Hi folks, I'm hoping someone here can help me out. I've got ActiveMQ setup in JBoss, with two queues, one in and one out.
I've got one MDB per queue. I'm using the JCA approach for configuring ActiveMQ in JBoss, and I'm using the VM broker. While I have one outbound queue, and one outbound MDB, each message can go to a different destination, and for a variety of reasons its not feasible to create one queue per concrete destination. I've been setting the JMSXGroupID on outbound messages but it doesn't appear to be doing any good. Based on my debug output outbound messages to the same target group are handled by multiple instances of the MDB, so messages to the same destination are handled in parallel, which is not what I expected to see with the JMSXGroupID. I was expecting to see that messages to different destinations (in different groups) would be handled in parallel, while messages to the same group would be processed serially. Have I misunderstood the expected behavior of groups, or do I just not have it setup properly? I haven't done anything special to enable ExclusiveConsumer, but I see groups are mentioned as an extension of that. Does that mean that ActiveMQ has to be configured for ExclusiveConsumer before grouping will work as expected? If so, how does one do that using the JCA interface, or can one? -- View this message in context: http://www.nabble.com/Groups-tf2952450.html#a8257544 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
