Description

  The present invention relates to a maintenance support system for preventing erroneous transmission of a maintenance command (command) to a target maintenance target terminal for maintenance of a computer system.

  For maintenance of computer systems, maintenance workers enter maintenance commands (commands) into terminal software installed on maintenance terminals and send them to the computer system (maintenance target device) via the network for services and processing. Request. In addition, a maintenance procedure manual is created in advance by an electronic file by a maintenance worker before maintenance is performed, and the contents and order of input of commands are described so that there is no error in the maintenance procedure.

  Maintenance procedures are closely scrutinized by multiple people. This is because an error of one character can cause a large-scale failure of the maintenance target device. In addition, one command is several characters to several hundred characters, and the procedure manual ends with several command lines if the maintenance is small, but if the maintenance is large, the command is several hundred to several characters. There may be a thousand lines.

  When the maintenance is actually performed, the maintenance worker inputs these commands by copying one line of the command from the maintenance procedure manual and pasting it on the terminal software. In particular, when the maintenance terminal is a CLI (Command Line Interface) and a maintenance mode in which a command based on a list of character strings is input to the terminal software, the maintenance worker inputs an input device such as a keyboard for each character, Manual input to the terminal software not only increases the maintenance time, but also causes erroneous commands such as typographical errors and omissions due to input errors of the maintenance operator, causing failure of the maintenance target device.

  In order to prevent the occurrence of a failure due to a mistake in maintenance work, it is common to use a maintenance work tool to prevent mistakes and improve work efficiency.

JP2009-200808A

  Patent Document 1 is a file update confirmation system that supports confirmation of file update work of an exchange, and includes a maintenance terminal and a simulation device that performs confirmation processing of the file update work. When a command for performing an update is input, it includes command transmission means for transmitting the input command to the simulation device. The simulation device receives a command received from the maintenance terminal in a current procedure during a file update operation. There has been disclosed a file update confirmation system that appropriately prevents an operation error such as erroneous input of a command or missing a procedure by determining whether or not a command to be transmitted is matched.

  In Patent Document 1, when the simulation apparatus determines that the command is correct, the monitoring and control apparatus issues (transmits) an actual command to the exchange based on the command received from the maintenance terminal. However, in Patent Document 1, a maintenance command (command) described in the work procedure manual is registered in the simulation in advance, and input other than the registered maintenance command (command) becomes impossible. If there is any unexpected situation, it is impossible to execute an important command that is urgently needed, and again to input the necessary command to deal with the unexpected situation. In addition, an operation to be input as an executable command to the simulation apparatus is additionally generated. Further, when an incorrect command passes through the simulation apparatus, the incorrect command directly issues (transmits) an actual command to the exchange, which may cause a failure.

  The object of the present invention is to input the contents written in the procedure manual by deleting the execution instruction (line feed code) from the command so that it is not added when the command is entered by copying / pasting the contents described in the procedure manual. Without executing commands immediately, even if a wrong command is entered, it can be prevented immediately, and the final confirmation and correction of the command can be performed to prevent erroneous command execution on the maintenance target device. It is to provide a system, a method, and a program.

  According to the maintenance support system of the present invention, in the maintenance support system that supports the maintenance of the maintenance target terminal, the execution instruction deleting means that deletes the execution instruction from the command acquired from the procedure manual and imports it into the command input tool, and the execution Command pasting means for transferring only the command from which the command has been deleted from the command input tool to the terminal software, adding an execution command to the command displayed on the terminal software, and sending the command to the maintenance target device. Command execution means for executing a command.

  According to the maintenance support system of the present invention, there is provided a command correcting means for correcting a command displayed on the command input tool.

  According to the maintenance support system of the present invention, the command pasting means controls that the command cannot be retransmitted after the command is transferred.

  According to the maintenance support system of the present invention, the command pasting means limits the transfer of the command according to the priority order given by the command input tool.

  According to the maintenance support method of the present invention, in the maintenance support method for supporting the maintenance of the maintenance target terminal, the execution instruction is deleted from the command fetched from the procedure manual and fetched into the command input tool, and the execution instruction is deleted. Only the command is transferred from the command input tool to terminal software, an execution instruction is added to the command displayed on the terminal software, and the command is transmitted to a maintenance target device to execute the command. .

