PURPOSE: To keep consistency between a data structure and a control structure in a connection facility at the time of the existence of a true or apparent error in a link forming the mutual connection. CONSTITUTION: This data processing system is provided with a command responder 10, a command initiator 11, and a program sequencing means. The command responder 10 includes a program control command execution means, a control storage means including a command state storage area, and a data storage means. The command initiator communicates commands, which request actions to be executed by the command execution means and return of responses generated by these actions, with the command responder and sends a first command to the command responder to identify and reserve a part of the command state storage area. The program sequencing means selectively specifies a part, which is reserved in accordance with a second command from the command initiator 11, to store state information related to the second command. |
