Pro Oracle Database 10g RAC on Linux

Real Application Clusters and the Grid architecture are Oracle's strategy for scaling out enterprise systems to cope with higher and higher workloads and more and more users. The premise of Grid is simple: it works just like a utility (e.g. electricity) grid. You don t care which "station" you get your data from as long as you get it, and if one station goes down then it s just fetched from somewhere else without the user being any the wiser. As demand grows you just add another cheap 2-CPU Intel machine (running Linux) to the cluster.
