Method for applying asynchronous non-blocking of network IO to middleware of data base

Abstract

The invention discloses a method for applying asynchronous non-blocking of network IO to middleware of a data base, belongs to the technology of applying the network IO to the middleware of the data base and solves the technical problem of how to prevent thread blocking of client IO requests when the data base is accessed, how to utilize the system resources fully and how to improve the utilization rate of system resources. The employed technical scheme is that according to the method, the network IO is increased on the middleware of the data base, when the middleware of the data base processes the client IO requests, an operating system is enabled to interact with the data base, and in the interaction process, if thread resources of the operating system are occupied, for other IO operations, other resources can be allocated for interaction with the data base by the operating system without waiting for the thread resource to be released.

Description

technical field [0001] The invention relates to a technology for applying network IO in database middleware, in particular to a method for applying asynchronous and non-blocking network IO to database middleware. Background technique [0002] Database (Data base, DB) is a warehouse that organizes, stores and manages data according to the data structure. It was produced more than 60 years ago. With the development of information technology and the market, especially after the 1990s , data management is no longer just storing and managing data, but has transformed into various data management methods required by users. There are many types of databases, ranging from the simplest tables storing various data to large database systems capable of storing massive amounts of data, which have been widely used in various aspects. In the information society, fully and effectively managing and utilizing various information resources is a prerequisite for scientific research and decisio...

Problems solved by technology

[0004] With the continuous expansion of the business, the number of IO request connections of the client is increasing and the connection time is long. When accessing the database, thread blocking and connection timeout often occur, resulting in a large number of system resources that cannot be fully utilized and seriously affecting the normal operation of the application.
