Re: What are STC, JOB and TSU?
Thank you every one very much for your valuable input. From all I've read, the answer really wasn't very straightforward. But the two experts SDSF and MXG call it Task Type, but not sure about IOF, I got bored looking for it. And in some of my own Rexx code I just found there were five types used: JOB, SUB, STC, TSU, OTH. There wasn't a title (like Task Type) but I did assign them to variables starting ASCB. (Personally with this particular work I only have JOB, STC, TSU). John, the Unix stuff is so super cool like you said, but for me in this very particular case I am working on when I see a TSO user ID racking up CPU time as an STC, with my inside information I now know exactly what is going on. They are spawned client/server sessions.

I would probably say something like: On z/OS there are four classifications of address spaces. Three of them are controlled by the Job Entry Subsystem (JES), and the type can be derived from the JES job id. Those three types are J, S, and T; for JOB (batch work), STC (started task), and TSU (TSO users) respectively. The fourth type of address space is called a system address space. This type of address space runs outside of the control of the JES and so, normally, does do any SPOOL activity. This type of address space can be started with an operator command by adding the SUB=MSTR parameter to the START. It can also be created programmatically using internal facilities such as the ASCRE system service. Since they run outside the control of JES, they do not normally have a JES job id. There are facilities whereby such an address space can register itself with JES, at which time it is given an STC job id. I.e. substitute address space for blank. I am fairly sure that when the CPU is not in a WAIT, that there is a value in the PSAAOLD which, IMO, makes that ASID the current ASID. Hum, is this true? The only thing I'm not sure of is a global SRB. Can PSAAOLD be zero while a global SRB is running? The STO control register has to have _something_ valid in it unless you are somehow running DAT OFF. Which is _extremely_ rare in z/OS. Depending on the level of detail you want, you might not want to even mention the system address space in such detail. But you might want to mention it briefly because such will show up in SDSF, but without a JES assigned id. I also don't know if you want to inject anything about the weird and wonderful way that z/OS UNIX works. I.e. a batch job, with a JOBn assigned to it, can be a UNIX process. But a child process, created with fork()/spawn(), runs as a separate STCn type address space (ignoring local spawn(), of course). But that may be too much information. I couldn't even make it clear to other experienced sysprogs (one of whom had been a vendor developer) very well.

Re: What are STC, JOB and TSU?
A different view: From my first MVS courses: there a 3 ways to create an address space: Start, Logon and Mount. Mount is a special case, not seen often. Logon creates a TSO address space, with a T* jobid. Start creates an STC address space, with a S* jobid, which can nowadays also be created by more ways. One of the STCs you can start is the INIT STC, which runs the initiator task, which gets a job from JES and runs it. It then transforms its address space to a J* jobid.

Sent by:IBM Mainframe Discussion List IBM-MAIN@LISTSERV.UA.EDU Hi group, I'm having a bit of a problem identifying what classification those names are. I know what started tasks and TSO users and batch jobs are, but if I were to say: On MVS there are three blank (or three types of blank) which can be derived from the JES job ID. J or JOB means batch, S or STC means started task and T or TSU means a TSO user. (My best guess was 'job type') Are there more than these three? I'm simply writing some high-level documentation, and I've already used up my quota of writing thingy when I don't know what it is. MVS has a lot of thingies. Thanks for your help.

AW: Re: What are STC, JOB and TSU?
Don't forget ASCH and OMVS. And for 7-digit Ids expect to see eg J1234567. I have not seen an APPC initiator in action, so I can't remember whether they will show as Annn or as S but there definitely is no OMVS type of address space in the sense Lindy was asking. Each of STC, TSU and JOB can run UNIX work inside, but only fork() and non-local spawn() will create OMVS type of WLM work units, and they all run as STC in BPXAS STC address spaces. -- Peter Hunkeler -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
