Hi,
Using virtual IP we can save our TCP/IP timeout problem because Oracle notification service (ONS) maintains communication between each nodes and listeners. Once ONS found any listener down or node down, it will notify another nodes and listeners. While new connection is trying to establish connection to failure node or listener, virtual IP of failure node automatically divert to surviving node and session will be establishing in another surviving node. This process doesn't wait for TCP/IP timeout event. Due to this new connection gets faster session establishment to another surviving nodes/listener.
Can someone explain about TCP/IP timeout problem here.
