Hi Guys,

I am new to MQ clustering.
We are using JMS to connect the queue manager(EAIQM01) and send the messages.
I have a problem here when EAIQM01 is down we are not able to receive the messages, I would like other queue manager EAIQM02 pick those messages and process them.

Could you guys suggest me to direct me to overcome this problem.

As you have discovered now you can only retrieve messages from a queue local to a qmgr you are connected to.

If you are using a true asynchronous application and the order of the messages does not matter nor does the processor (EAIQM01 or EAIQM02) have the application use a cluster alias in the reply to qmgr field of the reply to destination or of the destination... and make sure the destination does have bindings = NOTFIXED set...

The cluster load balancing should then take care of future messages. For the ones in transit you will have to wait until EAIMQ01 comes back up.

Have fun

If your environment is on z/OS, you can also use Queue-Sharing...where any qmgr in the QSGroup can pick up the message.

If you upgrade to MQ v7.0.1, you can set up a multi-instance qmgr.
