Running Oracle Real Application Clusters (RAC) on Sun Logical Domains (LDoms)
By Roman Ivanov on Jun 04, 2009
BluePrint of Running Oracle Real Application Clusters (RAC) on Sun Logical Domains is available now. In this blueprint you will find step-by-step configuration example of two nodes in two guest domains located on two separate boxes. Use it as starting point to build your own cluster.
This article discusses running Oracle Real Application Clusters (RAC) on servers configured with Sun™ Logical Domains (LDoms). Sun LDoms virtualization technology allows the creation of multiple virtual systems on a single physical system, and enables fine-grained assignment of CPU and memory resources to an Oracle RAC workload. When deployed on Sun's CoolThreads™ technology-based servers, with up to 256 threads per system, this solution provides a powerful platform for both development and production environments. In development environments, multiple Oracle RAC nodes can be deployed on the same physical server to reduce hardware costs, while a production environment can place each Oracle node on a separate physical server for increased availability.
