Good day,
I have a very simple test environment on a windows box. I have one QM with a local queue and a reciever channel and i have a second QM with a remote queue definition, transmission queue and sender channel. These communicate fine normally.
I am testing a Channel Message exit on the reciever channel. It does the very simple task of changing the persistence on the incoming message.
When the exit is specified for the Channel, the listener does not automatically start the channel when the sender attempts to connect (as it would without the exit specified). However if i manually start the reciever channel (using MQExplorer) the messages flow freely (with the exit doing as it should).
I am trying to understand why specifying the exit prevents the channel from being automatically started and whether this can be rectified.
I did do some searching around the web and forums, but found nothing pertaining to this (though it always seems hard to ask the right question to get the answer you want)
Thanks in advance |

by no means am I an 'exit' specialist, but it does sound like the exit has something to do with it...
what platform are you running on and which version(s) of MQ are involved?
did you develop this exit yourself?
is it working somewhere else?
for starters...

The AMQERR??.LOG file on the RCVR side should contain an error msg detailing why the channel failed to start.

Yep, I use the MS0R security exit and it works. This has something to do with this specific exit. Check the error log on the receive and see if it says anything about paths.
In UNIX, when you create the QMGR the default path stanzas will be added with a '/' at the end of the path and it should not be there. It caused my exits not to start unless I fully qualified the path.

Apologies for my belated response,
I am ashamed to say i think it was a school-boy error on my part. I think i mistakenly had the receiver channel in a Stopped state at random points when testing. If I'm not mistaken the listener wouldn't start the channel from this state. I did check it with and without the exit multiple times and it appeared to only have problems when the exit was in use, but i suspect the sequence of commands i issued each time were the same, resulting in this apparent fault with the exit. coming to it afresh today with clearer thoughts of what I'm doing and i see consistent behavior both with and without the exit and all's well in MQ land
Short Answer, user error.
Thank you for your help and I'm sorry for wasting your time. |
