Abstract

PURPOSE:To eliminate wasteful job waiting time and batch processing part using time generated by supplying the JCL (job control language) of erroneous description. CONSTITUTION:In a computer system provided with a host computer 9 provided with a batch processing part for executing a batch job described by the JCL, before supplying the JCL 2 to the batch processing part, the grammar of the JCL and the presence of a file appearing in the JCL are inspected in this batch job supplying system 8 and the result is displayed at a terminal display device 10. A user confirms the displayed result and then, selects whether or not the JCL 2 is to be actually supplied to the batch processing part of the host computer 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention inputs a job control language (hereinafter referred to as JCL) describing a batch job into a batch processing section of a host computer so that the batch processing section of the host computer can perform job control. The present invention relates to a computer system for executing a batch job described in a language, and particularly to a batch job input system for inputting JCL into a batch processing unit.

[0002]

2. Description of the Related Art In a conventional computer system for batch processing, if the JCL input method is appropriate, the JCL is input to the batch processing section regardless of the contents of the JCL.

[0003]

In the conventional computer system for batch processing, a job is submitted regardless of the contents of the JCL, and the JCL is interpreted and executed sequentially when the job is executed. Therefore, if the user inputs JCL with incorrect grammar or content without noticing the fact, JC will be used until the report after the job is completed.
You will not notice L's mistake. For this reason, there is a problem in that depending on the job waiting state and the contents of the JCL, unnecessary job end waiting time and batch processing unit (CPU) use time occur.

The object of the present invention is to include JCL containing an error in the description.
It is an object of the present invention to provide a batch job input system that can reduce unnecessary waiting time and use time of the batch processing unit by reducing the input to the batch processing unit.

[0005]

According to the present invention, by inputting a job control language describing a batch job into a batch processing section of a host computer, the batch processing section of the host computer is controlled by the job control language. In a computer system for executing a batch job described in a language, in response to the job control language, the job control language is analyzed, and a lexical check for checking whether the description of the job control language is correct or incorrect・ A parser;
A result processing unit for displaying the inspection result of the lexical / syntactic analysis unit on a display device included in the computer system; and a result processing unit for displaying the result of the job control language in the host computer. A batch job submitting system characterized by causing a user to submit the job control language to the batch processing unit only when the description indicates that it is correct is obtained.

Further, according to the present invention, by inputting a job control language describing a batch job into a batch processing unit of a host computer, the job control language is written in the batch processing unit of the host computer. And a lexical / syntactic analysis unit that analyzes the job control language in response to the job control language and checks whether the description of the job control language is correct or incorrect in a computer system that executes the batch job A file inspection unit for inspecting whether or not a file included in the job control language exists in the batch processing unit; and an inspection result of the lexical / syntactic analysis unit and an inspection result of the file inspection unit to the computer system. A result processing unit for displaying on a display device included therein; and displaying on the display device in the host computer. The batch is characterized by causing the user to submit the job control language to the batch processing unit only when the description of the job control language is correct and indicates the existence of a file. A job submission system is obtained.

That is, in the batch job submission system of the present invention, before submitting the job control language to the batch processing section of the host computer, the grammar of the job control language is checked, and whether a file that appears in the job control language exists. By checking whether or not the result is presented to the user, it is possible to prevent the user from inputting the wrong job control language into the batch processing section.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 shows a computer system including a batch job input system 8 according to an embodiment of the present invention. In FIG. 1, 1 is a terminal input device, 2 is JCL
(Job control language) 3, a lexical / syntactic analysis unit, 4 a file checking unit, 5 a result processing unit, 6 a diagnostic message table, 7 a file name table, 9 a host computer, 10 a terminal display device, respectively. Shows.

In FIG. 1, the user generates JCL 2 and inputs the JCL 2 from the terminal input device 1 into the batch job input system 8. The lexical / syntactic analysis unit 3 checks the grammar of the entered JCL and outputs the result to the diagnostic message table 6. Also, the lexical / syntactic analysis unit 3
Extracts the file name appearing in the JCL and outputs it to the file name table 7. Next, the file inspection unit 4 reads the file name from the file name table 7,
Check the existence of the file and output the result to the diagnostic message table. Finally, the result processing unit 5 reads the diagnostic message table 6, edits it, and outputs it to the terminal display device 10. After confirming this message, the user uses the terminal input device 1 to instruct whether or not to insert the JCL into the batch processing unit (not shown) in the host computer 9.

More specifically, the file inspection unit 4 stores in advance a file name which can be processed by the batch processing unit of the host computer 9, and stores the file name read from the file name table 7. Check if the file exists by matching the first name.

[0012]

As described above, according to the present invention, the job control language can be input after the user confirms the grammar of the job control language and the existence of the file. It is possible to reduce the amount of input to the host computer batch processing unit and reduce unnecessary waiting time and use time of the host computer batch processing unit.
