Requirements for Using the Cluster File System

You can store all of the files that are associated with Oracle Parallel Server/Real Application Clusters on the cluster file system, namely:

• Application binary files

• Control files

• Data files

• Log files

• Configuration files

The input/output (I/O) performance during the writing of redo logs is affected by the location of the device group for redo logs. For optimum performance, ensure that the primary of the device group for redo logs is located on the same node as the Oracle Parallel Server/Real Application Clusters database instance. This device group contains the cluster file system that holds online redo logs and archived redo logs of the database instance.

See the planning chapter of the Sun Cluster 3.1 10/03 Software Installation Guide for information about how to create cluster file systems.
