RAC

Oracle Real Application Clusters (RAC)

The following documentation is a guide on how to install, configure and administer Oracle 10g Real Application Clusters (RAC).

The site has been comprised of reading the following books and real world experience, if you are new to Oracle RAC I highly recommend that you should purchase these books as it contains far more information than this web site contains and of course the Official Oracle web site contains all the documentation you will ever need.

Please feel free to email me any constructive criticism you have with the site as any additional knowledge or mistakes that I have made would be most welcomed.
