Reconnecting to Servers after a Disconnection
You can be disconnected from ICA sessions because of unreliable networks, highly variable network latency, or range limitations of wireless devices. With the automatic client reconnection feature, the client can detect unintended disconnections and automatically reconnect users to the affected sessions.
When this feature is enabled on a machine running Presentation Server, you do not have to reconnect manually. Instead, a message box appears indicating that automatic reconnection is under way, and the client tries to reconnect until it is successful or the user cancels the reconnection attempts. If you require users to be authenticated again, a dialog box requesting credentials appears during automatic reconnection. Automatic reconnection does not occur if you exit applications without logging off.
Please refer to the Presentation Server documentation for information on how to implement automatic client reconnection.
Session Reliability
With the session reliability feature, users continue to see a published application’s window if the connection to the application experiences an interruption, and no message box explaining that the client is trying to reconnect appears for three minutes (at which stage the user can cancel the reconnection attempt). For example, wireless users entering a tunnel may lose their connection when they enter the tunnel and regain it when they come out on the other side. During such interruptions, the session reliability feature enables the session window to remain displayed while the connection is being restored.
To reduce the likelihood that users continue to click links or type text while the connection is being restored, mouse pointers become hourglass icons while the application is unresponsive.
To turn session reliability on for a specific connection
1.In the ICA Client Editor, open the connection file.
2.From the Connection Properties tab, under Session Reliability, choose Enable and enter the port number to which you want to connect. If the session reliability feature is enabled, the default port used for session communication with the server changes from 1494 to 2598. Please refer to the Presentation Server documentation for information on how to change the port used for session reliability.
3.Click Save.
