Connection and Communication Parameters
Connection parameters
To control the termination of connections when they are no longer intact.
Network server only.
All platforms except non-threaded UNIX applications.
Integer (in seconds)
120
If no LivenessTimeout value is set, the LivenessTimeout is controlled by the setting on the server, which defaults to 120 seconds.
A liveness packet is sent periodically across a client/server TCP/IP or SPX communications protocol to confirm that a connection is intact. If the client runs for the LivenessTimeout period without detecting a liveness request or response packet, the communication is severed.
Liveness packets are sent when a connection has not sent any packets for between one third and two thirds of the LivenessTimeout value.
When there are more than 200 connections to a server, the server automatically calculates a higher LivenessTimeout value based on the stated LivenessTimeout value. This enables the server to handle a large number of connections more efficiently.
The following sets a LivenessTimeout value of 10 minutes
LTO=600
Alternatively, you can set this parameter by entering its value in the LivenessTimeout text box of the Network tab of the ODBC Configuration dialog.
