I am working on Migrating MQ V5.3 Cluster Queue Managers from HP to AIX. The idea is to not to disturb the cluster setup on HP until the cutover time. To make things simple or complicated we decided to copy /var/mqm/ directory from HP to AIX, made few changes in qm.ini and mqs.ini files. So, the queue managers on both HP and AIX are the same, next thing we are trying to isolate the AIX queue manager from the cluster and applications connected to each queue manager step-by-step. I am not going to start the listener until I isolate the queue manager from the rest of the cluster queue managers. Now, I have couple questions here:
1. Is it good to suspend QM on AIX? If so, When I suspend queue manager from cluster namelist on AIX, what happens to the same queue manager on HP which is the same name and within the namelist, will that also be suspended or HP queue manager will be part of the namelist?
2. Or is it a good idea to change the QM listener port on AIX other than what’s used on HP?
Any ideas or suggestions are appreciated.
Regards,

Um.
Don't do this.
You'll end up with two queue managers with the same QMID in the cluster.
This is a *bad* thing.
Create the AIX qmgr from scratch. Rebuild any necessary objects using saveqmgr - except do not share any queues in the cluster.
As you feel like it, share particular queues on AIX in the cluster, connect apps, and unshare the HP queues.

Jeff,
Thanks for your quick reply. Is there a way to change the QMID on AIX?

Yes.
Drop and recreate the qmgr...
I don't think you can change it any other way.

Jeff,
once again, SUSPEND QMGR CLUSNL(ABC_CLUSTER_NAMES) will not suspend the (AIX) 2nd queue manager right? Just want to make sure all other possibilities.
Thnx |

Messages will get delivered to a SUSPENDED qmgr only if no other destinations are available.
But they can still get sent there.
