Oracle by Example - Oracle Database 10g on VMWare/RAC

Availability

Oracle Real Application Clusters (RAC) 10g is an option to the Oracle Database 10g Enterprise Edition. Oracle RAC is a cluster database with a shared cache architecture that overcomes the limitations of traditional shared-nothing and shared-disk approaches to provide a highly scalable and available database solution for all your business applications.

Human errors are generally considered the biggest single cause of down time, and Oracle Database 10g is a breakthrough release for human error correction by means of its greatly enhanced flashback capabilities. Flashback is a capability that lets an administrator “rewind” activity on the database. Flashback can be performed at the row, transaction, table or even database level. Point-in-time recovery of an error performed a few minutes ago can be performed in a few minutes; no restoration of a backup and roll forward is required, thereby resulting in faster up-time.

In this section of the Oracle by Example Series, the following tutorials have been written specifically for a RAC environment. You can make use of these tutorials by installing VMWare and loading a VM with the Oracle environment.
