Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of IBM MQ for z/OS Version 9       *
    *                 Release 0 Modification 0 and Release 1       *
    *                 Modification 0.                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: Expected channel initiator dumps are    *
    *                      not produced when an error is detected  *
    *                      in some circumstances.                  *
    ****************************************************************
    When the channel initiator detects an unexpected error condition
    it invokes CSQXDMPS to capture a dump for diagnostic purposes.
    An error in CSQXDMPS can cause this routine to fail silently
    depending on the contents of access registers, causing the dump
    to fail to be captured.
    

Problem conclusion

  • CSQXDMPS is changed to correctly capture the requested
    diagnostic dump.
