For detailed instructions for installing Oracle Real Application Clusters, see your Oracle documentation.
By default, the Oracle installer installs CRS on all nodes in a cluster. Instructions for installing CRS on a subset of Sun 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.
After installing the Oracle Real Application Clusters software, verify the installation of the software. For more information, see Verifying the Installation of Oracle Real Application Clusters.
