Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0018] An embodiment of the present invention is used in the network of the State Grid Corporation of China. Through this embodiment, data synchronization between databases of various business systems in the electric power industry is completed. The technical solution adopted in this embodiment mainly includes two parts: firstly, the integration and transmission of the log is based on a "transaction" as a unit, and there is no need to deal with a complicated "rollback" mechanism. Using this technology, it can better maintain the consistency and integrity of data replication while having high performance. Secondly, the instant message bus is selected for the transmission of database logs. Because the State Grid Corporation plans to use the instant message bus subsystem for data transmission, the data security can be guara...

Abstract

This invention discloses a transaction granularity synchronizing method of a database, relating to the field of power system informatization and automation. The method comprises the following steps: using ''transaction'' as a unit of the integration and transmission of a log; without processing a complex ''rollback'' mechanism, performing efficient database synchronization on the premise of ensuring consistency and integrity; and applying an instant message bus to ensure the data security and have a higher transmission speed simultaneously. The method provided by the invention is beneficial for improving the efficiency of the synchronous replication of the database, and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of power system informatization and automation, and mainly relates to a method for real-time synchronous data exchange between databases. Background technique [0002] With the construction of the SG-ERP project of the State Grid Corporation of China, the State Grid Corporation of China has built relevant application systems in the aspects of three sets and five centers, two centers, information platforms, comprehensive analysis and decision-making, etc., and the information system architecture is more complex. In order to ensure data consistency between different business systems, the problem of data exchange between business systems must be solved, and real-time synchronization between business system databases is one of the feasible ways to solve this problem. [0003] The traditional principle of database replication is to extract the redo log (redolog) or archive log (archive log) of the source database, then tra...
