Multi-machine hot standby method and system

Abstract

The invention provides a multi-machine hot standby method and system. The method is applied to a system comprising a hot standby system and a subscription database. The system comprises hot standby modules respectively corresponding to n board cards, at least one service process runs on each board card. The method comprises the following steps: the hot standby system determining a main board cardand n-1 slave board cards in the n board cards; the hot standby system subscribing registration information of the service processes on the m subscription database subscription board cards corresponding to the m service processes on the n board cards; the hot standby system receiving m pieces of service process registration information sent by the m subscription databases respectively; the hot standby system establishing a hot standby relationship between the hot standby module of the main board card and the hot standby modules of the n-1 slave board cards according to the m pieces of serviceprocess registration information; and the hot standby system acquiring mode identifiers in the m pieces of business process registration information, and manages the n board cards according to the mode identifiers and the hot standby relationship. And hot standby without service perception can be realized.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and system for multi-computer hot backup. Background technique [0002] In today's era, with the rapid development of the Internet, the scale of the network and the rapid expansion of the application field, the network has penetrated into all aspects of our lives and has become an indispensable part of social life. As its application is becoming more and more extensive, the communication and exchange between enterprises and individuals cannot be separated from the use of the network. People's dependence on and application of the network is also increasing, and the requirements for the stability and reliability of the network are also getting higher and higher. . In this case, every minute of temporary suspension of equipment functions and temporary interruption of services may have a great impact and bring huge losses to all walks of life. Therefore, the high reliabil...

Problems solved by technology

[0005] In the above traditional backup scheme, after the non-master device establishes a redundant backup relationship with the master device, the business process on the global master device needs to perform a backup action, and at the same time, it needs to wait for the relevant notification from the hot standby system to perform the backup process. You need to care about the entire hot standby logic during operation, which affects the design of business functions

On the other hand, if the business process is restarted, a complete backup process needs to be performed again. If the process is on the global master device, it even needs to be backed up N times, which seriously wastes bandwidth between topologies and wastes CPU resources.
