Hi all,
I'm having trouble getting an eviction policy to work properly for objects that are not in a top-level tree node.
I'm using JBossCache as the 2nd-level cache for Hibernate. So, for example, if I am caching an object called my.package.MyClass, it ends up in a cache region called /my/package/MyClass. To set up an eviction policy for this region I am using the following config:
<attribute name="EvictionPolicyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
<!-- Specific eviction policy configurations. This is LRU -->
<attribute name="EvictionPolicyConfig">
<config>
<attribute name="wakeUpIntervalSeconds">5</attribute>
<!-- Cache wide default -->
<region name="/_default_">
<attribute name="maxNodes">5000</attribute>
<attribute name="timeToLiveSeconds">30</attribute>
</region>
<region name="/my/package/MyClass" >
<attribute name="maxNodes">10000</attribute>
<attribute name="timeToLiveSeconds">10</attribute>
<attribute name="maxAgeSeconds">10</attribute>
</region>
</config>
</attribute>
But the result I'm seeing is that the eviction policy for the specific region is not applied.
However, things work fine if I tell Hibernate to store objects in a top-level region (i.e. not nested) and provide an eviction policy for that region.
BTW, using JBossCache 1.4 with Hibernate 3.2.0 in JBoss 4.0.5.
Any help is much appreciated.
