Re: Retrieving active controlling subsystem

["Mark S. Waterbury" <mark.s.waterbury@xxxxxxx>]

Hi, Mark:

I issued a "WRKSBSJOB QCTL" on one of my machines, and
I can see in the "controlling" subsystem a job named QSYSSCD
running under user QPGMR and calling program QEZSCNEP ...

I think this is something to do with the OS/400 job scheduler
that comes with OS/400 (WRKJOBSCDE and friends ...)

I don't see that job name or program active in any of the other
subsystems ...

So, perhaps this might be one way you can 'tell' if this is in fact
the "controlling" subsystem, by looking to see if this job is active
in that subsystem?

Regards,

Mark S. Waterbury
