Troubleshooting
Problem
You are unable to shutdown Xpediter/CICS in you CICS region and you receive an abend0C4 in DBUGDBXX.
Symptom
DFHAP0001 An abend (code 0C4/AKEA) has occurred at offset X'00002200' in module DBUGDBXX.
The symptoms of the problem are similar to the one described in APAR OA42454. However, the problem occurs with or without OMEGAMON active in the region.
Cause
You are missing a CA-ENF fix. Your current level of CA-ENF is making a similar mistake that the pre OA42454 version of OMEGAMON made. This causes the problem when CA-ENF intercepts control.
Diagnosing The Problem
From the dump, the 0C4 is at offset x'00002200' in program DBUGDBXX. The failing instruction is BF6F 2074 and register 2 (R2) has an address that is not valid: 0000000_40C55368. R2 is supposed to address DBUG's CPE at address 00000048_40C55368 (64bit).
Prior to the 0C4, DBUGDBXX loaded R2 with the CPE address 00000048_40C55368 and then issued an EXEC CICS RELEASE command to release program DBUG. On completion of the RELEASE command, DBUGDBXX was attempting to reference CPE field CPE_CURRENT_USERS (R2+74), but the top half of R2 was cleared, causing the 0C4.
It appears that R2 was updated during the RELEASE command processing.
Resolving The Problem
