HIGH AVAILABILITY DATA BASE MANAGEMENT SYSTEM AND A METHOD FOR MANAGING DATABASE USING THE HIGH AVAILABILITY DATA BASE MANAGEMENT SYSTEM, PARTICULARLY FOR CONTINUOUSLY PROVIDING A SERVICE

摘要

PURPOSE: A high availability data base management system and a method for managing database using the high availability data base management system are provided to improve service reliability by continuously providing a service even though failure occurs in a DBMS(Database Management System).;CONSTITUTION: Broker nodes(120a-120m) receive the changes of a database from an application server and tries the access to a main server node(130a). If the access is successful, the broker node transmits the change request of a database to the main server node. If the access fails, the broker node tries the sequential access to sub server nodes(130b-130n) according to a predetermined order. The broker node transmits the change request of the database to the accessed sub server node.;COPYRIGHT KIPO 2011
