Abstract

A method for controlling an information processing apparatus configured to store a program code including a plurality of program modules and, every time an execution request for the program code is accepted that is transmitted from a user terminal communicatively connected therewith, sequentially execute each program module included in the program code to transmit an execution result for the execution request to the user terminal. The method comprises, when an update request for the program code is received from a management computer communicatively connected therewith, stopping acceptance of a new execution request for the program code transmitted from the user terminal and stopping the execution of the program module being currently executed, transmitting to the user terminal the information indicating that execution of a program module executed in response to the execution request for the program code is terminated, as the execution result for the execution request, based on information for identifying a program module to be updated included in the update request for the program code, updating the program module to be updated, and starting acceptance of an execution request for a new updated program code.

Claims

1. A method for controlling an information processing apparatus configured to store a program code including a plurality of program modules and, every time an execution request for the program code is accepted that is transmitted from a user terminal communicatively connected therewith, sequentially execute each program module included in the program code to transmit an execution result for the execution request to the user terminal, the method comprising:

when an update request for the program code is received from a management computer communicatively connected therewith,

stopping acceptance of a new execution request for the program code transmitted from the user terminal and stopping the execution of the program module being currently executed;

transmitting to the user terminal the information indicating that execution of a program module executed in response to the execution request for the program code is terminated, as the execution result for the execution request;

based on information for identifying a program module to be updated included in the update request for the program code, updating the program module to be updated; and

starting acceptance of an execution request for a new updated program code.

2. The method for controlling an information processing apparatus of claim 1,

wherein the information processing apparatus includes a runtime information storage unit storing setup information for listing conditions when the program code is executed, and

wherein, after the program code is updated to the new program code, the new program code is executed based on the setup information referenced when executing the program code before the update.

3. The method for controlling an information processing apparatus of claim 1,

wherein the management computer includes

an update history information storage unit storing the identification number of the new program code in relation to information for identifying each program module making up the new program code every time the update request for the program code is transmitted to the information processing apparatus;

and

a deployment information storage unit storing information for identifying the each program module stored in the information processing apparatus,

wherein, when transmitting to the information processing apparatus the update request including the information for identifying the program module to be updated, a program module needed to be updated in order to constitute the new program code is identified based on the information for identifying the each program module stored in the deployment information storage unit and based on the information for identifying each program module making up the new program code related with the identification number of the new program code input from a user interface, and wherein the identified program module is identified as the program module to be updated.

4. The method for controlling an information processing apparatus of claim 1,

wherein the information for identifying a program module to be updated included in the update request for the program code is information for identifying a new program module to be added to the program code, and

wherein the information processing apparatus updates the program code to the new program code by storing the new program module transmitted from the management computer.

5. The method for controlling an information processing apparatus of claim 1,

wherein the information for identifying a program module to be updated included in the update request for the program code is information for identifying a program module to be deleted from the program code, and

wherein the information processing apparatus updates the program code to the new program code by clearing the program module to be deleted as stored.

6. The method for controlling an information processing apparatus of claim 1,

wherein the information processing apparatus updates the program code to the new program code by clearing the program module to be updated as stored and by storing the new program module transmitted from the management computer.

7. The method for controlling an information processing apparatus of claim 1,

wherein the program code is a program code written in an object-oriented programming language, and

wherein the each program module is a program code defining a class.

8. An information processing apparatus comprising:

a program code storage unit that stores a program code including a plurality of program modules;

an execution request acceptance unit that accepts an execution request for the program code transmitted from a user terminal communicatively connected therewith;

a program code execution unit that sequentially executes each program module included in the program code every time the execution request for the program code is accepted;

an update request reception unit that receives an update request for the program code from a management computer communicatively connected therewith;

an execution request acceptance cancellation unit that stops acceptance of a new execution request for the program code transmitted from the user terminal;

a program code forced termination unit that terminates execution of a program module being currently executed;

an execution result transmission unit that transmits to the user terminal the information indicating that execution of a program module executed in response to the execution request for the program code is terminated, as an execution result for the execution request;

a program code update unit that updates a program module to be updated included in the update request for the program code, based on information for identifying the program module to be updated; and

an execution request acceptance start unit that starts acceptance of an execution request for a new updated program code.

9. A program operable to cause an information processing apparatus storing a program code including a plurality of program modules to execute the steps of:

accepting an execution request for the program code transmitted from a user terminal communicatively connected therewith;

sequentially executing each program module included in the program code every time the execution request for the program code is accepted;

receiving an update request for the program code from a management computer communicatively connected therewith;

stopping acceptance of a new execution request for the program code transmitted from the user terminal;

terminating execution of a program module being currently executed;

transmitting to the user terminal the information indicating that execution of a program module executed in response to the execution request for the program code is terminated, as an execution result for the execution request;

updating a program module to be updated included in the update request for the program code, based on information for identifying the program module to be updated; and

starting acceptance of an execution request for a new updated program code.
