This document summarizes the high availability database design and implementation for Kmall.com using Oracle 11gR2. It includes: 1. A two node Real Application Clusters configuration with Oracle Solaris 10 and Oracle Sun Server X4-2L hardware. 2. A primary database structure with Data Guard configured to replicate to a physical standby database. 3. Testing of high availability features including role transitions, switchovers, and failovers using tools like the Data Guard broker.
