We are going to rebuild our production environment this year (onto new hardware). It is currently not HA clustered, but we have been approved for HA on the new hardware.
The environment will be:
Solaris 10 (in the global zone)
Veritas Clustering Solution
SAN for shared storage
WMQ 7.0.1
WMB 6.1
We have no ability to alter the way in which our old client applications connect; so, no client connection tables, no code that takes advantage of 7.0.1 reconnection functions.
We keep seeing that we don't need MC91 for an HA cluster on Veritas.

And, we also need to cluster WMB and we need for the IP address to failover, too.
Has anyone actually used a multi-cluster queue manager over VCS with a shared IP address (and clustered WMB,too)-- without the support packs? |

You don't need MC91 for MQ for VCS because Veritas has an MQ Agent. But they don't have a WMB agent.
We have MQ 6, WMB 6.1, DB2 9.1 running under VCS on RHEL 5. Works great. I knew we had to use IC91 for the WMB part. Since IC91 says it relies on MC91, I decided not you use the Veritas MQ Agent at all. We went MC91 and IC91. We use the Veritas DB2 Agent for the Broker's DB. Its the slowest part of the failover. If you can host your Broker DB in another cluster group, or on another server entirely, you will speed up your fail overs. Or go to WMB 7 and eliminate DB2 altogether!
My advice is to go with MC91 and IC91.

We had come to this conclusion also, but wondered if we were missing something.
It's interesting, though, that no one has replied that they have done a v7 multi-instance riding on top of a hardware clustering solution and NOT used the support packs. There seems to be a lot of information that states it can be done, but...
