Thanks a lot Steve and Alan, appreciate your prompt helps. I guess I have not posted my ideas clearly. Let me describe it below for your better information.
After going through the link provided by Alan, I realize that HA is only to group two nodes into a cluster for high availability. Clients or Exchanges need to connect to virtual IP for message communication. QPID Messaging Bus itself is HA, but Clients or Exchanges connect to QPID are not automatically HA ready. Please correct me if my understanding is wrong. What we are intended to achieve is that we have two physical boxes, one box shall have a server instance, for example a billing utility, running as primary service provider, another box shall have an identical billing utility running which is a hot-backup of the primary one. Messages passed to primary instance will be processed as normal, while messages duplicated to backup instance will be processed and update its internal status only. Once Primary instance or primary box is down, backup instance or box will take over. Is there any existing mechanism provided by QPID to achieve this purpose to ease our effort? Looking forward to your insights.