  According to the maintenance support method of the present invention, the command displayed on the command input tool is corrected.

  According to the maintenance support method of the present invention, after the command transfer, the command is controlled so that it cannot be retransmitted.

  According to the maintenance support method of the present invention, the transfer of the command is limited according to the priority order given by the command input tool.

  According to the maintenance support program of the present invention, in the maintenance support program for controlling the maintenance support of the maintenance target terminal device, the function of deleting the execution instruction from the command taken from the procedure manual and taking it into the command input tool, A function for transferring only the command from which the execution instruction has been deleted from the command input tool to the terminal software, and an execution instruction is added to the command displayed in the terminal software, and the command is transmitted to the maintenance target device. And a function of executing the function.

  According to the present invention, in the CLI maintenance terminal, when the contents of the procedure manual are input (pasted) to the command input tool, the execution instruction is deleted and pasted. Even when “Copy” is pressed by the command input tool and the command is transferred to the terminal software, the execution command is not added, so the command is not immediately executed on the terminal software. Since the maintenance worker can confirm the contents of the command again before execution, it is possible to prevent erroneous execution of the command to the computer system. Here, the execution instruction often uses a line feed code, and in the present invention, “CR” (Carriage Return: line return), “LF” (Line Feed: line feed) and the like are regarded as execution instructions.

  Further, since the maintenance worker adds an execution instruction on the terminal software and the command is executed for the first time, the maintenance worker can execute the command at an arbitrary timing. For example, it is effective when it is necessary to wait for the end of a certain process and execute the next command.

  In addition, the commands described in the procedure manual can be copied and input to the terminal software via the command input tool, so that maintenance workers can save labor by manually inputting long commands or inputting a large number of commands. And work efficiency can be improved. Further, since manual input by the maintenance worker is omitted, it is possible to prevent erroneous characters such as typing mistakes that are likely to occur during manual input.

  Further, since the command already entered in the command column can be corrected without adding an execution instruction, correction can be facilitated even if there is a mistake in the description of the procedure manual.

  In addition, since the command input tool can easily copy and input to the terminal software by pressing the transfer key, maintenance work can be easily executed even when a large number of commands are input.

  Further, the re-insertion prevention function prevents the command from being executed twice by mistake because it cannot be locked and re-pressed after the transfer key is pressed. Further, by changing the color of the executed command column, it is possible to visually check the executed command and visually understand the command to be input next.

  In addition, since the transfer key that can be pressed is determined according to the command input order, it is possible to prevent the command from being executed in an incorrect input order.

  Further, since the time when the transfer key is pressed is displayed, the maintenance worker can confirm the work execution schedule. Moreover, since the executed command and the execution time can be recorded as records, it can be used for verification after work. Further, by using the memo function of the command input tool, a comment can be added to the record.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
As shown in FIG. 1, in the maintenance support system of the present invention, a maintenance worker (not shown) connects to the communication network 2 for each computer system (maintenance target device) 3 connected to the communication network 2. Maintenance is performed by operating the maintenance terminal 10 and executing a maintenance command.

  The maintenance terminal 10 includes an arithmetic control unit 11, a storage device 12, an input device 13, a display device 14, and a communication device 15. The shape of the housing of the maintenance terminal 10 may be any of a desktop type and a laptop type, and is not particularly limited. Also, the type of OS (Operating System) of the maintenance terminal 10 is not particularly limited as long as the command input tool 30 described later operates.

  The arithmetic control unit 11 is composed of a CPU or the like, transmits and receives signals from various devices such as the storage device 12, and controls the operation of the maintenance terminal 10, specifically, a procedure manual creation means 21, which will be described later, The functions of the procedure manual fetch unit 22, the execution command deletion unit 23, the procedure manual display control unit 24, the command correction unit 25, the command pasting unit 26, the command display control unit 27, and the command execution unit 28 are executed.

  The storage device 12 includes a volatile memory (Random Access Memory: RAM), a nonvolatile memory (nonvolatile memory), a hard disk (hard disk), and the like. The RAM is used for temporary storage during operation of the maintenance terminal 10, and data that is not deleted such as initial settings of the maintenance terminal 10 is stored in the hard disk or the nonvolatile memory. The application software is installed on the hard disk and expanded in the RAM when the program is executed.

