The key portion 82 is composed of a program ID 86, which matches the program ID used in the business process. The data portion 84 is provided with a storage number prediction formula 88. The storage count prediction formula is prepared as a formula for calculating the file capacities of the database and the general file from the file record count and the record length.

An outline of the computer processing work of the present invention in FIG. 4 will be described below. When the business process is started after receiving the input file data from the front system, the process preparation unit 22 operates first, and the pre-check processing unit 3 thereof is operated.
According to 0, a real file status check is performed to determine whether the business process can be executed.

In this actual file status check,
It is checked whether or not the file capacity required for business processing is insufficient with respect to the current free capacity, and if insufficient, the alarm flag 72 is updated to 1. That is, the alarm flag 72 is updated to 1 when the number of actual files counted by the actual file check is equal to or greater than the maximum number of stored items 68 of the file information 38 for monitoring file in FIG.

At the same time as the actual file status check, the input file data is checked. This input file data check is performed when there is input file data that does not match the attribute of the file item stored in the other DB attribute 80 of the file information for monitoring file in FIG. 6 and the data range. Exclude it as invalid input data and store it in another file.

When the pre-check processing unit 30 completes the actual file status check and the removal of the illegal input data, the automatic file setting process unit 32 executes the automatic setting process for the data file whose alarm flag is 1.

In this automatic setting process, the alarm flag is 1
The existing data stored in the area to be expanded is saved to another area, and then the file area is expanded using the expansion disk.

For files for which file extension has been normally performed by this automatic setting processing, the extended flag 74 in FIG. 6 is updated to 1, and if file extension cannot be performed normally even if an extended disk is used, Abnormality processing unit 28
The abnormal processing by is executed. In this abnormal processing, after the target input file data is cumulatively added to the save file, the unprocessable flag indicating the status of the monitoring file is updated to 1 and the business processing is stopped.

For files for which extension processing has been normally executed or files for which extension processing is no longer necessary, execution is performed based on the monitoring file file information 38b, monitoring file program information 40, and business process execution control statement information 42a. The control statement editing unit 24 executes editing processing.

In the process of editing the execution control statement, parameters for area expansion are calculated for the stalk system file information and flow system file information (temporary file) subjected to the expansion process, and the parameters are reflected in the execution control statement. The business process execution unit 2 for the execution control statement in which the expanded result is reflected
In step 6, business processing is executed.

Next, details of the job processing according to the present invention in FIG. 4 will be described with reference to the flowcharts of FIGS. 8 to 14.

FIG. 8 is a flowchart of the basic processing procedure of the business processing of the present invention in FIG. First, in step S1, input the processed data from the front system,
In step S2, a preliminary check process is executed to check the status of the actual file.

Then, in step S3, it is checked whether or not there is a region shortage. If the region is short, an alarm flag = 1 is discriminated, and in step S4 a file automatic setting process for expanding the region is performed. Of course, the pre-check processing unit 32 also performs processing for removing the illegal input data and storing it in another area.

If there is no insufficient area in step S3, the file automatic setting process of step S4 is not performed for the file. Next, in step S5, an execution control statement edit process is performed to reflect the area parameter corresponding to the file extension process in the execution control statement. Then, in step S6, the business process is executed for the edited execution control statement, and the process result is output to the front system in step S7.

FIG. 9 is a flow chart showing the details of the preliminary check process of step S2 in FIG. In this pre-check process, first, a monitoring file having the contents of FIG. 5 based on the business process name stored in the business process parameter 34 corresponding to the job input from the front system of FIG. 4 in step S1. Job information 36
Get a.

The monitoring file job information 36a has the contents shown in FIG. 5, checks the previous work processing result from the processing status 50, and if the processing impossible flag is 1, it is judged as unexecutable and proceeds to step S7. Execute abnormal processing and terminate abnormally.

