system event trigger whenever a source file member is updated

["Dan Bale" <dbale@xxxxxxxxx>]

Am looking for a system event trigger of some sort that would tell an
application that a file's member has just been updated, deleted, or added.
All physical files, all members.  Specifically, all *source* physical files.
I would be happy to know this at the file level, i.e., a "member event" has
just occurred on file DJBLIB/QSRC; then my app would interrogate the file to
see which member(s) have just changed, or been deleted or added.

The idea behind all this is to utilize a WRKMBRPDM type tool (which I've
built and named FSM) that isn't limited to showing members for a single
library.

Currently, I run:
  DSPFD FILE(*ALL/*ALL) TYPE(*MBR) OUTPUT(*OUTFILE) FILEATR(*PF)
each night, and my FSM derives its member list from that.  This is
sufficient 99% of the time, but the other 1% has been known to burn me here
and there, as members get created, deleted, moved, etc.

Had high hopes pinned on journaling the QADBXREF file but, unfortunately,
the change timestamp does not get updated for any member event.  I could
still journal it to determine when source files are added or deleted.

There's just gotta be a system-maintained member-based file somewhere.  A
user-space maybe?  How does DSPFD TYPE(*MBR) gather its data?  I would be
willing to utilize an "unsupported" reference.

Leif, do you have something on this in your e-book?

TIA,
