Requires read (R), write (W), and control access. Being the owner
    of the file is one way to get control access.

    Designates the recoverable facility that controls active recovery
    units for the file. Alternatively, when used with the /RU_
    FACILITY qualifier, the SET FILE/RU_ACTIVE command lets you clear
    the designated recoverable facility that controls active recovery
    units for the specified file.

    The SET FILE command is not supported for remote files. You
    must use the SET FILE command from the system where the file
    is located.

    For more information, see the RMS Journaling documentation.

    Format

      SET FILE/[NO]RU_ACTIVE=ru-facility data-filespec[,...]

1  –  Parameters

 ru-facility

    Specifies the number or name of a recoverable facility. It can
    be an integer from 0 through 255, or it can be the name of an
    VSI-registered recoverable facility.

    Facility numbers 1 through 127 are reserved by VSI; facility
    numbers 128 through 255 are available for user-written
    recoverable facilities. RMS is recoverable facility 1; specifying
    the number 1 is equivalent to using the text * corresponds to
    no recoverable facility and is equivalent to using the qualifier
    /NORU_ACTIVE. Currently, the only VSI-defined recoverable facility
    is 1 (RMS).

 data-filespec[,...]

    Specifies the file that is to be modified. If you specify more
    than one file, separate the file specifications with commas. The
    asterisk (*)  and the percent sign (%) wildcard characters are
    allowed. The file specification cannot include a node name, since
    the SET FILE command is not valid for network access.

2  –  Description

    The SET FILE/RU_ACTIVE command designates the recoverable
    facility that controls active recovery units for the file.
    Alternatively, when used with the /RU_FACILITY qualifier, the SET
    FILE/RU_ACTIVE command lets you clear the designated recoverable
    facility that controls active recovery units for the specified
    file. This is useful if a data file is unavailable due to active
    recovery units and an unavailable recovery unit journal.

                                 CAUTION

       When you clear the RU_ACTIVE attribute (using the command
       SET FILE/RU_ACTIVE=0/RU_FACILITY=1), the data in the file is
       likely to be in an inconsistent state. Do not use the data
       file unless you can ensure that the data is consistent.
       After clearing the RU_ACTIVE attribute, you can unmark
       the file for journaling, delete the file, and re-create a
       consistent file using a backup copy.

    You can determine the recoverable facility that controls active
    recovery units (if any) for the file by entering the DCL command
    DIRECTORY/FULL or DUMP/HEADER. You can use the ANALYZE/RMS_
    FILE/RU_JOURNAL command to determine the state of any active
    recovery units.

3  –  Qualifier

3.1    /LOG

       /LOG
       /NOLOG(default)

    Controls whether the SET FILE command displays the file
    specification and the type of facility that has been specified.
    By default, this information is not displayed.

4  –  EXAMPLES

    1.$ SET FILE/RU_FACILITY=1/RU_ACTIVE=0-

      _$ FINANCE_DISK:[PAYROLL]WEEKLY.DAT

      If the file WEEKLY.DAT is unavailable due to active recovery
      units and an unavailable recovery unit journal, you can use
      this command to gain access to the file. In this example, the
      recoverable facility is defined as RMS by the /RU_FACILITY=1
      qualifier. The RU_ACTIVE attribute that indicates active RMS
      recovery units for the file WEEKLY.DAT is cleared by the /RU_
      ACTIVE=0 qualifier.

                                 CAUTION

       The data in the file may be inconsistent if there are active
       recovery units. VSI recommends that you not use the contents
       of the data file unless you can verify that the data is
       consistent.

       VSI also recommends that you make a new copy of the file
       using the Convert Utility and that you use the converted
       copy in place of the original.
