+DFHAP0707 CICSDBDC An abend (code 0C1/AKEA) has occurred in task related user exit program DFHMQTRU. +DFHAP0001 CICSDBDC An abend (code 0C1/AKEA) has occurred at offset X'FFFFFFFF' in module DFHMQTRU. received shortly after CICS has recovered from a SOS situation. Abend occured after a BASR from DFHMQTRU +x42A70'. Reg 15 contains Msg handle create routine address (CSQBCRMH) loaded from CLOC +x'140'. CSQBCRMH was flushed after SOS but CLOC is never updated to reflect this. CSQBCRMH and CSQBPAPI were added by PK89844.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C1/AKEA occurs at offset * * X'FFFFFFFF' in module DFHMQTRU. * **************************************************************** * RECOMMENDATION: * **************************************************************** DFHMQCON loads programs CSQBCRMH and CSQBPAPI for exploitation of IBM WebSphere MQ V7 functionality. The ENTRY addresses are stored in the CLOC and are referenced by DFHMQTRU when it makes a call to one of these programs. However if CICS goes SOS, CSQBCRMH and CSQBPAPI may be flushed as they are loaded without the HOLD option specified. The CLOC is not updated in this case and as a consequence if DFHMQTRU issues a call to one of these programs an 0C1 abend occurs. KEYWORDS: abend0C1 abends0C1 WMQ messageAP0707 AP0707 messageAP0001 AP0001
Problem conclusion
The EXEC CICS LOAD commands in DFHMQCON, used to load CSQBCRMH and CSQBPAPI, have been modified to include the HOLD option. With this option specified the programs now remain in storage until explicitly released and will not be flushed in the event of CICS becoming SOS.
