Description

METHOD AND COMPUTER PROGRAM STORED IN COMPUTER READABLE MEDIUM FOR CONVERTING SORT SCRIPT TO REUSE JCL IN DIFFERENT ENCODING ENVIRONMENT BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a sort script conversion method for reusing JCL in an environment where encoding is different and a computer program stored in a computer-readable medium. More particularly, the present invention relates to a computer program for encoding a sort script, A method for analyzing information for script conversion according to a difference, a method for providing sort script conversion information based on analyzed information, and a computer program for performing such a function.

The mainframe system was introduced in the 1960s and 1970s by governments, financial institutions, and large corporations to handle various data needed for business activities. The mainframe system refers to a large-scale general-purpose computer that performs various tasks by adopting a centralized method of connecting a plurality of terminals to one computer. For example, IBM's System / 360. The mainframe system has been around for over 30 years, leading the industry in the computing industry. However, in the late 1980s, a distributed environment in open systems such as Unix platforms emerged and an open system to reduce system operating costs As the downsizing wind blew, the position of the mainframe system shook tremendously.

Unlike mainframe systems, an open system refers to a system that is open to the interface and does not rely on the closed technologies and programs of a specific vendor, and is capable of interconnection or portability with other types of computers. For example, UNIX do. Recently, there has been an attempt to completely rebuild mainframe systems with open systems, but this is a risky task, costly, and labor-intensive.

A rehosting solution was presented as a new alternative. Rehosting is a sophisticated IT system implementation strategy that enables an IT system, which is built in mainframe system environment, to be reused as an open environment without application redevelopment. Rehosting can be expected to have many positive effects, such as minimizing the initial cost and time burden of redevelopment and minimizing the risk of maximizing the use of existing resources.

Reusing job control languages in environments with different encodings, such as EBCDIC used in mainframe systems and ASCII used in open systems, is a task that requires translation of the sort script. Because of this, sorting order may be different in the main frame and the open environment. Therefore, if the fields used as sort keys are composed of compound fields, it is necessary to study a method of sorting the fields by adaptive encoding separately for each field.

The Job Control Language (JCL) tells the operating system what to do to process the data. JCL consists of a series of JCL statements with a set of rules. The JCL statement tells the operating system what to do, what program to run, what resources the program needs, etc. can do.

The JCL statement can perform the following functions. Pass the job to the operating system. It also presents to the operating system what to do. It requests the operating system to allocate a hardware device for a specific dataset and designates a program to be executed.

A series of jobs submitted by the user to the operating system for execution is called an input Job Stream. The input Job Stream consists of one or more Jobs, and one Job consists of one or more Steps. Each Job can consist of the following JCL statements. For example, a JCL statement may include a 'Job Statement' to indicate the start of a job, one or more 'EXEC Statements' to indicate the beginning of a step, a 'DD Statement' to define a Dataset required to perform a Job Step, Delimiter Statement.

A step is the minimum unit of work that must be performed on the same processor in a system with multiple processors (CPUs). In other words, one step can not be divided into several sub steps and can not be executed in parallel. It is possible to execute in parallel between steps in the same job by advanced system processing techniques. However, depending on the system environment and Job characteristics, whether to perform or not and the degree of parallel execution are determined.

A Job Statement can tell the Operating System the start of a job. A Job Statement can specify information to identify a job and parameters necessary to execute the job. In addition, one Job is terminated when the next Job Statement is found or when a NULL Statement is found.

The EXEC Statement starts with an EXEC Statement that specifies the name of the program to run. One job has one or more job steps. A job step terminates when it encounters the next EXEC Statement, Job Statement, or NULL Statement.

The DD Statement specifies the Dataset (similar to a File on a UNIX server, etc.) required by the program. One Dataset is specified as one DD Statement. Specify the Dataset name to use, the input / output device to be used, the location of the Dataset, the allocation method, and other Dataset characteristics.

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

FIG. 1 is a block diagram illustrating a sort script conversion system for reusing JCL in an environment with different encoding according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, a sort script conversion system according to an embodiment of the present invention may include a main frame system 100, an open system 200, and a sort script conversion apparatus 300.

