Pre-installation considerations for using Oracle Parallel Server/Real Application Clusters with the cluster file system are missing from “Overview” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.
Oracle Parallel Server/Real Application Clusters is a scalable application that can run on more than one node concurrently. You can store all of the files that are associated with this application on the cluster file system, namely:
Binary files
Control files
Data files
Log files
Configuration files
For optimum I/O performance during the writing of redo logs, ensure that the following items are located on the same node:
The Oracle Parallel Server/Real Application Clusters database instance
The primary of the device group that contains the cluster file system that holds the following logs of the database instance:
Online redo logs
Archived redo logs
