14 Configuring Your Network

NOTE: Windows Firewall is turned ON by default in Windows Server 2008 R2

SP1, which results in the Ping command to fail with Static IPs. Disable the

Windows Firewall to be able to Ping other nodes.

NOTE: Virtual internet protocol (VIP) is configured later and cannot be pinged

at this point.

Repeat step a through step b on the remaining nodes.

IP Address and Name Resolution Requirements

For a Cluster Using GNS

To set up an Oracle 11g R2 Remote Access Control using Oracle Global

Naming Server (GNS) you require:

• At least two interfaces configured on each node, one for the private IP

address and one for the public IP address.

• A Domain Naming Server (DNS) running in the network for the address

resolution of GNS virtual IP address.

• The DNS entry to establish DNS Lookup to direct DNS resolution of a sub-

domain to the cluster.

• A DHCP service running on the public network for the cluster.

• Sufficient addresses on the DHCP to provide one IP address for each node's

virtual IP, and three IP addresses for the cluster used by SCAN.

Table 2-2 describes the different interfaces, IP address settings, and the

resolutions in a cluster.
