By default, session timeout limits are set in the User Management, that is, an initial session duration and a maximum session duration. If the user does not request data for a certain period, the initial session duration expires. This initial session duration can be extend until a maximum session duration is reached.
The initial session duration and maximum session duration can be configured in the User Management administration. PPM uses these values to refresh the user sessions automatically, until the maximum session duration is reached.
This extension of the session duration takes effect after a certain time, that can be configured using the UMC_SESSION_REFRESH parameter in the server configuration file.
If the initial session duration or the maximum session duration for the system user has been changed, the PPM server must be restarted. Otherwise it may happen, that the user session expires before the maximum session duration has been reached.
