Error description
While running along, the queue manager receives abend: CSQ1,ABN=0C4-00000038,U=MQUSER ,C=W9700.800.MMC -CSQMSCA ,M= CSQGFRCV,LOC=CSQTOPLM.CMQXRSCF+0001A254 . PSW=07741001 80000000 00000000 475DB52C General purpose register values 0-1 00000000_00000000 88FFFFFF_FFFFFFFF 2-3 00000000_00000000 00000000_475DD950 4-5 00000048_06000240 FFFFFFFF_FFFFFFFF 6-7 00000000_40A617A0 00000048_06000240 8-9 00000000_7F224408 00000000_00000001 10-11 00000000_00000001 00000000_00000001 12-13 88FFFFFF_FFFFFFFF 00000000_7F0663D8 14-15 00000000_00010000 00000048_06000440 . The change team has reviewed the dump. The ABEND0C4 occurs as rsxAccessCache is not setting pCache->pAnchor, causing subsequent processing to reference low storage (PRIMEPSA is active which means that an address value of FFFFFFFF_FFFFFFFF is taken).
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: When z/OS debug tool IGVDGNPP * * (PRIMEPSA) is running and a queue * * manager is creating queue * * SYSTEM.CHLAUTH.DATA.QUEUE and defining * * the default CHLAUTH records for the * * first time, it generates a 0C4 abend in * * CMQXRSCF. * **************************************************************** * RECOMMENDATION: * **************************************************************** A V800 queue manager running with OPMODE=(NEWFUNC,800) and queue manager attribute CHLAUTH(ENABLED), it can generate abend 0C4 in rsxSerialiseChlPrf (CMQXRSCF) when debug tool IGVDGNPP is running and the queue manager is creating and populating queue SYSTEM.CHLAUTH.DATA.QUEUE for the first time. Function rsxAccessCache fails to initialize a pointer in the CHLAUTH cache control block that causes the 0C4 abend when rsxSerialiseChlPrf is invoked.
Problem conclusion
Function rsxAccessCache sets the correct value in the CHLAUTH cache control block avoid the 0C4 abend. 000Y CMQXRSCF
