Problems solved by technology

1. The dual-machine system lacks intelligent initialization logic. After power-on, it is artificially defined which is the master and which is the slave; 2. It does not have the single-machine fault diagnosis function, which is a kind of "after-the-fact" switching, that is, only the master occurs. 3. After the two-machine switch, the time for data recovery and synchronization is long, which is easy to generate a large time "breakpoint"

Embodiment Construction

[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052] The patent of this invention aims at the problems existing in the existing dual-machine hot backup system, and proposes a method for the dual-machine complete machine-level hot backup system

[0053] (1) In view of the lack of intelligent initialization logic in the existing dual-machine hot standby system, the present invention adopts a dual arbitration strategy of "the machine that feeds the dog first" and "the machine with a small IP address is the main" for the initialization of the dual-machine system. It is used to adapt to the initial master-slave identification of dual-machine startup and almost simultaneous startup, including the following content:

Abstract

The invention provides a method for establishing a dual-computer complete machine level hot standby system, which realizes master-slave identification, dual-computer intelligent switching and dual-computer information synchronization of initialization of a dual-computer system through heartbeat information intercommunication between dual computers. The dual-computer intelligent switching comprises four parts of detection parameter state acquisition, single-computer fault diagnosis, switching interpretation and switching control. By utilizing the method provided by the invention, self-diagnosis and intelligent switching of the dual-computer system are realized, and the intelligent degree and the reliability level of the dual-computer system are improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of server database backup, in particular to a method for establishing a two-machine complete machine-level hot backup system. Background technique [0002] Dual hot backup refers to the use of two computers to back up each other and perform the same task together. When one computer fails, the other computer can take over the service, so that the system can be automatically guaranteed without manual intervention. can continue to provide services. [0003] There are two typical ways of existing dual-machine hot backup. One is that two servers pass a shared storage device (usually a shared disk array or storage area network SAN), and install dual-machine software to realize dual-machine hot backup. device, called the shared mode. Another method is through a pure software method, which is generally called a pure software method or a mirror method (Mirror). [0004] Through the dual-machine hot standby mode of...
