Embodiment 1

[0031] Embodiment 1 of the present application provides a high-reliability message transmission method, such as figure 1 as shown, figure 1 It is a flow chart of a high-reliability message transmission method provided in Embodiment 1 of the present application. The method includes:

[0032] S101: Determine in real time whether the main message server is disconnected from the message database.

[0033] S102: When the primary message server loses connection with the message database, switch any one of the multiple standby message servers to be the new primary message server and the message database for message transmission.

[0034] In this application, the high-reliability message transmission system includes multiple message servers connected to the message database and front-end business applications at the same time, one of which is preset as the primary message server, and the others are used as standby message servers. Multiple message servers and message databases form...

Embodiment 2

[0037] Embodiment 2 of the present application provides another high-reliability message transmission method, such as figure 2 as shown, figure 2 It is a flow chart of a high-reliability message transmission method provided in Embodiment 2 of the present application. The method includes:

[0038] S201: Establish an application dictionary table in the message database, and add records.

[0039] Wherein, the application dictionary table includes: the IP address of the primary message server, the time stamp of successful operation, and the IP address of the secondary message server. The records include: the storage process of the standby message server's fault detection and switching host.

[0040] Specifically, in this application, an application dictionary table is established in the message database, and records are added: the IP address of the main and standby machines is allowed, the default host IP address, the time stamp of the successful operation of the main machine...

Embodiment 3

[0054] Embodiment 3 of the present application provides a high-reliability message transmission system, such as image 3 as shown, image 3 It is a schematic structural diagram of a high-reliability message transmission system provided in Embodiment 3 of the present application. The system includes: a judging module 301 and a switching module 302, wherein,

[0055] The judging module 301 is used for judging in real time whether the main message server is out of contact with the message database.

[0056] The switching module 302 is used to switch any one of the multiple standby message servers to be the new primary message server and the message database for message transmission when the judging module 301 determines that the primary message server is out of contact with the message database.

[0057] In this application, the high-reliability message transmission system includes multiple message servers connected to the message database and front-end business applications at...

Abstract

The invention provides a high-reliability message transmission method and system. The method includes the steps that whether a main message server is not in touch with a message database is judged in real time; when the main message server is not in touch with the message database, any one of multiple standby message servers is switched to be a new main message server and conducts message transmission with the message database; after failure recovery, incremental messages which are not transmitted successfully since failure occurs are retransmitted. According to the method, whether the main message server is not in touch with the message database is judged in real time, when it is detected that the main message server is not in touch with the message database, one standby message server is immediately switched into and connected with the message database so that the data can continue being transmitted, it is guaranteed that when the server fails, messages can continue being normally transmitted, and high message transmission reliability is further guaranteed through the interruption continuingly-transmitting function.

Description

technical field [0001] The present application relates to the field of electric power technology, and in particular to a high-reliability message transmission method and system. Background technique [0002] The reliability message system is applied to the business failure recovery system. In order to meet the real-time data display requirements of the power system, the reliability message system mainly solves the system requirements of high reliability and stability of the message server, which can be oriented to multiple clients and request multi-theme data concurrently . [0003] The reliability message system adopts BlazeDS message service. BlazeDS is a server-based Java remote call and Web message delivery technology, which enables the background Java application program and the Flex application program running on the browser to communicate with each other, which is a good solution The problem of real-time delivery of event messages is solved. Although BlazeDS has a c...
