SOLUTION: A numerical value or a character for expressing priority order by which a processing is actually executed based on data contents, the optional date and time and a time with the optional date and time as a start point is made to be a part of or the whole of the file name in the file which the application job system to be worked in a computer uses as input data or output data concerning a method for giving a file name.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for naming a processing file used by an application system running on a computer.

[0002]

2. Description of the Related Art Generally, a computer application system includes:
A file to be processed stored in various storage units of the computer system is input, a process is performed based on (contents of) the content of the file to be processed, and a processing result is output.

In the application system described above,
When an attempt is made to execute a processing event at a desired (future) yet arbitrary date and time based on a processing target file containing desired contents, the following method (,) can be considered. Method. "Processing date / time" is provided in the data item in the file to be processed, and numerical data of the date / time when execution of the process is desired is provided therein. However, in this case, C
It is necessary to constantly monitor the contents of the processing target file from the PU. Then, a physical I / O (Input / Output) is constantly generated from the CPU to the storage unit,
The burden on the I / O site of the storage unit increases. This is remarkable when the storage unit is an external storage device. Method. In addition to the file to be processed, a "processing order control table file" for linking the "processing date, time" and the file name (ID) to be processed is separately provided. In this case, the monitoring target from the CPU at all times is limited to the “processing order control table file”, but physical I / O is constantly generated in the storage unit as in the above case.
Further, a new area on the storage unit is required to store the “processing order control table file”.

[0004]

SUMMARY OF THE INVENTION The present invention does not always monitor the contents of a file to be processed and does not use an unnecessarily large area of a storage unit.
It is an object of the present invention to be able to perform a processing event having desired contents at a desired date and time.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. In the file naming method according to claim 1 of the present invention, in a file used as input data or output data by an application system running on a computer, a numerical value or a numerical value representing a priority in which a CPU of the computer executes processing. The characters are part or all of the file name.

A file naming method according to a second aspect of the present invention represents when a CPU of a computer executes a process in a file used as input data or output data by an application system running on the computer. Numerical values or characters are used as part or all of the file name.

[0007]

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

FIG. 1 shows a processing file 12 formed by an embodiment of a processing file naming method according to the present invention.
Is an example of the application system 2 that uses input / output data. The computer on which the application system 2 can operate is not particularly limited.

The application processing system 2 shown in FIG. 1 includes an application processing unit 4 and a plurality of logical input / output files related to the application processing unit 4. The plurality of logical input / output files are the processing event file 6, the executing file 8, and the processing result file 10. Processing event file 6,
Each of the active file 8 and the processing result file 10 is constituted by a processing file 12 at the physical level. The inside of the application processing unit 4 is divided into two parts according to functions. One is an operation unit 14 and the other is a processing execution unit 16. Operation data of the operator 18, for example, a keyboard (not shown) provided in a computer.
First, the data input by the key input and the data input by clicking the mouse (not shown) are all input to the operation unit 14 first.

Next, one embodiment of the processing file naming method according to the present invention will be described with reference to FIG. In the file name of FIG. 2, ".dat" is used as the extension.
Is always attached. The first half of the file name, that is, ".d
The portion not including "at" is composed of 17-digit characters (for example, alphanumeric characters). For the 17 digits, in order from the left side of FIG. 2, “first digit”, “second digit”,.
These are referred to as “16th digit” and “17th digit”.

The “first digit” indicates “reservation form”. As shown in the figure, there are reservation forms of "immediate processing", "reservation processing", "processing end", "processing restart", and "processing suspension". “Immediate processing” indicates that the file should be processed immediately. "Reservation processing"
This indicates that the file is to be processed according to “processing date and time” described later. "Pause processing"
It indicates that the processing is suspended at "processing date and time". “Resumption of processing” indicates that the suspended processing is to be resumed at “processing date and time”. "Process end" indicates that the process is to be ended by "process date and time". "Pause processing" or "Resume processing" in the file name
For a file with "processing completed", the content of the file is not executed, and the processing being executed at that time is "paused", and the suspended processing is "resume" And "end" the entire process at that time.

In the embodiment of FIG. 2, the value indicating "immediate processing" is "0", the value indicating "reservation processing" is "9", the value indicating "processing end" is "d", and "processing restart". Is "s", and the value representing "processing suspension" is "e".

