> I think there is issue related to expiration of JBoss cache entries, which are used for picketlink cache. Right now, JBoss cache in server/default/deploy/gatein.ear/02portal.war/WEB-INF/organization/picketlink-idm/jboss-cache.xml and jboss-cache-cluster.xml is configured to use Expiration algorithm:
>  <eviction wakeUpInterval="5000">
>    <default algorithmClass="org.jboss.cache.eviction.ExpirationAlgorithm"
>      eventQueueSize="1000000">
>      <property name="maxNodes" value="100000" />
>      <property name="timeToLive" value="120000" />
>      <property name="warnNoExpirationKey" value="false" />
>    </default>
>  </eviction>
> Problem is that ExpirationAlgorithm requires support in Java code for eviction, which is mentioned in http://docs.jboss.org/jbosscache/3.1.0.CR1/userguide_en/html/eviction_policies.html#d0e3646 . There is need to call something like:
>   // sets the expiry time for a node
>   cache.getRoot().addChild(fqn1).put(ExpirationConfiguration.EXPIRATION_KEY, future);
> otherwise node is never evicted periodically. And I am seeing that this is not called in Picketlink code and GateIn+Picketlink integration code. And I am seeing in JMX that nodes are never evicted automatically after some time. Fact is that entries are cleared from cache only by trigger of some events (For example after update of some user are entries for this user evicted from cache).
> Last week I was working on application for adding users into GateIn IDM database only with plain SQL. And when I create users, I am not seeing them in organization management portlet because query for get all users is never evicted from cache. I need to restart my GateIn portal or trigger JMX eviction of picketlink cache (Operation "invalidateAll" on MBean exo:name=plidmcache,portal="portal",service=PicketLinkIDMCacheService .
