When storage indexes kick in, the number of blocks that need to be returned from the storage cells drop dramatically. Since the storage cells can provide many blocks very quickly most of the time in big accesses is usually loading that information into the compute nodes. But storage indexes don't always kick in the way…

One of most commonly used architectures for in a database as a service (DBaaS)  cloud is virtualizing database. In this architecture, all the Oracle databases are running on virtual machines. To provide a database service, virtual machines with database preconfigured are dynamically provisioned. This session will discuss the two most commonly used virtualization methods: Oracle VM and VMware.
