Error description

  • After applying the PTFs for PM67891 (UK83850 or UK83851) message
    DFHUS0002 with code(x'030C') can occur when a userid used for
    session preset security completes DELETE_USER processing in
    DFHUSAD.
    .
    The problem occurs because the format of the USD1 directory
    key used for these session signons was changed by PM67891, but
    the change was not correctly reflected in the USUDB.  When the
    DELETE_USER processing is done in DFHUSAD the USD1 directory
    key is reconstructed using information in the USUDB.  DFHUSAD
    fails to find this incorrect entry in the USD1 directory so
    assumes there is a major problem with the state of the
    directories and terminates CICS.
    .
    MRO connections using preset security are probably unlikely to
    see the problem as they will typically remain inservice for
    the lifetime of the CICS region.  The problem is more likely to
    be seen using EXCI connections, especially if USRDELAY is set
    to a low value and the EXCI session userid then times out.

    ****************************************************************
    PM67891 altered the way that session userids were signed on.
    The format of the USD1 key was altered so that these signons
    were not subject to RACF notifications.
    
    When a session userid gets deleted DFHUSAD recreates the USD1
    directory key before removing the user from the directory.
    The key generated during DELETE_USER processing does not match
    the one created during ADD_USER processing.  This causes DFHUSAD
    to fail to locate the correct entry in the USD1 directory.  The
    failure to remove the entry from the USD1 directory causes
    DFHUSAD to believe that its directories are in an inconsistent
    state.  Message DFHUS0002 with code x'030C' is issued and CICS
    is terminated.

Problem conclusion

  • UK83850 UK83851
    DFHUSAD has been changed to correctly delete session userids
    from the USD1 directory.
