What is the value of JMS clustering in WLS 6.1?
Consumers and producers can access a destination from any server in the cluster, independent of where the destination actually resides. This provides for location transparency. Note that it is necessary to configure the JMSServer on one of the members of the cluster (not the Admin Server) for this location transparency (which uses replicated JNDI). If the server on which a given producer or consumer resides goes down, others can still access the destination. However, if the destination goes down, then all the producers and consumers are useless. If you lose a JMS server all transactions for which that server is enlisted are rolled back. JMS continues to work elsewhere in the cluster, just not on the server that went down. When that server comes back up then that server will again provide JMS service. When the server comes back up the messages are then pushed to or pulled by consumers as appropriate. Reboot the server and it should just work. For example, assume a Topic is deployed on s
