Problems solved by technology

[0004] However, if the shared disk is incompatible with the standby database or the shared disk fails during the dual-server switchover process, both the primary database and the standby database will be unable to continue responding to user requests, which will not only make data security performance is not guaranteed, and the user's business request cannot be met in time

Embodiment Construction

[0079]The embodiment of the present application provides a master-slave database switching method and related equipment, which are used to configure the respective disk group resources in the first database and the second database, and the business plane floating The switching of IP and the switching of the roles of the master database and the slave database no longer need to take the disk group resources and database resources offline from the master database and then go online from the slave database, which avoids the gap between the disk and the database during the dual-machine switchover process. The problem of incompatibility, and the situation that the user's request cannot be responded to due to the failure of the shared disk is avoided.

[0080] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0081] The terms "first", "second" and the like in the specification and claims of the present application and the abov...

Abstract

The embodiment of the invention discloses an information processing method and terminal equipment. The method is used for respectively configuring respective disk pack resources in a first database and a second database. In the dual-computer switching process, the switching of the service plane floating IP and the switching of the roles of the master database and the slave database are involved, so that the problem of inadaptation between the disk and the databases in the dual-computer switching process is avoided, and the data security is improved. The embodiment of the invention provides a master-slave database switching method, and the method comprises the steps that a first host releases the binding of a first database and a service plane floating IP address under the condition that the first database meets a dual-computer switching condition; the first host switches the first database from the master to the slave; and the first host sends indication information to the second host,and the indication information is used for indicating that the second database is switched from slave to master and starting the service plane floating IP address on the second database.

Description

technical field [0001] The present application relates to the field of databases, in particular to a database switching method and terminal equipment. Background technique [0002] With the continuous development of computer technology, users send more and more business requests through the database client, and correspondingly, the database server receives more and more business requests. When a failure occurs on the database server side, the business request sent by the user will not be responded to. [0003] In order to avoid the occurrence of the above situation, in the prior art, a primary database and a standby database are provided at the database server side at the same time, and a set of external shared disks is provided outside the primary database and the standby database. When the primary database is in normal use, the standby database is closed, and the primary database accesses the data in the shared disk, and responds to the business requests sent by users bas...