Twelve digits from "second digit" to "thirteenth digit"
Represents the processing date and time. The year, month, day, hour, and hour to process the contents of the processing file 12 are specified. To be more specific, 4 digits from "2nd digit" to "5th digit" are the processing year (AD); 2 digits from "6th digit" to "7th digit" are the processing month; The two digits from the "digit" to the "ninth digit" are the processing date.-The two digits from the "10th digit" to the "11th digit" are the processing time. Two digits represent the processing amount. However, if the "reservation form" is "immediate processing", it is processed immediately after generation in principle, so
The date and time when the processing file 12 was created are set as the processing date and time.

The four digits from "14th digit" to "17th digit"
Indicates the processing ID. This processing ID is data that is incremented by one each time the processing file 12 is generated, and is a “serial number” that is focused on when the processing file 12 is created. Counted up from "0000",
When it reaches “9999”, it returns to “0000”.

Based on the above concept, the processing file 12
The order in which the file names are assigned to the files is shown in the flowchart of FIG.

Step S02: First, reservation form data is input.

Step S04: Reservation form is "immediate processing"
Is determined. If it is "immediate processing", the process proceeds to step S08. If it is not "immediate processing", the process proceeds to step S06.
Go to

Step S06: The processing date and time are input.

Step S08: In the case of "immediate processing",
The generation date is used as the value of the processing date. This is to realize a function of “immediate processing” that is performed immediately after generation, as described later.

Steps S10 and S12: Processing I
Since D is incremented by one each time the processing file 12 is generated, the counter of the processing ID is incremented by one and set to the processing ID of the generated processing file 12.

Thus, the processing file name naming flowchart ends.

The processing file name is the processing execution unit 16
The processing order is determined and controlled by the processing execution unit 16. The processing order is controlled as follows. << File Processing Order Determination Logic >> (1) The immediate processing (first digit) has a higher processing priority than the reservation processing (first digit). (2) If the processing file names are the same for the same reservation processing (first digit), the processing is executed in ascending order. That is, the processing with the earlier processing date and time is processed first, and if the processing date and time are the same, the processing with the smaller processing ID is processed first. In the case of the processing file names of the same immediate processing (first digit), the processing I
Those with small D are processed first. (3) Immediate processing (first digit) The processing file 12 is processed immediately after generation as a rule. If the processing of another processing file 12 has already been performed immediately after the generation, the processing of the processing file 12 of the immediate processing (first digit) is performed as soon as the processing is completed. (4) The processing file 12 of the reservation processing (first digit) is executed when the “processing date and time” in the file name arrives. (5) In the processing file 12 of the reservation processing (first digit), if the processing of the processing file 12 of the immediate processing (first digit) is being performed at the time when the “processing date and time” arrives, The processing is performed after the processing of the processing file 12 of the immediate processing (first digit) existing at that time ends. (6) Processing end (first digit), processing pause (first digit),
The processing restart (first digit) has the same priority as the reservation process (first digit).

In order to implement the above-described file processing order determination logic, the processing file name given in the above-mentioned processing file name naming flowchart is changed according to the following file processing order determination flowchart every time the processing file 12 is generated. It may be rearranged in the order of processing, and the processing may be performed in that order. The flowchart is shown in FIG.

Step S22: One (new) processing file 12 is created and given a name according to the processing file name naming flowchart (FIG. 3).

Step S24: For each of the processing file names whose reservation mode is "processing end", "processing suspension", and "processing resumption", each is temporarily replaced with the value of "reservation processing". For example, in the embodiment of FIG. 2, the data values of “processing end”, “processing pause”, and “processing restart” are “s” “e”
These are “d”, but these are temporarily “9” (“reservation processing”).
Replace with As described in (6) of << File Processing Order Determination Logic >>, the same priority as "reservation processing" is given to "processing end", "processing suspension", and "processing restart". This is to give a ranking.

Step S26: Sort the processing file names in ascending order.

Step S28: After rearrangement, step S
The data value of “reservation form” replaced by 24 is restored.

With the above, the file processing order determination flowchart ends.

FIG. 5 shows an example of rearrangement of processing file names using the flowchart of FIG. 4 described above.
First, it is assumed that three processing file names are arranged as shown in (1). In these three processing file names, the reservation type is “reservation processing (9)” or “processing suspension (e)”.
Since it is "processing restart (s)", the data values in the reservation form are all considered equal in the rearrangement. Therefore, the sorting is performed according to the value of the processing ID, the processing date and time, and the processing ID.

