Problems solved by technology
[0004] In the current practical application, in the process of realizing the present invention, the inventor found that there are at least the following problems in the above-mentioned prior art: the method of starting another thread / task to be solely responsible for the heartbeat communication is less secure
For example, when the system is a multi-thread / task system, the system can receive heartbeat information regularly, but the operation of the peer system may not be normal, and it cannot provide effective services to the outside world, which makes it impossible for the active and standby systems to communicate. Learn about the real operation of the peer end in detail through the heartbeat information, and the security and reliability of the entire system is not good
From the perspective of program testability design, this kind of heartbeat communication is not conducive to the fault location of the entire dual backup system

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given and the present invention is further described in detail with reference to the accompanying drawings.
[0021] A dual backup system usually includes two systems, the master and the backup. From the perspective of the primary system, the primary system is called the local system (or local system), and the peer system refers to the backup system; if from the perspective of the backup system, the backup system is called the local system (or local system), The peer system refers to the master system.
[0022] Firstly, the relevant data tables (such as Table 1-4) that may be used in the heartbeat communication between the primary and backup systems in the embodiment of the present invention are described in advance.

This invention discloses a heartbeating communication method and a system, in which, the method includes: an opposite system organizes heartbeating frames to send them to the local end, the local system receives the heartbeating frames from the opposite side including digital information of service thread / task of the opposite system used in flagging if the service thread / task of the opposite system is normal, the local system judges if the opposite system is normal according to the heartbeating frames. This invention combines heartbeating with system service since heartbeating information in this invention does not only include master thread / task information but also include important service thread / task information of the system so as to overcome the shortcoming of separating heartbeat from system service.
Description
technical field [0001] The invention relates to the communication field, in particular to a heartbeat communication method and system between dual backup systems. Background technique [0002] A dual backup system is a system that adopts two systems, one as the main and one as the backup, during operation, and the main system provides external services. The dual backup system can automatically complete the switchover when the main system fails, and automatically upgrade the backup system to the main system to work, so as to provide services to the outside world without interruption. In order to improve the reliability of the commercial system server, merchants generally adopt a redundant design method of double backup. Heartbeat information, also known as timing handshake information, is the information that is regularly sent to the opposite end by one side (such as the main system) of the dual backup system (such as the primary system) in order to understand the operating ...
