Is it possible to set up two queue managers on the same physical machine (NT or HP-UX) and have the queue manager and channel names the same.

This is needed because we only have the one box for both development and production testing.

We are able to install the applications in separate instances, can we do the same with MQ and point the development application at the development queue manager without having to change any names or any of the queue, queue manager or channel names.

Can anyone help with this or point me in the right direction for any documentation that covers this.

Thanks
DMJ

DMJ,
you cannot do that without really dirty tricks. The queue manager name corresponds to a file system entry, typically underneath the installation directory. If you try to crtmqm a queue manager with a duplicate name, you will get an error message. On NT there might be registry entries that need to be uniquely addressed per queue manager.

Honestly, you definitely don't even want try to do that, because this is asking for trouble. Why do you need to have the same names for the queue managers? Do your applciations make a hardcoded reference on the MQCONN call?
You can have the same queue names on two different queue managers, so that's not a problem. And why would you care about the channel names being the same? They are not visible in any application anyway (unless they are client channels and you have hardcoded them in your applications, that is).
Would these two cloned queue managers be connected to other queue managers? What does your infrastructure look like?
Where in your applications do you make reference to MQ objects and how?
Can you provide some more details to understand your overall scenario?
Thanks,
Stefan
