Business Continuity and High Availability

Business Continuity is the ability of an enterprise to provide its functions and services without any lapse in its operations. High Availability is the highest possible level of fault tolerance. To achieve business continuity, systems are designed with multiple servers, multiple storage, and multiple data centers to provide high enough availability to support the true continuity of the business. To establish and maintain such an environment, data needs to be moved between these multiple servers and data centers, which is easily done using Oracle GoldenGate. know more at Oracle golden gate online course
