Jay, You may want to check what TRACE classes your DBA are using. There are a few that can generate copious amounts of data into SMF, but they may only need to be captured for short periods of time.

For some reason - the word "overkill" came to mind. So I decided to conduct "Operation Overkill". 36 MAN* datasets per LPAR... MAN0 - MANZ... 3337 cylinders per MAN*. 24 hourly jobs to MOD the DUMPXY contents to virtual tape. ( First job each day is DISP=NEW just to keep things pretty ) The following day we have a problem. IEFU29 isseued "I SMF" every 3 minutes. Here's what 1 of the 2 LPARs looked like... 0080 P-SYS1.FJI0.MAN0 SMFDB2 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN1 SMFDB3 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN2 SMFDB2 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN3 SMFDB3 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN4 SMFDB2 100050 91 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN5 SMFDB3 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN6 SMFDB2 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN7 SMFDB3 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN8 SMFDB2 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MAN9 SMFDB3 100050 100 DUMP REQUIRED 0080 S-SYS1.FJI0.MANA SMFDB2 100050 24 DUMP REQUIRED 0080 S-SYS1.FJI0.MANB SMFDB3 100050 87 ACTIVE 0080 S-SYS1.FJI0.MANC SMFDB2 100050 0 ALTERNATE 0080 S-SYS1.FJI0.MAND SMFDB3 100050 0 ALTERNATE 0080 S-SYS1.FJI0.MANE SMFDB2 100050 0 ALTERNATE 0080 S-SYS1.FJI0.MANF SMFDB3 100050 0 ALTERNATE Hourly copy job coundn't get enough CPU to copy out the data to virtual tape. The solution in this case was stopping type 100 - 102 collection. Changing the Workload Management Class of the copy job to STCHI. The DUMPXY process caught up with itself in about 20 minutes.
