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 first problem is that the aerospace technology always says that it is too busy to have time. In case of problems, let us look at the documentation. After several communications, I am also worried. If the documentation can solve the problem, why do I look for you? However, Yang Gong, the engineer on the site of TravelSky, helped coordinate later, which helped to adjust the invoicing interface. Then there were various problems during the debugging process, such as the tax-free words could not come out, the invoice download did not return information, etc. These problems occurred every day, and we were also busy working overtime. From the completion of the interface development on July 27 to the completion of the commissioning on August 17, we tested hundreds of invoices, kept trying and making mistakes, and constantly revised them. Fortunately, there were many invoices of Datong Thermal Power, so the cancellation of invoices was not a big deal. We also want to ensure that the electronic ticket will not make mistakes after the project goes online, otherwise Datong Heat will issue thousands or even tens of thousands of tickets every day, and it will be difficult to remedy any mistakes.

Liaoning wisdom Property charging software Considering both speed and security, the platform has made a set of deployment plans. The environment is deployed in the way of VMware virtualization. Five servers form a virtualized private cloud platform, allowing any two servers to fail without affecting the use of the system. Each server is equipped with six 1.2T enterprise hard disks, five of which are interconnected with other servers through 10GbE optical fibers to form a disk storage pool, In addition, two 400G high-speed solid state disks are equipped as cache disks to improve data reading and writing efficiency. For software deployment, we use the tomcat cluster and load balancing deployment mode. Whether it is a toll system or a customer service system, Apache is used as the cluster manager for each service, and multiple Tomcat servers are built under it. This can ensure the stability and security of the system operation, and can also be switched without feeling when the system is updated and upgraded. By the middle of June, we had built 8 virtual servers and 100 virtual desktops on the virtual machine. Four of the eight virtual servers are bank front-end computers, and the other four are application servers, which are respectively the application server of the charging system, the application server of the customer service system, the database server, and a standby server. The next step is to install the virtual desktop. We spent some energy on this link. Yes, yes, it's physical strength! Datong Heating has 4 business halls and 10 branches.

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.
