Session Management tab

 

The Petra Session Management tab lists and terminates active sessions on selected database servers.  A session is an active connection to the database server.  In addition to a background session for every user, each open module has its own session.  As an example, a user working with the Map Module, the Main Module, and the Cross-Section Module will have 4 total sessions.

Refreshes the active sessions for the connected servers.  Note that the Session Management tab will remain blank until this button is selected.

Kills the selected session.  When a Petra module crashes or closes unexpectedly, it can leave an open session with the database that prevents the user from reconnecting to the project.  Though a session will timeout on its own after a period of inactivity (120 seconds by default), the button terminates the selected open session so the user can reconnect immediately.
