Oracle : Ошибка ORA-38739

"Flashback log file is more recent than control file."
*Cause: The control file change sequence number in the flashback
database log file was greater than the number in the
control file. This implies that the wrong control file
was being used. Note that repeatedly causing this error
can make it stop happening without correcting the real
problem. Every attempt to open the database will advance the
control file change sequence number until it is great enough.
*Action: FLASHBACK DATABASE can only be used with the current
control file. If it is not available, then a restore
and an incomplete recovery must be performed instead.
