| I've developed my own batch trigger monitor, using MA12 as a reference. It's been running for over 10 years without any problems, so I don't understand the criticism that it's more trouble than it's worth. Aside from that, I have one suggestion. Undoubtedly, whoeve imposed this requirement on you to use MA12 as a mechanism for submitting batch jobs (via Control-M, or whatever), there's a fair chance that you might be asked to support some other task via MA12 in the future. So, my suggestion is to design your batch trigger monitor so that it can "launch" any arbitrary job. I used the Application ID ins a process definition as a key into a table, which then allowed me to submit the job associated with that key. It's pretty straightforward. Beyond that, you can get as fancy as you want, e.g. develop an interface to the batch trigger monitor to do things such as dynamically loading a new table, disable the submission of a particular job, display statistic, and so forth. Good luck. |

Compared to UNIX and Windows, triggering on z/OS is a bit more tricky. There are a variety of ways to launch work on MVS: started task, batch JCL submitted to JES, CICS, IMS. Much simpler on UNIX and Windows where there is really only one way.
Automation software can watch for events such as a message to the op console, or a dataset being created. My favorite is a message to op console.
The triggered app sends a message (WTO macro or equivalent). The content of the message varies by the application queue attributes or process attributes or trigger monitor app.
I suspect that there already exceptions to the rule that Control-M is the only way jobs get launched...
