RE: API to retrieve messages from history log

When you do the dsplog you can hit F10 and select only certain message 
id's.  This should help your process run faster.

RE: API to retrieve messages from history log






Thanks Tom,

I just looked in the QHST* files and they look scarier than the spool 
file.  This to be a stand alone process to be run daily so reading through 
the spool file shouldn't be too bad.  If I first check against the message 
ID and the scan the text of the appropriate messages I should be fine.

Thanks again to everyone for their ideas.

Mike.

Mike:

Your major problem is that the "messages" you're after probably will _not_ 
be in the QHST message queue. Most likely they'll be in one of the QHSTxxx 
physical files in QSYS, and there they won't be "messages" but just 
records. No "API" needed, just open the files and read them.

The secondary problem is flushing messages that _might_ still be in the 
QHST message queue out to the PFs. I vaguely recall that a technique 
exists for this, but I'm no longer certain what it was. Maybe something 
like execution of DSPLOG caused the flush, but not sure. Perhaps this will 
jog memories from someone else, perhaps experimentation is in order, or 
perhaps it's documented.
