Description

Interrupt reentry method and system for batch processing program

Technical Field

The invention relates to the technical field of reentry of computer application programs, in particular to an interrupt reentry method and system for a batch processing program.

Background

During the running of the batch processing program of the core bank host, the running of the batch processing program is interrupted due to data exception and system exception. Each minute of the time window of the batch processing program is very precious, and the time window is related to key events such as whether the bank can be operated in time. Therefore, after the fault is eliminated, the breakpoint of the batch program is restored, and data reentry is performed on subsequent data of the breakpoint. Breakpoint reentry (or interrupt reentry) refers to the process of batch program breaking into interrupts during operation, and resuming operation from the breakpoint by using reentry mechanism.

The main problem of data reentry in the prior art is reentry of output files. The breakpoint re-entry mechanism is to re-enter input data and output data according to the primary key of the data table of the last COMMIT recorded. However, for the breakpoint reentry of files, because the number of output files is not fixed, and neither the input file nor the output file has a primary key value, the uniqueness of the input file cannot be recorded. If the method of the key value is forced to be carried out, structural reconstruction needs to be carried out on a plurality of different input files again, and the unique primary key value is added artificially. The technical scheme improves the complexity of file reentry, and has no universality and low processing efficiency. The COMMIT refers to issuing a COMMIT command when a batch processing program updates data in a database, the data can only take effect in the database, and the primary key value is information which can uniquely determine an input file record.

Therefore, how to provide a breakpoint reentry technology with good universality and high efficiency for files is a technical problem to be solved urgently.

In view of the defects in the prior art, the present invention provides a method for resuming interrupts in a batch process, a flowchart of which is shown in fig. 1, and the method includes:

s101: in the process of batch processing of input file records in input files, after each input file record is processed, acquiring the sequence number of the processed input file record and the sequence number of the last output file record obtained by processing all the processed input file records; wherein all output file records are stored in the output file and are sequentially numbered.

S102: and periodically updating the sequence number of the input file record and the sequence number of the last output file record into a breakpoint table.

S103: and when the batch processing program is interrupted, executing interruption reentry on the input file and the output file according to the sequence number of the input file record and the sequence number of the corresponding last output file record recorded in the breakpoint table.

The execution main body of the interrupt reentry method of the batch processing program shown in fig. 1 may be a bank background server, and it is known from the flow shown in fig. 1 that each input file record in an input file is sequentially executed, each input file record generates at least one corresponding output file record after being executed, and sequentially stores the generated output file records into an output file in an additional manner, after the storage is successful, the input record is considered to be processed completely, and then processes the next input file record in the input file until all the input file records are executed completely. And recording all output files in the output file in a sequence number, starting to add the output file record newly stored each time after the last output file record in the output file, and updating the output file. And according to the appointed period, updating the sequence number of the input file record which is successfully processed last and the sequence number of the last output file record corresponding to the input file record into the breakpoint table. And when the batch processing program is interrupted, executing interruption reentry on the input file and the output file according to the sequence number of the input file record and the sequence number of the corresponding last output file record recorded in the breakpoint table. The invention records the reentry of the input file and the output file of the recovery breakpoint according to the stored input file record and the output file, and has the advantages of good universality and high efficiency.

For example, the input file is a, and the sequence numbers of the records of the input files are a01, a02, … …, AN, and N are positive integers. The output file is P, the sequence numbers of the stored output file records are P01, P02, … …, PM and N are positive integers. The number of corresponding output file records generated after each input file record is executed is uncertain, that is, after the input file record of A01 is executed, the corresponding output file records generated are P01-P08; after the input file record of a02 is executed, the generated corresponding output file records are P09 to P10, after the input file record of a03 is executed, the generated corresponding output file records are P11 to P15, after the input file record of a04 is executed, the generated corresponding output file records are P16 to P21, after the input file record of a05 is executed, the generated corresponding output file records are P22 to P25, after the input file record of a06 is executed, the generated corresponding output file records are P26 to P35, and the like, which is not limited by the invention.

In one embodiment, as shown in fig. 2, the step S102 of periodically updating the sequence number of the input file record and the sequence number of the last output file record into the breakpoint table includes the following steps:

s201: and updating the serial number of the input file record and the serial number of the last output file record into the cross section data table in real time.

In the specific implementation of S201, after each input file record is successfully processed, the obtained serial number of the input file record and the serial number of the last output file record in the corresponding output file are recorded as cross-sectional data. And recording the data of the cross section data in real time as a cross section data table.

