  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of an information processing apparatus. The information processing apparatus 10 includes an extraction unit 11, a display control unit 12, and a storage unit 13, and corresponds to, for example, an application server of application middleware for a business system.

  The extraction unit 11 extracts an environment setting item whose parameter value has been changed within a specified period from the entire environment setting item. The display control means 12 generates and displays a change history screen including the extracted environment setting items and changed parameter values. The storage unit 13 stores various information such as environment setting item names, default values as parameter values, values after change, date and time of change, and the like.

  In the example illustrated in FIG. 1, the information processing apparatus 10 has environment setting items # 1 to #n. Note that the parameter values of the environment setting items # 1 to #n can be arbitrarily changed by a user operation within the setting range.

  Here, it is assumed that the user has designated this period for the information processing apparatus 10 to confirm the change history of the environment setting items for three days from August 9, 2012 to August 11, 2012. .

  Further, it is assumed that the parameter value of environment setting item # 1 is changed to 10 and the parameter value of environment setting item # 2 is changed to 120 on August 9, 2012. Further, on August 10, 2012, the parameter value of environment setting item # 2 is changed to 125, the parameter value of environment setting item # 4 is changed to 60, and the parameter value of environment setting item # 5 is changed to 70. . Further, it is assumed that the parameter value of environment setting item # 6 is changed to 80 on August 11, 2012.

  In such a state, the extraction unit 11 extracts the environment setting items whose parameter values have been changed within the specified period from August 9 to August 11, 2012, from the environment setting items # 1 to #n. To do. Then, the display control unit 12 generates and displays the change history screens 12-1 to 12-3 including the extracted environment setting items and the changed parameter values.

  The change history screen 12-1 shows information in which the parameter value of the environment setting is changed on August 9, 2012. That is, on the change history screen 12-1, change history information is displayed in which the parameter value of the environment setting item # 1 is 10 and the parameter value of the environment setting item # 2 is 120.

  The change history screen 12-2 shows information in which the parameter value of the environment setting has been changed on August 10, 2012. That is, on the change history screen 12-2, change history information is displayed in which the parameter value of environment setting item # 2 is 125, the parameter value of environment setting item # 4 is 60, and the parameter value of environment setting item # 5 is 70. The

  Further, the change history screen 12-3 shows information in which the parameter value of the environment setting is changed on August 11, 2012. That is, the change history information that the parameter value of the environment setting item # 6 is 80 is displayed on the change history screen 12-3.

  In this manner, the information processing apparatus 10 generates a change history screen including the environment setting item whose parameter value has been changed within the specified period and the changed parameter value from among the entire environment setting items. List. As a result, the user can easily check the change history of the environment setting item.

  Next, the data structure related to the screen display of the environment setting items will be described. FIG. 2 is a diagram illustrating an example of a data structure related to the screen display of environment setting items. The data structure related to the screen display of the environment setting items has attributes of “tree configuration”, “number of screens”, “number of changeable screens”, and “number of items”.

  “Tree configuration” is information indicating the name of the environment setting item and the subordinate relationship (tree) of the related environment setting items. “Number of screens” is information indicating the number of screens required to display the environment setting items. “Number of changeable screens” is information indicating the number of screens whose environment setting items can be changed. “Number of items” is information indicating the number of environment setting items.

  In the application server of this example, the total number of screens related to the environment setting is 59 or more, of which the number of screens that can be changed is 30 or more, and the number of items is 440 or more. When operating a system, an operating environment is usually created by repeating settings, trials, and adjustments in a certain range of items.

  Here, the problem of the current environment setting screen will be described. As shown in FIG. 2, there are a wide variety of environment setting items (screens). For this reason, when the user wants to change the setting, the user has to perform the setting work while switching the screen many times, resulting in a reduction in work efficiency. In addition, even if it is possible to navigate between screens using a tree operation, there is a problem that it is not easy to know the change history such as what item is on which screen, the past, and where it is fixed.

