• Overriding Networking Defaults for Oracle 10g, 11g, or 12c Oracle Clusterware

• Installing Oracle Clusterware on a Subset of Oracle Solaris Cluster Nodes

• Next Steps

For detailed instructions for installing Oracle RAC, see your Oracle documentation.

Installing Binary Files and Configuration Files on a Shared File System

To simplify the maintenance of your Oracle installation, you can install the Oracle binary files and Oracle configuration files on a shared file system. The following shared file systems are supported:

• The Sun QFS shared file system

• The PxFS-based cluster file system

• The Oracle ACFS file system

• A file system on a qualified NAS device

If you are installing the Oracle binary files and Oracle configuration files on a shared file system, specify the absolute paths to the file system when the Oracle installation tool requests this information. Do not use a symbolic link whose target is the shared file system.

To install Oracle binary files and configuration files on a local file system, follow the usual procedures as described in your Oracle Database documentation.

Overriding Networking Defaults for Oracle 10g, 11g, or 12c Oracle Clusterware

By default, the network interfaces panel of the Oracle 10g, 11g, or 12c Universal Installer shows all interfaces as private. If you are installing Oracle 10g, 11g, or 12c RAC for use with Oracle Solaris Cluster software, override these defaults as follows:

• Ensure that clprivnet0 is the only private interface.

• Set the public network interfaces to public.

• Ensure that all other interfaces are not used. These interfaces represent the underlying network interfaces for the cluster interconnects.

Installing Oracle Clusterware on a Subset of Oracle Solaris Cluster Nodes

By default, the Oracle installer installs Oracle Clusterware on all nodes in a cluster. Instructions for installing Oracle Clusterware on a subset of Oracle Solaris Cluster nodes are available at the Oracle MetaLink web site. See Oracle MetaLink note 280589.1 How to install Oracle 10g CRS on a cluster where one or more nodes are not to be configured to run CRS.

Next Steps

The next steps depend on the location of your Oracle binary files and Oracle configuration files. See the following table.
