Configuring Storage and Networking for Oracle 11g

RAC

This section provides information and procedures for setting up a Fibre Channel,

or iSCSI, or Direct-attached SAS cluster running a seed database:

• Configuring the public and private networks

• Configuring shared storage for Oracle Clusterware and the database using

OCFS2 or ASM

Oracle 11g RAC is a complex database configuration that requires an ordered list of

procedures. To configure networks and storage in a minimal amount of time, perform

the following procedures in order.

Configuring the Public and Private Networks

This section presents steps to configure the public and private cluster 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. All public IP addresses, including the virtual IP address, should be

registered with Domain Naming Service (DNS) and routable.

Depending on the number of NIC ports available, configure the interfaces as shown

in Table 5.

Table 5. NIC Port Assignments
