Failure Detection and Recovery

Client Side Heartbeat Timer

To aid in the detection of failed links or failed remote PC's the Georgia SoftWorks Client software supports a Client Timeout value. The client will send a heartbeat to the server at specified time intervals. At installation, this value is set to 300 seconds. This can be changed using the shortcut properties.

If the server does not receive data from the client in the specified time, the connection is terminated. The data can be keyboard, or mouse input as well as the heartbeat. When keyboard or mouse data is transmitted, or when a heartbeat detected the server's timer is restarted.

The heartbeat time is specified as an optional command line argument in seconds. 

Set the Georgia SoftWorks telnet client side heartbeat

Gs_clnt.exe /H1800

specifies a heartbeat time of 30 minutes (1800 seconds = 30 minutes). Normally there is no need to change this value. To disable the Client Side Heartbeat set  it to –1.

To change the Client Heartbeat

1.      Single click on the GS Telnet Client Shortcut.

2.      Right click, properties will be displayed, click on properties

3.      Select the Shortcut Tab.

4.      Change Target command line to reflect the new client side heartbeat timer.  The default command string is c:\gs _tnet\gs_clnt.exe /H300. The H300 parameter is the heartbeat count in seconds. 300 is 5 minutes. You may change or delete this parameter.

5.      Click on apply. The new heartbeat time interval takes effect when you log in.

Note: If an Inactivity Timeout occurs and the Session Saver is active the Session will be suspended; otherwise graceful termination will be initiated if specified.