The abnormality processing in step S7 is the processing shown in FIG. That is, after the unprocessable flag stored in the processing status 50 of the file information for monitoring file is updated to 1 in step S1, the input file data is cumulatively added to the saved file and saved in step S2, and then in step S3. Stop business processing.

When the business processing is stopped due to the abnormal processing, the business processing is stopped in the operation mode in which the computer business processing system of the present invention executes the business processing by unmanned operation at night, for example. It is desirable to automatically report what you have done to the person in charge's home.

Referring again to FIG. 9, if the processing state 50 is executable in step S2, the process proceeds to step S3,
Monitoring file job information 36 acquired in step S1
The file information 38a for monitoring files of all files existing on the record of a is acquired. Then in step S4,
It is determined whether or not there is a record of alarm flag = 1 for each file information record of the file information for monitoring file acquired in step S3.

If there is a record with the alarm flag = 1, the process proceeds to step S7, and the abnormality process is executed. That is,
If there is a record with alarm flag = 1 at this stage, it means that the expansion processing for the area shortage has failed in the previous business processing, so abnormal processing is performed without further processing and the input data file is processed. The business process is stopped by storing and saving in the save file in the form of cumulative addition.

If the file information record having the alarm flag = 1 does not exist in step S4, the process proceeds to step S5, and it is determined whether or not the database and the general file have a shortage of capacity when it is desired to execute a business process on the input data file. To do.

That is, the input file data is read and the number of input file records of the target file is counted,
This is the file information 38 for the corresponding monitoring file in FIG.
The storage count 66 is updated by obtaining the count count that is added to the count of the current file record of the storage count 66 stored in.

Further, when the number of stored items 66 is updated, the number of updated file records, that is, the number of input file records added to the current number of file records, is compared with the maximum stored number 68, and if the number of stored items is large, there is insufficient capacity. The alarm flag is updated to 1 because it is generated.

Further, in step S6, when the number of input file records is counted, the contents of the input file data are checked. If there is illegal input data, this illegal record is excluded and stored in another file. To determine whether or not the input data is invalid, the attribute of the file item and the data range information provided for the input data check, which is stored in the other DB attribute 80 of the file information 38 for monitoring file of FIG. 6, is used.

This discrimination of illegal input data is specifically to check a format error, and also excludes an error in which a place to be a number is a text as illegal input data.

10 and 11 are flowcharts showing the details of the automatic file setting process of step S4 of FIG. 8 which is performed for a file record having a shortage of space. In this file automatic setting processing, when the file capacity is insufficient, the file area is automatically expanded.

First, the file information 3 for the monitoring file of FIG. 6 obtained as a result of the preliminary check processing in step S1.
8, the file information record with the alarm flag = 1 and the extended flag = 0 is acquired. Next, in step S2, the database and file capacity are calculated from the number of records and the record length.

For the calculation of the file capacity, the storage number prediction formula 88 stored in the monitoring file program information 40 of FIG. 7 is used. Next, in step S3, 3 of the free disk capacity of the storage disk of the actual file and the expansion disk, the file expandable capacity and the free space of the table space are set.
Get one. The total free space can be found by adding these three free spaces.

Then, in step S4, the required file capacity obtained in step S2 is compared with the free space obtained in step S3 to check whether or not the creation area of the expansion target file can be secured.

Since the area cannot be secured if the required file capacity is larger than the free space, abnormal processing is performed in step S11, the input file data is accumulated and saved in the save file, and then the business processing is stopped. If the required file capacity is less than the free space, the creation area of the expansion target file can be secured, so the process proceeds to step S5, and the area expansion parameters of the database and general file are edited.

Subsequently, in step S6, the currently stored data of the extension target file is saved in another area, and then in step S7.
Re-create the extension target file with. Step S7
When the extension target file is recreated in step S8, the saved data is restored to the recreated extension target file in step S8.

