Abstract

The invention provides an HAC (High Availability Cluster) system, a warning method based on the HAC system and a warning system based on the HAC system. When the HAC system, the warning method and the HAC system are used, warning information is simultaneously stored in a first main database and a first auxiliary database of a master node and second auxiliary databases of each slave node. Under the condition that a database connection fault does not occur, the warning information stored in each database is consistent. The warning information can be obtained from the database of the currently accessed node no matter whether the node currently accessed by a user is a master node or a slave node. Even when the database of the master node or the slave node fails, the user can also obtain the warning information from the second auxiliary databases of any one slave node, so that corresponding dealing measures can be taken in time according to the obtained warning information; the normal operation of the HAC system is ensured; the loss since the dealing measures are not taken in time is effectively avoided; and the system performance of the HAC system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of computer clusters, in particular to a high-availability cluster system, and also relates to an alarm method and an alarm system based on the high-availability cluster system. Background technique [0002] With the rapid development of communication network technology, the requirements for server availability in key fields such as telecommunications, finance, and e-government are getting higher and higher. Stopping service due to server failure will cause huge losses. High Availability Cluster (HAC) ) system can greatly improve the availability of the system, and minimize the impact of failures caused by software, hardware, and human beings on the business. [0003] A high-availability cluster system is a system that is monitored by cluster software and has multiple servers that are mutually redundant. This system can provide business continuity through the fault monitoring and fault handling capabilities...
