Integer (minutes)
10
Purpose
The KeepAliveTime parameter specifies the number of minutes that each running application checks whether the connection to the presentation client is still valid, by sending a ‘keep alive’ message to the client after every period specified by this parameter expires without any activity.
This check is necessary because the presentation client can detach without any notification from the TCP/IP connection (for example, the modem is unplugged) and therefore can tie up an in-use licence. If the connection is still valid, this process acts as a do nothing event (but obviously at the cost of a message turnaround). If the connection is no longer valid, the client is terminated and signed off.
By default, the application server performs this check after every ten minutes of inactivity. The minimum value that you can specify is 1 minute.
When an application server recognizes that a connection has been lost, it does not know whether the presentation client has also realized that state. As a result, it waits for the number of seconds specified by the ReconnectWaitTime parameter, to give the presentation client the chance to reconnect. (A ReconnectWaitTime parameter value of zero (0) indicates that the KeepAliveTime parameter value is used.)
Parameter is read when …
The application server node is next initialized; for example, when you restart the application server.
