Application of Oracle 9i Data Guard to the Waterpower Scheduling Automation System

A waterpower scheduling automation system is an important production system in the operation of a power grid. The requirements of the system for database backup, data integrality, and real-time and concurrent access performance are high. A new task is to make use of the advanced functions provided by the commercial database to establish a stable, reliable and efficient water scheduling automation system. Several popular database application schemes are analyzed and compared, and the Oracle Data Guard technique is chosen for the construction of the waterpower scheduling automation system, which is good in performance, high in availability, low in cost and convenient in maintenance.
