3.1.5.9 Closing a Session

  • Article

A protocol session is closed by executing the following steps. The protocol does not send a packet to indicate session closure; instead, the underlying transport connection is simply closed.

  • If the initiator is closing the session and the OutgoingQueueReference.State is not OnHold:

    • The OutgoingQueueReference.State MUST be set to Disconnecting.

  • Close the underlying TCP or SPX transport connection.

  • Stop all timers.

  • The SessionState ADM element MUST be set to CLOSED.

  • If the initiator is closing a session and the OutgoingQueueReference.State is not OnHold:

    • The OutgoingQueueReference.State MUST be set to Disconnected.

    • If the OutgoingMessageTable ADM element is not empty, the protocol MUST start the Session Retry Connect Timer (section 3.1.2.3) and set the SessionState ADM element to WAITING_RECONNECT.