The mainframe system 100 is an industry term for a large computer created by a large company such as IBM, for example, and is used primarily for computing tasks required by large corporations such as large corporations and financial institutions. Rather than a centralized system.

The open system 200 is an industrial term that refers to a method for designing a link between hardware (H / W) and software (S / W) of different computer manufacturers. The open system 200 can be classified into an operating system, The open system referred to herein is a medium-sized computer equipped with an operating system such as UNIX (Unix) or Linux.

The sort script conversion apparatus 300 divides one or more job steps in a job control language (JCL) of the mainframe system 100 and executes an execution program (Program) , A dataset name (DSN), and a data description (DD). Thereafter, the sort script conversion apparatus 300 acquires a file description (FD) corresponding to the data description from the execution program source corresponding to the execution program, and acquires the first copy book Can be generated. The sort script conversion apparatus 300 compares the generated first copybook with the sort field SORT FIELD included in the work step to determine the validity, and then, based on the result of the determination of the validity, A book can be created and saved. In addition, the sort script conversion apparatus 300 can convert the sort field by referring to the stored second copy book. Accordingly, if the sort script conversion apparatus 300 according to the embodiment of the present invention does not maintain the sort script encoding in the Unix environment as ASCII but maintains the EBCDIC, The conversion can be automated and high speed and accuracy can be secured compared to the conventional method.

The sort script conversion apparatus 300 according to an embodiment of the present invention may be OFMiner. OFMiner parsing and analyzing MaiknFrame's Asset Asset (JCL, JCL Prodedure, Cobol source, copybook, Map, etc.) to DB and making it necessary for data migration or asset analysis And an analysis system for extracting information.

FIG. 2 is a block diagram illustrating an internal structure of a sort script conversion apparatus for reusing JCL in an environment having different encoding according to an embodiment of the present invention. Referring to FIG.

2, a sort script conversion apparatus 300 according to an embodiment of the present invention includes a work step sorting unit 310, an extracting unit 320, a file description obtaining unit 330, a first copybook generating unit 330, A validity determination unit 350, a second copybook generation unit 360, and a sort field conversion unit 370.

The work step sorting unit 310 can distinguish one or more job steps in a job control language (JCL). The job control language may include one or more job steps. Each work step may include at least one of an execution program (Program, PGM), a dataset name (DSN), and a data description (DD).

The extracting unit 320 may extract an execution program (Program, PGM), a dataset name (DSN), and a data description (DD) in a work step. Execution program (Program, PGM) can be checked in EXEC Statement in Job Control Language (JCL). In one embodiment, the execution program may include a COBOL program and a SORT program, but the scope of the present invention is not limited thereto. The dataset name (DSN) can be found in the DD Statement of the job control language. In the mainframe system 100, a dataset may correspond to a file of the open system 200. Dataset name to use in DD Statement, input / output device to use, location of dataset, allocation method and so on can be specified.

The file description acquisition unit 330 may obtain a file description (FD) corresponding to the data description from the execution program source corresponding to the execution program. For example, when the executing program is COBOL, the file description obtaining unit 330 may retrieve the COBOL program source corresponding to the executing program. The COBOL program source may be pre-stored in a database or the like. Thereafter, a file description can be obtained from the retrieved COBOL program source. At this time, the file description to be obtained may include a file description corresponding to the data description. That is, the file description obtaining unit 330 may obtain a file description corresponding to the data description based on the data description.

The first copybook generator 340 may generate a first copy book based on the file description acquired by the file description acquiring unit 330. [ That is, the file description obtaining unit 330 may obtain a layout of data corresponding to the data set name in the file description, and may generate the first copy book using the obtained layout.

The validity determination unit 350 can determine the validity by comparing the first copybook generated by the first copybook generator 340 with the sort field SORT FIELD included in the work step. If the sort field (SORT FIELD) included in the work step corresponds to the first copy book, validity can be recognized.

 The second copybook generation unit 360 can designate or set the first copybook as the second copybook according to the result of the validity determination of the validity determination unit 350. [ The validated second copybook can be a basic data that can be used to check if the sort field included in the job control language is a sort field that can be used in the open system 200 and convert the sort field as necessary.

