A switchover means just switching roles between the primary database and standby db.
nswitchover, the primary database chnaged to a standby role, and the standby database changed to the primary role.
This is typically done for planned maintenance of the primary db server.
A failover is when the primary database fails and one of the standby databases is
transitioned to take over the primary role. Failover is performed only in the event
of a catastrophic failure of the primary database, and there is no possibility of
recovering the primary database in a timely manner. Failover may or may not result
in data loss depending on the protection mode in effect at the time of the failover.
