Usage Notes
When the LOGOFF command is executed, a logoff request is sent to the database for each session to be logged off. When the SES ALL operand is used, database logons are disabled when all sessions have been logged off.
Outstanding requests for sessions to be logged off are aborted, and any results are returned to the requesting application. Subsequent requests for a logged-off session are returned to an application with an error message.
To log off a session, issue the LOGOFF command from the TDP that the session is running on.
Performance Monitor ABORT SESSION Command
There is a separate performance monitor command, ABORT SESSION, that is executed from the RDBMS console. The ABORT SESSION command can log off any database session on any mainframe or LAN client. It can also log off sessions based on username only (the host id and session number are not required).
