"media recovery of direct load data that was not logged"
*Cause: A media recovery session encountered a table that was loaded
by the direct loader without logging any redo information. Some
or all of the blocks in this table are now marked as corrupt.
*Action: The table must be dropped or truncated so that the corrupted
blocks can be reused. If a more recent backup of the file is
available, try to recover this file to eliminate this error.
