FAILOVER:
In the context of Oracle Net, failover refers to the mechanism of switching over to an alternate resource when connection to the primary resource gets terminated due to any reason.
Connection failure may be broadly categorized as:
Those that occur while making the initial connection.
Those that occur after a connection has been successfully established.
The first category of connection failure can be dealt with comparatively easily. If your attempt to connect to an instance fails, you can make the connection attempt again, but this time to a backup instance. As long as you have backup instances configured, you can continue trying to connect, until a successful connection is established. This process is technically termed as Connect Time Failover.
FAIL – SUCCEED – SUCCEED
