Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file update management method capable of minimizing confirmation upon file update and a computer-readable recording medium on which the program is recorded.

[0002]

2. Description of the Related Art Generally, when a file is transmitted / received via a frame relay network, the network itself does not perform retransmission due to a transmission failure during communication or the like. You need to confirm the file transfer.

FIG. 4 is a diagram showing a file management method when confirming the transfer of a file via a frame relay network and updating the file at the transmission destination.

[0004] New or modified program files are sequentially transmitted from centers A and B (hereinafter collectively referred to as centers) in which application programs are developed through a frame relay (FR) network NET.
The file management server 100 receives this and temporarily stores it in the reception area 101.

[0005] The file management server 100 updates the file by storing the file in the file storage DB1, but performs a step-by-step confirmation process before that.

First, "file arrival confirmation processing" is performed.
That is, the file list separately sent from the center and the actual file stored in the reception area 101 are collated. If they do not match, the file arrival confirmation processing will result in an error.

On the other hand, when the file arrival confirmation processing ends normally, the files in the reception area 101 are moved to the work area 102 by the reception processing. Also at this time, the capacity of the work area 102 is confirmed, and an error occurs in the reception processing when the capacity is insufficient.

[0008] If there is an error in the above confirmation processing, the file management server 100 sends an alarm signal to the workstation 2 to notify the operator of the abnormality. On the other hand, when there is no error, the file is stored in the file storage unit DB1 and updated by batch processing. The file name and the update date are recorded in a registration date management table (not shown).

[0009]

As described above, in the conventional file update management method, various types of confirmation processing are performed stepwise before the file is updated, and an alarm signal is transmitted when an error occurs. An error is notified.

[0010] However, even if an abnormality is notified before the file is updated, a recovery process such as requesting the center to retransmit the file after that is necessary. Therefore, it is convenient to make these confirmation processes unnecessary and prevent the alarm from being sent. However, the center deletes the file after a predetermined number of storage days after sending the file, so the minimum necessary confirmation processing is performed. Is necessary.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a file management method capable of minimizing confirmation when updating a file.

[0012]

In order to solve the above-mentioned conventional problems, a file update management method according to a first aspect of the present invention provides a method of updating a file when an update date of a file to be updated is recorded. Obtaining the recorded update date and adding a predetermined number of days to the update date to obtain an update date, wherein the current date is the same as or later than the obtained update date. And sending an alarm signal when.

According to the first aspect of the present invention, an alarm signal is transmitted when the current date is the same date as or later than the update date, so that various confirmation processes before updating the file are unnecessary. In other words, file updates can be managed with the minimum necessary processing.

A file update management method according to a second aspect of the present invention is the file update management method according to the first aspect, wherein the type of the alarm signal is determined based on a difference between the update date and the current date. It is characterized by making it different according to.

According to the present invention, different alarm signals are transmitted according to the difference between the update date and the current date, so that the number of days remaining until the update date can be ascertained.

A file update management method according to a third aspect of the present invention is the file update management method according to the first or second aspect, wherein the updated file is transmitted from a transmission source via a network. It is transmitted and updated at the destination, and the number of days for obtaining the update date is:
The file is set according to the number of days for which the file is stored at the transmission source.

According to the third aspect of the present invention, according to, for example, the number of storage days after transmission of a file at the transmission source,
Since the predetermined number of days is set and the number of days is added to the update date to obtain the update date, it is possible to avoid the inconvenience that the alarm signal is transmitted after the file is deleted at the transmission source.

In order to determine the predetermined number of days in accordance with the number of storage days, one of a method of determining a difference between the two and a method of determining a ratio of the two can be adopted.

According to a fourth aspect of the present invention, there is provided a file update management method according to the third aspect, wherein the network is a frame relay network.

According to the fourth aspect of the present invention, file updating via a frame relay network in which the network itself does not retransmit a file can be managed with only a minimum necessary confirmation.

According to a fifth aspect of the present invention, there is provided a computer-readable recording medium on which a file update management program is recorded, wherein a file update management program for recording an update date of a file to be updated as appropriate is recorded. Obtaining a recorded update date, adding a predetermined number of days to the update date to determine an update date, and the current date being the determined update date. Sending an alarm signal when the date is the same or a later date.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a file update management method according to the present invention and a recording medium on which the program is recorded will be described below in detail with reference to the drawings.

FIG. 1 is a diagram showing a configuration and a use form of a file management server 1 according to an embodiment of the present invention.
The frame relay (FR) network NET and each of the centers A, B, etc. are the same as those in FIG.

The file management server 1 is connected to the centers A and B via the frame relay network NET, and includes a file storage unit DB1 for storing and updating files sequentially transmitted from these centers.

The file management server 1 also includes an update date management table TB1 in which the update date of the file in the file storage unit DB1 is recorded, and a monitoring condition table having monitoring conditions for monitoring the file update in the file storage unit DB1. A TB 2 and an update management tool 11 that monitors file updates based on the monitoring conditions and sends an alarm signal to the workstation 2 according to the result are provided. The update date management table TB1 and the monitoring condition table TB2 are configured in a storage device such as a hard disk.

More specifically, in the file management server 1, a predetermined number of days (referred to as an alarm transmission prohibition day) starting from the day after the previous file update date is defined as an “period during which the transmission of the alarm signal is prohibited”. In the monitoring condition table TB2, the alarm transmission prohibition days and the like are set for each file.