  The input device 13 is a device such as a keyboard and a mouse for inputting information to the maintenance terminal 10 when operated by a maintenance worker.

  The display device 14 is a device for displaying the operation status of the maintenance terminal 10. The shape and display form of the liquid crystal display, projector, etc. are not particularly limited.

  The communication device 15 is a device for connecting the maintenance terminal 10 to the communication network 2 and performing bidirectional communication with the maintenance target device 3. If the communication network 2 is a general LAN or the Internet (registered trademark) communication network, the communication device 15 may be a general network adapter such as Ethernet (registered trademark), and is not particularly limited. It is not something.

  Next, the command input tool 30 and the terminal software 50 will be described. The command input tool 30 and the terminal software 50 are installed in the hard disk of the maintenance terminal 10, and are read from the hard disk at the time of calling the program, expanded in the RAM, and executed.

  The command input tool 30 is operated by the maintenance operator 7 during maintenance, and receives commands, corrects them, transfers them to terminal software, and the like. The command input tool 30 includes a plurality of command fields 31, a transfer key (“Copy” key) 32, a display field 33, a check box 34, a comment field 35, and a tab 36.

  The command column 31 is a column for inputting a maintenance command (command) to be transmitted to the maintenance target device 3. Input to the command field 31 includes a method of reading the contents of the procedure manual 40, a method of pasting by copy and paste, and a method of inputting directly from an input device such as a keyboard. In either input, the execution instruction is not added to the end of the line.

  When the transfer key 32 is pressed, the command input in the command field 31 is transferred to the terminal software 50. When the re-insertion prevention function is executed, the pressed transfer key 32 is changed so that the button cannot be pressed so that the re-press function cannot be used.

  The display column 33 displays functions that are currently implemented. In the present embodiment, since a re-insertion prevention function to be described later is implemented, “atOcne” is displayed in the display field 33.

  The function described in the display column 33 can be used by marking the check box 34 with an input device such as a keyboard or a mouse. For example, if the check box 34 is marked while “atOcne” is displayed in the display field 33, the re-entry prevention function works, and the transfer key 32 cannot be pressed again after the transfer key 32 is pressed. If the check box 34 is not marked, the re-entry prevention function does not work, so that even after the transfer key 32 is pressed, it can be pressed again and the command is transferred to the terminal software again.

The comment field 35 is a field in which characters / symbols can be directly input using the input device. The input characters are stored in the comment field 35 and the log file of the operation result.
The tab 36 stores a plurality of command fields 31, a plurality of display fields 33, a plurality of check boxes 34, and a comment field 35 as a group, switches between a plurality of tabs, captures and displays the procedure manual 40 for each tab. It has a function. The number of tabs 36 is not particularly limited.

  The terminal software 50 (shown in FIG. 5) is software that is used as a virtual terminal for input to the connected maintenance target device. The terminal software 50 transmits characters input from the input device (keyboard) to the connection target maintenance target device, and is connected. A function that only displays characters sent by the previous maintenance target device is realized. The terminal software 50 may be commercially available software and is not particularly limited.

  The procedure manual 40 (shown in FIG. 4) is electronic data describing commands, notes, and the like for the actual maintenance work for the maintenance target device 3 in chronological order. In the procedure manual 40, in addition to the command to be actually input, the target device name, the cautionary note, and the command may be given an order. The procedure manual 40 is created by a maintenance manager, a maintenance worker, and the like, and the contents are strictly examined by a plurality of persons. This is because a mistake in one character of the command may cause a large-scale computer failure. The procedure manual 40 is preferably created in a text data format that does not include character decorations. This is because the text data format can be recognized regardless of the model, can be transferred to other systems, and can be pasted to various terminal software without converting the character code.

[Explanation of means]
Next, an embodiment of the present invention will be described with reference to FIG.

  First, the procedure manual creation means 21 (step S1) creates the procedure manual 40. In the procedure manual 40, in addition to the command to be actually input, the target device name, a note, and the command to be input are described in chronological order. At the time of description, it is created by a maintenance manager, a maintenance worker, etc., and the contents are strictly examined by a plurality of persons. Further, the procedure manual 40 may be created by a terminal other than the maintenance terminal 10 and loaded into the maintenance terminal 10. At this time, the procedure manual 40 is not particularly limited to a creation application program such as a word processor or a text editor, but is desirably created in a text data format that does not include character decoration or the like. In text data format, characters can be recognized regardless of the model, and can be transferred to other terminals and systems, and can be pasted without converting the character code to various terminal software. is there.

