Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an application cooperation processing method in file transfer, and more particularly to an application cooperation processing method in file transfer when a file transfer program and an application (user) program that processes a transfer file are linked. Regarding

In order to process a file transferred by a file transfer program (transfer file), it is usually necessary to link an application program that performs this processing with a file transfer program.

[0003]

2. Description of the Related Art FIG. 8 shows an example of a conventional file transfer processing system. In this method, the file transfer program 51
Provides the application interface 52 to the application program 53, thereby cooperating with each other.

In FIG. 8, first, in order to perform the transfer, the application program 53 declares the use of the transfer function (open) to the transfer program 51 via the application interface 52, and similarly waits for an event (event). To occur.

In this state, when there is a transfer request from the communication destination (program) 1 for file transfer to the file transfer program 51, the application program 53 which receives this request via the application interface 52 requests the transfer. The file name in the file is checked to create data for the file 4 and the library is created, and transfer start is notified to the file transfer program 51 via the application interface 52. The file transfer program 51 returns this transfer start to the communication partner 1 as a response corresponding to the previous transfer request.

[0006] Next, the file transfer program 51 transfers the library (file 4) created by the application program 53 to the communication partner 1, and when this is completed, the application interface 52 notifies that fact.
The application program 53 is notified via.

The application program 53 checks whether or not the file transfer is normally completed, and processes the file 4 in accordance with the result. When this processing is completed, a message to that effect is sent via the application interface 52. Notify 51. Upon receiving this notification, the file transfer program 51 returns the transfer end to the communication partner 1.

[0008]

According to the above-mentioned prior art, the function for operating the file transfer is originally the file 4
There is a problem that the application program 53, which is a program for processing, must have.

That is, for one file transfer, the application program 53 opens, event,
Notification of transfer start and transfer end must be given each time. Further, the application program 53 has to perform a file name search and a process based on it, and a normal / abnormal end check and a process based on it. Therefore, the load of the application program 53 is heavy.

Further, since the application program 53 has to be aware of such processing, there is a problem that the application program 53 becomes complicated and a burden for its development is heavy. Further, there is a problem that the application program 53 must be developed so as to have the contents corresponding to the file transfer program 51 at all times.

In addition to the above-mentioned conventional technique, a file transfer program 51 and an application program 53 are provided.
File transfer program 5
There is a method in which 1 is started and the application program 53 performs the processing according to the end status.

However, even with this method, the function for operating the file transfer is provided by the application program 53.
In addition to this, it is difficult to handle multiple transfers at the same time, and the center system cannot operate.

An object of the present invention is to provide an application cooperation processing method for file transfer, which reduces the load on the application program in cooperation between the file transfer program and the application program.

[0014]

FIG. 1 is a block diagram of the principle of the present invention, showing a data processing system according to the present invention. This system has a function of connecting a certain system (self system) and another system (communication partner system, hereafter communication partner) through a line or the like, and having a function of transferring a file between them.

To perform this file transfer, for example, a file transfer program 2 and a plurality of application programs 3 are provided on the system side. The file transfer program 2 transfers the file 4 to / from the communication partner 1, and has a function of activating the application program 3. That is, before and after the transfer of the file 4, the application program 3 that executes a process corresponding to the transfer is started from among the plurality of application programs 3.

A plurality of application programs 3 are provided, and each of them performs a predetermined process associated with the transfer of the file 4 and performs different processes. Then, the application program 3 started by the file transfer program 2 performs a predetermined process, which is predetermined by the application program 3, on the file 4 related to the transfer.

[0017]

Before the file transfer, the file transfer program 2 activates one application program 3. The activated application program 3 performs a predetermined process on the transferred file 4 according to the content (transmission, reception) of the transfer. For example, file 4
Delete and create.

After that, the file transfer program 2 transfers the file 4 with respect to the communication partner 1. That is, the file 4 is transmitted or received. After the file transfer, the file transfer program 2 activates one application program 3 again. The started application program 3 determines the transfer result (normal end,
Predetermined processing is performed according to the content of the transfer (abnormal termination) or transfer (transmission, reception). For example, delete file 4, output,
Process and collect.

According to the above, the application program 3 may perform a predetermined process on the file 4 when it is started by the file transfer program 2. Therefore, it is not necessary for the application program 3 to perform the above-mentioned notification of open or the like and various processings each time the file is transferred, so that the load can be reduced. Also,
This eliminates the need for the application program 3 to be aware of the above-mentioned processing such as open, so that the burden for the development can be reduced, and the application program 3 can be developed separately from the file transfer program 2.

