Operating System Session Shutdown

Always stop the database server explicitly before closing the operating system session.

If you close an operating system session where a database server is running, or if you use an operating system command (other than stop_iq) to stop the database server, the server shuts down, but not cleanly. Next time the database is loaded, recovery happens automatically.

Note: An example of a command that does not stop a server cleanly is stopping the process in the Windows Task Manager Processes window.
