Hi,

Can we bring down and bring up a CICS region thru JCL? Can someone help with one?

Thanks,
Prasanna

IIRC, you can use IEBGENER, specifying a JES Modify command, which issues a CEMT PERFORM SHUT or CEMT PERFORM SHUT IMM against the target CICS region.

As far as starting the region back up, the region is probably an MVS Started Task, in which case, it would be an /S "region-name" Console command.

Other members may have different solutions.

Do you have any type of Automation package?

It's much easier with a package like this....

This is pretty much how our shop handles shut downs. We schedule the job and use the EXCI to issue CEMT P SHUT.

As Bill indicates, the answer is ... it depends. Possibly yes, depending upon your site. IIRC, there is a RACF facility to allow batch jobs to issue console commands; if you have this authority then you can certainly shut down and bring up a CICS region from a batch job.

Whether or not that SHOULD be done is another question entirely -- depending upon the site and the specifics of the region, it may be possible but not recommended to do this. Follow your site's standards and procedures, and you'll have many fewer explanations to management over time.
