Re: How to clear the joblog

Yes, it's easy when the messages are sent to the caller.

However CPI9150 is sent to QTSMGAFT pgm and CPI9151 to QCNSRDDM pgm
that are resent by these IBM modules when they complete.

So they are associated with call stack entries that are no longer
active. That's harder to deal with.

I've tried with different stack counter values, message type, etc.
but these two messages still remain in the job log.

The only way to get at these messages is via the 4-byte Message Key
of the message.

Any other suggestion ?

You could use either the List Job Log Messages (QMHLJOBL) API or the
Open List of Job Log Messages (QGYOLJBL) API. Iterate over the list
from the end removing any unnecessary messages. You'd need to send a
marker message so you could determine when to stop.

You could use the Receive Program Message (QMHRCVPM) API or Remove
Program Message (QMHRMVPM) API (or the corresponding CL commands) to
remove messages by message key. You'd need to know the key and since
you don't have that information available you'd have to guess.
Simplest is probably to send a marker message and save the key before
starting the application process, send another marker message and
save the key at the end of the process, then generate message markers
between those two saved values and attempt to remove a message with
that key. Monitor and handle CPF2410 because not all message keys
will have an associated message.

The message marker is simply a 4-byte hexadecimal value so by mapping
it to a 4-byte integer you can easily increment between the low mark
and high mark.
