Issue/Introduction

We received the following on a XCOM transfer in our development LPAR
XCOMA 00000014 *ICH409I 0C7-000 ABEND DURING RACINIT PROCESSING 
XCOMA 00000010 CCSR010E XCOMSTSK S0C7 at 0A62B504 LMOD IGC0013{ CSECT N/A +N 

The LPAR was recently upgraded to z/OS 2.3.

Environment

IBM z/OS 2.3

Cause

The abend is happening in RACF module ICHRIN00. Based on the addition of x'1900000F', it seems that RACF is adjusting for the "century bit" in a packed Julian date (most likely the "last used" date which presents in RACF message ICH70001I).  This is an IBM problem.

Resolution

The S0C7 abend occurred when it was trying to do a decimal add of "1900000F" to a field which contains "00E3E2CF".
This caused a S0C7 because x'00E3E2CF' is not a valid packed decimal value.
The abend is happening in RACF module ICHRIN00.
Based on the addition of x'1900000F', it seems that RACF is adjusting for the "century bit" in a packed Julian date (most likely the "last used" date which presents in RACF message ICH70001I).

The XCOM security code does any calculations with dates - nor do we pass any date-related parameters into our RACF security calls.

IBM has identified a recent PTF, UA95462.
