Error description

  • PE02642-F504
    APAR PK04211 is in error.
    You issue an EUI OPERATE view for a resource and no data is
    returned as indicated by messages BBMXBD151I and BBMXBD23I.
    When you logon to the EUI from a different LPAR and issue the
    same OPERATE view, data is returned.
    Other symptoms include being able to view some resource
    information, while you do not receive other resource information
    for the same MAS. For example, you use EUI OPERATE view for
    PROGRAMS and data is successfully returned, however, when
    you inquire on CONNECTION for the same MAS, no data is
    available.
    The CMAS joblogs from connecting CMASs show a topology JOIN
    request for a MAS being processed in CMAS1, before the topology
    CONNECT has occurred in CMAS2.
    .
    If a CMAS recycles and connections to another CMAS which has
    just issued EYUXL0008I CICSplex registration complete and not
    yet connected its MASes, the recycling CMAS may not join the
    MASes from the other CMAS.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICSPlex/SM V3R1M0 Users                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: Topology Joins may not occur after      *
    *                      applying the PTF for APAR PK04211.      *
    *                      There will be no error messages or      *
    *                      diagnostic traces if this occurs.       *
    *                      The MAS will simply not be Joined       *
    *                      by one or more CMASes.                  *
    *                                                              *
    *                      This is more likely to occur when       *
    *                      one or more CMASes is restarted         *
    *                      while another CMAS is also in the       *
    *                      process of being restarted.  The        *
    *                      missing Joins will be for MASes         *
    *                      connected to the restarted 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.  Note however that any CMAS   *
    *                 that has not been restarted without the PTF  *
    *                 may experience the problem until it is       *
    *                 restarted with the PTF.                      *
    ****************************************************************
    When a CMAS is started, there is a interchange among all CMASes
    in the network of information about active MASes.  Multiple
    CMASes may broadcast information about the same MAS.  When this
    occurs, there is the possibility that one CMAS may send obsolete
    information about a MAS, that could result in an invalid Join
    request.  APAR PK04211 attempted to address this by adding a
    timestamp into the MAS information that method EYU0CPLT (CPLT)
    could interrogate to determine if it has the latest information.
    A logic error introduced by PK04211 causes CPLT to perform an
    invalid compare of the new timestamps.  This can result in a
    CMAS not Joining a MAS.
    

Problem conclusion

  • CPLT has been updated to correctly interrogate the timestamp
    added by APAR PK04211.
