Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 2 Modification 0 and * * Release 3 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: An S0C4-11 abend is seen during an * * MQDISC call in an application address * * space that is connected into the Queue * * Manager. * **************************************************************** An S0C4-11 abend is seen during an MQDISC call in an application address space that is connected into the Queue Manager as part of implicit commit processing. The module CSQIRTAG is incorrectly called as part of this processing and when called in this way can cause the S0C4 abend due to not having the expected valid RURE pointer value.
Problem conclusion
The code has been corrected so that CSQIRTAG is no longer incorrectly called as part of implicit commit processing from an MQDISC api call made by an address space that is connected into the Queue Manager.
