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. |

This paper addresses the following topics:
• "Introduction" provides an overview of Oracle RAC and LDoms, and discusses the various deployment options for this solution. |
... • "Software requirements" lists the software and firmware requirements, and "Hardware configuration" describes the hardware used for an example configuration.
• "Software installation and configuration", "Network configuration", and "Storage configuration" describe the steps necessary to install and configure an example configuration.
• "Additional information" provides supplemental information, including performance considerations and known issues.

Alexandre Chartre joined Sun in April 1998 as a support engineer. He then worked on the Sun Cluster and Solaris kernel products in the Solaris sustaining organization for more than seven years. He is now a staff engineer with the Logical Domains engineering team, leading development around virtual I/O and integration with third party products. Alexandre's blog can be found at:http://blogs.sun.com/achartre.
Daniel Dibbets joined Oracle in August 2004. He is currently working in the RAC development organization, responsible for the certification of RAC in combination with virtualization solutions or in combination with new technologies such as 10 Gigabit Ethernet (10GbE), Reliable Datagram Sockets (RDS) and Fibre Channel over Ethernet (FCoE). In this role he has been a speaker at Oracle OpenWorld, written several Oracle white papers, and presented various Webcasts on these subjects.
Roman Ivanov joined Sun in January 2006. He is currently working in the Independent Software Vendors (ISV) Engineering organization helping software vendors to adopt Sun's technology and improve performance on Sun's hardware. Roman's blog can be found at: blog at http://blogs.sun.com/pomah.
