Yes <snip> > Q2. When the SRBs are being executed, the ASSBPHTM of address space > 'A' = CPU time consumed by S1 + S2 + S3. Because PHTM is for all types > of SRBs. Is this the correct understanding? </snip> Maybe, maybe not.. The first sentence is true if you have described all of the work going on related to this address space. The second is incomplete, since it does not mention enclave tasks or work running in this space but with a different home. If you choose to say that there is no such work in this case, then the sentence is correct for that case. <snip> > Q3. So the delta between PHTM and ASST would always result in the pure enclave > SRB CPU time of that address space? </snip> No. ASSBASST's comment: Additional SRB Service Time. CPU time is accumulated here for this address space's Preemptable SRBs and for Client Related SRBs for which this address space is the client. <<this is to be clarified from "Preemptable SRBs" to "non-Enclave Preemptable SRBs".>> ASSBPHTM's comment: Preemptable-class Time. The CPU time for all types of preemptable SRBs (PSRB, CRSRB, ESRB) executing with this address space as their home space and preemptable tasks <<to muddy the waters, I screwed up the "task" part of the comment in z/OS 2.4. It will get corrected in the data areas book.>> The commentary on the fields should lead you to understand that in general the answer is "no" (possibly it's correct for the specific scenario you mention if there are no other relevant work units involved). You cannot in general ignore the phrase "with this address space as their home space" or the phrase "and preemptable tasks".
