OA27291 is closed with some good information included in the APAR text.
Hopefully, people understand that this APAR doesn't "fix" the failing
programs. They still make erroneous assumptions about the initial
contents of the storage they acquire and are at risk of failing with our
without UseZosV1R9Rules(Yes) coded. And, there are also other programs
that make erroneous assumptions about initial storage contents that
still seem to work most of the time, even with the new z/OS 1.10 VSM
behaviors.
The ONLY way to find all of the programs that make erroneous assumptions
about the initial contents of acquired storage is to test with the
IgvInitGetmain DIAG trap enabled. I repeat, it's the ONLY way! But, so
far IBM has not documented that facility. IMHO, APAR OA27291 provided an
appropriate opportunity for them to do so. Unfortunately, that
opportunity was missed. :-(
So, we're no further along with this than we were before. There are
hundreds, maybe even thousands, of programs making erroneous assumptions
about the initial contents of acquired storage. These programs are coded
improperly and are exposed to what might appear to be "spurious" or
"unrepeatable" abends. Those that are APF authorized might even
represent potential exposures to the system! And, yet there is no
DOCUMENTED or SUPPORTED way for IBM's customers to find and fix these
erroneous programs! >:o
