Adaptive Server uses the KEEPALIVE option of the TCP/IP protocol to detect clients that are no longer active. When a connection to a client is inactive for a period of time (the timeout period), the operating system sends KEEPALIVE packets at regular intervals. If it does not receive a response from the client machine for any of these packets, the operating system notifies Adaptive Server that the client is no longer responding. Adaptive Server then terminates the client’s connection.
The KEEPALIVE default timeout period is 2 hours (7,200,000 ms). To display the current time value, use the command for your platform as shown in the following sections.
