Issue/Introduction

A Compuware job that interfaces with a DB2 region experiences a S0D3-13 abend with the last thing that occurred in the system trace being a return to the CCS module CASR230. After review of the dump by CCS support engineers the problem area pointed to IBM DB2 module DSNTAAL. CCS support requested that IBM take a look at the dump. IBM came back asking about CCS module CASR230R since this was seen in the SYSTRACE. Broadcom responded that CASR230R is a front end intercept for DSNTAAL. It is dynamically installed when the DB2 region is initialized and would be driven for any PC invocation of DSNTAAL. Upon further review of the dump by CCS support it appears the S0D3 abend occurs because the reusable-ASN bit, bit 63, in the located ASN-second-table entry (ASTE) is on. This is an IBM control block for handling cross-memory processing. Module CASR230R was reviewed further along with the mechanism that installs it. Neither of these alter this IBM control block. So once again we asked Compuware and IBM to review and respond. Compuware stated the reusable-ASN bit is set because its started task was started with REUSASID=YES.

 

Environment

Common Services IBM DB2, Compuware

Cause

After discussions between the Broadcom, IBM, and Compuware support teams it was determined that the problem was due to an IBM DB2 restriction as DB2 officially does not support the ASID Reuse facility

Resolution

Alter Compuware job to run without REUSEASID=YES