Table 1 is a cross-sectional data table after the input file record a01 is successfully processed, and as shown in table 1, after the input file record a01 is successfully processed, the corresponding last output file record serial number is P08, and the cross-sectional data a01 of the input file and the cross-sectional data P08 of the output file are updated to the cross-sectional data table in real time.

Table 2 is a cross-sectional data table after the input file record a02 is successfully processed, and as shown in table 2, after the input file record a02 is successfully processed, the corresponding last output file record serial number is P10, and the cross-sectional data a02 of the input file and the cross-sectional data P10 of the output file are updated to the cross-sectional data table in real time. And by analogy, after the current input file record is successfully processed, the sequence number of the current input file record and the sequence number of the corresponding last output file record are updated into the cross section data table in real time.

TABLE 1

Inputting cross section data of file	Cross section data of output file
		A01	P08

TABLE 2

Inputting cross section data of file	Cross section data of output file
		A02	P10

S202: and periodically updating the serial number of the input file record and the serial number of the corresponding last output file record in the cross section data table into the breakpoint table.

When the step S202 is implemented specifically, the sequence number of the input file record and the sequence number of the corresponding last output file record recorded in the cross-section data table are updated to the breakpoint table according to the specified period.

The specified period may be that after every K input file records in the input file are processed, the sequence number of the newly acquired input file record and the sequence number of the corresponding last output file record are updated into the breakpoint table.

For example, after each successful processing of the input file a, K equals 3 input file records, the sequence number a03 of the input file record and the sequence number P15 of the corresponding last output file record recorded in the cross-section data table are updated into the breakpoint table.

Data after the data is updated for the first time in the breakpoint table is shown in table 3, and after the input file record a06 of the input file a is successfully processed, the sequence number of the last output file record corresponding to the input file record a06 and the input file record a06 recorded in the cross-section data table is updated to the breakpoint table. And analogizing in turn, updating the data in the breakpoint table once after 3 input file records of the input file A are successfully processed. The specific choice of K is usually a common divisor of the input file records in the input file, and the value of K may be a larger common divisor of the input file records selected above in view of the efficiency and performance of the batch process.

TABLE 3

Entering a sequence number of a file record	Sequence number of output file record
		A03	P15

It is set that an interruption of the batch program occurred at the time of the processing of the input file record a05, and at this time, since the input file record a05 failed in the processing, only the cross-sectional data at the time of the success of the a04 processing was stored in the cross-sectional data table. While part of the output file record of the input file record a05 has been stored in the output file P. Since K is 3, the data of the breakpoint table is updated only after the processing of the input file record a06 is successful, and thus the data in the breakpoint table is still as shown in table 3 when the processing of the input file record a05 fails.

In one embodiment, as shown in fig. 3, step S103 performs interruption reentry on the input file and the output file according to the sequence number of the input file record and the sequence number of the corresponding last output file record recorded in the breakpoint table, including:

s301: and deleting the output file record after the corresponding output file record in the output file according to the sequence number of the last output file record to obtain an updated output file.

Fig. 4 is a schematic structural diagram of the output file P. In the specific implementation of S301, as shown in fig. 4, it is set that when the batch program is interrupted during the processing of the input file record a05, the sequence number P15 of the stored output file record is obtained from the breakpoint table, and the output file record P16 and all the output file records following the output file record (since the input file record a04 has generated the output file records P16 to P21 and a05 has generated partial output file records), the output file is updated. Fig. 5 shows the structure of the updated output file P, which stores only the output file records P01 to P15, as shown in fig. 5.

S302: and starting processing from the next input file record of the corresponding input file record in the input files according to the serial numbers of the input file records, and adding the corresponding output file record generated after processing to the updated output file.

Fig. 6 is a schematic diagram of the structure of the input file a, and fig. 7 is a structure of the output file P after the input file record a04 is successfully processed. In specific implementation, as shown in fig. 6, when the batch program is interrupted during the processing of the input file record a05 and the re-entry of the input file is executed, at this time, the serial number a03 of the stored input file record is obtained from the breakpoint table, the batch processing is resumed from the input file record a04 next to the input file record a03 in the input file, and the corresponding output file record generated after the processing of the input file record a04 is added to the updated output file P, and the serial number of the corresponding output file record generated after the processing of the input file record a04 is sequentially numbered from P16 and stored in the updated output file P, as shown in fig. 7. The remaining input file records a05, a06, a07, etc. of the input file are then processed in sequence to effect a reentry of the output file.

