Abstract

PROBLEM TO BE SOLVED: To make a verifier able to easily verify the layout of a data file as a dump target without being consciout of it. SOLUTION: A dump program generating part 2 generates a dump program 16 for sectioning a result of dump processing into data item units and outputting them, on the basis of, for example, file layout definition information 11 indicating the organization of a dump target data file 17 and saves it in a storing part 4. A program executing part 3 then applies the data file 17 to the dump program 16 saved in the storing part 4 to execute dump processing. This sets all necessary information such as a layout definition in advance in the dump program 16 itself, so that a verifier, when executing the dump processing, can execute it only by specifying the necessary data file 17 and without inputting the layout definition information in each operation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for outputting a file dump, a program for generating a dump program for causing a computer to function as a means for generating a dump program, and a computer-readable recording medium. It is suitable for use in a file dump output method and apparatus for outputting a file dump in a list format divided into data item units.

[0002]

2. Description of the Related Art In general, when testing a computer system (program) or examining abnormalities, etc., the developed computer system generates test data, inputs the test data to the system, and outputs data output as a result of program processing of the system. Comparison and verification with data (test oracle) expected as a correct answer is performed. At this time, dump these data files (DUMP) to confirm the consistency of the test data input to the system and the processing result data output.
It is generally done to output.

Conventionally, various file dump output tools have been provided, but most of them are of a type that outputs the contents of data files in hexadecimal code (hereinafter referred to as a hexa-DUMP tool). Was. Also, as described in, for example, Japanese Patent Application Laid-Open No. H11-272433, some data files are divided into items and output in a list format (hereinafter referred to as a list DUMP tool). Is provided.

The latter list DUMP tool reads layout definition information defining the layout of data files (item names, attribute types, digits, etc. of individual data items) in addition to the data files to be dumped. Then, the list DUMP tool analyzes the definition information, develops individual item names into a table, applies the data values in the data file to them, and outputs them.

[0005]

However, with the conventional file dump output tool, it is not easy to accurately grasp the value of the data item in the data file regardless of which type is used. A great deal of effort was required to test and verify the development. for that reason,
There is a problem that this is a hindrance to improving the productivity and quality of the program.

That is, in the conventional hexa-DUMP tool, the contents of a data file are simply output in hexadecimal code, and therefore, at a glance, the delimitation of data items cannot be recognized. Therefore, it is necessary for the verifier to look at the hexadecimal code string by dividing it by the number of digits (the number of characters) of the data item, which is extremely inefficient. In addition, since the user works to follow a similar number sequence with his / her eyes, it is easy to make mistakes and it is difficult to perform accurate verification.

On the other hand, in the conventional list DUMP tool,
In order for the tool to be able to determine the layout of the data file, the verifier needs to input layout definition information and the like separately from the data file to be dumped each time. Therefore, not only is the input operation cumbersome, but also the problem is that the dump cannot be performed unless the verifier who intends to perform the dump knows the layout definition of the data file.

Further, in the conventional list DUMP tool,
Since the contents of the data file are divided into items and output, the breaks of data items can be seen at a glance,
The dump output result is easier to see than the UMP tool. However, when a plurality of data exists in one data file and their layouts are different from each other, or when a so-called multi-layout data file is dumped, the data item delimiters cannot be accurately detected, resulting in an incorrect data item. There was a problem that the result was output.

That is, the conventional list DUMP tool does not have a function of determining a plurality of layouts.
As a result, only one data layout can be recognized,
For one data file, all the data in the data file is output with the same layout. Therefore, when the data file of the multi-layout is dumped, the data of the first data is dumped according to the first recognized layout.
Since the data after the first case is also output, the data items are separated at an incorrect place in the second and subsequent cases.

