21CN is the largest portal website in South China. With the continuous expansion of scale and the increase of users, the network environment is becoming more and more complicated. The servers of 21CN use different platforms, such as Linux, WinNT \ Win2000, Unix, etc .; the applications are also more complicated, including www service, Email service, FTP service, advertising system, etc .; Oracle products are used as the back-end database and news release system of 21CN Databases, and e-commerce databases, etc. In addition, the daily management of 21CN mainly includes network management, system management, database management and corresponding application software management. The management of the host system and the database system directly bears the difficult task of system performance monitoring and system performance optimization. the problem we are facing As 21CN's IT hardware and applications continue to increase, the work pressure of network system administrators is increasing; and with the rapid development of China's Internet, users are increasingly demanding network stability and reliability. A large amount of investment and increase in hardware and software have led to increased difficulty in 21CN management. The problems faced by 21CN can be attributed to the following three aspects: First of all, after application modification or long-term operation of the relational database, the client reaction time will increase and an application will run slowly. With the increasing number of 21CN access users, the existing relational database system has been difficult to adapt to user needs in terms of response speed. Secondly, in the daily management of the 21CN system, monitoring is a very important link, which is a guarantee for the stability and reliability of the system. However, the existing Oracle database of 21CN lacks solutions for database management, identification, and correction of errors, which makes the work of many DBAs cumbersome and affects the work efficiency of network management personnel. Thirdly, 21CN lacks tools to effectively monitor the overall operating status of the database, and it is unable to find many potential problems in time, which brings great difficulties to network management. Network administrators often only deal with faults after they occur, and their work is in a passive state. Sometimes, even if a fault is found, it takes a long time to find and diagnose the fault, which greatly affects the work efficiency. Solution After long-term selection, project evaluation and product testing, 21CN finally selected Youlong Technology ’s SiteView as the monitoring solution for its Web production business system. The program concentrated two of Youlong Technology ’s monitoring solutions (inside the firewall) The SiteView website monitoring solution and the Dragonwatch business process monitoring solution outside the firewall) will conduct distributed centralized monitoring and management of the 21CN Web production business system from inside and outside the network (21CN densely distributed users). SiteView is a network and website monitoring solution in the firewall provided by Youlong Technology for enterprise users. It can perform real-time monitoring of network applications, servers, network devices, and network links in the local area network, as well as distributed WAN. Centralized monitoring and management. Dragonwatch is a 24 × 7 real-time monitoring solution for web applications and e-commerce processes from the perspective of end users provided by Youlong Technology for website users. The monitoring system of Dragonwatch is distributed in more than 20 major cities in Greater China and provides The fault monitoring and performance management of the website help users to understand and locate the root cause of the failure in a timely manner, and provide decision support for the long-term operation planning of the website. Advantages of the program First of all, the SiteView system of Youlong Technology Company can collect and analyze monitoring data in time to predict and appropriately avoid the occurrence of problems; SiteView system can also implement all-weather 21CN database from different perspectives (application layer, system resources, database performance, etc.) (7X24 hours) Performance management and analysis to ensure maximum availability of the database system. Secondly, the SiteView system of Youlong Technology Company can centrally manage all operating systems running in the 21CN environment and the hardware and software resources of different manufacturers; the powerful integration function of the SiteView system can provide 21CN with cross-platform and centralized management, so that 21CN managers are freed from tedious and boring tasks. Finally, the SiteView system is cost-effective, simple to configure, and easy to use. This is undoubtedly very attractive to the 21CN company whose daily system management work is becoming more and more complicated. This is also an important factor for its use of Youlong Technology's products. 21CN SiteView monitoring principle The specific implementation and effect of the plan Manager Huang, responsible for the implementation of the project at 21CN, said that 21CN attaches great importance to providing high SLM (Service Quality Agreement) services to its mail users and Web users. The implementation of the comprehensive monitoring program of SiteView production business of Youlong Technology will further improve the quality of 21CN's mail service and other Web services, and provide a strong guarantee for the large-scale business promotion activities that 21CN will start next Greatly reduced the operation and maintenance cost of 21CN website monitoring. In view of the increasingly prominent contradiction between the current system environment and business requirements, 21CN is specifically equipped with a Win2000 server to install the SiteView system of Youlong Technology in its own hosting server IDC. With the cooperation of Youlong Technology, the 21CN technicians fully deployed the SiteView system in only half a day, realizing the monitoring of more than 500 projects of the entire 21CN system. By adopting SiteView system of Youlong Technology, 21CN Company effectively solved its own problems in system and database management.
