DATABASE SYSTEM AND METHOD FOR PROXYING DATA REQUEST SIGNAL

摘要

PROBLEM TO BE SOLVED: To improve promptness of a response to a data request signal in a database system.SOLUTION: A resource state notification/notification information management function unit 13 manages the resource utilization condition information and data synchronization state information notified from other database servers. When the received data request signal is a data reference request and the local database server 1 is in a slave state during data synchronization, a request signal relay function unit 15 refers to the resource utilization condition information and data synchronization state information of other database servers and proxies to a data synchronized database server having a large amount of excess resources.SELECTED DRAWING: Figure 1