The present invention has been made in order to solve such a problem, and verifies the layout of a target data file by accurately grasping the value of a data item without the verifier being particularly conscious of the layout. Is to be able to be easily performed. It is another object of the present invention to output a dump list that is easy to read by accurately editing even a multi-layout data file in data item units.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) First, a first embodiment of the present invention will be described with reference to the drawings. FIG.
FIG. 2 is a block diagram illustrating a functional configuration of the file dump output device according to the first embodiment.

As shown in FIG. 1, the file dump output device 1 according to the present embodiment includes a dump program generation unit 2, a program execution unit 3, and a storage unit 4. The dump program generation unit 2 generates the file layout definition information 1
1. Input various information such as a copy phrase 12, a dump program skeleton source 13, and a control parameter 14,
The dump program 16 is automatically generated by executing the dump program generation program 15 using these pieces of information.

The dump program 16 generated by the dump program generator 2 is stored in the storage unit 4 such as a hard disk. That is, the dump program generation unit 2
Includes both the dump program generating means and the recording means of the present invention. The program execution unit 3 executes the dump program 16 stored in the storage unit 4, edits the data file 17 to be dumped in data item units, and outputs it as a dump list 18 that is easy to see.

The above-mentioned dump program generation program 1
5 is, for example, the RAM or RO of the file dump output device 1
M or stored in a hard disk or the like. Further, the dump program generation program 15 is recorded on a recording medium such as a CD-ROM, and
To the dump program generation unit 2
May be realized.

The dump program generation program 15
In addition to the CD-ROM, a floppy (registered trademark) disk, a magnetic tape, an optical disk, a magneto-optical disk, a DVD, a non-volatile memory card, and the like can be used as a recording medium for recording the information. Further, in order to use the file dump output device 1 of the present embodiment in a network environment, all or a part of the dump program generation program 15 may be executed by another computer.

Although the storage unit 4 is provided in the file dump output device 1 here, a recording medium (for example, a compact disk, a floppy disk, an optical disk,
The storage unit 4 may be composed of a magneto-optical disk, a DVD, or the like. Further, the storage unit 4 may be provided in an external host computer or the like, and may be configured to be arbitrarily accessible via a network.

The above-described dump program generation unit 2 and program execution unit 3 are actually provided by the C
The dump program generation unit 2 is realized by the operation of the dump program generation program 15 stored in the RAM or the ROM as described above. The program execution unit 3 is realized by the operation of the dump program 16 stored in the storage unit 4.

As a method of using the file dump output device 1 configured as described above, a person who has expertise in the layout (file organization) of a data file can use file layout definition information 11 for various types of data files. Various kinds of information such as a copy phrase 12, a dump program skeleton source 13, and a control parameter 14 are input to cause the apparatus 1 to automatically generate a dump program 16 and store it in the storage unit 4. Thereafter, the verifier who actually dumps the data file 17 to be dumped selects an appropriate dump program 16 from the storage unit 4 according to the type of the data file 17 to be dumped, and performs dump processing by the program execution unit 3. Execute

Hereinafter, the details of each component described above will be described. The file layout definition information 11 includes a copy phrase name, individual data item names in a data file (Japanese notation and alphanumeric notation for a programming language), an attribute type indicating a type of each data, a number of digits indicating a number of characters, and repetition. Information defining the file organization such as the number of times. This is also called record definition information.

FIG. 2 shows the file layout definition information 11
FIG. 3 is a diagram showing a format example. As shown in FIG.
In the file layout definition information 11, the file includes information such as a level number of each data item included in the data file, a Japanese item name, an alphanumeric item name, an attribute type, the number of digits, the number of decimal places, and the number of repetitions. The organization is defined. FIG. 3 is a diagram showing a specific example of the file layout definition information 11 using the format as shown in FIG.

The copy phrase 12 is defined as a record that can be handled by the program by dividing the contents of the data file according to the attribute type and the number of digits. This copy phrase 12 can be automatically generated from the file layout definition information 11.

FIG. 4 is a diagram showing an example of the copy phrase 12. Here, an example of a copy phrase when COBOL is used as a programming language is shown. The copy phrase 12 shown in FIG. 4 is generated from the file layout definition information 11 shown in FIG.

