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.

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.

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 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.

Sansui Easy to charge Natural gas charging software The project department immediately received the news of winning the bid. As the project implementation manager of this project, the feeling of joy was fleeting, and the responsibility that followed was heavy. But when I saw that the colleagues in the R&D department were all working hard, with high morale and confidence, I was relieved of most of them. Calm down and check the basic data of Datong Thermal Power. It is learned that the network area of Datong Thermal Power is 72.6 million square meters, which is a national large first-class enterprise, with 10 heating branches, 1 maintenance and repair branch and 5 customer service points. As of 2017, the company has laid a total of 875 kilometers of primary heating pipe network, with a central heating area of 58.6 million square meters for cogeneration. For more than a decade, 897 coal-fired heating boilers have been removed.
