The version determination function unit 11 determines whether it is necessary to acquire a patch program based on the comparison result.

  The patch search function unit 13 searches for whether or not the version of the patch program determined to be necessary exists in the program storage device 20. The patch acquisition function unit 12 acquires from the program storage device 20 a version of the patch program determined to be required.

<Details of processing>
Below, the detail of the process of the information processing system 1 which concerns on this embodiment is demonstrated.

<< Acquisition of patch file >>
FIG. 4 is an explanatory diagram of an example of processing for acquiring a patch file. FIG. 4 shows three information processing apparatuses 10 </ b> A to 10 </ b> C and one program storage apparatus 20. The information processing apparatuses 10A to 10C in FIG. 4 have different system versions.

  The information processing apparatus 10A has a system version “1.0”. The information processing apparatus 10B has a system version “1.1”. The information processing apparatus 10C has a system version “1.2”. Further, the program storage device 20 has “V1.4” as the latest patch version. The program storage device 20 includes a patch file (V1.4) of the latest patch version “V1.4”, a patch file (V1.3) of the patch version “V1.3”, and a patch file (V1) of the patch version “V1.2”. .2) and a patch file (V1.1) of the patch version “V1.1” are stored.

  For example, the patch file (V1.4) shown in FIG. 4 is an applicable version “1.3”. The patch file (V1.3) is the applicable version “1.1”. The patch file (V1.2) is the applicable version “1.1”. The patch file (V1.1) is the applicable version “1.0”.

  For example, since the information processing apparatus 10A has the system version “1.0”, even if only the patch file (V1.4) is acquired, it cannot be upgraded to the latest version. Therefore, the information processing apparatus 10A in FIG. 4 upgrades the version “V1.1”, “V1.3”, and “V1.4” to the latest version “1.4” from the version “1.0”. A file is acquired from the program storage device 20. The information processing apparatus 10 </ b> A can be upgraded to the latest version by updating the installed software with patch files of the versions “V1.1”, “V1.3”, and “V1.4”.

  For example, since the information processing apparatus 10B has the system version “1.1”, even if only the patch file (V1.4) is acquired, it cannot be upgraded to the latest version. Therefore, the information processing apparatus 10B of FIG. 4 upgrades the patch files of the versions “V1.3” and “V1.4” from the version “1.1” to the latest version “1.4”. Get from 20. The information processing apparatus 10 </ b> B can be upgraded to the latest version by updating the installed software with patch files of the versions “V1.3” and “V1.4”.

  For example, since the information processing apparatus 10C has the system version “1.2”, even if only the patch file (V1.4) is acquired, it cannot be upgraded to the latest version. Therefore, the information processing apparatus 10C in FIG. 4 upgrades the version “1.2” to the latest version “1.4”, so that the patch storage files of the versions “V1.3” and “V1.4” Get from 20. The information processing apparatus 10 </ b> C can be upgraded to the latest version by updating the installed software with patch files of the versions “V1.3” and “V1.4”.

  As described above, FIG. 4 illustrates an example of a patch file acquired when the information processing apparatuses 10A to 10C having different versions of installed software are upgraded to the latest version. The information processing apparatuses 10B and 10C in FIG. 4 have different software versions, but the patch files necessary for upgrading to the latest version are the same.

  FIG. 5 is a flowchart of an example of processing of the information processing apparatus 10 that acquires a patch program. In step S <b> 1, the version acquisition function unit 14 of the information processing apparatus 10 acquires the latest patch version from the program storage device 20. In the program storage device 20, the list of the latest patch versions is arranged. The version acquisition function unit 14 sets the acquired latest patch version as version X.

  In step S2, the version determination function unit 11 of the information processing apparatus 10 determines whether the version X is newer than the system version (client version).

  If the version X is newer than the client version, the patch acquisition function unit 12 of the information processing apparatus 10 acquires the version X patch program from the program storage device 20 in step S3.

  In step S4, the version acquisition function unit 14 acquires an applicable version of the version X patch program. The version acquisition function unit 14 sets the applicable version of the acquired version X batch program to version X, and then returns to the process of step S2.

  In step S2, if the version X is not newer than the client version, the patch acquisition function unit 12 of the information processing apparatus 10 determines that acquisition of the patch file necessary for upgrading to the latest version has been completed, The process of the flowchart of FIG.

  For example, in the example of the information processing apparatus 10A in FIG. 4, the latest patch file (V1.4) is acquired by the processing of the first steps S1 to S4. In the second process of steps S2 to S4, a patch file (V1.3) is acquired. In the third process of steps S2 to S4, a patch file (V1.1) is acquired.

  In the information processing system 1 according to the present embodiment, the information processing apparatus 10 may periodically check the program storage apparatus 20 for updates of the patch file, or the program storage apparatus 20 may transfer the patch file to the information processing apparatus 10. It is also possible to notify the update.
