Hi - I am also new to the clustering aspects of JBoss and suffering similar confusion I think about entity persistence in a cluster. Section 10.3 here: http://labs.jboss.com/file-access/default/members/jbosscache/freezone/doc... implies replication via the cache is persisted ( ? ) I've got a test setup with 2 machines in a cluster which seems to work (I can see the cache replication working via JMX console) but what I also see despite entities being replicated in the cache, the DB is still always being queried (I can see the query count increase in the DB (MySQL) tools). I would expect not to see a DB access for cached entities. Any thoughts on that one ?
