The data stored in the databases of your organization's computer systems is extremely valuable. In many cases, this data represents your most valuable asset. Protecting this asset is crucial for any Oracle site.
As a DBA, system administrator, or system architect, you will probably have to use a variety of options and techniques to ensure that your data is adequately protected from a catastrophe. Of course, implementing proper backup operations is the foundation of any disaster-prevention strategy, but there are other ways to avoid a variety of disasters, from simple disk failures to complete failure of your primary database site.
Availability can mean different things for different organizations. For this discussion, we will consider a system to be available when that system is both up which means that the database can be accessed by users and working which means that the database is delivering the expected functionality to users with the expected performance. Oracle high availability features are called Oracle HA.
Businesses have always depended on their data being available. With the increased use of the World Wide Web as a way to share data with outside world, database failures can have an even more dramatic impact on business. Failure of web-based system with links outside a company's employees are unfortunately, immediately visible to the outside world and can seriously affect the company's financial health as well as its image and the loyalty of its customers. Consider the Internet service offered by UPS and FedEX to share package status and tracking with their customers. As customers come to depend heavily on a service offered over the Web, interruptions in that service can cause these same customers to move to competitors.