  The information processing apparatus 10, the screen display method, and the screen display program according to the present technology have been made in view of such points, and can easily check the change history of the environment setting items, and can further perform environment setting work. The screen is displayed in order to improve convenience.

For ease of illustration, the screen 20 is divided into two drawings, but the screen 20 can actually display a list on a single screen. In addition, other function buttons may be displayed.

  The display period setting field 21 is a field for setting the date when the user wants to see the change history. When a period is set in the display period setting field 21, a change history screen in which the parameter value of the environment setting item has been changed within the specified period is displayed.

  The change history screens 22-1 to 22-4 are screens that display a change history indicating which environment setting items have been changed. For example, a change history screen generated within the period set in the display period setting field 21 is, for example, It is displayed by sorting by year, month and day.

  The change history screens 22-1 to 22-4 display parameter values actually changed in the past, item names of the parameter values, and the date and time when the change is confirmed. The change history screens 22-1 to 22-4 are screens for displaying only the change history (parameter value changing operation is performed via the setting change screen 23). Further, radio buttons described later are displayed on the left end of the change history screens 22-1 to 22-4.

  The setting change screen 23 is a screen displayed when the user wants to change the parameter value of the environment setting item. The user can change the parameter value of a desired environment setting item via the setting change screen 23. The apply button 24 is a button that the user presses when the parameter value changed through the setting change screen 23 is confirmed.

Thereby, the user can confirm the parameter value changed by a series of operations on one screen.

  Further, it is possible to easily change the parameter value within a predetermined date through the setting change screen. Furthermore, since the change history can be grasped on one screen, for example, it becomes easy to collate with an error occurrence log or the like, and it is possible to efficiently perform troubleshooting.

  Next, a table managed by the storage unit 13 of the information processing apparatus 10 will be described. The storage unit 13 holds and manages a change history table T1, a change table T2, and a default value table T3.

  FIG. 10 is a diagram illustrating a configuration example of the change history table. The change history table T1 is a table for managing the change history for each changed year, month, day, leaving all the changed parameter values, and holds all past change histories.

  The change history table T1 has an attribute of “change date / time”, and “change date / time” includes attributes of “item name” and “value”. “Change date / time” is information indicating the date / time when the parameter value of the environment setting item is changed. The “item name” is information indicating the name of the environment setting item whose parameter value has been changed. “Value” is information indicating the parameter value after the change.

  FIG. 11 is a diagram illustrating a configuration example of the change table. The change table T2 is a table for managing all the latest environment setting items and parameter values changed within the period set in the display period setting field 21.

  Similar to the change history table T1, the change table T2 has a “change date / time” attribute, and the “change date / time” includes attributes of “item name” and “value”. The change table T2 manages information displayed on the setting change screen, so that “item names” do not overlap.

  FIG. 12 is a diagram illustrating a configuration example of a default value table. Depending on the selection status of the change date (change history screen selection status), the default value set in the environment setting item at the beginning of system operation may be displayed.

  Therefore, in preparation for such a case, a default value table T3 is generated and the default values for all the environment setting items are managed. The default value table T3 includes attributes of “item name” and “default value”.

  Next, a memory group managed by the storage unit 13 of the information processing apparatus 10 will be described. FIG. 13 is a diagram illustrating a configuration example of a memory group. The memory group 13a mainly has a work area, a change period list, and a data update flag.

  The work area further includes a changed work, a changed work sub, and a history work. The changed work is a display work including all the changed contents changed within the display period. The change work sub is a change work including all the changed contents changed within the display period.

  The history work is a work that holds the change contents of the selected change date. The change period list is a list for sorting the change date. The data update flag is a flag for determining whether or not the contents of the changed work sub are changed.

Next, the screen display operation will be described using a flowchart. FIG. 14 is a flowchart showing the display operation of the changed parameter value.
[S1] The user presses the apply button 24.

