Expanding on Oracle10g RAC Knowledge

Enhancing RAC Knowledge to Cultivate Relevant Expertise

Transferring previous expertise in cluster-related technology is probably a typical and countable task. Thus, the experience attained with the Oracle8i Parallel Server (OPS) most likely applied to those who first used Oracle9i RAC. Historically, however, the principle of database clusters had existed since Oracle Version 6, the first version I actually used in production in 1991. But it is certain that great improvements first occurred with Oracle9i RAC, and that evidently Oracle10g releases have become an enormous success for all enthusiasts of this technology. You can join for free the Oracle RAC SIG group, partly sponsored by IOUG, and periodically attend free seminars, which enhance your RAC knowledgebase. The website can be reached at, and it keeps growing with good work.

I have personally worked with Sun clusters to implement grid, and HARD (Hardware Available Resilient Data),i.e., hardware-driven high availability architectures, such as those implementing RAC and Data Guard using Hitachi SAN or IBM GPFS, and the installation has become more complex since I installed the Oracle Parallel Server and had my first tested an Oracle9i RAC installation.

Last week, I was a guest at Oracle in Iselin, NJ, and attended the Oracle10g RAC Workshop using Oracle10g Release 2 (database and clusterware), a good one-day session to enhance any previous related skills. The RAC technology workshop is very well organized and includes a series of consistent ASM, clusterware, and database installation and configuration, RAC process monitoring, and fundamental manageability practices involving Grid Control, and basic command line interface, but it is not a replacement for full RAC training. Both RAC and Grid Control are foundational to the Fusion Middleware infrastructure and the Application Integration Architecture (AIA). My appreciation goes to Oracle and my congratulations to Oracle Senior Solution Architect, Ted Nanayakkara, for his great presentation work.

At the, there are very good presentations on performance tuning, and also on RAC usage for datawarehousing and Maximum Availability Architectures (MAA), with some other presentations involving fundamental architectural concepts.
