Hi,
i have two QMs in a production environment. One was located on a machine which has been migrated. The application was rewritten, so no second QM is needed anymore. But the project missed to reconfigure a few applications, which still wrote messages to remote queues. They now reside in the corresponding transmission queue. Project already changed the applications but the business department wants us to recover the content of the messages in the XmitQ. The other QM cannot be brought online again.
So, is there any way to read the messages and their content to a textfile??
Tried mqbrw already but failed as it is doing a get, which is inhibited.
Cheers
Thorsten
P.S. QM is Version 7.5 on Windows |

You will have to GET(ENABLE) the transmission queue. Then you can read the messages.
They won't be of any use until you remove the Header that is added to the message for its transmission to the remote site.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Tricky if (as the OP claims) the QM can't be restarted, which I find implausible.
The transmission queue is expressed as an OS file, it may be possible to reconstruct the payload data with some custom code. Restarting the QM and doing gets is by far and away the easiest solution.

MO71 can strip headers when moving messages.

I'm pondering why applications need to be modified to cause message to go to a local queue vs. a transmission queue. Changing the queue definition from QRemote to QLocal is/was all that we required. Or, is this the 'missed reconfigure' to which you refer?
