Configuring private IP addresses for Oracle RAC

Private IP addresses are required by Oracle RAC to provide communication between the cluster nodes. Depending on your private network configuration, you may need one or more IP addresses. You can configure the private IP addresses for high availability using the PrivNIC or MultiPrivNIC agents.

Note:

IPv6 addresses are not supported in this release.

Description

PrivNIC configuration

Perform this configuration if you plan to:

  • Use a common IP address for Oracle Clusterware heartbeat and Oracle RAC database cache fusion and you plan to configure the IP address for high availability using the PrivNIC agent.

  • Or, use VCSIPC/LMX/LLT for Oracle RAC database cache fusion (you need an IP address only for Oracle Clusterware heartbeat in this scenario) and you plan to configure the IP address for high availability using the PrivNIC agent.

For instructions:

See Configuring the private IP address and PrivNIC for Oracle Clusterware.

MultiPrivNIC configuration

Perform this configuration if you plan to:

  • Use an IP address on each node for Oracle Clusterware heartbeat

  • And, use an IP address on each node for Oracle database cache fusion

  • And, configure the IP addresses for high availability using the MultiPrivNIC agent
