Problems solved by technology

[0003] In the current technology, when the primary database is unavailable due to a disaster, it is usually necessary to switch the request traffic to the standby database. In this process, because the standby data does not necessarily have the data in the primary database, the same business request may be processed multiple times, which cannot Guaranteed idempotence control, resulting in bad user experience

Embodiment Construction

[0060] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.

[0061]The database unexpectedly experiences a network failure or is unexpectedly terminated abnormally, resulting in the unavailability of all services, which is called database Failover, or FO for short (usually occurs on the main database). After the disaster of the main database, it usually takes a certain amount of time to pull up the standb...

Abstract

Embodiments of the present specification disclose a disaster tolerance system, method, apparatus and device. According to the technical scheme disclosed by the embodiments of the present specification, when a service request is received and allocated to the machine room, a corresponding relationship between the machine room for processing the request and the service request is established and stored; and the service processing result is synchronized between the machine room and the mirror machine room through a data synchronization module, so that there is a full amount of data in the two machine rooms, when one machine room is in disaster, the other machine room has the data of the disaster room, and at the moment, the idempotence control of the data part in the disaster room can be guaranteed.

Description

technical field [0001] This specification relates to the field of computer technology, especially to disaster recovery systems, methods, devices and equipment. Background technique [0002] With the development of technology, in many services (for example, payment, financial related services), the requirements for disaster recovery are also getting higher and higher. [0003] In the current technology, when the primary database is unavailable due to a disaster, it is usually necessary to switch the request traffic to the standby database. In this process, because the standby data does not necessarily have the data in the primary database, the same business request may be processed multiple times, which cannot Guaranteed idempotent control, resulting in a bad user experience. In addition, it is necessary to conduct disaster drills on the system in normal times. In order to ensure the maximum user experience during the drills, it is often necessary to query business requests ...
