There's a conundrum i will definitely face soon...
"How can you determine Full repositories among 600 qmgrs on AIX. You do not have access to MQ Explorer"
Is there a plausible answer to this, other than traversing each of the queue managers' (or going to 20 queue managers and checking their CLUSSDR channels...and whichever queue manager isolates the maximum number of times is a FR...out of the box thought!)
Thanks. |

And what's wrong with using the DISPLAY CLUSQMGR command with the appropriate 'filter'?

It should be possible to answer this question by running DISPLAY CHANNEL on at most two queue managers.
If it's *not* possible with at most two queue managers, then the cluster is set up wrong. |

One of two qmgr attributes determine if it is an FR, namely:
ALTER QMGR REPOS(cluster name goes here)
ALTER QMGR REPOSNL(cluster name list goes here)

I'd start by asking those responsible for managing your WMQ environment for their WMQ inventory documentation. Surely a 600 qmgr organization will have such documentation.
If not, then doing the inventory yourself will require that you visit each qmgr to determine if it's in a cluster or clusters, which cluster(s), and what role (FR or PR) it assumes in the cluster(s).

still think DIS CLUSQMGR(*) WHERE(QMTYPE EQ REPOS) is easier...

| That would still give me only one FR (!). Suppose there are 3 FR and there is no namelist. This is a hypothetical situation. |

Really? Why do you think that?

If you have three FRs then you have not observed the holy grail of clusters: " The number of Full Repositories shall be two, no more, no less. Two shall be the number you shall count...". And, what has a potential namelist got to do with it?

Hypothetical or not, the above remains true.

mmmm Holy handgrenade of antioch coming into play on a mq cluster discussion that is abstract!!!!

| I can use DISPLAY CLUSQMGR within one queue manager. So, to find out the 2nd FR i will need to use it within another queue manager. |

Why not just try it in one and see what results?

While you may define more than 2 FRs in a cluster, clustering software will only make use of 2.
So, you don't have access to the WMQ Explorer tool. In order to use the WMQ Explorer, the GUI admin tool, it must connect to each qmgr you intend to manage. You are left with some other performance tool, or using runmqsc; but each will require a connection.

All qmgrs in a cluster need to connect to an FR, including the other FR. So, yes, if you connect to an FR, you can determine which is its FR.

I repeat.
I can do this with two DISPLAY CHANNEL commands, one on each of two queue managers.
Give me any queue manager in the cluster as the first one, and allow me to choose the second one.
If this does not provide the full list of all FRs in the cluster, then the cluster has more than two FRs and is broken. |

The first queue manager tells you which queue manager is one of the FRs. That FR will tell you which queue manager is the other FR.
