Error description
ABN=0C4-00000004,C=R3600.701.IFC -CSQWTRC M=CSQGFRCV, LOC=CSQWVCOL.CSQWVCOL+000007E0 The 0C4 is occurring when CSQMCPEN attempts to trace the RAL. The problem appears to be due to pRAL being 0, indicating that there was no RAL when the module was called - although a RAL has subsequently been created, pRAL is not updated to refer to it. This causes CSQWVCOL to copy from low storage for a length determined from values in low storage, leading to the reported 0C4.

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C4-00000004 in CSQWVCOL issued * * in MSTR address space. * **************************************************************** * RECOMMENDATION: * **************************************************************** The problem happens when CSQMCPEN attempts to write the exit trace point. CSQMCPEN attempts to trace pRAL for a length of pRAL->RALTLEN, however pRAL itself is zero and the contents of pRAL->RALTLEN are whatever happens to exist at the RALTLEN offset from address 0. Normally this value will also be zero and therefore there is no issue, however if RALTLEN does contain a value (as is the case if PRIMEPSA is turned on) then CSQMCPEN will attempt to trace a length of storage, some of which may be inaccessible, resulting in the 0C4-00000004.
Problem conclusion
CSQMCPEN will now trace out the pRAL pointer itself, rather than the range of storage. 010Y CSQMCPEN
