Sometimes JES2 will not terminate
If for whatever reason JES2 does not want to shut down, and probably the following message shows up:
$HASP000 JES2 NOT DORMANT -- SYSTEM NOW DRAINING
The reason for this might vary. It could be that (for example) a printer still has data to process.
Try to gather more information with:
/$DU
Then find out which device is trying to drain and cancel this process. e.g.
/$C PRINTER3
Now we should be able to finish JES2.
/$PJES2
Force JES2 down (sometimes needed)
When all else fails we force JES2 to ABEND with the following command:
/$PJES2,ABEND
Now a numbered request will appear:
*nn $HASP098 ENTER TERMINATION OPTION
and we answer:
/R 01,PURGE
that should do the trick…
