ORA-16817: unsynchronized fast-start failover configuration

ORA-16817: unsynchronized fast-start failover configuration
Cause: 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.
Action: 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.

ORA-16817：不同步的快速启动故障转移配置,
.原因：快速启动故障转移目标备用数据库未与主数据库同步。因此，在主数据库故障的情况下，无法自动执行快速启动故障切换。,
.操作：确保快速启动故障转移目标备用数据库正在运行，并且主数据库可以向其发送重做数据。当备用数据库从主数据库接收到所有重做数据时，主数据库和备用数据库将被同步。在主数据库丢失的情况下，Data Guard配置可能会自动故障转移到备用数据库。,
