Oracle Database 10g with Oracle Real Application Clusters (RAC) using Reliable Datagram Sockets (RDS) on Solaris 10 is the subject of a Sun BluePrints article that describes the software and hardware configurations, along with the steps necessary to install and configure the components. Authors Uday Shetty and Peter Sciarra also explain the testing used to validate the example configurations defined in the article.

Two example configurations are detailed in the 33-page PDF. One is based on UltraSPARC technology, and one based on x64 processors. The configurations specifically involve the Sun SPARC Enterprise T5240 and T5440 servers, based on the UltraSPARC T2 Plus processor; the Sun Fire X4140 and X4240 servers (x64-based configuration); and the Sun StorageTek 6140 Array.

The article begins by providing an overview of Oracle RAC and RDS, InfiniBand fabric and the Brocade storage area network. The authors point out that Oracle RAC is a key component of the Oracle enterprise grid architecture, and the cluster interconnect is a key to maximizing grid performance. Oracle RDS provides a lightweight, reliable network protocol with low overhead, scalable to hundreds of nodes. Combined with InfiniBand, the RDS protocol provides a high performance cluster interconnect for Oracle RAC 10g Release 2, yielding both a factor of ten bandwidth advantage and a factor of ten latency reduction compared to Gigabit Ethernet, the writers note. RDS using InfiniBand makes efficient use of the server processors by offloading end-to-end error checking to the InfiniBand fabric itself. This approach frees processor cycles for application processing, allowing significantly greater processor scaling compared to Gigabit Ethernet implementations.

Discussions on the various Sun hardware and storage platforms used in the example configurations are included.

The complete configuration process used by Shetty and Sciarra is recounted, including Solaris configuration, driver configuration and tuning parameters (scsi driver, RDS driver, etc), and Oracle RAC configuration, ASM and database creation and configuration, networking setup and storage configuration. Configuration guidelines and software requirements are also provided.
