Oracle Error Message
ORA-12035: could not use materialized view log on “string”.”string”
Reason for the Error
The materialized view log did not exist or could not be used.
Solution
Use just REFRESH, which will reinstantiate the entire table. If a materialized view log exists and the form of the materialized view allows the use of a materialized view log, REFRESH FAST will be available starting the next time the materialized view is refreshed.
