Pre-Installation Considerations

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

For other pre-installation considerations that apply to Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, see “Overview” in Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters.
