Stateless financial information processing and backup system and method

Abstract

The present invention discloses a stateless financial information processing and backup system and method. The system comprises a state database unit, a module processor unit, and a load distribution module. The state database unit comprises a master state database module and more than one standby state database module. The module processor unit comprises more than one module processors. The module processors receive a request sent by the load distribution module, acquire state information of a user of the request from a master state database module, perform processing according to a financial information processing requirement, modify the state and information of the user after the request is processed, store the state and the information in the master state database module, then release all processing resources, and prepare to receive a next financial information processing request. With the original functions of the server maintained, almost half hardware investment is reduced; the reliability is improved greatly; and due to use of the stateless processor, the system can expand and reduce the capacity flexibly and elastically without affecting normal processing.

Description

technical field [0001] The invention relates to a processing and backup method of a financial information system, belonging to the technical field of financial information processing. Background technique [0002] In the financial information processing system of server / client architecture, the client may be in multiple states such as offline, online idle, online busy, etc., and the server needs to provide services according to the different states of the client. At the same time, the communication protocol adopted by the client server also requires the client and the server to maintain a synchronized state to ensure the normal process execution of the communication protocol. In order to achieve large capacity and reliability in the existing large-scale financial information processing system, multi-module concurrency and module hot master / standby (1+1) are usually used to achieve, such as figure 1 shown. [0003] Using the 1+1 multi-module backup method, in fact, the back...

AI Technical Summary

Problems solved by technology

[0003] Using the 1+1 multi-module backup method, in fact, the backup processor does not work in most scenarios, resulting in a maximum overall system load of no more than 50%, which is a great waste

[0004] 1+1 backup method, once both processors fail, the business cannot be migrated to other processors, and the business will be invalid

[0005] Since the user status is fixed on a pair of active and standby processors, once a user on this processor suddenly bursts out a large number of financial information processing requests, other module processors cannot share the load
