VMS Help  —  SET  FILE  Qualifiers  /SHARE
    Allows you to enable or disable global buffers or statistics on a
    file currently being accessed by other users.

    Requires SYSPRV privilege.

    Only new accessors of the file acquire the new settings. For
    example, if a file is opened with no global buffers specified and
    the SET FILE/GLOBAL=n/SHARE command is issued, only new accessors
    of the file will use global buffers. If /STATISTICS is enabled on
    an active file, only operations performed by new accessors of the
    file are measured.

    If a file is already open with global buffers, any new number of
    global buffers will not take effect until the file is closed by
    all accessors of the file.

    The /SHARE qualifier is valid only with the following qualifiers:

    o  /[NO]GLOBAL_BUFFER=n

    o  /[NO]STATISTICS
