Hi there, I've got an System with two servers on each of them I've got a JBoss and a postgresql database. The both Jboss-servers are clustered. The postgres-databases are replicated by c-jdbc. Now we need also jms (and of course clustered). As described in the documentation I've changed the default-datasource from hsqldb to the postgres-database. But can I replicate them also with c-jdbc? Which node writes to the database if the node receive an message? Are both writing to their own database? Or is it possible to replicate them? The documentation wasn't very helpfully on this issue. Thanks for your help. Marc View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989589#...
