Error description

  • A NODATA condition is being returned on a NEWCOPY PHASEIN. The
    program for the newcopy is missing from the hardened resource
    map.  The resource map updates appear to be lost between the
    connect CMAS and the API CMAS.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICSPlex/SM V3R1M0 Users                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: In a multi-CMAS environment, API and    *
    *                      WUI requests for a specific resource in *
    *                      a MAS (e.g, PROGRAM=PROG1) may fail or  *
    *                      not return the proper results, if the   *
    *                      request is issued through a CMAS that   *
    *                      is not directly connected to the MAS,   *
    *                      and the resource was autoinstalled or   *
    *                      dynamically installed in the MAS when   *
    *                      the CMAS was not active.                *
    ****************************************************************
    * RECOMMENDATION: After applying the PTF that resolves this    *
    *                 APAR, all CMASes must be restarted.  Note    *
    *                 that the restarts do not need to occur at    *
    *                 the same time.                               *
    ****************************************************************
    CPSM uses Topology resource maps (resmaps) to determine what
    resources are installed in a MAS.  The resmaps are built by the
    CMAS that connects to the MAS at Topology Connect time (CONNECT
    CMAS), and are shipped to all other CMASes that manage the
    CICSplex the MAS is associated with when they Topology Join the
    MAS (JOIN CMASes).
    
    When resources are autoinstalled or dynamically installed in
    the MAS, the CONNECT CMAS updates its resmaps and passes the
    changes to the JOIN CMASes.  JOIN CMASes that are inactive at
    the time of the install should be passed the changes when they
    become active.  However, logic errors in the resmap update
    process may cause some changes not to be passed to these JOIN
    CMASes.  This will result in invalid resmaps in these JOIN
    CMASes, which can lead to errors if a request is made through
    these JOIN CMASes for a resource that did not get properly added
    to the CMAS's resmaps.
    
    Since resmaps are saved in a CMAS's data repository to minimize
    shipping at Topology Connect and Join time, it is possible that
    an invalid resmap can exist over multiple restarts of a MAS.
    

Problem conclusion

  • Methods EYU0TSSE (TSSE) and EYU0XCRB (XCRB) have been updated
    to resolve the logic errors that can result in invalid resmaps
    in JOIN CMASes when those CMASes are inactive when a resource is
    autoinstalled or dynamically installed in a MAS.
    
    To ensure that existing invalid maps are corrected, method
    EYU0XDIN (XDIN) has been updated to remove all resmaps from the
    data repository during CMAS initialization.  Since this removal
    process can elongate CMAS startup, it is only performed the
    first time a CMAS is started pointing to the libraries updated
    by the PTF that resolves this APAR.
