Method and device for switching main and standby servers

Abstract

The invention relates to a method and device for switching main and standby servers. The method comprises the following steps: S1, monitoring a heartbeat packet sent by the main server and operation performance parameters of the main server by the standby server when the main server is in an operation state; S2: judging whether the standby server receives the heartbeat packet, if so, executing step S3, and otherwise executing step S4; S3, judging whether numerical values of the operation performance parameters of the main server exceed preset values by the standby server, if so, executing step S4, and otherwise executing step S1; S4, judging whether the standby server is connected with a preset server, and if so, executing step S5; and S5, switching the main server to the standby server according to a preset switching rule, and sending a prompt signal. According to the method and device provided by the invention, the main server is quickly switched to the standby server before a fault of the main server by means of the real-time monitoring of the main server by the standby server, thereby improving the efficiency of switching the main and standby servers, in addition, the method and device provided by the invention has the advantages of low cost and high flexibility.

Description

technical field [0001] The present invention relates to the technical field of simulation, and more specifically, to a method and device for switching between active and standby servers. Background technique [0002] The simulation system generally includes multiple subsystems, each of which runs on one or more servers, and the entire system is deployed in a distributed manner. Under normal circumstances, multiple simulation systems share a set of spare parts. When encountering important application scenarios (such as operation drills and qualification examinations), the spare server will be used as a cold standby server for a system. When a problem occurs with a server in operation, the maintenance personnel must manually reset the corresponding Access the system, switch to the standby server, and ensure the normal operation of the system. This switching method has three disadvantages. First, the backup server has not been connected to the operating network before, so manu...

Problems solved by technology

This switching method has three disadvantages. First, the backup server has not been connected to the operating network before, so manual access to the network is error-prone and takes a long time to switch. The abnormality of the main server causes the serious failure of the entire simulation operation to be discovered and processed; third, the standby server is in a state of overcooling and cannot synchronize the state of the main server in real time. When the failure of the main server storing simulation process data causes a downtime, only Can reset the entire simulation operation process, seriously affecting the simulation service
