Hi Chris,
There are other ways to do this type of triggering. I'll suggest a simple approach using only FTP.
You could create a text file at the Linux environment with JCL statements to execute a batch job. Then open a FTP session via shell prompt to the mainframe. After authentication issue the FTP sub-command:
quote site filetype=JES
Issue the FTP put command above and then send the text file with the JCL statements.
Your job can be a simple IEFBR14 job so that you can intercept its execution with a CA OPS/MVS message rule and trigger the desired actions. You can also execute directly the action in the job itself if you prefer. If you use simple jobs you can interrogate the jobname for example to know what action to perform in the CA OPS/MVS message rule.
You can use one jobname to start the CICS regions and another one to stop the CICS region.
The Linux users would have to have mainframe credentials and authority to submit jobs.
Regards,
Mario
