Oracle Database High Availability
Databases and the Internet have enabled worldwide collaboration
and information sharing by extending the reach of database
applications throughout organizations and communities. Both small
businesses and global enterprises have users all over the world who
require access to data 24 hours a day. Without this data access,
revenue and customers can be lost, penalties can be owed, and bad
press can have a lasting effect on customers and a company's
reputation. Building a high availability IT infrastructure is
critical to the success and well being of all enterprises in
today's fast moving economy.
One of the challenges in designing an HA solution is examining
and addressing all the possible causes of downtime. It is important
to consider causes of both unplanned and planned downtime when
designing a fault tolerant and resilient IT infrastructure.
Unplanned downtime is primarily the result of computer failures or
data failures. Planned downtime is primarily due to data changes or
system changes that must be applied to the production system.