[0020]

FIG. 2 is an explanatory view of an embodiment of the present invention.
2A shows the case of transmitting the file A, and FIG. 2B shows the case of receiving the file B.

In FIG. 2A, the file transfer program 2 of its own system receives a reception request (transfer request) of the file A from (the file transfer program of) the communication partner 1. In response to this, the file transfer program 2
Is an application program 3 that performs a process of creating a file 4 in order to create a file A to be transferred.
(Hereinafter, application # 1) is started.

At the time of this activation, the file transfer program 2
Passes the startup information to the application program 3 in order to perform the desired processing on the desired file 4. The activation information will be described later.

The started application # 1 performs the process of creating the file 4 according to the start information to create the file A, and returns (returns) control to the file transfer program 2. In response to this, the file transfer program 2 first returns a response to the previous reception request to the communication partner 1 and transmits the file A to the communication partner 1.

After transmitting the file, the file transfer program 2 requests the deletion of the file 4 in order to delete the transferred file A.
(Hereinafter, application # 2) is started.

The started application # 2 deletes the file A by deleting the file 4 according to the start information, and returns to the file transfer program 2. In response to this, the file transfer program 2 returns a file transfer end notification to the communication partner 1.

In FIG. 2B, the file transfer program 2 receives a transmission request (transfer request) from the communication partner 1 to the file B. In response to this, the file transfer program 2 activates the application # 2 for initializing the file 4 in order to store the transferred file B.

The started application # 2 initializes the file 4 according to the start information, deletes the file B (data thereof), and returns (returns) control to the file transfer program 2.

In response to this, the file transfer program 2
First, the response to the previous transmission request is returned to the communication partner 1, and the file B is received from the communication partner 1. After receiving the file, the file transfer program 2 performs an output process of the file 4 in order to output the transferred file B (hereinafter, application # 3).
To start.

The activated application # 3 outputs the file B according to the activation information, outputs the file B (for example, prints out), and returns to the file transfer program 2. In response to this, the file transfer program 2 returns a file transfer end notification to the communication partner 1.

When the file transfer ends normally, as described above, the file A is deleted on the transmitting side (FIG. 2A) or the file B is output on the receiving side (FIG. 2).
Although processing of the file 4 such as (B) is possible, conversely, if the file transfer itself ends abnormally, the recovery processing of the file A or B is performed.

In this case, the application program 3 (hereinafter, application #
4, not shown) is activated. Launched application # 4
Restores the state before the creation of file A or the deletion of file B.

As described above, a plurality of application programs 3 are provided in advance so that various processes for the file 4 can be performed. The file transfer program 2 selects and starts the application program 3 as needed. For this reason, the file transfer program 2 executes each event related to file transfer (transmission, reception, normal termination, abnormal termination, etc.) and the application program 3 to be started in order to process these (creation, deletion, output, collection, etc.). Holds the relationship with the name in advance.

FIG. 3 shows the start information. Startup information 6
Is information necessary when the file transfer program 2 starts the application program 3, and the application program 3 performs a predetermined process based on this information.

The startup information 6 corresponds to each file 4 and is created by the file transfer environment setting program 7 as the environment information 5 in a predetermined format. Creation of the startup information 6 is independent of whether or not there is a file transfer request.
It is performed prior to the file transfer request (for example, when setting the file transfer environment information).

The environment definition program is started by the user before the file transfer program 2 is started, and stores the input start information 6 in the environment information 5. The environment information 5 includes, for example, file management information, application program management information, and the like.

The startup information 6 is composed of the following information such as a transfer file name. Transfer file name: FILE1 application command start description (start): command name parameter 1 parameter 2 parameter 3 parameter 4 .... parameter n application command start description (end): command name parameter 1 parameter 2 parameter 3 parameter 4. ... Parameter n Transfer file name can be passed: Perform or
Not performed Replacement of replacement file Replacement character string: Transfer process result passability: Perform or
Not performed Replacement of replacement processing result Replacement character string: These pieces of information or the following are set.

Set the file name of the transfer target. Set the activation description of the application command you want to activate immediately before starting the transfer. Of the character string of the application command activation description set in Set the activation description of the application command you want to activate immediately after the transfer ends. Set whether to replace the specified character string part with the transfer file name. Transfer the part of the character string specified in in the application command start description character string set in Set the character string to be replaced with the transfer file name. Set whether to replace with result Set character string to replace with transfer result Startup information 6 defines the operating environment when application program 3 processes file 4. For this,
The file name of is used as a key, and the linked application information of and the file information of are included.

