    cluster entity EJBs with invalidation

    Pedro Salazar Newbie

      Greetings,

      When I deploy my Read-Only Entity Beans for invalidation target I must select the configuration "Standard CMP 2.x EntityBean with cache invalidation" from the jboss configurations, because is the only profile with invalidation.

      Since I would like to deploy them as cluster EJBs (jboss.xml: < clustered>true< /clustered>) I received always a warning that there isn't a single clustered invoker available in that configuration:

      WARN [org.jboss.ejb.EntityContainer] *** EJB 'X' deployed as CLUSTERED but not a single clustered-invoker is bound to container ***
      


      Questions:

      - the cluster configuration of EJBs means that when a entity bean is load on one jboss instance, the cluster replicates these beans to the others instances? It's recommended? I'm trying to get the best performance, with invalidation, but I don't know if the cluster replication bottleneck is acceptable.

      - can I extend the configuration "Standard CMP 2.x EntityBean with cache invalidation" to support cluster (clustered-invoker) or add a invalidation feature to a cluster existent configuration?

      Regards,
      Pedro Salazar.
