<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:
|
||
</p>
|
||
<div class="itemizedlist">
|
||
<ul type="disc">
|
||
<li>
|
||
<p>
|
||
<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>

|
||
<li>
|
||
<p>
|
||
<code class="methodname">SecondaryConfig.setKeyCreator()</code>
|
||
</p>
|
||
<p>Identifies the key creator object to be used for secondary key
|
||
creation. See <a class="xref" href="keyCreator.html" title="Implementing Key Creators">Implementing Key
|
