[Industrial application field]

The present invention relates to a batch job processing time calculation device.

For example, in financial computer systems, etc., batch processing such as creating deposit masks and deposit accumulation masks is performed based on the day's transaction data aggregated from each branch after business hours. For this reason, an estimate of the processing time for patch jobs is required before the system goes live.

For this reason, estimates have traditionally been made by hand while looking at the source program that executes the job, but this requires consideration of the performance of the computer system that executes the job, the amount of data to be processed, etc., which requires a large amount of labor. was needed.

Therefore, there is a need for a processing time calculation device that easily calculates the processing time of a patch job.

[Problems to be solved by conventional technology and invention]

Conventionally, the processing time of a patch job has been estimated by calculating the actual running time or manually by setting a certain model such as the amount of data to be processed.

However, since each computer system that executes the job has a combination of central processing units CPU, input/output devices, etc. with various performances, actual running cannot be expected. Estimates are often calculated.

This hand-calculated estimate is, for example, the number of executed instructions.

Processed data 1. This is done based on the CPU capacity, transfer time of input/output devices, etc., and a system with a large number of programs such as a financial system requires an extremely large amount of estimated man-hours.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a simple patch job processing time calculation device used for estimating patch job processing time.

7).

[For production]

The program that executes the patch job is analyzed, and among the instructions used, the instructions are classified and totaled for each processing unit, such as instructions processed by the computer and instructions processed by the input/output device.

In the performance table 8, the processing time per instruction and the performance per processing unit of each processing unit are registered for each model, and the calculation unit 5 refers to the performance table 8 based on the model name of each specified processing unit and determines the processing The execution time of the program is calculated based on the amount of data and the number of instructions used.

As described above, in addition to classifying and aggregating each processing unit (computer, input/output device) that executes the instructions that make up the program, we also aggregate the processing time in each processing unit that executes those instructions to process patch jobs. In order to calculate the time, the processing time can be estimated quickly and easily by inputting the operating environment conditions such as the performance (model) of each part of the computer system and the amount of data.

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

FIG. 2 is a block diagram of the processing time calculation device of the embodiment, and FIG. 3 is an operation flowchart.

This embodiment shows an example of calculating the processing time of a series of batch jobs (A-X) using a magnetic disk device as an input/output device.

In FIG. 2, 2A to 2x are source programs for batch jobs stored in the external storage device 10, and 3 is an analysis unit that sequentially reads source programs 2A to 2X for batch jobs 8 to X and executes instructions. 4 is an aggregation table that stores the aggregation results, and 5 is a calculation unit that classifies and aggregates all instructions by processing unit (in this case, central processing unit CPU and magnetic disk device). 6 is a calculation unit that calculates the CPU time, input/output time, and total processing time while referring to the CPU performance table 8a and the input/output device performance table 8b based on the CPU performance table 8a and the input/output device performance table 8b; 6 is a CPU model name, input/output device model name, data amount, etc. 7 is an output section that outputs the calculation results as a list; 9 is an input/output control section; 8a is a CPU performance table that shows the average processing time per instruction for each CPU model; 9 For example, C0BOL. 8b is an input/output device performance table in which MIX, etc. are registered, and in the case of magnetic disk drives, transfer speed, average positioning time, average rotational waiting time, etc. are registered for each model, along with CPU performance table 8a. Corresponding to performance table 8 in FIG. 1, l is the processor.

Note that the average instruction execution time (INST) is the performance of the CPU.
For example, if the source program is written in COBOL, use the COBOL MIX required for each model.

The calculation operation will be explained below with reference to FIG.

(11 Batch job A-X source program 2A-2
Load x into the external storage device 10 and enter the CPU model name.

Enter the model name of the input/output device and the amount of data to be processed (number of blocks in transfer unit).

(2) The analysis section sequentially reads the source programs 2A to 2x, recognizes and analyzes instructions, and reads, for example, the READ instruction.

The commands are classified into WRITE commands (input/output commands), CALL commands, other commands, etc., and are totaled in a total table 4, respectively.

At this time, if there is a CALL instruction that calls a subroutine, that subroutine is also counted.

Incidentally, the analysis of the source programs 2A to 2X uses a method commonly used in compilers and the like.

(3) When the above analysis and aggregation processing is completed, the calculation unit 5
Based on the operating conditions input from the input unit 6, refers to the CPU performance table 8a and the input/output device performance table 8b, and calculates the processing time based on the following calculation formula.

CPU time = total number of instructions x (COBOL MIX')
Input/output time = (READ - number of R1τE instructions)

Processing time = CPU time, input/output time) Patch The above calculation is performed for each job A to X, and the total CPU time and total processing time are totaled.

(5) Edit the above calculation result and output it to the output section 7.

In the above embodiment, the output processing time of the batch processing result is omitted because it is assumed that the output processing time is multi-processed with the next batch job.

It is also possible to take into account the processing time of the operating system O8. For example, if a batch job file is composed of multiple load modules, the processing time can be calculated in detail by adding the load time using the CALL instruction. .
