Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: A 0C4 abend may occur in CSQVCRTH * * during memory termination processing * * for an application address space * * connected to the same queue manager as * * another application address space that * * is going through the memory termination * * processing, if the processing takes a * * long time or hangs while holding a * * resource ENQ. * **************************************************************** * RECOMMENDATION: * **************************************************************** When application address spaces go through memory termination, the processing gains the SYSZCSQ3 CSQYALLI ENQ. If while this ENQ is held, the processing hangs memory termination processing for other address spaces will wait for this ENQ. If wait is over 4 minutes in length, the processing will itself be cancelled automatically. This results in the recovery routine for memory termination processing being entered, which will attempt to gain the ENQ again. As this has been previously requested for the same TCB, the ENQ call returns RC 14. This is incorrectly handled in this case, and processing continues as if the ENQ is held, when it is not. This can result in 0C4 abends in CSQVCRTH during the later recovery processing.
Problem conclusion
The recovery routine for memory termination processing in this case has been updated to correctly handle the return code 14 from the request for the ENQ, and to subsequently wait for the ENQ to be available. 100Y CSQ3SSES
