Description

  The present invention relates to a program management ledger creation system, and in particular, upon the transfer of software assets accompanying the transfer of a computer system, the contents of all programs to be transferred are analyzed, and a new one integrated based on the result of the analysis. The present invention relates to a program management ledger creation system for creating a program management ledger.

  When transferring or replacing computer systems, it is necessary to organize the program assets that have been stored so far and create a new program management ledger. In some cases, a document regarding an updated part of a program (for example, an updated part including a corrected part due to a failure or an enhanced part of a function) does not remain. There are also cases where programs that have been abolished still remain in the ledger.

  In order to carry out the task of creating a unified program management ledger by managing program assets in a batch, from among a huge number of programs (thousands or more in some cases) stored so far, It is necessary to extract the currently used programs and manage them. However, such operations are difficult to perform manually under the circumstances described above. If it is carried out manually, there is a fear that man-hours may increase and a process may be omitted.

In addition, there is a possibility that an error occurs in the link between the program and the JCL (job control language of the operating system) used by the program, and the link between the program and the subroutine program called by the program.
In order to solve such a problem, for example, in Patent Document 1, a catch-up processing program and a migration program management ledger are linked, and after execution of the catch-up processing program, the corresponding program in the program management ledger after the migration is automatically performed. There has been proposed a program management ledger creation system that maintains a name correction date and automatically outputs a list of programs that need to be retested, thereby eliminating test omissions.
JP 2003-44319 A

However, in the conventional program management ledger creation system described in the background art, for example, in the case of the technique disclosed in Patent Document 1, the subroutine program and JCL used by the program are It is not possible to manage it in association with the program. For this reason, there is a problem that there is a great risk of leakage during program migration during system migration.
That is, as described above, omission of registration to the program management ledger occurs in the data of the program that is still used, the link between the program and the JCL used for the program, and the link between the program and the subroutine program called by the program There was a risk of errors.

  The present invention has been made in view of the above-described conventional problems. By analyzing the contents of a currently used program including a subroutine program and JCL related to the program, the program can be transferred. It is an object of the present invention to provide a program management ledger creation system capable of performing update 1 of the program management ledger without causing omission.

  In order to solve the above problems, a program management ledger creation system according to the present invention is a program management ledger creation system for creating a management ledger for one or more programs used in a computer system, the computer system Based on the collected attribute information and the results of the analysis, means for collecting attribute information, means for analyzing the collected attribute information, and each of the one or more programs used in And a means for creating a program management ledger for managing each of the one or more programs, and a means for storing the program management ledger in a program management ledger database. A system is provided.

  In addition, the program management ledger creation system may use the program management for one or more JCL data managed separately from the program, for which a link with any of the plurality of programs exists. A JCL name of the JCL data in which the link exists is set in an item indicating a use JCL of the program data corresponding to the linked program in the program management ledger stored in the ledger database.

In the program management ledger creation system, the attribute information includes at least a program name, a language name, a creator name, a program type, a subroutine call instruction word, and a step number.
In the program management ledger creation system, the program type distinguishes whether or not the program is a subroutine.
The program management ledger creation system further comprises means for searching the program management ledger stored in the program management ledger database based on a designated search condition.

In the program management ledger creation system, the search condition specifies processing at the time of searching, and at least an item for displaying a list of programs as a selection item for specifying processing at the time of searching, JCL And a program name linked to the JCL, and an item for displaying the program and a subroutine called by the program in correspondence with each other.
In addition, when an item for displaying a list of programs is selected, the program management ledger creation system displays a program data display screen corresponding to the searched program on the program currently used by the program. A display item indicating whether or not there is provided.

In the program management ledger creation system, the determination method necessary for distinguishing whether or not the program is a currently used program is an item indicating the JCL of the program data corresponding to the program. This is done by verifying whether or not the numerical value 0 is set. When the numerical value 0 is set in the item indicating the used JCL, it is determined that the program is not currently used. When the numerical value 0 is not set in the item indicating the use JCL, it is determined that the program is still used.
In the program management ledger creation system, the search condition is input via a display screen on which a designation input on a display device is possible.
Further, in the program management ledger creation system, the display screen for inputting the search condition and the display screen for displaying the search result of the program management ledger are the same display screen.

