Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICSPlex SM V4R1M0 Users                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: API, WUI and CICS Explorer requests     *
    *                      that originate from a CPSM V4R1M0 CMAS  *
    *                      for the LIBRARY, URIMAP, WEBSERV and    *
    *                      PIPELINE resource tables, will not      *
    *                      return records for these tables that    *
    *                      are installed in MASes that are         *
    *                      connected to CPSM V3R2M0 or V3R1M0      *
    *                      CMASes.                                 *
    ****************************************************************
    * 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.                               *
    ****************************************************************
    When a request is made for a CPSM resource table, the
    originating CMAS determines if Topology maps (CRESxxxx) are
    maintained for the table.  If maps are maintained for the table,
    the originating CMAS uses the maps to determine where to send
    the request.  If maps are not maintained for the table, the
    originating CMAS will send the request to all CMASes in the
    network that manage the CICSplex the request is associated with,
    where the local CMASes will determine which MASes to send the
    request to.
    
    While the tables mentioned above existed in V3R2M0 and in V3R1M0
    (all except LIBRARY), they did not have Topology maps maintained
    for them.  With V4R1M0, they now have Topology maps maintained
    for them, but only for MASes connected to V4R1M0 CMASes.
    
    When a request originates in a V4R1M0 CMAS, it will determine
    that Topology maps are maintained for these resources, but will
    only find maps for MASes connected to V4R1M0 CMASes, and as a
    result, will only request data from those CMASes.  This will
    cause existing records from MASes connected to pre-V4R1M0 CMASes
    to not be retrieved.
    

Problem conclusion

  • When a request is issued for one of these tables, Topology will
    determine if there are any pre-V4R1M0 CMASes active in the
    network that manage the CICSplex associated with the request.
    If there are pre-V4R1M0 CMASes in the network, then Topology
    will process as if the tables do not have maps, sending the
    request to all CMASes that manage the CICSplex.  If there are
    not pre-V4R1M0 CMASes in the network, then Topology will use the
    existing maps and only send the request where appropriate.
    
    In addition, since the WUI warning record count uses the
    Topology maps for its processing, no WUI warning record count
    will be issued for URIMAP, PIPELINE, WEBSERV, or LIBRARY when
    pre-V4R1M0 CMASes are in the network.
