Embodiment Construction

[0033] The present invention relates to a dual-core controlled image backup method. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods, but it is not intended to limit the present invention.

[0034] In this implementation case, the backup working principle is shown in Figure 1. In this embodiment, the core service provides an interface for running data query and data change notification. When the mirror service starts, it queries the active core service for all running real-time data, and subscribes to the data change notification event of the core service during the running process. Keep data in sync with core services. Please refer to Figure 2, the steps are as follows:

[0035] Step A-1: ​​The mirror service sends a login request to the standby core service;

[0036] Step A-2: The standby core service returns the login failure information to the mirror service;

[0037] Step A-3: If the...

Abstract

The invention relates to the communication technology field, especially relates to two-core control mirror backup method. The method adopts the mechanism of the mirror heat backup, the core service allocates two independent mirror services, and it stores the control data for the core service and provides the data analysis and data acquisition for the core service, and at the same time, it shares the data service of core service to reduce the work of core service. In the system without adopting two-core backup system, when the single core control sever happens fault and refresh resetting, it can obtain the running information from the mirror service to keep the system running cautiously. For the non-core control module, if it needs heating backup or sharing load, the main core service coordinate and control it. The invention adopts the mirror service to help the core service to finish the data backup and data analysis to improve the reliability and the flexibility of whole system.

Description

technical field [0001] The invention belongs to the technical field of software communication, and in particular relates to a dual-core control image backup method of a core control system. Background technique [0002] The traditional core control system often adopts a single dual-core control system. In order to complete the switching of the main and backup systems, the two core control systems not only complete the heartbeat synchronization, but also determine the current main and standby status; For real-time data, in order to prevent the main-standby switch from affecting the existing business, the real-time data synchronization of the two core control systems must be performed in real time. If the synchronization time is too short, the working efficiency of the two core control systems will be greatly affected. If the synchronization time is too long, seamless switching of all existing services cannot be guaranteed. [0003] However, in the core control system of the ...
