ORA-16808

Primary database is not open.

Cause

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 the number of seconds specified by the FastStartFailoverThreshold configuration property. It was assumed that a fast-start failover was underway. Since that time, the primary database reestablished contact with either the observer or the target standby database indicating that a fast-start failover had not actually occurred.


Action

Open the database by issuing the SQL*Plus ALTER DATABASE OPEN command.