Subsequently, the process proceeds to step S9 in FIG. 11, and the file information 3 for the monitoring file of the file that has been expanded.
The maximum number of stored items 68 and the stored DisK name 76 in 8 are updated, and the expanded flag 74 is updated to 1. By updating the file information for monitoring file in step S9, the file information 38a for monitoring file before processing by the process preparation unit 22 in FIG. 4 becomes the file information 38b for monitoring file shown on the output side.

The above steps S5 to S9 are performed by setting the alarm flag = 1 and the expanded flag = in step S10.
Repeat until there is no file record information of 0.

FIG. 13 is a flow chart showing details of the execution control statement editing process in step S5 of FIG. In this execution control statement editing process, the file information of the monitoring file and the program information, which is the information necessary to execute the business process control statement corresponding to the file information record that has been expanded due to the lack of space Is a process of editing.

First, in step S1, the execution control statement editor 24 of FIG. 4 reads the file information 38b for monitoring file, and acquires all record information of alarm flag = 1 in the table. Next, in step S2, it is determined whether or not a record having the alarm flag = 1 exists.
After that, the process returns to the main routine of FIG. 8 and executes the business process of step S6.

If there is a record of alarm flag = 1 in step S2, the process proceeds to step S3, and the business process execution control statement record is read in program units of the monitoring file program information 40. Then step S4
Then, the file name described in the read business process execution control statement record is compared with the file name of the monitoring file information in the table read in step S1, and it is determined in step S5 whether the file names match. Is determined.

If the file names do not match, the process proceeds to step S7, a plurality of business process execution control statement records of the corresponding program unit are written to the output file, and the editing process is not performed.

If the file names match in step S5, the flow advances to step S6 to acquire the monitoring program information based on the program name. Then, in step S8, the storage disk name of the stock file information and the area parameter of the flow file (temporary) are calculated based on the storage disk name of the monitoring file file information and the storage item number prediction formula of the monitoring file program information. Performs the editing process to replace and writes a plurality of relevant records for each edited program to the output file.

The processing of steps S3 to S8 is as follows.
This is repeated until there are no business process execution control statement records in step S9 in FIG. If there is no business process execution control statement record, the process proceeds to step S10, and based on the file information in the table, the alarm flag and the extended flag of the file information for the monitoring file are all updated to 0, and a series of execution control statement editing process is performed. Upon completion, the process returns to the main routine of FIG. 8 to execute the business process of step S6.

Next, a program installed in the computer work processing system of the present invention and a recording medium storing the program will be described. The computer work processing program of the present invention is stored in a portable storage medium such as a CD-ROM or a floppy disk, and is set in a CD-ROM driver or a floppy disk driver of a cluster machine having the hardware configuration shown in FIG. 3, for example. Is installed and stored in the magnetic disk device 7, is loaded into the main storage device 3 from here, and is executed by the CPU 2 to realize the processing functions shown in the functional configuration of FIG.

Further, the computer work processing program of the present invention is recorded in the recording medium of another system or device connected via the network, downloaded by the communication control device to obtain the auxiliary work storage device of the device. Or may be stored in the main storage device.

The computer work processing program thus stored in the storage medium executes the processing shown in the flowcharts of FIGS. 8 to 14.

Is checked in advance, and if there is a shortage, it is automatically expanded,
It is possible to reliably prevent the system from stopping due to the lack of space in the database and general files during operation.

In addition, it is determined whether or not the illegal input data is present in the input data at the time of the preliminary check, and if the illegal input data is present, the illegal input data is excluded from the target of the business process and is separated. By storing it in the file, it is possible to reliably prevent the system from being stopped during business processing due to the presence of input illegal data.

Further, according to the present invention, if it cannot be processed by the preliminary check, or if it cannot be expanded due to the lack of the file area, the job processing is stopped by the abnormal processing. Input data that was input from the front system when processing was stopped can be stored in another file such as a save file and saved, and then business processing can be stopped, so that input data once input from the front system can stop business processing. Even though it is saved and saved in the computer, normal business processing can be facilitated by using the input data that has been saved and saved, without relying on the front system side after recovery by recovery from an abnormal stop. Can be resumed.
