Scott Barry's Share Session 24421 in Phoenix this Spring provides a good analysis of zEDC analysis, including this list of relevant SMF records.
Here are the various SMF/DCOLLECT record references: - RMF 74 subtype 9 - SMF type 14/15 - SMF type 30, zEDC data-section - SMF type 23 (for SMF Logstreams and zEDC compression) - SMF type 88 (again, for SMF Logstreams / compression) - DCOLLECT – record types “D” (Dataset/VTOC), “M” (Migrated) and “B” (Backup).

I can't remember if I posted this before, but it's come up again so I'm asking. Is there any way, short of running a job with SMS turning compression, and running it a different time with compression off, to measure the CPU time used by SMS compression for a dataset? I know I can get zEDC CPU savings estimates from zBNA and I'm pursuing that path too, but it seems to me it's something that ought to be reported; especially since recent versions of z/OS have zEDC measurements reported to SMF. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
