOOVERWRITE">DB_NOOVERWRITE</a> opens up the possibility of a new
+Berkeley DB return value from the <a href="../../api_c/db_put.html">DB-&gt;put</a> function, <a href="../../api_c/dbc_put.html#DB_KEYEXIST">DB_KEYEXIST</a>,
+which means we were unable to add the key/data pair to the database
+because the key already existed in the database.  While the above sample
+code simply displays a message in this case:
+<p><blockquote><pre>DB-&gt;put: DB_KEYEXIST: Key/data pair already exists</pre></blockquote>
+<p>The following code shows an explicit check for this possibility:
+<p><blockquote><pre><b>switch (ret =
+	dbp-&gt;put(dbp, NULL, &key, &data, DB_NOOVERWRITE)) {
+case 0:
+	printf("db: %s: key stored.\n", (char *)key.data);
+	break;
+case DB_KEYEXIST:
+	printf("db: %s: key previously stored.\n",
+	(char *)key.data);
+	break;
+default:
+	dbp-&gt;err(dbp, ret, "DB-&gt;put");
+	goto err;
+}</b></pre></blockquote>

+<h1 align=center>Tcl error handling</h1>
+<p>The Tcl interfaces to Berkeley DB generally return TCL_OK on success and throw
+a Tcl error on failure, using the appropriate Tcl interfaces to provide
+the user with an informative error message.  There are some "expected"
+failures, however, for which no Tcl error will be thrown and for which
+Tcl commands will return TCL_OK.  These failures include when a
+searched-for key is not found, a requested key/data pair was previously
+deleted, or a key/data pair cannot be written because the key already
+exists.
+<p>These failures can be detected by searching the Berkeley DB error message that
+is returned.  For example, to detect that an attempt to put a record into
+the database failed because the key already existed:
+<p><blockquote><pre>% berkdb open -create -btree a.db
+db0
+% db0 put dog cat
+0
+% set ret [db0 put -nooverwrite dog newcat]
+DB_KEYEXIST: Key/data pair already exists
+% if { [string first DB_KEYEXIST $ret] != -1 } {
+	puts "This was an error; the key existed"
+}
+This was an error; the key existed
+% db0 close
+0
+% exit</pre></blockquote>
+<p>To simplify parsing, it is recommended that the initial Berkeley DB error name
+be checked, e.g., DB_KEYEXIST in the above example.  These values will
+not change in future releases of Berkeley DB to ensure that Tcl scripts are not
+broken by upgrading to new releases of Berkeley DB.  There are currently only
+three such "expected" error returns.  They are:
+<p><blockquote><pre>DB_NOTFOUND: No matching key/data pair found
+DB_KEYEMPTY: Non-existent key/data pair
+DB_KEYEXIST: Key/data pair already exists</pre></blockquote>
+<p>Finally, in some cases, when a Berkeley DB error occurs Berkeley DB will output
+additional error information.  By default, all Berkeley DB error messages will
+be prefixed with the created command in whose context the error occurred
+(e.g., "env0", "db2", etc.).  There are several ways to capture and
+access this information.
+<p>First, if Berkeley DB invokes the error callback function, the additional
+information will be placed in the error result returned from the
+command and in the errorInfo backtrace variable in Tcl.
+<p>Also the two calls to open an environment and
+open a database take an option, <b>-errfile filename</b>, which sets an
+output file to which these additional error messages should be written.
+<p>Additionally the two calls to open an environment and
+open a database take an option, <b>-errpfx string</b>, which sets the
+error prefix to the given string.  This option may be useful
+in circumstances where a more descriptive prefix is desired or
+where a constant prefix indicating an error is desired.

+<h1 align=center>Frequently Asked Questions</h1>
+<p><ol>
+<p><li><b>I have several versions of Tcl installed. How do I configure
+Berkeley DB to use a particular version?</b>
+<p>To compile the Tcl interface with a particular version of Tcl, use the
+--with-tcl option to specify the Tcl installation directory that contains
+the tclConfig.sh file.
+<p>See <a href="../../ref/build_unix/flags.html">Changing compile or load options</a>
+for more information.
+<hr size=1 noshade>
+<p><li><b>Berkeley DB was configured using --enable-tcl or --with-tcl and fails
+to build.</b>
+<p>The Berkeley DB Tcl interface requires Tcl version 8.1 or greater.  You can
+download a copy of Tcl from the
+<a href="http://www.ajubasolutions.com/home.html">Ajuba Solutions</a>
+corporate web site.
+<hr size=1 noshade>
+<p><li><b>Berkeley DB was configured using --enable-tcl or --with-tcl and fails
+to build.</b>
+<p>If the Tcl installation was moved after it was configured and installed,
+try re-configuring and re-installing Tcl.
+<p>Also, some systems do not search for shared libraries by default, or do
+not search for shared libraries named the way the Tcl installation names
+them, or are searching for a different kind of library than those in
+your Tcl installation.  For example, Linux systems often require linking
+"libtcl.a" to "libtcl#.#.a", while AIX systems often require adding the
+"-brtl" flag to the linker.  A simpler solution that almost always works
+on all systems is to create a link from "libtcl.#.#.a" or "libtcl.so"
+(or whatever you happen to have) to "libtcl.a" and reconfigure.
+<hr size=1 noshade>
+<p><li><b>Loading the Berkeley DB library into Tcl on AIX causes a core dump.</b>
+<p>In some versions of Tcl, the "tclConfig.sh" autoconfiguration script
+created by the Tcl installation does not work properly under AIX.  To
+build a working Berkeley DB Tcl API when this happens, use the "--enable-tcl"
+flag to configure Berkeley DB (rather than "--with-tcl").  In addition, you
+will have to specify any necessary include and library paths and linker
+flags needed to build with Tcl by setting the CPPFLAGS, LIBS and LDFLAGS
+environment variables before running configure.

+<h1 align=center>Loading Berkeley DB with Tcl</h1>
+<p>Berkeley DB includes a dynamically loadable Tcl API. The Tcl API requires that
+Tcl/Tk 8.1 or later already be installed on your system.  We recommend
+that you install later releases of Tcl/Tk than 8.1, if possible,
+especially on Windows platforms, as we found that we had to make local
+fixes to the 8.1 release in a few cases.  You can download a copy of
+Tcl from the <a href="http://www.ajubasolutions.com/home.html">Ajuba
+Solutions</a> corporate web site.
+<p>This document assumes that you have already configured Berkeley DB for Tcl
+support and you have built and installed everything where you want it
+to be.  If you have not done so, see
+<a href="../../ref/build_unix/conf.html">Configuring Berkeley DB</a> or
+<a href="../../ref/build_win/intro.html">Building for Win32</a> for more
+information.
+<h3>Installing as a Tcl Package</h3>
+<p>Once enabled, the Berkeley DB shared library for Tcl is automatically installed
+as part of the standard installation process.  However, if you wish to be
+able to dynamically load it as a Tcl package into your script there are
+several steps that must be performed:
+<p><ol>
+<p><li>Run the Tcl shell in the install directory
+<li>Append this directory to your auto_path variable
+<li>Run the pkg_mkIndex proc giving the name of the Berkeley DB Tcl library
+</ol>
+<p>For example:
+<p><blockquote><pre># tclsh8.1
+% lappend auto_path /usr/local/BerkeleyDB/lib
+% pkg_mkIndex /usr/local/BerkeleyDB/lib libdb_tcl-3.2.so libdb-3.2.so</pre></blockquote>
+<p>Note that your Tcl and Berkeley DB version numbers may differ from the example,
+and so your tclsh and and library names may be different.
+<h3>Loading Berkeley DB with Tcl</h3>
+<p>The Berkeley DB package may be loaded into the user's interactive Tcl script
+(or wish session) via the "load" command. For example:
+<p><blockquote><pre>load /usr/local/BerkeleyDB/lib/libdb_tcl-3.2.so</pre></blockquote>
+<p>Note that your Berkeley DB version numbers may differ from the example, and so
+the library name may be different.
+<p>If you installed your library to run as a Tcl package, Tcl application
+scripts should use the "package" command to indicate to the Tcl
+interpreter that it needs the Berkeley DB package and where to find it. For
+example:
+<p><blockquote><pre>lappend auto_path "/usr/local/BerkeleyDB/lib"
+package require Db_tcl</pre></blockquote>
+<p>No matter which way the library gets loaded, it creates a command named
+<b>berkdb</b>.  All of the Berkeley DB functionality is accessed via this
+command and additional commands it creates on behalf of the application.
+A simple test to determine if everything is loaded and ready is to ask
+for the version:
+<p><blockquote><pre>berkdb version -string</pre></blockquote>
+<p>This should return you the Berkeley DB version in a string format.

+<h1 align=center>Tcl API programming notes</h1>
+<p>The Tcl API closely parallels the Berkeley DB programmatic interfaces.  If you
+are already familiar with one of those interfaces there will not be many
+surprises in the Tcl API.
+<p>Several pieces of Berkeley DB functionality are not available in the Tcl API.
+Any of the functions that require a user-provided function are not
+supported via the Tcl API. For example, there is no equivalent to the
+<a href="../../api_c/db_set_dup_compare.html">DB-&gt;set_dup_compare</a> or the <a href="../../api_c/env_set_errcall.html">DBENV-&gt;set_errcall</a>
+methods.
+<p>The Berkeley DB Tcl API always turns on the DB_THREAD flag for environments and
+databases making no assumptions about the existence or lack thereof of
+threads support in current or future releases of Tcl.

+<h1 align=center>Using Berkeley DB with Tcl</h1>
+<p>All commands in the Berkeley DB Tcl interface are of the form:
+<p><blockquote><pre>command_handle operation options</pre></blockquote>
+<p>The <i>command handle</i> is <b>berkdb</b> or one of the additional
+commands that may be created. The <i>operation</i> is what you want
+to do to that handle and the <i>options</i> apply to the operation.
+Commands that get created on behalf of the application have their own sets
+of operations.  Generally any calls in DB that result in new object
+handles will translate into a new command handle in Tcl. Then the user
+can access the operations of the handle via the new Tcl command handle.
+<p>Newly created commands are named with an abbreviated form of their objects
+followed by a number. Some created commands are subcommands of other
+created commands and will be the first command, followed by a period, '.'
+followed by the new subcommand. For example, suppose you have a database
+already existing called my_data.db. The following example shows the
+commands created when you open the database, and when you open a cursor:
+<p><blockquote><pre># First open the database and get a database command handle
+% berkdb open my_data.db
+db0
+#Get some data from that database
+% db0 get my_key
+{{my_key my_data0}{my_key my_data1}}
+#Open a cursor in this database, get a new cursor handle
+% db0 cursor
+db0.c0
+#Get the first data from the cursor
+% db0.c0 get -first
+{{first_key first_data}}</pre></blockquote>
+<p>All commands in the library support a special option <b>-?</b> that will
+list the correct operations for a command or the correct options.
+<p>A list of commands and operations can be found in the
+<a href="../../api_tcl/tcl_index.html">Tcl Interface</a> documentation.

+<h1 align=center>Running the test suite</h1>
+<p>Once you have started tclsh and have loaded the test.tcl source file (see
+<a href="../../ref/build_unix/test.html">Running the test suite under UNIX</a>
+and <a href="../../ref/build_win/test.html">Running the test suite under
+Windows</a> for more information), you are ready to run the test suite.  At
+the tclsh prompt, to run the entire test suite, enter:
+<p><blockquote><pre>% run_all</pre></blockquote>
+<p>Running all the tests can take from several hours to a few days to
+complete, depending on your hardware.  For this reason, the output from
+this command is re-directed to a file in the current directory named
+<b>ALL.OUT</b>.  Periodically, a line will be written to the standard
+output indicating what test is being run.  When the suite has finished,
+a single message indicating that the test suite completed successfully or
+that it failed will be written.  If the run failed, you should review the
+file ALL.OUT to determine which tests failed.  Any errors will appear in
+that file as output lines beginning with the string: FAIL.
+<p>It is also possible to run specific tests or tests for a particular
+subsystem:
+<p><blockquote><pre>% r archive
+% r btree
+% r env
+% r frecno
+% r hash
+% r join
+% r join
+% r lock
+% r log
+% r mpool
+% r mutex
+% r queue
+% r rbtree
+% r recno
+% r rrecno
+% r subdb
+% r txn</pre></blockquote>
+<p>Or to run a single, individual test:
+<p><blockquote><pre>% test001 btree</pre></blockquote>
+<p>It is also possible to modify the test run based on arguments on the
+command line.  For example, the command:
+<p><blockquote><pre>% test001 btree 10</pre></blockquote>
+<p>will run a greatly abbreviated form of test001, doing 10 operations
+instead of 10,000.
+<p>In all cases, when not running the entire test suite as described above,
+a successful test run will return you to the tclsh prompt (%).  On
+failure, a message is displayed indicating what failed.
+<p>Tests are run, by default, in the directory <b>TESTDIR</b>.  However,
+the test files are often very large.  To use a different directory for
+the test directory, edit the file include.tcl in your build directory,
+and change the line:
+<p><blockquote><pre>set testdir ./TESTDIR</pre></blockquote>
+<p>to a more appropriate value for your system, e.g.:
+<p><blockquote><pre>set testdir /var/tmp/db.test</pre></blockquote>
+<p>Alternatively, you can create a symbolic link named TESTDIR in your build
+directory to an appropriate location for running the tests.  Regardless
+of where you run the tests, the TESTDIR directory should be on a local
+filesystem, using a remote filesystem (e.g., NFS) will almost certainly
+cause spurious test failures.

+<h1 align=center>Environment infrastructure</h1>
+<p>When building transactional applications, it is usually necessary to
+build an administrative infrastructure around the database environment.
+There are five components to this infrastructure, and each is
+supported by the Berkeley DB package in two different ways: a standalone
+utility and one or more library interfaces.
+<ul type=disc>
+<li>Deadlock detection: <a href="../../utility/db_deadlock.html">db_deadlock</a>,

+<li>Recovery procedures: <a href="../../utility/db_recover.html">db_recover</a>, <a href="../../api_c/env_open.html">DBENV-&gt;open</a>
+</ul>
+<p>When writing multi-threaded server applications and/or applications
+intended for download from the web, it is usually simpler to create
+local threads that are responsible for administration of the database
+environment as scheduling is often simpler in a single-process model,
+and only a single binary need be installed and run.  However, the
+supplied utilities can be generally useful tools even when the
+application is responsible for doing its own administration, as
+applications rarely offer external interfaces to database
+administration.  The utilities are required when programming to a Berkeley DB
+scripting interface, as the scripting APIs do not always offer
+interfaces to the administrative functionality.

+<p>
+<h1 align=center>Application structure</h1>
+<p>When building transactionally protected applications, there are some
+special issues that must be considered.  The most important one is that,
+if any thread of control exits for any reason while holding Berkeley DB
+resources, recovery must be performed to:
+<ul type=disc>
+<li>recover the Berkeley DB resources,
+<li>release any locks or mutexes that may have been held to avoid starvation
+as the remaining threads of control convoy behind the failed thread's
+locks, and
+<li>clean up any partially completed operations that may have left a
+database in an inconsistent or corrupted state.
+</ul>
+<p>Complicating this problem is the fact that the Berkeley DB library itself
+cannot determine if recovery is required, the application itself
+<b>must</b> make that decision.  A further complication is that
+recovery must be single-threaded, that is, one thread of control or
+process must perform recovery before any other thread of control or
+processes attempts to create or join the Berkeley DB environment.
+<p>There are two approaches to handling this problem:
+<p><dl compact>
+<p><dt>The hard way:<dd>An application can track its own state carefully enough that it knows
+when recovery needs to be performed.  Specifically, the rule to use is
+that recovery must be performed before using a Berkeley DB environment any
+time the threads of control previously using the Berkeley DB environment did
+not shut the environment down cleanly before exiting the environment
+for any reason (including application or system failure).
+<p>Requirements for shutting down the environment cleanly differ depending
+on the type of environment created.  If the environment is public and
+persistent (i.e., the <a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag was not specified to the
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> function), recovery must be performed if any transaction was
+not committed or aborted, or <a href="../../api_c/env_close.html">DBENV-&gt;close</a> function was not called for
+any open DB_ENV handle.
+<p>If the environment is private and temporary (i.e., the <a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a>
+flag was specified to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function), recovery must be performed
+if any transaction was not committed or aborted, or <a href="../../api_c/env_close.html">DBENV-&gt;close</a> function
+was not called for any open DB_ENV handle.  In addition, at least
+one transaction checkpoint must be performed after all existing
+transactions have been committed or aborted.
+<p><dt>The easy way:<dd>It greatly simplifies matters that recovery may be performed regardless
+of whether recovery strictly needs to be performed, that is, it is not
+an error to run recovery on a database where no recovery is necessary.
+Because of this fact, it is almost invariably simpler to ignore the
+above rules about shutting an application down cleanly, and simply run
+recovery each time a thread of control accessing a database environment
+fails for any reason, as well as before accessing any database
+environment after system reboot.
+</dl>
+<p>There are two common ways to build transactionally protected Berkeley DB
+applications.  The most common way is as a single, usually
+multi-threaded, process.  This architecture is simplest because it
+requires no monitoring of other threads of control.  When the
+application starts, it opens and potentially creates the environment,
+runs recovery (whether it was needed or not), and then opens its
+databases.  From then on, the application can create new threads of
+control as it chooses.  All threads of control share the open Berkeley DB
+DB_ENV and DB handles.  In this model, databases are
+rarely opened or closed when more than a single thread of control is
+running, that is, they are opened when only a single thread is running,
+and closed after all threads but one have exited.  The last thread of
+control to exit closes the databases and the environment.
+<p>An alternative way to build Berkeley DB applications is as a set of
+cooperating processes, which may or may not be multi-threaded.  This
+architecture is more complicated.
+<p>First, this architecture requires that the order in which threads of
+control are created and subsequently access the Berkeley DB environment be
+controlled, because recovery must be single-threaded.  The first thread
+of control to access the environment must run recovery, and no other
+thread should attempt to access the environment until recovery is
+complete.  (Note that this ordering requirement does not apply to
+environment creation without recovery.  If multiple threads attempt to
+create a Berkeley DB environment, only one will perform the creation and the
+others will join the already existing environment.)
+<p>Second, this architecture requires that threads of control be monitored.
+If any thread of control that owns Berkeley DB resources exits, without first
+cleanly discarding those resources, recovery is usually necessary.
+Before running recovery, all threads using the Berkeley DB environment must
+relinquish all of their Berkeley DB resources (it does not matter if they do
+so gracefully or because they are forced to exit).  Then recovery can
+be run and the threads of control continued or re-started.
+<p>We have found that the safest way to structure groups of cooperating
+processes is to first create a single process (often a shell script)
+that opens/creates the Berkeley DB environment and runs recovery, and which
+then creates the processes or threads that will actually perform work.
+The initial thread has no further responsibilities other than to monitor
+the threads of control it has created, to ensure that none of them
+unexpectedly exits.  If one exits, the initial process then forces all
+of the threads of control using the Berkeley DB environment to exit, runs
+recovery, and restarts the working threads of control.
+<p>If it is not practical to have a single parent for the processes sharing
+a Berkeley DB environment, each process sharing the environment should log
+their connection to and exit from the environment in some fashion that
+permits a monitoring process to detect if a thread of control may have
+potentially acquired Berkeley DB resources and never released them.
+<p>Obviously, it is important that the monitoring process in either case
+be as simple and well-tested as possible as there is no recourse should
+it fail.

+<h1 align=center>Database and log file archival</h1>
+        <a name="3"><!--meow--></a>    
+<p>The third component of the administrative infrastructure, archival for
+catastrophic recovery, concerns the recoverability of the database in
+the face of catastrophic failure.  Recovery after catastrophic failure
+is intended to minimize data loss when physical hardware has been
+destroyed, for example, loss of a disk that contains databases or log
+files.  While the application may still experience data loss in this
+case, it is possible to minimize it.
+<p>First, you may want to periodically create snapshots (i.e., backups) of
+your databases to make it possible to recover from catastrophic failure.
+These snapshots are either a standard backup which creates a consistent
+picture of the databases as of a single instant in time, or an on-line
+backup (also known as a <i>hot</i> backup), which creates a
+consistent picture of the databases as of an unspecified instant during
+the period of time when the snapshot was made.  The advantage of a hot
+backup is that applications may continue to read and write the databases
+while the snapshot is being taken.  The disadvantage of a hot backup is
+that more information must be archived, and recovery based on a hot
+backup is to an unspecified time between the start of the backup and
+when the backup is completed.
+<p>Second, after taking a snapshot, you should periodically archive the
+log files being created in the environment.  It is often helpful to
+think of database archival in terms of full and incremental filesystem
+backups.  A snapshot is a full backup, while the periodic archival of
+the current log files is an incremental.  For example, it might be
+reasonable to take a full snapshot of a database environment weekly or
+monthly, and then archive additional log files daily.  Using both the
+snapshot and the log files, a catastrophic crash at any time can be
+recovered to the time of the most recent log archival, a time long after
+the original snapshot.
+<p>To create a standard backup of your database that can be used to recover
+from catastrophic failure, take the following steps:
+<p><ol>
+<p><li>Commit or abort all on-going transactions.
+<p><li>Force an environment checkpoint (see <a href="../../utility/db_checkpoint.html">db_checkpoint</a> for more
+information).
+<p><li>Stop writing your databases until the backup has completed.  Read-only
+operations are permitted, but no write operations and no filesystem
+operations may be performed, e.g., the <a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> and
+<a href="../../api_c/db_open.html">DB-&gt;open</a> functions may not be called).
+<p><li>Run <a href="../../utility/db_archive.html">db_archive</a> <b>-s</b> to identify all of the database data
+files, and copy them to a backup device, such as CDROM, alternate disk,
+or tape.  Obviously, the reliability of your archive media will affect
+the safety of your data.
+<p>If the database files are stored in a separate directory from the other
+Berkeley DB files, it may be simpler to archive the directory itself instead
+of the individual files (see <a href="../../api_c/env_set_data_dir.html">DBENV-&gt;set_data_dir</a> for additional
+information).  If you are performing a hot backup, the utility you use
+to copy the files must read database pages atomically (as described by
+<a href="../../ref/transapp/reclimit.html">Berkeley DB recoverability</a>).
+<p><b>Note: if any of the database files did not have an open DB
+handle during the lifetime of the current log files, <a href="../../utility/db_archive.html">db_archive</a>
+will not list them in its output!</b> For this reason, it may be simpler
+to use a separate database file directory, and archive the entire
+directory instead of only the files listed by <a href="../../utility/db_archive.html">db_archive</a>.
+</ol>
+<p>To create a <i>hot</i> backup of your database that can be used to
+recover from catastrophic failure, take the following steps:
+<p><ol>
+<p><li>Archive your databases as described in Step #4 above.  You
+do not have to halt on-going transactions or force a checkpoint.
+<p><li>When performing a hot backup, you must additionally archive the active
+log files.  Note that the order of these two operations is required,
+and the database files must be archived before the log files.  This
+means that if the database files and log files are in the same
+directory, you cannot simply archive the directory, you must make sure
+that the correct order of archival is maintained.
+<p>To archive your log files, run the <a href="../../utility/db_archive.html">db_archive</a> utility, using
+the <b>-l</b> option, to identify all of the database log files, and
+copy them to your backup media.  If the database log files are stored
+in a separate directory from the other database files, it may be simpler
+to archive the directory itself instead of the individual files (see
+the <a href="../../api_c/env_set_lg_dir.html">DBENV-&gt;set_lg_dir</a> function for more information).
+</ol>
+<p>Once these steps are completed, your database can be recovered from
+catastrophic failure (see <a href="recovery.html">Recovery procedures</a> for
+more information).
+<p>To update your snapshot so that recovery from catastrophic failure is
+possible up to a new point in time, repeat step #2 under the hot backup
+instructions, copying all existing log files to a backup device.  This
+is applicable to both standard and hot backups, that is, you can update
+snapshots made in either way.  Each time both the database and log files
+are copied to backup media, you may discard all previous database
+snapshots and saved log files.  Archiving additional log files does not
+allow you to discard either previous database snapshots or log files.
+<p>The time to restore from catastrophic failure is a function of the
+number of log records that have been written since the snapshot was
+originally created.  Perhaps more importantly, the more separate pieces
+of backup media you use, the more likely that you will have a problem
+reading from one of them.  For these reasons, it is often best to make
+snapshots on a regular basis.
+<p><b>For archival safety, ensure that you have multiple copies of your
+database backups, verify that your archival media is error-free and
+readable, and that copies of your backups are stored off-site!</b>
+<p>The functionality provided by the <a href="../../utility/db_archive.html">db_archive</a> utility is also
+available directly from the Berkeley DB library.  The following code fragment
+prints out a list of log and database files that need to be archived.
+<p><blockquote><pre>void
+log_archlist(DB_ENV *dbenv)
+{
+	int ret;
+	char **begin, **list;

+<h1 align=center>Checkpoints</h1>
+<p>The second component of the infrastructure is performing checkpoints of
+the log files.  As transactions commit, change records are written into
+the log files, but the actual changes to the database are not
+necessarily written to disk.  When a checkpoint is performed, the
+changes to the database that are part of committed transactions are
+written into the backing database file.
+<p>Performing checkpoints is necessary for two reasons.  First, you can
+only remove the Berkeley DB log files from your system after a checkpoint.
+Second, the frequency of your checkpoints is inversely proportional to
+the amount of time it takes to run database recovery after a system or
+application failure.
+<p>Once the database pages are written, log files can be archived and removed
+from the system because they will never be needed for anything other than
+catastrophic failure.  In addition, recovery after system or application
+failure only has to redo or undo changes since the last checkpoint, since
+changes before the checkpoint have all been flushed to the filesystem.
+<p>Berkeley DB provides a separate utility, <a href="../../utility/db_checkpoint.html">db_checkpoint</a>, which can be
+used to perform checkpoints.  Alternatively, applications can write
+their own checkpoint utility using the underlying <a href="../../api_c/txn_checkpoint.html">txn_checkpoint</a>
+function.  The following code fragment checkpoints the database
+environment every 60 seconds:
+<p><blockquote><pre>int

+<h1 align=center>Transactional cursors</h1>
+<p>Berkeley DB cursors may be used inside a transaction, exactly like any other
+DB method.  The enclosing transaction ID must be specified when
+the cursor is created, but it does not then need to be further specified
+on operations performed using the cursor.  One important point to
+remember is that a cursor <b>must be closed</b> before the enclosing
+transaction is committed or aborted.
+<p>The following code fragment uses a cursor to store a new key in the cats
+database with four associated data items.  The key is a name.  The data
+items are a company name, an address, and a list of the breeds of cat
+owned.  Each of the data entries is stored as a duplicate data item.
+In this example, transactions are necessary to ensure that either all or none
+of the data items appear in case of system or application failure.

+<h1 align=center>Deadlock detection</h1>
+<p>The first component of the infrastructure, deadlock detection, is not
+so much a requirement specific to transaction protected applications,
+but rather is necessary for almost all applications where more than a
+single thread of control will be accessing the database at one time.
+While Berkeley DB automatically handles database locking, it is normally
+possible for deadlock to occur.  It is not required by all transactional
+applications, but exceptions are rare.
+<p>When the deadlock occurs, two (or more) threads of control each request
+additional locks which can never be granted because one of the threads
+of control waiting holds the requested resource.
+<p>For example, consider two processes A and B.  Let's say that A obtains
+an exclusive lock on item X, and B obtains an exclusive lock on item Y.
+Then, A requests a lock on Y and B requests a lock on X.  A will wait
+until resource Y becomes available and B will wait until resource X
+becomes available.  Unfortunately, since both A and B are waiting,
+neither will release the locks they hold and neither will ever obtain
+the resource on which it is waiting.  In order to detect that deadlock
+has happened, a separate process or thread must review the locks
+currently held in the database.  If deadlock has occurred, a victim must
+be selected, and that victim will then return the error
+<a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a> from whatever Berkeley DB call it was making.
+<p>Berkeley DB provides a separate UNIX-style utility which can be used to
+perform this deadlock detection, named <a href="../../utility/db_deadlock.html">db_deadlock</a>.
+Alternatively, applications can create their own deadlock utility or
+thread using the underlying <a href="../../api_c/lock_detect.html">lock_detect</a> function, or specify
+that Berkeley DB run the deadlock detector internally whenever there is a
+conflict over a lock (see <a href="../../api_c/env_set_lk_detect.html">DBENV-&gt;set_lk_detect</a> for more
+information).  The following code fragment does the latter:
+<p><blockquote><pre>void
+env_open(DB_ENV **dbenvp)
+{
+	DB_ENV *dbenv;
+	int ret;
+<p>
+	/* Create the environment handle. */
+	if ((ret = db_env_create(&dbenv, 0)) != 0) {
+		fprintf(stderr,
+		    "txnapp: db_env_create: %s\n", db_strerror(ret));
+		exit (1);
+	}
+<p>
+	/* Set up error handling. */
+	dbenv-&gt;set_errpfx(dbenv, "txnapp");
+<p>
+<b>	/* Do deadlock detection internally. */
+	if ((ret = dbenv-&gt;set_lk_detect(dbenv, DB_LOCK_DEFAULT)) != 0) {
+		dbenv-&gt;err(dbenv, ret, "set_lk_detect: DB_LOCK_DEFAULT");
+		exit (1);
+	}</b>
+<p>
+	/*
+	 * Open a transactional environment:
+	 *	create if it doesn't exist
+	 *	free-threaded handle
+	 *	run recovery
+	 *	read/write owner only
+	 */
+	if ((ret = dbenv-&gt;open(dbenv, ENV_DIRECTORY,
+	    DB_CREATE | DB_INIT_LOCK | DB_INIT_LOG |
+	    DB_INIT_MPOOL | DB_INIT_TXN | DB_RECOVER | DB_THREAD,
+	    S_IRUSR | S_IWUSR)) != 0) {
+		dbenv-&gt;err(dbenv, ret, "dbenv-&gt;open: %s", ENV_DIRECTORY);
+		exit (1);
+	}
+<p>
+	*dbenvp = dbenv;
+}</pre></blockquote>
+<p>Deciding how often to run the deadlock detector and which of the
+deadlocked transactions will be forced to abort when the deadlock is
+detected is a common tuning parameter for Berkeley DB applications.

+<h1 align=center>Opening the environment</h1>
+<p>Creating transaction-protected applications using the Berkeley DB library is
+quite easy.  Applications first use <a href="../../api_c/env_open.html">DBENV-&gt;open</a> to initialize
+the database environment.  Transaction-protected applications normally
+require all four Berkeley DB subsystems, so the <a href="../../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a>,
+<a href="../../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a>, <a href="../../api_c/env_open.html#DB_INIT_LOG">DB_INIT_LOG</a> and <a href="../../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a> flags
+should be specified.
+<p>Once the application has called <a href="../../api_c/env_open.html">DBENV-&gt;open</a>, it opens its
+databases within the environment.  Once the databases are opened, the
+application makes changes to the databases inside of transactions.  Each
+set of changes that entail a unit of work should be surrounded by the
+appropriate <a href="../../api_c/txn_begin.html">txn_begin</a>, <a href="../../api_c/txn_commit.html">txn_commit</a> and <a href="../../api_c/txn_abort.html">txn_abort</a>
+calls.  The Berkeley DB access methods will make the appropriate calls into
+the lock, log and memory pool subsystems in order to guarantee
+transaction semantics.  When the application is ready to exit, all
+outstanding transactions should have been committed or aborted.
+<p>Databases accessed by a transaction must not be closed during the
+transaction.  Once all outstanding transactions are finished, all open
+Berkeley DB files should be closed.  When the Berkeley DB database files have been
+closed, the environment should be closed by calling <a href="../../api_c/env_close.html">DBENV-&gt;close</a>.
+<p>The following code fragment creates the database environment directory,
+then opens the environment, running recovery.  Our DB_ENV
+database environment handle is declared to be free-threaded using the
+<a href="../../api_c/env_open.html#DB_THREAD">DB_THREAD</a> flag, and so may be used by any number of threads that
+we may subsequently create.

+<h1 align=center>Recovery and filesystem operations</h1>
+<p>When running in a transaction-protected environment, database creation
+and deletion are logged as stand-alone transactions internal to Berkeley DB.
+That is, for each such operation a new transaction is begun and aborted
+or committed internally, so that they will be recovered during recovery.
+<p>The Berkeley DB API supports removing and renaming files.  Renaming files is
+supported by the <a href="../../api_c/db_rename.html">DB-&gt;rename</a> method, and removing files by the
+<a href="../../api_c/db_remove.html">DB-&gt;remove</a> method.  Berkeley DB does not permit specifying the
+<a href="../../api_c/db_open.html#DB_TRUNCATE">DB_TRUNCATE</a> flag when opening a file in a transaction protected
+environment.  This is an implicit file deletion, but one that does not
+always require the same operating system file permissions as does deleting
+and creating a file.
+<p>If you have changed the name of a file or deleted it outside of the Berkeley DB
+library (e.g., you explicitly removed a file using your normal operating
+system utilities), then it is possible that recovery will not be able to
+find a database referenced in the log.  In this case, <a href="../../utility/db_recover.html">db_recover</a>
+will produce a warning message saying it was unable to locate a file it
+expected to find.  This message is only a warning, as the file may have
+been subsequently deleted as part of normal database operations before
+the failure occurred, and so is not necessarily a problem.
+<p>Generally, any filesystem operations that are performed outside the Berkeley DB
+interface should be performed at the same time as making a snapshot of
+the database.  To perform filesystem operations correctly:
+<p><ol>
+<p><li>Cleanly shutdown database operations.
+<p>To shutdown database operations cleanly, all applications accessing the
+database environment must be shutdown and a transaction checkpoint must
+be taken.  If the applications are not implemented such that they can be
+shutdown gracefully (i.e., closing all references to the database
+environment), recovery must be performed after all applications have been
+killed to ensure that the underlying databases are consistent on disk.
+<p><li>Perform the filesystem operations, e.g., remove or rename one
+or more files.
+<p><li>Make an archival snapshot of the database.
+<p>While this step is not strictly necessary, it is strongly recommended.
+If this step is not performed, recovery from catastrophic failure will
+require that recovery first be performed up to the time of the
+filesystem operations, the filesystem operations be redone, and then
+recovery be performed from the filesystem operations forward.
+<p><li>Restart the database applications.

+<p>
+<h1 align=center>Atomicity</h1>
+<p>The third reason listed for using transactions was atomicity.  Consider
+an application suite where multiple threads of control (multiple
+processes or threads in one or more processes) are changing the values
+associated with a key in one or more databases.  Specifically, they are
+taking the current value, incrementing it, and then storing it back into
+the database.
+<p>Such an application requires atomicity.  Since we want to change a value
+in the database, we must make sure that once we read it, no other thread
+of control modifies it.  For example, assume that both thread #1 and
+thread #2 are doing similar operations in the database, where thread #1
+is incrementing records by 3, and thread #2 is incrementing records by
+5.  We want to increment the record by a total of 8.  If the operations
+interleave in the right (well, wrong) order, that is not what will
+happen:
+<p><blockquote><pre>thread #1  <b>read</b> record: the value is 2
+thread #2  <b>read</b> record: the value is 2
+thread #2  <b>write</b> record + 5 back into the database (new value 7)
+thread #1  <b>write</b> record + 3 back into the database (new value 5)</pre></blockquote>
+<p>As you can see, instead of incrementing the record by a total of 8,
+we've only incremented it by 3, because thread #1 overwrote thread #2's
+change.  By wrapping the operations in transactions, we ensure that this
+cannot happen.  In a transaction, when the first thread reads the
+record, locks are acquired that will not be released until the
+transaction finishes, guaranteeing that all other readers and writers
+will block, waiting for the first thread's transaction to complete (or
+to be aborted).
+<p>Here is an example function that does transaction-protected increments
+on database records to ensure atomicity.

+<p>Any number of operations, on any number of databases, can be included
+in a single transaction to ensure atomicity of the operations.  There
+is, however, a trade-off between the number of operations included in
+a single transaction and both throughput and the possibility of
+deadlock.  The reason for this is because transactions acquire locks
+throughout their lifetime, and do not release them until transaction
+commit or abort.  So, the more operations included in a transaction,
+the more likely that a transaction will block other operations and that
+deadlock will occur.  However, each transaction commit requires a
+synchronous disk I/O, so grouping multiple operations into a transaction
+can increase overall throughput.  (There is one exception to this.  The
+<a href="../../api_c/env_open.html#DB_TXN_NOSYNC">DB_TXN_NOSYNC</a> option causes transactions to exhibit the ACI
+(atomicity, consistency and isolation) properties, but not D
+(durability), avoiding the synchronous disk I/O on transaction commit
+and greatly increasing transaction throughput for some applications.
+<p>When applications do create complex transactions, they often avoid
+having more than one complex transaction at a time, as simple operations
+like a single <a href="../../api_c/db_put.html">DB-&gt;put</a> are unlikely to deadlock with each other
+or the complex transaction, while multiple complex transactions are
+likely to deadlock with each other as they will both acquire many locks
+over their lifetime.  Alternatively, complex transactions can be broken
+up into smaller sets of operations, and each of those sets may be
+encapsulated in a nested transaction.  Because nested transactions may
+be individually aborted and retried without causing the entire
+transaction to be aborted, this allows complex transactions to proceed
+even in the face of heavy contention, repeatedly trying the
+sub-operations until they succeed.
+<p>It is also helpful to order operations within a transaction, that is,
+access the databases and items within the databases in the same order,
+to the extent possible, in all transactions.  Accessing databases and
+items in different orders greatly increases the likelihood of operations
+being blocked and failing due to deadlocks.

+<h1 align=center>Building transaction protected applications</h1>
+<p>It is difficult to write a useful transactional tutorial and still keep
+within reasonable bounds of documentation, that is, without writing a
+book on transactional programming.  We have two goals in this section:
+to familiarize readers with the transactional interfaces of Berkeley DB and
+to provide code building blocks that will be useful in creating
+applications.
+<p>We have not attempted to present this information using a real-world
+application.  First, transactional applications are often complex and
+time consuming to explain.  Also, one of our goals is to give you an
+understanding of the wide variety of tools Berkeley DB makes available to you,
+and no single application would use most of the interfaces included in
+the Berkeley DB library.  For these reasons, we have chosen to simply present
+the Berkeley DB data structures and programming solutions, using examples that
+differ from page to page.  All of the examples are included in a
+standalone program you can examine, modify and run, and from which you
+will be able to extract code blocks for your own applications.
+Fragments of the program will be presented throughout this chapter, and
+the complete text of the <a href="transapp.txt">example program</a>
+for IEEE/ANSI Std 1003.1 (POSIX) standard systems is included in the Berkeley DB
+distribution.

+<h1 align=center>Log file removal</h1>
+<p>The fourth component of the infrastructure, log file removal, concerns
+the ongoing disk consumption of the database log files.  Depending on
+the rate at which the application writes to the databases and the
+available disk space, the number of log files may increase quickly
+enough that disk space will be a resource problem.  For this reason,
+you will periodically want to remove log files in order to conserve disk
+space.  This procedure is distinct from database and log file archival
+for catastrophic recovery, and you cannot remove the current log files
+simply because you have created a database snapshot or copied log files
+to archival media.
+<p>Log files may be removed at any time, as long as:
+<ul type=disc>
+<li>the log file is not involved in an active transaction
+<li>at least two checkpoints have been written subsequent to the
+log file's creation, and
+<li>the log file is not the only log file in the environment.
+</ul>
+<p>Obviously, if you are preparing for catastrophic failure, you will want
+to copy the log files to archival media before you remove them.
+<p>To remove log files, take the following steps:
+<p><ol>
+<p><li>If you are concerned with catastrophic failure, first copy the log files
+to backup media as described in <a href="archival.html">Archival for
+catastrophic recovery</a>.
+<p><li>Run <a href="../../utility/db_archive.html">db_archive</a> without options to identify all of the log files
+that are no longer in use (e.g., no longer involved in an active
+transaction).
+<p><li>Remove those log files from the system.
+</ol>
+<p>The functionality provided by the <a href="../../utility/db_archive.html">db_archive</a> utility is also
+available directly from the Berkeley DB library.  The following code fragment
+removes log files that are no longer needed by the database
+environment.
+<p><blockquote><pre>int

+<p>
+<h1 align=center>Recoverability and deadlock avoidance</h1>
+<p>The first reason listed for using transactions was recoverability.  Any
+logical change to a database may require multiple changes to underlying
+data structures.  For example, modifying a record in a Btree may require
+leaf and internal pages to split, and so a single <a href="../../api_c/db_put.html">DB-&gt;put</a> method
+call can potentially require that multiple physical database pages be
+written.  If only some of those pages are written and then the system
+or application fails, the database is left inconsistent and cannot be
+used until it has been recovered, that is, until the partially completed
+changes have been undone.
+<p>Write-ahead-logging is the term that describes the underlying
+implementation that Berkeley DB uses to ensure recoverability.  What it means
+is that before any change is made to a database, information about the
+change is written to a database log.  During recovery, the log is read,
+and databases are checked to ensure that changes described in the log
+for committed transactions appear in the database.  Changes that appear
+in the database but are related to aborted or unfinished transactions
+in the log are undone from the database.
+<p>For recoverability after application or system failure, operations that
+modify the database must be protected by transactions.  More
+specifically, operations are not recoverable unless a transaction is
+begun and each operation is associated with the transaction via the
+Berkeley DB interfaces, and then the transaction successfully committed.  This
+is true even if logging is turned on in the database environment.
+<p>Here is an example function that updates a record in a database in a
+transactionally protected manner.  The function takes a key and data
+items as arguments, and then attempts to store them into the database.
+<p><blockquote><pre>int
+main(int argc, char *argv)
+{
+	extern char *optarg;
+	extern int optind;
+	DB *db_cats, *db_color, *db_fruit;
+	DB_ENV *dbenv;
+	pthread_t ptid;
+	int ch;
+<p>
+	while ((ch = getopt(argc, argv, "")) != EOF)
+		switch (ch) {
+		case '?':
+		default:
+			usage();
+		}
+	argc -= optind;
+	argv += optind;

+	env_dir_create();
+	env_open(&dbenv);
+<p>
+	/* Open database: Key is fruit class; Data is specific type. */
+	db_open(dbenv, &db_fruit, "fruit", 0);
+<p>
+	/* Open database: Key is a color; Data is an integer. */
+	db_open(dbenv, &db_color, "color", 0);
+<p>
+	/*
+	 * Open database:
+	 *	Key is a name; Data is: company name, address, cat breeds.
+	 */
+	db_open(dbenv, &db_cats, "cats", 1);
+<p>
+<b>	add_fruit(dbenv, db_fruit, "apple", "yellow delicious");</b>
+<p>
+	return (0);
+}
+<p>
+<b>void
+add_fruit(DB_ENV *dbenv, DB *db, char *fruit, char *name)
+{
+	DBT key, data;
+	DB_TXN *tid;
+	int ret;
+<p>
+	/* Initialization. */
+	memset(&key, 0, sizeof(key));
+	memset(&data, 0, sizeof(data));
+	key.data = fruit;
+	key.size = strlen(fruit);
+	data.data = name;
+	data.size = strlen(name);
+<p>
+	for (;;) {
+		/* Begin the transaction. */
+		if ((ret = txn_begin(dbenv, NULL, &tid, 0)) != 0) {
+			dbenv-&gt;err(dbenv, ret, "txn_begin");
+			exit (1);
+		}
+<p>
+		/* Store the value. */
+		switch (ret = db-&gt;put(db, tid, &key, &data, 0)) {
+		case 0:
+			/* Success: commit the change. */
+			if ((ret = txn_commit(tid, 0)) != 0) {
+				dbenv-&gt;err(dbenv, ret, "txn_commit");
+				exit (1);
+			}
+			return;
+		case DB_LOCK_DEADLOCK:
+			/* Deadlock: retry the operation. */
+			if ((ret = txn_abort(tid)) != 0) {
+				dbenv-&gt;err(dbenv, ret, "txn_abort");
+				exit (1);
+			}
+			break;
+		default:
+			/* Error: run recovery. */
+			dbenv-&gt;err(dbenv, ret, "dbc-&gt;put: %s/%s", fruit, name);
+			exit (1);
+		}
+	}
+}</b></pre></blockquote>
+<p>The second reason listed for using transactions was deadlock avoidance.
+There is a new error return in this function that you may not have seen
+before.  In transactional (not Concurrent Data Store) applications
+supporting both readers and writers or just multiple writers, Berkeley DB
+functions have an additional possible error return:
+<a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a>.  This return means that our thread of control
+deadlocked with another thread of control, and our thread was selected
+to discard all of its Berkeley DB resources in order to resolve the problem.
+In the sample code, any time the <a href="../../api_c/db_put.html">DB-&gt;put</a> function returns
+<a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a>, the transaction is aborted (by calling
+<a href="../../api_c/txn_abort.html">txn_abort</a>, which releases the transaction's Berkeley DB resources and
+undoes any partial changes to the databases), and then the transaction
+is retried from the beginning.
+<p>There is no requirement that the transaction be attempted again, but
+that is a common course of action for applications.  Applications may
+want to set an upper boundary on the number of times an operation will
+be retried, as some operations on some data sets may simply be unable
+to succeed.  For example, updating all of the pages on a large web site
+during prime business hours may simply be impossible because of the high
+access rate to the database.

