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.
