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.

The authors would like to thank Sridhar Kn, Ezhilan Narasimhan, Gia-Khanh Nguyen, Uday Shetty from Sun Microsystems, as well as Rahim Mau, Khader Mohiuddin from Oracle Corporation for their contributions during the certification of Oracle on Sun Logical Domains.

Oracle Database 10g и Real Application Cluster (RAC) отныне официально сертифицированы и поддерживаются на Sun Logical Domains (LDoms). Детали доступны так же в technology support matrix. Используя технологию виртуализации LDoms администратор максимально гибко управляет ресурсами системы и получает максимальный уровень безопасности, одновременно увеличивая уровень использования имеющихся серверов.

Среди множества возможных конфигураций я хотел бы специально отметить возможность создания кластера из нескольких нод, расположенных на одном единственном физическом сервере. Начните создавать свой кластер на чипе прямо сейчас.

Ожидайте, скоро тут появится пример конфигурации.

Oracle Database 10g and Real Application Cluster (RAC) now officially certified and supported on Sun's Logical Domains (LDoms). For details also check technology support matrix. With LDoms virtualization technology administrators can achieve great level of resource management and security level at the same time having higher utilization of servers.

Among several types of deployment I would like to mention one specifically for developers. By using LDoms now you can have single box with a number of guest domains configured as a cluster nodes. Start with making cluster on a chip.

Stay tuned for real world configuration example.
