[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Second Level Cache with JBoss TreeCache

Hi, we use the JBoss TreeCache for the Hibernate Second Level Cache. I found out that each Second Level Cache Entity is held in a separate node (for example, there are one node for OrderType[id-1] and one node for OrderType[id-2] '/com/sales/hibernate/OrderType/com.sales.hibernate.OrderType#1' and '/com/sales/hibernate/OrderType/com.sales.hibernate.OrderType#2'). Because we have many Second Level Cache Enties our TreeCache have thousands of nodes. I actually expected that each node is for one EntityType (OrderType.class) and the map in the node holds the Enties of this type (OrderType#1; OrderType#2). We use JBoss 4.0.5.GA with Hibernate 3.2.4.ga. The treecache.xml: | <?xml version="1.0" encoding="UTF-8"?> | <server> | <mbean code="org.jboss.cache.TreeCache" | name="jboss.cache:service=TreeCache"> | | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | | <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | | <attribute name="CacheMode">LOCAL</attribute> | | <attribute name="ClusterName">Sales_Hibernate_Cache</attribute> | | <!-- | Max number of entries in the cache. If this is exceeded, the | eviction policy will kick some entries out in order to make | more room | --> | <attribute name="MaxCapacity">7000</attribute> | | <!-- | The max amount of time (in milliseconds) we wait until the | initial state (ie. the contents of the cache) are retrieved from | existing members in a clustered environment | --> | <attribute name="InitialStateRetrievalTimeout">20000</attribute> | | <!-- | Number of milliseconds to wait until all responses for a | synchronous call have been received. | --> | <attribute name="SyncReplTimeout">10000</attribute> | | <!-- Max number of milliseconds to wait for a lock acquisition --> | <attribute name="LockAcquisitionTimeout">15000</attribute> | | <!-- Max number of milliseconds we hold a lock (not currently | implemented) --> | <attribute name="LockLeaseTimeout">60000</attribute> | | <!-- Name of the eviction policy class. Not supported now. --> | <attribute name="EvictionPolicyClass"></attribute> | </mbean> | </server> | What can i do to get the expected behavior?
