We run GDDR and OPS/MVS, we current have it set at IRXANCHR ENTRYNUM=2000 since
last April for all tasks. We have not seen any adverse effect.

Subject: Re: IRXANCHR - Number of environments
We have been running with 400 specified since sometime back in '03 with no
problems until yesterday. We are a GDPS and SA/390 shop so there can be a
lot of autotasks running during some configurations changes. Yesterday we
got message
CNM416I REXX INTERPRETER ENVIRONMENT INITIALIZATION FAILED FOR TASK
AUTBAT26, RETURN CODE = 20, REASON CODE = 24
during a reconfig we were running that caused some minor problems for a
while. IBM has recommended that we up IRXANCHR to avoid this in the future.
One comment was It is not uncommon for customers
to define 2000 or 3000 rexx environments on the system, and this serves
not only netview/sa/gdps but other applications that use rexx.
Q1: Is anyone out there running IRXANCHR in that range?
Q2: If the default IRXANCHR is that high, is there any significant resource
(i.e, storage, etc.) being wasted on the system as a whole or per address space?
Q3: Does anyone run a default IRXANCHR with one value and a customized
IRXANCHR with a higher value that is STEPLIB'd to GDPS, SA/390, NetView
tasks?
