Hi,

We need to create a production environment with MQ clustering setup in a active active broker configuration.

So QM1 - BRK1 (active)
and QM2 - BRK2 (active)

Also QM1 and QM2 are clustered.

Now if Broker on node 1 goes down, the messages still go to the QM1 (since QM1 is not down and clustering algorithm will route to it). So messages routed to QM2 get processed but not the ones going to QM1.

To avoid this, we are thinking of multi-instance broker setup and that needs a multi - instance queue manager setup . Also from what I have gathered in the infocenter, is that if the active broker goes down but not the active queue manager, the standby multi-instance broker/Qmanager will not be activated. It gets activated only if the active instance of queue manager goes down. This would still mean that if only the active broker goes down but not the QM, messages will still come to QM1 (assuming QM1 is active and QM2 is passive) and not get processed.

So is the only way around this is to create some scripts in the server which will end the queue manager service as soon as broker goes down? I have not figured how to write that script but sripting is the only thing that comes to mind to stop queue manager as soon as broker goes down. The client requirement is that as long as any of the environment (BRK1 or BRK2) is active, messages should keep on getting processed.

The client does not have HACMP. Setup is MQv7.5 and IIB9.

Any suggestions welcome please.
