The Application and implementation of Oracle Database High Availability in Business Support System
Abstract
The database is the kernel of the Business Support System of telecommunications, The Oracle database has been widely used in Business Support System of telecommunications. The business features of Telecom request 7*24 hours service. Have to be compatible in the fierce market, improve the level of telecommunications services, enhance the core competitiveness, Therefore the database system's high availability and reliability call for a very higher level.
Oracle database itself provides a lot of high availability technologies, how to choose the right technologies and combine them effectively and Structures suitable for the telecommunications industry, the characteristics of the availability of the database. Many telecom companies are being or will soon face the reality when starting to establish the course of business support systems.
In this paper, I will use the China Mobile's Business Support System as the background, from the perspective of engineering application, to analysis of the Oracle's automatic memory management, clustering, data guard and backup as well as recovery technology applications such as high availability status and implementation.
Fact has proved that China Mobile business support system through the application of these systems Oracle High Availability technology, system performance has been greatly improved, the failure is also greatly reduced And its’ the same to the incidence of the failure recovery time, which suggests it has achieved the purpose of High Availability.
Through the discussion and study of the automatic memory management, clustering, data protection and backup and recovery Oracle high-availability technologies such as exploration and research, I hope it may be helpful for other telecommunications companies in the establishment of business support systems.
Key words: Oracle, Database, High Availability, Business Support System
