Is this correct? | | I also want to ask why fail-over action is only trigerred by crashed condition? | I have a case where I need to shut down JBoss Messaging Server for operational thing. I want when I shut down one server, the connection will be failed over to another node, and when I put the server back, that server will share again the load of messages delivery with other servers. Is this scenario possible? When you failover, non persistent messages would be lost. Therefore we can't just fail over to redistribute load, since people would get upset if suddenly their non persistent messages disappeared. There are certain situations where it is possible to redistribute a connection, like, if there are no unacked messages in the session, but this gets complex.
