Hi Peter,

Hi,
thanks for the responses so far.
The goal is to have the server (an ancient DEC alpha running some sort of SNA

to the z13 which no longer has ESCON.
Going by the CNA8000 doc it claims this is possible, but I'm i
What's strange to me, is that the program used up all the available storage

dynamically adjusting the amount of storage that it needs based on the
available region. After all, if it were of fixed size, then coding 0M wouldn
Do you have access to Application Performance Analyzer (APA) or Strobe (or
FreezeFrame)? If not, can you cut the program down to some kernel that

Also, do you happen to have COBOL V5 or V6 (maybe the trial version)?
There's no "measurement process" per se - I'm reporting the data as indicated
directly from the job log.

ELEVEN MINUTES of CPU time to manage the stack and heap???
Something is very wrong here. It's either a flaw in the measurement process or
something is very wrong in LE, MVS, etc. If it is eleven minutes of heap
management then I would say that is a PMRable problem.
I would be checking my work -
OK, so no useful work was performed in the extra time. The longer elapsed time
correlated with the increase in CPU time, which suggests a loop of some type,
that burns up cycles but contributes nothing to getting the work done. Just
guessing here.

Oh, the elapsed time absolutely changed in a very noticeable way, of course.
12.55 minutes with REGION=0M, 0.60 minutes without any REGION specified. This
is (more-or-less) repeatable at will. But the work being done (number of
records read, processed, written, and the nature of the processing)
How much did the elapsed time change? I find it hard to believe that the job
actually ran 22 x longer and that wasn't notable as a difference.

Thanks! I'm a little reluctant to run a job that already takes 12 CPU-minutes
with RPTSTG(ON), but I may be able to cut the test data back significantly and
still see the relative increase, in which case this may be very useful. I'll

Running both with RPTSTG(ON) may provide insight.

Your installation may have an IEFUSI exit that turns REGION=0M into a much
smaller value, perhaps even smaller than the default with no REGION specified
at all.
Less virtual storage allocated may lead to less I/O buffering and more I/O CPU

This is not true. If an ILLEGAL VALUE clause is specified in the LINKAGE

I agree with the assessment that the incorrect policy was a ticking time bomb.
In general, I highly recommend always using a new policy name for any changes
no matter how trivial. 'New' in this case does not mean never used before,
simply different from the name currently in use.

I believe the justification for Enterprise COBOL supporting the new options for
INITIALIZE is because one of the options for the new ALLOCATE statement is the
"INITIALIZED" clause. And example of this is:
identification division.
program-id. alloinit.
data division.
local-storage section.
I generally do the same, but I do keep a backup policy defined just never
activated, so really the only other way I think this could happen is if a

another, once the policy changes were no longer pending the old or i