+<h1 align=center>Repeatable reads</h1>
+<p>The fourth reason listed for using transactions was repeatable reads.
+Generally, most applications do not need to place reads inside a
+transaction for performance reasons.  The problem is that a
+transactionally protected cursor, reading each key/data pair in a
+database, will acquire a read lock on most of the pages in the database
+and so will gradually block all write operations on the databases until
+the transaction commits or aborts.  Note, however, if there are update
+transactions present in the application, the reading transactions must
+still use locking, and should be prepared to repeat any operation
+(possibly closing and reopening a cursor) which fails with a return
+value of <a href="../../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a>.
+<p>The exceptions to this rule are when the application is doing a
+read-modify-write operation and so requires atomicity, and when an
+application requires the ability to repeatedly access a data item
+knowing that it will not have changed.  A repeatable read simply means
+that, for the life of the transaction, every time a request is made by
+any thread of control to read a data item, it will be unchanged from
+its previous value, that is, that the value will not change until the
+transaction commits or aborts.

+<p>
+<h1 align=center>Berkeley DB recoverability</h1>
+<p>Berkeley DB recovery is based on write-ahead logging.  What this means is that,
+when a change is made to a database page, a description of the change is
+written into a log file.  This description in the log file is guaranteed
+to be written to stable storage before the database pages that were
+changed are written to stable storage.  This is the fundamental feature
+of the logging system that makes durability and rollback work.
+<p>If the application or system crashes, the log is reviewed during recovery.
+Any database changes described in the log that were part of committed
+transactions, and that were never written to the actual database itself,
+are written to the database as part of recovery.  Any database changes
+described in the log that were never committed, and that were written to
+the actual database itself, are backed-out of the the database as part of
+recovery.  This design allows the database to be written lazily, and only
+blocks from the log file have to be forced to disk as part of transaction
+commit.
+<p>There are two interfaces that are a concern when considering Berkeley DB
+recoverability:
+<p><ol>
+<p><li>The interface between Berkeley DB and the operating system/filesystem.
+<li>The interface between the operating system/filesystem and the
+underlying stable storage hardware.
+</ol>
+<p>Berkeley DB uses the operating system interfaces and its underlying filesystem
+when writing its files.  This means that Berkeley DB can fail if the underlying
+filesystem fails in some unrecoverable way.  Otherwise, the interface
+requirements here are simple: the system call that Berkeley DB uses to flush
+data to disk (normally <b>fsync</b>(2)), must guarantee that all the
+information necessary for a file's recoverability has been written to
+stable storage before it returns to Berkeley DB, and that no possible
+application or system crash can cause that file to be unrecoverable.
+<p>In addition, Berkeley DB implicitly uses the interface between the operating
+system and the underlying hardware.  The interface requirements here are
+not as simple.
+<p>First, it is necessary to consider the underlying page size of the Berkeley DB
+databases.  The Berkeley DB library performs all database writes using the page
+size specified by the application.  These pages are not checksummed and
+Berkeley DB assumes that they are written atomically.  This means that if the
+operating system performs filesystem I/O in different sized blocks than
+the database page size, it may increase the possibility for database
+corruption.  For example, assume that Berkeley DB is writing 32KB pages for a
+database and the operating system does filesystem I/O in 16KB blocks.  If
+the operating system writes the first 16KB of the database page
+successfully, but crashes before being able to write the second 16KB of
+the database, the database has been corrupted and this corruption will
+not be detected during recovery.  For this reason, it may be important
+to select database page sizes that will be written as single block
+transfers by the underlying operating system.
+<p>Second, it is necessary to consider the behavior of the system's underlying
+stable storage hardware.  For example, consider a SCSI controller that
+has been configured to cache data and return to the operating system that
+the data has been written to stable storage, when, in fact, it has only
+been written into the controller RAM cache.  If power is lost before the
+controller is able to flush its cache to disk, and the controller cache
+is not stable (i.e., the writes will not be flushed to disk when power
+returns), the writes will be lost.  If the writes include database blocks,
+there is no loss as recovery will correctly update the database.  If the
+writes include log file blocks, it is possible that transactions that were
+already committed may not appear in the recovered database, although the
+recovered database will be coherent after a crash.
+<p>If the underlying hardware can fail in any way such that only part of the
+block was written, the failure conditions are the same as those described
+above for an operating system failure that only writes part of a logical
+database block.
+<p>For these reasons, it is important to select hardware that does not do
+partial writes and does not cache data writes (or does not return that
+the data has been written to stable storage until it either has been
+written to stable storage or the actual writing of all of the data is
+guaranteed barring catastrophic hardware failure, e.g., your disk drive
+exploding).  You should also be aware that Berkeley DB does not protect against
+all cases of stable storage hardware failure, nor does it protect against
+hardware misbehavior.
+<p>If the disk drive on which you are storing your databases explodes, you
+can perform normal Berkeley DB catastrophic recovery, as that requires only a
+snapshot of your databases plus all of the log files you have archived
+since those snapshots were taken.  In this case, you will lose no database
+changes at all.  If the disk drive on which you are storing your log files
+explodes, you can still perform catastrophic recovery, but you will lose
+any database changes that were part of transactions committed since your
+last archival of the log files.  For this reason, storing your databases
+and log files on different disks should be considered a safety measure as
+well as a performance enhancement.
+<p>Finally, if your hardware misbehaves, for example, a SCSI controller
+writes incorrect data to the disk, Berkeley DB will not detect this and your
+data may be corrupted.

+<h1 align=center>Recovery procedures</h1>
+<p>The fifth component of the infrastructure, recovery procedures, concerns
+the recoverability of the database.  After any application or system
+failure, there are two possible approaches to database recovery:
+<p><ol>
+<p><li>There is no need for recoverability and all databases can be recreated
+from scratch.  While these applications may still need transaction
+protection for other reasons, recovery usually consists of removing the
+Berkeley DB environment home directory and all files it contains, and then
+restarting the application.
+<p><li>It is necessary to recover information after system or application
+failure.  In this case, recovery processing must be performed on any
+database environments that were active at the time of the failure.
+Recovery processing involves running the <a href="../../utility/db_recover.html">db_recover</a> utility or
+calling the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function with the <a href="../../api_c/env_open.html#DB_RECOVER">DB_RECOVER</a> or
+<a href="../../api_c/env_open.html#DB_RECOVER_FATAL">DB_RECOVER_FATAL</a> flags.
+<p>During recovery processing, all database changes made by aborted or
+unfinished transactions are undone and all database changes made by
+committed transactions are redone, as necessary.  Database applications
+must not be restarted until recovery completes.  After recovery
+finishes, the environment is properly initialized so that applications
+may be restarted.
+</ol>
+<p>If you intend to do recovery, there are two possible types of recovery
+processing:
+<p><ol>
+<p><li><i>catastrophic</i> recovery.  A failure that requires catastrophic
+recovery is a failure where either the database or log files have been
+destroyed or corrupted.  For example, catastrophic failure includes the
+case where the disk drive on which either the database or logs are
+stored has been physically destroyed, or when the system's normal
+filesystem recovery on startup is unable to bring the database and log
+files to a consistent state.  This is often difficult to detect, and
+perhaps the most common sign of the need for catastrophic recovery is
+when the normal recovery procedures fail.
+<p>To restore your database environment after catastrophic failure, take
+the following steps:
+<p><ol>
+<p><li>Restore the most recent snapshots of the database and log files from
+the backup media into the system directory where recovery will be
+performed.
+<p><li>If any log files were archived since the last snapshot was made, they
+should be restored into the Berkeley DB environment directory where recovery
+will be performed.  Make sure you restore them in the order in which
+they were written.  The order is important because it's possible that
+the same log file appears on multiple backups and you want to run
+recovery using the most recent version of each log file.
+<p><li>Run the <a href="../../utility/db_recover.html">db_recover</a> utility, specifying its <b>-c</b> option,
+or call the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function specifying the <a href="../../api_c/env_open.html#DB_RECOVER_FATAL">DB_RECOVER_FATAL</a>
+flag.  The catastrophic recovery process will review the logs and
+database files to bring the environment databases to a consistent state
+as of the time of the last uncorrupted log file that is found.  It is
+important to realize that only transactions committed before that date
+will appear in the databases.
+<p>It is possible to recreate the database in a location different than
+the original, by specifying appropriate pathnames to the <b>-h</b>
+option of the <a href="../../utility/db_recover.html">db_recover</a> utility. In order for this to work
+properly, it is important that your application reference files by
+names relative to the database home directory or the pathname(s) specified
+in calls to <a href="../../api_c/env_set_data_dir.html">DBENV-&gt;set_data_dir</a>, instead of using full path names.
+</ol>
+<p><li><i>non-catastrophic</i> or <i>normal</i> recovery.  If the
+failure is non-catastrophic and the database files and log are both
+accessible on a stable filesystem, run the <a href="../../utility/db_recover.html">db_recover</a> utility
+without the <b>-c</b> option or call the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function
+specifying the <a href="../../api_c/env_open.html#DB_RECOVER">DB_RECOVER</a> flag.  The normal recovery process
+will review the logs and database files to ensure that all changes
+associated with committed transactions appear in the databases and that
+all uncommitted transactions do not.
+</ol>

+<h1 align=center>Terminology</h1>
+<p>Here are some definitions that will be helpful in understanding
+transactions:
+<p><dl compact>
+<p><dt>Thread of control<dd>Berkeley DB is indifferent to the type or style of threads being used by the
+application, or, for that matter, if threads are being used at all, as
+Berkeley DB supports multi-process access.  In the Berkeley DB documentation, any
+time we refer to a "thread of control", that can be read as a true
+thread (one of many in an application's address space), or, a process.
+<p><dt>Free-threaded<dd>A Berkeley DB handle that can be used by multiple threads simultaneously
+without any application-level synchronization is called free-threaded.
+<p><dt>Transaction<dd>A transaction is a one or more operations on one or more databases, that
+should be treated as a single unit of work.  For example, changes to a
+set of databases, where either all of the changes must be applied to
+the database(s) or none of them should.  Applications specify when each
+transaction starts, what database operations are included in it, and
+when it ends.
+<p><dt>Transaction abort/commit<dd>Every transaction ends by <i>committing</i> or <i>aborting</i>.
+If a transaction commits, then Berkeley DB guarantees that any database
+changes included in the transaction will never be lost, even after
+system or application failure.  If a transaction aborts, or is
+uncommitted when the system or application fails, then the changes
+involved will never appear in the database.
+<p><dt>System or application failure<dd>This is the phrase that we will use to describe when something bad
+happens near your data.  It can be an application dumping core, being
+interrupted by a signal, the disk filling up, or the entire system
+crashing.  In any case, for whatever reason, the application can no
+longer make forward progress, and its databases were left in an unknown
+state.
+<p><dt>Recovery<dd>Whenever system or application failure occurs, the application must run
+recovery.  Recovery is what makes the database consistent, that is, the
+recovery process includes review of log files and databases to ensure
+that the changes from each committed transaction appear in the database,
+and that no changes from an unfinished (or aborted) transaction do.
+<p><dt>Deadlock<dd>Deadlock, in its simplest form, happens when one thread of control owns
+resource A, but needs resource B, while another thread of control owns
+resource B, but needs resource A.  Neither thread of control can make
+progress, and so one has to give up and release all of its resources,
+at which time the remaining thread of control can make forward progress.

+<h1 align=center>Transaction throughput</h1>
+<p>Generally, the speed of a database system is measured by the transaction
+throughput, expressed as the number of transactions per second.  The two
+gating factors for Berkeley DB performance in a transactional system are usually
+the underlying database files and the log file.  Both are factors because
+they require disk I/O, which is slow relative to other system resources
+like CPU.
+<p>In the worst case scenario:
+<ul type=disc>
+<li>Database access is truly random and the database is too large to fit into
+the cache, resulting in a single I/O per requested key/data pair.
+<li>Both the database and the log are on a single disk.
+</ul>
+<p>This means that for each transaction, Berkeley DB is potentially performing
+several filesystem operations:
+<ul type=disc>
+<li>Disk seek to database file.
+<li>Database file read.
+<li>Disk seek to log file.
+<li>Log file write.
+<li>Flush log file information to disk.
+<li>Disk seek to update log file metadata (e.g., inode).
+<li>Log metadata write.
+<li>Flush log file metadata to disk.
+</ul>
+<p>There are a number of ways to increase transactional throughput, all of
+which attempt to decrease the number of filesystem operations per
+transaction:
+<ul type=disc>
+<li>Tune the size of the database cache.  If the Berkeley DB key/data pairs used
+during the transaction are found in the database cache, the seek and read
+from the database are no longer necessary, resulting in two fewer
+filesystem operations per transaction.  To determine if your cache size
+is too small, see <a href="../../ref/am_conf/cachesize.html">Selecting a
+cache size</a>.
+<li>Put the database and the log files on different disks.  This allows reads
+and writes to the log files and the database files to be performed
+concurrently.
+<li>Set the filesystem configuration so that file access and modification
+times are not updated.  Note, although the file access and modification
+times are not used by Berkeley DB, this may affect other programs, so be
+careful.
+<li>Upgrade your hardware.  When considering the hardware on which to run your
+application, however, it is important to consider the entire system.  The
+controller and bus can have as much to do with the disk performance as
+the disk itself.  It is also important to remember that throughput is
+rarely the limiting factor, and that disk seek times are normally the true
+performance issue for Berkeley DB.
+<li>Turn on the <a href="../../api_c/env_open.html#DB_TXN_NOSYNC">DB_TXN_NOSYNC</a> flag.  This changes the Berkeley DB behavior
+so that the log files are not flushed when transactions are committed.
+While this change will greatly increase your transaction throughput, it
+means that transactions will exhibit the ACI (atomicity, consistency and
+isolation) properties, but not D (durability).  Database integrity will
+be maintained but it is possible that some number of the most recently
+committed transactions may be undone during recovery instead of being
+redone.
+</ul>
+<p>If you are bottlenecked on logging, the following test will help you
+confirm that the number of transactions per second that your application
+does is reasonable for the hardware on which you're running.  Your test
+program should repeatedly perform the following operations:
+<ul type=disc>
+<li>Seek to the beginning of a file.
+<li>Write to the file.
+<li>Flush the file write to disk.
+</ul>
+<p>The number of times that you can perform these three operations per second
+is a rough measure of the number of transactions per second of which the
+hardware is capable.  This test simulates the operations applied to the
+log file. (As a simplifying assumption in this experiment, we assume that
+the database files are either on a separate disk, or that they fit, with
+some few exceptions, into the database cache.)  We do not have to directly
+simulate updating the log file directory information, as it will normally
+be updated and flushed to disk as a result of flushing the log file write
+to disk.
+<p>Running this test program, where we write 256 bytes, for 1000 operations,
+on reasonably standard commodity hardware (Pentium II CPU, SCSI disk),
+returned the following results:
+<p><blockquote><pre>% testfile -b256 -o1000
+running: 1000 ops
+Elapsed time: 16.641934 seconds
+1000 ops:   60.09 ops per second</pre></blockquote>
+<p>Note that the number of bytes being written to the log as part of each
+transaction can dramatically affect the transaction throughput.  The
+above test run used 256, which is a reasonable size log write.  Your
+log writes may be different.  To determine your average log write size,
+use the <a href="../../utility/db_stat.html">db_stat</a> utility to display your log statistics.
+<p>As a quick sanity check, for this particular disk, the average seek time
+is 9.4 msec, and the average latency is 4.17 msec.  That results in a
+minimum requirement for a data transfer to the disk of 13.57 msec, or a
+maximum of 74 transfers per second.  This is close enough to the above 60
+operations per second (which wasn't done on a quiescent disk) that the
+number is believable.
+<p>An implementation of the above <a href="writetest.txt">example test
+program</a> for IEEE/ANSI Std 1003.1 (POSIX) standard systems is included in the Berkeley DB
+distribution.

+<p>
+<h1 align=center>Why transactions?</h1>
+<p>Perhaps the first question to answer is "Why transactions?"  There are
+a number of reasons for including transactional support in your
+applications.  The most common ones are:
+<p><dl compact>
+<p><dt>Recoverability<dd>Applications often need to ensure that, no matter how the system or
+application fails, previously saved data is available the next time the
+application runs.
+<p><dt>Deadlock avoidance<dd>When multiple threads of control change the database at the same time,
+there is usually the possibility of deadlock, that is, where each of
+the threads of control owns a resource another thread wants, and so no
+thread is able to make forward progress, all waiting for a resource.
+Deadlocks are resolved by having one of the operations involved release
+the resources it controls so the other operations can proceed.  (The
+operation releasing its resources usually just tries again later.)
+Transactions are necessary so that any changes that were already made
+to the database can be undone as part of releasing the held resources.
+<p><dt>Atomicity<dd>Applications often need to make multiple changes to one or more
+databases, but want to ensure that either all of the changes happen, or
+none of them happen.  Transactions guarantee that a group of changes
+are atomic, that is, if the application or system fails, either all of
+the changes to the databases will appear when the application next runs,
+or none of them.
+<p><dt>Repeatable reads<dd>Applications sometimes need to ensure that, while doing a group of
+operations on a database, the value returned as a result of a database
+retrieval doesn't change, that is, if you retrieve the same key more
+than once, the data item will be the same each time.  Transactions
+guarantee this behavior.

+<h1 align=center>Berkeley DB and transactions</h1>
+<p>The transaction subsystem makes operations atomic, consistent, isolated,
+and durable in the face of system and application failures.  The subsystem
+requires that the data be properly logged and locked in order to attain
+these properties.  Berkeley DB contains all the components necessary to
+transaction-protect the Berkeley DB access methods and other forms of data may
+be protected if they are logged and locked appropriately.
+<p>The transaction subsystem is created, initialized, and opened by calls to
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> with the <a href="../../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a> flag specified.  Note that
+enabling transactions automatically enables logging, but does not enable
+locking, as a single thread of control that needed atomicity and
+recoverability would not require it.
+<p>The <a href="../../api_c/txn_begin.html">txn_begin</a> function starts a transaction, returning an opaque
+handle to a transaction.  If the parent parameter to <a href="../../api_c/txn_begin.html">txn_begin</a> is
+non-NULL, then the new transaction is a child of the designated parent
+transaction.
+<p>The <a href="../../api_c/txn_abort.html">txn_abort</a> function ends the designated transaction and causes
+all updates performed by the transaction to be undone.  The end result is
+that the database is left in a state identical to the state that existed
+prior to the <a href="../../api_c/txn_begin.html">txn_begin</a>.  If the aborting transaction has any child
+transactions associated with it (even ones that have already been
+committed), they are also aborted.  Any transactions that are unresolved
+(i.e., neither committed nor aborted) when the application or system fails
+are aborted during recovery.
+<p>The <a href="../../api_c/txn_commit.html">txn_commit</a> function ends the designated transaction and makes
+all the updates performed by the transaction permanent, even in the face
+of application or system failure.  If this is a parent transaction
+committing, then all child transactions that individually committed or
+had not been resolved are also committed.
+<p>Transactions are identified by 32-bit unsigned integers.  The ID
+associated with any transaction can be obtained using the <a href="../../api_c/txn_id.html">txn_id</a>
+function.  If an application is maintaining information outside of Berkeley DB
+that it wishes to transaction-protect, it should use this transaction ID
+as the locking ID.
+<p>The <a href="../../api_c/txn_checkpoint.html">txn_checkpoint</a> function causes a transaction checkpoint.  A
+checkpoint is performed relative to a specific log sequence number (LSN),
+referred to as the checkpoint LSN.  When a checkpoint completes
+successfully, it means that all data buffers whose updates are described
+by LSNs less than the checkpoint LSN have been written to disk.  This, in
+turn, means that the log records less than the checkpoint LSN are no
+longer necessary for normal recovery (although they would be required for
+catastrophic recovery should the database files be lost) and all log files
+containing only records prior to the checkpoint LSN may be safely archived
+and removed.
+<p>It is possible that in order to complete a transaction checkpoint, it will
+be necessary to write a buffer that is currently in use (i.e., is actively
+being read or written by some transaction).  In this case,
+<a href="../../api_c/txn_checkpoint.html">txn_checkpoint</a> will not be able to write the buffer, as doing so
+might cause an inconsistent version of the page to be written to disk,
+and instead of completing successfully will return with an error code of
+<a href="../../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a>.  In such cases, the checkpoint can simply be
+retried after a short delay.
+<p>The interval between successive checkpoints is directly proportional to
+the length of time required to run normal recovery.  If the interval

+<h1 align=center>Transaction limits</h1>
+<h3>Transaction IDs</h3>
+<p>Transactions are identified uniquely by 32-bit unsigned integers.  The
+high-order bit of the transaction ID is reserved (and defined to be 1)
+resulting in just over two billion unique transaction IDs.  Each time
+that recovery is run, the beginning transaction ID is reset with new
+transactions being numbered starting from 1.  This means that recovery
+must be run at least once every two billion transactions.
+<p>It is possible that some environments may need to be aware of this
+limitation.  Consider an application performing 600 transactions a second
+for 15 hours a day.  The transaction ID space will run out in roughly 66
+days:
+<p><blockquote><pre>2^31 / (600 * 15 * 60 * 60) = 66</pre></blockquote>
+<p>Doing only 100 transactions a second exhausts the transaction ID space
+in roughly one year.
+<p>The transaction ID name space is initialized each time
+a database environment is created or recovered.  If you
+reach the end of the transaction ID name space, it must
+be handled as if an application or system failure had
+occurred.  The most recently allocated transaction ID
+is the <b>st_last_txnid</b> value in the transaction
+statistics information, and is displayed by the
+<a href="../../utility/db_stat.html">db_stat</a> utility.
+<h3>Cursors</h3>
+<p>When using transactions, cursors are localized to a single transaction.
+That is, a cursor may not span transactions and must be opened and
+closed within a single transaction.  In addition, intermingling
+transaction-protected cursor operations and non-transaction-protected
+cursor operations on the same database in a single thread of control is
+practically guaranteed to deadlock as the locks obtained for transactions
+and non-transactions can conflict.
+<h3>Multiple Threads of Control</h3>
+<p>Since transactions must hold all their locks until commit, a single
+transaction may accumulate a large number of long-term locks during its
+lifetime.  As a result, when two concurrently running transactions access
+the same database, there is strong potential for conflict.  While Berkeley
+DB allows an application to have multiple outstanding transactions active
+within a single thread of control, great care must be taken to ensure that
+the transactions do not interfere with each other (e.g., attempt to obtain
+conflicting locks on the same data).  If two concurrently active
+transactions in the same thread of control do encounter a lock conflict,
+the thread of control will deadlock in such a manner that the deadlock
+detector will be unable to resolve the problem.  In this case, there is
+no true deadlock, but because the transaction on which a transaction is
+waiting is in the same thread of control, no forward progress can be made.

+<h1 align=center>Nested transactions</h1>
+<p>Berkeley DB provides support for nested transactions.  Nested transactions
+allow an application to decompose a large or long-running transaction
+into smaller units that may be independently aborted.
+<p>Normally, when beginning a transaction, the application will pass a NULL
+value for the parent argument to <a href="../../api_c/txn_begin.html">txn_begin</a>.  If, however, the
+parent argument is a DB_TXN handle, then the newly created
+transaction will be treated as a nested transaction within the parent.
+Transactions may nest arbitrarily deeply.  For the purposes of this
+discussion, transactions created with a parent identifier will be called
+child transactions.
+<p>Once a transaction becomes a parent, as long as any of its child
+transactions are unresolved (i.e., they have neither committed nor
+aborted), the parent may not issue any Berkeley DB calls except to begin more
+child transactions or to commit or abort.  That is, it may not issue
+any access method or cursor calls.  Once all of a parent's children have
+committed or aborted, the parent may again request operations on its
+own behalf.
+<p>The semantics of nested transactions are as follows.  When a child
+transaction is begun, it inherits all the locks of its parent.  This
+means that the child will never block waiting on a lock held by its
+parent.  However, if a parent attempts to obtain locks after they have
+begun a child, the parental locks can conflict with those held by a
+child.  Furthermore, locks held by two different children will also
+conflict.  To make this concrete, consider the following set of
+transactions and lock acquisitions.
+<p>Transaction T1 is the parent transaction.  It acquires an exclusive lock
+on item A and then begins two child transactions, C1 and C2.  C1 also
+wishes to acquire a write lock on A; this succeeds.  Now, let's say that
+C1 acquires a write lock on B.  If C2 now attempts to obtain a lock on
+B, it will block.  However, let's now assume that C1 commits.  Its locks
+are anti-inherited, which means they are now given to T1.  At this
+point, either T1 or C2 is allowed to acquire a lock on B.  If, however,
+transaction T1 aborts, then its locks are released.  Future requests by
+T1 or C2 will also succeed, but they will be obtaining new locks as
+opposed to piggy-backing off a lock already held by T1.
+<p>Child transactions are entirely subservient to their parent transaction.
+They may abort, undoing their operations regardless of the eventual fate
+of the parent.  However, even if a child transaction commits, if its
+parent transaction is eventually aborted, the child's changes are undone
+and the child's transaction is effectively aborted.  Any child
+transactions that are not yet resolved when the parent commits or aborts
+are resolved based on the parent's resolution, committing if the parent
+commits and aborting if the parent aborts.  Any child transactions that
+are not yet resolved when the parent prepares are also prepared.

+<h1 align=center>Transactions and non-Berkeley DB applications</h1>
+<p>It is possible to use the locking, logging and transaction subsystems
+of Berkeley DB to provide transaction semantics on objects other than those
+described by the Berkeley DB access methods.  In these cases, the application
+will need more explicit customization of the subsystems as well as the
+development of appropriate data-structure-specific recovery functions.
+<p>For example, consider an application that provides transaction semantics
+on data stored in plain UNIX files accessed using the POSIX read and write
+system calls.  The operations for which transaction protection is desired
+are bracketed by calls to <a href="../../api_c/txn_begin.html">txn_begin</a> and <a href="../../api_c/txn_commit.html">txn_commit</a>.
+<p>Before data are referenced, the application must make a call to the lock
+manager, <a href="../../api_c/lock_get.html">lock_get</a>, for a lock of the appropriate type (e.g.,
+read) on the object being locked.  The object might be a page in the file,
+a byte, a range of bytes, or some key.  It is up to the application to
+ensure that appropriate locks are acquired.  Before a write is performed,
+the application should acquire a write lock on the object, by making an
+appropriate call to the lock manager, <a href="../../api_c/lock_get.html">lock_get</a>.  Then, the
+application should make a call to the log manager, <a href="../../api_c/log_put.html">log_put</a>, to
+record enough information to redo the operation in case of failure after
+commit and to undo the operation in case of abort.
+<p>It is important, when designing applications that will use the log
+subsystem, to remember that the application is responsible for providing
+any necessary structure to the log record.  For example, the application
+must understand what part of the log record is an operation code, what
+part identifies the file being modified, what part is redo information,
+and what part is undo information.
+<p>After the log message is written, the application may issue the write
+system call.  After all requests are issued, the application may call
+<a href="../../api_c/txn_commit.html">txn_commit</a>.  When <a href="../../api_c/txn_commit.html">txn_commit</a> returns, the caller is
+guaranteed that all necessary log writes have been written to disk.
+<p>At any time, the application may call <a href="../../api_c/txn_abort.html">txn_abort</a>, which will result
+in restoration of the database to a consistent pre-transaction state.
+(The application may specify its own recovery function for this purpose
+using the <a href="../../api_c/env_set_tx_recover.html">DBENV-&gt;set_tx_recover</a> function.  The recovery function must be
+able to either re-apply or undo the update depending on the context, for
+each different type of log record.)
+<p>If the application should crash, the recovery process uses the log to
+restore the database to a consistent state.
+<p>The <a href="../../api_c/txn_prepare.html">txn_prepare</a> function provides the core functionality to
+implement distributed transactions, but it does not manage the
+notification of distributed transaction managers.  The caller is
+responsible for issuing <a href="../../api_c/txn_prepare.html">txn_prepare</a> calls to all sites
+participating in the transaction.  If all responses are positive, the
+caller can issue a <a href="../../api_c/txn_commit.html">txn_commit</a>.  If any of the responses are
+negative, the caller should issue a <a href="../../api_c/txn_abort.html">txn_abort</a>.  In general, the
+<a href="../../api_c/txn_prepare.html">txn_prepare</a> call requires that the transaction log be flushed to
+disk.

+<h1 align=center>Release 2.0: converting applications</h1>
+<p>Mapping the Berkeley DB 1.85 functionality into Berkeley DB version 2 is almost always
+simple.  The manual page <a href="../../api_c/db_open.html">DB-&gt;open</a> replaces the Berkeley DB 1.85 manual
+pages <b>dbopen</b>(3), <b>btree</b>(3), <b>hash</b>(3) and
+<b>recno</b>(3).  You should be able to convert each 1.85 function
+call into a Berkeley DB version 2 function call using just the <a href="../../api_c/db_open.html">DB-&gt;open</a>
+documentation.
+<p>Some guidelines and things to watch out for:
+<p><ol>
+<p><li>Most access method functions have exactly the same semantics as in Berkeley DB
+1.85, although the arguments to the functions have changed in some cases.
+To get your code to compile, the most common change is to add the
+transaction ID as an argument (NULL, since Berkeley DB 1.85 did not support
+transactions.)
+<p><li>You must always initialize DBT structures to zero before using them with
+any Berkeley DB version 2 function.  (They do not normally have to be
+reinitialized each time, only when they are first allocated.  Do this by
+declaring the DBT structure external or static, or by calling the C
+library routine <b>bzero</b>(3) or <b>memset</b>(3).)
+<p><li>The error returns are completely different in the two versions.  In Berkeley DB
+1.85, &lt; 0 meant an error, and &gt; 0 meant a minor Berkeley DB exception.
+In Berkeley DB 2.0, &gt; 0 means an error (the Berkeley DB version 2 functions
+return <b>errno</b> on error) and &lt; 0 means a Berkeley DB exception.
+See <a href="../../ref/program/errorret.html">Error Returns to Applications</a>
+for more information.
+<p><li>The Berkeley DB 1.85 DB-&gt;seq function has been replaced by cursors in Berkeley DB
+version 2.  The semantics are approximately the same, but cursors require
+the creation of an extra object (the DBC object), which is then used to
+access the database.
+<p>Specifically, the partial key match and range search functionality of the
+R_CURSOR flag in DB-&gt;seq has been replaced by the
+<a href="../../api_c/dbc_get.html#DB_SET_RANGE">DB_SET_RANGE</a> flag in <a href="../../api_c/dbc_get.html">DBcursor-&gt;c_get</a>.
+<p><li>In version 2 of the Berkeley DB library, additions or deletions into Recno
+(fixed and variable-length record) databases no longer automatically
+logically renumber all records after the add/delete point, by default.
+The default behavior is that deleting records does not cause subsequent
+records to be renumbered, and it is an error to attempt to add new records
+between records already in the database.  Applications wanting the
+historic Recno access method semantics should call the
+<a href="../../api_c/db_set_flags.html">DB-&gt;set_flags</a> function with the <a href="../../api_c/db_set_flags.html#DB_RENUMBER">DB_RENUMBER</a> flag.
+<p><li>Opening a database in Berkeley DB version 2 is a much heavier-weight operation
+than it was in Berkeley DB 1.85.  Therefore, if your historic applications were
+written to open a database, perform a single operation, and close the
+database, you may observe performance degradation.  In most cases, this
+is due to the expense of creating the environment upon each open.   While
+we encourage restructuring your application to avoid repeated opens and
+closes, you can probably recover most of the lost performance by simply
+using a persistent environment across invocations.
+</ol>
+<p>While simply converting Berkeley DB 1.85 function calls to Berkeley DB version 2
+function calls will work, we recommend that you eventually reconsider your
+application's interface to the Berkeley DB database library in light of the
+additional functionality supplied by Berkeley DB version 2, as it is likely to
+result in enhanced application performance.

+<h1 align=center>Release 2.0: system integration</h1>
+<p><ol>
+<p><li>It is possible to maintain both the Berkeley DB 1.85 and Berkeley DB version 2
+libraries on your system.  However, the <b>db.h</b> include file that
+was distributed with Berkeley DB 1.85 is not compatible with the <b>db.h</b>
+file distributed with Berkeley DB version 2, so you will have to install them
+in different locations.  In addition, both the Berkeley DB 1.85 and Berkeley DB
+version 2 libraries are named <b>libdb.a</b>.
+<p>As the Berkeley DB 1.85 library did not have an installation target in the
+Makefile, there's no way to know exactly where it was installed on the
+system.  In addition, many vendors included it in the C library instead
+of as a separate library, and so it may actually be part of libc and the
+<b>db.h</b> include file may be installed in <b>/usr/include</b>.
+<p>For these reasons, the simplest way to maintain both libraries is to
+install Berkeley DB version 2 in a completely separate area of your system.
+The Berkeley DB version 2 installation process allows you to install into a
+standalone directory hierarchy on your system.  See the
+<a href="../../ref/build_unix/intro.html">Building for UNIX systems</a>
+documentation for more information and instructions on how to install the
+Berkeley DB version 2 library, include files and documentation into specific
+locations.
+<p><li>Alternatively, you can replace Berkeley DB 1.85 on your system with Berkeley DB
+version 2.  In this case, you'll probably want to install Berkeley DB version
+2 in the normal place on your system, wherever that may be, and delete
+the Berkeley DB 1.85 include files, manual pages and libraries.
+<p>To replace 1.85 with version 2, you must either convert your 1.85
+applications to use the version 2 API or build the Berkeley DB version 2 library
+to include Berkeley DB 1.85 interface compatibility code.  Whether converting
+your applications to use the version 2 interface or using the version 1.85
+compatibility API, you will need to recompile or relink your 1.85
+applications, and you must convert any persistent application databases
+to the Berkeley DB version 2 database formats.
+<p>If you want to recompile your Berkeley DB 1.85 applications, you will have to
+change them to include the file <b>db_185.h</b> instead of
+<b>db.h</b>.  (The <b>db_185.h</b> file is automatically installed
+during the Berkeley DB version 2 installation process.)  You can then recompile
+the applications, linking them against the Berkeley DB version 2 library.
+<p>For more information on compiling the Berkeley DB 1.85 compatibility code into
+the Berkeley DB version 2 library, see <a href="../../ref/build_unix/intro.html">Building for UNIX platforms</a>.
+<p>For more information on converting databases from the Berkeley DB 1.85 formats
+to the Berkeley DB version 2 formats, see the <a href="../../utility/db_dump.html">db_dump185</a> and
+<a href="../../utility/db_load.html">db_load</a> documentation.
+<p><li>Finally, although we certainly do not recommend it, it is possible to
+load both Berkeley DB 1.85 and Berkeley DB version 2 into the same library.
+Similarly, it is possible to use both Berkeley DB 1.85 and Berkeley DB version 2
+within a single application, although it is not possible to use them from
+within the same file.
+<p>The name space in Berkeley DB version 2 has been changed from that of previous
+Berkeley DB versions, notably version 1.85, for portability and consistency
+reasons.  The only name collisions in the two libraries are the names used
+by the historic <a href="../../api_c/dbm.html">dbm</a>, <a href="../../api_c/dbm.html">ndbm</a> and <a href="../../api_c/hsearch.html">hsearch</a> interfaces,
+and the Berkeley DB 1.85 compatibility interfaces in the Berkeley DB version 2
+library.
+<p>If you are loading both Berkeley DB 1.85 and Berkeley DB version 2 into a single
+library, remove the historic interfaces from one of the two library
+builds, and configure the Berkeley DB version 2 build to not include the Berkeley DB
+1.85 compatibility API, otherwise you could have collisions and undefined
+behavior.  This can be done by editing the library Makefiles and
+reconfiguring and rebuilding the Berkeley DB version 2 library.  Obviously, if
+you use the historic interfaces, you will get the version in the library
+from which you did not remove them.  Similarly, you will not be able to
+access Berkeley DB version 2 files using the Berkeley DB 1.85 compatibility interface,
+since you have removed that from the library as well.

+<p>The Db::set_error_model method is gone.  The way to change the C++ API to

+Db constructor.  For example:
+<p><blockquote><pre>int dberr;

+<p>creates an environment that will never throw exceptions, and method
+returns should be checked instead.
+<p>There are a number of smaller changes to the API that bring the C, C++
+and Java APIs much closer in terms of functionality and usage.  Please
+refer to the pages for upgrading C applications for further details.

+<h1 align=center>Release 3.0: the Db class for C++ and Java</h1>
+<p>The static Db::open method and the DbInfo class have been removed in the
+Berkeley DB 3.0 release.  The way to open a database file is to use the new Db
+constructor with two arguments, followed by set_XXX methods to configure
+the Db object, and finally a call to the new (nonstatic) Db::open().  In
+comparing the Berkeley DB 3.0 release open method with the 2.X static open
+method, the second argument is new.  It is a database name, which can
+be null.  The DbEnv argument has been removed, as the environment is now
+specified in the constructor.  The open method no longer returns a Db,
+since it operates on one.
+<p>Here's a C++ example opening a Berkeley DB database using the 2.X interface:
+<p><blockquote><pre>// Note: by default, errors are thrown as exceptions
+Db *table;
+Db::open("lookup.db", DB_BTREE, DB_CREATE, 0644, dbenv, 0, &table);</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code would be written as:
+<p><blockquote><pre>// Note: by default, errors are thrown as exceptions
+Db *table = new Db(dbenv, 0);
+table-&gt;open("lookup.db", NULL, DB_BTREE, DB_CREATE, 0644);</pre></blockquote>
+<p>Here's a Java example opening a Berkeley DB database using the 2.X interface:
+<p><blockquote><pre>// Note: errors are thrown as exceptions
+Db table = Db.open("lookup.db", Db.DB_BTREE, Db.DB_CREATE, 0644, dbenv, 0);</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code would be written as:
+<p><blockquote><pre>// Note: errors are thrown as exceptions
+Db table = new Db(dbenv, 0);
+table.open("lookup.db", null, Db.DB_BTREE, Db.DB_CREATE, 0644);</pre></blockquote>
+<p>Note that if the dbenv argument is  null, the database will not exist
+within an environment.

+<h1 align=center>Release 3.0: the DbEnv class for C++ and Java</h1>
+<p>The DbEnv::appinit() method and two constructors for the DbEnv class are
+gone.  There is now a single way to create and initialize the environment.
+The way to create an environment is to use the new DbEnv constructor with
+one argument.  After this call, the DbEnv can be configured with various
+set_XXX methods.  Finally, a call to DbEnv::open is made to initialize
+the environment.
+<p>Here's a C++ example creating a Berkeley DB environment using the 2.X interface
+<p><blockquote><pre>int dberr;
+DbEnv *dbenv = new DbEnv();
+<p>
+dbenv-&gt;set_error_stream(&cerr);
+dbenv-&gt;set_errpfx("myprog");
+<p>
+if ((dberr = dbenv-&gt;appinit("/database/home",
+	NULL, DB_CREATE | DB_INIT_LOCK | DB_INIT_MPOOL)) != 0) {
+    cerr &lt;&lt; "failure: " &lt;&lt; strerror(dberr);
+    exit (1);
+}</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code would be written as:
+<p><blockquote><pre>int dberr;
+DbEnv *dbenv = new DbEnv(0);
+<p>
+dbenv-&gt;set_error_stream(&cerr);
+dbenv-&gt;set_errpfx("myprog");
+<p>
+if ((dberr = dbenv-&gt;open("/database/home",
+	NULL, DB_CREATE | DB_INIT_LOCK | DB_INIT_MPOOL, 0)) != 0) {
+    cerr &lt;&lt; "failure: " &lt;&lt; dbenv-&gt;strerror(dberr);
+    exit (1);
+}</pre></blockquote>
+<p>Here's a Java example creating a Berkeley DB environment using the 2.X interface:
+<p><blockquote><pre>int dberr;
+DbEnv dbenv = new DbEnv();
+<p>
+dbenv.set_error_stream(System.err);
+dbenv.set_errpfx("myprog");
+<p>
+dbenv.appinit("/database/home",
+    null, Db.DB_CREATE | Db.DB_INIT_LOCK | Db.DB_INIT_MPOOL);</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code would be written as:
+<p><blockquote><pre>int dberr;
+DbEnv dbenv = new DbEnv(0);
+<p>
+dbenv.set_error_stream(System.err);
+dbenv.set_errpfx("myprog");
+<p>
+dbenv.open("/database/home",
+    null, Db.DB_CREATE | Db.DB_INIT_LOCK | Db.DB_INIT_MPOOL, 0);</pre></blockquote>
+<p>In the Berkeley DB 2.X release, DbEnv had accessors to obtain "managers" of type
+DbTxnMgr, DbMpool, DbLog, DbTxnMgr.  If you used any of these managers,
+all their methods are now found directly in the DbEnv class.

