Abstract

PURPOSE:To reexecute a job without inputting the job again, by allowing JCL (job control statement) or SYSIN (system input) data to be edited when a desired execution result is not obtained with regard to the job in a queue for output. CONSTITUTION:A display editing processing part 300 displays JCL data 6, SYSIN data 7, and SYSOUT (system output) data 10 on the job in a queue for output under the control of an output control part 11 on a terminal 13 in response to a request from the terminal 13. A reexecution specification processing part 21 specifies the reexecution of the job in the queue for output by an indication from the terminal 13. A reinterpretation processing part 22 deletes a control table generated by an interpretation processing part 4 before with regard to the JCL data 6 modified by the display editing processing part and interprets new JCL data 6 to generate a control table of the interpretation result.

Description

DETAILED DESCRIPTION OF THE INVENTION 1 (1) Technical Field of the Invention The present invention relates to a job processing method, and particularly to a data processing system that is required by referring to execution results when a job submitted to a data processing system is executed and is waiting for output. A job processing method that makes it possible to change the job control statement or system input data according to the situation, and re-execute the job without submitting the job again. (2) Conventional technology and problems Figure 1 shows An example of a conventional job processing method is shown. In the figure, 1 is a card reader, 2 is an input processing unit, 3 is a spool fist data set, 4 is an interpretation processing unit, and 5 is a job control table (JCT
), 6 is job control statement (JCL) data, 7 is system input (sysIN) data, 8.8' is a control table, 9 is execution processing section, 10 is system output (5YSOUT) data, 11 is output control section, 12 is a terminal display unit, 13 is a display terminal, 14 is an output processing unit, 15 is a line printer, 16 is a magnetic tape device, 17-i to 17-3
represents a direct access device such as a magnetic disk device.

In FIG. 1, an input processing unit 2 reads a job control statement (JCL) and 5YSIN data from, for example, a card reader 1, recognizes a job input into the system, and outputs a job deck consisting of JCL and 5YSIN data to a direct access device. The job is spooled to the spool threat data set 3 of 17-1, and the job is registered.

The interpretation processing unit 4 reads the JCL and 5YSIN data for the registered job from the spool dataset 3, interprets the JCL, and creates control tables 8 and 8 of the interpretation results.
′ etc. Also, JC is connected to the direct access device 17-2.
The L and 5YSIN data are separated and stored as JCL data 6 and 5YSIN data 7, respectively, and directly or indirectly pointed to from the job control table 5 created in advance.

The execution processing unit 9 executes the control table 8.8 created by the interpretation processing unit 4.
', etc., and calls the user program specified by the JCL to execute the job. At this time, the system output data requested to be written by the user program etc. is sent to the direct access device 17-3 via 5Y.
The SOUT data is spooled as 1°, and is pointed to from the job control table 5, for example. Once execution is complete, the job is placed in an output queue.

The output control unit 11 outputs 5YS for jobs waiting to be output.
Scheduling is performed for the output of OUT data 10. For example, by specifying bold in advance, the user can suspend output until the hold is released. 8Y of the job waiting for output on the terminal display unit 12
When a request to display the SOUT data 1o is made from the terminal 13, the terminal display section 6-12 uses the pointer from the job control table 5 to display 5YS.
The OUT data 10 is searched and its contents are displayed on the terminal 13. Furthermore, when a request to delete the 5YSOUT data 10 is made from the terminal 13, the terminal display unit 12 responds to the C edit request to delete the 5YSOUT data 10 without outputting it to the destination specified by the JCL (~ Part of the data 10 is deleted or updated, new edited data is written to the direct access device 17-3, and the pointer from the job control table 5 is replaced.

The output processing unit 14 is activated by the output control unit 11, and
If YSOUT data 10 is Fpu, line printer 15
The cutting edge is output to a designated cutting edge, such as a magnetic tape device 16 or the like. When the output of one 5YSOUT data is completed, output completion is displayed on the control table. The output control unit 11 checks the control table and deletes the job when all 5 YSOUT data 10 of the job have been output.

