Abstract

The invention provides an automatic switching method and system. The automatic switching method comprises the steps that the automatic switching device monitors the service state of an application server in real time; when the automatic switching device monitors that the application server stops providing the service for a client side, the automatic switching device sends a switching instruction to the application server and sends a notification message to a standby server, wherein the switching instruction is used for switching a current configuration option, and the notification message is used for switching the current configuration option; the standby server switches the current configuration option to a first preset configuration option according to the notification message and provides the service for the client side, wherein the first configuration option is used when the application server provides the service for the client side. According to the automatic switching method and system, the number of system devices is reduced, the complexity degree is reduced, the switching can be automatically completed, the switching process is efficient and safe, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of distributed systems, in particular to an automatic switching method and system applied to standby servers. Background technique [0002] The security inspection system includes security inspection equipment installed at the workstation at the security checkpoint. The security inspection equipment is used to scan the human body or the items carried, and send the scanning results to the security inspection management system for processing, so as to prevent the risks brought by contraband. The security inspection management system includes security inspection Distributed management system or centralized security check management system. In normal mode, the security check distributed management system generally has two sets of redundant servers, core switches and some non-universal clients. One set is used in the application environment, and the other is used as a backup environment. The backup environment needs to be ...
