Re: Clustering and changing qmgrs.
Thanks a MILLION for all the help. I basically suspended the cluster, left cluster, and joined cluster with the new production box. -Original Message- From: John M Hammond [mailto:[EMAIL PROTECTED]] Sent: Monday, June 24, 2002 4:28 PM To: [EMAIL PROTECTED] Subject: Re: Clustering and changing qmgrs. Bill, If I were you I would remove the first queue manager from the cluster by following the instructions in the "Queue Manager Clusters" manual.

Re: Clustering and changing qmgrs.
I've only just resubscribed to this list so apologies if someone has already
mentioned this but you might want to take a look at supportpac MS0G. This
lets you examine what's in your repository and clean it up if necessary.
This can be useful if you've removed things in the wrong order and confused
the cluster.

Subject: Re: Clustering and changing qmgrs.
Bill,
I probably should have explained a little further
Cluster queue managers communicate using the UUID to uniquely identify
specific queue managers. If you were to simply delete the old queue
manager and recreate the new one they will have different UUIDs and
therefore cluster communications will become problematic. I know there
have been some fixes in this area to allow for better handling of this
situation, but personally I wouldn't take the chance.
If I was trying to replace a cluster queue manager with another of the same
name I would always completely remove the queue manager before introducing
it's replacement.

John,
Thanks John, let me clarify something. When the process is complete there
will not be duplicate names. The current production system will be replaced
with a new production system with the same name. The only difference is
connection name.
Thanks

Re: Clustering and changing qmgrs.
There is a Queue Manager ID associated with QM, and if you just suspend the old one and connect the new one, those IDs will not match and disorder and chaos will intrude into your world... You need to make sure the cluster has completely forgotten that the old QM has ever existed.

Re: Clustering and changing qmgrs.
I think John's point is that if you are not patient and don't wait until your changes have been shuttled around the entire cluster (depending on how many repositories you have) before re-adding the new one, you could have the two events (leaving and joining) running into each other in the repository command queues and create duplication (or at least confusion). You'll want to verify the first qmgr has left by looking at the other repository queue managers (if there are others), before you attempt the join.
