Abstract


With the development of network technology and Web technology, Web-based gradual integration of the core business logic, become a new business deal with the basic platform. In a production environment, the Web application system faced with numerous customers access to complex business processes, changing user needs, performance and application performance declining affect its availability, operational efficiency, and customer satisfaction. In this paper, starting from the actual production, analysis and summary of Hunan Telecom Company is automatically activated to optimize Web applications appear in the one-year run various performance issues, from three aspects of the design patterns, data access, system performance Web applications automatically activated. Original Web application system automatically activated without adequate analysis of the system in the process of introduction of design pattern application scenarios and requirements, there are scalability and maintainability problems caused put into operation very difficult to maintain and extend. This article fully understand and analyze the original system design patterns shortcomings, MVC design pattern and Struts system framework to optimize the system. The optimization program is characterized by the Web application system is divided into logical layer, view layer and control layer., Reducing the degree of coupling between the system modules to enhance the scalability and maintainability of the system. The original Web application system automatically activated in the course, with the increase in customer visits, the system load increases, there are often slow data access, the connection is interrupted, affecting the normal use of the system. Through JDBC driver optimization, deployment and optimization, as well as the application database connection pool technology to optimize system performance, data access performance is significantly improved. The original automatic activation of Web applications in the process of the preparation of the code, not the client, Web application server, database server among data exchange, and the page data transfer implementation thoughtful, resulting in the speed of data exchange system in the course of slow to affect the operation of the system performance. In this paper, XML technology and caching techniques to improve the speed of data exchange system between the server and database server; application of JavaScript technology and asynchronous interactive technology to reduce data traffic in the network between the client and server side, using the Request object between pages data transmission. This program is effective in reducing the loss of server resources, alleviate the frequent exchange of data caused by the decrease in server performance, enhance the operation of the system performance and responsiveness. Hunan Telecom Company Web application system is activated automatically optimized and stable operation, the access throughput and response time to user requirements.