As described above, the input, execution, and output of a job are processed, and the user can cause the data processing device to execute the desired process. Although it is possible to display the 5YSOUT data 1o, which is the output of the job, on the terminal by the unit 12 and view the execution results of the job, or delete it in units of pages or datasets, if the execution results are not normal, the user If necessary, use JCL or 5Y.
Edit/correct the SIN data and try card reader 1 again.
Jobs had to be resubmitted to the system from other large sword devices. Head over to JCL-? 5YSIN
In practice, situations such as incorrect execution results due to errors in part of the data can often occur.
However, not only is it extremely troublesome to resubmit a job, but even though the JCL etc. are often exactly the same as before, all input and reinterpretation is required, which takes a lot of time. The problem was that the target loss was large. 4 (3) Purpose of the Invention The present invention aims to solve the above-mentioned problems.
Alternatively, the purpose is to enable editing of SYS engineering data and re-execution of the job without having to re-submit it.

(4) Structure of the Invention Therefore, the present invention provides not only functions for displaying and editing 5YSOUT data on the terminal display unit, but also functions for displaying and editing JCL and 5YSOUT data.
The system also focuses on providing display/editing functions for N data, and making use of JCL data, 5YSIN data, and control tables created by interpreting JCL that have already been input into the system. That is, the job processing method of the present invention includes at least an input processing section that reads job control statements and system input data, an interpretation processing section that interprets the input job control statements, and a job execution according to the interpretation result of the interpretation processing section. an execution processing unit that controls the output of system output data of job execution results; an output processing unit that outputs the system output data; In a job processing method that includes a terminal display unit that processes display requests or editing requests, and processes job input, execution, and output, the terminal display unit includes at least a terminal that displays job control statements or system input data related to the job. A display editing processing unit that processes a display request or an editing request from a computer, and a re-execution specification processing unit that accepts a re-execution specification for the job, and the job control statement is changed by the display editing processing unit. The present invention is characterized in that it includes a re-interpretation processing section that sometimes interprets a new job control statement, and re-executes the job in response to a re-execution designation to the re-execution designation processing section. Embodiments will be described below with reference to the drawings.

(5) Embodiment of the invention FIG. 2 shows the configuration of an embodiment of the present invention, FIG. 3 is an explanatory diagram of the processing of the terminal display section according to the present invention, and FIG. 4 shows the processing of the reinterpretation processing section according to the present invention. No explanatory drawings are shown, and in the 0 figures, symbols 1 to 17
1 corresponds to FIG. 1, 207- represents a display editing processing section, 21 represents a re-execution designation processing section, and 22 represents a re-interpretation processing section.

In FIG. 2, the input processing section 2, the interpretation processing section 4, the execution processing section 9, and the output processing section 14 are the same as those of the conventional system, and are the same as described using FIG. 1, so their explanation will be omitted. The terminal display unit 12 is particularly provided with a display editing processing unit 20 and a re-execution designation processing unit 21.

The display editing processing unit 20 generates JCL data 6.5YSI regarding the output waiting job under the control of the output control unit 11.
The N data 7 and the 5YSOUT data 10 are displayed on the terminal 13 or edited or deleted in response to a request from the display terminal 13.

That is, the conventional terminal display section 12 displays 5YSOUT data 1
Previously, only the operation for J0 was possible from the terminal 13, but in the present invention,
Regarding CL data 6 and 5YSIN data 7, for example, by inputting a command from the terminal 13, 5YSOUT
Like data 10, it can be operated.

