Hi,

In one production CICS region we are facing the following issue regularly.

Because of one transaction(XXXX) the region is getting hunged we analysed on that then we came to know the Program which is associated with that transaction having getmain failure. We discussed with the application support they said from thier side they cant able to change anything. they are asking as anyother suggestion to avoid this.

Then we decided to change the DSA limit for that region or Region parameter in the CICS Region procedure. But we are in a suitation to do not change because of storage availability.

Please can anyone suggest me to overcome this issue and what can be done from application side for that program or from CICS System support end

If a program is causing the CICS region to hang, doesn't it make more sense to fix the program instead of modifying the CICS region parameters?

How about NOSUSPEND option in GETMAIN

NOSUSPEND
prevents CICS from suspending the task if no storage is available, and
causes it to issue the NOSTG condition instead.

Note, however, that if a HANDLE CONDITION for NOSTG is active when the
command is executed, control is passed to the user label supplied in
the HANDLE CONDITION. This takes precedence over the NOSUSPEND option
but is, of course, negated by either NOHANDLE or RESP.

Thanks,
Ravikumar.

What sizes are we talking about here? How big is the getmain that the program is requesting? I would demand that the program be changed if it is hanging my CICS region, and management should support you.

It would be nice to know what is happening. We like to help but also like to hear what the solution was. I would like to know what sizes we are talking about. Very often batch type programming (and storage demanding) is done in CICS, like loading tables into storage, etc. Or the programs themselves are way to large.