  [S2] The display control means 12 writes the parameter value changed on the screen in the change history table T1. For example, assume that the parameter value of the WU001: application maximum processing time related to work unit setting is changed to 500 at 2012/11/8 15:52:30.

  In this case, 2012/11/8 15:52:30 is written in the “change date / time” of the change history table T1, and the “item name” included in the “change date / time” is “WU001: work unit setting”. Application maximum processing time "is written. Furthermore, 500 is written in the “value” column corresponding to the item name.

  [S3] The display control means 12 adds the “change date / time” data written in step S2 to the change table T2. That is, 2012/11/8 15:52:30 is added to the “change date” in the change table T2.

[S4] The display control means 12 searches the change table T2 with the data of “item name”.
[S5] The display control means 12 determines whether there is a matching “item name” in the change table T2. If there is a matching “item name” in the change table T2, go to step S6, otherwise go to step S7.

[S6] The display control means 12 deletes the “item name” data and the “value” data from the change table T2 in order to retain the latest data.
For example, it is assumed that “item name” data is written as “WU001: application maximum processing time for work unit setting” and “value” data as 300 in the change table T2.

  In this case, since “WU001: application maximum processing time related to work unit setting” of the same “item name” changed in step S2 exists, “WU001: application maximum processing time related to work unit setting” and “item name” The “value” of 300 is deleted.

  [S7] The display control means 12 writes “item name” data and “value” data in association with “change date / time” in the change table T2. That is, in this example, “WU001: Application maximum processing time related to work unit setting” is written in “Item name” of “Change date / time” = 2012/11/8 15:52:30 in the change table T2. It is. Furthermore, 500 is written in the “value” corresponding to the “item name”.

  [S8] The display control means 12 determines whether there is a next “item name” to be searched. If there is a next "item name", the process returns to step S4 to repeat the process of updating the change table T2, and if there is no next "item name", the process goes to step S9.

[S9] The display control means 12 copies the data in the change table T2 to the changed work.
[S10] The display control means 12 outputs and displays the changed work data on the screen.
15 and 16 are flowcharts showing the display operation of the setting change screen.

  [S21] When the user wants to display a setting change screen, the user presses a radio button for a desired year / month / date / time. That is, the user selects one change history screen from a plurality of change history screens displayed on the screen, and presses a radio button provided on the selected change history screen.

[S22] The display control means 12 initializes the history work.
[S23] The display control means 12 recognizes the year / month / day instructed in step S21, reads the data of the recognized “change year / month / day” from the change history table T1, and sets it as the history work.

[S24] The display control means 12 copies the value of the changed work to the changed work sub.
[S25] The display control means 12 compares the “item name” of the history work with the “item name” of the changed work sub.

[S26] If the "item name" matches, go to step S27, otherwise go to step S28.
[S27] The display control means 12 overwrites the “value” of the “item name” of the changed work sub with the “value” of the “item name” of the history work. Go to step S42.

[S28] The display control means 12 searches the change history table T1 by “item name”.
[S29] If the "item name" matches, go to step S30, otherwise go to step S31.

[S30] The display control means 12 adds the associated “change date / time” to the change period list.
[S31] The display control means 12 determines whether or not there is the next “change date / time”. If there is a next “change date / time”, the process returns to step S28, and if not, the process goes to step S32.

[S32] The display control means 12 sorts the change period list in the order of year, month, day, and time (descending order).
[S33] The display control means 12 compares the “change date / time” of the change work sub with the “change date / time” of the change period list.

  [S34] If the “change date / time” in the change period list is newer than the “change date / time” in the change work sub, the display control means 12 goes to step S35. If “change date / time” of the change period list is older than “change date / time” of the change work sub, the process goes to step S37.

[S35] The display control means 12 overwrites the "value" of the "item name" of the changed work sub with the "value" of the "item name" associated with the "change date / time" of the change period list.
[S36] The display control means 12 sets the data update flag to “true”.