In FIG. 4, a data item having a level number “01” and an item name “KOJIN-REC.” And a data item having a level number “02” and an item name “SEINENGAPPI” are:
Group item (a data item defined with a hierarchy. For example, the item name "SEINENGAPPI" is "NEN""TUKI""HI"
Are the lower layers), and the other data items are basic items. In this example, in the basic item, any one of the attribute types of X type capable of handling alphanumeric characters and special characters and nine types capable of handling only numbers is set.

Dump program skeleton source 13
Is a source code having only a basic program (a process of outputting a data item) serving as a skeleton of the dump program 16 to be generated. The dump program skeleton source 13 is different for each file type such as FB type in which each data in a data file is fixed length, VB type in which each data is variable length, and VSAM type in which a unique key is required for data reading. Prepare

By selectively using the dump program skeleton source 13 of any file type,
The dump program generator 2 automatically generates a dump program 16 of a type suitable for each type.
It is not necessary to specify the record length and change the file length by the past method. In addition, when a use JCL is created when the dump program 16 is executed, it is possible to cope with the situation simply by specifying a file name.

The control parameters 14 include parameters for controlling generation of the dump program 16 and parameters for controlling items of the data file 17 to be dumped. FIG.
FIG. 5A is a diagram illustrating an example of a control parameter 14 used in the present embodiment. FIG. 5A illustrates a generation control parameter.
FIG. 5B shows parameter for item control.

As shown in FIG. 5A, there are three generation control parameters: a file type, a program ID, and a copy phrase name. In the file type parameter,
FB type = “1”, VB type = “2”, VSAM type = “3”
Set any value of In the parameter of the program ID, information for identifying the data file corresponding to the file layout definition information 11 is set. The copy phrase name parameter sets a copy phrase that can be referred to by a plurality of dump programs. In the case of the copy phrase 12 shown in FIG. 4, the file type = "1" and the program ID
= "KOJINFILE" (optional), copy phrase name = "KOJIN".

As shown in FIG. 5B, there are two item control parameters: an item name and the number of digits. If no parameter is set here, all data items included in the data file are individually set as dump output items. By setting this parameter arbitrarily, multiple data items It is possible to control so as to collect them into dump output items.

For example, in the example of FIGS. 3 and 4, when the item control parameter is set so that the number of digits of the item name “SEINENGAPPI” is 12 digits, the data items “NEN”, “T
UKI "" HI "will no longer be set as a separate dump output item, meaning that year / month / day will not be output as separate data items, Will be output.

The dump program generation unit 2 executes the file layout definition information 11 and the copy phrase 1 described in detail above.
2. The dump program 16 is automatically generated using the dump program skeleton source 13 and the control parameters 14. The operation at that time will be described in detail with reference to the flowchart of FIG.

In FIG. 6, first, the dump program generator 2 reads and recognizes the file type set by the generation control parameters of FIG. 5A (step S1). Since the creation of the dump program 16 to be generated differs depending on the file type, the type of the dump program 16 to be generated is grasped by reading this parameter.

Next, the program ID set by the generation control parameters of FIG. 5A is set to the ID of the dump program 16 to be generated (step S2). Conventionally, the ID of the target data file could not be recognized. However, by setting the program ID representing the identification name of the data file in the dump program 16 as in the present embodiment, the generated dump program Which data file 16 corresponds to can be easily confirmed by the ID. This makes it possible to easily confirm the target file when the verifier selects the dump program 16 and confirms the dump output result.

Next, the copy phrase set by the generation control parameters shown in FIG. 5A is set so as to be expanded by the generated dump program 16 (step S3).
In the conventional list DUMP tool using a copy clause, each item of the copy clause is used as a data value in the dump program, so that output control can be performed by selecting a target item and determining the value of the item. Did not. On the other hand, according to the present embodiment, since the actual item of the copy phrase set by the parameter of the copy phrase name is used for the process description of the dump program 16, the output control of the target item (a specific example is the second example). (Described in the embodiment) can be performed.

