<p>Secondary databases accept <code class="classname">SecondaryConfig</code>
|
|||
|
|
objects. <code class="classname">SecondaryConfig</code> is a subclass of <code class="classname">DatabaseConfig</code>,
|
|||
|
|
so it can manage all of the same properties as does <code class="classname">DatabaseConfig</code>.
|
|||
|
|
See <a class="xref" href="dbprops.html" title="Database Properties">Database Properties</a> for more information.</p>
|
|||
|
|
<p>In addition to the <code class="classname">DatabaseConfig</code> properties,
|
|||
|
|
<code class="classname">SecondaryConfig</code> also allows you to manage the following properties:
|
|||
|
|

|
|||
|
|
<code class="methodname">SecondaryConfig.setAllowPopulate()</code>
|
|||
|
|
</p>
|
|||
|
|
<p>If true, the secondary database can be auto-populated. This means
|
|||
|
|
that on open, if the secondary database is empty then the primary
|
|||
|
|
database is read in its entirety and additions/modifications to the
|
|||
|
|
secondary's records occur automatically.</p>
