Error description
After attempting to process a SET SYSTEM EXCLMSG command, the following ABEND is issued in IBM MQ for z/OS Ver.9.0 Master: SEARCH ARGUMENT ABSTRACT PIDS/5655MQ900 RIDS/CSQJL002#L RIDS/CSQJC00B AB/S00C4 PRCS/00000004 REGS/0E1FA REGS/C0030 RIDS/CSQGFRCV#R SYMPTOM DESCRIPTION ------- ----------- PIDS/5655MQ900 PROGRAM ID: 5655MQ900 RIDS/CSQJL002#L LOAD MODULE NAME: CSQJL002 RIDS/CSQJC00B CSECT NAME: CSQJC00B AB/S00C4 SYSTEM ABEND CODE: 00C4 PRCS/00000004 ABEND REASON CODE: 00000004 REGS/0E1FA REGISTER/PSW DIFFERENCE FOR R0E: 1FA REGS/C0030 REGISTER/PSW DIFFERENCE FOR R0C:-0030 RIDS/CSQGFRCV#R RECOVERY ROUTINE CSECT NAME: CSQGFRCV The problem occurs when attempting to process a SET SYSTEM EXCLMSG command. As the messages being excluded can be either qmgr or chinit messages, the list of messages must be passed to the chinit if it is active. In this case the chinit is inactive, but an error in this checking causes an attempt to reference the non-existent chinit, leading to the 0C4.
Local fix
Remove any SET SYSTEM calls that might be executed before the chinit address space has started. For example, issue SET SYSTEM EXCLMSG(X511,X512) after QMGR chinit start up.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 0 Modification 0 and Release 1 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C4 experienced when using * * EXCLMSG command on queue manager whilst * * chinit is not up * **************************************************************** Copies of the value of EXCLMSG are kept in both SYSP (for qmgr) and XPAR (for chinit). During chinit start up, it is copied from SYSP to XPAR. This should not happen if the chinit is not up. If chinit isn't running, MGBL.pMoverAlet is set to 0. Call to CSQMCMAS, to check if chinit is up, is not done as it depends on MGBL.pMoverAlet not being zero. csqmcmasrc is not set to an error return code as a result and copying is attempted - hence the abend.
Problem conclusion
Code in csqjc00b.plx corrected so that CSQMCMAS is also called when the chinit is not active
