Thanks. We've already looked at this, and make some use of it in the batch world. However what I'm looking at that is attractive is the feature of the MQ0L support pack that attempts to regulate the number of triggered processes servicing a particular queue. I note that Support Pack MA1J provides the source of the default trigger monitor program CSKTASK, but this is also provided in C source.
My problem isn't lack of ability working with C, but rather with the lack of a suitable compiler on our system. The only C compiler that I'm aware of that we have is the one that ships with the USS side of the operating system, and I'm not aware that CICS is capable of executing these programs natively. We don't have the C/370 compiler for z/OS.
If I were to undertake such an endeavor as to rewrite the code provided in MA0L, I'd probably do it in Cobol, as more people in my shop would be able to support it after the fact. We've had a triggered MQ Bridge like function in place for some years, and the volume has grown to the point where the overhead of generating trigger messages and managing the number of service processes via CMXT is now becoming unwieldy. I've looked modifying our MQ Bridge program to become self regulating, but have determined that it's probably better to regulate this external of the MQ Bridge itself. And to anticipate questions regarding our reasons for not using the IBM supplied Bridge program, we wrote ours before IBM released theirs, and it has some imbedded 'special functions' that if I had it to do over again, I'd not implement and point people towards IBM's offering. That's all water under the bridge now...

Look at MA12.

The MA0L support pack implements a trigger monitor that does just about exactly what I need to do. The only problem is that it's written in C and intended to run on Windows or Unix variants, and I'm looking for this functionality to be run as a CICS based trigger monitor on z/OS. Before I go off and re-invent the wheel, I thought I'd query to find out if anyone has already done this in a more traditional z/OS based language such as Cobol or ASM?
