VMS Help SET, FILE, /RU_FACILITY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The SET FILE/RU_FACILITY command allows you to identify the
    recoverable facility that controls active recovery units on the
    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.

    Format

      SET FILE/RU_FACILITY=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 a
    Compaq-registered recoverable facility.

    Facility numbers 1 through 127 are reserved by Compaq;
    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 RMS. The number
    0 corresponds to no recoverable facility. Currently, the only
    Compaq-defined recoverable facility is 1 (RMS).

    The recoverable facility that you specify is an input parameter
    that is used only to open the file; it does not actually modify
    any file attributes.

 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_FACILITY command allows you to identify the
    recoverable facility that controls active recovery units on the
    file. You can use any other SET FILE qualifier with the /RU_
    FACILITY qualifier.

    When a data file has active recovery units and RMS journaling
    cannot resolve the recovery units (for example, if the recovery
    unit journal is unavailable), the data file cannot be opened
    or deleted. The presence of active recovery units prevents you
    from unmarking (or marking) a file for any journaling type. With
    the SET FILE/RU_FACILITY/RU_ACTIVE command, you can clear the
    designated recoverable facility that controls active recovery
    units for the data file.

                                 CAUTION

       When you clear the RU_FACILITY attribute (with 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 - Examples

    1.$ SET FILE/RU_FACILITY=1/NORU_JOURNAL/NOAI_JOURNAL/LOG SAVINGS.DAT
      %SET-I-FILUNMARKAI, $DISK1:[PERSONAL]SAVINGS.DAT;1 unmarked for RMS
      after-image journaling
      %SET-I-FILUNMARKRU, $DISK1:[PERSONAL]SAVINGS.DAT;1 unmarked for RMS
      recovery-unit journaling
      %SET-I-MODIFIED, $DISK1:[PERSONAL]SAVINGS.DAT;1 modified
      $ DELETE SAVINGS.DAT;*

      This example shows the use of the /RU_FACILITY qualifier to
      allow SET FILE access to a data file. The SET FILE command
      identifies the recoverable facility holding the file and
      it also unmarks the file for recovery unit and after-image
      journaling. After these steps, it is then possible to delete
      the data file.

                                 CAUTION

       If it becomes necessary to use the /RU_FACILITY qualifier
       because of active recovery units, the data in the file may
       be inconsistent. Compaq recommends that you not use the data
       file unless you can verify that the data is consistent.

       Compaq 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.

    2.$ SET FILE/RU_FACILITY=RMS/RU_ACTIVE=0  SALES.DAT

      In this example, the recoverable facility for the file
      SALES.DAT is identified as RMS by the /RU_FACILITY=RMS
      qualifier, and the RU active file attribute (which indicates
      active RMS recovery units) is cleared by the /RU_ACTIVE=0
      qualifier. If the file SALES.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.

      As in the previous example, this operation leaves the data
      file in an inconsistent state. In general, use this command to
      delete the data file, then restore the file from a backup copy.
