Problems solved by technology

[0003] In related technologies, distributed database systems are generally used in network management products, that is, the disaster recovery and backup technologies developed and used are all carried out in distributed database systems, because there may be multiple databases providing database services in distributed systems The server (also known as a node, or simply called a database), therefore, in the database operation, the operations of each node may not be completely consistent (for example, a node's network has a temporary problem, which may cause inconsistency in the operation at this time) , which may lead to more serious problems, such as inconsistencies in the backup data state that cannot be restored, complicated backup and restore operations that are error-prone, and difficult maintenance of backup files.

Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] figure 1 is a flowchart of a method for providing database services according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0023] Step S102, multiple database servers form a cluster;

[0024] Step S104, multiple database servers in the cluster serve as a node to provide a unified interface;

[0025] In step S106, a database server in the cluster provides database services externally through the above-mentioned interface.

[0026] Through the above steps, in a cluster with multiple database servers, only one database server provides services, thus avoiding problems caused by multiple database servers providing services in ...

Abstract

The invention discloses a method for providing database service and a database system. The method comprises the following steps that: a plurality of database servers form one cluster; the plurality of database servers in the cluster serve as one node to provide a uniform interface for the outside; and one database server in the cluster provides the database service for the outside through the interface. The reliability of the database system is improved by the method.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method for providing database services and a database system. Background technique [0002] In network management products, data preservation and restoration have high requirements on data security and real-time performance. How to establish a backup system with complete functions while managing the existing equipment well has become an important problem to be solved by network management products. [0003] In related technologies, distributed database systems are generally used in network management products, that is, the disaster recovery and backup technologies developed and used are all carried out in distributed database systems, because there may be multiple databases providing database services in distributed systems The server (also known as a node, or simply called a database), therefore, in the database operation, the operations of each node may not be completel...
