SMF type 30 has a lot more granularity than the message. If you submit an RFE, I advise that you not ask to have all of those data in the message. OTOH, a ew more fileds wouldn't hurt.

I don't have MXG but I am super familiar with SMF concepts, reading the SMF documentation, "decoding" SMF triplets and so forth. I see the following: 12 C SMF30ICU 4 binary Initiator CPU time under the task control block (TCB), in hundredths of a second. This field is set at step termination. SMF30ICU = SMF30ICU_STEP_INIT (for this step) + SMF30ICU_STEP_TERM (from the previous step) Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Allan Staller Sent: Tuesday, August 6, 2019 3:13 PM To: [email protected] Subject: Re: CPU time cost of dynamic allocation SMF type 30's contain the start and end time of the allocation process for the initiator. I cannot specifically recall whether the CPU time for this process is broken out into a specific bucket, or can be calculated. I you have MXG, Barry Merrill has a lot of doc in this area. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Charles Mills Sent: Tuesday, August 6, 2019 2:02 PM To: [email protected] Subject: Re: CPU time cost of dynamic allocation Can you please clarify? Your first sentence seems to say that SVC 99 (or do you mean Initiator) CPU time is in the SMF 30? Can you be more specific? Your last sentence seems to say the opposite? Or ... ? Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Allan Staller Sent: Tuesday, August 6, 2019 12:54 PM To: [email protected] Subject: Re: CPU time cost of dynamic allocation This allocation time can be calculated from SMF type 30. I am sure time is tracked. I am not sure the associated CPU is tracked. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Paul Gilmartin Sent: Tuesday, August 6, 2019 11:45 AM To: [email protected] Subject: Re: CPU time cost of dynamic allocation On Tue, 6 Aug 2019 12:25:05 -0400, Charles Mills wrote: > >OTOH I have an IEFBR14 batch job on the same machine that allocates 15 >temporary datasets in JCL.
