You can close an OLAP
session using the CLOSE SESSION statement.
CLOSE SESSION id | _ALL_ [USER=user-name ] [CUBE=cube-name]
[INACTIVE=seconds];
The ID is the unique
session identifier returned from the LIST SESSIONS statement. The
session is closed on the server. If the _ALL_ keyword is specified,
then all open sessions are closed. If the USER option is specified,
then only sessions owned by the specified user are closed. If the
CUBE option is specified, then only sessions that have the specified
cube open are closed. If the INACTIVE option is specified, then only
sessions inactive for the specified seconds are closed.
