VMS Help  —  RMU72  Dump  Database  Usage Notes
    o  To use the RMU Dump command with the Areas qualifier or the
       Lareas qualifier or the Snapshots qualifier for a database,
       you must have the RMU$DUMP privilege in the root file access
       control list (ACL) for the database or the OpenVMS SYSPRV or
       BYPASS privilege.

       To use the RMU Dump command with the Header qualifier for a
       database, you must have the RMU$DUMP, RMU$BACKUP, or RMU$OPEN
       privileges in the root file access control list (ACL) for the
       database, or the OpenVMS SYSPRV or BYPASS privilege.

       To use the RMU Dump command with the Users qualifier, you must
       have the RMU$DUMP, RMU$BACKUP, or RMU$OPEN privileges in the
       root file access control list (ACL) for the database or the
       OpenVMS WORLD privilege.

    o  The Spams_Only qualifier conflicts with the Lareas and
       Snapshots qualifiers; an error is generated if you specify
       the Spams_Only qualifier with either of the other qualifiers.

    o  The Header=All and Header=Buffers qualifiers provide two
       derived values to provide an estimated size of the global
       section. These appear in the dump file as:

          Derived Data...
             - Global section size
                 With global buffers disabled is 43451 bytes
                 With global buffers enabled is 941901 bytes

       The first value (With global buffers disabled) indicates the
       approximate size of the global section when local buffers are
       being used. The second value (With global buffers enabled)
       indicates the approximate size of the global section if you
       were to enable global buffers.

       You can use these values to determine approximately how
       much bigger the global section becomes if you enable global
       buffers. This allows you to determine, without having to
       take the database off line, how much larger to make the
       VIRTUALPAGECNT and GBLPAGES SYSGEN parameters to accommodate
       the larger global section.

       However, note that you must take the database off line if
       you decide to enable global buffers and you must shut down
       and reboot the system to change the SYSGEN parameters. It
       is recommended that you run AUTOGEN after you change SYSGEN
       parameters.

       Also note that these changes may require you to change the
       MONITOR account quotas as well to ensure the paging file quota
       is adequate.
