Oracle RAC High Availability and Policy-Based Database Management

Databases are the backbone of modern applications, and ensuring they remain online and performant is a critical task for any system administrator. This text-based course guides you through the foundational concepts of Oracle Real Application Clusters (RAC) and how to leverage policy-based management for high availability. You will transition from understanding basic database setups to designing, configuring, and maintaining robust, multi-node clustered environments. You will learn to manage resources dynamically, respond to node failures automatically, and keep critical applications running without interruption. What you'll learn: 1. Understand the core architecture and components of Oracle RAC, including Grid Infrastructure and shared storage. 2. Configure high-availability services to ensure seamless failover and load balancing for database clients. 3. Implement policy-based management to automatically allocate database resources based on real-time demand. 4. Monitor cluster health and troubleshoot common connectivity and node membership issues. 5. Practice setting up server pools and policies to optimize multi-tenant database environments. 6. Apply modern database observability principles to proactively detect performance bottlenecks. Starting with fundamental clustering terminology and installation pre-requisites, the course flows logically into resource management, service configuration, and practical failure scenarios. You will read structured explanations and analyze configuration scripts to build your database administration skills. This course is designed for beginner database administrators, system engineers, and IT professionals looking to specialize in high-availability systems. No prior clustering experience is required, though a basic understanding of database concepts is helpful.
