12 Preparing Nodes for Oracle Installation

NOTE: Ensure that the Gateway address is configured for the public network

interface. If the Gateway address is not configured, the Oracle Grid

installation may fail.

DEVICE=eth0

ONBOOT=yes

IPADDR=<Public IP Address>

NETMASK=<Subnet mask>

BOOTPROTO=static

HWADDR=<MAC Address>

SLAVE=no

GATEWAY=<Gateway Address>

Edit the

/etc/sysconfig/network

file, and, if necessary, replace

localhost.localdomain

with the qualified public node name. For example,

the command for node 1 will be:

hostname=node1.domain.com

Ty p e

service network restart

to restart the network service.

Ty p e

ifconfig

to verify that the IP addresses are set correctly.

To check your network configuration, ping each public IP address from a

client on the LAN that is not a part of the cluster.

Connect to each node to verify that the public network is functioning.

Ty p e

ssh <public IP>

to verify that the secure shell (ssh) command

is working.

Private Network

NOTE: Each of the two NIC ports for the private network must be on separate PCI

buses.

The grid infrastructure of Oracle 11gR2 (11.2.0.2) supports IP failover

natively using a newly introduced feature known as Redundant Interconnect.

Oracle uses its ora.cluster_interconnect.haip resource to communicate with

Oracle RAC, Oracle ASM, and other related services. The Highly Available

Internet Protocol (HAIP) has the ability to activate a maximum of four
