Can we use cluster namelist to add qmgr as partial repos.

Could you please suggest on this below setup
QM1 & QM2----->Full repos TESTCLUS
QM3 & QM4------>Full repos TESTCLUS2
QM5-----> partial namelist(TCLUS) name(TESTCLUS,TESTCLUS2)

You think there's another reason IBM included the parameter on the channel definition?

Beware of overlapping clusters. While perfectly feasible, they can cause hair loss (through it being ripped out during troubleshooting), premature aging, sleepleness and psychological issues.

No. A qmgr becomes a partial repository (PR) when an object (queue, channel, etc.) is defined with the CLUSTER() attribute names the cluster in which the object is to be known.

or the CLUSNL parameter which is an option on both queues and channels

None of which has anything to do with the CLUSTER or CLUSNL properties of the QMGR object itself.

I never said they did. I was pointing out that both the CLUSTER and CLUSNL parameters are available on queues and channels, as a refutation of our worthy associate's claim that you needed to use the CLUSTER attribute on a queue or a channel to make it a PR; you can use the CLUSNL attribute to make a queue manager and it's objects a PR in multiple clusters.

I also (in my original reply) expressed my disquiet that this should be done.

I have not at any point in this thread referrenced the CLUSTER or CLUSNL attributes at the queue manager level (which would make the queue manager an FR not a PR) nor do I believe the OP is doing so.

The OP has mentioned nothing other than qmgrs.

How do you add a queue manager as a partial repository except by creating a cluster sender and a cluster receiver channel?

I couldn't speculate on what the OP believes. I can only work with what's been stated.

Yes .I have create the channel like this

DEFINE CHL(TO.QM5) CHLTYPE(CLUSRCVR) CONNAME('LOCALHOST(3560)') CLUSNL(TCLUS)

DEFINE CHL(TO.QM2) CHLTYPE(CLUSSDR) CONNAME('LOCALHOST(3557)') CLUSNL(TCLUS)

Are the channels in RUNNING state?

What are the values of CLUSNL(TCLUS)?

Best practice (as far as I am concerned) is to have separate CLUSSDR/CLUSRCVR channels per cluster than to name-list one channel in multiple clusters - it makes fault diagnosis a lot easier, and prevents you getting tied up in knots when trying to determine message flow routes when you also have a queue shared in multiple clusters.

He does mention that in the question to be fair.

However, I agree with the sentiment of having separate channels, one in each cluster. It makes everything easier, starting, stopping channels, telling what's gone wrong when something stops, etc.

Nope ..The channel are not running...

I know that we can add the qmgr in partial repos by adding the channel to full qmgr.

My doubt if we define the cluster namelist object and I need to keep the qmgr in partial repository mean i will not alter the qmgr reposnl attribute. for this like clustering the cluster namelist should be full repository

pls advice
