[jboss-jira] [JBoss JIRA] Closed: (EJBTHREE-790) Include partition name in cluster name of caches

[Brian Stansberry (JIRA)]

     [ http://jira.jboss.com/jira/browse/EJBTHREE-790?page=all ]

Brian Stansberry closed EJBTHREE-790.
-------------------------------------

    Fix Version/s: AS 5.0.0.CR1
                       (was: HEAD)
       Resolution: Done

The bit about including the partition name in the JGroups cluster name was fixed long ago. At this point I'm not going to do anything about the bit I mentioned on analyzing the bean's partition and identifying the correct cache from that. People need to specify the cache's properly (via @CacheConfig) if they deploy more than one partition.

> 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>
