For Switchover we have a scenarion which involves preplanning. The primary and standby databases are available in the case of switchover. This is a reversible process.[/COLOR]
For Failover, there is no pre-planning[/COLOR]. Thisis a disaster condition.The primary database is no longer available.This process is irreversible and must be handled carefully.
Let us have a look at the Dbvisit database:
Dbvisit and failover
Failover:
dbv_oraStartStop activate ora
(where ora stands for the name of the database)
This command is run on the standby server. Now the standby database has been activated and is now the new primary database.
Switchover:
dbv_oraStartStop switchover ora
(where ora stands for the name of the database)
