Oracle 9i Real Application Clusters Administration is written primarily for network or Database Administrator (DBA) responsible for the administration of Real Application Clusters.To use this document you should first read the Oracle 9i Database Administrator's Guide to become familiar with single-instance administrative procedures. You should then read Oracle 9i Real Application Clusters Concepts for a conceptual understanding of Real Application Clusters processing. You should also have installed Real Application Clusters using the document Oracle 9i Real Application Clusters Installation and Configuration and any platform-specific documentation.
