  -- This procedure copies a backup piece that was originally written to an
  -- operating system file, onto sequential media. This requires allocating
  -- a sequential device first. Of course, this could copy to another operating
  -- system file if the NULL device is allocated.
  --
  -- A record is made in the controlfile as if the piece was just created and
  -- written to this output file. It can be queried from V$BACKUP_PIECE using
  -- the record ID returned. Note that no new entries are made in V$BACKUP_SET,
  -- V$BACKUP_DATAFILE, V$BACKUP_REDOLOG, or V$BACKUP_CORRUPTION.
  --
  -- It is acceptable to copy a backup piece when a backup controlfile has been
  -- mounted. However, note that the files named in the control
  -- file may no longer exist.
  --
  -- Input parameters:
  --   bpname
  --     Operating system file name of the existing backup piece. This will be
  --     read and copied to sequential media.
  --   fname
  --     Filename of the backup piece to be created. This will be translated
  --     into a file handle after the piece is created.
  --   tag
  --     The tag stored in the file header of the copied and backed up files,
  --     and also in the controlfile records describing those files.
  --   params
  --     This string is simply passed to the sequential file create OSD. It is
  --     completely port and device specific.
  -- Output parameters:
  --   handle
  --     The handle for the backup piece that was created. This is a permanent
  --     name that can be used to read this sequential file for restore. It
  --     can only be used with the same device type that was allocated at
  --     this call.
  --   comment
  --     The comment for the backup piece. This is any string that the OSD
  --     decided was useful. It will be a null string for operating system
  --     files. Note that this comment is not the same as the comment where the
  --     original backup piece was created.
  --   media
  --     The media handle returned by the operating system. This is the name
  --     of media where the file was created. It is not needed for retrieving
  --     the backup piece. For some devices this information will not be
  --     provided.
  --   concur
  --     TRUE if the device type used to create this piece
  --     supports multiple processes concurrently accessing the same media.
  --     If FALSE, it is best to only have one process at a time
  --     doing a restore of backup pieces with the same media handle.
  --   recid
  --     This is the ID of the record in the controlfile where the
  --     information about this backup piece was recorded. It can be used as
  --     the primary key to query V$BACKUP_PIECE.
  --   stamp
  --     This is a number that can be used to verify that the row in
  --     V$BACKUP_PIECE is really for this backup piece. The stamp combined
  --     with recid makes a key that is unique for this backup piece for all
  --     time.
  --   media_pool
  --     a number from 0-255 whose meaning is defined by rman or by 3rd-party
  --     media management software.
  -- Exceptions:
  --   NO-INPUT-FILENAME (ora-19605)
  --     src_name must be assigned a non-NULL string in copyControlFile.
  --   NO-OUTPUT-FILENAME (ora-19574)
  --     dest_name must be assigned a non-NULL string in copyControlFile.
  --   NAME-TOO-LONG (ora-19704)
  --     The specified file name is longer than the port-specific
  --     maximum file name length.
  --   TAG-TOO-LONG (ora-19705)
  --     The tag is longer than the port-specific maximum.
  --   DEVICE-PARM-TOO-LONG (ora-19702)
  --     The device parameter is longer than the port-specific maximum.
  --   CANT-GET-INSTANCE-STATE-ENQUEUE (ora-1155)
  --     The database is in the process of being opened, closed, mounted,
  --     or dismounted.
  --   DATABASE-NOT-MOUNTED (ora-1507)
  --     The database is not mounted.
  --   FILE-IN-USE (ora-19584)
  --     The specified output file is already in use by the database as a
  --     datafile or online redo log.
  --   DEVICE-NOT-ALLOCATED (ora-19569)
  --     This session does not have a device allocated.
  --   CANT-IDENTIFY-FILE (ora-19505)
  --     The file can not be opened.
  --   END-OF-VOLUME (ora-19630)
  --     end-of-volume was encountered while copying the backup piece.
  --   CORRUPT_BLOCK (ora-19599)
  --     A corrupt block was encountered.  Corrupt blocks are not tolerated
  --     in backup pieces.
  --   NOT-A-BACKUP-PIECE (ora-19608)
  --     The input file is not recognizable as a backup piece.
  --   CORRUPT-DIRECTORY (ora-19610)
  --     The backup piece directory is corrupt.
  --   IO-ERROR
  --     An error occured attempting to read the input file.
  --   CREATE-ERROR
  --     An error was reported by the OSD to create the sequential file.
  --   WRITE-ERROR
  --     An error was reported by the sequential write OSD.