As described above, according to the program management ledger creation system of the present invention, since the attribute information is analyzed for all the programs that are currently in use, the leakage including the JCL and subroutine programs related to the program is also included. Therefore, the program management ledger can be created accurately, and the reliability and practicality of the program management ledger are greatly improved.
In addition, a search means for searching the created program management ledger and a display means for displaying the search results are provided, and the processing contents at the time of the search can be selected and specified, so it is registered in the program management ledger. Among the software assets that have been made, there is an effect that necessary items can be quickly browsed.
Further, since it is verified whether the JCL name is actually set for the item indicating the used JCL of the searched program data, it is possible to distinguish whether the program is currently used. As well as becoming clear, there is an effect that the information about the program can be grasped accurately and quickly.

FIG. 2 is a flowchart showing a processing operation at the time of program migration in the program data extraction / editing processing unit 105 of the program management ledger creation system according to the embodiment of the present invention.
The processing operation at the time of program migration in the program data extraction / editing processing unit 105 will be described below with reference to FIG. 1 and the flowchart shown in FIG.

First, the counters m and n used in this process and the program management ledger (here, the internal memory of the host computer 101) are cleared (step S201).
Next, one piece of program data (hereinafter, simply referred to as “data”) of the program library (a library storing the program before migration) stored in the program library DB 103 is read (step S202).
Next, it is determined whether or not the data in the program library is over. If the data is over, the process is terminated. If the data is not over, the process proceeds to step S204 (step S203).

In step S204, it is determined whether or not the data of the program (one line) in the program library is over. If the data is over, the process proceeds to step S218. If the data is not over, the process proceeds to step S205. .
In step S218, the value of the counter m is set in the item of the number of steps in the program management ledger. Thereafter, in step S219, the program management ledger is output to the program management ledger DB 107, and the process returns to step S201.

In step S205, it is determined whether or not there is a character string indicating a program name in the data. If there is a character string indicating a program name in the data, the process proceeds to step S213, and the program name is included in the data. If there is no character string that signifies, the process proceeds to step S206.
In step S213, the character string representing the program name is set in the program name item of the program management ledger, and then the process proceeds to step S206.
Note that the above-mentioned character string meaning the program name is arbitrarily set by the system designer in advance, and “PGM” here corresponds to the character string meaning the program name.

In step S206, it is determined whether or not there is a character string meaning a language name in the data. If there is a character string meaning a language name in the data, the process proceeds to step S214, and the language name is included in the data. If there is no character string that signifies, the process proceeds to step S207.
In step S214, the character string indicating the language name is set in the language name item of the program management ledger, and then the process proceeds to step S207.
Note that the above-mentioned character string meaning the language name is arbitrarily set by the system designer in advance. Here, "COBOL" or "PL / 1" is the character string meaning this language name. Applicable.

In step 207, it is determined whether or not there is a character string meaning the creator name in the data. If there is a character string meaning the creator name in the data, the process moves to step S215, and the data contains If there is no character string indicating the creator name, the process proceeds to step S208.
In step S215, the character string indicating the creator name is set in the creator name item of the program management ledger, and then the process proceeds to step S208.
In step 207, as a specific method for determining whether or not there is a character string meaning the creator name in the data, for example, the creator name is written in a Chinese character string. In addition, since there is a low possibility that a kanji character string is used in other matters, it is possible to determine whether or not there is a kanji character string in the data.

In step S208, it is determined whether or not there is a character string that means a subroutine in the data. If there is a character string that means a subroutine in the data, the process proceeds to step S210, which means a subroutine in the data. If there is no character string, the process proceeds to step S209.
In step S209, the character string “program” is set in the program type item of the program management ledger, and then the process proceeds to step S211.
In step S210, the character string “subroutine” is set in the program type item of the program management ledger, and then the process proceeds to step S211.
In step S208, as a specific method for determining whether or not there is a character string that means a subroutine in the data, for example, the creation rule for the name of the created subroutine is "" SUB "+3 If it is "digit number", "SUB" becomes a character string meaning a subroutine. In general, there is a program development standard unique to each developer such as a company for generating a subroutine name. Therefore, a system designer can determine a determination rule based on a rule in the company.

