Oracle Error Message
ORA-16817: unsynchronized fast-start failover configuration
Reason for the Error
The fast-start failover target standby database was not synchronized with the primary database. As a result, a fast-start failover could not happen automatically in case of a primary database failure.
Solution
Ensure that the fast-start failover target standby database is running and that the primary database can ship redo data to it. When the standby database has received all of the redo data from the primary database, the primary and standby databases will then be synchronized. The Data Guard configuration may then fail over automatically to the standby database in the event of loss of the primary database.
