Hi,
We have an MQv7.0 set up of two queue managers, running on MSCS - that is, we set up microsoft clustering resources for shared disks/ips etc. on W2003 and ran the MQ MSCS commands to move the QM data and logs to the shared directory. There are two nodes in the MSCS cluster. We've been running this fine in all environments for a while now with no major problems (touch wood!!).
However, I see the latest FP for MQv7 is 7.0.1.1. The question is, how does the FP installation work on an MSCS MQ environment - i.e. given we have split the qm/logs files from the MQ source code? Does the FP simply run against the source code only (and qm/log files don't need to know anything about the upgrade) or is it more complicated and some manual steps of some sort have to be done to upgrade both source code and qm data elements?
Thanks in advance,
Rich |

Yes.
Note that you'll need to run any fix pack against both nodes before you attempt to fail over. Not an issue with this particular FP but it can be the case that the queue manager automatically updates logs or queues when restarted. Which obviously causes problems if you fail over to a lower level queue manager.
So far as I remember there's never been a manual update step for the data, even for the big log change that came in with v6. The notes for the FP will give full details (as they did for v6, warning that if you wanted to roll back to v5.3 you needed a system backup of the log files as the format was changed).

Fantastic, many thanks.
Is the FP install simply(!) a case of :
1. Stopping the QM cluster resource on the active node
2. Apply FP to node 1
3. Apply FP to node 2
4. Bring QM cluster resource online
5. Fail over QM to other node to ensure it runs ok

Nah. To much outage time. Your H.A., remember? 
1. QM is running on Node 1.
2. Pause Node 2.
3. Upgrade / reboot Node 2.
4. Resume Node 2.
5. Swing the QM to Node 2.
6. Pause Node 1.
7 . Upgrade and reboot Node 1.
8. Resume Node 1.
9. Fail QM back to Node 1 to test Node 1.

Cool. By reboot I assume you mean literally a server restart?

This is Windows. Absolutely a server restart.

Thanks all.
Re. Fix Packs, do I have to apply Fix Packs to MQ Client installs and MQ extended transactional clients (and if so is the same FP software used or is there a seperate client version of the FP?). I've read the 7.0.1.1 FP readme but no mention of clients?
Thanks again. |

In an ideal world all your infrastructure should be at the same patch level, and no there is no separate FixPack for clients, and only installed components will be updated by the FixPack.

Defintely agree about the consistency of patches across environments, thats what we want to do.
So I apply the same FP to the client/extended transactional client installs (as well as the server install) and it will update accordingly?
Great stuff |
