Problems solved by technology

[0012] But the above-mentioned prior art 1 and 2 also have a common defect, that is: when the new system loads data (that is, when data is switched), it needs to stop writing the data of the old system first, obtain the data slices of the old system, and then import them into Go to the new system and verify the consistency of the old and new system data
During this process, this part of the data cannot be written, resulting in interruption of business services and poor availability of business services

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Core technical scheme of the present invention comprises:

[0034] A switching method of a data service system, which includes a data switching process and a user request processing process during the switching period.

[0035] The data switching process includes: first loading the target data in the old data service system (referred to as the old system in this article) to the new data service system (referred to as the new system in this article); The primary write point of the data is switched to the new system.

[0036] The loading of the target data into the new system refers to copying the target data in the old system to the new system, and the switching of the main write point of the data refers to the switching of the business logic module capable of writing certain business data .

[0037] If a user's request is re...

Abstract

The present application discloses a switching method and system of a data business system, including: first loading the target data in the old system into the new system, and then switching the main writing point of the target data to the new system after a specified time; If a write request from the user is received during the switching period, it is decided to hand over the write request to the old system or the new system for processing according to the state of the target data of the write request in the old and new systems, and hand it over to the old system for processing Synchronize data updates to the new system; if a user’s read request is received during the switchover period, it is decided to hand over the read request to the old system or to the new system according to the state of the target data of the read request in the old and new systems deal with. Utilizing the present invention can improve the availability of business services during system switching.

Description

technical field [0001] The present invention of the present application relates to computer data processing technology, and in particular to a switching method and switching system of a data service system. Background technique [0002] The data business system is a computer data processing system that provides users with various data business services. Among the quality indicators of the data business system, the availability of system services is a key indicator. However, due to the continuous changes and updates of business requirements, when the existing data business system cannot support new business needs, it is necessary to upgrade the original data business system, which has become an inevitable problem. Especially in the Internet-based data service system, due to the faster change of business requirements, the life cycle of the Internet data service system is shorter than that of other industries, so the frequency of upgrading and transformation is higher.