In one embodiment, the input files are multiple, and all the input files are processed in batch in parallel; wherein, the input file with the largest number of input file records is taken as the main file.

In a specific implementation, the input file is set to A, B, C and the output file is set to P, and the batch process concurrently performs parallel processing on the input file A, B, C. The parallel processing means that after the input file record A01 of the input file A is successfully processed, corresponding output file records generated are P01-P08; then processing the input file record B01 of the input file B, and generating corresponding output file records from P09 to P10; after the input file record B01 is successfully processed, the input file record C01 of the input file C is processed, the generated corresponding output file records are P11 to P13, and then the input file record A02, the input file record B02, the input file record C02, the input file record A03, the input file record B03 and the input file record C03 are sequentially executed, and the input files are processed in parallel in the same way.

The input files are in a parallel processing relation, but the processing process of each input file record is in a serial processing relation, and the corresponding output file record generated by each input file record is additionally generated into the output file. The input file with the largest number of input file records is taken as the main file, the number of the input file records with the input file of A in the application is set to be 9, the number of the input file records with the input file of B is set to be 20, and the number of the input file records with the input file of A is set to be 8, so that the input file of B in the application is taken as the main file, but the sequence for processing the input files can be A, B, C according to the sequence of the input files or can be processed from the largest number to the smallest number of the input file records, and the invention is not limited to the above. The present invention processes the input files in parallel in the order of input file A, B, C.

In one embodiment, step S101 obtains the serial number of the processed input file record and the serial number of the last output file record obtained from all the processed input file records, including;

in the process of batch processing the input file records of each input file, after the processing of each input file record is completed, the sequence number of the input file record corresponding to each processed input file and the sequence number of the last output file record obtained by processing all the input file records are obtained.

In specific implementation, fig. 8 is a diagram of correspondence between partial input file records and output file records, and as shown in fig. 8, after the processing of the input file records a01, B01, and C01 of the input file is completed, the sequence numbers of the last output file record in the output file P corresponding to each input file record are P08, P10, and P13. After the processing of the input file record a02 is completed, the generated output record is added to the output file P from P14, after the processing of the input file record B02 is completed, the generated output record is added to the output file P from the corresponding output file record generated by the input file record a02, after the processing of the input file record C02 is completed, the generated output record is added to the output file P from the corresponding output file record generated by the input file record B02, and so on.

In one embodiment, as shown in fig. 9, step S102 periodically updates the sequence number of the input file record and the sequence number of the last output file record into the breakpoint table, including:

s901: and updating the serial numbers of the input file records corresponding to the input files and the serial number of the last output file record obtained by processing all the input file records into the cross section data table in real time.

In specific implementation, after one input file record of each input file is successfully processed, the obtained serial number of each input file record and the serial number of the last output file record obtained by processing all the input file records are recorded as cross-section data. And recording the data of the cross section data in real time as a cross section data table. Table 4 is a table of cross-sectional data after successful processing of the input file records a01, B01, and C01, as shown in table 4.

TABLE 4

S902: and periodically updating the serial numbers of all input file records and the serial number of the last output file record in the cross section data table into a breakpoint table.

In the specific implementation, the input file B is set as the master file because the input file B has the largest number of input file records. And updating the serial numbers of all input file records and the serial number of the last output file record in the cross section data table into the breakpoint table by taking the period set by the main file as the period for updating the data in the breakpoint table.

In one embodiment, step S102 periodically updates the sequence number of the input file record and the sequence number of the last output file record into a breakpoint table, including:

and after the set number of input file records of the main file are processed, updating the sequence number of the input file record of each newly acquired input file and the sequence number of the last output file record into the breakpoint table.

In specific implementation, the period of the main file B is taken as the period for updating the breakpoint table. The period setting of the main file B refers to the specific implementation process of step S202. And setting the set period of the main file B as updating the data in the breakpoint table after the record processing of every 5 input files is completed.

For convenience of illustration and calculation, in this embodiment, the input file record of the input file a is taken as a01-a09, 9 input file records are counted, and the set period is that the data in the breakpoint table is updated after the processing of every 3 input file records is completed. The input file record of the input file B is B01-A20, the total number of the input file records is 20, and the set period is that the data in the breakpoint table is updated after the record processing of every 5 input files is completed. The input file records of the input file C are C01-C08, the number of the input file records is 8, and the set period is that the data in the breakpoint table is updated after the record processing of every 4 input files is completed.

