Description

  The present invention relates to an information processing program, an information processing apparatus, and an information processing method.

  There is a case where a business system with generation of a document including a graphic is constructed by incorporating an original function addition add-in (add-in program) into a commercially available graphic drawing application (for example, Microsoft Visio (registered trademark)). In addition, in order to automate the business, an intermediate tool that automatically makes a processing request to the function addition add-in may be included in the business system.

  In such a business system, business process flowcharts and Gantt charts are created using the basic functions of the graphic drawing application, and document creation support and drawing check functions (checking of unification of notations, etc.) are provided by function addition add-ins. Realized.

  When using a business system, a file that is the original data of a document to be created is often processed continuously. In this case, depending on the function addition add-in, the heap memory (JAVA (registered trademark) heap memory, etc.) allocated for processing is consumed every time processing is performed, and the process may end abnormally due to a lack of space. is there. The heap memory is mainly used for opening a file.

  FIG. 1 shows an example of a business system, which includes an intermediate tool, a graphic drawing application, and a function addition add-in. The intermediate tool inputs a file to be processed and makes a processing request to the function addition add-in.

  FIG. 1A shows a case where the heap memory under the management of the function addition add-in is free and processing is performed normally. FIG. 1B shows a case where there is no more free space in the heap memory managed by the function addition add-in. FIG. 1C shows a case where further processing is continued, the heap memory is insufficient, a memory leak occurs, and the graphics drawing application and the function addition add-in are abnormally terminated.

  On the other hand, a technique for calculating a resource amount of a program by tracking an object unique to the program operating on a computer is disclosed (see, for example, Patent Document 1). In addition, a technique is disclosed in which a memory usage amount used in an application is measured in real time by adding a code that records application information in a thread at the beginning of a method included in a class file (for example, Patent Document 2). Etc.).

  As described above, in the conventional business system, when a plurality of files are continuously processed, abnormal termination may occur at an unexpected timing, and continuous automatic processing is interrupted. A restoration process is required and a processing delay occurs, which is not preferable.

  Therefore, an object of one aspect is to prevent abnormal termination of an application.

  In one embodiment, when a file is input to an application that performs predetermined processing, a cumulative value of the number of files and a cumulative value of the file size of a file that has been processed after the previous activation of the application are acquired, and the file It is determined whether the cumulative value of the number reaches a first threshold value or the cumulative value of the file size reaches a second threshold value. Then, after the activation is completed, the application is requested to process the file, and the process is executed by the computer.

  Abnormal termination of the application can be prevented.

<Configuration>
FIG. 2 is a diagram illustrating a functional configuration example of the information processing apparatus 1. In FIG. 2, the information processing apparatus 1 includes a business system 101, an input folder 111, and an output folder 112. The business system 101 has a function of generating a document in a predetermined format based on a file saved in the folder 111 and storing it in the folder 112.

  The business system 101 includes an intermediate tool 102, a function addition add-in 108, and a graphic drawing application 109. The graphic drawing application 109 is a commercially available application (for example, Microsoft Visio), and has a function of generating and editing a document including a graphic. The function addition add-in 108 is an add-in program incorporated in the graphic drawing application 109, and adds functions to the graphic drawing application 109 to realize document creation support, a drawing check function (check of unification of notations, etc.) and the like. . The function addition add-in 108 outputs (saves) the generated document to the folder 112. The intermediate tool 102 has a function of automatically making a processing request to the function addition add-in 108 in order to automate the work.

  The intermediate tool 102 includes a folder monitoring unit 103, an abnormal end predetermination unit 104, an end / restart unit 105, a processing request unit 106, and a file deletion unit 107. The folder monitoring unit 103 has a function of monitoring the input folder 111 and notifying the subsequent abnormal end predetermination unit 104 when a new file is saved. Note that the function addition add-in 108 and the graphics drawing application 109 process files one by one, and input of a new file is in a standby state after completion of processing, so that monitoring of the folder 111 can be input after completion of processing. It is enough to go to.

