Hi ,
I am having an issue with one of the replace commands for alias queue definitions...
Recently I tried to replace an alias queues base queue name with a new queue name but I was getting an error saying queue is already in use...
To brief U about the issue:
Existing queue definition : Alias Queue name : X
Base queue name : Y
A message flow was listening to this alias queue X .....
So I tried to change the base queue of X from Y to Z but when I tried to replace it, it is giving me an error saying "MQ Object is already in use"...
And same base queue is being used by some other alias queue as well which is listened by other message flow...
So I am not able to change the base queue of alias....
Could anyone of you please let me know what is the exact issue in here ??? |

The issue is exactly as described in your post - the object (the qalias) is currently in use by some application(s).
Briefly stop the application(s) using the QAlias definition, ALTER the TARGQ attribute, then re-start the application.

You might want to try with the WMQ Explorer. I seem to recall that it gives a warning about currently running applications.

Use the FORCE option on the ALTER command when changing the Alias queue.
Then hope the application is well written enough to re open the queue automatically the next time it uses it and gets an "Object Changed" MQ Reason Code. Or you can just restart the app to force it to reopen the queue after you changed it.