8- The re-execution designation processing unit 21, based on the instruction from the terminal 13,
This specifies re-execution of a job that is waiting for output. In addition, changes to JCL data 6 or 5Y
When the SIN data 7 is edited by the display editing processing unit 20, re-execution may be automatically specified without an instruction from the terminal 13. The re-execution designation is notified to the output control unit 11 by turning on a re-execution designation flag provided in a control table used as an interface between each processing unit. At this time, the output control section 11 is configured to activate the reinterpretation processing section 22 when there is a change in the JCL data 6, and to activate the execution processing section 9 when there is no change in the JCL data 6. Note that the output control unit 11 simply requeues the job in the job queue, and then sends the job to the reinterpretation processing unit 22 or the execution processing unit 9.
However, regarding the JCL data 6 changed by the display editing processing section 20, the control table reinterpretation processing section 22 deletes the control table previously created by the interpretation processing section 4, interprets the new JCL data 6, and interprets the new JCL data 6. It creates a control table of the results. When the processing of the reinterpretation processing section 22 is completed, the execution processing section 9 is called and the execution is re-executed based on the new interpretation result.

Next, the processing of the terminal display section 12 will be explained with reference to FIG. For the terminal display section 12, the display terminal 1
When a processing command for a job waiting for output is input from 3, the terminal display section 12 starts the display editing processing section 20.0 The display editing processing section 20 first performs the processing 30 shown in FIG. It is determined whether display of data 10 or JCL data 6 is requested. If you are requesting to display
In process 31, the corresponding data is obtained from the pointer of the job control table 5, and its contents are transferred to the terminal 13 and displayed.Next, in process 32, it is determined whether there is a request to delete the 5YSOUT data 10. If there is a deletion request, all or a designated part of the SYS OUT data 10 is deleted in step 33, and the output by the output processing unit 14 is omitted.

Next, in process 34, it is determined whether or not it is a request to change the JCL data 6. If it is a change request, update/delete/update/delete the JCL data 6 pointed from the job control table 5.
Processing such as addition is executed by process 35 to create a new JC.
Write the L data 6 to the direct access device 17-2,
Replace the pointer from job control table 5. moreover,
Turn on the JCL change display flag provided in the control table.

Also, by processing 36, 5YSIN data 7 or 5Y
It is determined whether there is a request to edit the SOUT data 10. If there is an editing request, the specified 5YSIN data 7 or 5YSOUT data 1 is
0 editing process is performed. Here, 5YSOUT data 10
The editing process for 5YSIN is the same as before, but 5YSIN
The editing process of data 7 is also specified as 5YSOUT data 1.
Processed in the same way as editing 0.

Processes 30 to 37 are repeated every time a command is input from the terminal 13, and the JCL, a plurality of 11-8YSIN data, and 5YSOUT data are referenced and edited.

Next, the re-execution designation processing section 21 is activated, and first, in step 38, the re-execution designation processing section 21 determines whether the command requests re-execution of the job. If re-execution is requested, the re-execution designation flag in the interface control table is turned on in step 39.

The output control unit 11 refers to this re-execution designation flag, and if it is off, it starts the output processing unit 14 in response to a schedule trigger as before.0 If the re-run designation flag is on, it starts J
Determine the CL change display flag and start the reinterpretation processing unit 22 when the nuclear flag is on, and the execution processing unit 9 when it is off.The reinterpretation processing unit 22 performs the processing as shown in FIG. do.

First, in process 40, the control table that is the result of the original JCL interpretation is deleted. Next, in process 41, the new JCL data 6 created by the display editing processing section 20 is interpreted and a new control table 8.8' is re-created. Then, after resetting the JCL change display flag and re-execution designation flag in process 42, control is transferred to the execution processing unit 9. The execution processing unit 9 will execute the job again.

(6) As described in detail, according to the present invention, when the desired result is not obtained by referring to the job execution result, the JCL data or 5YSIN data is changed as necessary, and the job is executed. It can be re-executed without re-submitting. Junior Q
This not only improves operability, but also allows job registration, spool space allocation, JCL,! : 5YSIN
Input processing and interpretation processing such as data separation can be omitted, and time loss associated with redoing can be significantly reduced. Even in the case of interactive remote batch jobs using TSS, it is possible to eliminate the overhead of, for example, the SUBMIT command used to request batch processing of a job to the center, which is highly effective.
