Method for rapidly switching intra-city dual-active framework

The invention relates to the technical field of a database and discloses a method for rapidly switching an intra-city dual-active framework. The method comprises the following steps of (1) construction of first sharing storage equipment; (2) construction of second sharing storage equipment; (3) data operation: when a switching operation occurs, executing a switching command, and adding the sharing storage equipment of a second database cluster registration service resource into the database; executing a copy command, backing-up the data from the sharing storage equipment of a first database cluster registration service resource into the sharing storage equipment of the second database cluster registration service resource; and (4) checking: restarting the database, and checking a database cluster state situation. According to the method for rapidly switching the intra-city dual-active framework, on the basis of the intra-city dual-active framework, rapid switching under the intra-city dual-active framework is
