Hi Mike,
I would recommend running MQ traces on z/OS to get to the bottom of where the converts are actually happening, if you need to know for sure.
Thanks,
Tim

OR ... all of the below, but MB writes the message as ASCII and the CICS application reads with convert and converts to EBCDIC. There can be (and probably are) multiple code page translations happening in this scenario.

Subject: Re: ASCII to EBCDIC Translation
Actually, it's not as likely that MB will be doing a Get With Convert, unless the checkbox on the MQInput node is clicked.
So what will happen is that MB will read the message as ASCII, parse it using the appropriate model into a logical message tree. This converts all of the ASCII data into CCSID 1200. Then MB transforms the logical message tree, and sends it to an MQOutput node (or maybe a CICS request node), which serializes the message tree according to the new model. The new model could indicate that the data is supposed to be in EBCDIC, so this process would turn 1200 into the appropriate EBCDIC code page.
Thank you,

If the MQ Client application is JMS I do believe that JMS could do the convert for the client app before the message got sent down the client channel.

Yes MB is on z/OS, and thanks that makes sense will follow it up.

I take it that MB is on z/OS.

MB is most likely doing an "MQGet with Convert". Hence, the queue manager is doing the data conversion before it is handed to MB.

Hello all, it's me again asking another dumb question.
We have an application that runs on a windows box. It communicates via MQ to a z/OS mainframe running MQ V71. And Message broker V8. The application on windows communicates with the MF via a V7.1 MQ client via a server connection channel.
The broker sits and waits for messages to enter the request queue. Once a message reaches the request queue, the broker reads it and does message transformation and sends it on to cics.
What we are trying to figure out is when the message is converted from ASCII to EBCDIC. The programmer swears that he does not do it at the windows box, and the MQ guy says that these are server connection channels and unlike real sender channels there is no switch to set for data conversion. After speaking with the WMB programmer he says he does nothing special to convert the message from ASCII to EBCDIC. Am I missing something? Where does the conversion take place? Could it be at the CICS program level?
Any help with this question(s) is appreciated.
TIA
Mike.
