Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The present invention designs three layers, provides infrastructure for lightweight hot standby real-time synchronization, faces two layers, realizes two kinds of synchronization interfaces respectively, one is the synchronization of network management control data structure NSM, and this data structure is to realize each The basis for application modules. The second type is the synchronization between application modules. This type of module can be dynamically loaded and removed according to application requirements. The synchronization interface designed for this is oriented to each application module. They apply unified data interface rules and synchronization Mechanism, you only need to design the corresponding data structure according to the rules of each application module.

Abstract

The invention relates to a light-weight hot standby system synchronization method. A system comprises application module layers, a network controlling and managing layer and a basic platform layer. The basic platform layer comprises a hardware layer, an operation system and HSL hardware packaging and is used for providing a basic platform for the network controlling and managing data layer. NSM synchronization is adopted in the network controlling and managing data layer and used for connection of the application module layers. The application module layers are synchronized and used for being dynamically loaded and unloaded according to application demands. The method includes the steps that firstly, the application state of a device is detected, and application information is obtained; secondly, information of a main board and a standby board of the device is detected, and after the main board and the standby board are selected, the system is notified; thirdly, the system starts corresponding programs and synchronizes the main board and the standby board; fourthly, when the main board shuts down, the standby board takes over the main board immediately, the standby board is promoted to be a main control board, the system is notified, and the needed programs are started. The light-weight hot standby system synchronization method relieves the burdens of the system, simplifies scrambling resources by double hosts, shortens switching time and is good in usability and few in occupied resource.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method for synchronizing a lightweight hot standby system. Background technique [0002] The high-availability cluster adopts redundant hardware and special software, which can quickly restore the system when a problem occurs, greatly improving the availability of the system. The heartbeat mechanism is the basic technology of high-availability clusters. The heartbeat periodically detects the working status of the node machines in the cluster, and when the working status of the node machines changes, it can notify other components of the cluster software. The emergence of high-availability clusters is to make the overall services of the clusters as available as possible, thereby reducing losses caused by computer hardware and software error-prone. It minimizes the impact of software / hardware / man-made failures on the business by protecting the user's business prog...
