<h1 align=center>Initializing a new site</h1>
<p>Perform the following steps to add a new site to the replication
group:
<p><ol>
<p><li>Do an archival backup of the master's environment, as described in
<a href="../../ref/transapp/archival.html">Database and log file
archival</a>. The backup can either be a conventional backup or a hot
backup.
<p><li>Copy the archival backup into a clean environment directory on the
client.
<p><li>Run catastrophic recovery on the client's new environment, as described
in <a href="../../ref/transapp/recovery.html">Recovery procedures</a>.
<p><li>Reconfigure and reopen the environment as a client member of the
replication group.
</ol>
<p>If copying the backup to the client takes a long time relative to the
frequency with which log files are reclaimed using the
<a href="../../utility/db_archive.html">db_archive</a> utility or the <a href="../../api_c/log_archive.html">DB_ENV->log_archive</a> function, it may be
necessary to suppress log reclamation until the newly restarted client
has "caught up" and applied all log records generated during its
downtime.
<p>As with any Berkeley DB application, the database environment must be in a
consistent state at application startup. This is most easily assured
by running recovery at startup time in one thread or process; it is
harmless to do this on both clients and masters even when not strictly
necessary.
