Stopping a Session
Any running or waiting session can be stopped. You may want to stop a session when you realize that for example your interface contains errors or when the execution takes a long time.
Note that there are two ways to stop a session:
Normal: The session is stopped once the current task is finished.
Immediate: The current task is immediately interrupted and the session is stopped. This mode allows to stop long-running tasks, as for example long SQL statements before they complete.