The update management tool 11 is started, for example, every day or every other day according to the necessity of management, performs a condition branching process based on the contents of the update date management table TB1 and the monitoring condition table TB2, and executes a port of the CPU. , An alarm is sent to the workstation 2 or a normal notification is made. The update management tool 11 is specifically embodied by, for example, causing a CPU of the file management server 1 to read and execute a file update management program having each step described below. The file update management program may be stored in a computer-readable recording medium. The embodiment of the present invention can be reproduced on the computer system by reading and executing the recording medium by a CPU of a computer system such as the file management server 1. Here, the recording medium is a computer-readable recording medium on which a program can be recorded, such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, and a magnetic tape.

FIG. 2 is a diagram showing items in the update date management table TB1 and the monitoring condition table TB2 and their contents.

The file name F1, F2, F3, etc. of each file transmitted from the center is recorded in the item "file name" of the update date management table TB1, and the file storage unit is stored in the item "last update date". The date when the file was last updated, that is, the last update date is recorded in DB1.

In the item "file name" of the monitoring condition table TB2, the file names F1, F
2, F3, and the like are recorded, and in the item “number of days for which alarm transmission is prohibited”, the number of days for which alarm transmission is prohibited for each file, such as 5, 10, and 40, are set. The item “number of storage days” includes the number of storage days from the transmission of each file at the center until the file is deleted, 7 days, 30 days.
Date, 60 days, etc. are recorded for reference.

In the file management server 1, the number of days for which alarm transmission is prohibited is set to be smaller than the number of days for storage.
That is, the file is reliably stored and updated in the file storage unit DB1 several days before the date at which the file is deleted at the center, otherwise, the operator is warned by an alarm signal, and a request for retransmission is made. It is possible to deal with. Conversely, since the next file update needs to be performed between the previous update date and the date on which the alarm transmission prohibition days are added, it can be said that this date is the file update date.

Next, the operation of the embodiment according to the present invention will be described. The file management server 1 records the update date in the update date management table TB1 when the file is updated in the file storage unit DB1, separately from the following processing.

FIG. 3 is a flowchart showing the flow of processing by the update management tool 11. Update management tool 11
Is activated at a predetermined time, first, an update date management table TB1 (or a monitoring condition table TB2).
(Step S1). For example, assume that the file F1 is selected. Then, the “last update date (2000 3
13) is read from the update date management table TB1 (step S3). This date is referred to as (A). And
The “alarm transmission prohibition days” corresponding to the file F1 is read from the monitoring condition table TB2 (step S5).
This alarm transmission prohibition day is assumed to be (B).

These data are stored in each of the tables TB1 and TB2.
, The update management tool 11 sets the current date acquired from the internal timer to the number of days (B) in the date (A).
It is determined whether the date is the same date as or later than the update due date obtained by adding (step S7).
Here, if it is determined that the date is the same or a later date (YES), the update management tool 11
Then, an alarm signal indicating that the file has not been updated before the due date is transmitted through the port of the CPU (step S9).

On the other hand, if it is determined in step S7 that the current date is a date before the update deadline (NO), a notification that the file update is normal is sent to the workstation 2 (normal notification). ) Is performed through the port of the CPU (step S11). At this time, the update management tool 11
Makes the type of alarm signal different according to the difference between the current date and the date of (A) + (B). For example, the frequency and amplitude of the signal are made different.

The workstation 2 which has received the normal notification or the alarm signal displays a normal notification on the screen, or performs a display corresponding to the type of the alarm signal. Therefore, the operator who operates the workstation 2 can recognize whether or not the update to the file storage unit DB1 has been performed before the update date for each file, and also recognizes the number of remaining days until the update date. can do. Note that depending on the difference between the number of days of file storage at the center and the number of days of alarm transmission prohibition, when the current date is the same as the update date, normal notification may be performed instead of alarm transmission.

When the processing in step S9 or step S11 is completed, the update management tool 11 determines whether the file F1 currently being processed is the last unprocessed file in the update date management table TB1 (or the monitoring condition table TB2). It is determined whether or not it is (step S13). here,
If it is determined that the file is not the last file (NO), the process returns to step S1, an unprocessed file is selected, and thereafter, the same processing as that described above is performed. On the other hand, when it is determined that the file is the last file (YES), the above series of processing ends.

As described above, according to the file update management method and the recording medium according to the embodiment of the present invention, the current date is obtained by adding a predetermined number of days to the update date. Since the alarm signal is sent when the date is the same as or later than the obtained update date, confirmation at the time of updating the file can be minimized.

Also, since the type of the alarm signal is changed according to the difference between the update date and the current date, the number of days remaining until the file update date is grasped at the workstation to which the alarm signal is transmitted. be able to.

Further, the file is, as in the embodiment,
When the data is transmitted from the transmission center such as the center via the network and updated at the transmission destination, the number of days for which alarm transmission is prohibited is determined according to the number of days the file is stored at the transmission source. The inconvenience that occurs after deletion can be avoided.

[0041]

As described above, according to the present invention,
An alarm signal is sent when the current date is the same date as or later than the update date obtained by adding a predetermined number of days to the update date, so confirmation when updating the file is minimized. can do.
