Oracle RAC databases involve both public and private networks, so for network partitioning and IP address planning, the following table lists the IP addresses, host names, and network connection types for the RAC databases to be installed:

Rac1
Host Name	IP Address	Sub-Network	Network type	Parsing method
Eth0	10.10.97.161	255.255.255.0	Public network
Eth1	192.168.2.116	255.255.255.0	Private network
	10.10.97.181	255.255.255.0	Virtual network
/etc/hosts

Public network and private network IP settings on the network card, virtual IP is not set.

Make the configured IP effective with ifdown,ifup:
