Abstract

The invention discloses a database high availability guarantee method and system and relates to the technology of a database. The problem that the configuration and usage are inconvenient and the costis high resulting from using a dedicated product is solved. The method comprises the steps that a master server in master-backup loads a shared storage volume and provides database service through utilization of a virtual IP address of the master-backup; and when a fault occurs in the master server, a backup server in the master-backup is taken as a new master server for mounting the shared storage volume, and the virtual IP address is drifted to the backup server. The technical scheme provided by the invention is applicable to database management. A database availability guarantee mechanismwith simple and reliable configuration is realized.

Description

technical field [0001] The invention relates to database technology, in particular to a database high-availability guarantee method and system. Background technique [0002] With the development of information technology, enterprises rely more and more on information management, and the data information of various business applications is mainly stored in the database. As enterprises have higher and higher requirements for the continuity of these data accesses, in order to avoid various losses due to data interruption, high availability of databases has become the top priority of enterprise information construction. The existing high-availability solutions for databases are not common among products of different brands, and the use of dedicated products brings the problems of inconvenient configuration and high cost. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a database high availability guarantee meth...
