    * PROBLEM DESCRIPTION: CPSM workload may no longer be routed   *
    *                      to healthy CICS regions following a     *
    *                      -906 sqlcode from DB2..                 *
    ****************************************************************
    It is possible the CPSM workloads may no longer be routed to
    healthy CICS regions when using dynamic distribution program
    link or dynamic transaction routing.This occurs when a CICS
    region receives sqlcode -922 frbrc2 '00E70069' or sqlcode -906
    frbrc2 '00C30020' from DB2.
    The problem is that z/OS WLM is being informed, incorrectly,
    that the region is unhealthy.
    

Problem conclusion

  • DFHD2EX1 has been changed to ensure z/OS WLM still directs
    work to this region should a -906 or -922 have been received.