  Next, the process proceeds to the procedure manual capturing means 22 (step S2). The procedure manual capturing unit 22 is a unit that captures the contents of the procedure manual 40 into the command input tool 30. First, the command input tool 30 stored (installed) in the storage device 12 of the maintenance terminal 10 is activated. When the command input tool 30 is activated, the tab 36 into which the procedure manual 40 is to be imported is selected by keyboard operation or mouse click. After selecting the tab 36, the command described in the procedure manual 40 is fetched from the procedure manual 40 to the command input tool 30 by pressing the [Import] button (not shown).

  Next, the process proceeds to the execution instruction deleting unit 23 (step S3). The commands that are taken into the command column 31 are commands excluding notes and numbers. Execution instructions (carriage return code), such as “CR” (Carriage Return), “LF” (Line Feed: line feed) added to the end of the command in the procedure manual 40, are deleted at the time of import. To do. Then, when pasting to the command column 31, an execution command cannot be added.

  Next, the process proceeds to the procedure manual display control means 24 (step S4). As shown in FIG. 4, the commands fetched into the command input tool 30 by the procedure manual fetching means 22 (S2) and the execution command deleting means 23 (S3) are displayed in the command column 31 line by line. .

  Next, the command correction means 25 (step S5) corrects the command displayed in the command column 31, changes the check box 34 whether it is checked, and inputs / deletes the comment column 35. Although the command in the command column 31 is corrected by keyboard input, it is impossible to input an execution command to the comment column 35 even if the correction is performed. This is to prevent the execution instruction from being added to the end of the command due to the correction. Further, by changing whether or not the check box 34 is checked, the maintenance worker can select whether to use or not use the function displayed in the display field 33. Since the content of the comment field 35 is not transmitted to the maintenance target device 3, an execution command can be added when inputting or deleting.

  Next, the command pasting means 26 (step S6) presses the transfer key 32 in response to the command to be transmitted from the command input tool 30 to the maintenance target device 3, so that the command in the command column 31 of the command input tool 30 is displayed. And transferred to the terminal software 50. At this time, no execution instruction is added to the end of the command transferred to the terminal software 50.

  Next, the command display control means 27 (step S7) transfers the command to the terminal software 50 and displays it on the terminal software 50 as shown in FIG. Since the execution command is not added to the end of the displayed command, the maintenance worker visually confirms the content of the command. If there is a defect in the contents of the command, the maintenance worker can operate the keyboard on the terminal software 50 to correct the defect in the command.

  Finally, the command execution means 28 (step S8) presses the “Enter” key that is an execution instruction to the command displayed on the terminal software 50, adds the execution instruction, and executes the command. The executed command is executed for the maintenance target device 3. The execution command may be input other than the “Enter” key.

  When the processing of the command execution means 28 (step S8) is completed, the operator returns to the command pasting means (step S6) and presses the transfer key 32 for the command to be transferred to the terminal software 50 next. As described above, by repeating Steps S6 to S8, the commands taken into the command input tool 30 can be sequentially transferred to the terminal software 50 to perform maintenance work.

  As described above, the configuration is such that the execution instruction is not added to the end of the command as in steps S1 to S8, so that the immediate execution of the command is suppressed with respect to the maintenance target device 3, and the maintenance operator can use the terminal software 50. Thus, it is possible to detect / correct a command trap, so that it is possible to prevent a command including erroneous contents from being transferred to the maintenance target device 3. Even if a large number of commands are described in the procedure manual 40, the worker can perform a maintenance operation by inputting a large number of commands safely and quickly.

[Re-insertion prevention function]
Further, the function displayed in the display field 33 can be used depending on whether or not the check box 34 is checked. In this embodiment, a re-input prevention function is implemented. If the check box 34 is checked, “at Once” described in the display field 33 is activated, and a process that cannot be pressed again is performed on the pressed transfer key 32. As a result, the command in the corresponding command column 31 is not transferred to the terminal software 50. Processing that cannot be pressed includes, for example, processing that disables pressing the transfer key button, changes from “Copy” button display to character display, changes display color, changes to other display (time etc.), etc. Is preferred. It is also preferable to change the color of the corresponding command field 31 and visually appeal that the pasting has been completed. In this way, re-input of the same command is prevented.

