A switch between the active and standby cards; the old active card may be dead prior to switchover (death of the active card is one of the causes for the switchover). Also known as failover.
A switch between the active and standby cards. The switchover can be initiated by command, or it can occur automatically when the active card fails.
The process of intentionally switching a database role from primary to standby, as well as from standby to primary, without resetting the online redo logs of the new primary database. This is a switchover operation, instead of a failover operation, because there is no loss of application data, and there is no need to reinstantiate the standby databases, including other standby databases not involved in the switchover operation. You cannot use a switchover operation to perform a rolling upgrade of Oracle software. However, it may be possible to use a switchover operation to perform a hardware-based rolling upgrade.

Switchover is the capability to manually switch over from one system to a redundant or standby computer server, system, or network upon the failure or abnormal termination of the previously active server, system, or network. Switchover happens with human intervention, unlike Failover.
