Oracle Error Message
ORA-16216: Log stream sequence error
Reason for the Error
The log stream being processed did not follow the last processed stream.
Solution
If the database is in an active configuration, issue an ALTER DATABASE START LOGICAL STANDBY APPLY NEW PRIMARY command to synchronize log stream data with the current primary database. If the database is not in an active configuration, manually add the next dictionary-begin log file that followed the previous log stream.
