Title: Dynamic replacing device for component and computer- readable storage medium
Inventor: KAMIKUBO SHINAKO
IPC: G06F9/46
Filed: 2000-04-05
Abstract: PROBLEM TO BE SOLVED: To replace a component, without having to stop a job in a multiprocess/multi-thread configuration system. SOLUTION: A message queue control mechanism 120 receives a dynamic replacement request through a communication control mechanism 110 and issues that request to all component managing mechanisms 132 operated in respective threads 131 of an application process 130. As soon as all threads are turned into standby state, each of component managing mechanisms 132 unloads a component 134 and performs replacing processing into a new component 160. After the end of replacing processing, the threads are restarted. When there is a request before a replacing instruction, that request is first executed while waiting a request from a user 170 during replacement, but when the request is after the replacing instruction, it is held and after the threads are restarted, the job is performed by the new component 160.  Thus, the component can be replaced, without having to stop a system under operating and without making the user conscious thereof.
