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

Jinsha Easy to charge Heating charge system software 698 chimneys were pulled out, making outstanding contributions to the realization of "Datong Blue". Recall that former sales colleagues also shared the information experience of Datong Thermal, as well as the whole process related to this bidding. Datong Heating has established an information management platform at an early stage in cooperation with a company in Beijing in charging and customer service software systems, and has a deep understanding of information management. However, with the change of heating policy and the innovation of information technology, the original management system has been unable to meet the growing management needs of thermal enterprises. In addition, the original system has not been upgraded for many years, the system is severely stuck, and the statistical report is inaccurate, which has greatly increased the workload of managers. In particular, the service provided by the original heating software supplier was not up to standard.

The year was the year when the global return on assets was poor since records began. Most fund managers were proud to lose less than 5% in this year; Some people say that China's economic L has not reached the end, and no one knows how long the horizontal line will be after reaching the end; In the past few months, the President and Prime Minister of the People's Republic of China also rarely expressed on official occasions the economic downturn and the situation was stormy; The Sino US trade war continued to ferment. In fact, the common people's cognition often lags behind the environment. It can be said that the country has started macro-control as far back as 2015. At that time, a small number of industries began to feel the chill first. I remember that when companies recruited in those years, many of them jumped from shipbuilding, machinery and other industries to the IT industry. The IT industry in China belongs to the service industry and also has high-tech attributes, so it is less and slower affected by the economic crisis. But under the overall depression, can the IT industry be independent? Since the reform and opening up, especially after China's entry into WTO, foreign capital has brought technology and experience to China at the same time.

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 company will carry out its own work. In addition to managing their own organizational structure, personnel, and processes, subsidiaries also need to establish a number of personalized management models: 1. including their own maintenance of basic information such as residential quarters, heat sources, heat exchange stations, and basic categories; 2. The heating policies in different regions are different, and each subsidiary needs to maintain its own corresponding billing strategy; 3. Each subsidiary can use different methods of issuing bills, including self printed receipt invoices, tax controlled invoices, tax controlled electronic tickets, etc. Each subsidiary of business approval management can independently configure business processes, such as exemption approval, suspension approval, forced suspension approval, area adjustment approval, reheat approval, and network access approval. The process supports hierarchical approval of subsidiaries and groups. Personnel at all levels of statistical analysis can only browse and operate the data range of this level; Group headquarters can view real-time business data and operation data of all subsidiaries in real time for comparison and assessment; Provide rich reports and charts to show the overall operating data of each subsidiary and group.

This is also an important step. As we continue to deepen our data analysis, we find that the data migration work of Datong Thermal is much more complex than we thought. This complexity is not the huge data magnitude mentioned above, but the non-standard data. We learned that some functions of the original charging system in the application process can not meet the business needs, so people who operate the software often use an unconventional operation to achieve a certain business, such as directly modifying the heating fee receivable if the recovery cannot be achieved after the suspension is reported, directly modifying the standing book if the area settlement is not correct, and Director Zhang also said.
