The client session

A desktop app session, also known as a client session, is created at Sign On (SO), when a session record is created in the database. The desktop app is not continuously connected to the server. The desktop app connects temporarily at SO and when it polls the server at the check update (CU) interval.

When the user shuts down the machine (or locks it and the “Stop checking for updates when Desktop is locked” option is selected in the Desktop App page in Settings in the

BlackBerry AtHoc

management system), the user’s session becomes stale because the desktop app stops polling the server and is not able to do a CU. The Desktop Sessions Maintenance job runs every 30 minutes to clean up stale sessions.