In step S211, it is determined whether or not there is an instruction to call a subroutine in the data. If there is an instruction to call a subroutine in the data, the process proceeds to step S216, and after the instruction to call a subroutine in the data. If not, the process proceeds to step S212.
As a specific determination method for determining whether or not there is an instruction word for calling a subroutine in step S211, for example, a character string in the data read from the program library is searched, and the language name of the read data is determined. If COBOL or PL / 1, the presence / absence of the character string “CALL” is determined, and if it is MASP, the presence / absence of the character string “SUB” is determined.

In step S216, the value of the counter n is increased by +1. In the next step S217, the subroutine name described immediately after the instruction word for calling the subroutine is changed to the subroutine name (n) used in the program management ledger. Then, the process proceeds to step S212.
In step S212, the value of the counter m is increased by +1, and the process returns to step S202.

FIG. 3 is a flowchart showing a processing operation at the time of program migration in the JCL data extraction / edit processing unit 106 of the program management ledger creation system according to the embodiment of the present invention.
The processing operation at the time of program migration in the JCL data extraction / edit processing unit 106 will be described below with reference to FIG. 1 and the flowchart shown in FIG.

First, one piece of JCL data (hereinafter simply referred to as “data”) of a JCL library (a library storing JCL before migration) stored in the JCL library DB 104 is read (step S301).
Next, it is determined whether or not the data in the JCL library is over. If the data is over, the process is terminated. If the data is not over, the process proceeds to step S303 (step S302).

In step S303, it is determined whether or not there is a character string that represents the JCL name in the data. If there is a character string that represents the JCL name, the JCL name is obtained in step S305, and then the process proceeds to step S304. If there is no character string indicating the JCL name, the process immediately proceeds to step S304.
As a method for determining whether or not there is a character string that means a JCL name in step S303, for example, when the creation rule for the created JCL name is "" JCL "+ three-digit serial number" The character string “JCL” indicates the presence of a character string meaning the JCL name. This determination method is similar to the above-described determination method for determining whether or not there is a character string indicating a subroutine in the processing shown in FIG. Although it is only an example, generally, a system designer can determine this determination rule based on a rule in the company. Here, in order to make it easy to understand, it is determined that the character string “JCL” exists.

In step S304, it is determined whether or not there is a character string that means a program name in the data. If there is a character string that means a program name, the process proceeds to step S306, and there is no character string that means a program name. Return to step S301.
Note that the method for determining whether or not there is a character string that represents the program name is the same as the description of the processing shown in FIG.

  In step S306, the program management ledger DB 107 is searched using a character string representing the program name as a key, and then in step S307, the “use of program management ledger (created on the internal memory of the host computer 101) is used. After setting the JCL name in the item of “JCL name” (however, after setting the numerical value 0 when there is no JCL name), this program management ledger is output to the program management ledger DB 107, and then the process returns to step S301.

FIG. 4 is an explanatory diagram for explaining an example of display contents of the program management ledger DB search processing screen 109 of the program management ledger creation system according to the embodiment of the present invention.

In the search condition illustrated in FIG. 4, “Program List” is selected, so the program management ledger DB 107 is searched under the condition.

Next, it is determined whether or not the “use JCL name” item is 0 for the data (ie, program) obtained by searching the program management ledger DB 107, and the “use JCL name” item is 0. In step S404, the process proceeds to step 406. If the item “used JCL name” is not 0, the process proceeds to step S405 (step S404).
In step S405, the character string “in operation” is set in the “operation status” column of the display screen area, and the flow advances to step S407.
In step S406, the character string “not operating” is set in the “operation status” column of the display screen area, and the process proceeds to step S407.
In step S407, the contents of the display screen area are displayed on the display screen 109, and the process ends.
