If the OP is willing to call an interface instead, the use ERBSMFI and get SMF79-1 records and look at the values in R791TAS.
CHKTRID is a good place to start if you are trying to work this out from control blocks yourself, but there are a few nuances to consider (assuming you have the ASCB address for the ASID) : (o) If ASCBJBNI is non-zero, you need to get the CSCB from CHCSCBP (based CHNAME on ASCBJBNI) (o) If ASCBJBNI is zero, use ASCBCSCB (o) If CHJOBID, then you might have a JOB, but it will be STC if ASCBJBNI=0 (o) CHTSID = TSU (o) Otherwise you have an STC, but then you need to identity ASCH, OMVS and INITs from jobnames If you then want to accurately populate fields like “STEPNAME” and “PROCSTEP” you need to be careful as they can come from different places depending on the logic above. It is a bit messy TBH. Also bear in mind that ASID(0001) is called “SYSLOG” 😊 Rob Scott Rocket Software From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Binyamin Dissen Sent: Friday, December 8, 2023 11:57 AM To: [email protected] Subject: Re: Find the ASID type?
