Oracle Real Application Clusters in Oracle VM Environments

Running today’s non-critical business applications in virtualized environments has shown to be efficient and cost saving. More sophisticated or highly available applications on the other hand were most likely incompatible with commonly used software based virtualization solutions. The availability of Oracle VM overcomes this obstacle. Providing software based virtualization infrastructure (Oracle VM) and the market leading high availability solution Oracle Real Application Clusters (RAC), Oracle now offers a highly available, grid-ready virtualization solution for your data center, combining all the benefits of a fully virtualized environment.
