I connected to an intermediate Linux Queue Manager that then forwarded the messages with QM to QM channels to the z/OS QM. The SENDER channel did not have conversion turned on. I did turn that on for one of my test cases to see what results I got if the messages was converted before it arrived on the MF QM as described in one of my posts in this thread, but that was just an expiriment and only doen for one test case.

No. Well, there is a fine piece of exit called MQAUSX on the client channel doing security exit stuff, but no exit anywhere doing conversion stuff.

How would convert on MQGET work when there is an MQIIH header? Say what?

Review the first few posts in this thread, on the first page, and you can see its the RCVR channel that does the convert, without any special setting being enabled or even possible, when the message is bound for an OTMA bridge queue, and it deals with the MQIIH header correctly.

You seem to be intimating that something like WTX maps are needed to construct msgs to go to IMS OTMA for DP. I'm not too familar with DP, so I don't know how flexible it is about building message types other than XML.
|
No, we just happened to be using WTX to create the message which was another peice of code being developed by another person which added variables and fun to the mix.

With a bit more precision, WMQ headers are converted (if necessary) on message arrival at the destination qmgr. Your application data payload conversion will be driven by CONVERT(YES) at the sender end, or by MQGMO_CONVERT at the receiver end.

Bruce, what would be specifying MQGMO_CONVERT in this scenario on the receiving side?
Not the IMS app, it doesn't know about MQ.
Not the OTMA bridge, the manuals say the IMS Bridge does not convert.
http://www-01.ibm.com/support/knowledgecenter/#!/SSFKSJ_7.0.1/com.ibm.mq.csqzal.doc/fg15970_.htm
Not the RCVR chanel, its not doing an MQGET from an MQ queue.
Seems like the RCVR channel is taking it upon itself to convert the message coming across the network link if the RCVR channel sees the message is destined for a queue being read by the OTMA bridge.
