2. Strengthen active maintenance and protection. Because the strategy and practice of passive protection can no longer be used, maintenance personnel are on tenterhooks every day, and users have many opinions. It is necessary to carefully plan, make use of the idle practice of holidays and system applications, actively check and repair the system, eliminate hidden dangers, regularly carry out emergency plans and drills, and allocate accessories to ensure the online stability of the system.
3. Eliminate the single point of equipment failure. The design and implementation of software, hardware and running environment of information system should avoid single point of failure. First of all, the system should adopt a reliable, extensible and technologically advanced architecture and deployment scheme. Secondly, improve, upgrade and expand the system in time, and at the same time, greatly improve and upgrade the operation and safety technical measures of infrastructure such as computer room and network.
4. Provide one-stop service. Not only the operation and maintenance mode should be centralized and unified, but also the service interface should be unified. Set up a unified service telephone and e-mail, equipped with relevant post personnel and processes, implement one-stop service, and track the service process throughout.
5. Visit important users at home. Important and key users of enterprise information systems, such as leaders at all levels and personnel in key business positions, should insist on taking the initiative to come to the door, solve their problems, understand their needs and listen to their opinions.
