ORA-00354

Error: ORA-00354: corrupt redo log block header

Causa: The block header on the redo block indicated by the accompanying error is not valid. The block number and time-stamp are given in an accompanying message.

Acción: Perform recovery with a good version of the redo log or perform cancel-based recovery up to, but not including, the corrupted redo log file. If this happens when archiving, archiving of the problem log can be skipped by clearing the log with the UNARCHIVED option. This must be followed by a backup of every datafile to insure recoverability of the database.
