That has been pure guessing; I have no clue how sampling programs get to know
what happens

I find it hard to believe that a sampling program looks at "RBOPSW" of
something that is not running.
As to the question/answer about disablement: while the application itself
is not disabled,

MA-Tune has it right, it was me who was wrong: I thought IEAVEPS1 is POST, and
therfore I would not

Indeed! Now it all seems to makes more sense: The TCB is being PAUSEd until DB2
finishes its work. MA-Tune finds the TCB not dispatched and looks at the OPSW

I doubt. This is a plain normal COBOL
