This is what I expected. On August 16, the training finally came to an end. These days, the brothers and sisters of Datong have listened attentively and enthusiastically. I think an enterprise is a dynamic enterprise if its employees have a positive attitude towards work and are willing to accept new things. We are willing to serve them. Although it has been a little hard these days, we are very pleased. In the following days, Director Xu allowed everyone to get familiar with the system and perform simulation exercises. At the same time, we also printed the User Manual for distribution to help everyone learn and consolidate the system operation. By the time the system went online, everyone's understanding and operating proficiency of the system had reached the standard, and some people even exceeded my expectations. It was great! The first few days before the project was launched, it was like darkness before dawn.

It is hard to avoid errors. Besides, it is not easy to check the amount of more than one billion yuan to the difference of one yuan! I only remember that we were very happy and even excited that day. The hardware part of the hardware entry into Datong is also a highlight. The entire platform involves many hardware and is deployed in the way of VMware virtualization, including servers, firewalls, switching equipment, office computers, high tempo meters, printers, all-in-one computers, televisions, etc. One of the core switches is worth 200000 yuan, which really refreshes my three perspectives. On May 18, the core server hardware arrived.

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.

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,

Zheng Xiong Easy to charge Property charging software Plus the connection with the switching equipment, it is not a simple thing to walk in the cabinet orderly and comfortably. We have been doing it for nearly a day, but we have not been able to complete it. I continued to work in the next day. With the deployment of VMware virtualization, I had a total of 10 days. Looking at the neat computer rooms and fast running servers, I still felt a sense of achievement. So far, 400 mobile phones have not arrived in the hardware part. I think I will take a picture after the goods are delivered. It is also spectacular to have 400 mobile phones on the table and install the paid mobile app at the same time! After the installation and deployment of hardware, the next step is the installation and deployment of software. On May 24, I informed our implementation engineers to start the system deployment. Although some virtualization work has not been completed yet, I decided to proceed in parallel, because functional testing, performance testing, system tuning and other work can only be carried out after the software deployment is completed. We have also spent a lot of time on the system deployment of Datong Thermal Power

In the southeast, northwest and northwest, four business halls are under the management of the head office, which are Xicheng, Nancheng, Beicheng and Huadu business halls. Each business hall has 6-8 toll computers, and each computer needs to install a virtual desktop to log in to the system. In addition, the operating system needs to be redone for computers that cannot be installed. In addition, each branch company needs to have 1-2 computers to use the system, the computer department, the financial department, etc., so we need to install about 80 remote desktops. At that time, there were only 3 people on the site, which was the biggest when we thought about it. Fortunately, the brothers at the information office of Datong Heat helped us a lot, and Director Xu arranged vehicles for us, so that we would not be exhausted in the battlefield. In the past two years, due to the strong promotion of enterprises to issue electronic invoices by the state, Datong Thermal Power has also fully switched from paper invoices to electronic invoices this year. From the perspective of environmental protection, it is beneficial to the country, the people and the environment. However, since it was the first year of use, we also suffered from a lot of pressure. Later, the facts also proved that my concern was not superfluous. The technology docking with us is one of the two major domestic tax control system providers: Aerospace Information Co., Ltd. In April, we got the interface document of TravelSky, but the development of the interface can only be carried out after the overall architecture of the charging system is set up, so the tax control interface will be completed by the end of July.
