ACF2/CICS users appear to be timing out from CICS soon after a logon, even though they are active.

Issue/Introduction

Users logging on to CICS appear to be timed out by ACF2 within a few IDLE cycles, even though they are active.  Recently PTF SO10542 was applied on that system.

Environment

Release : 16.0

Component : CA ACF2 for z/OS

Cause

PTF SO10542 was PE'd as a fix in error .  The PTF was causing "orphaned" KTRT's.  The orphaned KTRT's are happening from logons generated from a signon without password, such as with ATTACHSEC=IDENTIFY to a remote CICS region.  Some of the KTRT's may have been referenced in error by the TIMEOUT function, resulting in a user incorrectly being timed out and disconnected from the CICS region even though they just became active.

Resolution

Hyper PTF SO12929 resolves the problem:

Title: CICS: ACEE STORAGE LEAK; NO PW SIGNON FAILURE W/SO10542

PROBLEM DESCRIPTION:                                                       
With ACF2 CICS PTF SO10542 installed signons without password              
may either fail or create an orphaned SP255 ACEE.                          
This may result in a storage shortage in the CICS region.
