DISASTER RECOVERING METHOD WITH DUPLICATED APPLICATION SERVERS AND A SYSTEM USING THE SAME, CAPABLE OF RESOLVING THE INCONVENIENCE OF SYSTEM USERS

摘要

PURPOSE: A disaster recovering method with duplicated application servers and a system using the same are provided to duplicate the application server of a disaster recovery (DR) system, thereby significantly reducing time required for disaster recovery.;CONSTITUTION: A main center (130) processes a client request. If the main center cannot process the client request, a DR center (340) processes the client request. The DR center includes a DR center application server (342) which is an application server connected to the DR center. If the main center can process the client request, a load balancing part (120) transmits the client request to a main center application server. If the main center cannot process the client request, the load balancing part transmits the client request to the DR center application server.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Client; (120) Load balancing part; (130) Main center; (132) Main center APP server; (134) Main center DB; (134a) Main center request processing part; (134c) Main center storage part; (144) DR center DB; (144a) DR center request processing part; (144c) DR center storage part; (300) APP server dualization disaster recovering system; (340) DR center; (342) DR center APP server
