Chapter 2. Oracle 11g RAC Architecture

Oracle 11g RAC architecture differs in many respects from single-instance non-RAC Oracle database environments. In this chapter, we will provide you with a blueprint on how to apply best practices for leveraging your investment in Oracle RAC to create a highly available architecture. We will also discuss the various components of an RAC cluster.

Due to the complex nature of an Oracle 11g RAC environment, we will cover the various components that are unique to Oracle 11g RAC environments and constitute the Oracle system architecture. As such, we will provide key coverage of architectural design and implementation guidelines for successfully deploying Oracle 11g Real Application Clusters. We will also provide coverage of the most important new features that will benefit the Oracle RAC database administrator.
