EPM Workspace uses two mechanisms to manage the users active session. First, EPM Workspace sends keep alive requests to all application servers (including its own) which have been used in the users current session. The keep alive maintains the session between the browser and the application server so that the application server does not invalidate the session. For example, once a Financial Reporting report has been opened, EPM Workspace sends keep alive requests to the Financial Reporting server so that the user can open more Oracle Hyperion Financial Reporting, Fusion Edition reports without having to reopen the session with the Financial Reporting application server. The interval for sending these requests is configured by Workspace Server Settings, KeepAliveInterval property. This property must be set to less then the timeout value for any application server used by EPM Workspace, if it is set to a higher value, the user may receive error messages due to application server timeouts. The second mechanism is designed to close the users session when the user has stopped using EPM Workspace but has not closed the browser. If there is no activity in EPM Workspace per the Workspace Server Setting, SessionTimeout property, the user is warned that the session is about to end. If the user does not take action within five minutes, the user is logged out.
To modify the values, make changes in General Workspace Properties.
The units are in minutes. The defaults, shown above, are 10 minutes for KeepAliveInterval and 30 minutes for SessionTimeout.
