Log analysis service real-time synchronization system under active-standby environment of databases

Abstract

The invention discloses a log analysis service real-time synchronization system under an active-standby environment of databases. The system includes a source-end database main machine, a source-end database standby machine, a source-end log analysis service main machine and a source-end log analysis service standby machine, wherein the source-end database main machine and the source-end databasestandby machine are adopted as database source ends in a database real-time synchronization system respectively, and the source-end log analysis service main machine and the source-end log analysis service standby machine are adopted as a log analysis service main machine and a log analysis service standby machine respectively. The target-end database synchronizes management services in real timein order to determine a current log service main machine according to current log analysis service priorities and the failure states of the source-end database main machine, source-end database standby machine, source-end log analysis service main machine and source-end log analysis service standby machine, wherein the target-end database is used for achieving data mapping in the current log service main machine and executing events. The real-time synchronization system of the databases can still provide continuous real-time data synchronization services without recreating or restarting aftersingle failures of the database main machine and database standby machine or database real-time synchronization system log analysis services happen.

Description

technical field [0001] The invention belongs to the technical field of database synchronization, and more specifically relates to a real-time synchronization system for log analysis services in a database active and standby environment. Background technique [0002] With the wide application of "Internet +" and "big data", the information system as its carrier is not only the key to the operation of enterprises, but also plays an important role in people's work and life, social order, national security and other aspects that cannot be ignored. role. Modern information systems have penetrated into all areas of people's lives and work. Diversified demands have led to a rapid increase in the amount of data in information systems and various types. How to manage data safely and effectively has provided IT companies with new challenges. [0003] Data storage and management is a major basis of information systems, and its security and distribution flexibility can be realized thro...

AI Technical Summary

Problems solved by technology

[0011] Although the above solution realizes the active and standby databases and real-time synchronization of the databases, when the standby machine fails, the real-time database synchronization system cannot work normally; The source database of the synchronization system is damaged, and the destination database cannot guarantee the consistency with the host database, so the service has to be interrupted
