Method of implementing high availability of system in multi-machine surroundings

Abstract

The invention relates to a method for implementing the high availability of the system in a multiprocessor environment. In the multiprocessor environment, one ore M standby computers correspond to N active computers and deliver the standby service for N active computers; when one standby computer corresponds to N active computers, the standby computer monitors the heartbeat with the active computer in the mode of the multicast and the standby computer monitors the working state of the active computers in the mode of the heart beating line; when the standby computer monitors that the active computer malfunctions, the standby computer takes over the work of the active computer and provides the service provided originally by the active computer to the outside so as to implement the continuous application under the circumstance that the user can not feel the service interception. The invention has the beneficial effects that the scalability of the high-availability system is solved and the high availability of the system can be realized with lower cost in a complicated multiprocessor environment having a plurality of applications, and the utilization ratio of the system resources can be enhanced.

Description

1. Technical field [0001] The present invention relates to a technical field of computer application, in particular to a system for realizing high availability of the system in a multi-computer environment [0002] Methods. 2. Background technology [0003] With the development of computer technology, information has become a very important part of the daily activities of the system. At the same time, due to the complexity and openness of the system and the diversification of the application environment, it also brings many uncertain factors to the operation of the application system. . These factors also lead to higher requirements for the security of the server. The security, stability and reliability of the business system based on this platform and the continuous operation of the system become the key to the system. [0004] Under normal circumstances, when the system cannot operate normally, we need to use manual methods to identify, analyze, recover and test the faul...

Problems solved by technology

For this mode, since each master machine must have a backup machine corresponding to it, if there are N master machines, it is necessary to deploy N backup machines accordingly to be able to serve each master machine. To provide high availability, the result is a great waste of resources. Even if Active-Active is adopted, that is, two servers each run an application, both as the main machine, and at the same time they are each other’s backup machine. The working mode also requires N / 2 spare machines
