This provides an easy way to manage the node down response for the incoming connections and provide the requests for that connection. Virtaul IP addresses keep track of the failures and if one node fails then the load gets shifted to another node that is present in the cluster. The VIP address is used by the applications and services of the Oracle RAC and then it also helps in connecting it to the Oracle RAC database. Oracle RAC is using the virtual IP address for each server that is present in the cluster as it allows easy management of the Oracle Clusterware by taking the subnet as LAN.
