There has never been such a big fight on other projects, because the magnitude of data cannot be reached. This time, we have organized a special team to be responsible for the performance test and optimization of Datong Thermal. The test is divided into performance troubleshooting stage and stress test stage. Performance troubleshooting stage: test all the functions of the system according to the test cases, find out the functions that lead to the increase of system resources and slow response, record them, and optimize the performance problems exposed in this stage. Stress test phase: perform concurrent stress test on common functions. In this phase, we focus on several main performance indicators: response time, throughput, and system resource consumption. First, the common functions that need stress testing are determined and the test scripts are sorted out. Determine the test concurrency of 5,10,15,30,50 according to the actual use of the customer, and simulate 5010015030500 people using the system at the same time. Lock the functions with performance problems according to the concurrency test results, and determine how to allocate the resources of each virtual machine and how many Tomcat clusters to create. On site training At the beginning of August, Director Xu called me to the office to discuss the system training.

Task! After half a year's hard work, it finally becomes shining today! The leaders of Datong Thermal Power Business Department were also satisfied with the effect of the project launch. The reconciliation and financial statements of the day were very accurate, and everyone was very happy. A feeling of "see the sun through the clouds, and see the moon through the clouds" slowly spread in our hearts. On site support Since August 25, I have successively applied to the company for resources to be sent to Datong Thermal Power. The purpose is very clear, which is to protect the stable operation of the project. By August 31, our team was in place: Yang Gong, the R&D engineer, was responsible for the rapid handling of software emergencies, and Han Gong, the implementation engineer, was responsible for the stable operation of Huadu Business Hall and the charging system.

And discuss the key issues. In general, Datong thermal customers have a great cooperation, and the communication staff have a strong sense of responsibility and enthusiasm. Everyone adheres to the idea of exposing problems and solving problems as soon as possible, actively promotes the project progress, and does not let problems hide until the project goes online. I also got a lot of user stories from customers, which are very valuable. On April 10, the second week of project implementation, the colleagues in charge of data migration began to be stationed. Datong Thermal's customer base data is about 600000, and the historical data of 7 years constitute a large amount of data since I started the project, so we attach great importance to data. One step of data migration is data analysis.

Hainan intelligence Property charging software The division had arrived two days earlier and waited. In the afternoon, we pulled the hardware into the computer room under the guidance of the Information Department. The machine room of Datong Thermal Power is very professional. The outer room is the monitoring room, the inner room is the hardware equipment, and the middle is a large glass wall. The temperature and moderation of the machine room can be easily seen through the glass. The door of the computer room is identified by fingerprint, and only the personnel of the information department can enter and exit. After entering the computer room, there were 12 cabinets in order, and the wiring was neat and not messy. We put the server on the shelf together with our brother from the Information Department, and then we went on wiring. There are 5 servers in this project, each server has 8 gigabit ports and 2 10 gigabit ports, that is to say, each server needs 8 network cables and 2 optical fibers. Fortunately, they all use the finished product lines, which saves the time of making their own lines and ensures the quality of the lines. But there are 40 network lines and 10 optical fibers in total,
