Embodiment Construction

[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like figure 1 Shown, the hardware that the present invention relates to has web server, database server, set up database connection pool, query connection module and a plurality of business function modules in web server, client information is connected with query connection module by business function module in the server Access to the database connection pool. Due to the different query content input by the client, it is divided into multiple large query services and general query services. The above services correspond to each business function module, and the database query language is formed through the conversion and operation of each business function module and the corresponding query The connection module is connected, wherein the large query service is connected with the corresponding m large query connection units ...

Abstract

The invention discloses a limitation method of a Web server concurrent number, relating to the field of information technologies. In a three-tier system framework, the Web server accesses to a database by a connection pool; when user requests have certain large statics or inquiry, the connection pool is gradually used up by the requests, thus the whole system stops responding. In the limitation method of a Web server concurrent number, after transferring client-side information to the functional module of each service, the database connection pool is accessed by an inquiry connection module; the inquiry connection module is divided into a large inquiry connection module and a common inquiry connection module, wherein the large inquiry connection module has the maximum total concurrent number; when a user side submits a large inquiry request, if the request number is smaller than the maximum total concurrent number, one database connection is obtained from the database connection pool, and a database access request is submitted to the database server by the connection; otherwise, the user is prompted to wait. The maximum total concurrent number is set to limit large inquiry connection amount and ensure the response capability of common inquiry.

Description

【Technical field】 [0001] The invention relates to the field of information technology, in particular to a method for limiting the concurrent number of Web servers. 【Background technique】 [0002] In the three-tier architecture, the Web server usually accesses the database through the database connection pool. After a user request is submitted, the Web server finds an idle connection from the connection pool, and then uses the connection to access the database. After the access is completed, the connection is released and can be used for the next user request. When a user requests, if there are no idle connections, the request will be in a waiting state. [0003] On the one hand, the size of the connection pool depends on the frequency of user requests and the time spent on each connection, on the other hand, it is also limited by the database service capacity. When the time required for each database access is very short, the database connections in the connection pool are...
