Oracle Database Appliance Hardware Generation

Oracle Database Appliance

Oracle Database Appliance (ODA) is a pre-configured, highly available Oracle Database Engineered system. ODA system consists of hardware, software, storage and networking. The hardware configuration is designed to provide redundancy and protection against single points of failures in the system.

The Oracle Database Appliance saves time and money by simplifying deployment, maintenance, and support of high availability Database solutions.

ODA consists of two physical servers (Node 0 and Node 1), a storage shelf and optionally an additional storage shelf. The two independent physical servers are interconnected and direct attached to SAS and SSD storage.

ODA is basically a 2-node RAC cluster database system running Oracle Linux operating (OEL), Oracle Database, Oracle Grid Infrastructure (Clusterware and ASM). All these together provides the Oracle Database high availability running on ODA.

Advantages of Oracle Database Appliance

Oracle marketed ODA using the tagline "Simple, Reliable and Affordable".

• Simple: The ODA deployment made simple and easy to use by using the wizard based deployment.
• Reliable: The ODA platform provide complete high availability for Database and Application
• Affordable: With ODA you have the benefit of using Capacity-on-Demand Licensing. Pay for what you use.

Few other benefits includes

• Saves Time and Money
• Single Vendor Support
• High Performance and High Availability
• End to End Monitoring for all components
• Reduced Cost
• Easy management and Supporting