Next, by taking in and setting all the item names and the number of digits set by the item control parameters in FIG. 5B, the individual basic items belonging to the lower layer of the group item are dumped. (Step S4). In the conventional list DUMP tool, only dump output items can be individually specified for a plurality of data files. However, according to the present embodiment, data items that are likely to be commonly used for a plurality of data files Can be commonly specified by specifying a parameter when the dump program 16 is automatically generated, and the creation of the dump output JCL can be facilitated.

When the setting of the various parameters is completed in this way, the dump program generation unit 2 reads the file layout definition information 11 and the copy phrase 12 sequentially, and reads them in the dump program skeleton source 13.
The dump program 16 representing the output process of each data item is automatically described by applying the basic process definition statement (step S5).

At this time, the dump program generation unit 2
The program is described so as not to output the basic items in the lower hierarchy than the group item set in step S4. At that time, the number of digits for the group item is calculated and the number of digits is displayed. If the number of repetitions is specified for a certain data item by the file layout definition information 11, the program is described so as to add an ascending number to the data item and set an output item.
In the conventional list DUMP tool, since repeated data items are expanded and output as data values inside,
Although the number of repetitions is limited, according to the present embodiment, the number of repetitions is not limited.

In this way, the dump program generator 2
The dump program 16 generated by the above becomes an executable dump program module by compiling the source code. In the present embodiment, such an automatic generation process of the dump program 16 is performed in advance for each of various data files and stored in the storage unit 4. The storage unit 4 may store the source program of the dump program 16 or a module after compilation.

The program execution unit 3 executes the dump program 16 stored in the storage unit 4, edits the data file 17 to be dumped in data item units, and outputs it as a dump list 18 which is easy to see. At this time, the conventional list DUMP tool can execute the dump processing only in the JCL, but according to the present embodiment, the screen display is performed using the command procedure (a method of interactively outputting the screen by time sharing). You can also.

FIG. 7 is a diagram showing an example of a file dump process. FIG. 7 (a) shows an example of a dump process using JCL, and FIG. 7 (b) shows an example of a dump process using a command procedure. Is shown. In the example of the command procedure shown in FIG. 7B, the data items can be replaced in correspondence with the screen (underlined portion and the like).

FIG. 8 is a flowchart showing the operation of the program execution unit 3. In FIG. 8, first, the storage unit 4
The user selects the dump program 16 corresponding to the data file 17 to be dumped from the various dump programs 16 stored in the program (step S11).
At this time, by confirming the program ID which is the data file identification information attached to the dump program 16, it is possible to easily grasp which dump program 16 should be selected corresponding to the data file 17 to be dumped. It is possible.

Next, the data file 17 to be dumped is input to the program execution unit 3 (step S12). In the present embodiment, the file organization and record length (total number of digits of all data items described in the copy clause 12)
Is already set when the dump program 16 corresponding to the dump target data file 17 is automatically generated.
In JCL, a file can be opened (input start declaration) and input processing can be performed only by specifying an input file name. That is, in the conventional list DUMP tool,
Each time it was necessary to specify the layout definition of the data file, change the file length, etc.
In the present embodiment, such a measure can be eliminated.

Next, by outputting the name, attribute type, number of digits, and the value of each data item for each record of the file, a dump list 18 in which the data files 17 to be dumped are classified for each data item is output ( Step S13). At this time, for data items having a decimal point, a display including the decimal point is performed. Conventional list DU
In the MP tool, such a display option could not be included for each data item, but in the present embodiment, such a display option is realized by the automatic generation function of the dump program 16.

FIG. 9 shows a dump program 16 automatically generated from the file layout definition information 11 shown in FIG.
FIG. 6 is a diagram showing an output image of a dump list 18 generated from the input dump target data file 17. Since the dump list 18 is sorted and arranged for each data item, the dump output result is very easy to see.

