Docking disturbance

Tax control docking

In the past two years, as the country has vigorously promoted enterprises to issue electronic invoices, Datong Thermo 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. Later, I encountered a lot of problems in the debugging phase. First, the aerospace technology always said that it was too busy to have time. If there was a problem, let us look at the documentation. After several communications, I was also a bit worried. If the documentation can solve the problem, why would 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.

Bank docking

On April 23, the bank collection kick-off meeting hosted by us, organized by the Datong Heating Party, was held in the conference room on the fourth floor. The participating banks were Bank of China, China Construction Bank and Datong Bank. At the meeting, I introduced the docking method and schedule of our project, mainly to promote the bank to start the work as soon as possible and complete the docking and online of agency fees as soon as possible.

At the meeting, all the banks expressed their willingness to actively cooperate with this part of the work, but the schedule was a little tight, after all, the process of the bank was slow. In fact, they later confirmed their words with their actions, because none of them went online within the expected time, which should be regarded as Datong Bank, which completed the online before the official charge.

In the process of bank docking, due to the tight time in the later period, we often worked overtime. From network debugging to service deployment, we got a bank in two days on average. During the technical joint debugging, we Zhang Gong responded one-on-one. Before the online test, we made a detailed test case based on the classification of Datong thermal business types, with a total of 41 types and more than 120 variable parameters. This case provides an important technical guarantee for the stable operation of bank collection in the future.

performance testing

The performance test of Datong Thermal Power is indispensable. We have never made such a big fight on other projects in the past, 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. He wanted to bring the training forward. He was worried that everyone would accept it slowly, so he set aside more time for simulation exercises. Since leaders attach importance to training, we will certainly cooperate with him. I said that the training can be carried out at any time.

On August 5, according to the requirements of Director Xu, I drew up a training schedule: the training of the charging system was divided into two batches, one for the business personnel of the customer service center and the business hall, and the other for the branch companies. One batch of training is divided into 8 sessions, one session every half day, with 105 participants, mainly explaining 9 functions and 59 functional modules of the system; There are four training sessions in the second batch, which are also held every half day. The total number of participants is 56, mainly explaining 32 functional modules of the nine major functions of the system. The training of the customer service system is also the same. In general, the training intensity is quite high, especially for our engineers.

On August 10, the training was in full swing. Our chief engineer had to take a break because of his sore throat. It turned out that not all challenges were so easy to succeed. After all, we were human beings. Without any loudspeakers on the scene, could we speak to so many people every day without interruption without pain? But the training could not be stopped, so I took the place of two trainings, which was also something 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!

Go live

A few days before the project was launched, it was like darkness before dawn. At this stage, the system has been developed as a whole, but due to time constraints and insufficient testing intensity of some new functions, the system is always exposed
