**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Various abends occur when using shared * * dynamic queues, or creating and * * deleting shared queues frequently. * * Symptoms can include: * * 0C4 in CSQECLOS * * 5C6-00C510A5 in CSQECLOS * * 5C6-00C5101D in CSQECLOS * * 5C6-00D40017 in CSQECLOS * * 5C6-00E50009 in CSQECLOS * * 5C6-00C510AD in CSQEOCRQ * * 5C6-00C5111E in CSQELBK1 * * 5C6-00C511C8 in CSQEUCAT * * 5C6-00D40017 in CSQMINQ * * 0C4 in CSQMPOM * * * * In some cases the errors also lead * * to abnormal queue manager termination * * as reported by CSQV086E * **************************************************************** * RECOMMENDATION: * **************************************************************** A queue manager being notified that a shared queue SQ1 has been closed by another queue manager attempts to open the shared queue. During open processing, CSQEOSQ detects that there is already an sqtoken for the list header used by SQ1, and updates SQ1's control blocks with this sqtoken. CSQEOSQ then detects that the sqtoken is not for SQ1, and is associated with SQ0 - a shared queue that previously used the same list header. This queue had been deleted prior to the creation of SQ1, however CSQICDSQ had not yet been able to free its control blocks. While CSQEOSQ retried the open of SQ1 due to this error, SQ1 was deleted on another queue manager. CSQEOSQ detected that SQ1 no longer existed and returned CsqeRsnCodeSQueueRecNotFound however it incorrectly left the sqtoken set in the IVSP for SQ1. This led to CSQICDSQ attempting to free the sqtoken twice when cleaning up control blocks for deleted queues. Depending on how the SCB in the sqtoken was reused, this led to the reported abends.
Problem conclusion
CSQEOSQ has been corrected to only update the IVSP for the queue with the sqtoken after validating that the sqtoken is for the current queue using the list header, and not a queue that previously used the same list header. 100Y CSQEOSQ
