Brian Stansberry commented on EJBTHREE-790:
-------------------------------------------

It's not any issue with the caches being isolated.  But if you have more than one, for example, EJB3 SFSB cache, when your SFSB is deployed the deployment process needs to pick the correct cache to store your beans in.  You can tell it which one to use in your bean config, but that's easy for people to forget or mess up.  Would be nice if we could make it a bit easier.

> For ejb3-entity-cache-service.xml and ejb3-clustered-sfsbcache-service.xml the ClusterName should include the partition name. Here is why:
> We have 3 test instances and the two production cluster nodes within the same subnet (VLAN). The test instances have unique partition names (TEST1, TEST2, TEST3) and the production nodes share a common partition name (PROD).  In the default configuration all five nodes would form a cluster for the entity and SFSB caches. This would severely disrupt data consistency! We have solved this by including the partition name in the cluster name in the cache MBeans:
>     <attribute name="ClusterName">EJB3-entity-cache-${jboss.partition.name:DefaultPartition}</attribute>
