RE: How to properly Ending a background program

Can you provide a little detail on why a signal handler is better than
%SHTDN or provide some links so I can read up on it myself? I've always
used %SHTDN so your reference to it being "clunky" made me go HUH?

Shutting things down with *CNTRLD will also send a SIGTERM signal to the
job, so your program could use a signal handler (vs. the very clunky %SHTDN
BIF) to catch the condition and end immediately.

If the sleeping loop is in the RPGLE, you can use %SHTDN. That also
trips on the same conditions as RTVJOBA.

Just remember when you are shutting things down (PWRDWNSYS, ENDJOB,
ENDSBS,
etc.) make sure you end it *CNTRLD instead of *IMMED and allow it
enough time for it to react and do whatever needs to be done before
ending. For example, if the job sleeps for 10 minutes and you end it
*CNTRLD with a 5 minute window, it might not wake in time to exit

gracefully.
