Hi Craig, excellent contributions. Thanks for everything.
I'll tell you a situation that we are observing in our DB2 for z/OS V12 FL510.
We have a buffer pool with PGFIX YES with FRAME SIZE 2G and 1M for a few months.
After recycling the db2 on Sunday nights, an improvement in performance is observed on Mondays during the online period. The next day after the batch is a normal performance, kept until the next recycle.
Where do you recommend I look for the reason for this behavior?
Thank you in advance
