Oracle RAC Online Mock Tests FAQs

1. What is Oracle Real Application Clusters (RAC)?

Oracle Real Application Clusters (RAC) is a feature of Oracle Database that enables a single database to be spread across multiple servers, providing high availability and scalability. RAC allows multiple servers to work together as a cluster, sharing the same database. It offers failover capabilities, load balancing, and improved performance for critical applications that require continuous availability and efficient resource utilization.

2. How does Oracle RAC achieve high availability?

Oracle RAC achieves high availability through:

Failover: Automatically switching to a standby node in case of server or instance failure.
Node Recovery: Reintroducing a failed node into the cluster after recovery.
Instance Monitoring: Continuously monitoring instances for availability and health.
Shared Storage: Using shared storage to prevent data loss in case of node failure.
Load Balancing: Distributing workload across nodes to prevent overloading.

These mechanisms ensure uninterrupted access to the database, minimizing downtime and data loss in the event of failures.

3. What are the benefits of using Oracle RAC?

Oracle RAC offers several benefits, including:

High Availability: Ensuring continuous access to critical applications and data.
Scalability: Adding nodes to the cluster to accommodate increased workload.
Performance: Distributing workload and utilizing resources efficiently.
Fault Tolerance: Withstanding hardware and software failures without service disruption.
Online Maintenance: Performing maintenance tasks without downtime.
Cost Savings: Maximizing resource utilization and reducing infrastructure costs.

These advantages make Oracle RAC an ideal solution for demanding enterprise environments that require both availability and scalability.

4. How does load balancing work in Oracle RAC?

Load balancing in Oracle RAC involves:

Distributing Queries: Routing queries to the least loaded instance for better performance.
Connection Pooling: Managing connections to ensure efficient resource utilization.
Automatic Service Registration: Automatically registering services with listener for load balancing.
Client-Side Load Balancing: Using client drivers to connect to the most appropriate instance.
Service Affinity: Directing requests to instances based on service definitions.

Load balancing optimizes resource usage and response times, contributing to a more efficient and responsive database environment.

5. How does Oracle RAC handle data consistency?

Oracle RAC ensures data consistency through:

Cache Fusion: Coordinating data access and synchronization across nodes.
Distributed Lock Management: Managing locks and concurrency control.
Global Resource Directory: Tracking data block ownership and location.
Global Enqueue Service: Managing enqueue and dequeue requests across nodes.
Redo Log Synchronization: Synchronizing redo logs to maintain data integrity.

These mechanisms maintain data consistency and isolation in a multi-node environment, preventing conflicts and ensuring transaction integrity.
