I have two questions:
First of all, can we make a backout queue as cluster queue? I think it shoud be okay but my manager wants to be sure it can be done or someone has done it. so I want to be sure it can be done and works.
Second questions, I am working on setting up a backout queue in a two mqgr cluster scenario. The cluster has been set by my predecessor. It has only one FR.
I create a queue both in FR and the PR. Made them as cluster queue ( this is basically for testing). But I can not see the queue as a cluster queue in another queue manager.
One thing I am wondering is that, there is not to.pr cluster receiver channel but there is not channel from fr to pr. FR has two channels:
one clusrcvr - to.fr
another clussdr channel to.fr again
in pr there is one two channel one to itself and another to fr. My questions, should not we have to have sdr channel to pr from fr like to.pr ( from fr as clussdr)?
I have never worked in one fr queue manager cluster so wondering.
I would appreicate your response
thanks |

Yes. But why don't you just try it, and see.

Until an application running on the "other" QM references the queue, it won't be visible.

Does not it work just putting a message on that ( these) queue? I put a message on the queue going to the local version of the queue. But still the other queue manager does not show it up.
Is there any thing I missed ?

Can you please go to the PR and run:
dis clusqmgr(*)
I suspect your cluster is not fully operational... that would especially be the case if you have a ref to a temp qmgr in the response list.
Enjoy

Well, if you only have two QMGRs, then you should reconsider your decision to cluster them.
You need to document the architectural decision to cluster them (write down why it is thought to be a good idea to do that). If you cannot do this and have it sound like a good idea, then it probably is not.
If you cannot have two full repositories (which should explicitly point at one another), then WMQ Clustering is probably not beneficial.

I agree with you but I have just joined to them and they have a plan to migrate( still in MQ 5.3.11) in few months time. I have not had chance to see their new plan yet. |

I have some update.
In fact, there are two qmgrs besides one FR. We created one queue in each of the PR qmgr. these queues are visible from FR. But when we try to put message from PR to cluster queue associated to another PR, we can not do it.
We checked channels, channels are running. I tried to put the message connecting to to PR one after another but it says, 2085, object not available. We can put message connecting to FR, but still we can not see these queue from PR.
We are wondering what happened. Any suggestion?
thanks |

Did you do this? What was the result?
It sounds to me as well that the cluster is not fully opperational. You need to be checking that first.

Thsi is the exact output except the name changed.
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(MXXXXXx6A) CLUSTER(CLUS)
CHANNEL(TO.MQxxxx6A)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(XQPOSE6A) CLUSTER(CLUS)
CHANNEL(TO.XXXXXXXA)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(XQXXXXXXXB) CLUSTER(CLUS)
CHANNEL(TO.XXXXXXXB)
The qmgr on windows is FR. Two other qmgrs on Solaris 9 boxes are PR. The cluster queues are created in each of the PR. both of these queues are seen in FR but not in PR.
I am working on it this morning again, Let you know what happens.
Thanks a lot |

You have not done that yet. |
You won't "see" qclusters on PRs until someone has tried to use them - if the queue behind the qcluster is not locally defined.

Jeff,
Though we found that, that parciular cluster ( or qmgr) not sure yet, have problem, as we could do that in another cluster. Basically, when we define a cluster queue and put message and refresh the cluster ( not sure does it requrie or not) we can see the queue. Also, we would be able to put the mesage regardless, we can see the queue or not. That was my whole point. Because in this particular case, we were not able to do this.
Today, we did a similar setup in another test cluster and we were able to put the message into cluster queue, once it was created in one of the PRs/FR ( we tried both creating in FR and PR and in both case, it worked fine.).
We are still not sure what was /is causing the problem in that particular cluster.
Thank you all of those who provided suggestions/feedback. |

Could be that the chl status is having problems either between PF-FR/FR-PR or PR-PR.
You will have to check the channel status
