Specifies the number of minutes of inactivity after which the server automatically terminates network and mobile connections.
The minimum recommended setting is 15 minutes. If you specify a lower time, the server must reopen database server session too frequently, which slows server performance.
For mobile connections, XPC has its own internal time out. If the XPC time out value is shorter than the Server_Session_Timeout value, the XPC time out takes precedence.