+<h1 align=center>Release 3.0: the DBINFO structure</h1>
+<p>The DB_INFO structure has been removed from the Berkeley DB 3.0 release.
+Accesses to any fields within that structure by the application should be
+replaced with method calls on the DB handle.  The following
+example illustrates this using the historic db_cachesize structure field.
+In the Berkeley DB 2.X releases, applications could set the size of an
+underlying database cache using code similar to the following:
+<p><blockquote><pre>DB_INFO dbinfo;
+<p>
+	memset(dbinfo, 0, sizeof(dbinfo));
+	dbinfo.db_cachesize = 1024 * 1024;</pre></blockquote>
+<p>in the Berkeley DB 3.X releases, this should be done using the
+<a href="../../api_c/db_set_cachesize.html">DB-&gt;set_cachesize</a> method, as follows:
+<p><blockquote><pre>DB *db;
+int ret;
+<p>
+	ret = db-&gt;set_cachesize(db, 0, 1024 * 1024, 0);</pre></blockquote>
+<p>The DB_INFO structure is no longer used in any way by the Berkeley DB 3.0
+release, and should be removed from the application.
+<p>The following table lists the DB_INFO fields previously used by
+applications and the methods that should now be used to set
+them.  Because these calls provide configuration for the
+database open, they must precede the call to <a href="../../api_c/db_open.html">DB-&gt;open</a>.
+Calling them after the call to <a href="../../api_c/db_open.html">DB-&gt;open</a> will return an
+error.

+<h1 align=center>Release 3.0: environment open/close/unlink</h1>
+<p>The hardest part of upgrading your application from a 2.X code base to
+the 3.0 release is translating the Berkeley DB environment open, close and
+remove calls.
+<p>There were two logical changes in this part of the Berkeley DB interface.
+First, in Berkeley DB 3.0, there are no longer separate structures that
+represent each subsystem (e.g., DB_LOCKTAB or DB_TXNMGR) and an overall
+DB_ENV environment structure.  Instead there is only the
+DB_ENV structure.  This means that DB_ENV references should
+be passed around by your application instead of passing around DB_LOCKTAB
+or DB_TXNMGR references.  This is likely to be a simple change for most
+applications as few applications use the lock_XXX, log_XXX,
+memp_XXX or txn_XXX interfaces to create Berkeley DB environments.
+<p>The second change is that there are no longer separate open, close, and
+unlink interfaces to the
+Berkeley DB subsystems, e.g., in previous releases, it was possible to open a
+lock subsystem either using db_appinit or using the lock_open call.  In
+the 3.0 release the XXX_open interfaces to the subsystems have been
+removed, and subsystems must now be opened using the 3.0 replacement for the
+db_appinit call.
+<p>To upgrade your application, first find each place your application opens,
+closes and/or removes a Berkeley DB environment.  This will be code of the form:
+<p><blockquote><pre>db_appinit, db_appexit
+lock_open, lock_close, lock_unlink
+log_open, log_close, log_unlink
+memp_open, memp_close, memp_unlink
+txn_open, txn_close, txn_unlink</pre></blockquote>
+<p>Each of these groups of calls should be replaced with calls to:
+<p><blockquote><pre><a href="../../api_c/env_create.html">db_env_create</a>, <a href="../../api_c/env_open.html">DBENV-&gt;open</a>, <a href="../../api_c/env_close.html">DBENV-&gt;close</a>,
+<a href="../../api_c/env_remove.html">DBENV-&gt;remove</a></pre></blockquote>
+<p>The <a href="../../api_c/env_create.html">db_env_create</a> call and the call to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a>
+method replace the db_appinit, lock_open, log_open, memp_open and txn_open
+calls.  The <a href="../../api_c/env_close.html">DBENV-&gt;close</a> method replaces the db_appexit,
+lock_close, log_close, memp_close and txn_close calls.  The
+<a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> call replaces the lock_unlink, log_unlink,
+memp_unlink and txn_unlink calls.
+<p>Here's an example creating a Berkeley DB environment using the 2.X interface:
+<p><blockquote><pre>/*
+ * db_init --
+ *	Initialize the environment.
+ */
+DB_ENV *
+db_init(home)
+	char *home;
+{
+	DB_ENV *dbenv;
+<p>
+	if ((dbenv = (DB_ENV *)calloc(sizeof(DB_ENV), 1)) == NULL)
+		return (errno);
+<p>
+	if ((errno = db_appinit(home, NULL, dbenv,
+	    DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_INIT_TXN |
+	    DB_USE_ENVIRON)) == 0)
+		return (dbenv);
+<p>
+	free(dbenv);
+	return (NULL);
+}</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code would be written as:
+<p><blockquote><pre>/*
+ * db_init --
+ *	Initialize the environment.
+ */
+int
+db_init(home, dbenvp)
+	char *home;
+	DB_ENV **dbenvp;
+{
+	int ret;
+	DB_ENV *dbenv;
+<p>
+	if ((ret = db_env_create(&dbenv, 0)) != 0)
+		return (ret);

+	if ((ret = dbenv-&gt;open(dbenv, home, NULL,
+	    DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_INIT_TXN |
+	    DB_USE_ENVIRON, 0)) == 0) {
+		*dbenvp = dbenv;
+		return (0);
+	}
+<p>
+	(void)dbenv-&gt;close(dbenv, 0);
+	return (ret);
+}</pre></blockquote>
+<p>As you can see, the arguments to db_appinit and to <a href="../../api_c/env_open.html">DBENV-&gt;open</a> are
+largely the same.  There is some minor re-organization: the mapping is
+that arguments #1, 2, 3, and 4 to db_appinit become arguments #2, 3, 1
+and 4 to <a href="../../api_c/env_open.html">DBENV-&gt;open</a>.  There is one additional argument to
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a>, argument #5.  For backward compatibility with the 2.X
+Berkeley DB releases, simply set that argument to 0.
+<p>It is only slightly more complex to translate calls to XXX_open to the
+<a href="../../api_c/env_open.html">DBENV-&gt;open</a> method.  Here's an example of creating a lock region
+using the 2.X interface:
+<p><blockquote><pre>lock_open(dir, DB_CREATE, 0664, dbenv, &regionp);</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code would be written as:
+<p><blockquote><pre>if ((ret = db_env_create(&dbenv, 0)) != 0)
+	return (ret);
+<p>
+if ((ret = dbenv-&gt;open(dbenv,
+    dir, NULL, DB_CREATE | DB_INIT_LOCK, 0664)) == 0) {
+	*dbenvp = dbenv;
+	return (0);
+}</pre></blockquote>
+<p>Note that in this example, you no longer need the DB_LOCKTAB structure
+reference that was required in Berkeley DB 2.X releases.
+<p>The final issue with upgrading the db_appinit call is the DB_MPOOL_PRIVATE
+option previously provided for the db_appinit interface.  If your
+application is using this flag, it should almost certainly use the new
+<a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> interface. Regardless,
+you should carefully consider this change before converting to use the
+<a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag.
+<p>Translating db_appexit or XXX_close calls to <a href="../../api_c/env_close.html">DBENV-&gt;close</a> is equally
+simple.  Instead of taking a reference to a per-subsystem structure such
+as DB_LOCKTAB or DB_TXNMGR, all calls take a reference to a DB_ENV
+structure.  The calling sequence is otherwise unchanged.  Note that as
+the application no longer allocates the memory for the DB_ENV structure,
+application code to discard it after the call to db_appexit() is no longer
+needed.
+<p>Translating XXX_unlink calls to <a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> is slightly more complex.
+As with <a href="../../api_c/env_close.html">DBENV-&gt;close</a>, the call takes a reference to a DB_ENV
+structure instead of a per-subsystem structure.  The calling sequence is
+slightly different, however.  Here is an example of removing a lock region
+using the 2.X interface:
+<p><blockquote><pre>DB_ENV *dbenv;
+<p>
+ret = lock_unlink(dir, 1, dbenv);</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code fragment would be written as:
+<p><blockquote><pre>DB_ENV *dbenv;
+<p>
+ret = dbenv-&gt;remove(dbenv, dir, NULL, DB_FORCE);</pre></blockquote>
+<p>The additional argument to the <a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> function is a
+configuration argument similar to that previously taken by db_appinit and
+now taken by the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> method.  For backward compatibility
+this new argument should simply be set to NULL.  The force argument to
+XXX_unlink is now a flag value that is set by bitwise inclusively <b>OR</b>'ing it the
+<a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> flag argument.

+<h1 align=center>Release 3.0: function arguments</h1>
+<p>In Berkeley DB 3.0, there are no longer separate structures that
+represent each subsystem (e.g., DB_LOCKTAB or DB_TXNMGR), and an overall
+DB_ENV environment structure.  Instead there is only the
+DB_ENV structure.  This means that DB_ENV references should
+be passed around by your application instead of passing around DB_LOCKTAB
+or DB_TXNMGR references.
+<p>Each of the following functions:
+<p><blockquote><pre>lock_detect
+lock_get
+lock_id
+lock_put
+lock_stat
+lock_vec</pre></blockquote>
+<p>should have its first argument, a reference to the DB_LOCKTAB structure,
+replaced with a reference to the enclosing DB_ENV structure.  For
+example, the following line of code from a Berkeley DB 2.X application:
+<p><blockquote><pre>DB_LOCKTAB *lt;
+DB_LOCK lock;
+	ret = lock_put(lt, lock);</pre></blockquote>
+<p>should now be written as follows:
+<p><blockquote><pre>DB_ENV *dbenv;
+DB_LOCK *lock;
+	ret = lock_put(dbenv, lock);</pre></blockquote>
+<p>Similarly, all of the functions:
+<p><blockquote><pre>log_archive
+log_compare
+log_file
+log_flush
+log_get
+log_put
+log_register
+log_stat
+log_unregister</pre></blockquote>
+<p>should have their DB_LOG argument replaced with a reference to a
+DB_ENV structure, and the functions:
+<p><blockquote><pre>memp_fopen
+memp_register
+memp_stat
+memp_sync
+memp_trickle</pre></blockquote>
+<p>should have their DB_MPOOL argument replaced with a reference to a
+DB_ENV structure.
+<p>You should remove all references to DB_LOCKTAB, DB_LOG, DB_MPOOL, and
+DB_TXNMGR structures from your application, they are no longer useful
+in any way.  In fact, a simple way to identify all of the places that
+need to be upgraded is to remove all such structures and variables
+they declare, and then compile.  You will see a warning message from
+your compiler in each case that needs to be upgraded.

+<p>There are several additional types of exceptions thrown in the Berkeley DB 3.0
+Java API.
+<p>DbMemoryException and DbDeadlockException can be caught independently of
+DbException if you want to do special handling for these kinds of errors.
+Since they are subclassed from DbException, a try block that catches
+DbException will catch these also, so code is not required to change.
+The catch clause for these new exceptions should appear before the catch
+clause for DbException.
+<p>You will need to add a catch clause for java.io.FileNotFoundException,
+since that can be thrown by the <a href="../../api_java/db_open.html">Db.open</a> and <a href="../../api_java/env_open.html">DbEnv.open</a> functions.
+<p>There are a number of smaller changes to the API that bring the C, C++
+and Java APIs much closer in terms of functionality and usage.  Please
+refer to the pages for upgrading C applications for further details.

+<h1 align=center>Release 3.0: database open/close</h1>
+<p>Database opens were changed in the Berkeley DB 3.0 release in a similar way to
+environment opens.
+<p>To upgrade your application, first find each place your application opens
+a database, that is, calls the db_open function.  Each of these calls
+should be replaced with calls to <a href="../../api_c/db_create.html">db_create</a> and <a href="../../api_c/db_open.html">DB-&gt;open</a>.
+<p>Here's an example creating a Berkeley DB database using the 2.X interface:
+<p><blockquote><pre>DB *dbp;
+DB_ENV *dbenv;
+int ret;
+<p>
+if ((ret = db_open(DATABASE,
+    DB_BTREE, DB_CREATE, 0664, dbenv, NULL, &dbp)) != 0)
+	return (ret);</pre></blockquote>
+<p>In the Berkeley DB 3.0 release, this code would be written as:
+<p><blockquote><pre>DB *dbp;
+DB_ENV *dbenv;
+int ret;
+<p>
+if ((ret = db_create(&dbp, dbenv, 0)) != 0)
+	return (ret);
+<p>
+if ((ret = dbp-&gt;open(dbp,
+    DATABASE, NULL, DB_BTREE, DB_CREATE, 0664)) != 0) {
+	(void)dbp-&gt;close(dbp, 0);
+	return (ret);
+}</pre></blockquote>
+<p>As you can see, the arguments to db_open and to <a href="../../api_c/db_open.html">DB-&gt;open</a> are
+largely the same.  There is some re-organization, and note that the
+enclosing DB_ENV structure is specified when the DB object
+is created using the <a href="../../api_c/db_create.html">db_create</a> interface.  There is one
+additional argument to <a href="../../api_c/db_open.html">DB-&gt;open</a>, argument #3.  For backward
+compatibility with the 2.X Berkeley DB releases, simply set that argument to
+NULL.
+<p>There are two additional issues with the db_open call.
+<p>First, it was possible in the 2.X releases for an application to provide
+an environment that did not contain a shared memory buffer pool as the
+database environment, and Berkeley DB would create a private one automatically.
+This functionality is no longer available, applications must specify the
+<a href="../../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a> flag if databases are going to be opened in the
+environment.
+<p>The final issue with upgrading the db_open call is that the DB_INFO
+structure is no longer used, having been replaced by individual methods
+on the DB handle.  That change is discussed in detail later in
+this chapter.

+<p>The following change applies only to applications using the

+<p>Historically, the Berkeley DB <a href="../../api_c/db_cursor.html">DB-&gt;cursor</a> interface took the DB_RMW flag
+to indicate that the created cursor would be used for write operations on
+the database.  This flag has been renamed to the <a href="../../api_c/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a>
+flag.
+<p>The application should be searched for any occurrences of DB_RMW. For
+each of these, any that are arguments to the <a href="../../api_c/db_cursor.html">DB-&gt;cursor</a> function
+should be changed to pass in the <a href="../../api_c/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a> flag instead.

+<h1 align=center>Release 3.1: identical duplicate data items</h1>
+<p>In previous releases of Berkeley DB, it was not an error to store identical
+duplicate data items, or, for those that just like the way it sounds,
+duplicate duplicates.  However, there were implementation bugs where
+storing duplicate duplicates could cause database corruption.
+<p>In this release, applications may store identical duplicate data items
+as long as the data items are unsorted.  It is an error to attempt to
+store identical duplicate data items when duplicates are being stored
+in a sorted order. This restriction is expected to be lifted in a future
+release.  See <a href="../../ref/am_conf/dup.html">Duplicate data items</a>
+for more information.

+<p>For the Queue and Recno access methods, when the <a href="../../api_c/db_put.html#DB_APPEND">DB_APPEND</a> flag
+is specified to the <a href="../../api_c/db_put.html">DB-&gt;put</a> interface, the allocated record number
+is returned to the application in the <b>key</b> <a href="../../api_c/dbt.html">DBT</a> argument.
+In previous releases of Berkeley DB, this <a href="../../api_c/dbt.html">DBT</a> structure did not follow
+the usual <a href="../../api_c/dbt.html">DBT</a> conventions, e.g., it was not possible to cause
+Berkeley DB to allocate space for the returned record number.  Rather, it was
+always assumed that the <b>data</b> field of the <b>key</b> structure
+referenced memory that could be used as storage for a db_recno_t type.
+<p>As of the Berkeley DB 3.1.0 release, the <b>key</b> structure behaves as
+described in the <a href="../../api_c/dbt.html">DBT</a> C++/Java class or C structure documentation.
+<p>Applications which are using the <a href="../../api_c/db_put.html#DB_APPEND">DB_APPEND</a> flag for Queue and
+Recno access method databases will require a change to upgrade to the
+Berkeley DB 3.1 releases.  The simplest change is likely to be to add the
+<a href="../../api_c/dbt.html#DB_DBT_USERMEM">DB_DBT_USERMEM</a> flag to the <b>key</b> structure.  For example,
+code that appears as follows:
+<p><blockquote><pre>DBT key;
+db_recno_t recno;
+<p>
+memset(&key, 0, sizeof(DBT));
+key.data = &recno;
+key.size = sizeof(recno);
+DB-&gt;put(DB, NULL, &key, &data, DB_APPEND);
+printf("new record number is %lu\n", (u_long)recno);</pre></blockquote>
+<p>would be changed to:
+<p><blockquote><pre>DBT key;
+db_recno_t recno;
+<p>
+memset(&key, 0, sizeof(DBT));
+key.data = &recno;
+key.ulen = sizeof(recno);
+key.flags = DB_DBT_USERMEM;
+DB-&gt;put(DB, NULL, &key, &data, DB_APPEND);
+printf("new record number is %lu\n", (u_long)recno);</pre></blockquote>
+<p>Note that the <b>ulen</b> field is now set as well as the flag value.
+An alternative change would be:
+<p><blockquote><pre>DBT key;
+db_recno_t recno;
+<p>
+memset(&key, 0, sizeof(DBT));
+DB-&gt;put(DB, NULL, &key, &data, DB_APPEND);
+recno = *(db_recno_t *)key-&gt;data;
+printf("new record number is %lu\n", (u_long)recno);</pre></blockquote>

+<p>On Win/32 platforms an additional test has been added when searching for
+the appropriate directory in which to create the temporary files that are
+used to back in-memory databases.  Berkeley DB now uses any return value from
+the GetTempPath interface as the temporary file directory name before
+resorting to the static list of compiled-in pathnames.
+<p>If the system registry does not return the same directory as Berkeley DB has
+been using previously, this change could cause temporary backing files to
+move to a new directory when applications are upgraded to the 3.1 release.
+In extreme cases, this could create (or fix) security problems if the file
+protection modes for the system registry directory are different from
+those on the directory previously used by Berkeley DB.

+<p>C and C++ applications that specify their own Btree key comparison,
+Btree prefix comparison, duplicate data item comparison or Hash

+required.
+<p>The app_private field of the <a href="../../api_c/dbt.html">DBT</a> structure (accessible only from

+<h1 align=center>Release 3.2: DB_INCOMPLETE</h1>
+<p>There are a number of functions that flush pages from the Berkeley DB shared
+memory buffer pool to disk.  Most of those functions can potentially
+fail because a page that needs to be flushed is not currently available.
+However, this is not a hard failure and is rarely cause for concern.
+In the Berkeley DB 3.2 release, the C++ API (if that API is configured to
+throw exceptions) and the Java API have been changed so that this
+failure does not throw an exception, but rather returns a non-zero error
+code of <a href="../../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a>.
+<p>The following C++ methods will return <a href="../../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> rather than throw
+an exception: <a href="../../api_cxx/db_close.html">Db::close</a>, <a href="../../api_cxx/db_sync.html">Db::sync</a>, <a href="../../api_cxx/memp_sync.html">DbEnv::memp_sync</a>,
+<a href="../../api_cxx/txn_checkpoint.html">DbEnv::txn_checkpoint</a>, <a href="../../api_cxx/memp_fsync.html">DbMpoolFile::sync</a>.
+<p>The following Java methods are now declared "public int" rather than
+"public void", and will return <a href="../../api_c/memp_fsync.html#DB_INCOMPLETE">Db.DB_INCOMPLETE</a> rather than
+throw an exception: <a href="../../api_java/db_close.html">Db.close</a>, <a href="../../api_java/db_sync.html">Db.sync</a>,
+<a href="../../api_java/txn_checkpoint.html">DbEnv.txn_checkpoint</a>.
+<p>It is likely that the only change required by any application will be
+those currently checking for a <a href="../../api_c/memp_fsync.html#DB_INCOMPLETE">DB_INCOMPLETE</a> return that has
+been encapsulated in an exception.

+<h1 align=center>Release 3.2: Logically renumbering records</h1>
+<p>In the Berkeley DB 3.2 release, cursor adjustment semantics changed for Recno
+databases with mutable record numbers.  Before the 3.2 release, cursors
+were adjusted to point to the previous or next record at the time the
+record referenced by the cursor was deleted.  This could lead to
+unexpected behaviors.  For example, two cursors referencing sequential
+records that were both deleted would lose their relationship to each
+other and would reference the same position in the database instead of
+their original sequential relationship.  There were also command
+sequences that would have unexpected results.  For example, DB_AFTER
+and DB_BEFORE cursor put operations, using a cursor previously used to
+delete an item, would perform the put relative to the cursor's adjusted
+position and not its original position.
+<p>In the Berkeley DB 3.2 release, cursors maintain their position in the tree
+regardless of deletion operations using the cursor.  Applications that
+perform database operations, using cursors previously used to delete
+entries in Recno databases with mutable record numbers, should be
+evaluated to ensure that the new semantics do not cause application
+failure.

+<p>A new method has been added to the Berkeley DB environment handle,
+<a href="../../api_c/env_set_flags.html">DBENV-&gt;set_flags</a>.  This interface currently takes three flags:
+<a href="../../api_c/env_set_flags.html#DB_CDB_ALLDB">DB_CDB_ALLDB</a>, <a href="../../api_c/env_open.html#DB_NOMMAP">DB_NOMMAP</a> and <a href="../../api_c/env_open.html#DB_TXN_NOSYNC">DB_TXN_NOSYNC</a>.  The
+first of these flags, <a href="../../api_c/env_set_flags.html#DB_CDB_ALLDB">DB_CDB_ALLDB</a>, provides new functionality,
+allowing Berkeley DB Concurrent Data Store applications to do locking across multiple databases.
+<p>The other two flags, <a href="../../api_c/env_open.html#DB_NOMMAP">DB_NOMMAP</a> and <a href="../../api_c/env_open.html#DB_TXN_NOSYNC">DB_TXN_NOSYNC</a>, were
+specified to the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> method in previous releases.  In
+the 3.2 release, they have been moved to the <a href="../../api_c/env_set_flags.html">DBENV-&gt;set_flags</a> function
+because this allows the database environment's value to be toggled
+during the life of the application as well as because it is a more

+<h1 align=center>Upgrading Berkeley DB installations</h1>
+<p>The following information describes the general process of upgrading
+Berkeley DB installations.  There are three issues to be considered when
+upgrading Berkeley DB applications and database environments.  They are the
+application API, the underlying database formats, and, in the case of
+transactional database environments, the log files.
+<p>An application must always be re-compiled to use a new Berkeley DB release.
+Internal Berkeley DB interfaces may change at any time and in any release,
+without warning. This means the application and library must be entirely
+recompiled and reinstalled when upgrading to new releases of the
+library, as there is no guarantee that modules from one version of the
+library will interact correctly with modules from another release.
+<p>A Berkeley DB patch release will never modify the Berkeley DB API, log file or
+database formats in non-backward compatible ways.  Berkeley DB minor and major
+releases may optionally include changes to the Berkeley DB application API,
+log files and database formats that are not backward compatible.  Note,
+that there are several underlying Berkeley DB database formats.  As all of
+them do not necessarily change at the same time, changes to one database
+format in a release may not affect any particular application.
+<p>Each Berkeley DB minor or major release has an upgrading section in this
+chapter of the Berkeley DB Reference Guide.  The section describes any API
+changes that were made in the release.  Application maintainers must
+review the API changes, update their applications as necessary, and then
+re-compile using the new release.  In addition, each section includes
+a page specifying if the log file format or database formats changed in
+non-backward compatible ways as part of the release.
+<p>If the application does not have a Berkeley DB transactional environment, the
+re-compiled application may be installed in the field using the
+following steps:
+<p><ol>
+<p><li>Shut down the old version of the application.
+<p><li>Remove any Berkeley DB environment, using the <a href="../../api_c/env_remove.html">DBENV-&gt;remove</a> function or an
+appropriate system utility.
+<p><li>Install the new version of the application.
+<p><li>If the database format has changed, upgrade the application's databases.
+See <a href="../../ref/am/upgrade.html">Upgrading databases</a> for more
+information.
+<p><li>Re-start the application.
+</ol>
+<p>If the application has a Berkeley DB transactional environment, but neither
+the log file or database formats have changed, the re-compiled
+application may be installed in the field using the following steps:
+<p><ol>
+<p><li>Shut down the old version of the application.
+<p><li>Run recovery on the database environment, using the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function
+or the <a href="../../utility/db_recover.html">db_recover</a> utility.
+<p><li>Install the new version of the application.
+<p><li>Re-start the application.
+</ol>
+<p>If the application has a Berkeley DB transactional environment, and the log
+file format has changed but the database formats have not, the
+re-compiled application may be installed in the field using the
+following steps:
+<p><ol>
+<p><li>Shut down the old version of the application.
+<p><li>Run recovery on the database environment, using the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function
+or the <a href="../../utility/db_recover.html">db_recover</a> utility.
+<p><li>Archive the database environment for catastrophic recovery.  See
+<a href="../../ref/transapp/archival.html">Archival procedures</a> for more
+information.
+<p><li>Install the new version of the application.
+<p><li>Re-start the application.
+</ol>
+<p>If the application has a Berkeley DB transactional environment and the
+database format has changed, the re-compiled application may be
+installed in the field using the following steps:
+<p><ol>
+<p><li>Shut down the old version of the application.
+<p><li>Run recovery on the database environment, using the <a href="../../api_c/env_open.html">DBENV-&gt;open</a> function
+or the <a href="../../utility/db_recover.html">db_recover</a> utility.
+<p><li>Archive the database environment for catastrophic recovery.  See
+<a href="../../ref/transapp/archival.html">Archival procedures</a> for more
+information.
+<p><li>Install the new version of the application.
+<p><li>Upgrade the application's databases.  See
+<a href="../../ref/am/upgrade.html">Upgrading databases</a> for more
+information.
+<p><li>Archive the database for catastrophic recovery again (using different
+media than before, of course).
+<p>This archival is not strictly necessary.  However, if you have to perform
+catastrophic recovery after restarting your applications, that recovery
+must be done based on the last archive you have made.  If you make this
+archive, you can use it as the basis of your catastrophic recovery.  If
+you do not make this archive, you will have to use the archive you made
+in step #2 as the basis of your recovery, and you will have to upgrade it
+as described in step #3 before you can apply your log files to it.
+<p><li>Re-start the application.

+<p>
+<h1 align=center>Configuring Berkeley DB with the Tuxedo System</h1>
+<p>This information assumes that you have already installed the Berkeley DB
+library.
+<p>First, you must update the resource manager file in Tuxedo.  For the
+purposes of this discussion, assume the Tuxedo home directory is in:
+<p><blockquote><pre>/home/tuxedo</pre></blockquote>
+In that case, the resource manager file will be located in:
+<p><blockquote><pre>/home/tuxedo/udataobj/RM</pre></blockquote>
+Edit the resource manager file, adding the following line:
+<p><blockquote><pre>BERKELEY-DB:db_xa_switch:-L${DB_INSTALL}/lib -ldb \
+	-lsocket -ldl -lm</pre></blockquote>
+<p>where ${DB_INSTALLHOME} is the directory into which you installed the Berkeley DB
+library.
+<p><b>Note, the above load options are for a Sun Microsystems Solaris
+5.6 Sparc installation of Tuxedo, and may not be correct for your system.</b>
+<p>Next, you must build the transaction manager server.  To do this, use the
+Tuxedo <b>buildtms</b>(1) utility.  The buildtms utility will create
+the Berkeley-DB resource manager in the directory from which it was run.
+The parameters to buildtms should be:
+<p><blockquote><pre>buildtms -v -o DBRM -r BERKELEY-DB</pre></blockquote>
+<p>This will create an executable transaction manager server, DBRM, that is
+called by Tuxedo to process begins, commits, and aborts.
+<p>Finally, you must make sure that your TUXCONFIG environment variable
+identifies a ubbconfig file that properly identifies your resource
+managers.  In the GROUPS section of the ubb file, you should identify the
+group's LMID and GRPNO as well as the transaction manager server name
+"TMSNAME=DBRM."  You must also specify the OPENINFO parameter, setting it
+equal to the string:
+<p><blockquote><pre>rm_name:dir</pre></blockquote>
+<p>where rm_name is the resource name specified in the RM file (i.e.,
+BERKELEY-DB) and dir is the directory for the Berkeley DB home environment
+(see <a href="../../api_c/env_open.html">DBENV-&gt;open</a> for a discussion of Berkeley DB environments).
+<p>As Tuxedo resource manager startup accepts only a single string for
+configuration, any environment customization that might have been done
+via the config parameter to <a href="../../api_c/env_open.html">DBENV-&gt;open</a> must instead be done by
+placing a <a href="../../ref/env/naming.html#DB_CONFIG">DB_CONFIG</a> file in the Berkeley DB environment directory.  See
+<a href="../../ref/env/naming.html">Berkeley DB File Naming</a> for further
+information.
+<p>Consider the following configuration.  We have built a transaction
+manager server as described above.  We want the Berkeley DB environment
+to be <b>/home/dbhome</b>, our database files to be maintained
+in <b>/home/datafiles</b>, our log files to be maintained in
+<b>/home/log</b>, and we want a duplexed server.
+<p>The GROUPS section of the ubb file might look like:
+<p><blockquote><pre>group_tm LMID=myname GRPNO=1 TMSNAME=DBRM TMSCOUNT=2 \
+	OPENINFO="BERKELEY-DB:/home/dbhome"</pre></blockquote>
+<p>There would be a <a href="../../ref/env/naming.html#DB_CONFIG">DB_CONFIG</a> configuration file in the directory
+<b>/home/dbhome</b> that contained the following two lines:
+<p><blockquote><pre>DB_DATA_DIR	/home/datafiles
+DB_LOG_DIR	/home/log
+</pre></blockquote>
+<p>Finally, the ubb file must be translated into a binary version, using
+Tuxedo's <b>tmloadcf</b>(1) utility, and then the pathname of that
+binary file must be specified as your TUXCONFIG environment variable.
+<p>At this point, your system is properly initialized to use the Berkeley DB
+resource manager.
+<p>See <a href="../../api_c/db_create.html">db_create</a> for further information on accessing data files
+using XA.

+<h1 align=center>Frequently Asked Questions</h1>
+<p><ol>
+<p><li><b>Does converting an application to run within XA change any of
+the already existing C/C++ API calls it does?</b>
+<p>When converting an application to run under XA, the application's Berkeley DB
+calls are unchanged, with two exceptions:
+<p><ol>
+<p><li>The application must use specify the <a href="../../api_c/db_create.html#DB_XA_CREATE">DB_XA_CREATE</a> flag
+to the <a href="../../api_c/db_create.html">db_create</a> interface.
+<p><li>The application should never explicitly call <a href="../../api_c/txn_commit.html">txn_commit</a>,
+<a href="../../api_c/txn_abort.html">txn_abort</a> or <a href="../../api_c/txn_begin.html">txn_begin</a>, as those calls are replaced by
+calls into the Tuxedo transaction manager.  For the same reason, the
+application will always specify a transaction argument of NULL to the
+Berkeley DB functions that take transaction arguments (e.g., <a href="../../api_c/db_put.html">DB-&gt;put</a> or
+<a href="../../api_c/db_cursor.html">DB-&gt;cursor</a>).
+</ol>
+<p>Otherwise, your application should be unchanged.
+<hr size=1 noshade>
+<p><li><b>Is it possible to mix XA and non-XA transactions?</b>
+<p>Yes.  It is also possible for XA and non-XA transactions to co-exist in
+the same Berkeley DB environment.  To do this, specify the same environment to
+the non-XA <a href="../../api_c/env_open.html">DBENV-&gt;open</a> calls as was specified in the Tuxedo
+configuration file.
+<hr size=1 noshade>
+<p><li><b>How does Berkeley DB recovery interact with recovery by the transaction
+manager?</b>
+<p>When the Tuxedo recovery calls the Berkeley DB recovery functions, the standard
+Berkeley DB recovery procedures occur, for all operations that are represented
+in the Berkeley DB log files.  This includes any non-XA transactions that were
+performed in the environment.  Of course, this means that you can't use
+the standard Berkeley DB utilities (e.g., <a href="../../utility/db_recover.html">db_recover</a>) to perform
+recovery.
+<p>Also, standard log file archival and catastrophic recovery procedures
+should occur independently of XA operation.

+<h1 align=center>Introduction</h1>
+<p>Berkeley DB can be used as an XA-compliant resource manager.  The XA
+implementation is known to work with the Tuxedo(tm) transaction
+manager.
+<p>The XA support is encapsulated in the resource manager switch
+db_xa_switch, which defines the following functions:
+<p><blockquote><pre>__db_xa_close     Close the resource manager.
+__db_xa_commit    Commit the specified transaction.
+__db_xa_complete  Wait for asynchronous operations to
+                  complete.
+__db_xa_end       Disassociate the application from a
+                  transaction.
+__db_xa_forget    Forget about a transaction that was heuristically
+                  completed. (Berkeley DB does not support heuristic
+                  completion.)
+__db_xa_open      Open the resource manager.
+__db_xa_prepare   Prepare the specified transaction.
+__db_xa_recover   Return a list of prepared, but not yet
+                  committed transactions.
+__db_xa_rollback  Abort the specified transaction.
+__db_xa_start     Associate the application with a
+                  transaction.
+</pre></blockquote>
+<p>The Berkeley DB resource manager does not support the following optional
+XA features:
+<ul type=disc>
+<li>Asynchronous operations.
+<li>Transaction migration.
+</ul>
+<p>The Tuxedo System is available from <a href="http://www.beasys.com">BEA Systems, Inc.</a>

+<h1>Description</h1>
+        <a name="3"><!--meow--></a>    
+<p>The berkeley_db_svc utility is the Berkeley DB RPC server.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt><b>-h</b><dd>Add the specified home directory to the list of allowed home directories
+that can be specified by the client.  The home directory should be an
+absolute pathname.  The last component of each home directory specified
+must be unique, as that is how clients specify which database environment
+they wish to join.
+<p>Recovery will be run on each specified environment before the server
+begins accepting requests from clients.  For this reason, only one copy
+of the server program should ever be run at any time, as recovery must
+always be single-threaded.
+<p><dt><b>-I</b><dd>Set the default idle timeout for client environments to the specified
+number of seconds.  The default timeout is 24 hours.
+<p><dt><b>-L</b><dd>Log the execution of the berkeley_db_svc utility to the specified file in the
+following format, where <i>###</i> is the process ID, and the date
+is the time the utility was started.
+<p><blockquote><pre>berkeley_db_svc: ### Wed Jun 15 01:23:45 EDT 1995</pre></blockquote>
+This file will be removed if the berkeley_db_svc utility exits gracefully.
+<p><dt><b>-t</b><dd>Set the default timeout for client resources (idle transactions and
+cursors) to the
+specified number of seconds.  When the timeout expires, if the
+resource is a transaction, it is aborted, if the resource is
+a cursor, it is closed.
+The default timeout is 5 minutes.
+<p><dt><b>-T</b><dd>Set the maximum timeout allowed for client resources.
+The default timeout is 20 minutes.
+If a client application requests a server timeout
+greater than the maximum timeout set for this server, then the client's
+timeout will be capped at the maximum timeout value.
+<p><dt><b>-V</b><dd>Write the version number to the standard output and exit.
+<p><dt><b>-v</b><dd>Run in verbose mode.
+</dl>
+<p>The berkeley_db_svc utility uses a Berkeley DB environment (as described for the
+<b>-h</b> option, the environment variable <b>DB_HOME</b>, or,
+because the utility was run in a directory containing a Berkeley DB
+environment).  In order to avoid environment corruption when using a Berkeley DB
+environment, berkeley_db_svc should always be given the chance to detach from
+the environment and exit gracefully.  To cause berkeley_db_svc to release all
+environment resources and exit cleanly, send it an interrupt signal
+(SIGINT).
+<p>The berkeley_db_svc utility exits 0 on success, and &gt;0 if an error occurs.
+<h1>Environment Variables</h1>
+<p><dl compact>
+<p><dt>DB_HOME<dd>If the <b>-h</b> option is not specified and the environment variable

+<p>The db_archive utility writes the pathnames of log files that are
+no longer in use (e.g., no longer involved in active transactions), to
+the standard output, one pathname per line.  These log files should be
+written to backup media to provide for recovery in the case of
+catastrophic failure (which also requires a snapshot of the database
+files), but they may then be deleted from the system to reclaim disk
+space.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt><b>-a</b><dd>Write all pathnames as absolute pathnames,
+instead of relative to the database home directories.
+<p><dt><b>-h</b><dd>Specify a home directory for the database environment; by
+default, the current working directory is used.
+<p><dt><b>-l</b><dd>Write out the pathnames of all of the database log files,
+whether or not they are involved in active transactions.
+<p><dt><b>-s</b><dd>Write the pathnames of all of the database files that need to be archived
+in order to recover the database from catastrophic failure.
+If any of the database files have not been accessed during the lifetime of
+the current log files, db_archive will
+not include them in this
+output.
+<p>It is possible that some of the files referenced in the log have since
+been deleted from the system.
+In this case, db_archive will ignore them.
+When <a href="../utility/db_recover.html">db_recover</a> is run, any files referenced in the log that
+are not present during recovery are assumed to have been deleted and will
+not be recovered.
+<p><dt><b>-V</b><dd>Write the version number to the standard output and exit.
+<p><dt><b>-v</b><dd>Run in verbose mode, listing the checkpoints in the log files as they
+are reviewed.

+<h1>Description</h1>
+        <a name="3"><!--meow--></a>    
+<p>The db_dump utility reads the database file <b>file</b> and
+writes it to the standard output using a portable flat-text format
+understood by the <a href="../utility/db_load.html">db_load</a> utility.  The argument <b>file</b>
+must be a file produced using the Berkeley DB library functions.
+<p>The <a href="../utility/db_dump.html">db_dump185</a> utility is similar to the db_dump utility
+except that it reads databases in the format used by Berkeley DB versions 1.85
+and 1.86.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt><b>-d</b><dd>Dump the specified database in a format helpful for debugging the Berkeley DB
+library routines.
+<p><dl compact>
+<p><dt>a<dd>Display all information.
+<dt>h<dd>Display only page headers.
+<dt>r<dd>Do not display the free-list or pages on the free list.  This
+mode is used by the recovery tests.
+</dl>
+<p><b>The output format of the <b>-d</b> option is not standard and may change,
+without notice, between releases of the Berkeley DB library.</b>
+<p><dt><b>-f</b><dd>Write to the specified <b>file</b> instead of to the standard output.
+<p><dt><b>-h</b><dd>Specify a home directory for the database environment; by
+default, the current working directory is used.
+<p><dt><b>-k</b><dd>Dump record numbers from Queue and Recno databases as keys.
+<p><dt><b>-l</b><dd>List the databases stored in the file.
+<p><dt><b>-N</b><dd>Do not acquire shared region locks while running.  Other problems such as
+potentially fatal errors in Berkeley DB will be ignored as well.  This option
+is intended only for debugging errors and should not be used under any
+other circumstances.
+<p><dt><b>-p</b><dd>If characters in either the key or data items are printing characters (as
+defined by <b>isprint</b>(3)), use printing characters in <b>file</b>
+to represent them.  This option permits users to use standard text editors
+and tools to modify the contents of databases.
+<p>Note, different systems may have different notions as to what characters
+are considered <i>printing characters</i>, and databases dumped in
+this manner may be less portable to external systems.
+<p><dt><b>-R</b><dd>Aggressively salvage data from a possibly corrupt file.  The <b>-R</b>
+flag differs from the <b>-r</b> option in that it will return all
+possible data from the file at the risk of also returning already deleted
+or otherwise nonsensical items.  Data dumped in this fashion will almost
+certainly have to be edited by hand or other means before the data is
+ready for re-load into another database
+<p><dt><b>-r</b><dd>Salvage data from a possibly corrupt file.  When used on a uncorrupted
+database, this option should return equivalent data to a normal dump, but
+most likely in a different order.
+<p><dt><b>-s</b><dd>Specify a single database to dump.  If no database is specified, all
+databases in the database file are dumped.
+<p><dt><b>-V</b><dd>Write the version number to the standard output and exit.
+</dl>
+<p>Dumping and reloading Hash databases that use user-defined hash functions
+will result in new databases that use the default hash function.
+While using the default hash function may not be optimal for the new database,
+it will continue to work correctly.
+<p>Dumping and reloading Btree databases that use user-defined prefix or
+comparison functions will result in new databases that use the default
+prefix and comparison functions.
+<b>In this case, it is quite likely that the database will be damaged
+beyond repair permitting neither record storage or retrieval.</b>
+<p>The only available workaround for either case is to modify the sources
+for the <a href="../utility/db_load.html">db_load</a> utility to load the database using the correct
+hash, prefix and comparison functions.
+<p>The <a href="../utility/db_dump.html">db_dump185</a> utility may not be available on your system as it
+is not always built when the Berkeley DB libraries and utilities are installed.
+If you are unable to find it, see your system administrator for further
+information.
+<p>The db_dump and <a href="../utility/db_dump.html">db_dump185</a> utility output formats are
+documented in the <a href="../ref/dumpload/format.html">Dump Output
+Formats</a> section of the Reference Guide.
+<p>The db_dump utility may be used with a Berkeley DB environment (as described for the
+<b>-h</b> option, the environment variable <b>DB_HOME</b>, or,
+because the utility was run in a directory containing a Berkeley DB
+environment).  In order to avoid environment corruption when using a Berkeley DB
+environment, db_dump should always be given the chance to detach from
+the environment and exit gracefully.  To cause db_dump to release all
+environment resources and exit cleanly, send it an interrupt signal
+(SIGINT).
+<p>When using an Berkeley DB database environment, the db_dump utility
+does not configure for any kind of database locking and so should not
+be used with active Berkeley DB environments.  If db_dump is used in
+an active database environment, corruption may result.
+<p>The db_dump utility exits 0 on success, and &gt;0 if an error occurs.
+<p>The <a href="../utility/db_dump.html">db_dump185</a> utility exits 0 on success, and &gt;0 if an error occurs.

