The invention is suitable for the technical field of program updating, and provides a dynamic link library updating method and a server. The method comprises the steps of uploading a first dynamic link library in a running process of a service program, wherein the first dynamic link library is a new dynamic link library; after an application executes a current task, loading the first dynamic linklibrary, removing a handle of a second dynamic link library from a linear list of a memory map, and updating a handle of the first dynamic link library to the linear list of the memory map, wherein the second dynamic link library is an existing dynamic link library; and when the task is executed again, judging whether the update succeeds or not according to an executive result. Through the method,the problem that the service program must be stopped during software update can be effectively solved; all bad influences caused by service stop are eliminated; the software availability is improved;the operation and maintenance cost of a system is reduced; and therefore, the method has relatively high practicality and usability.
Description
technical field [0001] The invention belongs to the technical field of program updating, and in particular relates to a method for updating a dynamic link library and a server. Background technique [0002] At present, computer technology has been integrated into every aspect of people's life. In the financial industry, people handle various deposit and withdrawal services through computers; in the communication industry, people communicate with each other through computers. Computer operating systems serve as a bridge between computers and people. In enterprise applications, Linux, AIX and other UNIX-like operating systems are mainly used based on the consideration of performance, security and usability. [0003] Various types of services are provided by deploying various application software on the operating system. The richer the services provided, the more complex the corresponding software, and the larger the storage space it occupies. The storage space of a large ap...
