CDC-TYPE DB REPLICATION SYSTEM IN NETWORK SEPARATION ENVIRONMENT IN WHICH NETWORK BETWEEN SERVERS IS DISCONNECTED

Title:

CDC-TYPE DB REPLICATION SYSTEM IN NETWORK SEPARATION ENVIRONMENT IN WHICH NETWORK BETWEEN SERVERS IS DISCONNECTED

Document Type and Number:

WIPO Patent Application WO/2022/250292

Kind Code:

A1

Abstract:

The objective of the present invention is to provide a CDC-type DB replication system in a network separation environment in which a network between servers is disconnected, the system enabling DBMS replication by transmitting only data, of which security verification has been completed, through a server for a separate security verification that is not a direct communication method between CDC SW agents in a network separation environment in which direct communication between the SW agents is impossible. To achieve the objective, the CDC-type DB replication system in a network separation environment in which a network between servers is disconnected, according to the present invention, comprises, in the network separation environment in which a network between servers is disconnected, a source DBMS, a security verification system for performing security verification on change data transmitted from the DBMS, and a target DBMS for receiving, from the security verification system, the change data of which security verification has been completed.