+<h1>Description</h1>
+        <a name="3"><!--meow--></a>    
+<p>The db_load utility reads from the standard input and loads it
+into the database <b>file</b>.  The database <b>file</b> is created if
+it does not already exist.
+<p>The input to db_load must be in the output format specified by the
+<a href="../utility/db_dump.html">db_dump</a> utility, utilities, or as specified for the <b>-T</b>
+below.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt><b>-c</b><dd>Specify configuration options ignoring any value they may have based on
+the input.  The command-line format is <b>name=value</b>.  See
+<a href="db_load.html#Supported Keywords">Supported Keywords</a> for a
+list of supported words for the <b>-c</b> option.
+<p><dt><b>-f</b><dd>Read from the specified <b>input</b> file instead of from the standard
+input.
+<p><dt><b>-h</b><dd>Specify a home directory for the database environment.
+<p>If a home directory is specified, the database environment is opened using
+the <a href="../api_c/env_open.html#DB_INIT_LOCK">DB_INIT_LOCK</a>, <a href="../api_c/env_open.html#DB_INIT_LOG">DB_INIT_LOG</a>, <a href="../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a>,
+<a href="../api_c/env_open.html#DB_INIT_TXN">DB_INIT_TXN</a> and <a href="../api_c/env_open.html#DB_USE_ENVIRON">DB_USE_ENVIRON</a> flags to
+<a href="../api_c/env_open.html">DBENV-&gt;open</a>.  (This means that db_load can be used to load
+data into databases while they are in use by other processes.) If the
+<a href="../api_c/env_open.html">DBENV-&gt;open</a> call fails, or if no home directory is specified, the
+database is still updated, but the environment is ignored, e.g., no
+locking is done.
+<p><dt><b>-n</b><dd>Do not overwrite existing keys in the database when loading into an
+already existing database.  If a key/data pair cannot be loaded into the
+database for this reason, a warning message is displayed on the standard
+error output and the key/data pair are skipped.
+<p><dt><b>-T</b><dd>The <b>-T</b> option allows non-Berkeley DB applications to easily load text
+files into databases.
+<p>If the database to be created is of type Btree or Hash, or the keyword
+<b>keys</b> is specified as set, the input must be paired lines of text,
+where the first line of the pair is the key item, and the second line of
+the pair is its corresponding data item.  If the database to be created
+is of type Queue or Recno and the keywork <b>keys</b> is not set, the
+input must be lines of text, where each line is a new data item for the
+database.
+<p>A simple escape mechanism, where newline and backslash (\)
+characters are special, is applied to the text input.  Newline characters
+are interpreted as record separators.  Backslash characters in the text
+will be interpreted in one of two ways:  if the backslash character
+precedes another backslash character, the pair will be interpreted as a
+literal backslash.  If the backslash character precedes any other
+character, the two characters following the backslash will be interpreted
+as hexadecimal specification of a single character, e.g., \0a
+is a newline character in the ASCII character set.
+<p>For this reason, any backslash or newline characters that naturally
+occur in the text input must be escaped to avoid misinterpretation by
+db_load.
+<p>If the <b>-T</b> option is specified, the underlying access method type
+must be specified using the <b>-t</b> option.
+<p><dt><b>-t</b><dd>Specify the underlying access method.  If no <b>-t</b> option is
+specified, the database will be loaded into a database of the same type
+as was dumped, e.g., a Hash database will be created if a Hash database
+was dumped.
+<p>Btree and Hash databases may be converted from one to the other.  Queue
+and Recno databases may be converted from one to the other.  If the
+<b>-k</b> option was specified on the call to <a href="../utility/db_dump.html">db_dump</a> then Queue
+and Recno databases may be converted to Btree or Hash, with the key being
+the integer record number.
+<p><dt><b>-V</b><dd>Write the version number to the standard output and exit.
+</dl>
+<p>The db_load utility may be used with a Berkeley DB environment (as described for the
+<b>-h</b> option, the environment variable <b>DB_HOME</b>, or,
+because the utility was run in a directory containing a Berkeley DB
+environment).  In order to avoid environment corruption when using a Berkeley DB
+environment, db_load should always be given the chance to detach from
+the environment and exit gracefully.  To cause db_load to release all
+environment resources and exit cleanly, send it an interrupt signal
+(SIGINT).
+<p>The db_load utility exits 0 on success, 1 if one or more key/data
+pairs were not loaded into the database because the key already existed,
+and &gt;1 if an error occurs.
+<h3>Examples</h3>
+<p>The db_load utility can be used to load text files into databases.
+For example, the following command loads the standard UNIX
+<i>/etc/passwd</i> file into a database, with the login name as the
+key item and the entire password entry as the data item:
+<p><blockquote><pre>awk -F: '{print $1; print $0}' &lt; /etc/passwd |
+    sed 's/\\/\\\\/g' | db_load -T -t hash passwd.db</pre></blockquote>
+<p>Note that backslash characters naturally occurring in the text are escaped
+to avoid interpretation as escape characters by db_load.
+<h1>Environment Variables</h1>
+<p><dl compact>
+<p><dt>DB_HOME<dd>If the <b>-h</b> option is not specified and the environment variable
+DB_HOME is set, it is used as the path of the database home, as described
+in <a href="../api_c/env_open.html">DBENV-&gt;open</a>.
+</dl>
+<h3>Supported Keywords</h3>
+The following keywords are supported for the <b>-c</b> command-line
+option to the db_load utility.  See <a href="../api_c/db_open.html">DB-&gt;open</a> for further
+discussion of these keywords and what values should be specified.
+<p>The parenthetical listing specifies how the value part of the
+<b>name=value</b> pair is interpreted.  Items listed as (boolean) expect
+value to be <b>1</b> (set) or <b>0</b> (unset).  Items listed as
+(number) convert value to a number.  Items listed as (string) use the
+string value without modification.
+<p><dl compact>

+<p>The db_upgrade utility upgrades the Berkeley DB version of one or more
+files and the databases they contain to the current release version.
+<p>The options are as follows:
+<p><dl compact>
+<p><dt><b>-h</b><dd>Specify a home directory for the database environment; by
+default, the current working directory is used.
+<p><dt><b>-N</b><dd>Do not acquire shared region locks while running.  Other problems such as
+potentially fatal errors in Berkeley DB will be ignored as well.  This option
+is intended only for debugging errors and should not be used under any
+other circumstances.
+<p><dt><b>-s</b><dd>This flag is only meaningful when upgrading databases from releases before the
+Berkeley DB 3.1 release.
+<p>As part of the upgrade from the Berkeley DB 3.0 release to the 3.1 release, the
+on-disk format of duplicate data items changed. To correctly upgrade the
+format requires applications specify if duplicate data items in the
+database are sorted or not. Specifying the <b>-s</b> flag means that
+the duplicates are sorted, otherwise they are assumed to be unsorted.
+Incorrectly specifying the value of this flag may lead to database
+corruption.
+<p>Because the db_upgrade utility upgrades a physical file (including
+all of the databases it contains), it is not possible to use
+db_upgrade to upgrade files where some of the databases it
+includes have sorted duplicate data items and some of the databases it
+includes have unsorted duplicate data items. If the file does not have
+more than a single database, or the databases do not support duplicate
+data items, or all of the databases that support duplicate data items
+support the same style of duplicates (either sorted or unsorted),
+db_upgrade will work correctly as long as the <b>-s</b> flag is
+correctly specified. Otherwise, the file cannot be upgraded using
+db_upgrade, and must be upgraded manually using the <a href="../utility/db_dump.html">db_dump</a>
+and <a href="../utility/db_load.html">db_load</a> utilities.
+<p><dt><b>-V</b><dd>Write the version number to the standard output and exit.
+</dl>
+<p><b>It is important to realize that Berkeley DB database upgrades are done
+in place, and so are potentially destructive.</b> This means that if the
+system crashes during the upgrade procedure, or if the upgrade procedure
+runs out of disk space, the databases may be left in an inconsistent and
+unrecoverable state.  See <a href="../ref/am/upgrade.html">Upgrading
+databases</a> for more information.
+<p>The db_upgrade utility may be used with a Berkeley DB environment (as described for the
+<b>-h</b> option, the environment variable <b>DB_HOME</b>, or,
+because the utility was run in a directory containing a Berkeley DB
+environment).  In order to avoid environment corruption when using a Berkeley DB
+environment, db_upgrade should always be given the chance to detach from
+the environment and exit gracefully.  To cause db_upgrade to release all
+environment resources and exit cleanly, send it an interrupt signal
+(SIGINT).

+		Ex_tpcb sets up a framework in which to run a TPC/B test.
+		Database initialization (the -i flag) and running the
+		benchmark (-n flag) must take place separately (i.e.,
+		first create the database, then run 1 or more copies of
+		the benchmark).  Furthermore, when running more than one
+		TPCB process, it is necessary to run the deadlock detector
+		(db_deadlock), since it is possible for concurrent tpcb
+		processes to deadlock.  For performance measurement, it
+		will also be beneficial to run the db_checkpoint process
+		as well.

+ * code and or h files to process these.  (This is probably better done

+#define	_DB_CXX_H_
+//
+// C++ assumptions:
+//
+// To ensure portability to many platforms, both new and old, we make
+// few assumptions about the C++ compiler and library.  For example,
+// we do not expect STL, templates or namespaces to be available.  The
+// "newest" C++ feature used is exceptions, which are used liberally
+// to transmit error information.  Even the use of exceptions can be
+// disabled at runtime, to do so, use the DB_CXX_NO_EXCEPTIONS flags
+// with the DbEnv or Db constructor.
+//
+// C++ naming conventions:
+//
+//  - All top level class names start with Db.
+//  - All class members start with lower case letter.
+//  - All private data members are suffixed with underscore.
+//  - Use underscores to divide names into multiple words.
+//  - Simple data accessors are named with get_ or set_ prefix.
+//  - All method names are taken from names of functions in the C
+//    layer of db (usually by dropping a prefix like "db_").
+//    These methods have the same argument types and order,
+//    other than dropping the explicit arg that acts as "this".
+//
+// As a rule, each DbFoo object has exactly one underlying DB_FOO struct
+// (defined in db.h) associated with it.  In some cases, we inherit directly
+// from the DB_FOO structure to make this relationship explicit.  Often,
+// the underlying C layer allocates and deallocates these structures, so
+// there is no easy way to add any data to the DbFoo class.  When you see
+// a comment about whether data is permitted to be added, this is what
+// is going on.  Of course, if we need to add data to such C++ classes
+// in the future, we will arrange to have an indirect pointer to the
+// DB_FOO struct (as some of the classes already have).

+ * The PowerPC does a sort of pseudo-atomic locking.  You set up a
+ * 'reservation' on a chunk of memory containing a mutex by loading the
+ * mutex value with LWARX.  If the mutex has an 'unlocked' (arbitrary)
+ * value, you then try storing into it with STWCX.  If no other process or
+ * thread broke your 'reservation' by modifying the memory containing the
+ * mutex, then the STCWX succeeds; otherwise it fails and you try to get
+ * a reservation again.
+ *
+ * While mutexes are explicitly 4 bytes, a 'reservation' applies to an
+ * entire cache line, normally 32 bytes, aligned naturally.  If the mutex
+ * lives near data that gets changed a lot, there's a chance that you'll
+ * see more broken reservations than you might otherwise.  The only
+ * situation in which this might be a problem is if one processor is
+ * beating on a variable in the same cache block as the mutex while another
+ * processor tries to acquire the mutex.  That's bad news regardless
+ * because of the way it bashes caches, but if you can't guarantee that a
+ * mutex will reside in a relatively quiescent cache line, you might
+ * consider padding the mutex to force it to live in a cache line by
+ * itself.  No, you aren't guaranteed that cache lines are 32 bytes.  Some
+ * embedded processors use 16-byte cache lines, while some 64-bit
+ * processors use 128-bit cache lines.  But assuming a 32-byte cache line
+ * won't get you into trouble for now.
+ *
+ * If mutex locking is a bottleneck, then you can speed it up by adding a
+ * regular LWZ load before the LWARX load, so that you can test for the
+ * common case of a locked mutex without wasting cycles making a reservation.
+ *
+ * 'set' mutexes have the value 1, like on Intel; the returned value from
+ * MUTEX_SET() is 1 if the mutex previously had its low bit set, 0 otherwise.

+ * This file defines three types of data structures: lists, tail queues,
+ * and circular queues.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may only be traversed in the forward direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more

+/*
+ * The DB environment consists of some number of "regions", which are described
+ * by the following four structures:
+ *
+ *	REGENV	   -- shared information about the environment
+ *	REGENV_REF -- file describing system memory version of REGENV
+ *	REGION	   -- shared information about a single region
+ *	REGINFO	   -- per-process information about a REGION
+ *
+ * There are three types of memory that hold regions:
+ *	per-process heap (malloc)
+ *	file mapped into memory (mmap, MapViewOfFile)
+ *	system memory (shmget, CreateFileMapping)
+ *
+ * If the regions are private to a process, they're in malloc.  If they're
+ * public, they're in file mapped memory, or, optionally, in system memory.
+ * Regions in the filesystem are named "__db.001", "__db.002" and so on.  If
+ * we're not using a private environment allocated using malloc(3), the file
+ * "__db.001" will always exist, as we use it to synchronize on the regions,
+ * whether they exist in file mapped memory or system memory.
+ *
+ * The file "__db.001" contains a REGENV structure and a linked list of some
+ * number of REGION structures.  Each of the REGION structures describes and
+ * locks one of the underlying shared regions used by DB.
+ *
+ *	__db.001
+ *	+---------+
+ *	|REGENV  |
+ *	+---------+   +----------+
+ *	|REGION   |-> | __db.002 |
+ *	|	  |   +----------+
+ *	+---------+   +----------+
+ *	|REGION   |-> | __db.003 |
+ *	|	  |   +----------+
+ *	+---------+   +----------+
+ *	|REGION   |-> | __db.004 |
+ *	|	  |   +----------+
+ *	+---------+
+ *
+ * The only tricky part about manipulating the regions is correctly creating
+ * or joining the REGENV file, i.e., __db.001.  We have to be absolutely sure
+ * that only one process creates it, and that everyone else joins it without
+ * seeing inconsistent data.  Once that region is created, we can use normal
+ * shared locking procedures to do mutal exclusion for all other regions.
+ *
+ * One of the REGION structures in the main environment region describes the
+ * environment region itself.
+ *
+ * To lock a region, locate the REGION structure that describes it and acquire
+ * the region's mutex.  There is one exception to this rule -- the lock for the
+ * environment region itself is in the REGENV structure, and not in the REGION
+ * that describes the environment region.  That's so that we can acquire a lock
+ * without walking linked lists that could potentially change underneath us.
+ * The REGION will not be moved or removed during the life of the region, and
+ * so long-lived references to it can be held by the process.
+ *
+ * All requests to create or join a region return a REGINFO structure, which
+ * is held by the caller and used to open and subsequently close the reference
+ * to the region.  The REGINFO structure contains the per-process information
+ * that we need to access the region.
+ *
+ * The one remaining complication.  If the regions (including the environment
+ * region) live in system memory, and the system memory isn't "named" somehow
+ * in the filesystem name space, we need some way of finding it.  Do this by
+ * by writing the REGENV_REF structure into the "__db.001" file.  When we find
+ * a __db.001 file that is too small to be a real, on-disk environment, we use
+ * the information it contains to redirect to the real "__db.001" file/memory.
+ * This currently only happens when the REGENV file is in shared system memory.
+ *
+ * Although DB does not currently grow regions when they run out of memory, it
+ * would be possible to do so.  To grow a region, allocate a new region of the
+ * appropriate size, then copy the old region over it and insert the additional
+ * space into the already existing shalloc arena.  Callers may have to fix up
+ * local references, but that should be easy to do.  This failed in historic
+ * versions of DB because the region lock lived in the mapped memory, and when
+ * it was unmapped and remapped (or copied), threads could lose track of it.
+ * Once we moved that lock into a region that is never unmapped, growing should
+ * work.  That all said, current versions of DB don't implement region grow
+ * because some systems don't support mutex copying, e.g., from OSF1 V4.0:
+ *
+ *      The address of an msemaphore structure may be significant.  If the
+ *	msemaphore structure contains any value copied from an msemaphore
+ *	structure at a different address, the result is undefined.

+ * Why use a home grown package over the Tcl_Hash functions?

+ * We could have implemented the stuff below without maintaining our
+ * own list manipulation, efficiently hashing it with the available
+ * Tcl functions (Tcl_CreateHashEntry, Tcl_GetHashValue, etc).  I chose
+ * not to do so for these reasons:
+ *
+ * We still need the information below.  Using the hashing only removes
+ * us from needing the next/prev pointers.  We still need the structure
+ * itself because we need more than one value associated with a widget.
+ * We need to keep track of parent pointers for sub-widgets (like cursors)
+ * so we can correctly close.  We need to keep track of individual widget's
+ * id counters for any sub-widgets they may have.  We need to be able to
+ * associate the name/client data outside the scope of the widget.
+ *
+ * So, is it better to use the hashing rather than
+ * the linear list we have now?  I decided against it for the simple reason
+ * that to access the structure would require two calls.  The first is
+ * Tcl_FindHashEntry(table, key) and then, once we have the entry, we'd
+ * have to do Tcl_GetHashValue(entry) to get the pointer of the structure.
+ *
+ * I believe the number of simultaneous DB widgets in existence at one time
+ * is not going to be that large (more than several dozen) such that
+ * linearly searching the list is not going to impact performance in a
+ * noticable way.  Should performance be impacted due to the size of the
+ * info list, then perhaps it is time to revisit this decision.

+ * Declaration of class DB_ENV_JAVAINFO
+ *
+ * A DB_ENV_JAVAINFO is allocated and stuffed into the cj_internal
+ * and the db_errpfx for every DB_ENV created.  It holds a
+ * little extra info that is needed to support callbacks.
+ *
+ * There's a bit of trickery here, because we have built this
+ * above a layer that has a C function callback that gets
+ * invoked when an error occurs.  One of the C callback's arguments
+ * is the prefix from the DB_ENV, but since we stuffed a pointer
+ * to our own DB_ENV_JAVAINFO into the prefix, we get that object as an
+ * argument to the C callback.  Thus, the C callback can have
+ * access to much more than just the prefix, and it needs that
+ * to call back into the Java enviroment.
+ *
+ * The DB_ENV_JAVAINFO object holds a copy of the Java Virtual Machine,
+ * which is needed to attach to the current running thread
+ * whenever we need to make a callback.  (This is more reliable
+ * than our previous approach, which was to save the thread
+ * that created the DbEnv).  It also has the Java callback object,
+ * as well as a 'default' callback object that is used when the
+ * caller sets the callback to null.  It also has the original
+ * error prefix, since we overwrote the one in the DB_ENV.
+ * There are also fields that are unrelated to the handling
+ * of callbacks, but are convenient to attach to a DB_ENV.
+ *
+ * Note: We assume that the Java layer is the only one
+ * fiddling with the contents of db_errpfx, db_errcall, cj_internal
+ * for a DB_ENV that was created via Java.  Since the Java layer should
+ * have the only pointer to such a DB_ENV, this should be true.

+Synchronization in the Locking Subsystem
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+1. Data structures
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The lock manager maintains 3 different structures:
+
+Objects (__db_lockobj):
+	Describes an object that is locked.  When used with DB, this consists
+	of a __db_ilock (a file identifier and a page number).
+
+Lockers (__db_locker):
+	Identifies a specific locker ID and maintains the head of a list of
+	locks held by a locker (for using during transaction commit/abort).
+
+Locks (__db_lock):
+	Describes a particular object lock held on behalf of a particular
+	locker id.
+
+Objects and Lockers reference Locks.
+
+These structures are organized via two synchronized hash tables.  Each
+hash table consists of two physical arrays: the array of actual hash
+buckets and an array of mutexes so we can lock individual buckets, rather
+than the whole table.
+
+One hash table contains Objects and the other hash table contains Lockers.
+Objects contain two lists of locks, waiters and holders: holders currently
+hold a lock on the Object, waiters are lock waiting to be granted.
+Lockers are a single linked list that connects the Locks held on behalf
+of the specific locker ID.
+
+In the diagram below:
+
+Locker ID #1 holds a lock on Object #1 (L1) and Object #2 (L5), and is
+waiting on a lock on Object #1 (L3).
+
+Locker ID #2 holds a lock on Object #1 (L2) and is waiting on a lock for
+Object #2 (L7).
+
+Locker ID #3 is waiting for a lock on Object #2 (L6).

+2. Synchronization
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+There are four types of mutexes in the subsystem.
+
+Object mutexes;
+	These map one-to-one to each bucket in the Object hash table.
+	Holding a mutex on an Object bucket secures all the Objects in
+	that bucket as well as the Lock structures linked from those
+	Objects.  All fields in the Locks EXCEPT the Locker links (the
+	links that attach Locks by Locker ID) are protected by these
+	mutexes.
+
+Locker mutexes:
+	These map one-to-one to each bucket in the Locker hash table.
+	Holding a mutex on a Locker bucket secures the Locker structures
+	and the Locker links in the Locks.
+
+Memory mutex:
+	This mutex allows calls to allocate/free memory, i.e. calls to
+	__db_shalloc and __db_shalloc_free, as well as manipulation of
+	the Object, Locker and Lock free lists.
+
+Region mutex:
+	This mutex is currently only used to protect the locker ids.
+	It may also be needed later to provide exclusive access to
+	the region for deadlock detection.
+
+Creating or removing a Lock requires locking both the Object lock and the
+Locker lock (and eventually the shalloc lock to return the item to the
+free list).
+
+The locking hierarchy is as follows:
+
+	The Region mutex may never be acquired after any other mutex.
+
+	The Object mutex may be acquired after the Region mutex.
+
+	The Locker mutex may be acquired after the Region and Object
+	mutexes.
+
+	The Memory mutex may be acquired after any mutex.
+
+So, if both and Object mutex and a Locker mutex are going to be acquired,
+the Object mutex must be acquired first.
+
+The Memory mutex may be acquired after any other mutex, but no other mutexes
+can be acquired once the Memory mutex is held.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+3. The algorithms:
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+The locking subsystem supports four basic operations:
+	Get a Lock (lock_get)
+
+	Release a Lock (lock_put)
+
+	Release all the Locks on a specific Object (lock_vec)
+
+	Release all the Locks for a specific Locker (lock_vec)
+
+Get a lock:
+	Acquire Object bucket mutex.
+	Acquire Locker bucket mutex.
+
+	Acquire Memory mutex.
+	If the Object does not exist
+		Take an Object off the freelist.
+	If the Locker doesn't exist
+		Take a Locker off the freelist.
+	Take a Lock off the free list.
+	Release Memory mutex.
+
+	Add Lock to the Object list.
+	Add Lock to the Locker list.
+	Release Locker bucket mutex
+
+	If the lock cannot be granted
+		Release Object bucket mutex
+		Acquire lock mutex (blocks)
+
+		Acquire Object bucket mutex
+		If lock acquisition did not succeed (e.g, deadlock)
+			Acquire Locker bucket mutex
+			If locker should be destroyed
+				Remove locker from hash table
+				Acquire Memory mutex
+				Return locker to free list
+				Release Memory mutex
+			Release Locker bucket mutex
+
+			If object should be released
+				Acquire Memory mutex
+				Return object to free list
+				Release Memory mutex
+
+	Release Object bucket mutex
+
+Release a lock:
+	Acquire Object bucket mutex.
+		(Requires that we be able to find the Object hash bucket
+		without looking inside the Lock itself.)
+
+	If releasing a single lock and the user provided generation number
+	doesn't match the Lock's generation number, the Lock has been reused
+	and we return failure.
+
+	Enter lock_put_internal:
+		if the Lock is still on the Object's lists:
+			Increment Lock's generation number.
+			Remove Lock from the Object's list (NULL link fields).
+			Promote locks for the Object.
+
+		Enter locker_list_removal
+			Acquire Locker bucket mutex.
+			If Locker doesn't exist:
+				Release Locker bucket mutex
+				Release Object bucket mutex
+				Return error.
+			Else if Locker marked as deleted:
+				dont_release = TRUE
+			Else
+				Remove Lock from Locker list.
+				If Locker has no more locks
+					Remove Locker from table.
+					Acquire Memory mutex.
+					Return Locker to free list
+					Release Memory mutex
+			Release Locker bucket mutex.
+		Exit locker_list_removal
+
+		If (!dont_release)
+			Acquire Memory mutex
+			Return Lock to free list
+			Release Memory mutex
+
+	Exit lock_put_internal
+
+	Release Object bucket mutex
+
+Release all the Locks on a specific Object (lock_vec, DB_PUT_ALL_OBJ):
+
+	Acquire Object bucket mutex.
+
+	For each lock on the waiter list:
+		lock_put_internal
+	For each lock on the holder list:
+		lock_put_internal
+
+	Release Object bucket mutex.
+
+Release all the Locks for a specific Locker (lock_vec, DB_PUT_ALL):
+
+	Acquire Locker bucket mutex.
+	Mark Locker deleted.
+	Release Locker mutex.
+
+	For each lock on the Locker's list:
+		Remove from locker's list
+			(The lock could get put back on the free list in
+			lock_put and then could get reallocated and the
+			act of setting its locker links could clobber us.)
+		Perform "Release a Lock" above: skip locker_list_removal.
+
+	Acquire Locker bucket mutex.
+	Remove Locker
+	Release Locker mutex.
+
+	Acquire Memory mutex
+	Return Locker to free list
+	Release Memory mutex
+
+Deadlock detection (lock_detect):
+
+	For each bucket in Object table
+		Acquire the Object bucket mutex.
+		create waitsfor
+
+	For each bucket in Object table
+		Release the Object mutex.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+FAQ:
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+Q: Why do you need generation numbers?
+A: If a lock has been released due to a transaction abort (potentially in a
+   different process), and then lock is released by a thread of control
+   unaware of the abort, the lock might have potentially been re-allocated
+   to a different object.  The generation numbers detect this problem.
+
+   Note, we assume that reads/writes of lock generation numbers are atomic,
+   if they are not, it is theoretically possible that a re-allocated lock
+   could be mistaken for another lock.
+
+Q: Why is is safe to walk the Locker list without holding any mutexes at
+   all?
+A: Locks are created with both the Object and Locker bucket mutexes held.
+   Once created, they removed in two ways:
+
+   a) when a specific Lock is released, in which case, the Object and
+   Locker bucket mutexes are again held, and
+
+   b) when all Locks for a specific Locker Id is released.
+
+   In case b), the Locker bucket mutex is held while the Locker chain is
+   marked as "destroyed", which blocks any further access to the Locker
+   chain.  Then, each individual Object bucket mutex is acquired when each
+   individual Lock is removed.
+
+Q: What are the implications of doing fine grain locking?
+
+A: Since we no longer globally lock the entire region, lock_vec will no
+   longer be atomic.  We still execute the items in a lock_vec in order,
+   so things like lock-coupling still work, but you can't make any
+   guarantees about atomicity.
+
+Q: How do I configure for FINE_GRAIN locking?
+
+A: We currently do not support any automatic configuration for FINE_GRAIN
+   locking.  When we do, will need to document that atomicity discussion
+   listed above (it is bug-report #553).

+ * open files.  This is the point from which recovery can start and the
+ * point up to which archival/truncation can take place.  Checkpoints in

+ *
+ * If we read what log returns from using the DB_CKP parameter to logput,
+ * we'll get the record at LSN 1000.  The checkpoint LSN there is 600.
+ * Now we have to scan backwards looking for a checkpoint before LSN 600.
+ * We find one at 500.  This means that we can truncate the log before
+ * 500 or run recovery beginning at 500.

+ * Returns 0 if we find a suitable checkpoint or we retrieved the first
+ * record in the log from which to start.  Returns DB_NOTFOUND if there

+
+There are three ways we do locking in the mpool code:
+
+Locking a handle mutex to provide concurrency for DB_THREAD operations.
+Locking the region mutex to provide mutual exclusion while reading and
+    writing structures in the shared region.
+Locking buffer header mutexes during I/O.
+
+The first will not be further described here.  We use the shared mpool
+region lock to provide mutual exclusion while reading/modifying all of
+the data structures, including the buffer headers.  We use a per-buffer
+header lock to wait on buffer I/O.  The order of locking is as follows:
+
+Searching for a buffer:
+    Acquire the region lock.
+    Find the buffer header.
+    Increment the reference count (guarantee the buffer stays).
+    While the BH_LOCKED flag is set (I/O is going on) {
+	Release the region lock.
+	    Explicitly yield the processor if it's not the first pass
+	    through this loop, otherwise, we can simply spin because
+	    we'll be simply switching between the two locks.
+	Request the buffer lock.
+	The I/O will complete...
+	Acquire the buffer lock.
+	Release the buffer lock.
+	Acquire the region lock.
+    }
+    Return the buffer.
+
+Reading/writing a buffer:
+    Acquire the region lock.
+    Find/create the buffer header.
+    If reading, increment the reference count (guarantee the buffer stays).
+    Set the BH_LOCKED flag.
+    Acquire the buffer lock (guaranteed not to block).
+    Release the region lock.
+    Do the I/O and/or initialize the buffer contents.
+    Release the buffer lock.
+	At this point, the buffer lock is available, but the logical
+	operation (flagged by BH_LOCKED) is not yet completed.  For
+	this reason, among others, threads checking the BH_LOCKED flag
+	must loop around their test.
+    Acquire the region lock.
+    Clear the BH_LOCKED flag.
+    Release the region lock.
+    Return/discard the buffer.
+
+Pointers to DB_MPOOL, MPOOL, DB_MPOOLFILE and MPOOLFILE structures are
+not reacquired when a region lock is reacquired because they couldn't
+have been closed/discarded and because they never move in memory.

+
+Note: this only applies to locking using test-and-set and fcntl calls,
+pthreads were added after this was written.
+
+Resource locking routines: lock based on a db_mutex_t.  All this gunk
+(including trying to make assembly code portable), is necessary because
+System V semaphores require system calls for uncontested locks and we
+don't want to make two system calls per resource lock.
+
+First, this is how it works.  The db_mutex_t structure contains a resource
+test-and-set lock (tsl), a file offset, a pid for debugging and statistics
+information.
+
+If HAVE_MUTEX_THREADS is defined (i.e. we know how to do test-and-sets
+for this compiler/architecture combination), we try and lock the resource
+tsl __os_spin() times.  If we can't acquire the lock that way, we use a
+system call to sleep for 1ms, 2ms, 4ms, etc.  (The time is bounded at 1
+second, just in case.)  Using the timer backoff means that there are two
+assumptions: that locks are held for brief periods (never over system
+calls or I/O) and that locks are not hotly contested.
+
+If HAVE_MUTEX_THREADS is not defined, i.e. we can't do test-and-sets, we
+use a file descriptor to do byte locking on a file at a specified offset.
+In this case, ALL of the locking is done in the kernel.  Because file
+descriptors are allocated per process, we have to provide the file
+descriptor as part of the lock call.  We still have to do timer backoff
+because we need to be able to block ourselves, i.e. the lock manager
+causes processes to wait by having the process acquire a mutex and then
+attempting to re-acquire the mutex.  There's no way to use kernel locking
+to block yourself, i.e. if you hold a lock and attempt to re-acquire it,
+the attempt will succeed.
+
+Next, let's talk about why it doesn't work the way a reasonable person
+would think it should work.
+
+Ideally, we'd have the ability to try to lock the resource tsl, and if
+that fails, increment a counter of waiting processes, then block in the
+kernel until the tsl is released.  The process holding the resource tsl
+would see the wait counter when it went to release the resource tsl, and
+would wake any waiting processes up after releasing the lock.  This would
+actually require both another tsl (call it the mutex tsl) and
+synchronization between the call that blocks in the kernel and the actual
+resource tsl.  The mutex tsl would be used to protect accesses to the
+db_mutex_t itself.  Locking the mutex tsl would be done by a busy loop,
+which is safe because processes would never block holding that tsl (all
+they would do is try to obtain the resource tsl and set/check the wait
+count).  The problem in this model is that the blocking call into the
+kernel requires a blocking semaphore, i.e. one whose normal state is
+locked.
+
+The only portable forms of locking under UNIX are fcntl(2) on a file
+descriptor/offset, and System V semaphores.  Neither of these locking
+methods are sufficient to solve the problem.
+
+The problem with fcntl locking is that only the process that obtained the
+lock can release it.  Remember, we want the normal state of the kernel
+semaphore to be locked.  So, if the creator of the db_mutex_t were to
+initialize the lock to "locked", then a second process locks the resource
+tsl, and then a third process needs to block, waiting for the resource
+tsl, when the second process wants to wake up the third process, it can't
+because it's not the holder of the lock!  For the second process to be
+the holder of the lock, we would have to make a system call per
+uncontested lock, which is what we were trying to get away from in the
+first place.
+
+There are some hybrid schemes, such as signaling the holder of the lock,
+or using a different blocking offset depending on which process is
+holding the lock, but it gets complicated fairly quickly.  I'm open to
+suggestions, but I'm not holding my breath.
+
+Regardless, we use this form of locking when HAVE_SPINLOCKS is not
+defined, (i.e. we're locking in the kernel) because it doesn't have the
+limitations found in System V semaphores, and because the normal state of
+the kernel object in that case is unlocked, so the process releasing the
+lock is also the holder of the lock.
+
+The System V semaphore design has a number of other limitations that make
+it inappropriate for this task.  Namely:
+
+First, the semaphore key name space is separate from the file system name
+space (although there exist methods for using file names to create
+semaphore keys).  If we use a well-known key, there's no reason to believe
+that any particular key will not already be in use, either by another
+instance of the DB application or some other application, in which case
+the DB application will fail.  If we create a key, then we have to use a
+file system name to rendezvous and pass around the key.
+
+Second, System V semaphores traditionally have compile-time, system-wide
+limits on the number of semaphore keys that you can have.  Typically, that
+number is far too low for any practical purpose.  Since the semaphores
+permit more than a single slot per semaphore key, we could try and get
+around that limit by using multiple slots, but that means that the file
+that we're using for rendezvous is going to have to contain slot
+information as well as semaphore key information, and we're going to be
+reading/writing it on every db_mutex_t init or destroy operation.  Anyhow,
+similar compile-time, system-wide limits on the numbers of slots per
+semaphore key kick in, and you're right back where you started.
+
+My fantasy is that once POSIX.1 standard mutexes are in wide-spread use,
+we can switch to them.  My guess is that it won't happen, because the
+POSIX semaphores are only required to work for threads within a process,
+and not independent processes.
+
+Note: there are races in the statistics code, but since it's just that,
+I didn't bother fixing them.  (The fix requires a mutex tsl, so, when/if
+this code is fixed to do rational locking (see above), then change the
+statistics update code to acquire/release the mutex tsl.

+=head1 DESCRIPTION
+
+B<NOTE: This document is still under construction. Expect it to be
+incomplete in places.>
+
+This Perl module provides an interface to most of the functionality
+available in Berkeley DB versions 2 and 3. In general it is safe to assume
+that the interface provided here to be identical to the Berkeley DB
+interface. The main changes have been to make the Berkeley DB API work
+in a Perl way. Note that if you are using Berkeley DB 2.x, the new
+features available in Berkeley DB 3.x are not available via this module.
+
+The reader is expected to be familiar with the Berkeley DB
+documentation. Where the interface provided here is identical to the
+Berkeley DB library and the... TODO
+
+The B<db_appinit>, B<db_cursor>, B<db_open> and B<db_txn> man pages are
+particularly relevant.
+
+The interface to Berkeley DB is implemented with a number of Perl
+classes.
+
+=head1 ENV CLASS
+
+The B<BerkeleyDB::Env> class provides an interface to the Berkeley DB
+function B<db_appinit> in Berkeley DB 2.x or B<db_env_create> and
+B<DBENV-E<gt>open> in Berkeley DB 3.x. Its purpose is to initialise a
+number of sub-systems that can then be used in a consistent way in all
+the databases you make use of the environment.
+
+If you don't intend using transactions, locking or logging, then you
+shouldn't need to make use of B<BerkeleyDB::Env>.
+
+=head2 Synopsis
+
+    $env = new BerkeleyDB::Env
+             [ -Home         => $path, ]
+             [ -Server       => $name, ]
+             [ -CacheSize    => $number, ]
+             [ -Config       => { name => value, name => value }, ]
+             [ -ErrFile      => filename or filehandle, ]
+             [ -ErrPrefix    => "string", ]
+             [ -Flags        => number, ]
+             [ -LockDetect   => number, ]
+             [ -Verbose      => boolean, ]
+
+=over 5
+
+All the parameters to the BerkeleyDB::Env constructor are optional.
+
+=item -Home
+
+If present, this parameter should point to an existing directory. Any
+files that I<aren't> specified with an absolute path in the sub-systems
+that are initialised by the BerkeleyDB::Env class will be assumed to
+live in the B<Home> directory.
+
+For example, in the code fragment below the database "fred.db" will be
+opened in the directory "/home/databases" because it was specified as a
+relative path, but "joe.db" will be opened in "/other" because it was
+part of an absolute path.
+
+    $env = new BerkeleyDB::Env
+             -Home         => "/home/databases"
+    ...
+
+    $db1 = new BerkeleyDB::Hash
+	     -Filename = "fred.db",
+	     -Env => $env
+    ...
+
+    $db2 = new BerkeleyDB::Hash
+	     -Filename = "/other/joe.db",
+	     -Env => $env
+    ...
+
+=item -Server
+
+If present, this parameter should be the hostname of a server that is running
+the Berkeley DB RPC server. All databases will be accessed via the RPC server.
+
+=item -Cachesize
+
+If present, this parameter sets the size of the environments shared memory
+buffer pool.
+
+=item -Config
+
+This is a variation on the C<-Home> parameter, but it allows finer
+control of where specific types of files will be stored.
+
+The parameter expects a reference to a hash. Valid keys are:
+B<DB_DATA_DIR>, B<DB_LOG_DIR> and B<DB_TMP_DIR>
+
+The code below shows an example of how it can be used.
+
+    $env = new BerkeleyDB::Env
+             -Config => { DB_DATA_DIR => "/home/databases",
+                          DB_LOG_DIR  => "/home/logs",
+                          DB_TMP_DIR  => "/home/tmp"
+                        }
+    ...
+
+=item -ErrFile
+
+Expects either the name of a file or a reference to a filehandle. Any
+errors generated internally by Berkeley DB will be logged to this file.
+
+=item -ErrPrefix
+
+Allows a prefix to be added to the error messages before they are sent
+to B<-ErrFile>.
+
+=item -Flags
+
+The B<Flags> parameter specifies both which sub-systems to initialise,
+as well as a number of environment-wide options.
+See the Berkeley DB documentation for more details of these options.
+
+Any of the following can be specified by OR'ing them:
+
+B<DB_CREATE>
+
+If any of the files specified do not already exist, create them.
+
+B<DB_INIT_CDB>
+
+Initialise the Concurrent Access Methods  
+
+B<DB_INIT_LOCK>
+
+Initialise the Locking sub-system.
+
+B<DB_INIT_LOG>
+
+Initialise the Logging sub-system.

+
+Initialise the ...

+
+B<DB_TXN_NOSYNC>
+
+B<DB_USE_ENVIRON>
+
+B<DB_USE_ENVIRON_ROOT>
+
+=item -LockDetect
+
+Specifies what to do when a lock conflict occurs. The value should be one of
+
+B<DB_LOCK_DEFAULT> 
+
+B<DB_LOCK_OLDEST>
+
+B<DB_LOCK_RANDOM>
+
+B<DB_LOCK_YOUNGEST>
+
+=item -Verbose
+
+Add extra debugging information to the messages sent to B<-ErrFile>.

+
+=head2 Methods
+
+The environment class has the following methods:
+
+=over 5
+
+=item $env->errPrefix("string") ;
+
+This method is identical to the B<-ErrPrefix> flag. It allows the
+error prefix string to be changed dynamically.
+
+=item $txn = $env->TxnMgr()
+
+Constructor for creating a B<TxnMgr> object.
+See L<"TRANSACTIONS"> for more details of using transactions.
+
+This method is deprecated. Access the transaction methods using the B<txn_>
+methods below from the environment object directly.

+TODO
+
+=item $env->txn_stat()

+
+=item $env->txn_checkpoint()
+
+TODO
+
+=item $env->status()
+
+Returns the status of the last BerkeleyDB::Env method.
+
+=item $env->setmutexlocks()
+
+Only available in Berkeley Db 3.0 or greater. Calls 
+B<db_env_set_mutexlocks> when used with Berkeley DB 3.1.x. When used with
+Berkeley DB 3.0 or 3.2 and better it calls B<DBENV-E<gt>set_mutexlocks>.

