Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 1 Modification 0 and Release 2 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Customer reported 0C1 when cancelling * * QMGR. Logging was suspended at the time * * of cancel due to DASD problems allowing * * the log to fill. The cancel was to get * * things working again following DASD * * issues being resolved. * **************************************************************** The 0C1 occurred in CSQRUE01's FRR when attempting to return to RTM by branching to R14 (which was incorrectly restored to a value of 0 following a call to procedure CSQWRCRD). This was due to R11 incorrectly being used as the save area; R13 has been used since v8.
Problem conclusion
Code in csqrue01.plx was changed so that R13 is saved in the main line and restored in the FRR as opposed to R11. Also, a line of code that set R13 to point at a different address to provide a save area for CSQWRCRD was deleted as there's no reason the main register save area cannot be used.
