Glossary
Oracle RACs: an overview
Oracle® defines its Real Application Clusters (RAC) option as “support for the transparent deployment of a single database across a cluster of servers, providing fault tolerance from hardware failures or planned outages. Oracle RAC running on clusters provides Oracle’s highest level of capability in terms of availability, scalability, and low-cost computing. Oracle RAC supports mainstream business applications of all kinds. Support includes online transaction processing (OLTP), decision support systems (DSS), and Oracle’s unique ability to support mixed OLTP/DSS environments. Support also includes packaged products such as SAP, PeopleSoft, Siebel, and Oracle E*Business Suite, as well as custom applications.”
Plug‑in for Oracle provides support for a limited number of Oracle versions and platforms in a RAC environment. The installation, configuration, backup, and restore procedures differ in a multi-instance RAC environment. This section of the guide offers specifics on how the plug-in operates in an Oracle RAC environment. It only points out the differences between the setup and usage of the plug-in in a multi-instance RAC environment vs. a single-instance or traditional non-RAC environment.
For a list of supported Oracle versions and platforms in a RAC environment, see the Dell NetVault Backup Compatibility Guide.
