Hi, I am having a problem on how to set up queues to share message.
Here is the scenerio:
QMgr 1, 2 and 3. They are in a cluster.
I would like to have a queue in QMgr 1 to host messages and a queue in both QMgr 2 and 3 to get (read) messages. Can someone give me a direction?
Thanks |

Review Queue Sharing Groups, which is only available on the mainframe. Otherwise, you can't do what you want.

Here's how clustering works.
On some queue manager QM1, I have a qlocal A. I share that queue in the cluster. Now, I can see both a qlocal A and a qcluster A on QM1 , if I display all the queues. On QM2 and QM3 that are in the same cluster, I can see only the qcluster A.
If I want to GET from that queue A, I have to connect to the queue manager QM1.
If I want to PUT to that queue A, I can do this while connected to any queue manager, QM1, 2 or 3. When messages are PUT to a qcluster, then the workload balancing algorithm will try to balance the message load between every qcluster of that name.
So what do you mean by "host"?
It sounds like what you want is to define a queue A on both QM2 and QM3, and then put messages from QM1.
But you will never be able to get the SAME message from BOTH QM2 and QM3. Unless you use something like MirrorQ to put to a distribution list - but bear in mind that mirrorQ is a sample program, and is not supported by IBM at all.

Thanks for the information.
To put messages, I can use any queue managers in a cluster. But to get messages, I can only get it from the repository queue manager. I would like to get message from other Q Managers as well. |

You can only get messages from a queue manager that has the queue as a qlocal.
This can be any queue manager in the cluster, or many queue managers in the cluster, or all the queue managers in the cluster.
