Hi,
I've simulated a clustering environment and it was successful. However, I've accidentally deleted the Queue Managers where the Cluster Channels are defined. As such, it constantly gave error message saying that the cluster channel cannot be found. May I know how I can rectify this problem as it affects the new queue managers which are not under the cluster?
Thanks!

Tom,
I'm not sure if I understand what's going on. You say "I've accidentally deleted the Queue Managers where the Cluster Channels are defined." It would seem to me if you deleted the queue managers which were hosting these cluster objects, then the object definitions shouldn't exist anywhere anymore. As far as getting an error message about the channel not existing, where were you getting this error? If you deleted the queue managers, it obviously wasn't coming from them. Then you asked "May I know how I can rectify this problem as it affects the new queue managers which are not under the cluster?" Since cluster objects (like cluster channels) are only registered with the repositories of those queue managers which are members of the same cluster, there should be no way that queue managers outside of the cluster are affected by the missing channels. Perhaps if you could describe in more detail the composition of the cluster, and exactly what you deleted, as well as when and where these errors are being generated, we can probably track down your problem...

Hi,
Here's the scenario:
Initially, I've tried to create the example cluster in MQ Series documentation using 2 QMs namely, LONDON and NEW YORK. residing on the same machine. After setting up the cluster, I am able to communicate b/w the two. Next, I create another QM, called QMTEST, which I did not add on to the cluster and it is still working fine.
After some time, being a bit forgetful, I must say, I accidentally deleted the 2 QMs, LONDON and NEW YORK. When that happens, under the error log for QMTEST, this message keeps appearing:
05/16/02 09:27:37
AMQ9519: Channel 'TO.LONDON' not found.
EXPLANATION:
The requested operation failed because the program could not find a definition
of channel 'TO.LONDON'.
ACTION:
Check that the name is specified correctly and the channel definition is
available.
I've tried various ways but I'm still not able to stop this message from appearing under the error log.
Kindly advise. Thanks!

I have never seen that problem, with a Qmgr outside the cluster, and not have told it where the RepositoryQmgr is.. and it created a channel by itself.... 
The quick way to get rid of it, is to create the LONDON qmgr again, and the follow the description in manualos of how to delete a qmgr from the cluster. That should do the trick... It worked for me previously

Check that cluster is still exist or not(double click on cluster folder in explorer).The current queue manager should be out of cluster.For that you make this queue manager is out of cluster and refresh it.verify is there any other cluster channels still exist on this queue manager.
