If your site uses zIIP processors, then you would need to look at those fields in the SMF records as well. I don't know of anywhere that records the number of TCBs in use, although it is possible the value is somewhere in the SMF records.
Also note that zIIP processors can run at higher speeds than your CP engine. zIIP processors can run parallel DB2 tasks so there's another source of parallelism.
Thank you for your thought.
We have zIIP processors, but the Central processor CPU time was higher than the elapsed time.
To check the number of TCBs active I looked at the SMF TYPE 30 records but unable to find a breakup of all the TCBs that were active. It appears type 30 has only a summarised data of all the TCBs. :S No luck here
