SQL Database Auto close property || Do we set it to ON/OFF ?? || Ms SQL

When AUTO CLOSE option is turned ON (TRUE) for a database; SQL Server will close the user database after its use. The database is shut down cleanly and its resources are freed after the last user exits. The database will be turned ON next time when someone wants to access the database. For example, this re-open behavior occurs when a user issues a USE database_name statement. When AUTO CLOSE option is turned OFF (FALSE) for a database; The database remains open after the last user exits.
