Late to the party, I'm wondering what SMF 30 says. Cheers, Martin

Thanks for that insight. It always helps to see the source of information that is presented. Maybe I can produce a small TSO utility to find this data. But it looks like it might have to a tiny bit APF authorised to get to the necessary information. (I assume you meant to type ASXBSENV rather than ASSBSENV. I think the ASXBUSER field would probably be sufficient.)

As far as I am aware, there is no definitive field in common storage that contains the userid associated with an address space regardless of how the job entered the system. In a dump, there might be some mileage in examining OUCBUSRD if there is no JSAB, or sniff the ACEE from ASSBSENV (or even run the TCB tree and process any non-zero TCBSENVs).

The RACF address space runs under a user id. In fact nearly all work after the initialisation of SAF (which happens very soon after MSI) will run under a user id. Even initiators start work under a user id (although they subsequently lose that id). In addition, any started task that is submitted using SUB=MSTR, (such as LLA, VLF ICSF and others) will start under a user id. Yet all these address spaces do NOT show a user id in SDSF DA or using the MVS DISPLAY command. Lennie Dymoke-Bradshaw https://rsclweb.com < https://rsclweb.com > 'Dance like no one is watching.

The column 'Owner' shows the user id associated with the address space. However, for those address spaces which are subsystems or which are started under the master subsystem, the user id is not shown. If I display address spaces using the MVS display command D A,<name> I get a similar result. The user id of the address space is not shown. While I am aware, this has been the case for some time, I am confused as to why this is. For SDSF I had thought it was simply that the id was extracted from JES2 and of course the subsystems have no such JES2 control blocks. But the MVS display command does not have that restriction. Does anyone have any insight? Does anyone know how to determine the user id of these address spaces using commands?
