Oracle : Ошибка ORA-38742

"Flashback log file has incorrect log reset status."
*Cause: The flashback database log file header had log reset
data that was different than the control file. The log
was probably an incorrectly restored backup. Flashback
database logs cannot be backed up.
*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.