+=head2 Examples
+
+TODO.
+
+=head1 THE DATABASE CLASSES
+
+B<BerkeleyDB> supports the following database formats:
+
+=over 5
+
+=item B<BerkeleyDB::Hash>
+
+This database type allows arbitrary key/value pairs to be stored in data
+files. This is equivalent to the functionality provided by other
+hashing packages like DBM, NDBM, ODBM, GDBM, and SDBM. Remember though,
+the files created using B<BerkeleyDB::Hash> are not compatible with any
+of the other packages mentioned.
+
+A default hashing algorithm, which will be adequate for most applications,
+is built into BerkeleyDB. If you do need to use your own hashing algorithm
+it is possible to write your own in Perl and have B<BerkeleyDB> use
+it instead.
+
+=item B<BerkeleyDB::Btree>
+
+The Btree format allows arbitrary key/value pairs to be stored in a
+B+tree.
+
+As with the B<BerkeleyDB::Hash> format, it is possible to provide a
+user defined Perl routine to perform the comparison of keys. By default,
+though, the keys are stored in lexical order.
+
+=item B<BerkeleyDB::Recno>
+
+TODO.
+
+
+=item B<BerkeleyDB::Queue>
+
+TODO.
+
+=item B<BerkeleyDB::Unknown>
+
+This isn't a database format at all. It is used when you want to open an
+existing Berkeley DB database without having to know what type is it. 
+
+=back
+
+
+Each of the database formats described above is accessed via a
+corresponding B<BerkeleyDB> class. These will be described in turn in
+the next sections.
+
+=head1 BerkeleyDB::Hash
+
+Equivalent to calling B<db_open> with type B<DB_HASH> in Berkeley DB 2.x and
+calling B<db_create> followed by B<DB-E<gt>open> with type B<DB_HASH> in
+Berkeley DB 3.x. 
+
+Two forms of constructor are supported:
+
+    $db = new BerkeleyDB::Hash
+                [ -Filename      => "filename", ]
+                [ -Subname       => "sub-database name", ]
+                [ -Flags         => flags,]
+                [ -Property      => flags,]
+                [ -Mode          => number,]
+                [ -Cachesize     => number,]
+                [ -Lorder        => number,]
+                [ -Pagesize      => number,]
+                [ -Env           => $env,]
+                [ -Txn           => $txn,]
+                # BerkeleyDB::Hash specific
+                [ -Ffactor       => number,]
+                [ -Nelem         => number,]
+                [ -Hash          => code reference,]
+                [ -DupCompare    => code reference,]
+
+and this
+
+    [$db =] tie %hash, 'BerkeleyDB::Hash', 
+                [ -Filename      => "filename", ]
+                [ -Subname       => "sub-database name", ]
+                [ -Flags         => flags,]
+                [ -Property      => flags,]
+                [ -Mode          => number,]
+                [ -Cachesize     => number,]
+                [ -Lorder        => number,]
+                [ -Pagesize      => number,]
+                [ -Env           => $env,]
+                [ -Txn           => $txn,]
+                # BerkeleyDB::Hash specific
+                [ -Ffactor       => number,]
+                [ -Nelem         => number,]
+                [ -Hash          => code reference,]
+                [ -DupCompare    => code reference,]
+
+
+When the "tie" interface is used, reading from and writing to the database
+is achieved via the tied hash. In this case the database operates like
+a Perl associative array that happens to be stored on disk.
+
+In addition to the high-level tied hash interface, it is possible to
+make use of the underlying methods provided by Berkeley DB
+
+=head2 Options
+
+In addition to the standard set of options (see L<COMMON OPTIONS>)
+B<BerkeleyDB::Hash> supports these options:
+
+=over 5
+
+=item -Property
+
+Used to specify extra flags when opening a database. The following
+flags may be specified by logically OR'ing together one or more of the
+following values:
+
+B<DB_DUP>
+
+When creating a new database, this flag enables the storing of duplicate
+keys in the database. If B<DB_DUPSORT> is not specified as well, the
+duplicates are stored in the order they are created in the database.
+
+B<DB_DUPSORT>
+
+Enables the sorting of duplicate keys in the database. Ignored if
+B<DB_DUP> isn't also specified.
+
+=item -Ffactor
+
+=item -Nelem
+
+See the Berkeley DB documentation for details of these options.
+
+=item -Hash
+
+Allows you to provide a user defined hash function. If not specified, 
+a default hash function is used. Here is a template for a user-defined
+hash function
+
+    sub hash
+    {
+        my ($data) = shift ;
+        ...
+        # return the hash value for $data
+	return $hash ;
+    }
+
+    tie %h, "BerkeleyDB::Hash", 
+        -Filename => $filename, 
+    	-Hash     => \&hash,
+	...
+
+See L<""> for an example.
+
+=item -DupCompare
+
+Used in conjunction with the B<DB_DUPOSRT> flag. 
+
+    sub compare
+    {
+	my ($key, $key2) = @_ ;
+        ...
+        # return  0 if $key1 eq $key2
+        #        -1 if $key1 lt $key2
+        #         1 if $key1 gt $key2
+        return (-1 , 0 or 1) ;
+    }
+
+    tie %h, "BerkeleyDB::Hash", 
+        -Filename   => $filename, 
+	-Property   => DB_DUP|DB_DUPSORT,
+    	-DupCompare => \&compare,
+	...
+
+=back
+
+
+=head2 Methods
+
+B<BerkeleyDB::Hash> only supports the standard database methods.
+See L<COMMON DATABASE METHODS>.
+
+=head2 A Simple Tied Hash Example
+
+    use strict ;
+    use BerkeleyDB ;
+    use vars qw( %h $k $v ) ;
+
+    my $filename = "fruit" ;
+    unlink $filename ;
+    tie %h, "BerkeleyDB::Hash",
+                -Filename => $filename,
+		-Flags    => DB_CREATE
+        or die "Cannot open file $filename: $! $BerkeleyDB::Error\n" ;
+
+    # Add a few key/value pairs to the file
+    $h{"apple"} = "red" ;
+    $h{"orange"} = "orange" ;
+    $h{"banana"} = "yellow" ;
+    $h{"tomato"} = "red" ;
+
+    # Check for existence of a key
+    print "Banana Exists\n\n" if $h{"banana"} ;
+
+    # Delete a key/value pair.
+    delete $h{"apple"} ;
+
+    # print the contents of the file
+    while (($k, $v) = each %h)
+      { print "$k -> $v\n" }
+
+    untie %h ;
+
+here is the output:
+
+    Banana Exists
+    
+    orange -> orange
+    tomato -> red
+    banana -> yellow
+
+Note that the like ordinary associative arrays, the order of the keys
+retrieved from a Hash database are in an apparently random order.
+
+=head2 Another Simple Hash Example
+
+Do the same as the previous example but not using tie.
+
+    use strict ;
+    use BerkeleyDB ;
+
+    my $filename = "fruit" ;
+    unlink $filename ;
+    my $db = new BerkeleyDB::Hash
+                -Filename => $filename,
+		-Flags    => DB_CREATE
+        or die "Cannot open file $filename: $! $BerkeleyDB::Error\n" ;
+
+    # Add a few key/value pairs to the file
+    $db->db_put("apple", "red") ;
+    $db->db_put("orange", "orange") ;
+    $db->db_put("banana", "yellow") ;
+    $db->db_put("tomato", "red") ;
+
+    # Check for existence of a key
+    print "Banana Exists\n\n" if $db->db_get("banana", $v) == 0;
+
+    # Delete a key/value pair.
+    $db->db_del("apple") ;
+
+    # print the contents of the file
+    my ($k, $v) = ("", "") ;
+    my $cursor = $db->db_cursor() ;
+    while ($cursor->c_get($k, $v, DB_NEXT) == 0)
+      { print "$k -> $v\n" }
+
+    undef $cursor ;
+    undef $db ;
+
+=head2 Duplicate keys
+
+The code below is a variation on the examples above. This time the hash has
+been inverted. The key this time is colour and the value is the fruit name.
+The B<DB_DUP> flag has been specified to allow duplicates.
+
+    use strict ;
+    use BerkeleyDB ;
+
+    my $filename = "fruit" ;
+    unlink $filename ;
+    my $db = new BerkeleyDB::Hash
+                -Filename => $filename,
+		-Flags    => DB_CREATE,
+		-Property  => DB_DUP
+        or die "Cannot open file $filename: $! $BerkeleyDB::Error\n" ;
+
+    # Add a few key/value pairs to the file
+    $db->db_put("red", "apple") ;
+    $db->db_put("orange", "orange") ;
+    $db->db_put("green", "banana") ;
+    $db->db_put("yellow", "banana") ;
+    $db->db_put("red", "tomato") ;
+    $db->db_put("green", "apple") ;
+
+    # print the contents of the file
+    my ($k, $v) = ("", "") ;
+    my $cursor = $db->db_cursor() ;
+    while ($cursor->c_get($k, $v, DB_NEXT) == 0)
+      { print "$k -> $v\n" }
+
+    undef $cursor ;
+    undef $db ;
+
+here is the output:
+
+    orange -> orange
+    yellow -> banana
+    red -> apple
+    red -> tomato
+    green -> banana
+    green -> apple
+
+=head2 Sorting Duplicate Keys
+
+In the previous example, when there were duplicate keys, the values are
+sorted in the order they are stored in. The code below is
+identical to the previous example except the B<DB_DUPSORT> flag is
+specified.
+
+    use strict ;
+    use BerkeleyDB ;
+
+    my $filename = "fruit" ;
+    unlink $filename ;
+    my $db = new BerkeleyDB::Hash
+                -Filename => $filename,
+		-Flags    => DB_CREATE,
+		-Property  => DB_DUP | DB_DUPSORT
+        or die "Cannot open file $filename: $! $BerkeleyDB::Error\n" ;
+
+    # Add a few key/value pairs to the file
+    $db->db_put("red", "apple") ;
+    $db->db_put("orange", "orange") ;
+    $db->db_put("green", "banana") ;
+    $db->db_put("yellow", "banana") ;
+    $db->db_put("red", "tomato") ;
+    $db->db_put("green", "apple") ;
+
+    # print the contents of the file
+    my ($k, $v) = ("", "") ;
+    my $cursor = $db->db_cursor() ;
+    while ($cursor->c_get($k, $v, DB_NEXT) == 0)
+      { print "$k -> $v\n" }
+
+    undef $cursor ;
+    undef $db ;
+
+Notice that in the output below the duplicate values are sorted.

+There are a few point to bear in mind if you want to change the
+ordering in a BTREE database:
+
+=over 5
+
+=item 1.
+
+The new compare function must be specified when you create the database.

+=item 2.

+Set the cursor to point to the first key/value pair in the
+database. Return the key/value pair in C<$key> and C<$value>.

+=item B<DB_LAST>
+
+Set the cursor to point to the last key/value pair in the database. Return
+the key/value pair in C<$key> and C<$value>.
+
+=item B<DB_NEXT>
+
+If the cursor is already pointing to a key/value pair, it will be
+incremented to point to the next key/value pair and return its contents.
+
+If the cursor isn't initialised, B<DB_NEXT> works just like B<DB_FIRST>.
+
+If the cursor is already positioned at the last key/value pair, B<c_get>
+will return B<DB_NOTFOUND>.

+the next key/value pair is identical, the cursor will be incremented to
+point to it and their contents returned.

+
+=head1 DBM Filters
+
+A DBM Filter is a piece of code that is be used when you I<always>
+want to make the same transformation to all keys and/or values in a DBM
+database. All of the database classes (BerkeleyDB::Hash,
+BerkeleyDB::Btree and BerkeleyDB::Recno) support DBM Filters.
+
+There are four methods associated with DBM Filters. All work
+identically, and each is used to install (or uninstall) a single DBM
+Filter. Each expects a single parameter, namely a reference to a sub.
+The only difference between them is the place that the filter is
+installed.
+
+To summarise:
+
+=over 5
+
+=item B<filter_store_key>
+
+If a filter has been installed with this method, it will be invoked
+every time you write a key to a DBM database.
+
+=item B<filter_store_value>
+
+If a filter has been installed with this method, it will be invoked
+every time you write a value to a DBM database.
+
+
+=item B<filter_fetch_key>
+
+If a filter has been installed with this method, it will be invoked
+every time you read a key from a DBM database.
+
+=item B<filter_fetch_value>
+
+If a filter has been installed with this method, it will be invoked
+every time you read a value from a DBM database.
+
+=back
+
+You can use any combination of the methods, from none, to all four.
+
+All filter methods return the existing filter, if present, or C<undef>
+in not.
+
+To delete a filter pass C<undef> to it.
+
+=head2 The Filter
+
+When each filter is called by Perl, a local copy of C<$_> will contain
+the key or value to be filtered. Filtering is achieved by modifying
+the contents of C<$_>. The return code from the filter is ignored.
+
+=head2 An Example -- the NULL termination problem.
+
+Consider the following scenario. You have a DBM database that you need
+to share with a third-party C application. The C application assumes
+that I<all> keys and values are NULL terminated. Unfortunately when
+Perl writes to DBM databases it doesn't use NULL termination, so your
+Perl application will have to manage NULL termination itself. When you
+write to the database you will have to use something like this:
+
+    $hash{"$key\0"} = "$value\0" ;
+
+Similarly the NULL needs to be taken into account when you are considering
+the length of existing keys/values.
+
+It would be much better if you could ignore the NULL terminations issue
+in the main application code and have a mechanism that automatically
+added the terminating NULL to all keys and values whenever you write to
+the database and have them removed when you read from the database. As I'm
+sure you have already guessed, this is a problem that DBM Filters can
+fix very easily.
+
+    use strict ;
+    use BerkeleyDB ;
+
+    my %hash ;
+    my $filename = "filt.db" ;
+    unlink $filename ;
+
+    my $db = tie %hash, 'BerkeleyDB::Hash',
+    		-Filename   => $filename,
+	        -Flags      => DB_CREATE
+      or die "Cannot open $filename: $!\n" ;
+
+    # Install DBM Filters
+    $db->filter_fetch_key  ( sub { s/\0$//    } ) ;
+    $db->filter_store_key  ( sub { $_ .= "\0" } ) ;
+    $db->filter_fetch_value( sub { s/\0$//    } ) ;
+    $db->filter_store_value( sub { $_ .= "\0" } ) ;
+
+    $hash{"abc"} = "def" ;
+    my $a = $hash{"ABC"} ;
+    # ...
+    undef $db ;
+    untie %hash ;
+
+Hopefully the contents of each of the filters should be
+self-explanatory. Both "fetch" filters remove the terminating NULL,
+and both "store" filters add a terminating NULL.
+
+
+=head2 Another Example -- Key is a C int.
+
+Here is another real-life example. By default, whenever Perl writes to
+a DBM database it always writes the key and value as strings. So when
+you use this:
+
+    $hash{12345} = "something" ;
+
+the key 12345 will get stored in the DBM database as the 5 byte string
+"12345". If you actually want the key to be stored in the DBM database
+as a C int, you will have to use C<pack> when writing, and C<unpack>
+when reading.
+
+Here is a DBM Filter that does it:
+
+    use strict ;
+    use BerkeleyDB ;
+    my %hash ;
+    my $filename = "filt.db" ;
+    unlink $filename ;
+
+
+    my $db = tie %hash, 'BerkeleyDB::Btree',
+    		-Filename   => $filename,
+	        -Flags      => DB_CREATE
+      or die "Cannot open $filename: $!\n" ;
+
+    $db->filter_fetch_key  ( sub { $_ = unpack("i", $_) } ) ;
+    $db->filter_store_key  ( sub { $_ = pack ("i", $_) } ) ;
+    $hash{123} = "def" ;
+    # ...
+    undef $db ;
+    untie %hash ;
+
+This time only two filters have been used -- we only need to manipulate
+the contents of the key, so it wasn't necessary to install any value
+filters.

+Both BerkeleyDB::Hash and BerkeleyDB::Btree can be used with the MLDBM
+module. The code fragment below shows how to open associate MLDBM with
+BerkeleyDB::Btree. To use BerkeleyDB::Hash just replace

+=head2 Sharing Databases With C Applications
+
+There is no technical reason why a Berkeley DB database cannot be

+
+The vast majority of problems that are reported in this area boil down

+are not. See L<An Example -- the NULL termination problem.> in the DBM

+B<DB_File> can be build with Berkeley DB 1.x, 2.x or 3.x, it only provides
+an interface to the functionality available in Berkeley DB 1.x. That

+=head1 DESCRIPTION
+
+B<NOTE: This document is still under construction. Expect it to be
+incomplete in places.>
+
+This Perl module provides an interface to most of the functionality
+available in Berkeley DB versions 2 and 3. In general it is safe to assume
+that the interface provided here to be identical to the Berkeley DB
+interface. The main changes have been to make the Berkeley DB API work
+in a Perl way. Note that if you are using Berkeley DB 2.x, the new
+features available in Berkeley DB 3.x are not available via this module.
+
+The reader is expected to be familiar with the Berkeley DB
+documentation. Where the interface provided here is identical to the
+Berkeley DB library and the... TODO
+
+The B<db_appinit>, B<db_cursor>, B<db_open> and B<db_txn> man pages are
+particularly relevant.
+
+The interface to Berkeley DB is implemented with a number of Perl
+classes.
+
+=head1 ENV CLASS
+
+The B<BerkeleyDB::Env> class provides an interface to the Berkeley DB
+function B<db_appinit> in Berkeley DB 2.x or B<db_env_create> and
+B<DBENV-E<gt>open> in Berkeley DB 3.x. Its purpose is to initialise a
+number of sub-systems that can then be used in a consistent way in all
+the databases you make use of the environment.
+
+If you don't intend using transactions, locking or logging, then you
+shouldn't need to make use of B<BerkeleyDB::Env>.
+
+=head2 Synopsis
+
+    $env = new BerkeleyDB::Env
+             [ -Home         => $path, ]
+             [ -Server       => $name, ]

+
+All the parameters to the BerkeleyDB::Env constructor are optional.
+
+=item -Home
+
+If present, this parameter should point to an existing directory. Any
+files that I<aren't> specified with an absolute path in the sub-systems
+that are initialised by the BerkeleyDB::Env class will be assumed to
+live in the B<Home> directory.
+
+For example, in the code fragment below the database "fred.db" will be
+opened in the directory "/home/databases" because it was specified as a
+relative path, but "joe.db" will be opened in "/other" because it was
+part of an absolute path.
+
+    $env = new BerkeleyDB::Env
+             -Home         => "/home/databases"
+    ...
+
+    $db1 = new BerkeleyDB::Hash
+	     -Filename = "fred.db",
+	     -Env => $env
+    ...
+
+    $db2 = new BerkeleyDB::Hash
+	     -Filename = "/other/joe.db",
+	     -Env => $env
+    ...
+
+=item -Server
+
+If present, this parameter should be the hostname of a server that is running
+the Berkeley DB RPC server. All databases will be accessed via the RPC server.
+
+=item -Cachesize
+
+If present, this parameter sets the size of the environments shared memory
+buffer pool.
+
+=item -Config
+
+This is a variation on the C<-Home> parameter, but it allows finer
+control of where specific types of files will be stored.
+
+The parameter expects a reference to a hash. Valid keys are:
+B<DB_DATA_DIR>, B<DB_LOG_DIR> and B<DB_TMP_DIR>
+
+The code below shows an example of how it can be used.
+
+    $env = new BerkeleyDB::Env
+             -Config => { DB_DATA_DIR => "/home/databases",
+                          DB_LOG_DIR  => "/home/logs",
+                          DB_TMP_DIR  => "/home/tmp"
+                        }
+    ...
+
+=item -ErrFile
+
+Expects either the name of a file or a reference to a filehandle. Any
+errors generated internally by Berkeley DB will be logged to this file.
+
+=item -ErrPrefix
+
+Allows a prefix to be added to the error messages before they are sent
+to B<-ErrFile>.
+
+=item -Flags
+
+The B<Flags> parameter specifies both which sub-systems to initialise,
+as well as a number of environment-wide options.
+See the Berkeley DB documentation for more details of these options.
+
+Any of the following can be specified by OR'ing them:

+
+=head1 THE DATABASE CLASSES
+
+B<BerkeleyDB> supports the following database formats:
+
+=over 5
+
+=item B<BerkeleyDB::Hash>
+
+This database type allows arbitrary key/value pairs to be stored in data
+files. This is equivalent to the functionality provided by other
+hashing packages like DBM, NDBM, ODBM, GDBM, and SDBM. Remember though,
+the files created using B<BerkeleyDB::Hash> are not compatible with any
+of the other packages mentioned.
+
+A default hashing algorithm, which will be adequate for most applications,
+is built into BerkeleyDB. If you do need to use your own hashing algorithm
+it is possible to write your own in Perl and have B<BerkeleyDB> use
+it instead.
+
+=item B<BerkeleyDB::Btree>
+

+
+In addition to the standard set of options (see L<COMMON OPTIONS>)
+B<BerkeleyDB::Hash> supports these options:

+
+=item -Property
+
+Used to specify extra flags when opening a database. The following
+flags may be specified by logically OR'ing together one or more of the
+following values:
+
+B<DB_DUP>
+
+When creating a new database, this flag enables the storing of duplicate
+keys in the database. If B<DB_DUPSORT> is not specified as well, the
+duplicates are stored in the order they are created in the database.
+
+B<DB_DUPSORT>
+
+Enables the sorting of duplicate keys in the database. Ignored if
+B<DB_DUP> isn't also specified.
+
+=item -Ffactor
+
+=item -Nelem
+
+See the Berkeley DB documentation for details of these options.
+
+=item -Hash
+
+Allows you to provide a user defined hash function. If not specified, 
+a default hash function is used. Here is a template for a user-defined
+hash function
+
+    sub hash
+    {
+        my ($data) = shift ;

+    	-Hash     => \&hash,
+	...
+
+See L<""> for an example.
+
+=item -DupCompare
+
+Used in conjunction with the B<DB_DUPOSRT> flag. 
+
+    sub compare
+    {
+	my ($key, $key2) = @_ ;
+        ...
+        # return  0 if $key1 eq $key2

+=head1 COMMON DATABASE METHODS
+
+All the database interfaces support the common set of methods defined
+below.
+
+All the methods below return 0 to indicate success.
+
+=head2 $status = $db->db_get($key, $value [, $flags])
+
+Given a key (C<$key>) this method reads the value associated with it
+from the database. If it exists, the value read from the database is
+returned in the C<$value> parameter.
+
+The B<$flags> parameter is optional. If present, it must be set to B<one>
+of the following values:
+
+=over 5
+
+=item B<DB_GET_BOTH>
+
+When the B<DB_GET_BOTH> flag is specified, B<db_get> checks for the
+existence of B<both> the C<$key> B<and> C<$value> in the database.
+
+=item B<DB_SET_RECNO>
+
+TODO.
+
+=back
+
+In addition, the following value may be set by logically OR'ing it into
+the B<$flags> parameter:
+
+=over 5
+
+=item B<DB_RMW>
+
+TODO
+
+=back
+
+
+=head2 $status = $db->db_put($key, $value [, $flags])
+
+Stores a key/value pair in the database.
+
+The B<$flags> parameter is optional. If present it must be set to B<one>
+of the following values:
+
+=over 5
+
+=item B<DB_APPEND>
+
+This flag is only applicable when accessing a B<BerkeleyDB::Recno>
+database.
+
+TODO.
+
+
+=item B<DB_NOOVERWRITE>
+
+If this flag is specified and C<$key> already exists in the database,
+the call to B<db_put> will return B<DB_KEYEXIST>.
+
+=back
+
+=head2 $status = $db->db_del($key [, $flags])
+
+Deletes a key/value pair in the database associated with C<$key>.
+If duplicate keys are enabled in the database, B<db_del> will delete
+B<all> key/value pairs with key C<$key>.
+
+The B<$flags> parameter is optional and is currently unused.
+
+=head2 $status = $db->db_sync()
+
+If any parts of the database are in memory, write them to the database.
+
+=head2 $cursor = $db->db_cursor([$flags])
+
+Creates a cursor object. This is used to access the contents of the
+database sequentially. See L<CURSORS> for details of the methods
+available when working with cursors.
+
+The B<$flags> parameter is optional. If present it must be set to B<one>
+of the following values:
+
+=over 5
+
+=item B<DB_RMW>
+
+TODO.
+
+=back
+
+=head2 ($flag, $old_offset, $old_length) = $db->partial_set($offset, $length) ;
+
+TODO
+
+=head2 ($flag, $old_offset, $old_length) = $db->partial_clear() ;
+
+TODO
+
+=head2 $db->byteswapped()
+
+TODO
+
+=head2 $db->type()
+
+Returns the type of the database. The possible return code are B<DB_HASH>
+for a B<BerkeleyDB::Hash> database, B<DB_BTREE> for a B<BerkeleyDB::Btree>
+database and B<DB_RECNO> for a B<BerkeleyDB::Recno> database. This method
+is typically used when a database has been opened with
+B<BerkeleyDB::Unknown>.
+
+=item $ref = $db->db_stat()
+
+Returns a reference to an associative array containing information about
+the database. The keys of the associative array correspond directly to the
+names of the fields defined in the Berkeley DB documentation. For example,
+in the DB documentation, the field B<bt_version> stores the version of the
+Btree database. Assuming you called B<db_stat> on a Btree database the
+equivalent field would be accessed as follows:
+
+    $version = $ref->{'bt_version'} ;
+
+If you are using Berkeley DB 3.x, this method will work will all database
+formats. When DB 2.x is used, it only works with B<BerkeleyDB::Btree>.
+
+=head2 $status = $db->status()
+
+Returns the status of the last C<$db> method called.
+
+=head1 CURSORS
+
+A cursor is used whenever you want to access the contents of a database
+in sequential order.
+A cursor object is created with the C<db_cursor>
+
+A cursor object has the following methods available:
+
+=head2 $newcursor = $cursor->c_dup($flags)
+
+Creates a duplicate of C<$cursor>. This method needs Berkeley DB 3.0.x or better.
+
+The C<$flags> parameter is optional and can take the following value:
+
+=over 5
+
+=item DB_POSITION
+
+When present this flag will position the new cursor at the same place as the
+existing cursor.
+
+=back
+
+=head2 $status = $cursor->c_get($key, $value, $flags)
+
+Reads a key/value pair from the database, returning the data in C<$key>
+and C<$value>. The key/value pair actually read is controlled by the
+C<$flags> parameter, which can take B<one> of the following values:
+
+=over 5
+
+=item B<DB_FIRST>
+
+Set the cursor to point to the first key/value pair in the
+database. Return the key/value pair in C<$key> and C<$value>.
+
+=item B<DB_LAST>
+
+Set the cursor to point to the last key/value pair in the database. Return
+the key/value pair in C<$key> and C<$value>.
+
+=item B<DB_NEXT>
+
+If the cursor is already pointing to a key/value pair, it will be
+incremented to point to the next key/value pair and return its contents.
+
+If the cursor isn't initialised, B<DB_NEXT> works just like B<DB_FIRST>.
+
+If the cursor is already positioned at the last key/value pair, B<c_get>
+will return B<DB_NOTFOUND>.
+
+=item B<DB_NEXT_DUP>
+
+This flag is only valid when duplicate keys have been enabled in
+a database.
+If the cursor is already pointing to a key/value pair and the key of
+the next key/value pair is identical, the cursor will be incremented to
+point to it and their contents returned.
+
+=item B<DB_PREV>
+
+If the cursor is already pointing to a key/value pair, it will be
+decremented to point to the previous key/value pair and return its
+contents.
+
+If the cursor isn't initialised, B<DB_PREV> works just like B<DB_LAST>.
+
+If the cursor is already positioned at the first key/value pair, B<c_get>
+will return B<DB_NOTFOUND>.
+
+=item B<DB_CURRENT>
+
+If the cursor has been set to point to a key/value pair, return their
+contents.
+If the key/value pair referenced by the cursor has been deleted, B<c_get>
+will return B<DB_KEYEMPTY>.
+
+=item B<DB_SET>
+
+Set the cursor to point to the key/value pair referenced by B<$key>
+and return the value in B<$value>.
+
+=item B<DB_SET_RANGE>
+
+This flag is a variation on the B<DB_SET> flag. As well as returning
+the value, it also returns the key, via B<$key>.
+When used with a B<BerkeleyDB::Btree> database the key matched by B<c_get>
+will be the shortest key (in length) which is greater than or equal to
+the key supplied, via B<$key>. This allows partial key searches.
+See ??? for an example of how to use this flag.
+
+=item B<DB_GET_BOTH>
+
+Another variation on B<DB_SET>. This one returns both the key and
+the value.
+
+=item B<DB_SET_RECNO>
+
+TODO.

+=item B<DB_GET_RECNO>
+
+TODO.

+=over 5
+
+=item B<DB_RMW>
+
+TODO.
+
+=back
+
+=head2  $status = $cursor->c_put($key, $value, $flags)
+
+Stores the key/value pair in the database. The position that the data is
+stored in the database is controlled by the C<$flags> parameter, which
+must take B<one> of the following values:
+
+=over 5
+
+=item B<DB_AFTER>
+
+When used with a Btree or Hash database, a duplicate of the key referenced
+by the current cursor position will be created and the contents of
+B<$value> will be associated with it - B<$key> is ignored.
+The new key/value pair will be stored immediately after the current
+cursor position.
+Obviously the database has to have been opened with B<DB_DUP>.
+
+When used with a Recno ... TODO
+
+
+=item B<DB_BEFORE>
+
+When used with a Btree or Hash database, a duplicate of the key referenced
+by the current cursor position will be created and the contents of
+B<$value> will be associated with it - B<$key> is ignored.
+The new key/value pair will be stored immediately before the current
+cursor position.
+Obviously the database has to have been opened with B<DB_DUP>.

+
+If the cursor has been initialised, replace the value of the key/value
+pair stored in the database with the contents of B<$value>.
+
+=item B<DB_KEYFIRST>
+
+Only valid with a Btree or Hash database. This flag is only really
+used when duplicates are enabled in the database and sorted duplicates
+haven't been specified.
+In this case the key/value pair will be inserted as the first entry in
+the duplicates for the particular key.
+
+=item B<DB_KEYLAST>
+
+Only valid with a Btree or Hash database. This flag is only really
+used when duplicates are enabled in the database and sorted duplicates
+haven't been specified.
+In this case the key/value pair will be inserted as the last entry in
+the duplicates for the particular key.
+
+=back
+
+=head2  $status = $cursor->c_del([$flags])
+
+This method deletes the key/value pair associated with the current cursor
+position. The cursor position will not be changed by this operation, so
+any subsequent cursor operation must first initialise the cursor to
+point to a valid key/value pair.
+
+If the key/value pair associated with the cursor have already been
+deleted, B<c_del> will return B<DB_KEYEMPTY>.
+
+The B<$flags> parameter is not used at present.
+
+=head2 $status = $cursor->c_del($cnt [, $flags])
+
+Stores the number of duplicates at the current cursor position in B<$cnt>.
+
+The B<$flags> parameter is not used at present. This method needs 
+Berkeley DB 3.1 or better.
+
+=head2  $status = $cursor->status()
+
+Returns the status of the last cursor method as a dual type.

+
+=head1 DBM Filters
+
+A DBM Filter is a piece of code that is be used when you I<always>
+want to make the same transformation to all keys and/or values in a DBM
+database. All of the database classes (BerkeleyDB::Hash,
+BerkeleyDB::Btree and BerkeleyDB::Recno) support DBM Filters.
+
+There are four methods associated with DBM Filters. All work
+identically, and each is used to install (or uninstall) a single DBM
+Filter. Each expects a single parameter, namely a reference to a sub.
+The only difference between them is the place that the filter is
+installed.
+
+To summarise:
+
+=over 5
+
+=item B<filter_store_key>
+
+If a filter has been installed with this method, it will be invoked
+every time you write a key to a DBM database.
+
+=item B<filter_store_value>
+
+If a filter has been installed with this method, it will be invoked
+every time you write a value to a DBM database.
+
+
+=item B<filter_fetch_key>
+
+If a filter has been installed with this method, it will be invoked
+every time you read a key from a DBM database.
+
+=item B<filter_fetch_value>
+
+If a filter has been installed with this method, it will be invoked
+every time you read a value from a DBM database.
+
+=back
+
+You can use any combination of the methods, from none, to all four.
+
+All filter methods return the existing filter, if present, or C<undef>
+in not.
+
+To delete a filter pass C<undef> to it.
+
+=head2 The Filter
+
+When each filter is called by Perl, a local copy of C<$_> will contain
+the key or value to be filtered. Filtering is achieved by modifying
+the contents of C<$_>. The return code from the filter is ignored.
+
+=head2 An Example -- the NULL termination problem.
+
+Consider the following scenario. You have a DBM database that you need
+to share with a third-party C application. The C application assumes
+that I<all> keys and values are NULL terminated. Unfortunately when
+Perl writes to DBM databases it doesn't use NULL termination, so your
+Perl application will have to manage NULL termination itself. When you
+write to the database you will have to use something like this:
+
+    $hash{"$key\0"} = "$value\0" ;
+
+Similarly the NULL needs to be taken into account when you are considering
+the length of existing keys/values.
+
+It would be much better if you could ignore the NULL terminations issue
+in the main application code and have a mechanism that automatically
+added the terminating NULL to all keys and values whenever you write to
+the database and have them removed when you read from the database. As I'm
+sure you have already guessed, this is a problem that DBM Filters can
+fix very easily.
+
+## nullFilter
+
+Hopefully the contents of each of the filters should be
+self-explanatory. Both "fetch" filters remove the terminating NULL,
+and both "store" filters add a terminating NULL.
+
+
+=head2 Another Example -- Key is a C int.
+
+Here is another real-life example. By default, whenever Perl writes to
+a DBM database it always writes the key and value as strings. So when
+you use this:
+
+    $hash{12345} = "something" ;
+
+the key 12345 will get stored in the DBM database as the 5 byte string
+"12345". If you actually want the key to be stored in the DBM database
+as a C int, you will have to use C<pack> when writing, and C<unpack>
+when reading.
+
+Here is a DBM Filter that does it:
+
+## intFilter
+
+This time only two filters have been used -- we only need to manipulate
+the contents of the key, so it wasn't necessary to install any value
+filters.
+
+=head1 Using BerkeleyDB with MLDBM
+
+Both BerkeleyDB::Hash and BerkeleyDB::Btree can be used with the MLDBM
+module. The code fragment below shows how to open associate MLDBM with
+BerkeleyDB::Btree. To use BerkeleyDB::Hash just replace
+BerkeleyDB::Btree with BerkeleyDB::Hash.
+
+    use strict ;
+    use BerkeleyDB ;
+    use MLDBM qw(BerkeleyDB::Btree) ;
+    use Data::Dumper;
+ 
+    my $filename = 'testmldbm' ;
+    my %o ;
+     
+    unlink $filename ;
+    tie %o, 'MLDBM', -Filename => $filename,
+                     -Flags    => DB_CREATE
+                    or die "Cannot open database '$filename: $!\n";
+ 
+See the MLDBM documentation for information on how to use the module
+and for details of its limitations.

+
+=head1 HINTS & TIPS
+
+=head2 Sharing Databases With C Applications
+
+There is no technical reason why a Berkeley DB database cannot be
+shared by both a Perl and a C application.
+
+The vast majority of problems that are reported in this area boil down
+to the fact that C strings are NULL terminated, whilst Perl strings
+are not. See L<An Example -- the NULL termination problem.> in the DBM
+FILTERS section for a generic way to work around this problem.
+
+
+=head2 The untie Gotcha
+
+TODO
+
+=head1 COMMON QUESTIONS
+
+This section attempts to answer some of the more common questions that
+I get asked.
+
+
+=head2 Relationship with DB_File
+
+Before Berkeley DB 2.x was written there was only one Perl module that
+interfaced to Berkeley DB. That module is called B<DB_File>. Although
+B<DB_File> can be build with Berkeley DB 1.x, 2.x or 3.x, it only provides
+an interface to the functionality available in Berkeley DB 1.x. That
+means that it doesn't support transactions, locking or any of the other
+new features available in DB 2.x or 3.x.
+
+=head2 How do I store Perl data structures with BerkeleyDB?
+
+See L<Using BerkeleyDB with MLDBM>.
+
+=head1 HISTORY
+
+See the Changes file.
+
+=head1 AVAILABILITY
+
+The most recent version of B<BerkeleyDB> can always be found
+on CPAN (see L<perlmod/CPAN> for details), in the directory
+F<modules/by-module/BerkeleyDB>.
+
+The official web site for Berkeley DB is F<http://www.sleepycat.com>.

+Revision history for Perl extension BerkeleyDB.
+
+0.01  23 October 1997
+	* first alpha release as BerkDB.
+
+0.02  30 October 1997
+	* renamed module to BerkeleyDB	
+	* fixed a few bugs & added more tests
+
+0.03  5 May 1998
+	* fixed db_get with DB_SET_RECNO
+	* fixed c_get with DB_SET_RECNO and DB_GET_RECNO
+	* implemented BerkeleyDB::Unknown
+	* implemented BerkeleyDB::Recno, including push, pop etc
+	  modified the txn support. 
+
+0.04  19 May 1998
+	* Define DEFSV & SAVE_DEFSV if not already defined. This allows
+	  the module to be built with Perl 5.004_04.
+
+0.05  9 November 1998
+	* Added a note to README about how to build Berkeley DB 2.x
+	  when using HP-UX.
+	* Minor modifications to get the module to build with DB 2.5.x
+
+0.06  19 December 1998
+	* Minor modifications to get the module to build with DB 2.6.x
+	* Added support for DB 2.6.x's  Concurrent Access Method, DB_INIT_CDB.
+
+0.07  21st September 1999
+	* Numerous small bug fixes.
+	* Added support for sorting duplicate values DB_DUPSORT.
+	* Added support for DB_GET_BOTH & DB_NEXT_DUP.
+	* Added get_dup (from DB_File).
+	* beefed up the documentation.
+	* Forgot to add the DB_INIT_CDB in BerkeleyDB.pm in previous release.
+	* Merged the DBM Filter code from DB_File into BerkeleyDB.
+	* Fixed a nasty bug where a closed transaction was still used with
+	  with dp_put, db_get etc.
+	* Added logic to gracefully close everything whenever a fatal error
+	  happens. Previously the plug was just pulled.
+	* It is now a fatal error to explicitly close an environment if there
+	  is still an open database; a database when there are open cursors or
+	  an open transaction; and a cursor if there is an open transaction.
+	  Using object destruction doesn't have this issue, as object
+	  references will ensure everything gets closed in the correct order.
+	* The BOOT code now checks that the version of db.h & libdb are the
+	  same - this seems to be a common problem on Linux.
+	* MLDBM support added.  
+	* Support for the new join cursor added.
+	* Builds with Berkeley DB 3.x
+   	* Updated dbinfo for Berkeley DB 3.x file formats.
+	* Deprecated the TxnMgr class. As with Berkeley DB version 3,
+	  txn_begin etc are now accessed via the environment object.
+	
+0.08  28nd November 1999
+	* More documentation updates
+	* Changed reference to files in /tmp in examples.t
+	* Fixed a typo in softCrash that caused problems when building
+	  with a thread-enabled Perl.
+	* BerkeleyDB::Error wasn't initialised properly.
+	* ANSI-ified all the static C functions in BerkeleyDB.xs
+	* Added support for the following DB 3.x features:
+	    + The Queue database type
+	    + db_remove
+	    + subdatabases 
+	    + db_stat for Hash & Queue
+
+0.09  29th November 1999
+        * the queue.t & subdb.t test harnesses were outputting a few
+          spurious warnings. This has been fixed.
+
+0.10  8th December 1999
+	* The DESTROY method was missing for BerkeleyDB::Env. This resulted in
+	  a memory leak. Fixed.
+	* If opening an environment or database failed, there was a small 
+	  memory leak. This has been fixed. 
+	* A thread-enabled Perl it could core when a database was closed. 
+	  Problem traced to the strdup function.
+
+0.11  4th June 2000
+	* When built with Berkeley Db 3.x there can be a clash with the close
+	  macro.
+	* Typo in the definition of DB_WRITECURSOR
+	* The flags parameter wasn't getting sent to db_cursor
+	* Plugged small memory leak in db_cursor (DESTROY wasn't freeing
+	  memory)
+	* Can be built with Berkeley DB 3.1
+   
+
+0.12  2nd August 2000
+	* Serious bug with get fixed. Spotted by Sleepycat.
+	* Added hints file for Solaris & Irix (courtesy of Albert Chin-A-Young)
+
+0.13 15th January 2001
+        * Added support to allow this module to build with Berkeley DB 3.2  
+        * Updated dbinfo to support Berkeley DB 3.1 & 3.2 file format
+          changes.  
+        * Documented the Solaris 2.7 core dump problem in README.
+        * Tidied up the test harness to fix a problem on Solaris where the
+          "fred" directory wasn't being deleted when it should have been.
+        * two calls to "open" clashed with a win32 macro.
+        * size argument for hash_cb is different for Berkeley DB 3.x 
+        * Documented the issue of building on Linux.
+        * Added -Server, -CacheSize & -LockDetect options 
+          [original patch supplied by Graham Barr]
+        * Added support for set_mutexlocks, c_count, set_q_extentsize,
+          key_range, c_dup
+	* Dropped the "attempted to close a Cursor with an open transaction"
+	  error in c_close. The correct behaviour is that the cursor
+	  should be closed before committing/aborting the transaction.

