Method for managing and switching high availability multi-machine backup routing table

Abstract

The invention relates to the technical field of security electronic system data backup control, in particular to a method for managing and switching a high availability multi-machine backup routing table. The method is characterized in that a cluster computer system is composed of a plurality of transaction hosts, and the transaction hosts receive and process orders through a middleground access gateway and return processing results to a foreground access node through the middleground access gateway. The hosts communicate through networks, a file system is read, written and accessed through a shared storage device, consistency data among the hosts is coordinated and synchronization among the hosts is conducted through distribution lock service, and a node failure and node adding notice is obtained through cluster member management service. The method is applicable to a cluster system, a cold backup device is added, an order routing table capable of defining host logic reciprocal relation flexibly is provided, high availability, concurrent processing of various items, handling capacity, delay response, a switching time index of the system remain a level close to an original one-host one-backup-device mode, and cost is low.

Description

[technical field] [0001] The invention relates to the technical field of security electronic system data backup control, in particular to a management and switching method for highly available multi-machine backup routing table distribution calculation, multi-machine coordination and central distribution. [Background technique] [0002] The stock exchange provides a public trading platform for the securities market. The securities core trading system is a platform system for real-time bidding matching of securities products, also known as a bidding matching platform, which is a key business system. [0003] The bid matching platform is composed of a multi-host cluster responsible for computing and processing in the background, a middle-end access gateway, and a front-end access node. Because the bid-matching platform needs to deal with more than 100 securities companies, thousands of business departments, and 90 million investors from across the country , an average of thous...

Problems solved by technology

[0006] Secondly, improve the host connection mode. Currently, the securities industry mainly uses a hot backup mode of one master and one backup, such as a dual-machine backup method disclosed in the domestic patent CN1366242A. It supports synchronous operation between the master and backup machines, and uses the management layer between the application layer and the system layer to instruct operations such as IP switching between the master and backup machines, file and registry mirroring, etc., but this mode is not suitable for information data that is huge and updated The extremely fast stock trading system is prone to problems such as double point failure, delayed response, and low throughput

[0007] Thirdly, add a cold standby machine as a supplement to the hot standby mode of the host, restart the cold standby machine after the hot standby switch takes effect, and add the cold standby machine to the background cluster, which can improve the overall redundancy of the system and provide flexible system operation for the securities industry. It can respond quickly after failover and re-insure the system. However, in the existing system of the securities industry, this addition process will have a significant impact on the working trading host. The existing system of the securities industry is added to the cold standby machine The main way is to shut down the system for maintenance, and it is not possible to start adding cold standby machines during the mid-day trading period