The sort field conversion unit 370 can convert the sort field included in the job control language with reference to the second copy book. The sort field included in the job control language is not always converted, and the use of the sort field included in the job control language in the open system 200 will require conversion of the sort field only when the same result is not obtained.

3 is a flowchart illustrating a sort script conversion method for reusing JCL in an environment in which encoding is performed according to an embodiment of the present invention.

Referring to FIG. 3, in step S110, the work step sorting unit 310 may classify one or more job steps in a job control language (JCL).

The job control language may include Job Statement, EXEC Statement, and DD Statement. As described above, a Job Statement can inform the Operating System of the start of a job, specify information to identify the Job, and specify the parameters needed to execute the Job. An EXEC Statement starts with an EXEC Statement that specifies the name of the program to be executed, and a Job Step ends when the next EXEC Statement, Job Statement, or NULL Statement is encountered. The DD Statement specifies the dataset the program needs, the dataset name to use, the input / output device to use, the location of the dataset, the allocation method, and other dataset characteristics.

4 illustrates a job control language according to an embodiment of the present invention.

Referring to FIG. 4, the task control language according to an embodiment of the present invention can be divided into four work steps (ST01, ST02, ST03, ST04). Hereinafter, four working steps will be described as an example for the sake of clarity in describing an embodiment of the present invention, but the working steps are not limited thereto. The EXEC Statement and the DD Statement are included in each of the work steps ST01, ST02, ST03 and ST04. In particular, the alignment of the Dataset with the SORT field in the work step (ST02) You can see what is defined.

3, in step S120, the extracting unit 320 extracts an execution program (Program, PGM), a dataset name (DSN), and a data description (DD) from a work step have. It can be confirmed that the execution program (Program, PGM) is COBOL1, the dataset name (DSN) is AAA.BBB, and the data description (DD) is SYSUT1 in the work step ST01 in Fig. You can specify the executable program source using the PGM syntax in the job control language. In this case, there are many file descriptions (FD) defined in the execution program source. In the file description of the execution program, DD (SYSUT1) defined in the data description of the job control language is allocated to the file description in the SELECT syntax of the execution program A data description is required. In other words, you need to know the file description to make a copybook with the data declaration of the corresponding file description.

4, the execution program (Program, PGM) is SORT, the dataset name DSN is AAA.BBB, the sort field SORT FIELDS is SORT FIELDS = (1,2, CH, 5, 4, CH). Where 1 represents LOCATION (position in the SAM file of CONTROL FIELDS), 2 represents LENGTH (length of CONTROL FIELDS), and CH represents DATA FORMAT (DATA TYPE of CONTROL FIELDS). That is, in the data set of AAA.BBB included in the work step ST02, it can be seen that the first byte includes two bytes from character (CH) alignment, and the fifth byte from the fourth byte is character (CH) alignment. If SORT FIELDS = (1,2, CH, 5,4, BI), then the fourth byte from the fifth byte may be a numeric (BI) alignment.

In the same way, in the operation step ST03, the execution program (Program, PGM) is SORT, the Dataset Name (DSN) is CCC.DDD and the SORT FIELDS is SORT FIELDS = (1,2, CH , 3, 4, ZD). The data set of CCC.DDD included in the work step ST03 shows that from the first byte, the two bytes are character (CH) sorting, and the third byte to four bytes are the zone decimal (ZD) have. If SORT FIELDS = (1,2, CH, 3,4, PD), then the fourth byte from the third byte can be a packed decimal (PD) alignment.

A method of extracting an execution program (Program, PGM), a data set name (DSN), and a data description (DD) in the work step is described in detail below. First, when the execution program used in the work step is the sort program (SORT Program), the data set name is extracted in the first work step including the sort program. When EXEC PGM = SORT is confirmed in the work step ST02 of FIG. 4, AAA.BBB, which is the name of the data set to be processed, is extracted. Thereafter, an executable program and a data description are extracted in a second work step including the dataset name. Since the name AAA.BBB of the data set is included in the work step ST01 of FIG. 4, the execution program PGM = COBOL1 and the data description SYSUT1 can be extracted. Further, in the first operation step, a sort field SORT FIELDS corresponding to the dataset name can be extracted. In summary, sort information can be configured in the work step ST02 as shown in [Table 1] below.

