Information processing apparatus including an execution control unit, information processing system having the same, and stop method using the same

An information processing system including one or more information processing apparatus, the information processing system comprising:

• a memory configured to store a program;
• and
• a processor configured to execute the program that causes the information processing system perform functions as:
• a first preservation unit configured to preserve execution request information for information processing;
• an execution unit configured to execute one or more types of the information processing;
• an execution control unit configured to have the execution unit being capable of executing one of the types of the information processing execute the information processing of the execution request information preserved by the first preservation unit;
• and
• a second preservation unit configured to preserve a stop command of the execution unit;
• wherein, if the execution unit does not execute the information processing, the execution control unit checks the second preservation unit at predetermined intervals if the second preservation unit preserves the stop command to have the execution unit execute a stop procedure, and if the execution unit executes the information processing, the execution control unit checks the second preservation unit after the information processing has been completed,
• wherein the execution unit is configured to stop the execution unit according to the stop command and subsequently delete a file indicating the stop command of the execution unit from a predetermined file storage location provided in a worker server;
• wherein the worker server is external to the information processing apparatus, and
• wherein the worker server notifies a user of the information processing apparatus that creates the stop command in the second preservation unit of a stop of the execution unit after the file is deleted.

A stop method executed by an information processing system including a memory configured to store a program, a processor configured to execute the program that causes the information processing system perform the method and one or more information processing apparatus, the method comprising:

• preserving execution request information for information processing;
• executing one or more types of the information processing;
• controlling to have the executing being capable of executing one of the types of the information processing execute the information processing of the execution request information preserved by the preserving;
• and
• preserving a stop command of the executing;
• wherein, if the executing does not execute the information processing, the controlling checks the preserving of the stop command at predetermined intervals if the preserving of the stop command has been done to have the executing execute a stop procedure,
• and if the executing executes the information processing, the controlling checks the preserving of the stop command after the information processing has been completed,
• wherein the executing stops the executing according to the stop command and subsequently deletes a file indicating the stop command from a predetermined file storage location provided in a worker server;
• wherein the worker server is external to the information processing apparatus, and
• wherein the worker server notifies a user of the information processing apparatus that creates the stop command of a stop of the executing after the file is deleted.
