Client Session Timeout
Modifying client session timeout settings
The arcplan / Longview Analytics Server terminates clients who have been idle for an extended period of time. By default, this timeout is set to 6 hours and can be changed to meet your environment needs. This means that the server holds on to the the client session information, hence utilizing memory for a period of 6 hours after the last communication by the client session back to the server. In this case the memory in use increases (per client) and so the operating system (OS) may not be able to allocate more resources to the server processes. To modify this default client idle timeout a change is needed in the Administration Console.
In order to modify the DEFAULT Client timeout setting, follow these steps:
1. Launch the Administration Console, and connect to your arcplan / Longview Analytics server
2. Click on Load Balancing
3. In the RIGHT panel, right-click on the server listed and choose Server Settings...
4. Click on the Other Tab
5. Under MaxIdleTime, enter the desired value in minutes
6. Click OK to apply the change
Depending on your user needs we recommend that you set the "inactivity in minutes" entry between 30-90 minutes. In most cases you would want to allow additional buffer time before a client session is terminated so that clients are not being logged off too frequently.
The arcplan / Longview Analytics Server broadcasts a "KeepAlive" message every five minutes to all client sessions. This time span cannot be configured. When the server does not receive this message back from the client session for the second time in a row it begins the terminate process, to kill that client session on the server. The advantage of the "KeepAlive" function is that the server can detect and terminate such orphaned client sessions much earlier than the MaxIdleTime setting would.
The purpose of the MaxIdleTime is to terminate all client sessions after the specified idle time has been reached, regardless of whether the sessions exist on the client side or not.
