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 for the corresponding methods (for example, +the <a href="../../api_c/env_set_data_dir.html">DB_ENV->set_data_dir</a> documentation includes NAME VALUE pair +information Berkeley DB administrators can use to configure locations for +database files). +<p>The DB_CONFIG configuration file is intended to allow database +environment administrators to customize environments independent of +applications using the environment. For example, a database +administrator can move the database log and data files to a different +location without application recompilation. In addition, because the +DB_CONFIG file is read when the database environment is opened, +it can be used to overrule application configuration done before that +time. For example a database administrator could override the +compiled-in application cache size to a size more appropriate for a +specific machine. +<table width="100%"><tr><td><br></td><td align=right><a href="../../ref/env/error.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../reftoc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/env/naming.html"><img src="../../images/next.gif" alt="Next"></a> +</td></tr></table> +<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> +</body> +</html> |
