Oracle : Ошибка ORA-38732

"Expected file size %s does not match %s."
*Cause: The file size indicated in the control file did not match
the file size contained in the flashback log file header.
The flashback database log file was corrupt.
*Action: If you are doing a FLASHBACK DATABASE, then the flashback
cannot be performed because of the corrupted log. A restore
and an incomplete recovery must be performed instead.
