What is high availability?

#Availability is the degree to which an application, service, or functionality is available upon user demand. Availability is measured by the perception of an application's end user. End users experience frustration when their #data is unavailable, and they do not understand or care to differentiate between the complex components of an overall solution. Performance failures due to higher than expected usage create the same havoc as the failure of critical components in the solution. Reliability, recoverability, timely error detection, and continuous operations are primary characteristics of a highly available solution. 00:00 What is high availability? 08:07 Discussion about data guard 13:50 Oracle RAC Benefits 17:55 Why Oracle Flashback?
