ORA-38742: Flashback log file has incorrect log reset status.

文档解释

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.

ORA-38742:Flashback log 文件的日志重置状态不正确。

4. 在运行Flashback Database之前,确保数据库参数,如_enable_flashback_restore_logs, _db_create_restore_logs, _flashback_restore_log_file和_flashback_restore_log_files参数,都设置正确。

5.完成上述步骤后,即可成功开始Flashback Database操作,以满足所需要进行的数据库回滚功能。