  The abnormal termination advance determination unit 104 has a function of determining in advance whether or not there is a possibility that the function addition add-in 108 and the graphic drawing application 109 may abnormally terminate by processing a new file. Details of the determination will be described later. The termination / restart unit 105 has a function of terminating and restarting the function addition add-in 108 and the graphic drawing application 109 when the abnormal termination predetermination unit 104 determines that there is a possibility of abnormal termination. . The processing request unit 106 processes an unprocessed file stored in the folder 111 with respect to the function addition add-in 108 immediately after termination / reboot is required, and when termination / reboot is performed, after the reboot. It has a function to make a request. The file deletion unit 107 has a function of deleting a file that has been processed by the function addition add-in 108 and the graphic drawing application 109 from the folder 111. If there is no need to delete a file from the folder 111, the file deletion unit 107 can be omitted.

  In addition, although the aspect in which the business system 101 is realized in a stand-alone form on the information processing apparatus 1 has been described, a form in which the business system 101 is constructed on a server apparatus and the business system 101 is used via a network from a client terminal. It is good.

  FIG. 3 is a diagram illustrating a hardware configuration example of the information processing apparatus 1. In FIG. 3, the information processing apparatus 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, and a RAM (Random Access Memory) 13 connected to each other via a bus 17. The information processing apparatus 1 also includes a hard disk drive (HDD) / solid state drive (SSD) 14, a connection interface (I / F) 15, and a communication interface 16. The CPU 11 performs overall control of the operation of the information processing apparatus 1 by executing a program stored in the ROM 12 or the HDD / SSD 14 or the like using the RAM 13 as a work area. The connection I / F 15 is an interface with a device connected to the information processing apparatus 1. The communication I / F 16 is an interface for communicating with other information processing apparatuses via a network.

  The functions of the information processing apparatus 1 described in FIG. 2 are realized by executing a predetermined program in the CPU 11. The program may be acquired via a recording medium, may be acquired via a network, or may be embedded in a ROM. Data to be referred to / updated during processing is held in the RAM 13 or the HDD / SSD 14.

<Operation>
FIG. 4 is a sequence diagram showing a processing example of the above embodiment. In FIG. 4, when the intermediate tool 102 of the business system 101 is activated and starts processing, it initializes processing variables (number of processing files, processing file size) (step S101).

  Next, the intermediate tool 102 of the business system 101 performs the following processing in a standby state in which the function addition add-in 108 and the graphics drawing application 109 have completed processing of the previous file.

  That is, the intermediate tool 102 of the business system 101 monitors the input folder 111 (step S102). When the user saves the file to be processed in the folder 111 (step S103), the intermediate tool 102 acquires the file size of the next file to be processed saved in the folder 111 (step S104). The file size can be obtained from the file properties.

  Next, the intermediate tool 102 of the business system 101 updates processing variables (the number of processing files and the processing file size) (step S105), and performs abnormal termination advance determination based on the updated variables (step S106).

  If the intermediate tool 102 of the business system 101 determines that there is a possibility of abnormal termination, the function addition add-in 108 and the graphics drawing application 109 are terminated and restarted (step S107), and a processing variable (processing file) Number and processing file size) are updated (step S108). If it is determined that there is no possibility of abnormal termination, termination / restart and variable update are not performed.

  Next, the intermediate tool 102 of the business system 101 designates a file to be processed and makes a processing request to the function addition add-in 108 (step S109). In response to this, the function addition add-in 108 generates a document together with the graphic drawing application 109 (step S110), and saves the generated document file in the output folder 112 (step S111). Thereafter, the user obtains a document file from the output folder 112 (step S112).

  FIG. 5 is a flowchart illustrating a processing example of the intermediate tool 102 in the information processing apparatus 1. In FIG. 5, when the intermediate tool 102 is activated and starts processing, it initializes the number of processing files and the processing file size, which are processing variables (step S121). That is, both the number of processing files and the processing file size are set to “0”.

