Abstract
This chapter discusses features of the Oracle database that influence the architecture during the design stage of a highly available application based on Oracle Real Application Clusters (RAC). We will also point out where the availability can be limited, such as when a patch or a major upgrade must be performed. We will then have a look at intersite availability, discussing Data Guard for disaster recovery and Oracle Streams for message sharing and replication. A RAC solution is not an island; many components play a role, and many technologies can be leveraged to achieve a robust, highly available, and scalable application.
