Hi:
I want to put multiple queue managers in a cluster. While trying to do a setup with two queue managers with both of them as repository then it's working properly.
Now I want to add a third QM in the cluster. I've created all the channels in all associated QM's, all the channels are running fine but where do I specify that this queue manager belongs the same cluster as the other two belongs.
While doing the setup through MQExplorer then it's working properly.. in the QM property (cluster tab) it's showing the Cluster name and repository as NO.
Now how do I achieve this while I'm writing the scripts.
Pls. help.
Regards
Reeti |

When you are adding a new qm to an existing cluster, you can make it a non-repos or a repos qm. In your case it looks like you added a non-repos qm and hence it is showing repository as NO.
Not sure what you mean when you say "but where do I specify that this queue manager belongs the same cluster as the other two belongs". If you join a cluster as a non-repos, you DO NOT specify the cluster name anywhere else other than the clussdr and clusrcvr channels that you create.
If you join a cluster as a full repos, you have to first alter your qmgr repos(<your repos name>).
Not sure again what you mean by "writing the scripts".
Hope this helps.
Cheers

If a queue manager is a full repository, then you indicate which cluster it is a repository for using the REPOS attribute.
However, if a queue manager is a partial repository, then the cluster it is a member of is determined by the CLUSTER attributes in the cluster channels that you define between it and one of the full repositories.
There is nowhere where you say, "this queue manager is a member of cluster FOO." It knows it belongs to FOO simply because it has cluster channels defined to one of the full repositories for FOO. I think the reasoning behind this is because a queue manager can be members of more than one cluster, whereas I believe (correct me if I'm wrong) a queue manager can only be a full repository for one cluster.

A QM can be a full repository for more than one cluster.
In these cases, the QM is a repository for a Namelist, and that namelist contains all the Cluster names. Your QM and CLUSRCVR all point to this namelist.
If you want to add another cluster to this mess  , you just add a new entry to the namelist and you are all set. (Assumes you have a manually defined CLUSSNDR to the other full repositiry for every cluster).

Yeah, I hesitated as I wrote that line (hence the correct me if I'm wrong part), so thank you for clearing up my (and hopefully other's) confusion!