DSN = AAA.BBB
COBOL1 of PGM = ST01
DD = SYSUT1 of ST01
SORTFIELD = 1,2, CH, 5,4, CH

In the work step ST03, sort information can be configured as shown in the following [Table 2].

DSN = CCC.DDD
PGM = COBOL2 of ST04
DD = SYSUT2 of ST04
SORTFIELD = 1,2, CH, 3,4, ZD

5 illustrates work steps of an execution program and an execution program source used according to an embodiment of the present invention.

3 to 5, in step S130, the file description obtaining unit 330 may obtain a file description (FD) corresponding to the data description from the execution program source corresponding to the execution program. First, the execution program source (COBOL1.cbl) corresponding to the execution program (COBOL1) can be retrieved from the database, and the file description corresponding to the data description can be extracted from the execution program source. A layout of data corresponding to the dataset name can be obtained from the extracted file description and a first copy book can be created based on the obtained layout. For example, since the execution program is COBOL1 in the work step ST02, the database can be searched to use the execution program source, that is, COBOL1.cbl.

In the job control language, since EXEC PGM in work step ST01 declared COBOL1, it can be seen that the layout of dataset is defined in COBOL1.cbl source with this information. At this time, COBOL1.cbl can declare multiple file descriptions and finds a statement using SYSUT1 in the SELECT statement of COBOL1.cbl because the data description of the data set AAA.BBB is SYSUT1. It can be seen that SYSUT1 DD is allocated to FD1 through the SELECT SYSUT1 TO FD1 syntax. Since there is a layout of data in FD1, the first copybook generator 340 generates, based on this syntax, the first copybook generator 340 based on the file description A first copy book can be created.

FIG. 6 illustrates a method for determining the effectiveness of a first copybook according to an embodiment of the present invention.

Referring to FIG. 3 and FIG. 6, in step S150, the validity determination unit 350 may determine the validity by comparing the first copybook with a sort field included in the work step. The validity determination unit 350 may compare the first copybook with the sort field of the data corresponding to the dataset name to determine whether the first copybook matches or not. As shown in FIG. 6, the first copy book (01 REC 03 REC-A PICX (1) 03 REC-N COMP (1) 03 REC-B PIC 9 (2) 03 REC- SORTFIELD = 1, 2, CH, 5, 4, CH of ST02.

In step S160, the second copybook generator 360 designates the first copybook as the second copybook when the result of the determination of the validity matches the first copybook and the sort field (Sort field) A copy book can be created and stored. Here, the generated second copybook can be used when converting the sort field.

In step S170, the sort field converter 370 can convert the sort field by referring to the second copy book. Mainframe system 100 and open system 200 have different encodings. For example, the mainframe system 100 (e.g., IBM) can use EBCDIC and the open system 200 (e.g., a Unix environment) can use ASCII. However, due to the difference in the encoding method, the sort script in the mainframe system 100 may process a portion requiring a BI alignment in a Unix environment by character alignment. If you do not distinguish between numeric (BI) sorting and character (CH) sorting in a Unix environment, it is impossible for encoding to reuse JCL in other environments.

FIG. 7 illustrates a method of converting a sort field by referring to a second copybook according to an embodiment of the present invention.

7, the sort field converter 370 compares the second copybook with the sort field (SORT FIELDS = (1,2, CH, 5,4, CH)) in the work step ST02. In the sort field of the work step ST02, two bytes from the first byte are defined as character (CH) alignment. However, referring to the second copybook, the actual alignment of the data set AAA.BBB is from the first byte to one byte SORT FIELDS = (1,2, CH, 5, 4, CH) SORT FIELDS = (1,1) if the second byte is a numeric , CH, 2,1, BI, 5,4, CH). When using SORT FIELDS = (1,1, CH, 2,1, BI, 5,4, CH) in the open system 200, the data set AAA.BBB in the open system 200 is changed from the second byte to one The bytes can be numeric (BI) aligned.

Figure 8 shows a block diagram of a computer that is operative to execute a sort script conversion program for reusing JCL in an environment with different encoding according to an embodiment of the present invention.
