The reconnect feature enables automatic reconnecting to a session that has undergone unintentional communication interruptions, thus preventing loss of session’s information.
Each session has one of the three-reconnect levels (modes):
None – Will not reconnect an interrupted session.
OnDemand – Will reconnect only sessions connected through the predefined connection.
Wireless – Will reconnect any session automatically.
The reconnect mode of a session is established at login time and never changes during the session’s life. It is requested by the client and is granted by the server.
The reconnect parameter value may be either "None", "OnDemand" or "Wireless".
