Hi . .

I have a small query.
If i have compressed my loadlib, The address of the loads of the programs will be changed in loadlib.

1. How that can be effect usage of that load with respect to the PPT entry.
2. How to update the new address in PPT for all the loads present in loadlib.

Thanks,
Mchanapa

Hello,

When the CICS region(s) recycle, the new addresses should syncronize.

Possibly i am answereing the wrong question?

Hello,

The systems i've worked on do library compression (and some other maintenance) only when the cics regions(s) will be re-cycled. Which is at least every week, if not every 24 hours. The cics regions come down, backups and compressions or whatever is done, and cics brought back up per the schedule.

Don't compress a library that CICS has in use. If a program needs to be loaded, CICS will load whatever's at the disk-address in the PPT and that's probably been rubbished by the compress. In a busy CICS region, you may not even get a chance to NEWCOPY to get the PPT details refreshed.