[Order restriction function]
Further, since maintenance work is performed in the order described in the procedure manual, it is a normal procedure to input in order from the top to the bottom of the command column 31. However, an accident may occur when a maintenance worker accidentally presses the transfer key 32 out of order. Therefore, the storage device 12 stores the position of the command column 31 where the transfer key 32 was last pressed, and even if the transfer key 32 of the command column 31 to be input next is pressed, the command in the corresponding command column 31 is not displayed. , A function is provided for limiting the transfer to the terminal software 50. In this way, an error in the command input sequence is prevented.

Second Embodiment
The maintenance support system described above can be realized by hardware, software, or a combination thereof. The maintenance support method performed by the above maintenance support system can also be realized by hardware, software, or a combination thereof. Realization by software means that the computer is realized by building each unit shown in FIG. 3 on software by reading and executing a program from a storage medium or the like.

  The program can be stored in various types of recording media and supplied to a computer. Examples of the recording medium include a magnetic recording medium (floppy (registered trademark) disk, magnetic tape, hard disk drive, etc.), a magneto-optical recording medium (CD-ROM, DVD-ROM, BL-ROM, etc.), semiconductor memory (mask). ROM, PROM, EPROM, flash ROM, RAM (random access memory, etc.). The program can also be supplied to the computer via a telecommunication line.

  Hereinafter, the case where the maintenance support process is executed by executing the maintenance support program of the present invention will be described with reference to FIGS.

  First, the procedure manual 40 is created (step S101). In the procedure manual 40, in addition to the command to be actually input, the target device name, a note, and the command to be input are described in chronological order. At the time of description, it is created by a maintenance manager, a maintenance worker, etc., and the contents are strictly examined by a plurality of persons. Further, the procedure manual 40 may be created by a terminal other than the maintenance terminal 10 and loaded into the maintenance terminal 10. At this time, the procedure manual 40 is not particularly limited to a creation application program such as a word processor or a text editor, but is desirably created in a text data format that does not include character decoration or the like. In text data format, characters can be recognized regardless of the model, and can be transferred to other terminals and systems, and can be pasted without converting the character code to various terminal software. is there.

  Next, the description content of the procedure manual 40 is taken into the command input tool 30 (step S102). First, the command input tool 30 stored (installed) in the storage device 12 of the maintenance terminal 10 is activated. When the command input tool 30 is activated, the tab 36 into which the procedure manual 40 is to be imported is selected by keyboard operation or mouse click. After selecting the tab 36, the command described in the procedure manual 40 is fetched from the procedure manual 40 to the command input tool 30 by pressing the [Import] button (not shown).

  When the acquisition of the procedure manual 40 is successful (YES in step S102), what is taken into the command column 31 is a command excluding a note and a number. A line feed code, such as “CR” or “LF”, which is a command execution instruction added to the end of the command in the procedure manual 40, is deleted at the time of capture. Then, when pasting in the command field 31, an execution command cannot be added (step S103). Further, if the import of the procedure manual 40 has failed (NO in step S102), the process returns to step S101.

  Next, the command fetched by the command input tool 30 is displayed in the command column 31 line by line as shown in FIG. 4 (step S104).

  Here, the command displayed in the command column 31 can be corrected, the check box 34 can be checked or not checked, and the comment column 35 can be input or deleted (step S105). Although the command in the command column 31 is corrected by keyboard input, it is impossible to input an execution command to the comment column 35 even if the correction is performed. This is to prevent the execution instruction from being added to the end of the command due to the correction. Further, by changing whether or not the check box 34 is checked, the maintenance worker can select whether to use or not use the function displayed in the display field 33. Since the content of the comment field 35 is not transmitted to the maintenance target device 3, an execution command can be added when inputting or deleting.

  Then, by pressing the transfer (“Copy”) key 32 for a command to be transmitted from the command input tool 30 to the maintenance target device 3, the command in the command column 31 of the command input tool 30 is transferred to the terminal software 50. Transferred (step S106). At this time, an execution instruction cannot be added to the end of the command transferred to the terminal software 50.

