Hi all,

I dont have much experience with UPES earlier. I have a question on that. I have an UPES activity. I am putting values in I/P container of the activity to Upes Q as XML mesage. From there my application program does the work. Now after the work, it should put a message back on Queue saying "WORK DONE" where O/P container grabs it.

The Question i have now is i am triggering my application program when ever an XML message is put on UPES Q. If i put back a message onto the same Q after the work is done, will the application program get invoked again thinking a new message arrived ? Is it good idea to use same Q for getting and putting messages ? or will i need to use some other Q for saying WORK DONE ? How does it work ?

All UPES Reply Messages need to go to EXEXMLINPUTQ. You should actually put to "FMC.FMCGRP.EXE.XML" which is an alias to EXEXMLINPUTQ.

Refer to programming guide -XML Interface for the format of the response message.

Thanks Ratan & anirud for the prompt reply in seconds.

Now will i have to define a Local Q on UPES QM by name "EXEXMLINPUTQ" and put back the message? or is it created default by the UPES ? I am sorry if the question looks silly. Just trying to have idea about UPES.

thanks again

EXEXMLINPUTQ is a queue created by WF on WF QM. It is the queue on which FMCEMAIN listens. All communication to WF happen through that Queue.

If your UPESQ is on a QMGR which is different from workflow QMGR, then in that case yes you will have to do that

For Example:
Workflow server QMGR: FMCQM

UPES QMGR: MYQMGR

Then you have to define a remote Q pointing to the EXEXMLINPUTQ by giving the remote QMGR name RNAME and the transmit Queue. You will also have to define the channels on both side.

Thanks all for the reply.

I am actually using WF QM - FMCQM and putting message on FMC.FMCGRP.EXE.XML. But for checking the Q depth i need to view the Q-EXEXMLINPUTQ as this the actual one and the Q where i am putting message is alias of this. So, every thing going fine. Thanks all for replies again.