As described in detail above, according to the first embodiment, a different dump program 16 is automatically generated for each of various data files in advance and stored in the storage unit 4. Then, at the time of subsequent verification execution, dump processing is performed by selectively using the dump program 16 corresponding to the dump target data file 17. At this time, the selected dump program 16 related to automatic generation is
The dump program 16 is a dedicated program for the data file 17 to be dumped, and the dump program 16 itself holds all necessary information such as file organization definition and parameters.

Therefore, when the verifier performs the dump processing, the dump processing can be executed by designating the necessary dump target data file 17 without inputting the definition information and parameters of the file organization each time. As a result, the program verification work and, consequently, the productivity of program development can be improved. Further, even a person who does not have specialized knowledge of file organization or the like can easily perform program verification by dump processing without being particularly conscious of it.

The dump list 18 to be output is sorted and arranged for each data item, so that a dump output result that is easy to see at a glance can be obtained. This makes it difficult for the verifier to mistakenly view the dump list, and enables accurate program verification. Therefore, the quality of the program verification work and, consequently, the program development quality can be improved.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 10 is a block diagram illustrating a functional configuration of the file dump output device according to the second embodiment. Note that in FIG. 10, components denoted by the same reference numerals as those illustrated in FIG. 1 have the same functions, and redundant description is omitted here.

As shown in FIG. 10, the file dump output device 10 according to the second embodiment includes a dump program generation unit 2 and a dump program generation program 15 shown in FIG.
In place of the above, a dump program generating unit 5 and a dump program generating program 21 are provided, and a manual correction executing unit 6 corresponding to a program changing unit of the present invention is further provided. This manual correction execution unit 6 is also actually constituted by a CPU or MPU of a computer.
This is realized by the operation of the dump program generation program 21 stored in an AM, a ROM, a hard disk, or the like.

The dump program generation program 21
This is a program for causing the computer to function as the manual correction execution unit 6 in addition to the dump program generation unit 5. The dump program generation unit 5 has substantially the same function as the dump program generation unit 2 shown in FIG. 1, but stores a multi-layout data file using a plurality of copy phrases (a plurality of data). It has a function of automatically generating a dump program 16 for accurately dumping each data item.

That is, the dump program generation unit 5
In the operation shown in FIG. 6, when generating the dump program 16 in step S5, the file layout definition information 11 corresponding to a plurality of copy phrases is continuously input, and all the data included in each definition information are input. Extract items. That is, unlike the conventional list DUMP tool, not only the data items included in the first copy phrase but also all the data items included in a plurality of copy phrases are extracted.

In the conventional list DUMP tool, the contents of all data items are output for a multi-layout data file using a plurality of copy phrases because the position of the data items cannot be determined for the second and subsequent data. Could not be realized. On the other hand, according to the present embodiment, since the output is made by actually using the data item of the copy phrase, there is no need to confirm the position of the data item.
It is possible to extract all data items included in a plurality of copy phrases.

The dump program generation unit 5 further performs the same processing as in the first embodiment using the data items extracted for each copy phrase, and stores a dump list 18 divided into data item units for each copy phrase. Generate automatically. At this time, considering that the same data item name is used in the same data file by using multiple copy clauses, determine the level number of the data item and identify it for each data item. Automatically generate information for

However, the dump program 16 automatically generated at this time does not support outputting a data item with a different layout of a copy phrase according to the value of the data item. However, in the present embodiment, the automatically generated dump program 16 can be manually corrected by the manual correction execution unit 6. In this case, since all the data items included in each copy phrase have been extracted as described above, a conditional branch is performed in accordance with a certain value of the data item, and a dump is performed so that only the data items of the necessary copy phrase are output. The program 16 can be easily customized.

