Method, device and system for achieving cross-computer-room updating of application program configuration data

Abstract

The invention discloses a method, device and system for achieving cross-machine-room updating of application program configuration data, and relates to big data. The method comprises the steps that when a first configuration management center background arranged in a first machine room receives application program updating configuration data sent by a configuration management center foreground, the updated configuration data is persistently written into a first database of the first machine room; the first configuration management center background synchronizes the updated configuration data to a second configuration management center background arranged in a second machine room, so that an application program of the second machine room obtains the updated configuration data through the second configuration management center background; and the first configuration management center background notifies the local application server subscribing to the configuration data updating notification message, so that the application server obtains the updated configuration data from the first configuration management center background according to the message. The synchronization of the application program configuration data among different machine rooms is realized, the real-time performance is good, and the data maintenance cost is relatively low.

Description

technical field [0001] The invention relates to the field of computer technology, belongs to big data, and in particular relates to a method, a device and a system for realizing update of configuration data of application programs across computer rooms. Background technique [0002] The application servers of the horizontal sub-databases located in different computer rooms involve some basic business configuration parameters that need to be managed. If each database server in each computer room stores a copy of these same configuration parameters, multiple copies of data may be maintained to maintain consistency. Trouble; and if the application server is directly connected to the database on a database server, it may involve the switching of multiple data sources, which will increase the management cost of multiple data sources. [0003] Some traditional methods are directly configured on the application server as a configuration file to take effect when the application is d...

AI Technical Summary

Problems solved by technology

[0004] The method of directly configuring on the application server, such as changing the configuration file first, and then reloading the content of the configuration file into the memory, maintains a high degree of complexity of the parameters, which is obviously not suitable for the synchronization of configuration parameters across a large number of servers in the computer room

Configuration parameters are persisted as independent data on the database server or cache server. Reading configuration parameters needs to be completed through network interaction, but the real-time performance of data updates between application servers, database servers, and cache servers is often not very good.
