Multi-computer room deployment system and cross-computer room business data processing method

Abstract

The invention discloses a system deployed in multiple computer rooms and a cross-computer-room business data processing method. The system comprises a main computer room and a standby computer room, wherein the main computer room comprises at least one business server, and a main cache database and a main database used for storing business data, the standby computer room comprises at least one business server, and a standby cache database and a standby database used for storing the business data; the business data are synchronized bidirectionally between the main cache database and the standby cache database, the business data are synchronized bidirectionally between the main database and the standby database; the at least one business server of the standby computer room is used for reading the business data from the main database when receiving a business data reading request, and writing the business data into the main database when receiving a business data writing request. In the system, when the business data are synchronized bidirectionally between the main database and the standby database, the business data of the main database are taken as principal, so that the data of the standby database and those of the main database can keep high consistency.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a multi-computer room deployment system and a cross-computer room business data processing method. Background technique [0002] With the increasing popularity of network services, it is often necessary to store some commonly used data (such as business data, etc.) on servers in multiple computer rooms at the same time. For example, in order to provide the same service to users all over the country, three computer rooms are set up in Beijing, Guangzhou, and Tibet respectively. Users can access the required services through any node in the computer room. Generally, users access the nearest node in the computer room That's it. At this time, the data stored in the computer rooms in Beijing, Guangzhou and Tibet are the same. In addition, sometimes in order to prevent the service interruption caused by the server hanging in one computer room, multiple computer rooms storin...

Problems solved by technology

[0003] In the above situation, the data in multiple computer rooms needs to be consistent. Once the data in each computer room is inconsistent, it will affect the normal use of users.

Due to frequent changes in business data, once the data in a computer room is changed, data inconsistency will occur if other computer rooms are not updated synchronously in time. Therefore, there is currently no effective mechanism to ensure that the data in multiple computer rooms strong consistency
