Oracle Database Appliance (ODA) and Its Components

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

Why ODA?

Traditional hardware deployments are complex, they can take from several weeks to months to implement. It depends on the several factors such as hardware procurement, deployment model choose by the organization and hardware & software certification.

The ODA deployment time is far less than a tranditional hardware deployment as ODA comes pre-configured with hardware and software in just on box. ODA includes Oracle Appliance Manager software to manage and maintain the
database server, patching/Upgrade ODA stack and troubleshooting.

H/W components of ODA

ODA consists of:

– 2 physical servers
– 1 Storage Shelf
– Optional additional storage shelf
– Networking
– Interconnect

S/W components of ODA

The Oracle Database Appliance runs Oracle Database Enterprise Edition, and customers have the choice of running Oracle Real Application Clusters (Oracle RAC) or Oracle RAC One Node.

• Oracle Enterprise Linux
• oracle Database Appliance Manager
• Oracle VM (Optional)
• Hardware Drivers
• Oracle Database 11g Enterprise Edition Release 2 and Oracle Database 12c Enterprise Edition
• Oracle Real Application Clusters One Node
• Oracle Real Application Clusters

Note: There are changes in ODA X6. Oracle introduced X6-2S, X6-2M and X6-2L which I will cover in a different article.

Oracle Database Appliance Deployment options:

You can deploy ODA in one of the following model:

1. Bare Metal Deployment
2. Virtualized Platform Deployment
