Purpose: Specifies the number of seconds that the listener waits once a connection request has been started. This wait usually involves the time needed to redirect the client抯 connection to a different port. If the redirect fails for some reason, the timeout causes the connect operation to terminate. The default value is 10 seconds. A value of 0 specifies an infinite timeout.
Sets the number of seconds that the listener waits for the server process to get a valid database query after the session has started.
