That seems a dumb question, but I was confused since you mentioned the "master node" term. This is a concept we might change in JBM 2, but unless this is a nomenclature you choose at your architecture, JBM 1.4 doesn't have the concept of master-backup node. Every node is active and once one node "dies" the other/next node will get the data merged. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4165697#...
