ORA-38738: Flashback log file is not current copy.
Cause: A check of flashback database log file header at database open found that the flashback database log appeared to be an incorrectly restored backup. Flashback database log files cannot be backed up and restored.
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.
Error Type: ORA
