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.

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.

The division had arrived two days earlier and waited. In the afternoon, we pulled the hardware into the computer room under the guidance of the Information Department. The machine room of Datong Thermal Power is very professional. The outer room is the monitoring room, the inner room is the hardware equipment, and the middle is a large glass wall. The temperature and moderation of the machine room can be easily seen through the glass. The door of the computer room is identified by fingerprint, and only the personnel of the information department can enter and exit. After entering the computer room, there were 12 cabinets in order, and the wiring was neat and not messy. We put the server on the shelf together with our brother from the Information Department, and then we went on wiring. There are 5 servers in this project, each server has 8 gigabit ports and 2 10 gigabit ports, that is to say, each server needs 8 network cables and 2 optical fibers. Fortunately, they all use the finished product lines, which saves the time of making their own lines and ensures the quality of the lines. But there are 40 network lines and 10 optical fibers in total,

The project kick-off meeting can be arranged tomorrow. The project kick-off meeting must be held with as much publicity as possible. Otherwise, who knows what your project manager is, who knows you and who treats you. Just like the appointment of generals before the ancient war, there must be a ceremony, but the organization, form and appointment of the project kick-off meeting are almost all promoted by the project party. That is to say, we should seize this opportunity to promote ourselves and avoid being passive in the process of future project promotion. Informatization work is inherently difficult. It is very important to use the details of each link to accumulate trust between both sides. With trust, we can face and solve all difficulties together, even if there is no trust

Shenzhen wisdom Natural gas charging software As a professional supplier of heating customer service software, Feiyi Software has developed a group version of heating charge management system for group heating enterprises. The group needs to pay attention to several aspects of management and control: unified planning and coding of user numbers of each subsidiary; Decentralized entry and unified supervision of various charging channels and funds; Decentralized docking and unified supervision of receipts, general tickets and electric tickets in various regions; Unified management of organizational structure and authority roles at all levels, and formulation of work approval process at all levels; Data hierarchical filtering control; Differentiation support of basic data and cost data of heat users; Support for local heating policies, regulations and billing strategies; Multi system docking at all levels; Integration and analysis of the group's big data, and horizontal analysis of all aspects of the data of the subordinate heating companies