  Next, the folder monitoring unit 103 of the intermediate tool 102 monitors whether or not an unprocessed file exists in the input folder 111 (step S122), and repeats the monitoring if it does not exist (No in step S122).

  If there is an unprocessed file in the input folder 111 (Yes in step S122), the abnormal end advance determination unit 104 acquires the file size of the file to be processed (step S123).

  Next, the intermediate tool 102 adds 1 to the number of processing files, and adds the file size of the processing target file to the processing file size (step S124).

Next, the abnormal end pre-determination unit 104 of the intermediate tool 102 determines whether the number of processed files has reached a predetermined number that is a threshold, or whether the processed file size has reached a predetermined size that is a threshold (step S125). ). Here, as the predetermined number serving as the threshold for the number of processing files and the predetermined size serving as the threshold for the processing file size, values obtained from the actual operation results are used. For example, it is known that the JAVA heap memory usage amount managed by the function addition add-in 108 reaches the maximum and terminates abnormally in the following cases.
-When files with a file size of 480 KB or less are processed continuously, the number of processed files reaches 65.-When files with a file size larger than 480 KB are processed continuously, the total processing file size is 35 MB. When

  In this example, the predetermined number serving as the threshold for the number of processing files is “65”, and the predetermined size serving as the threshold for the processing file size is “35 MB”.

  When it is determined that neither the number of processing files nor the processing file size reaches the threshold value (No in step S125), the processing request unit 106 of the intermediate tool 102 specifies the file to the function addition add-in 108 and requests processing ( Step S128). The function addition add-in 108 and the graphics drawing application 109 process the specified file, and save the generated document in the output folder 112. Then, the file deletion unit 107 of the intermediate tool 102 deletes the processed file from the input folder 111 (step S129).

  If it is determined that either the number of processing files or the processing file size has reached the threshold (Yes in step S125), the end / restart unit 105 of the intermediate tool 102 ends the figure drawing application 109 and the function addition add-in 108. And restarts (step S126). As a result, the heap memory managed by the function addition add-in 108 is cleared and reset.

  Next, the intermediate tool 102 resets the number of processing files to “1” and the processing file size to the processing target file size (step S127).

  Next, the process request unit 106 of the intermediate tool 102 requests the process by specifying a file to the function addition add-in 108 (step S128). The function addition add-in 108 and the graphics drawing application 109 process the specified file, and save the generated document in the output folder 112.

  Next, the file deletion unit 107 of the intermediate tool 102 deletes the processed file from the input folder 111 (step S129).

  Thereafter, the process for the current file is awaited, and the process is repeated from the monitoring of the folder 111 (step S122).

  In this way, it is determined whether the heap memory usage reaches the maximum before processing the file, and if it reaches the maximum, restarting and resetting the processing will cause the file to be processed. The risk of abnormal termination due to insufficient memory can be reduced. In addition, the configuration is such that the determination is made using the cumulative number of files to be processed and the total file size, and termination and restart are performed as necessary. There is no need for coordination, and the existing mechanism can be applied without significant modification.

<Summary>
As described above, according to this embodiment, abnormal termination of an application can be prevented.

  In order to prevent abnormal termination of the application, it is conceivable to directly monitor the memory usage of the application and take some measures before the heap memory is insufficient. However, in that case, it is necessary to incorporate a complicated mechanism into the application (including the function addition add-in), and it is difficult to apply. In addition, as a matter of course for commercially available graphics drawing applications themselves, it may not be easy to modify function-added add-ins specialized for business systems due to the nature of business, and there may be no software that can be replaced. It is difficult to apply. For example, for a function addition add-in for a business meeting a legal request, the modification affects the reliability of the business, so the procedure for performing the modification is complicated. In this respect, according to the present embodiment, it is not necessary to modify the application for monitoring the memory, and application to an existing application is easy.

  In the above, it demonstrated by preferred embodiment. While specific embodiments have been illustrated and described herein, it will be apparent that various modifications and changes may be made thereto without departing from the broad spirit and scope as defined in the claims. . That is, it should not be construed as being limited by the details of the specific examples and the accompanying drawings.
