Within half a year, farmers can feel the price fluctuation and take measures; The second is industry. Due to the long upstream and downstream chains, the industry has almost been impacted for two years; Once again, it will gradually affect the service industry, because the primary and secondary industries are no longer working, and the skin is not there, and the hair will not be there. The sales of cars and mobile phones that we like to talk about plummeted in 2018, and the Internet and game industries are busy downsizing. Back in 2008, when China was dealing with the financial crisis, it made a big move of 4 trillion yuan (in 2008, M2 was 47.5 trillion yuan, in 2018, M2 reached 182.7 trillion yuan, credit growth was rapid, M2 has exceeded the total of the United States and the European Union). In the past decade, China has been ramping up from top to bottom, especially local governments State owned enterprises are trying to delay the coming depression, and are proud of their debts. In this process, the originally strong private economy could not support it, and the government and state-owned enterprises that could have been deployed lightly put on heavy shackles (liabilities).

And discuss the key issues. In general, Datong thermal customers have a great cooperation, and the communication staff have a strong sense of responsibility and enthusiasm. Everyone adheres to the idea of exposing problems and solving problems as soon as possible, actively promotes the project progress, and does not let problems hide until the project goes online. I also got a lot of user stories from customers, which are very valuable. On April 10, the second week of project implementation, the colleagues in charge of data migration began to be stationed. Datong Thermal's customer base data is about 600000, and the historical data of 7 years constitute a large amount of data since I started the project, so we attach great importance to data. One step of data migration is data analysis.

Jiangsu Easy to charge Natural gas charging software 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.

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.