  Here, when the above-described order restriction function is implemented (YES in step S107), the command input order on the command input tool 30 is checked, and the command in the command column 31 where the transfer key 32 is pressed is the previous time. If the transferred commands are correct in the next order (YES in step S108), they are displayed on the terminal software 50. At this time, since the execution instruction is not added, the command enters an execution standby state (step S109), and enters a state of waiting for input to the terminal software 50 of the maintenance worker.

  If the order restriction function is not implemented (NO in step S107), the command in the command column 31 in which the transfer key 32 is pressed is not displayed in the terminal software without checking the command input order on the command input tool 30. 50 is displayed.

  If the command in the command column 31 where the transfer key 32 is pressed is incorrect in the next order of the previously transferred command (NO in step S108), the transfer is stopped and the process returns to step S105.

  During the command execution standby state (step S109), the maintenance worker visually confirms the content of the command. If there is a defect in the contents of the command, the maintenance worker can operate the keyboard on the terminal software 50 to correct the defect in the command.

  If the command is normal (YES in step S110), the maintenance worker presses the “Enter” key with respect to the command displayed on the terminal software 50, adds an execution command (line feed code), and executes the command. Execute (Step S111). The executed command is executed for the maintenance target device 3. The command may be executed by key input other than the “Enter” key.

  If the command is not normal (NO in step S110), the maintenance worker deletes the command on the terminal software 50 and returns to step S105.

  Here, when the above-described re-entry prevention function is implemented (YES in step S112), when the check box 34 corresponding to the command column 31 where the transfer key 32 is pressed is checked (in step S113). (YES), the transfer key 32 is processed so that it cannot be pressed again (step S114), and the process ends. In FIG. 4, the display of the transfer key 32 is changed to the time when the display is performed. In addition, the color of the command column 31 is changed to appeal visually.

  Further, when the re-entry prevention function is not implemented (NO in step S112), and when the check box 34 corresponding to the command column 31 where the transfer key 32 is pressed is not checked (NO in step S113). Does not perform the process of the re-insertion prevention function, and ends.

  As described above, according to the present invention, in the CLI maintenance terminal, when the contents of the procedure manual are input (pasted) to the command input tool, the execution instruction is deleted and pasted. Even when “Copy” is pressed by the command input tool and the command is transferred to the terminal software, the execution command is not added, so the command is not immediately executed on the terminal software. Since the maintenance worker can confirm the contents of the command again before execution, it is possible to prevent erroneous execution of the command to the computer system.

  Further, since the maintenance worker adds an execution instruction on the terminal software and the command is executed for the first time, the maintenance worker can execute the command at an arbitrary timing. For example, it is effective when it is necessary to wait for the end of a certain process and execute the next command.

  In addition, the commands described in the procedure manual can be copied and input to the terminal software via the command input tool, so that maintenance workers can save labor by manually inputting long commands or inputting a large number of commands. And work efficiency can be improved. Further, since manual input by the maintenance worker is omitted, it is possible to prevent erroneous characters such as typing mistakes that are likely to occur during manual input.

  Further, since the command already entered in the command column can be corrected without adding an execution instruction, correction can be facilitated even if there is a mistake in the description of the procedure manual.

  In addition, since the command input tool can easily copy and input to the terminal software by pressing the transfer key, maintenance work can be easily executed even when a large number of commands are input.

  Further, the re-insertion prevention function prevents the command from being executed twice by mistake because it cannot be locked and re-pressed after the transfer key is pressed. Further, by changing the color of the executed command column, it is possible to visually check the executed command and visually understand the command to be input next.

  In addition, since the transfer key that can be pressed is determined according to the command input order, it is possible to prevent the command from being executed in an incorrect input order.

  Further, since the time when the transfer key is pressed is displayed, the maintenance worker can confirm the work execution schedule. Moreover, since the executed command and the execution time can be recorded as records, it can be used for verification after work. Further, by using the memo function of the command input tool, a comment can be added to the record.

  The present invention can be embodied in many forms without departing from its essential characteristics. Therefore, it is needless to say that the above-described embodiment is exclusively for description and does not limit the present invention.
