Switching method and switching system for data service systems

Abstract

The invention discloses a switching method and a switching system for data service systems. The switching method comprises the steps that target data in an old system are loaded to a new system, and the main writing point of the target data is switched into the new system after assigned time; if writing requests of users are received in the switching period, whether the writing requests are handed to the old system to be processed or the new system to be processed is determined according to the state of the target data of the writing requests in the new system and the old system, and the data are synchronously updated to the new system when the writing requests are handed to the old system to be processed; if reading requests are received in the switching period, whether the reading requests are handed to the old system to be processed or the new system to be processed is determined according to the state of the target data of the reading requests in the new system and the old system. By means of the switching method and the switching system for the data service systems, the service usability of services when the systems are switched can be improved.

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.

Problems solved by technology

[0012] However, the above-mentioned existing technologies 1 and 2 still 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
