Hi,
I'm using tk4- and try to understand the job class definitions in SYS1.JES2PARM(JES2PARM) which read in essence
&STC ...,PERFORM=1
&TSU ...,PERFORM=2
&A ...,PERFORM=4, "Low priority batch"
&B ...,PERFORM=1, "Standard batch"
&C ...,PERFORM=1, "KICKS single thread"
&H ...,PERFORM=3, "Hot Batch"
&S ...,PERFORM=3, "Sysprog"
The PERFORM parameter specified the 'performance group'. This term is mentioned in GC23-0002-0, but unfortunately not really explained because it's a MVS system term, not a JES2 specific term.
I see that CLASS B jobs have a higher priority to get started on an initiator than a CLASS A jobs. But I don't really understand where this is defined.
So I'd very much appreciate if somebody give me some hints on what the full semantics of the PERFORM parameter and the performance groups is and where this is described. Sorry for this plain technical question.
With best regards, Walter