That is, a copy phrase in the data file is identified according to a data value such as a level number or a copy phrase name, and each record is classified into correct data item units according to a layout corresponding to the identified copy phrase. The dump program 16 can be easily customized to output the dump list 18.

Further, the use of the manual correction executing section 6 can cope with the output of the redefined item in which the handling of the item is changed according to the value of the data item. For example, the dump program 1 generated by the dump program generator 5
6 is a program that outputs a dump list 18 as shown in FIG. 11 when the data file 17 to be dumped is dumped.

This program, as shown in FIG. 12A, describes a process of sequentially outputting data items in the order described in the file layout definition information 11. Therefore, it is easy to add a control procedure such as a conditional branch for each output statement of one item. For example, as shown in FIG. 12B, when the deviation value is less than 60, it is possible to modify so that only the first account number (001) among the five account numbers is output. When the dump target data file 17 is dumped using the dump program 16 modified in this way, the dump list 18
Is as shown in FIG.

In the conventional list DUMP tool, dump processing is performed according to a fixed dump program irrespective of the contents of the data file. Therefore, it is only possible to output items in a predetermined method. It was impossible to incorporate them. In addition, since only the function of inputting the data file to be dumped and outputting the dump list is provided, the dump output processing is performed at once by the internal processing of the fixed dump program, and the contents of the dump program are confirmed and manually corrected. I couldn't do anything at all.

On the other hand, in the present embodiment, the dump program 16 is automatically generated based on a skeleton source of a general programming language (for example, COBOL), and is temporarily stored in the storage unit 4. The contents of the item output process of the program 16 can be confirmed.

As described above, according to the present invention, the result of dump processing is converted into data item units based on file definition information representing the organization of data files and a basic program describing the basic processing of a dump program. Since a dump program for outputting the data in a divided manner is generated and stored in a recording medium, a data file is applied to the dump program stored in the recording medium to execute the dump processing. A dump program matching the file organization can be generated and stored in advance. Therefore, when the verifier performs the dump process, the dump process can be executed only by specifying the data file to be dumped, without having to input the definition information of the file organization each time. As a result, the productivity of program development can be improved. Further, even a person who does not have the specialized knowledge of the definition of the file organization or the like can easily perform the dump processing without being particularly conscious of the fact. Further, since the output dump processing results are sorted and arranged for each data item, it is possible to obtain a dump output result that is easy to see at a glance. This makes it difficult for the verifier to mistakenly view the dump list, and enables accurate program verification. Therefore, the quality of the program verification work and, consequently, the program development quality can be improved.

According to another feature of the present invention, the identification information of the data file corresponding to the file definition information used for generating the dump program is set as a parameter. When stored, the dump program corresponding to the data file to be dumped can be easily determined based on the identification information. Therefore, the verifier can perform a dump process by selecting an appropriate dump program without knowing the organization of the data file to be dumped at all.

According to another feature of the present invention, the data file type is set as a parameter, and the dump program is generated using the basic program corresponding to the set type. A dump program can be generated and stored in advance according to the file organization for each type. Therefore, when a verifier performs a dump process, the dump process can be executed only by specifying a data file to be dumped, without setting a file type parameter each time.
As a result, the productivity of program development can be improved.

According to another feature of the present invention, a data item in a data file and the number of digits thereof are set as parameters, and the set data items are collectively output by the number of digits into one item. Since the dump program is generated, a dump process in which a plurality of data items are collectively output as one group item can be easily realized by setting parameters.

According to another feature of the present invention, when a data file has a plurality of data items, all data items are extracted, and the data file is dumped by dividing the extracted data item units. A dump program to output the processing result is generated. By adding controls such as conditional branching, the dump program is modified to output a dump using appropriate data items for each case. be able to. Therefore, even in a so-called multi-layout data file,
It is possible to output a dump list that is easy to read by accurately editing all layouts in data item units. Since the correction in this case can be made relatively easily, it is possible to improve the program verification work and, consequently, the productivity and quality of program development.
