System and Method for Process Recovery in Multiprocess Operating System

摘要

PURPOSE: A system and a method for recovering a process on a multi-process OS(Operating System) are provided to fast recover a trouble by constructing and managing the information related to all processes on the multi-process OS, and to debug the trouble easily through the trouble occurring particulars. CONSTITUTION: A database(12) stores the generation information and the state information for each process dynamically generated and deleted on the multi-process OS. Management processes(11-1¯11-n) manage respective processes by using the information stored in the database(12), and recover the trouble by deleting and regenerating the corresponding process when the trouble is occurred on a specific process. The database(12) is configured by tree structure nodes matched with each process. A tree structure node includes the process generation information such as a process ID, a process priority, and a process name, and the process management information such as a recover flag, a no-signal flag, and a transmission signal number.
