Using JMS and MQ7, once connection is routed by CCDT, if we created multiple JMS sessions from the JMS connection, is there any way to guarantee that the JMS sessions all connected to the same QM originally dispatched by the CCDT?
We tested this but found that the JMS session created from the JMS connection (connected via CCDT) actually connects to different QMs in the QM group....this is not our desired behavior. We only want the CCDT to decide the first QM via the JMS connection object. Any JMS session object spawn from the JMS connection should point to the same QM.
Appreciate your help!!! |

Working as designed.  Read up on the V7 client manual and the way the CCDT table works in V7  . You can control the behavior through some parms, but if you used the defaults it is working as designed.
Have fun

Do you mean AFFINITY=PREFERRED?
The problem is that it stick to the same QM from the QM Group per machine basis, not on JVM basis.... |

And I mean define JMS Session as extensively as possible.
Make sure there is no possible confusion with MDB Session...
