Database is not in archiving mode. Extract may be forced to fetch LONG columns and may miss transaction data if the online logs are recycled.
Cause
The database is not in archiving mode. As a result, the redo log may not contain the full image of LONG columns and Extract may need to fetch the missing data to maintain data integrity. In addition, if capture lag is significant, Extract may miss transaction data if the online log recycles before required data can be captured.
Action
Stop Extract, enable archiving mode, then restart Extract.
