PURPOSE:To check easily whether the generation order of processing request events to a data processing system is correct in every space or not, by providing a sequency identifier storage area and a sequence check table. CONSTITUTION:It is assumed that a generated even detecting part 1 detects a generated even aj in a space Si. A current sequence identifier SQ is inputted from an identifier storage area 4 to a sequence identifier comparing part 11, and a sequence identifier where the even aj can be accepted is inputted from a field 7 to the comparing part 11. If they do not coincide with each other, infomation indicating that the event aj cannot be accepted in the space Si is reported to an error processing part 12; and if they coincide with each other, a new sequence identifier SQ is taken out from a field 8 to update the storage area 4, and the generation of the event aj is reported to an execution processing part 13-i for the space Si. Thus, a check part 10 performs the processing on a basis of a table 5 and etc. without paying attention to spaces and generated events individually. |
