Article ID: 268022

Issue/Introduction
A hyper notice was received from Broadcom for LU10255.
Does this only apply if the ACF2 Access command is in use?
OPTIONS IN EFFECT: ACCESS SUBCMD=DISABLED
Environment
Release : 16.0
Resolution
Generally, it is suggested that all HYPER PTFs should be installed.
PTF LU10255 resolves a problem when calling ACF00RBS - it is not only the access command that calls ACF00RBS - user programs can also call ACF00RBS.
If there are user programs that call ACF00RBS and they use function x'02' (return list of users) - this PTF is needed.
Additional Information
OVERLAY CALLING ACF00RBS TO GET A LIST OF LOGONIDS IN A ROLE
PROBLEM DESCRIPTION:
There is a possibility of an overlay in the subpool specified
in the XRLSUBPL of the XROL parameter list used when calling
the Search Role Group List callable service routine - ACF00RBS.
The ACCESS subcommand makes use of this call when a ROLE is found
on a ruleline and we need the logonids associated with that ROLE.
The overlay can occur if the ROLE found on the ruleline is a GROUP
of ROLEs. If the total number of logonids associated with the
GROUP of ROLEs is over 100 we will have an overlay.
If the overlay happens while running the ACCESS command it will be
in SUBPOOL=0 storage.
SYMPTOMS:
The symptom reported so far has been an overlay of our control
blocks causing an 0c4 in the ACF command processor.
The overlay could be anything within the specified subpool.
IMPACT:
Depends upon what gets overlayed.
