VMS Help  —  RMU72  Open  Command Qualifiers, Global Buffers
    Global_Buffers[=(Total=i,User_Limit=j)]

    Allows you to set the basic global buffer parameters on each
    RMU Open command. If you specify the Global_Buffers qualifier,
    you can optionally specify values for the Total and User_Limit
    parameters:

    o  Total is the number of global buffers per node to allocate for
       this opened instance of the database (minimum = 5, and maximum

    o  User_Limit is the maximum number of global buffers to be
       allotted to any given user (minimum = 5, maximum = Total).

    The default values for Total and User_Limit are set by:

    o  The RMU Open command explicitly

    o  Values determined at the time the database was created

    If you do not specify a value for the Total or User_Limit
    options, the values are determined based on what they were when
    the database was created.

    If a database does not have global buffers enabled, the Global_
    Buffers qualifier is ignored. Use the RMU Dump command to see
    if global buffering is enabled or disabled. The RMU Dump command
    also shows the global buffer count and the maximum global buffer
    count per user. For example:

    $ RMU/DUMP MF_PERSONNEL