Next, "processing end (d)""September 1999
It is assumed that a processing file 12 having a file name of “processing date and time of 11:24 on March 15” and “processing ID of 0023” is generated (inside the dotted box in (2)). In this case, the values of the processing date and time are also compared, and the processing file name of the generated processing file 12 is arranged at the end.

Next, "immediate processing (0)", "September 1999"
A processing file 12 having a file name of “11:11, the processing date and time of month 15 (that is, generation date and time)” and “processing ID of 0024”, and “immediate processing (0)” and “1999”
It is assumed that a processing file 12 having a file name of “processing date and time for 11:11 on September 15, 2011 (that is, generation date and time and date)” and “processing ID of 0025” is generated ((3) Inside the dotted box). In this case, since the reservation form of these new processing files 12 is “immediate processing (0)”, if they are rearranged together with the existing processing file names, they are arranged at the top. The two “immediate processing” processing file names are ordered by the processing ID value.

As described above, according to the above-described file processing order determination flowchart, the file processing order determination logic is realized by rearranging the processing order every time the processing file 12 is generated and performing processing in that order.

Even if the processing file 12 is created, it is not rearranged. Instead, the processing execution unit 16 always looks over the file names of all the waiting processing event files 6 according to the above-described file processing order determination logic, and The present invention is realized even in a mode in which the processing file 12 to be processed is determined.

The processing file 12 named by one embodiment of the processing file name naming method according to the present invention is used as input data, and the order of the processing events executed in the application system 2 is as follows. Will be described.

[0035] The content (data) of the processing file 12 is input from an operator via input means (for example, a keyboard, a mouse, etc.) provided in the computer system.
The input is performed on the operation unit 14.

Here, not only the contents (data) of the processing file 12 but also data of "reservation form" and "processing date and time" for determining the processing file name are input. That is, data input relating to, for example, whether this processing file 12 should be started immediately, or when it should be started if it is not started immediately, is performed.

The operation unit 14 also has a counter function for determining the "processing ID".
At the timing when one is newly created, the “processing ID” incremented by one is added. The processing file name is determined based on these data.

[0038] The data input at the operation unit 14
It is created as the processing file 12. Processing file 12
At the time of creation, the processing file name determined above is assigned. The processing file 12 is output from the operation unit 14 and forms a part of the processing event file 6. Here, the newly created processing file 12 is registered in the memory in the processing execution unit 16 as a configuration file of the processing event file 6, similarly to the existing processing file 12. In this registration, the processing file name (ID),
The address of the processing file 12 in the storage unit is stored in the memory. At the time of this registration, the processing file names are rearranged according to the above-described (FIG. 4) file processing order determination flowchart.

The registration status of the processing event file 6 stored in the memory in the processing execution unit 16 is monitored by the processing execution unit 16 as needed.

[0040] The processing execution unit 16 detects the processing file 12 to be processed as needed while monitoring.

[0041] The status of the individual processing file 12 detected above is changed from the processing event file 6 to the running file 8.

[0042] Based on the content (data) of the file 8 being executed, the processing execution unit 16 executes the processing.

. The output data generated by the above processing is stored in the processing file 12 which is the executing file 8.
Make additional edits. Then, the status is changed to the processing result file 10 and is set as the output file of the application system 2.

The above is the processing order of the processing events performed in the application system 2. In the application system 2, the processing file 1 is stored on the basis of the processing file name (ID) stored in the memory in the processing execution unit 16.
Since the processing priority of No. 2 is determined, the determination (processing)
Is much faster than in the prior art. Further, the storage unit does not need to have the same capacity as the related art.

In the application system 2, the application processing unit 4 is divided into an operation unit 14 and a processing execution unit 16 according to functions. It is possible to obtain the above-described effects by using the processing file 12 named by the processing file name naming method.

Further, the processing file naming method according to the present invention is not limited to the above embodiment. For example, in the "processing date and time", not only "hours and minutes" but also "seconds" or less time units may be included.On the other hand, "hours" may be described and no lower time units may be included. It may be. The “processing ID” may not be provided.

[0047]

By using the processing file naming method according to the present invention, the following effects can be obtained.

In the application system using the processing file 12 named by the above-mentioned processing file name naming method, the processing file 12 is stored on the basis of the processing file name (ID) stored in the memory in the processing execution unit 16. Are determined. Therefore, the determination (processing) is much faster than in the prior art. Further, the storage unit (external storage device, auxiliary storage device) does not need the capacity as in the related art.