+DESCRIPTION
+-----------
+
+BerkeleyDB is a module which allows Perl programs to make use of the
+facilities provided by Berkeley DB version 2 or 3. (Note: if you want
+to use version 1 of Berkeley DB with Perl you need the DB_File module).
+
+Berkeley DB is a C library which provides a consistent interface to a
+number of database formats. BerkeleyDB provides an interface to all
+four of the database types (hash, btree, queue and recno) currently
+supported by Berkeley DB.
+
+For further details see the documentation in the file BerkeleyDB.pod.
+
+PREREQUISITES
+-------------
+
+Before you can build BerkeleyDB you need to have the following
+installed on your system:
+
+    * Perl 5.004_04 or greater.
+
+    * Berkeley DB Version 2.6.4 or greater
+
+      The official web site for Berkeley DB is http://www.sleepycat.com
+
+      The latest version of Berkeley DB is always available there. It
+      is recommended that you use the most recent version available at
+      the Sleepycat site.
+
+      The one exception to this advice is where you want to use BerkeleyDB
+      to access database files created by a third-party application,
+      like Sendmail. In these cases you must build BerkeleyDB with a
+      compatible version of Berkeley DB.
+
+
+BUILDING THE MODULE
+-------------------
+
+Assuming you have met all the prerequisites, building the module should
+be relatively straightforward.
+
+Step 1 : If you are running Solaris 2.5, 2.7 or HP-UX 10 read either
+         the Solaris Notes or HP-UX Notes sections below.
+	 If you are running Linux please read the Linux Notes section
+         before proceeding.
+
+
+Step 2 : Edit the file config.in to suit you local installation.
+         Instructions are given in the file.
+
+Step 3 : Build and test the module using this sequence of commands:
+
+             perl Makefile.PL
+             make
+             make test
+
+INSTALLATION
+------------
+
+    make install
+
+TROUBLESHOOTING
+===============
+
+Here are some of the problems that people encounter when building BerkeleyDB.
+
+Missing db.h or libdb.a
+-----------------------
+
+If you get an error like this:
+
+  cc -c -I./libraries/ -Dbool=char -DHAS_BOOL -I/usr/local/include -O2
+  -DVERSION=\"0.07\" -DXS_VERSION=\"0.07\" -fpic
+  -I/usr/local/lib/perl5/5.00503/i586-linux/CORE  BerkeleyDB.c
+  BerkeleyDB.xs:52: db.h: No such file or directory
+
+or this:
+
+  cc -c -I./libraries/2.7.5 -Dbool=char -DHAS_BOOL -I/usr/local/include -O2
+  -DVERSION=\"0.07\" -DXS_VERSION=\"0.07\" -fpic
+  -I/usr/local/lib/perl5/5.00503/i586-linux/CORE  BerkeleyDB.c
+  LD_RUN_PATH="/lib" cc -o blib/arch/auto/BerkeleyDB/BerkeleyDB.so  -shared
+  -L/usr/local/lib BerkeleyDB.o
+  -L/home/paul/perl/ext/BerkDB/BerkeleyDB/libraries -ldb
+  ld: cannot open -ldb: No such file or directory
+
+This symptom can imply:
+
+ 1. You don't have Berkeley DB installed on your system at all.
+    Solution: get & install Berkeley DB.
+
+ 2. You do have Berkeley DB installed, but it isn't in a standard place.
+    Solution: Edit config.in and set the LIB and INCLUDE variables to point
+              to the directories where libdb.a and db.h are installed.
+
+Wrong db.h
+----------
+
+If you get an error like this when building this module:
+
+  cc -c -I./libraries/ -Dbool=char -DHAS_BOOL -I/usr/local/include -O2
+  -DVERSION=\"0.07\" -DXS_VERSION=\"0.07\" -fpic
+  -I/usr/local/lib/perl5/5.00503/i586-linux/CORE  BerkeleyDB.c
+  BerkeleyDB.xs:93: parse error before `DB_INFO'
+  BerkeleyDB.xs:93: warning: no semicolon at end of struct or union
+  BerkeleyDB.xs:94: warning: data definition has no type or storage class
+  BerkeleyDB.xs:95: parse error before `0x80000000'
+  BerkeleyDB.xs:110: parse error before `}'
+  BerkeleyDB.xs:110: warning: data definition has no type or storage class
+  BerkeleyDB.xs:117: parse error before `DB_ENV'
+  ...
+
+This error usually happens when if you only have Berkeley DB version 1
+on your system or you have both version 1 and version 2 (or 3) of Berkeley
+DB installed on your system. When building BerkeleyDB it attempts 
+to use the db.h for Berkeley DB version 1. This perl module can only
+be built with Berkeley DB version 2 or 3.
+
+This symptom can imply:
+
+ 1. You don't have Berkeley DB version 2 or 3 installed on your system
+    at all.
+    Solution: get & install Berkeley DB.
+
+ 2. You do have Berkeley DB 2 or 3 installed, but it isn't in a standard
+    place.
+    Solution: Edit config.in and set the LIB and INCLUDE variables
+              to point to the directories where libdb.a and db.h are
+              installed.
+
+Undefined Symbol: txn_stat 
+--------------------------
+
+BerkeleyDB seems to have built correctly, but you get an error like this
+when you run the test harness:
+
+  $ make test
+  PERL_DL_NONLAZY=1 /home/paul/perl/install/bin/perl5.00503
+  -Iblib/arch -Iblib/lib -I/usr/local/lib/perl5/5.00503/i586-linux
+  -I/usr/local/lib/perl5/5.00503 -e 'use Test::Harness qw(&runtests $verbose);
+  $verbose=0; runtests @ARGV;' t/*.t
+  t/btree.............Can't load 'blib/arch/auto/BerkeleyDB/BerkeleyDB.so' for
+  module BerkeleyDB: blib/arch/auto/BerkeleyDB/BerkeleyDB.so:
+  undefined symbol: txn_stat
+  at /usr/local/lib/perl5/5.00503/i586-linux/DynaLoader.pm line 169.
+  ...
+
+This error usually happens when you have both version 1 and version
+2 (or 3) of Berkeley DB installed on your system and BerkeleyDB attempts
+to build using the db.h for Berkeley DB version 2/3 and the version 1
+library. Unfortunately the two versions aren't compatible with each
+other. BerkeleyDB can only be built with Berkeley DB version 2 or 3.
+
+Solution: Setting the LIB & INCLUDE variables in config.in to point to the
+          correct directories can sometimes be enough to fix this
+          problem. If that doesn't work the easiest way to fix the
+          problem is to either delete or temporarily rename the copies
+          of db.h and libdb.a that you don't want BerkeleyDB to use.
+
+Undefined Symbol: db_appinit 
+----------------------------
+
+BerkeleyDB seems to have built correctly, but you get an error like this
+when you run the test harness:
+
+  $ make test

+  undefined symbol: db_appinit 
+  at /home/paul/perl/install/5.005_61/lib/5.00561/i586-linux/DynaLoader.pm 
+  ...
+
+
+This error usually happens when you have both version 2 and version
+3 of Berkeley DB installed on your system and BerkeleyDB attempts
+to build using the db.h for Berkeley DB version 2 and the version 3
+library. Unfortunately the two versions aren't compatible with each
+other. 
+
+Solution: Setting the LIB & INCLUDE variables in config.in to point to the
+          correct directories can sometimes be enough to fix this
+          problem. If that doesn't work the easiest way to fix the
+          problem is to either delete or temporarily rename the copies
+          of db.h and libdb.a that you don't want BerkeleyDB to use.
+
+Undefined Symbol: db_create
+---------------------------
+
+BerkeleyDB seems to have built correctly, but you get an error like this
+when you run the test harness:
+
+  $ make test   
+  PERL_DL_NONLAZY=1 /home/paul/perl/install/bin/perl5.00561 -Iblib/arch 
+  -Iblib/lib -I/home/paul/perl/install/5.005_61/lib/5.00561/i586-linux

+          problem is to either delete or temporarily rename the copies
+          of db.h and libdb.a that you don't want BerkeleyDB to use.
+
+
+Incompatible versions of db.h and libdb
+---------------------------------------
+
+BerkeleyDB seems to have built correctly, but you get an error like this
+when you run the test harness:
+
+  $ make test
+  PERL_DL_NONLAZY=1 /home/paul/perl/install/bin/perl5.00503
+  -Iblib/arch -Iblib/lib -I/usr/local/lib/perl5/5.00503/i586-linux
+  -I/usr/local/lib/perl5/5.00503 -e 'use Test::Harness qw(&runtests $verbose);
+  $verbose=0; runtests @ARGV;' t/*.t
+  t/btree.............
+  BerkeleyDB needs compatible versions of libdb & db.h
+          you have db.h version 2.6.4 and libdb version 2.7.5
+  BEGIN failed--compilation aborted at t/btree.t line 25.
+  dubious
+        Test returned status 255 (wstat 65280, 0xff00)
+  ...	
+
+Another variation on the theme of having two versions of Berkeley DB on
+your system. 
+
+Solution: Setting the LIB & INCLUDE variables in config.in to point to the
+          correct directories can sometimes be enough to fix this
+          problem. If that doesn't work the easiest way to fix the
+          problem is to either delete or temporarily rename the copies
+          of db.h and libdb.a that you don't want BerkeleyDB to use.
+	  If you are running Linux, please read the Linux Notes section below.
+
+
+Linux Notes
+-----------
+
+Newer versions of Linux (e.g. RedHat 6, SuSe 6) ship with a C library
+that has version 2.x of Berkeley DB linked into it. This makes it
+difficult to build this module with anything other than the version of
+Berkeley DB that shipped with your Linux release. If you do try to use
+a different version of Berkeley DB you will most likely get the error
+described in the "Incompatible versions of db.h and libdb" section of
+this file.
+
+To make matters worse, prior to Perl 5.6.1, the perl binary itself
+*always* included the Berkeley DB library.
+
+If you want to use a newer version of Berkeley DB with this module, the
+easiest solution is to use Perl 5.6.1 (or better) and Berkeley DB 3.x
+(or better).
+
+There are two approaches you can use to get older versions of Perl to
+work with specific versions of Berkeley DB. Both have their advantages
+and disadvantages.
+
+The first approach will only work when you want to build a version of
+Perl older than 5.6.1 along with Berkeley DB 3.x. If you want to use
+Berkeley DB 2.x, you must use the next approach. This approach involves
+rebuilding your existing version of Perl after applying an unofficial
+patch. The "patches" directory in the this module's source distribution
+contains a number of patch files. There is one patch file for every
+stable version of Perl since 5.004. Apply the appropriate patch to your
+Perl source tree before re-building and installing Perl from scratch.
+For example, assuming you are in the top-level source directory for
+Perl 5.6.0, the command below will apply the necessary patch. Remember
+to replace the path shown below with one that points to this module's
+patches directory.
+
+    patch -p1 -N </path/to/BerkeleyDB/patches/5.6.0
+
+Now rebuild & install perl. You should now have a perl binary that can
+be used to build this module. Follow the instructions in "BUILDING THE
+MODULE", remembering to set the INCLUDE and LIB variables in config.in.
+
+
+The second approach will work with both Berkeley DB 2.x and 3.x.
+Start by building Berkeley DB as a shared library. This is from
+the Berkeley DB build instructions:
+
+    Building Shared Libraries for the GNU GCC compiler
+
+    If you're using gcc and there's no better shared library example for
+    your architecture, the following shared library build procedure will
+    probably work.
+
+    Add the -fpic option to the CFLAGS value in the Makefile.
+
+    Rebuild all of your .o files. This will create a Berkeley DB library
+    that contains .o files with PIC code. To build the shared library,
+    then take the following steps in the library build directory:
+
+    % mkdir tmp
+    % cd tmp
+    % ar xv ../libdb.a
+    % gcc -shared -o libdb.so *.o
+    % mv libdb.so ..
+    % cd ..
+    % rm -rf tmp
+
+    Note, you may have to change the gcc line depending on the
+    requirements of your system.
+
+    The file libdb.so is your shared library
+
+Once you have built libdb.so, you will need to store it somewhere safe.
+
+    cp libdb.so /usr/local/BerkeleyDB/lib
+
+If you now set the LD_PRELOAD environment variable to point to this
+shared library, Perl will use it instead of the version of Berkeley DB
+that shipped with your Linux distribution.
+
+    export LD_PRELOAD=/usr/local/BerkeleyDB/lib/libdb.so
+
+Finally follow the instructions in "BUILDING THE MODULE" to build,
+test and install this module. Don't forget to set the INCLUDE and LIB
+variables in config.in.
+
+Remember, you will need to have the LD_PRELOAD variable set anytime you
+want to use Perl with Berkeley DB. Also note that if you have LD_PRELOAD
+permanently set it will affect ALL commands you execute. This may be a
+problem if you run any commands that access a database created by the
+version of Berkeley DB that shipped with your Linux distribution.
+
+
+
+Solaris 2.5 Notes
+-----------------
+
+If you are running Solaris 2.5, and you get this error when you run the
+BerkeleyDB test harness:
+
+    libc internal error: _rmutex_unlock: rmutex not held.
+
+you probably need to install a Sun patch. It has been reported that
+Sun patch 103187-25 (or later revisions) fixes this problem.
+
+To find out if you have the patch installed, the command "showrev -p"
+will display the patches that are currently installed on your system.
+
+Solaris 2.7 Notes
+-----------------
+
+If you are running Solaris 2.7 and all the tests in the test harness
+generate a core dump, try applying Sun patch 106980-09 (or better).
+
+To find out if you have the patch installed, the command "showrev -p"
+will display the patches that are currently installed on your system.
+
+
+HP-UX Notes
+-----------
+
+Some people running HP-UX 10 have reported getting an error like this
+when building this module with the native HP-UX compiler.
+
+    ld: (Warning) At least one PA 2.0 object file (BerkeleyDB.o) was detected.
+    The linked output may not run on a PA 1.x system.
+    ld: Invalid loader fixup for symbol "$000000A5".
+
+If this is the case for you, Berkeley DB needs to be recompiled with
+the +z or +Z option and the resulting library placed in a .sl file. The
+following steps should do the trick:
+
+  1: Configure the Berkeley DB distribution with the +z or +Z C compiler
+     flag:
+
+        env "CFLAGS=+z" ../dist/configure ...
+
+  2: Edit the Berkeley DB Makefile and change:
+
+        "libdb= libdb.a" to "libdb= libdb.sl".
+
+  3: Build and install the Berkeley DB distribution as usual.
+
+
+
+FEEDBACK
+--------
+
+How to report a problem with BerkeleyDB.
+
+To help me help you, I need of the following information:
+
+ 1. The version of Perl and the operating system name and version you
+    are running. The complete output from running "perl -V" will tell
+    me all I need to know.  
+    If your perl does not understand the "-V" option is too old.
+    BerkeleyDB needs Perl version 5.004_04 or better.
+
+ 2. The version of BerkeleyDB you have. If you have successfully
+    installed BerkeleyDB, this one-liner will tell you:
+
+       perl -MBerkeleyDB -e 'print "BerkeleyDB ver $BerkeleyDB::VERSION\n"'
+
+    If you haven't installed BerkeleyDB then search BerkeleyDB.pm for a
+    line like this:
+
+      $VERSION = "1.20" ;
+
+ 3. The version of Berkeley DB you have installed. If you have
+    successfully installed BerkeleyDB, this one-liner will tell you:
+
+        perl -MBerkeleyDB -e 'print BerkeleyDB::DB_VERSION_STRING."\n"'
+
+    If you haven't installed BerkeleyDB then search db.h for a line
+    like this:
+
+      #define DB_VERSION_STRING
+
+ 4. If you are having problems building BerkeleyDB, send me a complete
+    log of what happened.
+
+ 5. Now the difficult one. If you think you have found a bug in
+    BerkeleyDB and you want me to fix it, you will *greatly* enhance
+    the chances of me being able to track it down by sending me a small
+    self-contained Perl script that illustrates the problem you are
+    encountering. Include a summary of what you think the problem is
+    and a log of what happens when you run the script, in case I can't
+    reproduce your problem on my system. If possible, don't have the
+    script dependent on an existing 20Meg database. If the script you
+    send me can create the database itself then that is preferred.
+
+    I realise that in some cases this is easier said than done, so if
+    you can only reproduce the problem in your existing script, then
+    you can post me that if you want. Just don't expect me to find your
+    problem in a hurry, or at all. :-)

+
+  * Change the $BerkeleyDB::Error to store the info in the db object,
+    if possible.
+
+  * $BerkeleyDB::db_version is documented. &db_version isn't.
+
+  * migrate perl code into the .xs file where necessary
+
+  * convert as many of the DB examples files to BerkeleyDB format.
+
+  * add a method to the DB object to allow access to the environment (if there

+  * use '~' magic to store the inner data.

+  * for the get stuff zap the value to undef if it doesn't find the
+    key. This may be more intuitive for those folks who are used with
+    the $hash{key} interface.
+
+  * Text interface? This can be done as via Recno
+
+  * allow recno to allow base offset for arrays to be either 0 or 1.
+

+#    If you have copies of both 1.x and 2.x Berkeley DB installed on

+#    include the version number of the library can help.
+#
+#    For example, if you have Berkeley DB 2.6.4  you could rename the
+#    Berkeley DB library from libdb.a to libdb-2.6.4.a  and change the
+#    DBNAME line below to look like this:
+#
+#        DBNAME = -ldb-2.6.4 
+#
+#    Note: If you are building this module with Win32, -llibdb will be
+#    used by default.
+#
+#    If you have changed the name of the library, uncomment the line
+#    below (by removing the leading #) and edit the line to use the name
+#    you have picked.

+
+0.1
+
+    First Release.
+
+0.2
+
+    When DB_File is opening a database file it no longer terminates the
+    process if dbopen returned an error. This allows file protection
+    errors to be caught at run time. Thanks to Judith Grass
+    <grass@cybercash.com> for spotting the bug.
+
+0.3
+
+    Added prototype support for multiple btree compare callbacks.
+
+1.0
+
+    DB_File has been in use for over a year. To reflect that, the
+    version number has been incremented to 1.0.
+
+    Added complete support for multiple concurrent callbacks.
+
+    Using the push method on an empty list didn't work properly. This
+    has been fixed.
+
+1.01
+
+    Fixed a core dump problem with SunOS.
+
+    The return value from TIEHASH wasn't set to NULL when dbopen
+    returned an error.
+
+1.02
+
+    Merged OS/2 specific code into DB_File.xs
+
+    Removed some redundant code in DB_File.xs.
+
+    Documentation update.
+
+    Allow negative subscripts with RECNO interface.
+
+    Changed the default flags from O_RDWR to O_CREAT|O_RDWR.
+
+    The example code which showed how to lock a database needed a call
+    to sync added. Without it the resultant database file was empty.
+
+    Added get_dup method.
+
+1.03
+
+    Documentation update.
+
+    DB_File now imports the constants (O_RDWR, O_CREAT etc.) from Fcntl
+    automatically.
+
+    The standard hash function exists is now supported.
+
+    Modified the behavior of get_dup. When it returns an associative
+    array, the value is the count of the number of matching BTREE
+    values.
+
+1.04
+
+    Minor documentation changes.
+
+    Fixed a bug in hash_cb. Patches supplied by Dave Hammen,
+    <hammen@gothamcity.jsc.nasa.govt>.
+
+    Fixed a bug with the constructors for DB_File::HASHINFO,
+    DB_File::BTREEINFO and DB_File::RECNOINFO. Also tidied up the
+    constructors to make them -w clean.
+
+    Reworked part of the test harness to be more locale friendly.
+
+1.05
+
+    Made all scripts in the documentation strict and -w clean.
+
+    Added logic to DB_File.xs to allow the module to be built after
+    Perl is installed.
+
+1.06
+
+    Minor namespace cleanup: Localized PrintBtree.
+
+1.07
+
+    Fixed bug with RECNO, where bval wasn't defaulting to "\n".
+
+1.08
+
+    Documented operation of bval.
+
+1.09
+
+    Minor bug fix in DB_File::HASHINFO, DB_File::RECNOINFO and
+    DB_File::BTREEINFO.
+
+    Changed default mode to 0666.
+
+1.10
+
+    Fixed fd method so that it still returns -1 for in-memory files
+    when db 1.86 is used.
+
+1.11
+
+    Documented the untie gotcha.
+
+1.12
+
+    Documented the incompatibility with version 2 of Berkeley DB.
+
+1.13
+
+    Minor changes to DB_FIle.xs and DB_File.pm
+
+1.14
+
+    Made it illegal to tie an associative array to a RECNO database and
+    an ordinary array to a HASH or BTREE database.
+
+1.15
+
+    Patch from Gisle Aas <gisle@aas.no> to suppress "use of undefined
+    value" warning with db_get and db_seq.
+
+    Patch from Gisle Aas <gisle@aas.no> to make DB_File export only the
+    O_* constants from Fcntl.
+
+    Removed the DESTROY method from the DB_File::HASHINFO module.
+
+    Previously DB_File hard-wired the class name of any object that it
+    created to "DB_File". This makes sub-classing difficult. Now
+    DB_File creats objects in the namespace of the package it has been
+    inherited into.
+
+
+1.16
+
+   A harmless looking tab was causing Makefile.PL to fail on AIX 3.2.5
+
+    Small fix for the AIX strict C compiler XLC which doesn't like
+    __attribute__ being defined via proto.h and redefined via db.h. Fix
+    courtesy of Jarkko Hietaniemi.
+
+1.50
+
+    DB_File can now build with either DB 1.x or 2.x, but not both at
+    the same time.
+
+1.51
+
+    Fixed the test harness so that it doesn't expect DB_File to have
+    been installed by the main Perl build.
+
+
+    Fixed a bug in mapping 1.x O_RDONLY flag to 2.x DB_RDONLY equivalent
+
+1.52
+
+   Patch from Nick Ing-Simmons now allows DB_File to build on NT.
+   Merged 1.15 patch.
+
+1.53
+
+   Added DB_RENUMBER to flags for recno.
+
+1.54
+
+   Fixed a small bug in the test harness when run under win32
+   The emulation of fd when useing DB 2.x was busted.
+
+1.55
+   Merged 1.16 changes.
+
+1.56
+   Documented the Solaris 2.5 mutex bug
+
+1.57
+   If Perl has been compiled with Threads support,the symbol op will be
+   defined. This clashes with a field name in db.h, so it needs to be
+   #undef'ed before db.h is included.
+
+1.58
+   Tied Array support was enhanced in Perl 5.004_57. DB_File now
+   supports PUSH,POP,SHIFT,UNSHIFT & STORESIZE.
+
+   Fixed a problem with the use of sv_setpvn. When the size is
+   specified as 0, it does a strlen on the data.  This was ok for DB
+   1.x, but isn't for DB 2.x.
+
+1.59
+   Updated the license section.
+
+   Berkeley DB 2.4.10 disallows zero length keys. Tests 32 & 42 in
+   db-btree.t and test 27 in db-hash.t failed because of this change.
+   Those tests have been zapped.
+
+   Added dbinfo to the distribution.
+
+1.60
+   Changed the test to check for full tied array support
+
+1.61 19th November 1998
+
+   Added a note to README about how to build Berkeley DB 2.x when
+   using HP-UX.
+   Minor modifications to get the module to build with DB 2.5.x
+   Fixed a typo in the definition of O_RDONLY, courtesy of Mark Kettenis.
+
+1.62 30th November 1998
+
+   Added hints/dynixptx.pl.
+   Fixed typemap -- 1.61 used PL_na instead of na
+
+1.63 19th December 1998
+
+   * Fix to allow DB 2.6.x to build with DB_File
+   * Documentation updated to use push,pop etc in the RECNO example &
+     to include the find_dup & del_dup methods.
+
+1.64 21st February 1999
+
+   * Tidied the 1.x to 2.x flag mapping code.
+   * Added a patch from Mark Kettenis <kettenis@wins.uva.nl> to fix a flag
+     mapping problem with O_RDONLY on the Hurd
+   * Updated the message that db-recno.t prints when tests 51, 53 or 55 fail.
+
+1.65 6th March 1999
+
+   * Fixed a bug in the recno PUSH logic.
+   * The BOOT version check now needs 2.3.4 when using Berkeley DB version 2
+
+1.66 15th March 1999
+
+   * Added DBM Filter code
+
+1.67 6th June 1999
+
+   * Added DBM Filter documentation to DB_File.pm
+
+   * Fixed DBM Filter code to work with 5.004
+
+   * A few instances of newSVpvn were used in 1.66. This isn't available in
+     Perl 5.004_04 or earlier. Replaced with newSVpv.
+
+1.68 22nd July 1999
+
+   * Merged changes from 5.005_58 
+
+   * Fixed a bug in R_IBEFORE & R_IAFTER procesing in Berkeley DB
+     2 databases.
+
+   * Added some of the examples in the POD into the test harness.
+
+1.69 3rd August 1999
+
+   * fixed a bug in push -- DB_APPEND wasn't working properly.
+
+   * Fixed the R_SETCURSOR bug introduced in 1.68
+
+   * Added a new Perl variable $DB_File::db_ver
+   
+1.70 4th August 1999
+
+   * Initialise $DB_File::db_ver and $DB_File::db_version with
+     GV_ADD|GV_ADDMULT -- bug spotted by Nick Ing-Simmons.
+
+   * Added a BOOT check to test for equivalent versions of db.h &
+     libdb.a/so.
+
+1.71 7th September 1999
+
+   * Fixed a bug that prevented 1.70 from compiling under win32
+
+   * Updated to support Berkeley DB 3.x
+
+   * Updated dbinfo for Berkeley DB 3.x file formats.
+
+1.72 16th January 2000
+
+   * Added hints/sco.pl
+
+   * The module will now use XSLoader when it is available. When it
+     isn't it will use DynaLoader.
+
+   * The locking section in DB_File.pm has been discredited. Many thanks
+     to David Harris for spotting the underlying problem, contributing
+     the updates to the documentation and writing DB_File::Lock (available
+     on CPAN).
+
+1.73 31st May 2000
+
+   * Added support in version.c for building with threaded Perl.
+
+   * Berkeley DB 3.1 has reenabled support for null keys. The test
+     harness has been updated to reflect this.
+
+1.74 10th December 2000
+
+   * A "close" call in DB_File.xs needed parenthesised to stop win32 from
+     thinking it was one of its macros.
+
+   * Updated dbinfo to support Berkeley DB 3.1 file format changes.
+
+   * DB_File.pm & the test hasness now use the warnings pragma (when
+     available).
+
+   * Included Perl core patch 7703 -- size argument for hash_cb is different
+     for Berkeley DB 3.x
+
+   * Included Perl core patch 7801 -- Give __getBerkeleyDBInfo the ANSI C
+     treatment.
+
+   * @a = () produced the warning 'Argument "" isn't numeric in entersub'
+     This has been fixed. Thanks to Edward Avis for spotting this bug.
+
+   * Added note about building under Linux. Included patches.
+
+   * Included Perl core patch 8068 -- fix for bug 20001013.009

+     "Uninitialized value" warning. This has been fixed.
+
+1.75 17th December 2000
+
+   * Fixed perl core patch 7703
+
+   * Added suppport to allow DB_File to be built with Berkeley DB 3.2 --
+     btree_compare, btree_prefix and hash_cb needed to be changed.

+   * Updated dbinfo to support Berkeley DB 3.2 file format changes.
+
+
+1.76 15th January 2001
+
+   * Added instructions for using LD_PRELOAD to get Berkeley DB 2.x to work
+     with DB_File on Linux. Thanks to Norbert Bollow for sending details of

+=head1 DESCRIPTION
+
+B<DB_File> is a module which allows Perl programs to make use of the
+facilities provided by Berkeley DB version 1.x (if you have a newer
+version of DB, see L<Using DB_File with Berkeley DB version 2 or 3>).
+It is assumed that you have a copy of the Berkeley DB manual pages at
+hand when reading this documentation. The interface defined here
+mirrors the Berkeley DB interface closely.
+
+Berkeley DB is a C library which provides a consistent interface to a
+number of database formats.  B<DB_File> provides an interface to all
+three of the database types currently supported by Berkeley DB.
+
+The file types are:
+
+=over 5
+
+=item B<DB_HASH>
+
+This database type allows arbitrary key/value pairs to be stored in data
+files. This is equivalent to the functionality provided by other
+hashing packages like DBM, NDBM, ODBM, GDBM, and SDBM. Remember though,
+the files created using DB_HASH are not compatible with any of the
+other packages mentioned.
+
+A default hashing algorithm, which will be adequate for most
+applications, is built into Berkeley DB. If you do need to use your own
+hashing algorithm it is possible to write your own in Perl and have
+B<DB_File> use it instead.
+
+=item B<DB_BTREE>
+
+The btree format allows arbitrary key/value pairs to be stored in a
+sorted, balanced binary tree.
+
+As with the DB_HASH format, it is possible to provide a user defined
+Perl routine to perform the comparison of keys. By default, though, the
+keys are stored in lexical order.
+
+=item B<DB_RECNO>
+
+DB_RECNO allows both fixed-length and variable-length flat text files
+to be manipulated using the same key/value pair interface as in DB_HASH
+and DB_BTREE.  In this case the key will consist of a record (line)
+number.
+
+=back
+
+=head2 Using DB_File with Berkeley DB version 2 or 3
+
+Although B<DB_File> is intended to be used with Berkeley DB version 1,
+it can also be used with version 2.or 3 In this case the interface is
+limited to the functionality provided by Berkeley DB 1.x. Anywhere the
+version 2 or 3 interface differs, B<DB_File> arranges for it to work
+like version 1. This feature allows B<DB_File> scripts that were built
+with version 1 to be migrated to version 2 or 3 without any changes.
+
+If you want to make use of the new features available in Berkeley DB
+2.x or greater, use the Perl module B<BerkeleyDB> instead.
+
+B<Note:> The database file format has changed in both Berkeley DB
+version 2 and 3. If you cannot recreate your databases, you must dump
+any existing databases with the C<db_dump185> utility that comes with
+Berkeley DB.
+Once you have rebuilt DB_File to use Berkeley DB version 2 or 3, your
+databases can be recreated using C<db_load>. Refer to the Berkeley DB
+documentation for further details.
+
+Please read L<"COPYRIGHT"> before using version 2.x or 3.x of Berkeley
+DB with DB_File.
+
+=head2 Interface to Berkeley DB
+
+B<DB_File> allows access to Berkeley DB files using the tie() mechanism
+in Perl 5 (for full details, see L<perlfunc/tie()>). This facility
+allows B<DB_File> to access Berkeley DB files using either an
+associative array (for DB_HASH & DB_BTREE file types) or an ordinary
+array (for the DB_RECNO file type).
+
+In addition to the tie() interface, it is also possible to access most
+of the functions provided in the Berkeley DB API directly.
+See L<THE API INTERFACE>.
+
+=head2 Opening a Berkeley DB Database File
+
+Berkeley DB uses the function dbopen() to open or create a database.
+Here is the C prototype for dbopen():
+
+      DB*
+      dbopen (const char * file, int flags, int mode, 
+              DBTYPE type, const void * openinfo)
+
+The parameter C<type> is an enumeration which specifies which of the 3
+interface methods (DB_HASH, DB_BTREE or DB_RECNO) is to be used.
+Depending on which of these is actually chosen, the final parameter,
+I<openinfo> points to a data structure which allows tailoring of the
+specific interface method.
+
+This interface is handled slightly differently in B<DB_File>. Here is
+an equivalent call using B<DB_File>:
+
+        tie %array, 'DB_File', $filename, $flags, $mode, $DB_HASH ;
+
+The C<filename>, C<flags> and C<mode> parameters are the direct
+equivalent of their dbopen() counterparts. The final parameter $DB_HASH
+performs the function of both the C<type> and C<openinfo> parameters in
+dbopen().
+
+In the example above $DB_HASH is actually a pre-defined reference to a
+hash object. B<DB_File> has three of these pre-defined references.
+Apart from $DB_HASH, there is also $DB_BTREE and $DB_RECNO.
+
+The keys allowed in each of these pre-defined references is limited to
+the names used in the equivalent C structure. So, for example, the
+$DB_HASH reference will only allow keys called C<bsize>, C<cachesize>,
+C<ffactor>, C<hash>, C<lorder> and C<nelem>. 
+
+To change one of these elements, just assign to it like this:
+
+	$DB_HASH->{'cachesize'} = 10000 ;
+
+The three predefined variables $DB_HASH, $DB_BTREE and $DB_RECNO are
+usually adequate for most applications.  If you do need to create extra
+instances of these objects, constructors are available for each file
+type.
+
+Here are examples of the constructors and the valid options available
+for DB_HASH, DB_BTREE and DB_RECNO respectively.
+
+     $a = new DB_File::HASHINFO ;
+     $a->{'bsize'} ;
+     $a->{'cachesize'} ;
+     $a->{'ffactor'};
+     $a->{'hash'} ;
+     $a->{'lorder'} ;
+     $a->{'nelem'} ;
+
+     $b = new DB_File::BTREEINFO ;
+     $b->{'flags'} ;
+     $b->{'cachesize'} ;
+     $b->{'maxkeypage'} ;
+     $b->{'minkeypage'} ;
+     $b->{'psize'} ;
+     $b->{'compare'} ;
+     $b->{'prefix'} ;
+     $b->{'lorder'} ;
+
+     $c = new DB_File::RECNOINFO ;
+     $c->{'bval'} ;
+     $c->{'cachesize'} ;
+     $c->{'psize'} ;
+     $c->{'flags'} ;
+     $c->{'lorder'} ;
+     $c->{'reclen'} ;
+     $c->{'bfname'} ;
+
+The values stored in the hashes above are mostly the direct equivalent
+of their C counterpart. Like their C counterparts, all are set to a
+default values - that means you don't have to set I<all> of the
+values when you only want to change one. Here is an example:
+
+     $a = new DB_File::HASHINFO ;
+     $a->{'cachesize'} =  12345 ;
+     tie %y, 'DB_File', "filename", $flags, 0777, $a ;
+
+A few of the options need extra discussion here. When used, the C
+equivalent of the keys C<hash>, C<compare> and C<prefix> store pointers
+to C functions. In B<DB_File> these keys are used to store references
+to Perl subs. Below are templates for each of the subs:
+
+    sub hash
+    {
+        my ($data) = @_ ;
+        ...
+        # return the hash value for $data
+	return $hash ;
+    }
+
+    sub compare
+    {
+	my ($key, $key2) = @_ ;
+        ...
+        # return  0 if $key1 eq $key2
+        #        -1 if $key1 lt $key2
+        #         1 if $key1 gt $key2
+        return (-1 , 0 or 1) ;
+    }
+
+    sub prefix
+    {
+	my ($key, $key2) = @_ ;
+        ...
+        # return number of bytes of $key2 which are 
+        # necessary to determine that it is greater than $key1
+        return $bytes ;
+    }
+
+See L<Changing the BTREE sort order> for an example of using the
+C<compare> template.
+
+If you are using the DB_RECNO interface and you intend making use of
+C<bval>, you should check out L<The 'bval' Option>.
+
+=head2 Default Parameters
+
+It is possible to omit some or all of the final 4 parameters in the
+call to C<tie> and let them take default values. As DB_HASH is the most
+common file format used, the call:
+
+    tie %A, "DB_File", "filename" ;
+
+is equivalent to:
+
+    tie %A, "DB_File", "filename", O_CREAT|O_RDWR, 0666, $DB_HASH ;
+
+It is also possible to omit the filename parameter as well, so the
+call:
+
+    tie %A, "DB_File" ;
+
+is equivalent to:
+
+    tie %A, "DB_File", undef, O_CREAT|O_RDWR, 0666, $DB_HASH ;
+
+See L<In Memory Databases> for a discussion on the use of C<undef>
+in place of a filename.
+
+=head2 In Memory Databases
+
+Berkeley DB allows the creation of in-memory databases by using NULL
+(that is, a C<(char *)0> in C) in place of the filename.  B<DB_File>
+uses C<undef> instead of NULL to provide this functionality.
+
+=head1 DB_HASH
+
+The DB_HASH file format is probably the most commonly used of the three
+file formats that B<DB_File> supports. It is also very straightforward
+to use.
+
+=head2 A Simple Example
+
+This example shows how to create a database, add key/value pairs to the
+database, delete keys/value pairs and finally how to enumerate the
+contents of the database.
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+    use vars qw( %h $k $v ) ;
+
+    unlink "fruit" ;
+    tie %h, "DB_File", "fruit", O_RDWR|O_CREAT, 0640, $DB_HASH 
+        or die "Cannot open file 'fruit': $!\n";
+
+    # Add a few key/value pairs to the file
+    $h{"apple"} = "red" ;
+    $h{"orange"} = "orange" ;
+    $h{"banana"} = "yellow" ;
+    $h{"tomato"} = "red" ;
+
+    # Check for existence of a key
+    print "Banana Exists\n\n" if $h{"banana"} ;
+
+    # Delete a key/value pair.
+    delete $h{"apple"} ;
+
+    # print the contents of the file
+    while (($k, $v) = each %h)
+      { print "$k -> $v\n" }
+
+    untie %h ;
+
+here is the output:
+
+    Banana Exists
+ 
+    orange -> orange
+    tomato -> red
+    banana -> yellow
+
+Note that the like ordinary associative arrays, the order of the keys
+retrieved is in an apparently random order.
+
+=head1 DB_BTREE
+
+The DB_BTREE format is useful when you want to store data in a given
+order. By default the keys will be stored in lexical order, but as you
+will see from the example shown in the next section, it is very easy to
+define your own sorting function.
+
+=head2 Changing the BTREE sort order
+
+This script shows how to override the default sorting algorithm that
+BTREE uses. Instead of using the normal lexical ordering, a case
+insensitive compare function will be used.
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+
+    my %h ;
+
+    sub Compare
+    {
+        my ($key1, $key2) = @_ ;
+        "\L$key1" cmp "\L$key2" ;
+    }
+
+    # specify the Perl sub that will do the comparison
+    $DB_BTREE->{'compare'} = \&Compare ;
+
+    unlink "tree" ;
+    tie %h, "DB_File", "tree", O_RDWR|O_CREAT, 0640, $DB_BTREE 
+        or die "Cannot open file 'tree': $!\n" ;
+
+    # Add a key/value pair to the file
+    $h{'Wall'} = 'Larry' ;
+    $h{'Smith'} = 'John' ;
+    $h{'mouse'} = 'mickey' ;
+    $h{'duck'}  = 'donald' ;
+
+    # Delete
+    delete $h{"duck"} ;
+
+    # Cycle through the keys printing them in order.
+    # Note it is not necessary to sort the keys as
+    # the btree will have kept them in order automatically.
+    foreach (keys %h)
+      { print "$_\n" }
+
+    untie %h ;
+
+Here is the output from the code above.
+
+    mouse
+    Smith
+    Wall
+
+There are a few point to bear in mind if you want to change the
+ordering in a BTREE database:
+
+=over 5
+
+=item 1.
+
+The new compare function must be specified when you create the database.
+
+=item 2.
+
+You cannot change the ordering once the database has been created. Thus
+you must use the same compare function every time you access the
+database.
+
+=back 
+
+=head2 Handling Duplicate Keys 
+
+The BTREE file type optionally allows a single key to be associated
+with an arbitrary number of values. This option is enabled by setting
+the flags element of C<$DB_BTREE> to R_DUP when creating the database.
+
+There are some difficulties in using the tied hash interface if you
+want to manipulate a BTREE database with duplicate keys. Consider this
+code:
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+
+    use vars qw($filename %h ) ;
+
+    $filename = "tree" ;
+    unlink $filename ;
+ 
+    # Enable duplicate records
+    $DB_BTREE->{'flags'} = R_DUP ;
+ 
+    tie %h, "DB_File", $filename, O_RDWR|O_CREAT, 0640, $DB_BTREE 
+	or die "Cannot open $filename: $!\n";
+ 
+    # Add some key/value pairs to the file
+    $h{'Wall'} = 'Larry' ;
+    $h{'Wall'} = 'Brick' ; # Note the duplicate key
+    $h{'Wall'} = 'Brick' ; # Note the duplicate key and value
+    $h{'Smith'} = 'John' ;
+    $h{'mouse'} = 'mickey' ;
+
+    # iterate through the associative array
+    # and print each key/value pair.
+    foreach (sort keys %h)
+      { print "$_  -> $h{$_}\n" }
+
+    untie %h ;
+
+Here is the output:
+
+    Smith   -> John
+    Wall    -> Larry
+    Wall    -> Larry
+    Wall    -> Larry
+    mouse   -> mickey
+
+As you can see 3 records have been successfully created with key C<Wall>
+- the only thing is, when they are retrieved from the database they
+I<seem> to have the same value, namely C<Larry>. The problem is caused
+by the way that the associative array interface works. Basically, when
+the associative array interface is used to fetch the value associated
+with a given key, it will only ever retrieve the first value.
+
+Although it may not be immediately obvious from the code above, the
+associative array interface can be used to write values with duplicate
+keys, but it cannot be used to read them back from the database.
+
+The way to get around this problem is to use the Berkeley DB API method
+called C<seq>.  This method allows sequential access to key/value
+pairs. See L<THE API INTERFACE> for details of both the C<seq> method
+and the API in general.
+
+Here is the script above rewritten using the C<seq> API method.
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+ 
+    use vars qw($filename $x %h $status $key $value) ;
+
+    $filename = "tree" ;
+    unlink $filename ;
+ 
+    # Enable duplicate records
+    $DB_BTREE->{'flags'} = R_DUP ;
+ 
+    $x = tie %h, "DB_File", $filename, O_RDWR|O_CREAT, 0640, $DB_BTREE 
+	or die "Cannot open $filename: $!\n";
+ 
+    # Add some key/value pairs to the file
+    $h{'Wall'} = 'Larry' ;
+    $h{'Wall'} = 'Brick' ; # Note the duplicate key
+    $h{'Wall'} = 'Brick' ; # Note the duplicate key and value
+    $h{'Smith'} = 'John' ;
+    $h{'mouse'} = 'mickey' ;
+ 
+    # iterate through the btree using seq
+    # and print each key/value pair.
+    $key = $value = 0 ;
+    for ($status = $x->seq($key, $value, R_FIRST) ;
+         $status == 0 ;
+         $status = $x->seq($key, $value, R_NEXT) )
+      {  print "$key -> $value\n" }
+ 
+    undef $x ;
+    untie %h ;
+
+that prints:
+
+    Smith   -> John
+    Wall    -> Brick
+    Wall    -> Brick
+    Wall    -> Larry
+    mouse   -> mickey
+
+This time we have got all the key/value pairs, including the multiple
+values associated with the key C<Wall>.
+
+To make life easier when dealing with duplicate keys, B<DB_File> comes with 
+a few utility methods.
+
+=head2 The get_dup() Method
+
+The C<get_dup> method assists in
+reading duplicate values from BTREE databases. The method can take the
+following forms:
+
+    $count = $x->get_dup($key) ;
+    @list  = $x->get_dup($key) ;
+    %list  = $x->get_dup($key, 1) ;
+
+In a scalar context the method returns the number of values associated
+with the key, C<$key>.
+
+In list context, it returns all the values which match C<$key>. Note
+that the values will be returned in an apparently random order.
+
+In list context, if the second parameter is present and evaluates
+TRUE, the method returns an associative array. The keys of the
+associative array correspond to the values that matched in the BTREE
+and the values of the array are a count of the number of times that
+particular value occurred in the BTREE.
+
+So assuming the database created above, we can use C<get_dup> like
+this:
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+ 
+    use vars qw($filename $x %h ) ;
+
+    $filename = "tree" ;
+ 
+    # Enable duplicate records
+    $DB_BTREE->{'flags'} = R_DUP ;
+ 
+    $x = tie %h, "DB_File", $filename, O_RDWR|O_CREAT, 0640, $DB_BTREE 
+	or die "Cannot open $filename: $!\n";
+
+    my $cnt  = $x->get_dup("Wall") ;
+    print "Wall occurred $cnt times\n" ;
+
+    my %hash = $x->get_dup("Wall", 1) ;
+    print "Larry is there\n" if $hash{'Larry'} ;
+    print "There are $hash{'Brick'} Brick Walls\n" ;
+
+    my @list = sort $x->get_dup("Wall") ;
+    print "Wall =>	[@list]\n" ;
+
+    @list = $x->get_dup("Smith") ;
+    print "Smith =>	[@list]\n" ;
+ 
+    @list = $x->get_dup("Dog") ;
+    print "Dog =>	[@list]\n" ;
+
+
+and it will print:
+
+    Wall occurred 3 times
+    Larry is there
+    There are 2 Brick Walls
+    Wall =>	[Brick Brick Larry]
+    Smith =>	[John]
+    Dog =>	[]
+
+=head2 The find_dup() Method
+
+    $status = $X->find_dup($key, $value) ;
+
+This method checks for the existence of a specific key/value pair. If the
+pair exists, the cursor is left pointing to the pair and the method 
+returns 0. Otherwise the method returns a non-zero value.
+
+Assuming the database from the previous example:
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+ 
+    use vars qw($filename $x %h $found) ;
+
+    my $filename = "tree" ;
+ 
+    # Enable duplicate records
+    $DB_BTREE->{'flags'} = R_DUP ;
+ 
+    $x = tie %h, "DB_File", $filename, O_RDWR|O_CREAT, 0640, $DB_BTREE 
+	or die "Cannot open $filename: $!\n";
+
+    $found = ( $x->find_dup("Wall", "Larry") == 0 ? "" : "not") ; 
+    print "Larry Wall is $found there\n" ;
+    
+    $found = ( $x->find_dup("Wall", "Harry") == 0 ? "" : "not") ; 
+    print "Harry Wall is $found there\n" ;
+    
+    undef $x ;
+    untie %h ;
+
+prints this
+
+    Larry Wall is  there
+    Harry Wall is not there

