I have suffered through damaged HSM control data sets and other
corrupted files, PSF abends, TCP/IP and VTAM issues, RMF problems, JES
problems, systems that won't IPL or crash shortly after IPL, and
dozens of subtle and bizarre behaviors that eventually led to a
discovery of IBM-written programs making assumptions about "things"
being zero: storage, access registers, high halves, you name it. IBM
did not discover these things because they did not run with the TRAPs
enabled.
I just looked back to see the last time I had major issues with z/OS
"choking" with various TRAPs enabled. It was almost exactly two years
ago when I first brought up z/OS 1.8. With the same standard suite of
DIAG traps enabled under z/OS 1.8 that were enabled under z/OS 1.7, I
end up with a completely unstable system where RMF abended, TCP/IP
applications hung, z/OS UNIX processes got canceled, etc.
My emailed comment to Jim Mulder was, "Obviously, there are still many,
many, development organizations within IBM that don't or won't enable a
few simple DIAG TRAPs while developing their code. Obviously, we can't
use them either if our systems fall over when they're enabled. :-( "
I opened the following PMRs to address the new failures.
Act Record Customer ID Sev Resp Updated Status Abstract

The worst of these turned out to be an error in RSM, probably exposed by
CsvRentProtect, fixed by APAR OA19409.

I know that Marna Walle has been a great help in getting more IBM
testing organizations to use various TRAPs. The last time we exchanged
notes about what she was recommending, IgvInitGetmain was definitely
*not* on her list!
I was wrong about this. Marna has two lists she sens to Poughkeepsie
testing organizations: a "minimum" list, which must always be present,
and a "recommended" list, a superset of the minimum list, with settings
are that "good, but difficult to keep on". IgvInitGetmain is on her
"recommended" list. You go, Girl! :-)
