PROBLEM TO BE SOLVED: To provide a method and a device for surely reporting the failure of a process interactive with a fault process to the interactive process. ;SOLUTION: Respective process have related characteristic process identifiers and a similarity list containing one or plural entries respectively, containing the identifiers of processes for reporting the failure of any process can be provided through arbitrary selection. A process B 216 calls a similarity service 221 of the kernel of an operating system and by adding or deleting any operation or designating the identifier of a target process, the identifier of a process to report and event type to be generated toward the process to report, the similarity list of the target process is updated. If the process fails, the process end service of an OS kernel investigates the similarity list of the fault processes, the designated event is generated toward the process designated to report concerning respective entries on the list.;COPYRIGHT: (C)1999,JPO