+    $status = $X->del_dup($key, $value) ;
+
+This method deletes a specific key/value pair. It returns
+0 if they exist and have been deleted successfully.
+Otherwise the method returns a non-zero value.
+
+Again assuming the existence of the C<tree> database

+
+=head2 Matching Partial Keys 
+
+The BTREE interface has a feature which allows partial keys to be
+matched. This functionality is I<only> available when the C<seq> method
+is used along with the R_CURSOR flag.
+
+    $x->seq($key, $value, R_CURSOR) ;
+
+Here is the relevant quote from the dbopen man page where it defines
+the use of the R_CURSOR flag with seq:
+
+    Note, for the DB_BTREE access method, the returned key is not
+    necessarily an exact match for the specified key. The returned key
+    is the smallest key greater than or equal to the specified key,
+    permitting partial key matches and range searches.
+
+In the example script below, the C<match> sub uses this feature to find
+and print the first matching key/value pair given a partial key.
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+    use Fcntl ;
+
+    use vars qw($filename $x %h $st $key $value) ;
+
+    sub match
+    {
+        my $key = shift ;
+        my $value = 0;
+        my $orig_key = $key ;
+        $x->seq($key, $value, R_CURSOR) ;
+        print "$orig_key\t-> $key\t-> $value\n" ;
+    }
+
+    $filename = "tree" ;
+    unlink $filename ;
+
+    $x = tie %h, "DB_File", $filename, O_RDWR|O_CREAT, 0640, $DB_BTREE
+        or die "Cannot open $filename: $!\n";
+ 
+    # Add some key/value pairs to the file
+    $h{'mouse'} = 'mickey' ;
+    $h{'Wall'} = 'Larry' ;
+    $h{'Walls'} = 'Brick' ; 
+    $h{'Smith'} = 'John' ;
+ 
+
+    $key = $value = 0 ;
+    print "IN ORDER\n" ;
+    for ($st = $x->seq($key, $value, R_FIRST) ;
+	 $st == 0 ;
+         $st = $x->seq($key, $value, R_NEXT) )
+	
+      {  print "$key	-> $value\n" }
+ 
+    print "\nPARTIAL MATCH\n" ;
+
+    match "Wa" ;
+    match "A" ;
+    match "a" ;
+
+    undef $x ;
+    untie %h ;
+
+Here is the output:
+
+    IN ORDER
+    Smith -> John
+    Wall  -> Larry
+    Walls -> Brick
+    mouse -> mickey
+
+    PARTIAL MATCH
+    Wa -> Wall  -> Larry
+    A  -> Smith -> John
+    a  -> mouse -> mickey
+
+=head1 DB_RECNO
+
+DB_RECNO provides an interface to flat text files. Both variable and
+fixed length records are supported.
+
+In order to make RECNO more compatible with Perl, the array offset for
+all RECNO arrays begins at 0 rather than 1 as in Berkeley DB.
+
+As with normal Perl arrays, a RECNO array can be accessed using
+negative indexes. The index -1 refers to the last element of the array,
+-2 the second last, and so on. Attempting to access an element before
+the start of the array will raise a fatal run-time error.
+
+=head2 The 'bval' Option
+
+The operation of the bval option warrants some discussion. Here is the
+definition of bval from the Berkeley DB 1.85 recno manual page:
+
+    The delimiting byte to be used to mark  the  end  of  a
+    record for variable-length records, and the pad charac-
+    ter for fixed-length records.  If no  value  is  speci-
+    fied,  newlines  (``\n'')  are  used to mark the end of
+    variable-length records and  fixed-length  records  are
+    padded with spaces.
+
+The second sentence is wrong. In actual fact bval will only default to
+C<"\n"> when the openinfo parameter in dbopen is NULL. If a non-NULL
+openinfo parameter is used at all, the value that happens to be in bval
+will be used. That means you always have to specify bval when making
+use of any of the options in the openinfo parameter. This documentation
+error will be fixed in the next release of Berkeley DB.
+
+That clarifies the situation with regards Berkeley DB itself. What
+about B<DB_File>? Well, the behavior defined in the quote above is
+quite useful, so B<DB_File> conforms to it.
+
+That means that you can specify other options (e.g. cachesize) and
+still have bval default to C<"\n"> for variable length records, and
+space for fixed length records.
+
+=head2 A Simple Example
+
+Here is a simple example that uses RECNO (if you are using a version 
+of Perl earlier than 5.004_57 this example won't work -- see 
+L<Extra RECNO Methods> for a workaround).
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+
+    my $filename = "text" ;
+    unlink $filename ;
+
+    my @h ;
+    tie @h, "DB_File", $filename, O_RDWR|O_CREAT, 0640, $DB_RECNO 
+        or die "Cannot open file 'text': $!\n" ;
+
+    # Add a few key/value pairs to the file
+    $h[0] = "orange" ;
+    $h[1] = "blue" ;
+    $h[2] = "yellow" ;
+
+    push @h, "green", "black" ;
+
+    my $elements = scalar @h ;
+    print "The array contains $elements entries\n" ;
+
+    my $last = pop @h ;
+    print "popped $last\n" ;
+
+    unshift @h, "white" ;
+    my $first = shift @h ;
+    print "shifted $first\n" ;
+
+    # Check for existence of a key
+    print "Element 1 Exists with value $h[1]\n" if $h[1] ;
+
+    # use a negative index
+    print "The last element is $h[-1]\n" ;
+    print "The 2nd last element is $h[-2]\n" ;
+
+    untie @h ;
+
+Here is the output from the script:
+
+    The array contains 5 entries
+    popped black
+    shifted white
+    Element 1 Exists with value blue
+    The last element is green
+    The 2nd last element is yellow
+
+=head2 Extra RECNO Methods
+
+If you are using a version of Perl earlier than 5.004_57, the tied
+array interface is quite limited. In the example script above
+C<push>, C<pop>, C<shift>, C<unshift>
+or determining the array length will not work with a tied array.
+
+To make the interface more useful for older versions of Perl, a number
+of methods are supplied with B<DB_File> to simulate the missing array
+operations. All these methods are accessed via the object returned from
+the tie call.
+
+Here are the methods:
+
+=over 5
+
+=item B<$X-E<gt>push(list) ;>
+
+Pushes the elements of C<list> to the end of the array.
+
+=item B<$value = $X-E<gt>pop ;>
+
+Removes and returns the last element of the array.
+
+=item B<$X-E<gt>shift>
+
+Removes and returns the first element of the array.
+
+=item B<$X-E<gt>unshift(list) ;>
+
+Pushes the elements of C<list> to the start of the array.
+
+=item B<$X-E<gt>length>
+
+Returns the number of elements in the array.
+
+=back
+
+=head2 Another Example
+
+Here is a more complete example that makes use of some of the methods
+described above. It also makes use of the API interface directly (see 
+L<THE API INTERFACE>).
+
+    use warnings ;
+    use strict ;
+    use vars qw(@h $H $file $i) ;
+    use DB_File ;
+    use Fcntl ;
+    
+    $file = "text" ;
+
+    unlink $file ;
+
+    $H = tie @h, "DB_File", $file, O_RDWR|O_CREAT, 0640, $DB_RECNO 
+        or die "Cannot open file $file: $!\n" ;
+    
+    # first create a text file to play with
+    $h[0] = "zero" ;
+    $h[1] = "one" ;
+    $h[2] = "two" ;
+    $h[3] = "three" ;
+    $h[4] = "four" ;
+
+    
+    # Print the records in order.
+    #
+    # The length method is needed here because evaluating a tied
+    # array in a scalar context does not return the number of
+    # elements in the array.  
+
+    print "\nORIGINAL\n" ;
+    foreach $i (0 .. $H->length - 1) {
+        print "$i: $h[$i]\n" ;
+    }
+
+    # use the push & pop methods
+    $a = $H->pop ;
+    $H->push("last") ;
+    print "\nThe last record was [$a]\n" ;
+
+    # and the shift & unshift methods
+    $a = $H->shift ;
+    $H->unshift("first") ;
+    print "The first record was [$a]\n" ;
+
+    # Use the API to add a new record after record 2.
+    $i = 2 ;
+    $H->put($i, "Newbie", R_IAFTER) ;
+
+    # and a new record before record 1.
+    $i = 1 ;
+    $H->put($i, "New One", R_IBEFORE) ;
+
+    # delete record 3
+    $H->del(3) ;
+
+    # now print the records in reverse order
+    print "\nREVERSE\n" ;
+    for ($i = $H->length - 1 ; $i >= 0 ; -- $i)
+      { print "$i: $h[$i]\n" }
+
+    # same again, but use the API functions instead
+    print "\nREVERSE again\n" ;
+    my ($s, $k, $v)  = (0, 0, 0) ;
+    for ($s = $H->seq($k, $v, R_LAST) ; 
+             $s == 0 ; 
+             $s = $H->seq($k, $v, R_PREV))
+      { print "$k: $v\n" }
+
+    undef $H ;
+    untie @h ;
+
+and this is what it outputs:
+
+    ORIGINAL
+    0: zero
+    1: one
+    2: two
+    3: three
+    4: four
+
+    The last record was [four]
+    The first record was [zero]
+
+    REVERSE
+    5: last
+    4: three
+    3: Newbie
+    2: one
+    1: New One
+    0: first
+
+    REVERSE again
+    5: last
+    4: three
+    3: Newbie
+    2: one
+    1: New One
+    0: first
+
+Notes:
+
+=over 5
+
+=item 1.
+
+Rather than iterating through the array, C<@h> like this:
+
+    foreach $i (@h)
+
+it is necessary to use either this:
+
+    foreach $i (0 .. $H->length - 1) 
+
+or this:
+
+    for ($a = $H->get($k, $v, R_FIRST) ;
+         $a == 0 ;
+         $a = $H->get($k, $v, R_NEXT) )
+
+=item 2.
+
+Notice that both times the C<put> method was used the record index was
+specified using a variable, C<$i>, rather than the literal value
+itself. This is because C<put> will return the record number of the
+inserted line via that parameter.
+
+=back
+
+=head1 THE API INTERFACE
+
+As well as accessing Berkeley DB using a tied hash or array, it is also
+possible to make direct use of most of the API functions defined in the
+Berkeley DB documentation.
+
+To do this you need to store a copy of the object returned from the tie.
+
+	$db = tie %hash, "DB_File", "filename" ;
+
+Once you have done that, you can access the Berkeley DB API functions
+as B<DB_File> methods directly like this:
+
+	$db->put($key, $value, R_NOOVERWRITE) ;
+
+B<Important:> If you have saved a copy of the object returned from
+C<tie>, the underlying database file will I<not> be closed until both
+the tied variable is untied and all copies of the saved object are
+destroyed. 
+
+    use DB_File ;
+    $db = tie %hash, "DB_File", "filename" 
+        or die "Cannot tie filename: $!" ;
+    ...
+    undef $db ;
+    untie %hash ;
+
+See L<The untie() Gotcha> for more details.
+
+All the functions defined in L<dbopen> are available except for
+close() and dbopen() itself. The B<DB_File> method interface to the
+supported functions have been implemented to mirror the way Berkeley DB
+works whenever possible. In particular note that:
+
+=over 5
+
+=item *
+
+The methods return a status value. All return 0 on success.
+All return -1 to signify an error and set C<$!> to the exact
+error code. The return code 1 generally (but not always) means that the
+key specified did not exist in the database.
+
+Other return codes are defined. See below and in the Berkeley DB
+documentation for details. The Berkeley DB documentation should be used
+as the definitive source.
+
+=item *
+
+Whenever a Berkeley DB function returns data via one of its parameters,
+the equivalent B<DB_File> method does exactly the same.
+
+=item *
+
+If you are careful, it is possible to mix API calls with the tied
+hash/array interface in the same piece of code. Although only a few of
+the methods used to implement the tied interface currently make use of
+the cursor, you should always assume that the cursor has been changed
+any time the tied hash/array interface is used. As an example, this
+code will probably not do what you expect:
+
+    $X = tie %x, 'DB_File', $filename, O_RDWR|O_CREAT, 0777, $DB_BTREE
+        or die "Cannot tie $filename: $!" ;
+
+    # Get the first key/value pair and set  the cursor
+    $X->seq($key, $value, R_FIRST) ;
+
+    # this line will modify the cursor
+    $count = scalar keys %x ; 
+
+    # Get the second key/value pair.
+    # oops, it didn't, it got the last key/value pair!
+    $X->seq($key, $value, R_NEXT) ;
+
+The code above can be rearranged to get around the problem, like this:
+
+    $X = tie %x, 'DB_File', $filename, O_RDWR|O_CREAT, 0777, $DB_BTREE
+        or die "Cannot tie $filename: $!" ;
+
+    # this line will modify the cursor
+    $count = scalar keys %x ; 
+
+    # Get the first key/value pair and set  the cursor
+    $X->seq($key, $value, R_FIRST) ;
+
+    # Get the second key/value pair.
+    # worked this time.
+    $X->seq($key, $value, R_NEXT) ;
+
+=back
+
+All the constants defined in L<dbopen> for use in the flags parameters
+in the methods defined below are also available. Refer to the Berkeley
+DB documentation for the precise meaning of the flags values.
+
+Below is a list of the methods available.
+
+=over 5
+
+=item B<$status = $X-E<gt>get($key, $value [, $flags]) ;>
+
+Given a key (C<$key>) this method reads the value associated with it
+from the database. The value read from the database is returned in the
+C<$value> parameter.
+
+If the key does not exist the method returns 1.
+
+No flags are currently defined for this method.
+
+=item B<$status = $X-E<gt>put($key, $value [, $flags]) ;>
+
+Stores the key/value pair in the database.
+
+If you use either the R_IAFTER or R_IBEFORE flags, the C<$key> parameter
+will have the record number of the inserted key/value pair set.
+
+Valid flags are R_CURSOR, R_IAFTER, R_IBEFORE, R_NOOVERWRITE and
+R_SETCURSOR.
+
+=item B<$status = $X-E<gt>del($key [, $flags]) ;>
+
+Removes all key/value pairs with key C<$key> from the database.
+
+A return code of 1 means that the requested key was not in the
+database.
+
+R_CURSOR is the only valid flag at present.
+
+=item B<$status = $X-E<gt>fd ;>
+
+Returns the file descriptor for the underlying database.
+
+See L<Locking: The Trouble with fd> for an explanation for why you should
+not use C<fd> to lock your database.
+
+=item B<$status = $X-E<gt>seq($key, $value, $flags) ;>
+
+This interface allows sequential retrieval from the database. See
+L<dbopen> for full details.
+
+Both the C<$key> and C<$value> parameters will be set to the key/value
+pair read from the database.
+
+The flags parameter is mandatory. The valid flag values are R_CURSOR,
+R_FIRST, R_LAST, R_NEXT and R_PREV.
+

+=head1 DBM FILTERS
+
+A DBM Filter is a piece of code that is be used when you I<always>
+want to make the same transformation to all keys and/or values in a
+DBM database.
+
+There are four methods associated with DBM Filters. All work identically,
+and each is used to install (or uninstall) a single DBM Filter. Each
+expects a single parameter, namely a reference to a sub. The only
+difference between them is the place that the filter is installed.
+
+To summarise:
+
+=over 5
+
+=item B<filter_store_key>
+
+If a filter has been installed with this method, it will be invoked
+every time you write a key to a DBM database.
+
+=item B<filter_store_value>
+
+If a filter has been installed with this method, it will be invoked
+every time you write a value to a DBM database.
+
+
+=item B<filter_fetch_key>
+
+If a filter has been installed with this method, it will be invoked
+every time you read a key from a DBM database.
+
+=item B<filter_fetch_value>
+
+If a filter has been installed with this method, it will be invoked
+every time you read a value from a DBM database.
+
+=back
+
+You can use any combination of the methods, from none, to all four.
+
+All filter methods return the existing filter, if present, or C<undef>
+in not.
+
+To delete a filter pass C<undef> to it.
+
+=head2 The Filter
+
+When each filter is called by Perl, a local copy of C<$_> will contain
+the key or value to be filtered. Filtering is achieved by modifying
+the contents of C<$_>. The return code from the filter is ignored.
+
+=head2 An Example -- the NULL termination problem.
+
+Consider the following scenario. You have a DBM database
+that you need to share with a third-party C application. The C application
+assumes that I<all> keys and values are NULL terminated. Unfortunately
+when Perl writes to DBM databases it doesn't use NULL termination, so
+your Perl application will have to manage NULL termination itself. When
+you write to the database you will have to use something like this:
+
+    $hash{"$key\0"} = "$value\0" ;
+
+Similarly the NULL needs to be taken into account when you are considering
+the length of existing keys/values.
+
+It would be much better if you could ignore the NULL terminations issue
+in the main application code and have a mechanism that automatically
+added the terminating NULL to all keys and values whenever you write to
+the database and have them removed when you read from the database. As I'm
+sure you have already guessed, this is a problem that DBM Filters can
+fix very easily.
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+
+    my %hash ;
+    my $filename = "/tmp/filt" ;
+    unlink $filename ;
+
+    my $db = tie %hash, 'DB_File', $filename, O_CREAT|O_RDWR, 0666, $DB_HASH 
+      or die "Cannot open $filename: $!\n" ;
+
+    # Install DBM Filters
+    $db->filter_fetch_key  ( sub { s/\0$//    } ) ;
+    $db->filter_store_key  ( sub { $_ .= "\0" } ) ;
+    $db->filter_fetch_value( sub { s/\0$//    } ) ;
+    $db->filter_store_value( sub { $_ .= "\0" } ) ;
+
+    $hash{"abc"} = "def" ;
+    my $a = $hash{"ABC"} ;
+    # ...
+    undef $db ;
+    untie %hash ;
+
+Hopefully the contents of each of the filters should be
+self-explanatory. Both "fetch" filters remove the terminating NULL,
+and both "store" filters add a terminating NULL.
+
+
+=head2 Another Example -- Key is a C int.
+
+Here is another real-life example. By default, whenever Perl writes to
+a DBM database it always writes the key and value as strings. So when
+you use this:
+
+    $hash{12345} = "soemthing" ;
+
+the key 12345 will get stored in the DBM database as the 5 byte string
+"12345". If you actually want the key to be stored in the DBM database
+as a C int, you will have to use C<pack> when writing, and C<unpack>
+when reading.
+
+Here is a DBM Filter that does it:
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+    my %hash ;
+    my $filename = "/tmp/filt" ;
+    unlink $filename ;
+
+
+    my $db = tie %hash, 'DB_File', $filename, O_CREAT|O_RDWR, 0666, $DB_HASH 
+      or die "Cannot open $filename: $!\n" ;
+
+    $db->filter_fetch_key  ( sub { $_ = unpack("i", $_) } ) ;
+    $db->filter_store_key  ( sub { $_ = pack ("i", $_) } ) ;
+    $hash{123} = "def" ;
+    # ...
+    undef $db ;
+    untie %hash ;
+
+This time only two filters have been used -- we only need to manipulate
+the contents of the key, so it wasn't necessary to install any value
+filters.
+
+=head1 HINTS AND TIPS 
+
+
+=head2 Locking: The Trouble with fd
+
+Until version 1.72 of this module, the recommended technique for locking
+B<DB_File> databases was to flock the filehandle returned from the "fd"
+function. Unfortunately this technique has been shown to be fundamentally
+flawed (Kudos to David Harris for tracking this down). Use it at your own
+peril!
+
+The locking technique went like this. 
+
+    $db = tie(%db, 'DB_File', '/tmp/foo.db', O_CREAT|O_RDWR, 0644)
+        || die "dbcreat /tmp/foo.db $!";
+    $fd = $db->fd;
+    open(DB_FH, "+<&=$fd") || die "dup $!";
+    flock (DB_FH, LOCK_EX) || die "flock: $!";
+    ...
+    $db{"Tom"} = "Jerry" ;
+    ...
+    flock(DB_FH, LOCK_UN);
+    undef $db;
+    untie %db;
+    close(DB_FH);
+
+In simple terms, this is what happens:
+
+=over 5
+
+=item 1.
+
+Use "tie" to open the database.
+
+=item 2.
+

+
+Here is the crux of the problem. A side-effect of opening the B<DB_File>
+database in step 2 is that an initial block from the database will get
+read from disk and cached in memory.
+
+To see why this is a problem, consider what can happen when two processes,
+say "A" and "B", both want to update the same B<DB_File> database
+using the locking steps outlined above. Assume process "A" has already
+opened the database and has a write lock, but it hasn't actually updated
+the database yet (it has finished step 2, but not started step 3 yet). Now
+process "B" tries to open the same database - step 1 will succeed,
+but it will block on step 2 until process "A" releases the lock. The
+important thing to notice here is that at this point in time both
+processes will have cached identical initial blocks from the database.
+
+Now process "A" updates the database and happens to change some of the
+data held in the initial buffer. Process "A" terminates, flushing
+all cached data to disk and releasing the database lock. At this point
+the database on disk will correctly reflect the changes made by process
+"A".
+
+With the lock released, process "B" can now continue. It also updates the
+database and unfortunately it too modifies the data that was in its
+initial buffer. Once that data gets flushed to disk it will overwrite
+some/all of the changes process "A" made to the database.
+
+The result of this scenario is at best a database that doesn't contain
+what you expect. At worst the database will corrupt.
+
+The above won't happen every time competing process update the same
+B<DB_File> database, but it does illustrate why the technique should
+not be used.
+
+=head2 Safe ways to lock a database
+
+Starting with version 2.x, Berkeley DB  has internal support for locking.
+The companion module to this one, B<BerkeleyDB>, provides an interface
+to this locking functionality. If you are serious about locking
+Berkeley DB databases, I strongly recommend using B<BerkeleyDB>.
+
+If using B<BerkeleyDB> isn't an option, there are a number of modules
+available on CPAN that can be used to implement locking. Each one
+implements locking differently and has different goals in mind. It is
+therefore worth knowing the difference, so that you can pick the right
+one for your application. Here are the three locking wrappers:
+
+=over 5
+
+=item B<Tie::DB_Lock>
+
+A B<DB_File> wrapper which creates copies of the database file for
+read access, so that you have a kind of a multiversioning concurrent read
+system. However, updates are still serial. Use for databases where reads
+may be lengthy and consistency problems may occur.
+
+=item B<Tie::DB_LockFile> 
+
+A B<DB_File> wrapper that has the ability to lock and unlock the database
+while it is being used. Avoids the tie-before-flock problem by simply
+re-tie-ing the database when you get or drop a lock.  Because of the
+flexibility in dropping and re-acquiring the lock in the middle of a
+session, this can be massaged into a system that will work with long
+updates and/or reads if the application follows the hints in the POD
+documentation.
+
+=item B<DB_File::Lock> 
+
+An extremely lightweight B<DB_File> wrapper that simply flocks a lockfile
+before tie-ing the database and drops the lock after the untie. Allows
+one to use the same lockfile for multiple databases to avoid deadlock
+problems, if desired. Use for databases where updates are reads are
+quick and simple flock locking semantics are enough.
+
+=back
+
+=head2 Sharing Databases With C Applications
+
+There is no technical reason why a Berkeley DB database cannot be
+shared by both a Perl and a C application.
+
+The vast majority of problems that are reported in this area boil down
+to the fact that C strings are NULL terminated, whilst Perl strings are
+not. See L<DBM FILTERS> for a generic way to work around this problem.
+
+Here is a real example. Netscape 2.0 keeps a record of the locations you
+visit along with the time you last visited them in a DB_HASH database.
+This is usually stored in the file F<~/.netscape/history.db>. The key
+field in the database is the location string and the value field is the
+time the location was last visited stored as a 4 byte binary value.
+
+If you haven't already guessed, the location string is stored with a
+terminating NULL. This means you need to be careful when accessing the
+database.
+
+Here is a snippet of code that is loosely based on Tom Christiansen's
+I<ggh> script (available from your nearest CPAN archive in
+F<authors/id/TOMC/scripts/nshist.gz>).
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+    use Fcntl ;
+
+    use vars qw( $dotdir $HISTORY %hist_db $href $binary_time $date ) ;
+    $dotdir = $ENV{HOME} || $ENV{LOGNAME};
+
+    $HISTORY = "$dotdir/.netscape/history.db";
+
+    tie %hist_db, 'DB_File', $HISTORY
+        or die "Cannot open $HISTORY: $!\n" ;;
+
+    # Dump the complete database
+    while ( ($href, $binary_time) = each %hist_db ) {
+
+        # remove the terminating NULL
+        $href =~ s/\x00$// ;
+
+        # convert the binary time into a user friendly string
+        $date = localtime unpack("V", $binary_time);
+        print "$date $href\n" ;
+    }
+
+    # check for the existence of a specific key
+    # remember to add the NULL
+    if ( $binary_time = $hist_db{"http://mox.perl.com/\x00"} ) {
+        $date = localtime unpack("V", $binary_time) ;
+        print "Last visited mox.perl.com on $date\n" ;
+    }
+    else {
+        print "Never visited mox.perl.com\n"
+    }
+
+    untie %hist_db ;
+
+=head2 The untie() Gotcha
+
+If you make use of the Berkeley DB API, it is I<very> strongly
+recommended that you read L<perltie/The untie Gotcha>. 
+
+Even if you don't currently make use of the API interface, it is still
+worth reading it.
+
+Here is an example which illustrates the problem from a B<DB_File>
+perspective:
+
+    use DB_File ;
+    use Fcntl ;
+
+    my %x ;
+    my $X ;
+
+    $X = tie %x, 'DB_File', 'tst.fil' , O_RDWR|O_TRUNC
+        or die "Cannot tie first time: $!" ;
+
+    $x{123} = 456 ;
+
+    untie %x ;
+
+    tie %x, 'DB_File', 'tst.fil' , O_RDWR|O_CREAT
+        or die "Cannot tie second time: $!" ;
+
+    untie %x ;
+
+When run, the script will produce this error message:
+
+    Cannot tie second time: Invalid argument at bad.file line 14.
+
+Although the error message above refers to the second tie() statement
+in the script, the source of the problem is really with the untie()
+statement that precedes it.
+
+Having read L<perltie> you will probably have already guessed that the
+error is caused by the extra copy of the tied object stored in C<$X>.
+If you haven't, then the problem boils down to the fact that the
+B<DB_File> destructor, DESTROY, will not be called until I<all>
+references to the tied object are destroyed. Both the tied variable,
+C<%x>, and C<$X> above hold a reference to the object. The call to
+untie() will destroy the first, but C<$X> still holds a valid
+reference, so the destructor will not get called and the database file
+F<tst.fil> will remain open. The fact that Berkeley DB then reports the
+attempt to open a database that is already open via the catch-all
+"Invalid argument" doesn't help.
+
+If you run the script with the C<-w> flag the error message becomes:
+
+    untie attempted while 1 inner references still exist at bad.file line 12.
+    Cannot tie second time: Invalid argument at bad.file line 14.
+
+which pinpoints the real problem. Finally the script can now be
+modified to fix the original problem by destroying the API object
+before the untie:
+
+    ...
+    $x{123} = 456 ;
+
+    undef $X ;
+    untie %x ;
+
+    $X = tie %x, 'DB_File', 'tst.fil' , O_RDWR|O_CREAT
+    ...
+
+
+=head1 COMMON QUESTIONS
+
+=head2 Why is there Perl source in my database?
+
+If you look at the contents of a database file created by DB_File,
+there can sometimes be part of a Perl script included in it.
+
+This happens because Berkeley DB uses dynamic memory to allocate
+buffers which will subsequently be written to the database file. Being
+dynamic, the memory could have been used for anything before DB
+malloced it. As Berkeley DB doesn't clear the memory once it has been
+allocated, the unused portions will contain random junk. In the case
+where a Perl script gets written to the database, the random junk will
+correspond to an area of dynamic memory that happened to be used during
+the compilation of the script.
+
+Unless you don't like the possibility of there being part of your Perl
+scripts embedded in a database file, this is nothing to worry about.
+
+=head2 How do I store complex data structures with DB_File?
+
+Although B<DB_File> cannot do this directly, there is a module which
+can layer transparently over B<DB_File> to accomplish this feat.
+
+Check out the MLDBM module, available on CPAN in the directory
+F<modules/by-module/MLDBM>.
+
+=head2 What does "Invalid Argument" mean?
+
+You will get this error message when one of the parameters in the
+C<tie> call is wrong. Unfortunately there are quite a few parameters to
+get wrong, so it can be difficult to figure out which one it is.
+
+Here are a couple of possibilities:
+
+=over 5
+
+=item 1.
+
+Attempting to reopen a database without closing it. 
+
+=item 2.
+
+Using the O_WRONLY flag.
+
+=back
+
+=head2 What does "Bareword 'DB_File' not allowed" mean? 
+
+You will encounter this particular error message when you have the
+C<strict 'subs'> pragma (or the full strict pragma) in your script.
+Consider this script:
+
+    use warnings ;
+    use strict ;
+    use DB_File ;
+    use vars qw(%x) ;
+    tie %x, DB_File, "filename" ;
+
+Running it produces the error in question:
+
+    Bareword "DB_File" not allowed while "strict subs" in use 
+
+To get around the error, place the word C<DB_File> in either single or
+double quotes, like this:
+
+    tie %x, "DB_File", "filename" ;
+
+Although it might seem like a real pain, it is really worth the effort
+of having a C<use strict> in all your scripts.

+
+=head1 BUGS
+
+Some older versions of Berkeley DB had problems with fixed length
+records using the RECNO file format. This problem has been fixed since
+version 1.85 of Berkeley DB.
+
+I am sure there are bugs in the code. If you do find any, or can
+suggest any enhancements, I would welcome your comments.
+
+=head1 AVAILABILITY
+
+B<DB_File> comes with the standard Perl source distribution. Look in
+the directory F<ext/DB_File>. Given the amount of time between releases
+of Perl the version that ships with Perl is quite likely to be out of
+date, so the most recent version can always be found on CPAN (see
+L<perlmod/CPAN> for details), in the directory
+F<modules/by-module/DB_File>.
+
+This version of B<DB_File> will work with either version 1.x, 2.x or
+3.x of Berkeley DB, but is limited to the functionality provided by
+version 1.
+
+The official web site for Berkeley DB is F<http://www.sleepycat.com>.
+All versions of Berkeley DB are available there.
+
+Alternatively, Berkeley DB version 1 is available at your nearest CPAN
+archive in F<src/misc/db.1.85.tar.gz>.
+
+If you are running IRIX, then get Berkeley DB version 1 from
+F<http://reality.sgi.com/ariel>. It has the patches necessary to
+compile properly on IRIX 5.3.

+IMPORTANT NOTICE
+================
+
+If are using the locking technique described in older versions of
+DB_File, please read the section called "Locking: The Trouble with fd"
+in DB_File.pm immediately. The locking method has been found to be
+unsafe. You risk corrupting your data if you continue to use it.
+
+DESCRIPTION
+-----------
+
+DB_File is a module which allows Perl programs to make use of the
+facilities provided by Berkeley DB version 1. (DB_File can be built
+version 2 or 3 of Berkeley DB, but it will only support the 1.x
+features),
+
+If you want to make use of the new features available in Berkeley DB
+2.x or 3.x, use the Perl module BerkeleyDB instead.
+
+Berkeley DB is a C library which provides a consistent interface to a
+number of database formats. DB_File provides an interface to all three
+of the database types (hash, btree and recno) currently supported by
+Berkeley DB.
+
+For further details see the documentation included at the end of the
+file DB_File.pm.
+
+PREREQUISITES
+-------------
+
+Before you can build DB_File you must have the following installed on
+your system:
+
+    * Perl 5.004 or greater.
+
+    * Berkeley DB.
+
+      The official web site for Berkeley DB is http://www.sleepycat.com.
+      The latest version of Berkeley DB is always available there. It
+      is recommended that you use the most recent version available at
+      the Sleepycat site.
+
+      The one exception to this advice is where you want to use DB_File
+      to access database files created by a third-party application, like
+      Sendmail or Netscape. In these cases you must build DB_File with a
+      compatible version of Berkeley DB.
+
+      If you want to use Berkeley DB 2.x, you must have version 2.3.4
+      or greater.  If you want to use Berkeley DB 3.x, any version will
+      do. For Berkeley DB 1.x, use either version 1.85 or 1.86.
+
+
+BUILDING THE MODULE
+-------------------
+
+Assuming you have met all the prerequisites, building the module should
+be relatively straightforward.
+
+Step 1 : If you are running either Solaris 2.5 or HP-UX 10 and want
+         to use Berkeley DB version 2 or 3, read either the Solaris Notes
+         or HP-UX Notes sections below.  If you are running Linux please
+         read the Linux Notes section before proceeding.
+
+Step 2 : Edit the file config.in to suit you local installation.
+         Instructions are given in the file.
+
+Step 3 : Build and test the module using this sequence of commands:
+
+             perl Makefile.PL
+             make
+             make test
+
+
+  NOTE:
+      If you have a very old version of Berkeley DB (i.e. pre 1.85),
+      three of the tests in the recno test harness may fail (tests 51,
+      53 and 55). You can safely ignore the errors if you're never
+      going to use the broken functionality (recno databases with a
+      modified bval).  Otherwise you'll have to upgrade your DB
+      library.
+
+
+INSTALLATION
+------------
+
+    make install
+
+
+TROUBLESHOOTING
+===============
+
+Here are some of the common problems people encounter when building
+DB_File.
+
+Missing db.h or libdb.a
+-----------------------
+
+If you get an error like this:
+
+  cc -c -I/usr/local/include -Dbool=char -DHAS_BOOL
+  -O2    -DVERSION=\"1.64\" -DXS_VERSION=\"1.64\" -fpic
+  -I/usr/local/lib/perl5/i586-linux/5.00404/CORE -DmDB_Prefix_t=size_t
+  -DmDB_Hash_t=u_int32_t DB_File.c
+  DB_File.xs:101: db.h: No such file or directory
+
+or this:
+
+  LD_RUN_PATH="/lib" cc -o blib/arch/auto/DB_File/DB_File.so  -shared
+  -L/usr/local/lib DB_File.o    -L/usr/local/lib -ldb
+  ld: cannot open -ldb: No such file or directory
+
+This symptom can imply:
+
+ 1. You don't have Berkeley DB installed on your system at all.
+    Solution: get & install Berkeley DB.
+
+ 2. You do have Berkeley DB installed, but it isn't in a standard place.
+    Solution: Edit config.in and set the LIB and INCLUDE variables to point
+              to the directories where libdb.a and db.h are installed.
+
+
+Undefined symbol db_version
+---------------------------
+
+DB_File seems to have built correctly, but you get an error like this
+when you run the test harness:
+
+  $ make test
+  PERL_DL_NONLAZY=1 /usr/bin/perl5.00404 -I./blib/arch -I./blib/lib
+  -I/usr/local/lib/perl5/i586-linux/5.00404 -I/usr/local/lib/perl5 -e 'use
+  Test::Harness qw(&runtests $verbose); $verbose=0; runtests @ARGV;' t/*.t
+  t/db-btree..........Can't load './blib/arch/auto/DB_File/DB_File.so' for
+  module DB_File: ./blib/arch/auto/DB_File/DB_File.so: undefined symbol:
+  db_version at /usr/local/lib/perl5/i586-linux/5.00404/DynaLoader.pm
+  line 166.
+
+  at t/db-btree.t line 21
+  BEGIN failed--compilation aborted at t/db-btree.t line 21.
+  dubious Test returned status 2 (wstat 512, 0x200)
+
+This error usually happens when you have both version 1 and version
+2 of Berkeley DB installed on your system and DB_File attempts to
+build using the db.h for Berkeley DB version 2 and the version 1
+library. Unfortunately the two versions aren't compatible with each
+other. The undefined symbol error is actually caused because Berkeley
+DB version 1 doesn't have the symbol db_version.
+
+Solution: Setting the LIB & INCLUDE variables in config.in to point to the
+          correct directories can sometimes be enough to fix this
+          problem. If that doesn't work the easiest way to fix the
+          problem is to either delete or temporarily rename the copies
+          of db.h and libdb.a that you don't want DB_File to use.
+
+Incompatible versions of db.h and libdb
+---------------------------------------
+
+BerkeleyDB seems to have built correctly, but you get an error like this
+when you run the test harness:
+
+  $ make test
+  PERL_DL_NONLAZY=1 /home/paul/perl/install/bin/perl5.00560 -Iblib/arch
+  -Iblib/lib -I/home/paul/perl/install/5.005_60/lib/5.00560/i586-linux
+  -I/home/paul/perl/install/5.005_60/lib/5.00560 -e 'use Test::Harness
+  qw(&runtests $verbose); $verbose=0; runtests @ARGV;' t/*.t
+  t/db-btree..........
+  DB_File needs compatible versions of libdb & db.h
+          you have db.h version 2.3.7 and libdb version 2.7.5
+  BEGIN failed--compilation aborted at t/db-btree.t line 21.
+  ...
+
+Another variation on the theme of having two versions of Berkeley DB on
+your system.
+
+Solution: Setting the LIB & INCLUDE variables in config.in to point to the
+          correct directories can sometimes be enough to fix this
+          problem. If that doesn't work the easiest way to fix the
+          problem is to either delete or temporarily rename the copies
+          of db.h and libdb.a that you don't want BerkeleyDB to use.
+          If you are running Linux, please read the Linux Notes section
+          below.
+
+
+Linux Notes
+-----------
+
+Newer versions of Linux (e.g. RedHat 6, SuSe 6) ship with a C library
+that has version 2.x of Berkeley DB linked into it. This makes it
+difficult to build this module with anything other than the version of
+Berkeley DB that shipped with your Linux release. If you do try to use
+a different version of Berkeley DB you will most likely get the error
+described in the "Incompatible versions of db.h and libdb" section of
+this file.
+
+To make matters worse, prior to Perl 5.6.1, the perl binary itself
+*always* included the Berkeley DB library.
+
+If you want to use a newer version of Berkeley DB with this module, the
+easiest solution is to use Perl 5.6.1 (or better) and Berkeley DB 3.x
+(or better).
+
+There are two approaches you can use to get older versions of Perl to
+work with specific versions of Berkeley DB. Both have their advantages
+and disadvantages.
+
+The first approach will only work when you want to build a version of
+Perl older than 5.6.1 along with Berkeley DB 3.x. If you want to use
+Berkeley DB 2.x, you must use the next approach. This approach involves
+rebuilding your existing version of Perl after applying an unofficial
+patch. The "patches" directory in the this module's source distribution
+contains a number of patch files. There is one patch file for every
+stable version of Perl since 5.004. Apply the appropriate patch to your
+Perl source tree before re-building and installing Perl from scratch.
+For example, assuming you are in the top-level source directory for
+Perl 5.6.0, the command below will apply the necessary patch. Remember
+to replace the path shown below with one that points to this module's
+patches directory.
+
+    patch -p1 -N </path/to/DB_File/patches/5.6.0
+
+Now rebuild & install perl. You should now have a perl binary that can
+be used to build this module. Follow the instructions in "BUILDING THE
+MODULE", remembering to set the INCLUDE and LIB variables in config.in.
+
+
+The second approach will work with both Berkeley DB 2.x and 3.x.
+Start by building Berkeley DB as a shared library. This is from
+the Berkeley DB build instructions:
+
+    Building Shared Libraries for the GNU GCC compiler
+
+    If you're using gcc and there's no better shared library example for
+    your architecture, the following shared library build procedure will
+    probably work.
+
+    Add the -fpic option to the CFLAGS value in the Makefile.
+
+    Rebuild all of your .o files. This will create a Berkeley DB library
+    that contains .o files with PIC code. To build the shared library,
+    then take the following steps in the library build directory:
+
+    % mkdir tmp
+    % cd tmp
+    % ar xv ../libdb.a
+    % gcc -shared -o libdb.so *.o
+    % mv libdb.so ..
+    % cd ..
+    % rm -rf tmp
+
+    Note, you may have to change the gcc line depending on the
+    requirements of your system.
+
+    The file libdb.so is your shared library
+
+Once you have built libdb.so, you will need to store it somewhere safe.
+
+    cp libdb.so /usr/local/BerkeleyDB/lib
+
+If you now set the LD_PRELOAD environment variable to point to this
+shared library, Perl will use it instead of the version of Berkeley DB
+that shipped with your Linux distribution.
+
+    export LD_PRELOAD=/usr/local/BerkeleyDB/lib/libdb.so
+
+Finally follow the instructions in "BUILDING THE MODULE" to build,
+test and install this module. Don't forget to set the INCLUDE and LIB
+variables in config.in.
+
+Remember, you will need to have the LD_PRELOAD variable set anytime you
+want to use Perl with Berkeley DB. Also note that if you have LD_PRELOAD
+permanently set it will affect ALL commands you execute. This may be a
+problem if you run any commands that access a database created by the
+version of Berkeley DB that shipped with your Linux distribution.
+
+
+Solaris Notes
+-------------
+
+If you are running Solaris 2.5, and you get this error when you run the
+DB_File test harness:
+
+    libc internal error: _rmutex_unlock: rmutex not held.
+
+you probably need to install a Sun patch. It has been reported that
+Sun patch 103187-25 (or later revisions) fixes this problem.
+
+To find out if you have the patch installed, the command "showrev -p"
+will display the patches that are currently installed on your system.
+
+
+HP-UX Notes
+-----------
+
+Some people running HP-UX 10 have reported getting an error like this
+when building DB_File with the native HP-UX compiler.
+
+    ld: (Warning) At least one PA 2.0 object file (DB_File.o) was detected.
+    The linked output may not run on a PA 1.x system.
+    ld: Invalid loader fixup for symbol "$000000A5".
+
+If this is the case for you, Berkeley DB needs to be recompiled with
+the +z or +Z option and the resulting library placed in a .sl file. The
+following steps should do the trick:
+
+  1: Configure the Berkeley DB distribution with the +z or +Z C compiler
+     flag:
+
+        env "CFLAGS=+z" ../dist/configure ...
+
+  2: Edit the Berkeley DB Makefile and change:
+
+        "libdb= libdb.a" to "libdb= libdb.sl".
+
+
+  3: Build and install the Berkeley DB distribution as usual.
+
+
+IRIX NOTES
+----------
+
+If you are running IRIX, and want to use Berkeley DB version 1, you can
+get it from http://reality.sgi.com/ariel. It has the patches necessary
+to compile properly on IRIX 5.3.
+
+
+FEEDBACK
+========
+
+How to report a problem with DB_File.
+
+To help me help you, I need the following information:
+
+ 1. The version of Perl and the operating system name and version you
+    are running. The *complete* output from running "perl -V" will
+    tell me all I need to know. Don't edit the output in any way. Note,
+    I want you to run "perl -V" and NOT "perl -v".
+
+    If your perl does not understand the "-V" option it is too old. DB_File
+    needs Perl version 5.004 or better.
+
+ 2. The version of DB_File you have.
+    If you have successfully installed DB_File, this one-liner will
+    tell you:
+
+       perl -e 'use DB_File; print "DB_File ver $DB_File::VERSION\n"'
+
+    If you haven't installed DB_File then search DB_File.pm for a line
+    like this:
+
+      $VERSION = "1.20" ;
+
+ 3. The version of Berkeley DB you are using.
+    If you are using a version older than 1.85, think about upgrading. One
+    point to note if you are considering upgrading Berkeley DB - the
+    file formats for 1.85, 1.86, 2.0, 3.0 & 3.1 are all different.
+
+    If you have successfully installed DB_File, this command will display
+    the version of Berkeley DB it was built with:
+
+       perl -e 'use DB_File; print "Berkeley DB ver $DB_File::db_ver\n"'
+
+ 4. If you are having problems building DB_File, send me a complete log
+    of what happened.
+
+ 5. Now the difficult one. If you think you have found a bug in DB_File
+    and you want me to fix it, you will *greatly* enhance the chances
+    of me being able to track it down by sending me a small
+    self-contained Perl script that illustrates the problem you are
+    encountering. Include a summary of what you think the problem is
+    and a log of what happens when you run the script, in case I can't
+    reproduce your problem on my system. If possible, don't have the
+    script dependent on an existing 20Meg database. If the script you
+    send me can create the database itself then that is preferred.
+
+    I realise that in some cases this is easier said than done, so if
+    you can only reproduce the problem in your existing script, then
+    you can post me that if you want. Just don't expect me to find your
+    problem in a hurry, or at all. :-)

