Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] In the current network management system, access to the database is through standard database access interfaces, and the realization of these interfaces is provided by various database manufacturers. Taking JDBC (Java Data Base Connectivity, java database connection) interface and JBoss (a J2EE (Java 2Platform, Enterprise Edition, Java2 Platform Enterprise Edition) server) as an example, when the database application code wants to access the database, it first passes JBoss's Jca (J2EE Connectorarchitecture, J2EE Connector Architecture) obtains the implementation of the database connection interface, and then performs database access or operation, and the standard database interface of JDBC is still returned from Jca to the database application code, that is to say, the specific implementation is for the database application The...

Abstract

The invention discloses a method and device for synchronizing databases of a master network management system and a standby network management system, and quasi real-time synchronization of the databases of the master network management system and the standby network management system can be realized without using a special database synchronization tool. The device comprises the following modules: a database operation interception module, an operation log generation module, an operation log transmission module and an operation log writing-in module, wherein the database operation interceptionmodule is used for utilizing a standard interface provided by the application code layer of the database of a host machine to intercept the operation information of the database of the host machine, and the operation information comprises operation information for executing a storage procedure and operation information for updating data in the database; the operation log generation module is usedfor generating a transaction demarcation based database operation log of the host machine according to the intercepted database operation information and providing a transaction demarcation policy; the operation log transmission module is used for transmitting the database operation log of the host machine to a standby machine by using a message confirmation mechanism; and the operation log writing-in module is used for implementing synchronous writing-in of the database of the standby machine according to the database operation log received by the standby machine.

Description

technical field [0001] The invention belongs to the technical field of data synchronization, and in particular relates to a method and a device for realizing database synchronization of a main network management system and a backup network management system. Background technique [0002] With the development of telecommunications technology, the telecommunications network management system needs to provide more and more new services and new functions. At the same time, the pressure on the network management server machine and the network management server itself is also increasing. Or the phenomenon that the network management server process runs to death. In order to enable the network management server to provide services again in a short period of time after the above-mentioned abnormal situation occurs, a network management server backup plan is proposed, that is, a backup machine is deployed to run the backup program of the network management server. When the network m...
