Oracle RAC (Real Application Cluster)

Oracle RAC (Real Application Cluster) is that environment where one database runs on multiple instances ro ensure high availability of the database. Oracle RAC uses Oracle Clusterware for the infrastructure to bind multiple servers so they operate as a single system. Oracle Clusterware is a portable cluster management solution that is integrated with Oracle Database. Selecom Technology's Oracle RAC course not only covers the RAC concepts but the ASM and Dataguard also in details. Automatic Storage Managemnt (ASM) gives features of storing the database files on Disk Group to ensure data availability. Data Gurad gives the feature to mainain Primary and standby database. After colpetion of the course the trainees are ready to maintain the RAC, ASM and Dataguard.
