CLUS1 is cluster with two FullReps QM1 and QM2 and one PR QMGR. Both QM1 and QM2 have a cluster named QLC1.
I am not able to see this queue(s) when I gave dis qc(*) or thru MQ explorer

So install them, or use IH03.

Where exactly were you when you attempted the display command (and could not see...)? A FR? A PR?

Do you see the queues with dis QL(*)?

Exactly how did you look for the queues with the WMQ Explorer? In the Clusters folder? Somewhere else?

tried dis qc(*) from QMGR (which is a PR)
And thru rfhutil too am not able to see the cluster queues while loading the PR, QMGR.

For dis ql(*) am able to see the queue in both FRs

yes. Also looked in MQexplorer, under PRs folder of the cluster

Have you actually set the cluster attribute of the queues you wish to share in the cluster? Have you checked for typos in the name etc.?

"...while loading the PR..." is not WMQ terminology. What exactly does this mean?

PRs only contain cluster information for objects that apps on that PR qmgr have expressed interest in. So, dis qc(*) on a PR would have little info about cluster objects. Whereas, dis qc(*) an an FR would have all info about cluster objects.

Make sure you enclose the name of the 'clustername' in apostrophes.

Yes. I am able to see two QLC1 queues in QM1(dis qc(*)) and in QM2. No typos were present

I meant that I selected the PR in the queue manager property in rfhutil and clicked "Load names" button.

Sorry for a typo in typing my question. Have bolded it for clarity

Something that was drummed into me very early on in my WMQ life, and to amplify what bruce2359 stated earlier:

"...a PR knows what it needs to know about the cluster when it needs to know it, and then remembers. An FR knows all about the cluster all of the time..."

If you have not tried to resolve a cluster queue from your PR you will not see any cluster queue objects appear.

For clarity, is QMGR the actual name of the PR qmgr? If not, what is the name of the PR qmgr?

If on an FR, or qmgrs where the real local queues are defined (PR or FR), you can see the real local queue QLC1, with WMQ Explorer or runmqsc dis ql(*), then you are good so far.

If on a PR (where there is NO local instance of QLC1), and you have run NO apps that drove the name resolution process, then the WMQ Explorer and runmqsc will have NO information about those cluster queues.

This is normal, expected, and well-documented behavior of cluster repository management.

Please research name resolution.
