Thanks for all of your responses,, we going to use a region size of 1024M
for most of our batch,, the exception being the SAS which or sysprogs want
us to leave running with 0M.
I think we still may be at risk, but it's not my call.

Hi All,
We are having discisisons regarding an optimal region size for our
standard batch processing.
Currently, we use region=0M for all of our batch jobs without any noticeable
problems.
Is this subparm useful anymore? it would appear that our system does not
care too much, but i am concerned
our sysprogs discourage (prevent?) 0M on the belief (fact?) that if such a
job were to run-away and consume all available memoryon its way to
ebending, there would be no room to set up abend-related control blocks in
memory when it did abend - thus we are constrained to use 2047M

When I was in support many years ago, many times customers would call asking
us about an S40D or S0DC abends - it just went away! (For the peanut
gallery, the problem is that there is no more left in below-the-line private
to acquire LSQA for the RTM control blocks.)
I've lost track of the
've lost track of the times I've told people why 0M is a bad idea for a
server-type program, and in general is a bad idea.
IBM has shipped 0M for 'server-types', for years.
VTAM, NETVIEW, IMS, DB2, MQ-Series, to name a few.
I don't have a problem with that.
Where I have a problem is with
I have a SAF call in IEFUSI, you get over 256M if you DESERVE it.
I think you can address the under 16M vs. 0M limit in IEFUSI as well, I
think you could set the region size to a suitable value less than
GDAPVTSZ.

IMHO it's like lack of fuse in a circuit. Fuse is not needed ...unless
