o  The Enable and Disable qualifiers are mutually exclusive.

    o  The RMU Set Buffer_Object command requires exclusive database
       access; that is, the database cannot be open or be accessed by
       other users.

    o  Buffer objects are memory resident and thus reduce the amount
       of physical memory available to OpenVMS for other uses. Buffer
       object use requires that the user be granted the VMS$BUFFER_
       OBJECT_USER rights identifier. The system parameter MAXBOBMEM
       needs to be large enough to allow all buffer objects for all
       users to be created. For further information regarding Fast
       I/O, consult the OpenVMS documentation.
