On distributed the user name is transcoded to upper case when it is sent out, and back to lower case when it is received. If the channel has a msg exit, neither of these is done. There was a bug in an early version of v6 where the receiver erroneously thought that a msg exit was in use, and so did not transcode the name back to lower case. This was fixed in APAR IY81714, released in 6.0.2.0.

This has not been my experience.

A lower-case userid in the MQMD arrives on WMQ z/OS in lower-case.


Huh. I just tested it here. Windows and Linux MQ 6.0.2.3 to z/OS MQ 6.0. If the message arrives on the mainframe, its upper case, if it arrives on distributed, its lowercase. No message exits in place.

Thanks for that APAR # Nigel. That was the problem I was thinking about that caused us to define the UserID in UPPERCASE as a work around.
