RE: RPG IV pgm dump -- RPG400-L

I don't believe the IBM-shipped default is to create non-observable program
objects.  Mark, could you be more specific on that?

I agree on making all apps observable.  To my knowledge, there is absolutely
no performance impact - please correct me if I'm wrong on that.  Note,
however, that with OPTIMIZE(*FULL), "Optimization which generates the most
efficient code. Translation time is the longest. User variables may not be
modified but may be displayed, although the presented values may not be the
current values." - Might this impact what gets dumped as well?

That said, yes, program objects gain size as you increase observability
(question: Is this the DBGVIEW parameter on the CRTBNDRPG command?)  Usually,
though, your data takes up the mass majority of your available DASD.  Whether
having observability or not having it, should not impact your DASD utilization
to any meaningful degree.  If it does, I'd venture to say you're way
undersized on DASD.

FWIW, here's my thinking on the subject - will "saustad" be able to recreate
the problem once he recompiles the program to have observability?  Perhaps,
and hopefully he will be able to.  Sometimes, though, it may be too late to
add back the observability.  And, even if s/he can recreate the problem, how
much time will have been lost because the program did not have observability
in the first place?  Time = Money.

Your program is not observable; saves room and is the default, but DASD is
cheap, so
you will have to recompile so it is observable, then let is abend again and
dump,
then you will see your variables.  By default here we make all ILE
observable just for
this reason, the space savings IMHO is nominal, performance "could" be a
hit, I am not
a bare metal techo weenie though, but from an overall time saver, I feel you
are better
off just making them observable to begin with, why, because no one is
perfect, and we
will all miss the size at some point in time, or someone else will put some
erroneous
data in "our" files.

Subject: RPG IV pgm dump


We had an RPG IV pgm abend this morning with the following error:  The
target for a numeric operation is too small to hold the result.  We
understand this msg.  But when we looked at the dump, there is no field
information.  At the end of the dump is the following stmt:  Dump
terminated because variable data not available.  Does anybody have any idea
what this means?  Thanks for any help.
