Date Thu, 28 Feb 2013 08:37:12 GMT
Jessy created AMQ-4353:
--------------------------

             Summary: Behavior of "Exclusive Consumer" configured for queues on AMQ : Behavior
of Master Slave Topology 
                 Key: AMQ-4353
                 URL: https://issues.apache.org/jira/browse/AMQ-4353
             Project: ActiveMQ
          Issue Type: Task
          Components: activemq-leveldb-store, Broker
    Affects Versions: 5.5.1
         Environment: Linux,AMQ 5.5.1
            Reporter: Jessy



I noticed the following behavior when I set “Exclusive consumer” property for a queue
configured on AMQ 5.5.1 installation

If say for Queue A, there were 2 consumers : con1 and con2 , both consumers are up all the
time .
Say, one of them con1 becomes the master and consumes the message
Successive message are not consumed by  con1, where-in con2 is also found to consume the message..
There is alternative consumption ,once by con1 and con2.

Master is not the master all the time ..even if  master is up,slave consumes the message in
alternative fashion.
Is this the intended behavior for “Master-Slave” paradigm?
Is there any API exposed to identify which is the master and slave ,which would help us in
our logging to identify which is the current consumer of the message.
