Error description

  • A device attempts to connnect to the HOST.  The request is
    rejected by VTAM because the device already has a session.  The
    SNA sense that is issued by ISTTSCAF is not specific enough to
    identify the exact error.
      MSGIST380I IST380I REQUEST ACTPU SENSE 08120000 is issued to
    indicate the error.
      A CIDCTL ADD is attempted in ISTTSCAF.  The PU control block
    still exists from a prior session.  A network architectural
    error had occurred during the DACTPU flow.  This error caused
    the DACTPU response to be ignored by one of the VTAM
    components.  VTAM is still waiting on the response before
    purging the control block. The response will never come.
      This APAR is taken to change SNA sense to be more descriptive
    of the error.
      The cause of the error will have to be identified to totally
    resolve the hung device.  A VTAM trace can be taken to assist
    in that effort.  The trace must be active during the time the
    PIU flow occurred that contained the erroneous DACTPU response.
    An RNIO (TYPE=IO) trace is sufficient to document the failure.
    

Local fix

  • A VARY INACT,ID=LINEname being used by the device will make the
    line unavailable until VTAM can be restarted.
    When the specific architectural error has been identified via
    a trace, VTAM will provide a resolution for that problem.

    *                      a device trying to connect to VTAM.     *
    *                      The request is rejected because the     *

    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Sense code 08120000 'INSUFFICIENT RESOURCES', does
    not clearly specify the exact error.  In module ISTTSCAF,
    a CIDCTL ADD is attempted.  The CIDCTL fails and results
    in the above sense code being set.
    
    The problem is that the PU control block still exists from
    a prior session due to an error that occurred during DACTPU
    processing.  This error caused the DACTPU response to be
    ignored by a VTAM component.  VTAM will not purge the
    control block until a response is received, and in
    this scenario this will never happen.
    
    This apar will change the SNA sense to be more descriptive
    of the error.
    

Problem conclusion

  • Module ISTTSCAF has been changed to also check for a
    return code of NATDUPL 'DUPLICATE ADD'.  If this
    return code is received from the CIDCTL ADD, VTAM
    will send MSGIST380I with sense code 081E0004
    'SESSION FOUND BUT IN WRONG STATE'.
