Oracle Error Message
ORA-16808: primary database is not open
Reason for the Error
A prior attempt to open the primary database was disallowed because the primary had shut itself down earlier after being isolated from both the fast-start failover observer and the target standby database for more than FastStartFailoverThreshold seconds. It was assumed that a fast-start failover was underway. Since that time, re-contact with either the observer or the target standby database indicates that no such failover had actually occurred. The primary database can now be opened.
Solution
Open the database by issuing the SQL*Plus ALTER DATABASE OPEN command.
