IV53253: SUPPRESS UNNECESSARY DAT_ACCEPT_COMPLETION_ERROR

A fix is available

 

APAR status

  • Closed as program error.

Error description

  • In some instances a DAT_ACCEPT_COMPLETION_ERROR may be
    delivered if the dat_cr_accept call is not finished completely
    by the time the response (say a disconnect or unreachable or
    something that will cause the connect request to be marked for
    deestruction) is received. This could lead to a case for
    example where both a DAT_ACCEPT_COMPLETION_ERROR and
    DAT_CONNECTION_EVENT_ESTABLISHED is delivered followed by a
    DISCONNECT event.

Problem summary

  • In some instances a DAT_ACCEPT_COMPLETION_ERROR may be
    delivered if the dat_cr_accept call is not finished completely
    by the time the response (say a disconnect or unreachable or
    something that will cause the connect request to be marked for
    deestruction) is received. This could lead to a case for
    example where both a DAT_ACCEPT_COMPLETION_ERROR and
    DAT_CONNECTION_EVENT_ESTABLISHED is delivered followed by a
    DISCONNECT event.
    

Problem conclusion

  • Generate a notification for the user if the connection
    requested is destroyed (in the accept processing path) only in
    the case where the EP hasn't already been disconnected. Else
    just go ahead and free the CR (connection request) without any
    notification.
