Hello,

More cpu time than what?

If you post what you read, it may help us help you.

If this is a recent occurrance, it is probably because some code has been changed/added that uses more resources. It may also be related to a higher volume of data or a change in the way the data is referenced.

Changing you MAXTASK's parameter could have an adverse affect on the region and make things worse.

Please speak with your CICS System Programmer regarding your increased CPU usage. Perhaps he/she could run some diagnostics (IE: STROBE) and/or utilize their 3rd-Party Monitor (TMON, Omegamon, etc) to try and pinpoint the culprit.

Regards,

Hi Vidhyag

You can check in your organization which all performance tracking/improvement tools are being used . You can then run this tool against your CICS region or transaction and see what is causing the delay and change the code accordingly.

STROBES by COMPUWARE is one of such tools.

Guys
If the shop is not having any performance monitoring tool, from where one can start to resolve the above issue?
Will CICS job log can lead to some inferences.

Thanks

performance tuning is normally the responsibility of your CICS
Tech Support group.

Why not discuss with them ?

Not to worry. . . However, as i asked before "more than what/higher than what"? Is there some statistic that shows more/higher cpu being used or is this a feeling someone has?

The first step in trouble-shooting is to be sure the "trouble" is identified.

So far, a clear definition of what needs to be improved has not been posted.

If you find something you intend to try or quote from, suggest you make a copy on your local hard drive or at least a link to it (making a copy is better as links sometimes go away).

To repeat:

Suggest you investigate to see if any of this might be what has happened.