In parallel processing the input file A, B, C, when the processing of the input file records a05, B05, and C05 is completed, the sequence numbers a05, B05, and C05 of the input file records and the last output file record Pk in the output file generated last after the processing of the input file records a05, B05, and C05 is completed are updated to the breakpoint table, as shown in table 5.

TABLE 5

After the processing of the input file records a08, B08, and C08 is completed, the input file C is processed, but the breakpoint table is not updated, and the batch processing program is continuously executed until the processing of the input file record B10 is completed, and the sequence numbers a09, B10, and C08 of the input file records and the last output file record (the sequence number of the last output file record corresponding to B10 is set to Pj) in the output file generated last after the processing of the input file records a09, B10, and C08 are completed are updated to the breakpoint table, as shown in table 6.

TABLE 6

Because the input file records of the input files a and C are processed completely, until the input file records B20 are processed completely, only the serial number of the input file record and the last output file record in the input and output files corresponding to all the processed input file records are updated to the breakpoint table each time, and the serial numbers of the input file records of the input files a and C are not updated any more.

In one embodiment, as shown in fig. 10, step S103 performs interruption reentry on an input file and an output file according to a sequence number of an input file record and a sequence number of a last output file record recorded in a breakpoint table, including:

s1001: and deleting the output file record after the corresponding output file record in the output file according to the sequence number of the last output file record to obtain an updated output file.

In specific implementation, when the batch program is interrupted during the processing of the input file record B06, the serial number Pk of the stored output file record is obtained from the breakpoint table, and the output file record P (k +1) in the output file and all subsequent output file records are deleted to update the output file.

S1002: and according to the sequence number of the input file record of each input file, starting processing from the next input file record of the input file record corresponding to each input file, and adding the corresponding output file record generated after processing to the updated output file.

In specific implementation, when the batch program is interrupted during the processing of the input file record B06 and the input file is re-entered, the stored input file records a05, B05 and C05 are acquired from the breakpoint table, the batch processing is resumed from the next input file record a06 of the input file record a05 in the input file, the corresponding output file record generated after the processing of the input file record a06 is added to the updated output file P, and the sequence number of the corresponding output file record generated after the processing of the input file record a06 is sequentially numbered from P (k +1) and stored in the updated output file P. And then sequentially processing the next input file record B06 of the input file record B05 of the input file B, processing the next input file record C06 of the input file record C05 of the input file C after the input file record B06 is successfully processed, and performing batch processing on all the input files in parallel, thereby realizing the reentrant of the output file.

The present invention further provides a method for resuming interrupt of a batch processing program, a flowchart of which is shown in fig. 11, the method comprising:

s1101: in the process of batch processing of the input file records of each input file, after the processing of each input file record is completed, acquiring the sequence number of the input file record corresponding to each processed input file and the sequence number of the last output file record obtained by processing all the input file records; all output files in the output files are recorded with serial numbers, and all input files are subjected to batch processing in parallel.

As can be seen from the flow shown in fig. 11, in the process of batch processing the input file records of each input file, after each input file record is processed, the sequence number of the input file record corresponding to each processed input file and the sequence number of the last output file record obtained from all the processed input file records are obtained. And periodically updating the serial number of each input file record and the serial number of the last output file record into a breakpoint table. And when the batch processing program is interrupted, respectively executing interruption reentry on each input file and each output file according to the serial number of the input file record and the serial number of the last output file record of each input file recorded in the breakpoint table. The invention records the reentry of each input file and each output file of the recovery breakpoint according to the stored input file records of a plurality of input files and the output files corresponding to all the processed input file records, and has the advantages of good universality and high efficiency.

The application sets input files A, B and C, an output file P, and a batch processing program simultaneously carries out parallel processing on the input files A, B and C. The parallel processing means that after the input file record A01 of the input file A is successfully processed, corresponding output file records generated are P01-P08; then processing the input file record B01 of the input file B, and generating corresponding output file records from P09 to P10; after the input file record B01 is successfully processed, the input file record C01 of the input file C is processed, the generated corresponding output file records are P11 to P13, and then the input file record A02, the input file record B02, the input file record C02, the input file record A03, the input file record B03 and the input file record C03 are sequentially executed, and the input files are processed in parallel in the same way.
