Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Applications using Content Based * * Filtering (CBF) hang or return MQRC * * 2551 (MQRC_SELECTION_NOT_AVAILABLE), * * and IIB Integration Servers / Execution * * Groups with CBF enabled do not shut * * down correctly when the fix for PI18601 * * is active on a queue manager with * * CONNSWAP=NO in the CSQ6SYSP section of * * the zparm. * **************************************************************** * RECOMMENDATION: * **************************************************************** PI18601 added code to the queue manager to make CBF enabled Integration server/Execution groups permanently non-swappable when they issue MQCONN to connect to the queue manager, and suspend until this was done. The mechanism used requires that any outstanding requests for temporary non-swappability are completed, however the task requesting that the address space is made permanently non-swappable will have issued a request for temporary non-swappability for the duration of the MQCONN call. This prevents the permanent request taking effect, and leaves the task suspended indefinitely. Any requests queued to this task will hang or timeout, and the task will not end when requested by IIB
Problem conclusion
CSQMCPRH is changed to remove its request for temporary non-swappability when requesting the address space is made permanently non-swappable, preventing the hang condition from occurring. 100Y CSQAPRHX CSQARIB CSQMCPRH CSQMCUWT
