Hello All,
Very quick question about unused entries in CICS. There are hundreds of unused entries (PPT, FCT, PCT) found in CICs. These are in numerous groups that are NOT in the startup lists. Are there benefits that can be had by removing/deleting them from the CSD?


Thank you,

danteb

IMUO

anytime you can reduce the size of 'something' that is to be processed,
reduces the time to process.

I would back-up before I deleted anything.


both the above are just general rules, not specific to cics or any application.

Be careful. The RECORDSIZE in the CSD/IDCAMS definition beginning with CICS/TS version/release 3.1 (and perhaps version/release 4.1 as well) is now (200 2000), which is different from its predecessors.

Issue a LISTCAT of the target CSD before you do anything to ensure that the proper characteristics for the backup DELETE/DEFINE are correct.

Regards,