  [S37] The display control means 12 determines whether or not there is a “change date / time” next to the change period list. If there is a next “change date,” the process returns to step S33, and if not, the process goes to step S38.

  [S38] The display control means 12 determines whether or not the data update flag is set to “true”. If not set, go to step S39, and if “true”, go to step S40.

[S39] The display control means 12 overwrites the “value” of the “item name” of the changed work sub with the “default value” of the corresponding “item name” in the default value table T3.
[S40] The display control means 12 sets “false” in the data update flag.

[S41] The display control means 12 initializes the change period list.
[S42] The display control means 12 determines whether or not there is the next “item name” in the history work. If there is a next “item name”, the process returns to step S25, and if not, the process goes to step S43.

[S43] The display control means 12 outputs and displays the changed work sub data on the screen.
Next, a case where display control of the present technology is realized by a computer will be described. The processing functions shown above can be realized by a computer. FIG. 17 is a diagram illustrating a configuration example of computer hardware used in the present embodiment. The entire computer 100 in the information processing apparatus 10 is controlled by a CPU (Central Processing Unit) 101. A RAM (Random Access Memory) 102 and a plurality of peripheral devices are connected to the CPU 101 via a bus 108.

  The RAM 102 is used as a main storage device of the computer 100. The RAM 102 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the CPU 101. The RAM 102 stores various data necessary for processing by the CPU 101.

  Peripheral devices connected to the bus 108 include an HDD (Hard Disk Drive) 103, a graphic processing device 104, an input interface 105, an optical drive device 106, and a communication interface 107.

  The HDD 103 magnetically writes and reads data to and from the built-in disk. The HDD 103 is used as a secondary storage device of the computer 100. The HDD 103 stores an OS program, application programs, and various data. Note that a semiconductor storage device such as a flash memory can also be used as the secondary storage device.

  A monitor 104 a is connected to the graphic processing device 104. The graphic processing device 104 displays an image on the screen of the monitor 104a in accordance with a command from the CPU 101. Examples of the monitor 104a include a display device using a CRT (Cathode Ray Tube) and a liquid crystal display device.

  A keyboard 105 a and a mouse 105 b are connected to the input interface 105. The input interface 105 transmits signals sent from the keyboard 105a and the mouse 105b to the CPU 101. Note that the mouse 105b is an example of a pointing device, and other pointing devices can also be used. Examples of other pointing devices include a touch panel, a tablet, a touch pad, and a trackball.

  The optical drive device 106 reads data recorded on the optical disc 106a using laser light or the like. The optical disk 106a is a portable recording medium on which data is recorded so that it can be read by reflection of light. Examples of the optical disc 106a include a DVD (Digital Versatile Disc), a DVD-RAM, a CD-ROM (Compact Disc Read Only Memory), and a CD-R (Recordable) / RW (Rewritable).

  The communication interface 107 is connected to the network 110. The communication interface 107 transmits and receives data to and from other computers or communication devices via the network 110.

  With the hardware configuration as described above, the processing functions of the present embodiment can be realized. Further, when the processing function of the present embodiment is realized by a computer, a program describing the processing content of the function of the information processing apparatus 10 is provided.

  By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic storage device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic storage device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Optical discs include DVD, DVD-RAM, CD-ROM / RW, and the like. Magneto-optical recording media include MO (Magneto Optical disk). The recording medium for recording the program does not include a temporary propagation signal itself.

  When distributing the program, for example, a portable recording medium such as a DVD or a CD-ROM in which the program is recorded is sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. Further, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.

  In addition, at least a part of the above processing functions can be realized by an electronic circuit such as a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or a PLD (Programmable Logic Device).

  As mentioned above, although embodiment was illustrated, the structure of each part shown by embodiment can be substituted by the other thing which has the same function. Moreover, other arbitrary structures and processes may be added.
