one of the available disk drives used by the database. While waitinig
for a replacement drive, the
OBA removed the un-needed data from the database and during the
removl the
SALES_HISTORY table was dropped accidentally.
Within few minutes a second hardware failure corrupted another disk
drive, resulting in
the loss of the current online redo log files and the logical back

files were not multiplexed and the current redo log file is not yet
archived.
