Stagger the company's project peak. I have preliminary plans for several project stages and human resources in mind, and I am ready to sort them out on paper and apply for support from the company leaders. According to the preliminary preparation, the project required by the bidding is completed at the end of July and launched at the end of August. It is very reasonable for the customer to ask for an office on site because of the chaotic accounts and complicated business of the charging system he learned earlier. Therefore, one goal is to build a Datong office and conduct in-depth research on customer needs. Several things can be done now: 1. Determine project members; 2. Establishment of office; 3. Organize the kick-off meeting. Several important project roles have been identified within the company.

Fujian wisdom Tap water 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.

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.

Then on April 23, the bank collection kick-off meeting hosted by us, organized by Datong Thermopower, 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 test The performance test work of Datong Thermal is indispensable. In the past, we

Sometimes a problem occurs in the system and needs to be handled by the original software company. The engineer does not fix the problem but directly changes the value in the background. This is to treat the symptoms rather than the root cause. As a result, many data areas and receivables are not in line with each other, and the current year is not in line with previous years. We joke that the system has been damaged by you. The data migration went on continuously. This huge project lasted more than four months. We were like a cruise in the ocean of data. From time to time, we salvaged some problem data for the business department to verify and modify. Later, we checked the new account and the old account and found that there was a difference of more than 1 yuan. I still remember Director Zhang jokingly said: "This is more than 1 yuan, I will take it!"! In fact, it is in the scope of data migration.
