Embodiment 1

[0032] figure 1 It is a flow chart of a software automatic switching control method for dual-machine hot backup and disaster recovery provided by the embodiment of the present invention. The method provided by this embodiment is applied to the server host, such as figure 1 As shown, the method specifically includes the following steps:

[0033] Step S102, acquiring the working status of the target service link.

[0034]The method provided in Embodiment 1 is applied to the server host, and the executive body of the method is the soft duplex management software installed on the server host. The software proposes an automatic switchover with the service link as the main and the heartbeat link as the auxiliary. Control strategies to ensure the reliability of the system in dual-system hot standby mode.

[0035] Specifically, in the embodiment of the present invention, the server host and the server standby machine exchange heartbeat data frames (heartbeat request frames or heartb...

Embodiment 2

[0063] image 3 It is a flow chart of another software automatic switching control method for dual-machine hot backup and disaster recovery provided by the embodiment of the present invention. The method provided by this embodiment is applied to the server backup machine, such as image 3 As shown, the method specifically includes the following steps:

[0064] Step S302, judging whether there is a chance to receive a heartbeat request frame from the server host within a preset time period.

[0065] Specifically, the method provided in Embodiment 2 is applied to the server standby machine. The execution subject of the method is the soft duplex management software installed on the server standby machine. The corresponding switching strategies are designed respectively for each machine, and the soft duplex management software executes different switching control logics according to the different operating subjects.

[0066] During the operation of the system, the standby server...

Embodiment 3

[0089] The embodiment of the present invention also provides a software automatic switching control device for dual-system hot backup disaster recovery, the software automatic switching control device for dual-system hot backup disaster recovery is applied to the server host, and is mainly used to implement the above-mentioned first embodiment. The software automatic switching control method for the dual-computer hot backup disaster recovery, the following will specifically introduce the software automatic switching control device for the dual-computer hot backup disaster recovery provided by the embodiment of the present invention.

[0090] Figure 8 It is a functional block diagram of a software automatic switching control device for dual-computer hot backup and disaster recovery provided by the embodiment of the present invention, as shown in Figure 8 As shown, the device mainly includes: an acquisition module 10, a first switching module 20, a first judging module 30, and...

Abstract

The invention provides an automatic software switching control method for dual-machine hot standby disaster recovery, which relates to the technical field of communication, and comprises the following steps: after the working state of a target service link is obtained, if the target service link is switched from an effective state to a failure state, switching a server host to a new standby server, and determining whether a heartbeat response frame of the standby server has an opportunity to receive within a preset time period, and if so, sending a request for switching to the new server host to the standby server so as to switch to the new server host. In the method provided by the invention, the server host and the standby server can perform heartbeat data frame interaction based on the following links: the main service link, the standby service link and the heartbeat link, and based on the three links and the switching control strategy, the duplex switching times can be reduced, the reliability of a single server node is improved, and the switching efficiency is improved. Therefore, the reliability of the information application system is improved, and the technical problem of low reliability of a dual-machine hot standby control method in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a software automatic switching control method for dual-machine hot backup and disaster recovery. Background technique [0002] In the information application system, in order to avoid the business interruption of the entire system caused by the abnormality of a single server node, the key nodes are usually configured in the dual-machine hot standby mode, that is, two servers are configured on a single node, the main machine and the standby machine, and the main machine and the standby machine are configured. Install general-purpose duplex software (such as keepalive software) on the standby machine. In this working mode, during normal work, the main server is in the working state, and the standby server is in the standby state; when the main machine is abnormal, the standby machine will automatically switch to the main machine , so as to ensure business continuity. However...
