PURPOSE:To efficiently inspect the cause of fault occurrence by providing an identifier(ID) storing table for an executing application program and a fault occurring application program, a fault information storing area, a fault processing program and so on. CONSTITUTION:When a system fault occurs, control is transferred from an application program(AP) 10 to a fault processing program 111 in an execution control program 11 and information relating to the fault is registered from the executing AP 10, a communicating buffer 12, etc., to a fault information storing area 115. Then, the ID of the executing AP 10 already written in an executing AP ID storing table 114 is copied in a fault occurring AP ID storing table 16 and the recovery processing of the fault is executed. At the time of restarting the AP 10 after ending the fault processing, the ID is written in the table 114 and compared with the ID stored in the table 116, and when both the IDs are equal, all the contents of the buffer 12 are copied to the area 115 or the like. When a fault occurs again, the contents of the area 115 are sent to an output device, so that the cause of fault occurrence can be efficiently inspected. |
