Replication can now be enabled and configured in the SQL
|
||
layer using pragmas. The pragmas
|
||
<code class="literal">replication_local_site</code>,
|
||
<code class="literal">replication_initial_master</code>, and
|
||
<code class="literal">replication_remote_site</code> can be used to
|
||
configure the replication group. Note that when the BDB SQL
|
||
replicated application is initially started, a specific master
|
||
site must be explicitly designated. After configuring the
|
||
replication group, start replication using <code class="literal">PRAGMA
|
||
replication=ON</code>.
|
||
</p>
|
||

To display replication statistics in the dbsql shell, use:

<pre class="programlisting">dbsql> .stat :rep</pre>
