Deployment Guide 23
NOTE: Oracle RAC 10g R2 is a complex database configuration that requires an
ordered list of procedures. To configure networking and storage in a minimal
amount of time, perform the following procedures in order.
Configuring the Public and Private Networks
NOTE: Each node requires a unique public and private internet protocol (IP)
address and an additional public IP address to serve as the virtual IP address for
the client connections and connection failover. The virtual IP address must belong
to the same subnet as the public IP address. All public IP addresses, including the
virtual IP address, should be registered with the domain naming system (DNS). If a
DNS server is not available, the IP addresses have to be registered in the hosts file
on all cluster nodes.
Depending on the number of NIC ports available, configure the public and
private interfaces as shown in Table 1-6.
Configuring and Teaming the Private Network
Before you deploy the cluster, assign a private IP address and host name to
each cluster node. This procedure ensures that the nodes can communicate
with each other through the private interface.
Table 1-7 provides an example of a network configuration for a two-node
cluster.
NOTE: This example assumes all the IP addresses are registered in the hosts file of
all cluster nodes.
NOTE: The two bonded NIC ports for a private network should be on separate PCI
buses. For example, a bonded pair can consist of one on-board NIC and one add-on
NIC card.
