APAR status

  • Closed as program error.

Error description

  • You have a CPSM workload that is managed by both 4.2 CMASes and
    pre-4.2 CMASes. Using a WUI connected to a 4.2 CMAS, you use the
    'Set attributes' button to change the Algorithm type (field name
    ALGTYPE ).
    After doing so, you notice the TRANGRP status for this TRANGRP
    is now DORMANT in the pre-4.2 CMASes. Transactions in that
    TRANGRP no longer route properly in the routing regions
    connected to the pre-4.2 CMASes.

Local fix

  • Use a WUI connected to a pre-4.2 CMAS to reset the TRANGRP back
    to ACTIVE status.

    * PROBLEM DESCRIPTION:    You have a CPSM workload that is     *
    *                      managed by both CMASes executing V4.2   *
    *                      and V4.1 of CPSM.  Using a WUI server   *
    *                      connected to a V4.2 CMAS, you use the   *
    *                      'Set Attributes' button to change the   *

    *                      in CMASes executing V4.1 of CPSM.       *
    *                      Transactions in that TRANGRP no longer  *

    *                      nected to CMASes executing V4.1.        *
    ****************************************************************
    * RECOMMENDATION: After applying the PTF that resolves this    *
    *                 APAR, all CMASes which execute V4.1 of CPSM  *
    *                 must be recycled to pick up the new code.    *
    *                 Note that regions do not need to be brought  *
    *                 down and restarted at the same time.         *
    ****************************************************************
       Prior to V4.2 of CPSM, module EYU0WMUT (WMUT - Set Active
    TRANGRP Status) only updated the routing status of active WLM
    TRANGRPs.  In V4.2 this module was enhanced to allow the routing
    algorithm to be modified dynamically.  If a Method Argument List
    (MAL) to modify the routing algorithm for an active TRANGRP from
    a V4.2 CMAS is shipped to a CMAS running an earlier version of
    CPSM, the request will be interpreted as a request to update the
    status of the active TRANGRP.  A logic error in versions of
    EYU0WMUT prior to V4.2 will cause target active TRANGRPs to be
    set DORMANT.
    

Problem conclusion

  •    Module EYU0WMUT was modified to check the existence bit for
    TRANGRP_STATUS in the MAL to insure that the MAL was sent for
    the purpose of updating an active TRANGRP's status.
