Has anybody had success with the following scenario in v6 and if yes how did you do it?
We run broker V6 on top of MQ V6 and DB2 V 8.2 on AIX.
The broker qmgrs are part of a cluster.
I tried the following:
Created a Topic and deployed to the cluster (A and C are full reps)
Created a Collective with A, B and C. (delta deploy)
Created a flow with a publication and deployed to broker on B
Subscribed on broker C with local Q on qmgr C.
I do not see any publications on B hitting C.
Am I missing something obvious?
Thanks

| If you put messages to a local queue manager and the cluster queue present in local queue manager then MQSeries will always put the message to local queue manager. It will never send the message to other cluster queues in the cluster queue managers. So this is the way MQSeries works. |

In Version 6 of MQ, that is no longer a restriction. You have options at the q level that allow you to override this behaviour.

Please all don't hijack my thread. This has nothing to do with clustering !!
P.S. PMR is under way.

Hi all, did anyone find out what the problem with this is. I am trying the same thing and cannot get it to work right.
I have two brokers running on two qmgrs. Both qmgrs are connected to each other via sender/receiver channels. Both brokers have the pub/sub flow deployed to them. I have a publisher seniding messages to broker1 and have the subscriber on broker 2. both broker1 and broker2 are connected to each other in a collective (done through the toolkit). Unfortunately the sbscriber does not receive the a message from the publisher - am i missig something. Please help. |

Did (either of) you successfully deploy the topology after creating the collective?

| Ok - right after I wrote my reply I simply tried redeoploying a complete configuration and after which i got it to work. It seems that the collective information was not deployed to all my brokers involved. One thing you can do to check if your subscriber is actually doing a proxy subscribe to the remote broker too is to getSubscriptions on your Configuration Manager in the Configuration Proxy Exciser tool supplied. That should return both the brokers involved and not just the one you are directly subscribing to. |

You only have to do a complete deploy when you need to deploy pub/sub topology changes - and I think that no other kind of deploy does actually deploy the pub/sub topology changes.
