S0C4 abends after Common Services 15.0 upgrade

Products

Issue/Introduction

After performing the upgrade from CCS release14.1 to release15.0, started seeing CAS9192 messages appear constantly in the syslog. 

We were performing the upgrade without IPL.

We tried running the CAS9 procedure again and it appeared as though the CAS9192 messages stopped, but then we started seeing S0C4 abend when jobs were run

Cause

It was found that the CAS9ATRT module attempted to run the LMP Violation table and abends because it runs beyond its original storage allocation.

This occurs because the new Common Services 15.0 environment was running with PTF SO07952, but the original Common Services 14.1 environment did not have on the equivalent 14.1 PTF SO08031.

These PTFs change the expected length of the violation table. When Common Services 14.1 came up it allocated the file with a length of x'1000', with Common Services 15.0 PTF SO07952, the expected length is x'2000'.   Therefore, due to the mismatch this will prevent the upgrade to r15.0 without an IPL; these abends will occur until next IPL.

Resolution

A system IPL would be required.
