I am a beginner in learing WebSphere MQ and CICS.
As some books have said, "To trigger the CICS transaction, WebSphere MQ generates a trigger message and puts it on to the initiation queue. A trigger monitor, will run in CICS to process this message and then start the appropriate transaction."

I am so confused with the "appropriate transaction". For example, if a rexx script sends a request and the trigger monitor wants to process this message, which "appropriate transaction" will begin ?
At first I think it will be the transaction CECI. But after I check the CICS Infomation Center, I find out that the CECI does not have a command that can be used to process the rexx script.
Therefore, could you please tell me, if triggered, which transaction in CICS will be beginned to process the rexx ?

Thanks very much.
(Sorry for my poor English)

Hello,

Over time, with practice, the English will improve

which transaction in CICS will be beginned to process the rexx

I believe you have a considerable bit of misunderstanding. . . REXX is run in tso/ispf or batch - i've not seen rexx run in cics.

If you use websphere to trigger a transaction, part of the process is the specification of which transaction to invoke.

Thanks for your reply.
I am getting a bit more understanding with your help.

Please allow me for asking one more question.
If the trigger monitor that I use is the "WebSphere MQ-supplied trigger monitor for CICS",
after I use a rexx program to send a request, which CICS transaction will be triggered to process the request ?
Does there exist a way to find this CICS transaction ?

Thank you.

Hello,

From earlier:

i've not seen rexx run in cics.

Since this post, i've learned that rexx can be run in cics, but is not yet so common. . . (Thanks Enrico).

after I use a rexx program to send a request, which CICS transaction will be triggered to process the request ?

I'm still not sure if this is how the process will work. . .
Does websphere not issue the request to cics (where the rexx is run)? I'm not sure what request might be sent from rexx to websphere.

See if this might have something useful:

This is not something any of my clients are doing to day, so i'll be learning right along with you
The bad news is that with the pieces not available, i'll not be able to experiment. . .

Hello,

Did someone find the answer?

Thanks.

An answer can not be given as far as I can see. The question itself is garbeled. He talks about MQ sending a message that triggers a transaction. Then he talks about Rexx and which transaction is triggered. Beside that, isn't this a site dependent question? What transaction is triggered depends on the definitions in the shop. So, I really do not know how anyone outside of the shop can help with this.