+# 4. Is the library called libdb?
+#
+#    If you have copies of both 1.x and 2.x Berkeley DB installed on
+#    your system it can sometimes be tricky to make sure you are using
+#    the correct one. Renaming one (or creating a symbolic link) to
+#    include the version number of the library can help.
+#
+#    For example, if you have both Berkeley DB 2.3.12 and 1.85 on your
+#    system and you want to use the Berkeley DB version 2 library you
+#    could rename the version 2 library from libdb.a to libdb-2.3.12.a and
+#    change the DBNAME line below to look like this:
+#
+#        DBNAME = -ldb-2.3.12
+#
+#    That will ensure you are linking the correct version of the DB
+#    library.
+#
+#    Note: If you are building this module with Win32, -llibdb will be
+#    used by default.
+#
+#    If you have changed the name of the library, uncomment the line
+#    below (by removing the leading #) and edit the line to use the name
+#    you have picked.
+ 
+#DBNAME = -ldb-2.4.10
+
+# end of file config.in

+Client/Server Interface for Berkeley DB</H1></CENTER>
+
+<CENTER><I>Susan LoVerso</I>
+<BR><I>sue@sleepycat.com</I>
+<BR><I>Rev 1.3</I>
+<BR><I>1999 Nov 29</I></CENTER>
+
+<P>We provide an interface allowing client/server access to Berkeley DB.&nbsp;&nbsp;
+Our goal is to provide a client and server library to allow users to separate
+the functionality of their applications yet still have access to the full
+benefits of Berkeley DB.&nbsp; The goal is to provide a totally seamless
+interface with minimal modification to existing applications as well.
+<P>The client/server interface for Berkeley DB can be broken up into several
+layers.&nbsp; At the lowest level there is the transport mechanism to send
+out the messages over the network.&nbsp; Above that layer is the messaging
+layer to interpret what comes over the wire, and bundle/unbundle message
+contents.&nbsp; The next layer is Berkeley DB itself.
+<P>The transport layer uses ONC RPC (RFC 1831) and XDR (RFC 1832).&nbsp;
+We declare our message types and operations supported by our program and
+the RPC library and utilities pretty much take care of the rest.&nbsp;
+The
+<I>rpcgen</I> program generates all of the low level code needed.&nbsp;
+We need to define both sides of the RPC.
+<BR>&nbsp;
+<H2>
+<A NAME="DB Modifications"></A>DB Modifications</H2>
+To achieve the goal of a seamless interface, it is necessary to impose
+a constraint on the application. That constraint is simply that all database
+access must be done through an open environment.&nbsp; I.e. this model
+does not support standalone databases.&nbsp; The reason for this constraint
+is so that we have an environment structure internally to store our connection
+to the server.&nbsp; Imposing this constraint means that we can provide
+the seamless interface just by adding a single environment method: <A HREF="../docs/api_c/env_set_server.html">DBENV->set_server()</A>.
+<P>The planned interface for this method is:
+<PRE>DBENV->set_server(dbenv,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* DB_ENV structure */
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hostname&nbsp;&nbsp;&nbsp; /* Host of server */
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cl_timeout, /* Client timeout (sec) */
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; srv_timeout,/* Server timeout (sec) */
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; flags);&nbsp;&nbsp;&nbsp;&nbsp; /* Flags: unused */</PRE>
+This new method takes the hostname of the server, establishes our connection
+and an environment on the server.&nbsp; If a server timeout is specified,
+then we send that to the server as well (and the server may or may not
+choose to use that value).&nbsp; This timeout is how long the server will
+allow the environment to remain idle before declaring it dead and releasing
+resources on the server.&nbsp; The pointer to the connection is stored
+on the client in the DBENV structure and is used by all other methods to
+figure out with whom to communicate.&nbsp; If a client timeout is specified,
+it indicates how long the client is willing to wait for a reply from the
+server.&nbsp; If the values are 0, then defaults are used.&nbsp; Flags
+is currently unused, but exists because we always need to have a placeholder
+for flags and it would be used for specifying authentication desired (were
+we to provide an authentication scheme at some point) or other uses not
+thought of yet!
+<P>This client code is part of the monolithic DB library.&nbsp; The user
+accesses the client functions via a new flag to <A HREF="../docs/api_c/db_env_create.html">db_env_create()</A>.&nbsp;
+That flag is DB_CLIENT.&nbsp; By using this flag the user indicates they
+want to have the client methods rather than the standard methods for the
+environment.&nbsp; Also by issuing this flag, the user needs to connect
+to the server via the <A HREF="../docs/api_c/env_set_server.html">DBENV->set_server()</A>
+method.
+<P>We need two new fields in the <I>DB_ENV </I>structure.&nbsp; One is
+the socket descriptor to communicate to the server, the other field is
+the client identifier the server gives to us.&nbsp; The <I>DB, </I>and<I>
+DBC </I>only need one additional field, the client identifier.&nbsp; The
+<I>DB_TXN</I>
+structure does not need modification, we are overloading the <I>txn_id
+</I>field.
+<H2>
+Issues</H2>
+We need to figure out what to do in case of client and server crashes.&nbsp;
+Both the client library and the server program are stateful.&nbsp; They
+both consume local resources during the lifetime of the connection.&nbsp;
+Should one end drop that connection, the other side needs to release those
+resources.
+<P>If the server crashes, then the client will get an error back.&nbsp;
+I have chosen to implement time-outs on the client side, using a default
+or allowing the application to specify one through the <A HREF="../docs/api_c/env_set_server.html">DBENV->set_server()</A>
+method.&nbsp; Either the current operation will time-out waiting for the
+reply or the next operation called will time out (or get back some other
+kind of error regarding the server's non-existence).&nbsp; In any case,
+if the client application gets back such an error, it should abort any
+open transactions locally, close any databases, and close its environment.&nbsp;
+It may then decide to retry to connect to the server periodically or whenever
+it comes back.&nbsp; If the last operation a client did was a transaction
+commit that did not return or timed out from the server, the client cannot
+determine if the transaction was committed or not but must release the
+local transaction resources. Once the server is back up, recovery must
+be run on the server.&nbsp;&nbsp; If the transaction commit completed on
+the server before the crash, then the operation is redone, if the transaction
+commit did not get to the server, the pieces of the transaction are undone
+on recover.&nbsp; The client can then re-establish its connection and begin
+again.&nbsp; This is effectively like beginning over.&nbsp; The client
+cannot use ID's from its previous connection to the server.&nbsp; However,
+if recovery is run, then consistency is assured.
+<P>If the client crashes, the server needs to somehow figure this out.&nbsp;
+The server is just sitting there waiting for a request to come in.&nbsp;
+A server must be able to time-out a client.&nbsp; Similar to ftpd, if a
+connection is idle for N seconds, then the server decides the client is
+dead and releases that client's resources, aborting any open transactions,
+closing any open databases and environments.&nbsp;&nbsp; The server timing
+out a client is not a trivial issue however.&nbsp; The generated function
+for the server just calls <I>svc_run()</I>.&nbsp; The server code I write
+contains procedures to do specific things.&nbsp; We do not have access
+to the code calling <I>select()</I>.&nbsp; Timing out the select is not
+good enough even if we could do so.&nbsp; We want to time-out idle environments,
+not simply cause a time-out if the server is idle a while.&nbsp; See the
+discussion of the <A HREF="#The Server Program">server program</A> for
+a description of how we accomplish this.
+<P>Since rpcgen generates the main() function of the server, I do not yet
+know how we are going to have the server multi-threaded or multi-process
+without changing the generated code.&nbsp; The RPC book indicates that
+the only way to accomplish this is through modifying the generated code
+in the server.&nbsp; <B>For the moment we will ignore this issue while
+we get the core server working, as it is only a performance issue.</B>
+<P>We do not do any security or authentication.&nbsp; Someone could get
+the code and modify it to spoof messages, trick the server, etc.&nbsp;
+RPC has some amount of authentication built into it.&nbsp; I haven't yet
+looked into it much to know if we want to use it or just point a user at
+it.&nbsp; The changes to the client code are fairly minor, the changes
+to our server procs are fairly minor.&nbsp; We would have to add code to
+a <I>sed</I> script or <I>awk</I> script to change the generated server
+code (yet again) in the dispatch routine to perform authentication.
+<P>We will need to get an official program number from Sun.&nbsp; We can
+get this by sending mail to <I>rpc@sun.com</I> and presumably at some point
+they will send us back a program number that we will encode into our XDR
+description file.&nbsp; Until we release this we can use a program number
+in the "user defined" number space.
+<BR>&nbsp;
+<H2>
+<A NAME="The Server Program"></A>The Server Program</H2>
+The server is a standalone program that the user builds and runs, probably
+as a daemon like process.&nbsp; This program is linked against the Berkeley
+DB library and the RPC library (which is part of the C library on my FreeBSD
+machine, others may have/need <I>-lrpclib</I>).&nbsp; The server basically
+is a slave to the client process.&nbsp; All messages from the client are
+synchronous and two-way.&nbsp; The server handles messages one at a time,
+and sends a reply back before getting another message.&nbsp; There are
+no asynchronous messages generated by the server to the client.
+<P>We have made a choice to modify the generated code for the server.&nbsp;
+The changes will be minimal, generally calling functions we write, that
+are in other source files.&nbsp; The first change is adding a call to our
+time-out function as described below.&nbsp; The second change is changing
+the name of the generated <I>main()</I> function to <I>__dbsrv_main()</I>,
+and adding our own <I>main()</I> function so that we can parse options,
+and set up other initialization we require.&nbsp; I have a <I>sed</I> script
+that is run from the distribution scripts that massages the generated code
+to make these minor changes.
+<P>Primarily the code needed for the server is the collection of the specified
+RPC functions.&nbsp; Each function receives the structure indicated, and
+our code takes out what it needs and passes the information into DB itself.&nbsp;
+The server needs to maintain a translation table for identifiers that we
+pass back to the client for the environment, transaction and database handles.
+<P>The table that the server maintains, assuming one client per server
+process/thread, should contain the handle to the environment, database
+or transaction, a link to maintain parent/child relationships between transactions,
+or databases and cursors, this handle's identifier, a type so that we can
+error if the client passes us a bad id for this call, and a link to this
+handle's environment entry (for time out/activity purposes).&nbsp; The
+table contains, in entries used by environments, a time-out value and an
+activity time stamp.&nbsp; Its use is described below for timing out idle
+clients.
+<P>Here is how we time out clients in the server.&nbsp; We have to modify
+the generated server code, but only to add one line during the dispatch
+function to run the time-out function.&nbsp; The call is made right before
+the return of the dispatch function, after the reply is sent to the client,
+so that client's aren't kept waiting for server bookkeeping activities.&nbsp;
+This time-out function then runs every time the server processes a request.&nbsp;
+In the time-out function we maintain a time-out hint that is the youngest
+environment to time-out.&nbsp; If the current time is less than the hint
+we know we do not need to run through the list of open handles.&nbsp; If
+the hint is expired, then we go through the list of open environment handles,
+and if they are past their expiration, then we close them and clean up.&nbsp;
+If they are not, we set up the hint for the next time.
+<P>Each entry in the open handle table has a pointer back to its environment's
+entry.&nbsp; Every operation within this environment can then update the
+single environment activity record.&nbsp; Every environment can have a
+different time-out.&nbsp; The <A HREF="../docs/api_c/env_set_server.html">DBENV->set_server
+</A>call
+takes a server time-out value.&nbsp; If this value is 0 then a default
+(currently 5 minutes) is used.&nbsp; This time-out value is only a hint
+to the server.&nbsp; It may choose to disregard this value or set the time-out
+based on its own implementation.
+<P>For completeness, the flaws of this time-out implementation should be
+pointed out.&nbsp; First, it is possible that a client could crash with
+open handles, and no other requests come in to the server.&nbsp; Therefore
+the time-out function never gets run and those resources are not released
+(until a request does come in).&nbsp; Similarly, this time-out is not exact.&nbsp;
+The time-out function uses its hint and if it computes a hint on one run,
+an earlier time-out might be created before that time-out expires.&nbsp;
+This issue simply yields a handle that doesn't get released until that
+original hint expires.&nbsp; To illustrate, consider that at the time that
+the time-out function is run, the youngest time-out is 5 minutes in the
+future.&nbsp; Soon after, a new environment is opened that has a time-out
+of 1 minute.&nbsp; If this environment becomes idle (and other operations
+are going on), the time-out function will not release that environment
+until the original 5 minute hint expires.&nbsp; This is not a problem since
+the resources will eventually be released.
+<P>On a similar note, if a client crashes during an RPC, our reply generates
+a SIGPIPE, and our server crashes unless we catch it.&nbsp; Using <I>signal(SIGPIPE,
+SIG_IGN) </I>we can ignore it, and the server will go on.&nbsp; This is
+a call&nbsp; in our <I>main()</I> function that we write.&nbsp; Eventually
+this client's handles would be timed out as described above.&nbsp; We need
+this only for the unfortunate window of a client crashing during the RPC.
+<P>The options below are primarily for control of the program itself,.&nbsp;
+Details relating to databases and environments should be passed from the
+client to the server, since the server can serve many clients, many environments
+and many databases.&nbsp; Therefore it makes more sense for the client
+to set the cache size of its own environment, rather than setting a default
+cachesize on the server that applies as a blanket to any environment it
+may be called upon to open.&nbsp; Options are:
+<UL>
+<LI>
+<B>-t&nbsp;</B> to set the default time-out given to an environment.</LI>
+
+<LI>
+<B>-T</B> to set the maximum time-out allowed for the server.</LI>
+
+<LI>
+<B>-L</B> to log the execution of the server process to a specified file.</LI>
+
+<LI>
+<B>-v</B> to run in verbose mode.</LI>
+
+<LI>
+<B>-M</B>&nbsp; to specify the maximum number of outstanding child server
+processes/threads we can have at any given time.&nbsp; The default is 10.
+<B>[We
+are not yet doing multiple threads/processes.]</B></LI>
+</UL>
+
+<H2>
+The Client Code</H2>
+The client code contains all of the supported functions and methods used
+in this model.&nbsp; There are several methods in the <I>__db_env
+</I>and
+<I>__db</I>
+structures that currently do not apply, such as the callbacks.&nbsp; Those
+fields that are not applicable to the client model point to NULL to notify
+the user of their error.&nbsp; Some method functions remain unchanged,
+as well such as the error calls.
+<P>The client code contains each method function that goes along with the
+<A HREF="#Remote Procedure Calls">RPC
+calls</A> described elsewhere.&nbsp; The client library also contains its
+own version of <A HREF="../docs/api_c/env_create.html">db_env_create()</A>,
+which does not result in any messages going over to the server (since we
+do not yet know what server we are talking to).&nbsp; This function sets
+up the pointers to the correct client functions.
+<P>All of the method functions that handle the messaging have a basic flow
+similar to this:
+<UL>
+<LI>
+Local arg parsing that may be needed</LI>
+
+<LI>
+Marshalling the message header and the arguments we need to send to the
+server</LI>
+
+<LI>
+Sending the message</LI>
+
+<LI>
+Receiving a reply</LI>
+
+<LI>
+Unmarshalling the reply</LI>
+
+<LI>
+Local results processing that may be needed</LI>
+</UL>
+
+<H2>
+Generated Code</H2>
+Almost all of the code is generated from a source file describing the interface
+and an <I>awk</I> script.&nbsp;&nbsp; This awk script generates six (6)
+files for us.&nbsp; It also modifies one.&nbsp; The files are:
+<OL>
+<LI>
+Client file - The C source file created containing the client code.</LI>
+
+<LI>
+Client template file - The C template source file created containing interfaces
+for handling client-local issues such as resource allocation, but with
+a consistent interface with the client code generated.</LI>
+
+<LI>
+Server file - The C source file created containing the server code.</LI>
+
+<LI>
+Server template file - The C template source file created containing interfaces
+for handling server-local issues such as resource allocation, calling into
+the DB library but with a consistent interface with the server code generated.</LI>
+
+<LI>
+XDR file - The XDR message description file created.</LI>
+
+<LI>
+Server sed file - A sed script that contains commands to apply to the server
+procedure file (i.e. the real source file that the server template file
+becomes) so that minor interface changes can be consistently and easily
+applied to the real code.</LI>
+
+<LI>
+Server procedure file - This is the file that is modified by the sed script
+generated.&nbsp; It originated from the server template file.</LI>
+</OL>
+The awk script reads a source file, <I>db_server/rpc.src </I>that describes
+each operation and what sorts of arguments it takes and what it returns
+from the server.&nbsp; The syntax of the source file describes the interface
+to that operation.&nbsp; There are four (4) parts to the syntax:
+<OL>
+<LI>
+<B>BEGIN</B> <B><I>function version# codetype</I></B> - begins a new functional
+interface for the given <B><I>function</I></B>.&nbsp; Each function has
+a <B><I>version number</I></B>, currently all of them are at version number
+one (1).&nbsp; The <B><I>code type</I></B> indicates to the awk script
+what kind of code to generate.&nbsp; The choices are:</LI>
+
+<UL>
+<LI>
+<B>CODE </B>- Generate all code, and return a status value.&nbsp; If specified,
+the client code will simply return the status to the user upon completion
+of the RPC call.</LI>
+
+<LI>
+<B>RETCODE </B>- Generate all code and call a return function in the client
+template file to deal with client issues or with other returned items.&nbsp;
+If specified, the client code generated will call a function of the form
+<I>__dbcl_&lt;name>_ret()
+</I>where
+&lt;name> is replaced with the function name given here.&nbsp; This function
+is placed in the template file because this indicates that something special
+must occur on return.&nbsp; The arguments to this function are the same
+as those for the client function, with the addition of the reply message
+structure.</LI>
+
+<LI>
+<B>NOCLNTCODE - </B>Generate XDR and server code, but no corresponding
+client code. (This is used for functions that are not named the same thing
+on both sides.&nbsp; The only use of this at the moment is db_env_create
+and db_create.&nbsp; The environment create call to the server is actually
+called from the <A HREF="../docs/api_c/env_set_server.html">DBENV->set_server()</A>
+method.&nbsp; The db_create code exists elsewhere in the library and we
+modify that code for the client call.)</LI>
+</UL>
+
+<LI>
+<B>ARG <I>RPC-type C-type varname [list-type]</I></B>- each line of this
+describes an argument to the function.&nbsp; The argument is called <B><I>varname</I></B>.&nbsp;
+The <B><I>C-type</I></B> given is what it should look like in the C code
+generated, such as <B>DB *, u_int32_t, const char *</B>.&nbsp; The
+<B><I>RPC-type</I></B>
+is an indication about how the RPC request message should be constructed.&nbsp;
+The RPC-types allowed are described below.</LI>
+
+<LI>
+<B>RET <I>RPC-type C-type varname [list-type]</I></B>- each line of this
+describes what the server should return from this procedure call (in addition
+to a status, which is always returned and should not be specified).&nbsp;
+The argument is called <B><I>varname</I></B>.&nbsp; The <B><I>C-type</I></B>
+given is what it should look like in the C code generated, such as <B>DB
+*, u_int32_t, const char *</B>.&nbsp; The <B><I>RPC-type</I></B> is an
+indication about how the RPC reply message should be constructed.&nbsp;
+The RPC-types are described below.</LI>
+
+<LI>
+<B>END </B>- End the description of this function.&nbsp; The result is
+that when the awk script encounters the <B>END</B> tag, it now has all
+the information it needs to construct the generated code for this function.</LI>
+</OL>
+The <B><I>RPC-type</I></B> must be one of the following:
+<UL>
+<LI>
+<B>IGNORE </B>- This argument is not passed to the server and should be
+ignored when constructing the XDR code.&nbsp; <B>Only allowed for an ARG
+specfication.</B></LI>
+
+<LI>
+<B>STRING</B> - This argument is a string.</LI>
+
+<LI>
+<B>INT </B>- This argument is an integer of some sort.</LI>
+
+<LI>
+<B>DBT </B>- This argument is a DBT, resulting in its decomposition into
+the request message.</LI>
+
+<LI>
+<B>LIST</B> - This argument is an opaque list passed to the server (NULL-terminated).&nbsp;
+If an argument of this type is given, it must have a <B><I>list-type</I></B>
+specified that is one of:</LI>
+
+<UL>
+<LI>
+<B>STRING</B></LI>
+
+<LI>
+<B>INT</B></LI>
+
+<LI>
+<B>ID</B>.</LI>
+</UL>
+
+<LI>
+<B>ID</B> - This argument is an identifier.</LI>
+</UL>
+So, for example, the source for the DB->join RPC call looks like:
+<PRE>BEGIN&nbsp;&nbsp; dbjoin&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; RETCODE
+ARG&nbsp;&nbsp;&nbsp;&nbsp; ID&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DB *&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; dbp&nbsp;
+ARG&nbsp;&nbsp;&nbsp;&nbsp; LIST&nbsp;&nbsp;&nbsp; DBC **&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; curs&nbsp;&nbsp;&nbsp; ID
+ARG&nbsp;&nbsp;&nbsp;&nbsp; IGNORE&nbsp; DBC **&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; dbcpp&nbsp;
+ARG&nbsp;&nbsp;&nbsp;&nbsp; INT&nbsp;&nbsp;&nbsp;&nbsp; u_int32_t&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; flags
+RET&nbsp;&nbsp;&nbsp;&nbsp; ID&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; long&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; dbcid
+END</PRE>
+Our first line tells us we are writing the dbjoin function.&nbsp; It requires
+special code on the client so we indicate that with the RETCODE.&nbsp;
+This method takes four arguments.&nbsp; For the RPC request we need the
+database ID from the dbp, we construct a NULL-terminated list of IDs for
+the cursor list, we ignore the argument to return the cursor handle to
+the user, and we pass along the flags.&nbsp; On the return, the reply contains
+a status, by default, and additionally, it contains the ID of the newly
+created cursor.
+<H2>
+Building and Installing</H2>
+I need to verify with Don Anderson, but I believe we should just build
+the server program, just like we do for db_stat, db_checkpoint, etc.&nbsp;
+Basically it can be treated as a utility program from the building and
+installation perspective.
+<P>As mentioned early on, in the section on <A HREF="#DB Modifications">DB
+Modifications</A>, we have a single library, but allowing the user to access
+the client portion by sending a flag to <A HREF="../docs/api_c/env_create.html">db_env_create()</A>.&nbsp;
+The Makefile is modified to include the new files.
+<P>Testing is performed in two ways.&nbsp; First I have a new example program,
+that should become part of the example directory.&nbsp; It is basically
+a merging of ex_access.c and ex_env.c.&nbsp; This example is adequate to
+test basic functionality, as it does just does database put/get calls and
+appropriate open and close calls.&nbsp; However, in order to test the full
+set of functions a more generalized scheme is required.&nbsp; For the moment,
+I am going to modify the Tcl interface to accept the server information.&nbsp;
+Nothing else should need to change in Tcl.&nbsp; Then we can either write
+our own test modules or use a subset of the existing ones to test functionality
+on a regular basis.

+# Syntax:
+# BEGIN	function_name  RPC #	{CODE | NOCLNTCODE | RETCODE | NOFUNC}
+#	CODE:	generate XDR and client code, return status
+#		Used for functions that just return a status and nothing else.
+#	RETCODE:generate XDR and client code, call return function
+#		(generate template return function)
+#		Used for functions that returns data.
+#	NOCLNTCODE:	generate only XDR and server functions
+#		Used for functions that are "different" on the client.
+#		Primarily used for envcreate (which is called from
+#		the dbenv->set_server method on the client side) and
+#		dbcreate, which is called from non-generated code.
+#	NOFUNC:	generate a client "unsupported function" with right args
+#		Used for unsupported functions.
+#
+# ARG	{IGNORE | STRING | INT | DBT | LIST | ID | CONST}  C-type varname
+#	IGNORE:	not passed to server
+#	STRING:	string passed to server
+#	DBT:	DBT arg passed to server
+#	LIST:	opaque list passed to server (NULL-terminated opaque list)
+#	INT:	integer passed to server
+#	ID:	cl_id from arg passed to server
+#	CONST:  do not generate COMPQUIET (for NOFUNC only)
+# FUNCPROT prototype
+# FUNCARG functiontype
+#	These two *MUST* go together and FUNCPROT *MUST* be first.  These
+#	are for the tricky user-supplied functions to some methods.  They
+#	are not supported in RPC, so will be ignored, but the complicated
+#	syntax of their argument requires we have a special flag for them
+#	that contains the verbatim text to use in the prototype and the
+#	c-type, respectively.  The FUNCARG must include the function, and
+#	must call it 'funcN', where N is the count of functions.  Almost
+#	always it must be func0.  A *very* few methods have more than one
+#	user-supplied functions, in those cases, it must be func0, func1, etc.
+#
+# All messages automatically return "status" and return that from
+# the call to the function.  RET's are additional things the server
+# may return.  RET is like ARG but does not need the IGNORE option.
+# RET	{STRING | INT | DBT | LIST | ID} varname [STRING | INT | ID]
+#	STRING:	string from server
+#	DBT:	DBT arg from server
+#	LIST:	opaque list from server (NULL-terminated opaque list)
+#	  Must have list type of STRING, ID or INT specified
+#	INT:	integer from server
+#	ID:	id from server stored in cl_id
+# END	function end.

+<A NAME="Database Commands"></A>Database Commands</H2>
+The database commands provide a conduit into the DB method functions.&nbsp;
+They are all fairly straightforward and I describe them in terms of their
+DB functions briefly here, with a link to the DB page where appropriate.&nbsp;
+The first set of commands are those I believe will be the primary functions
+used by most databases.&nbsp; Some are directly related to their DB counterparts,
+and some are higher level functions that are useful to provide the user.

+<P>This command will invoke the <A HREF="../../docs/api_c/db_create.html">db_create</A>
+function.&nbsp; If the command is given the <B>-env</B> option, then we
+will accordingly creating the database within the context of that environment.&nbsp;
+After it successfully gets a handle to a database, we bind it to a new
+Tcl command of the form <B><I>dbX, </I></B>where X is an integer starting
+at 0 (e.g. <B>db0, db1, </B>etc).&nbsp; We use the <I>Tcl_CreateObjCommand()&nbsp;</I>
+to create the top level database function.&nbsp; It is through this handle
+that the user can access all of the commands described in the <A HREF="#Database Commands">Database
+Commands</A> section.&nbsp; Internally, the database handle is sent as
+the <I>ClientData</I> portion of the new command set so that all future
+database calls access the appropriate handle.
+<P>After parsing all of the optional arguments affecting the setup of the
+database and making the appropriate calls to DB to manipulate those values,
+we open the database for the user. It&nbsp; translates to the
+<A HREF="../../docs/api_c/db_open.html">DB->open</A>

+<A NAME="Locking Commands"></A>Locking Commands</H2>
+Most locking commands work with the environment handle.&nbsp; However,
+when a user gets a lock we create a new lock handle that they then use
+with in a similar manner to all the other handles to release the lock.&nbsp;
+We present the general locking functions first, and then those that manipulate
+locks.
+<P><B>> &lt;env> lock_detect [-lock_conflict] [default|oldest|youngest|random]</B>
+<P>This command runs the deadlock detector.&nbsp; It directly translates
+to the <A HREF="../../docs/api_c/lock_detect.html">lock_detect</A> DB call.&nbsp;
+It returns either a 0 (for success), a DB error message or it throws a
+Tcl error with a system message.&nbsp; The first argument sets the policy
+for deadlock as follows:
+<UL>
+<LI>
+<B>default</B> selects the DB_LOCK_DEFAULT policy for default detection
+(default if not specified)</LI>
+
+<LI>
+<B>oldest </B>selects DB_LOCK_OLDEST to abort the oldest locker on a deadlock</LI>
+
+<LI>
+<B>random</B> selects DB_LOCK_RANDOM to abort a random locker on a deadlock</LI>
+
+<LI>
+<B>youngest</B> selects DB_LOCK_YOUNGEST to abort the youngest locker on
+a deadlock</LI>
+</UL>
+The second argument, <B>-lock_conflict</B>, selects the DB_LOCK_CONFLICT
+flag to only run the detector if a lock conflict has occurred since the
+last time the detector was run.
+<HR WIDTH="100%">
+<BR><B>> &lt;env> lock_stat</B>
+<P>This command returns a list of name/value pairs where the names correspond
+to the C-structure field names of DB_LOCK_STAT and the values are the data
+returned.&nbsp; This command is a direct translation of the <A HREF="../../docs/api_c/lock_stat.html">lock_stat</A>
+DB call.
+<HR WIDTH="100%">
+<BR><A NAME="> <env> lock_id"></A><B>> &lt;env> lock_id</B>

+<HR WIDTH="100%">
+<BR><A NAME="> <env> lock_get"></A><B>> &lt;env> lock_get [-nowait]<I>lockmode
+locker obj</I></B>
+<P>This command gets a lock. It will invoke the <A HREF="../../docs/api_c/lock_get.html">lock_get</A>
+function.&nbsp; After it successfully gets a handle to a lock, we bind
+it to a new Tcl command of the form <B><I>$env.lockX</I></B>, where X is
+an integer starting at&nbsp; 0 (e.g. <B>$env.lock0, $env.lock1, </B>etc).&nbsp;
+We use the <I>Tcl_CreateObjCommand()</I> to create the top level locking
+command function.&nbsp; It is through this handle that the user can release
+the lock.&nbsp; Internally, the handle we get back from DB will be stored
+as the <I>ClientData</I> portion of the new command set so that future
+locking calls will have that handle readily available.
+<P>The arguments are:
+<UL>
+<LI>

+function.&nbsp; It returns either a 0 (for success), a DB error message
+or it throws a Tcl error with a system message.&nbsp; Additionally, since
+the handle is no longer valid, we will call

+<P>This command performs a series of lock calls.&nbsp; It is a direct translation
+of the <A HREF="../../docs/api_c/lock_vec.html">lock_vec</A> function.&nbsp;
+This command will return a list of the return values from each operation
+specified in the argument list.&nbsp; For the 'put' operations the entry
+in the return value list is either a 0 (for success) or an error.&nbsp;
+For the 'get' operation, the entry is the lock widget handle, <B>$env.lockN</B>
+(as described above in <A HREF="#> <env> lock_get">&lt;env> lock_get</A>)
+or an error.&nbsp; If an error occurs, the return list will contain the
+return values for all the successful operations up the erroneous one and
+the error code for that operation.&nbsp; Subsequent operations will be
+ignored.
+<P>As for the other operations, if we are doing a 'get' we will create
+the commands and if we are doing a 'put' we will have to delete the commands.&nbsp;
+Additionally, we will have to do this after the call to the DB lock_vec
+and iterate over the results, creating and/or deleting Tcl commands.&nbsp;
+It is possible that we may return a lock widget from a get operation that
+is considered invalid, if, for instance, there was a <B>put_all</B> operation
+performed later in the vector of operations.&nbsp; The arguments are:

+<BODY>
+
+<H2>
+<A NAME="Debugging"></A>Debugging and Testing</H2>
+We have imported the debugging system from the old test suite into the
+new interface to aid in debugging problems.&nbsp; There are several variables
+that are available both in gdb as globals to the C code, and variables
+in Tcl that the user can set.&nbsp; These variables are linked together
+so that changes in one venue are reflected in the other.&nbsp; The names
+of the variables have been modified a bit to reduce the likelihood
+<BR>of namespace trampling.&nbsp; We have added a double underscore to
+all the names.
+<P>The variables are all initialized to zero (0) thus resulting in debugging
+being turned off.&nbsp; The purpose of the debugging, fundamentally, is
+to allow the user to set a breakpoint prior to making a DB call.&nbsp;
+This breakpoint is set in the <I>__db_loadme() </I>function.&nbsp; The
+user may selectively turn on various debugging areas each controlled by
+a separate variable (note they all have two (2) underscores prepended to
+the name):
+<UL>
+<LI>
+<B>__debug_on</B> - Turns on the debugging system.&nbsp; This must be on
+for any debugging to occur</LI>
+
+<LI>
+<B>__debug_print - </B>Turns on printing a debug count statement on each
+call</LI>
+
+<LI>
+<B>__debug_test -</B> Hits the breakpoint in <I>__db_loadme</I> on the
+specific iteration</LI>
+
+<LI>
+<B>__debug_stop </B>- Hits the breakpoint in <I>__db_loadme</I> on every
+(or the next) iteration</LI>
+</UL>
+<B>Note to developers:</B>&nbsp; Anyone extending this interface must place
+a call to <B>_debug_check()</B> (no arguments) before every call into the
+DB library.
+<P>There is also a command available that will force a call to the _debug_check
+function.
+<P><B>> berkdb debug_check</B>
+<P>
+<HR WIDTH="100%">
+<BR>For testing purposes we have added several hooks into the DB library
+and a small interface into the environment and/or database commands to
+manipulate the hooks.&nbsp; This command interface and the hooks and everything
+that goes with it is only enabled when the test option is configured into
+DB.
+<P><B>> &lt;env> test copy <I>location</I></B>
+<BR><B>> &lt;db> test copy <I>location</I></B>
+<BR><B>> &lt;env> test abort <I>location</I></B>
+<BR><B>> &lt;db> test abort <I>location</I></B>
+<P>In order to test recovery we need to be able to abort the creation or
+deletion process at various points.&nbsp; Also we want to invoke a copy
+function to copy the database file(s)&nbsp; at various points as well so
+that we can obtain before/after snapshots of the databases.&nbsp; The interface
+provides the test command to specify a <B><I>location</I></B> where we
+wish to invoke a <B>copy</B> or an <B>abort</B>.&nbsp; The command is available
+from either the environment or the database for convenience.&nbsp; The
+<B><I>location</I></B>
+can be one of the following:
+<UL>
+<LI>
+<B>none -</B> Clears the location</LI>
+
+<LI>
+<B>preopen -</B> Sets the location prior to the __os_open call in the creation
+process</LI>
+
+<LI>
+<B>postopen</B> - Sets the location to immediately following the __os_open
+call in creation</LI>
+
+<LI>
+<B>postlogmeta</B> - Sets the location to immediately following the __db_log_page
+call to log the meta data in creation.&nbsp; Only valid for Btree.</LI>
+
+<LI>
+<B>postlog</B> - Sets the location to immediately following the last (or
+only) __db_log_page call in creation.</LI>
+
+<LI>
+<B>postsync</B> - Sets the location to immediately following the sync of
+the log page in creation.</LI>
+
+<LI>
+<B>prerename</B> - Sets the location prior to the __os_rename call in the
+deletion process.</LI>
+
+<LI>

+number of mutex entries.&nbsp; After we successfully get a handle to a
+mutex we create a command of the form <B><I>$env.mutexX</I></B>, where
+X is an integer starting at&nbsp; 0 (e.g. <B>$env.mutex0, $env.mutex1,
+</B>etc).&nbsp;&nbsp;
+We use the <I>Tcl_CreateObjCommand()&nbsp;</I> to create the top level
+mutex function.&nbsp; It is through this handle that the user can access

+is sent as the <I>ClientData</I> portion of the new command set so that

+# Test054:
+#
+# This test checks for cursor maintenance in the presence of deletes.
+# There are N different scenarios to tests:
+# 1. No duplicates.  Cursor A deletes a key, do a  GET for the key.
+# 2. No duplicates.  Cursor is positioned right before key K, Delete K,
+#    do a next on the cursor.
+# 3. No duplicates.  Cursor is positioned on key K, do a regular delete of K.
+#    do a current get on K.
+# 4. Repeat 3 but do a next instead of current.
+#
+# 5. Duplicates. Cursor A is on the first item of a duplicate set, A
+#    does a delete.  Then we do a non-cursor get.
+# 6. Duplicates.  Cursor A is in a duplicate set and deletes the item.
+#    do a delete of the entire Key. Test cursor current.
+# 7. Continue last test and try cursor next.
+# 8. Duplicates.  Cursor A is in a duplicate set and deletes the item.
+#    Cursor B is in the same duplicate set and deletes a different item.
+#    Verify that the cursor is in the right place.
+# 9. Cursors A and B are in the place in the same duplicate set.  A deletes
+#    its item.  Do current on B.
+# 10. Continue 8 and do a next on B.

+#       occur relative to the new datum)
+#    f. Ditto for the two sequence tests, only doing a

+# Both pad_data and chop_data truncate data that is too long. However,
+# pad_data also adds the pad character to pad data out to the fixed length
+# record length.
+#
+# Which routine you call does not depend on the length of the data you're
+# using, but on whether you're doing a put or a get. When we do a put, we
+# have to make sure the data isn't longer than the size of a record because
+# otherwise we'll get an error (use chop_data). When we do a get, we want to
+# check that db padded everything correctly (use pad_data on the value against
+# which we are comparing).
+#
+# We don't want to just use the pad_data routine for both purposes, because
+# we want to be able to test whether or not db is padding correctly. For
+# example, the queue access method had a bug where when a record was
+# overwritten (*not* a partial put), only the first n bytes of the new entry
+# were written, n being the new entry's (unpadded) length.  So, if we did
+# a put with key,value pair (1, "abcdef") and then a put (1, "z"), we'd get

+		    The Berkeley DB Upgrade Tests
+
+Quick ref:
+
+    Running the tests:
+	(in tclsh)
+	% source ../test/test.tcl
+	% upgrade
+
+    Generating the test databases:
+	(in tclsh)
+	% source ../test/test.tcl
+	% gen_upgrade /where/you/want/them
+
+	(in your shell)
+	$ cd /where/you/want/them
+	$ perl $db_dir/upgrade/scripts/pack-3.0.pl
+	$ mv 3.0 $db_dir/upgrade/databases
+
+What they are:
+
+The DB upgrade tests are a framework for testing two main features of
+Berkeley DB:  the db_dump utility, and the "DB_UPGRADE" flag to DB->open.
+They work by taking a tarred, gzipped set of test databases and dumps, and
+verifying that the set of items is the same in the original database (as
+dumped by the version of DB that created it) as in the upgraded one,
+and is the same in the original database and in a new database generated by
+db_loading a db_dump.
+
+In db 3.X and higher, the upgrade test is repeated on a database with
+the opposite endianness to the system the database was generated on.
+
+How to generate test databases:
+
+Ordinarily, this is something that only very rarely has to occur;
+an archive of upgrade test databases can and should be kept, so ideally
+the generation step only needs to be done once for each major DB release.
+
+To generate the test databases, execute the command "gen_upgrade <dir>"
+inside a tclsh.  The method tests will run twice, once for each endianness,
+and all the databases will be saved in a hierarchy named by <dir>.
+
+Once the databases have been built, the archives expected by the upgrade tests
+must be built using the "pack" script, in upgrade/scripts/pack-<version>.pl.
+This script must be edited slightly to specify the location on a given system
+of the DB source tree and utilities;  it then converts the set of databases
+under the current working directory into a set of .tar.gz files containing
+the databases as well as flat files with their contents in item-by-item and
+db_dump formats.
+
+How to run the upgrade tests:
+
+Run "upgrade" from tclsh in the DB build directory.  By default, this
+looks in upgrade/databases, in the DB source tree.  An optional first argument
+can be used to specify an alternate directory.
+
+A note on 2.X tests:
+
+The 2.X packing script, as well as a patch against a 2.6.6 test directory
+to allow it to generate test databases, is in upgrade/generate-2.X.
+
+Note that the upgrade tests can be *run* on an the 2.X test archives
+without anything in this directory.  It is provided only for
+archival reasons, in case there is ever reason to generate a new
+set of test databases.
+
+XXX: Note also that it quite likely has paths hard-coded for a specific
+system that is not yours.
+
+Known Issues:
+
+1. The following 2.X databases trigger a bug in the db 2.X hash code.
+This bug affects only empty and near-empty databases, and has been
+corrected in db 3.X, but it will prevent the following from passing
+the db_dump test.  (They have been removed from the canonical database
+collection.)
+
+    2.X hash -- test026
+    2.X hash -- test038
+    2.X hash -- test039
+    2.X hash -- test040
+
+2. The 2.X recno versions of test043 cannot be made to pass the db_dump
+test because the 2.X version of db_dump has no -k flag and cannot preserve
+sparsely populated databases.
