What Is a Cluster?
- A group of independent, but interconnected, computers that act as a single system
- Usually deployed to increase availability and performance or to balance a dynamically changing workload
What Is Clusterware?
- Clusterware is software that provides various interfaces and services for a cluster.
- Typically, this includes capabilities that:
– Allow the cluster to be managed as a whole
– Protect the integrity of the cluster
– Maintain a registry of resources across the cluster
– Deal with changes to the cluster
– Provide a common view of resources
UNDERSTANDING THE RAC ARCHITECTURE
Before considering the benefits of RAC (business or otherwise) it’s essential to have a clear understanding of the RAC architecture and terminology. The benefits of RAC come at a significant incremental cost in most cases, and in many respects the basis of the increased costs arises from the architecture of RAC itself and the changes to age old DBA processes and technologies.
The challenge for organizations is that differences in the Oracle architecture of a RAC deployment differ very significantly from a traditional single instance configuration. However, the typical slide show presentation of a RAC configuration doesn’t necessarily show the full complexity: and as is usually the case in the real-world compared to the marketing world, the devil is in the detail.
This section describes a simple single instance Oracle configuration, a simplified RAC architecture diagram and a real-world RAC deployment with all the incremental components you need for an enterprise-strength configuration.
What Are The Prerequisites To Learn Oracle RAC?
- General understanding of database administration