Here, the startup information 6 is created for each file 4, whereas the application program 3 is created for each file format (and / or data format).
For example, as shown in FIG. 3, for files A to M of file format XX, the file format XX is supported 1
A set of application programs 3 is provided. One set of application programs 3 is created by each
App XX that performs processing such as deletion processing, output processing, ...
# 1, XX # 2, XX # 3, ... Further, a set of application programs 3 is similarly provided for the files M + 1 to N of the file format YY.

As a result, one application program 3 does not need to support many file formats (and / or data formats), so that the application program 3 can have a simple structure and can be easily developed.

On the other hand, the start information 6 can be created by the file transfer program 2 by associating the start information 6 with the file 4 independently of the application program 3. As a result, the user does not need to set the startup information 6 for each file transfer (or each time the file 4 is processed accordingly), so that the burden can be lightened.

Since the application program 3 to be started can be designated from the start information 6 and the application program 3 can be made independent of the file transfer program 2, an existing program can be used as the application program 3. That is, since a program for performing the processing is usually prepared for each file 4, this program can be used as the application program 3 of the present invention, and the burden of development can be extremely reduced.

The information of the startup information 6 is the name of the file 4 (for example, "A"), which is set when the file 4 is created, and is used for searching the startup information 6 of the file 4 to be transferred.

The information and the start information 6 are set, for example, immediately before the start and have the format shown in FIG. 4 (A). In FIG. 4A, the command name (application name) is set to the name of the application program 3 to be started (in fact, it also includes a command for starting this).

Predetermined items (for example, the start position and size of the file) are set in the parameters 1 and below as required. In particular, in Parameter 3, a predetermined control character is replaced by (the character string of) the file name of the file 4 to be transferred. For example, “? (? FILE?)” Is used as the predetermined control character. This control character is set as information. This replacement is performed when the file name is set to be delivered by the information. Usually, information is set to be delivered, and information is fixed.

According to this, since it is possible to notify the application program 3 to be started of which file 4 is the transfer target, one application program 3 can handle the processing of a plurality of files 4.

Further, in parameter 5, a predetermined control character is replaced with (the character string indicating) the transfer processing result.
As the predetermined control character, for example, "? (? RTN?)"
Is used. This control character is set as information. This replacement is performed when it is set that information is to be passed as a transfer result. Normally, information is set to be delivered, and information is fixed.

According to this, the transfer processing result can be notified to the application program 3 to be activated, and the processing corresponding to the transfer result becomes possible. In addition, as shown in FIG. 4 (B), parameter 3 (or another parameter)
In the case where a predetermined control character (for example, "#") is set, it may be replaced with the name of the communication partner 1 (for example, the partner PASP of the OSI network).

According to this, since it is possible to inform the application program 3 to be started, which communication destination 1 the file 4 to be processed relates to, it is possible to notify the data to be processed. It becomes possible to perform processing such as data processing in association with the communication partner 1.

5 to 7 are file transfer processing flows. In FIG. 5, the file transfer program 2 waiting for an event causes a file transfer request event for a predetermined file 4 (hereinafter referred to as file A) from the communication partner 1 (step 1).

In response to this request, the file transfer program 2 creates activation information 6 for activating the application program 3 (hereinafter referred to as application # 1) which performs a predetermined process (step 2). Step 2 will be described later with reference to FIG.

The file transfer program 2 is the application # 1.
Is started (step 3), and a state of waiting for recovery from the application # 1 is entered (step 4). Launched application # 1
Performs predetermined processing on a predetermined file A according to the start information 6 and returns to the file transfer program 2.

The restored file transfer program 2 checks whether or not the processing by the application # 1 was completed normally (step 5), and returns normal or abnormal as a response to the file transmission request according to the result (step 6). ..

When it is normal in step 5, the transfer processing of the file A with the communication partner 1 is performed after step 6 (step 7). If it is abnormal in step 5, step 7 is omitted after step 6.

When the file transfer is completed, the file transfer program 2 creates activation information 6 for activating the application program 3 (hereinafter referred to as application # 2) which performs a predetermined process (step 8). Step 8 will be described later with reference to FIG.

The file transfer program 2 is the application # 2.
Is started (step 9), and a state of waiting for return from the application # 2 is entered (step 10). Launched app #
2 performs a predetermined process on a predetermined file A according to the start information 6 and returns to the file transfer program 2.

The restored file transfer program 2 checks whether or not the processing is normally completed by the application # 2 (step 11), and executes the post-processing of the file transfer according to the result, for example, the communication partner reflecting the result. The end is notified to 1 (step 12).

After that, the file transfer program 2 is in a state of waiting for an event (step 13). FIG. 6 mainly shows Step 2, that is, the file transfer program 2 before the file transfer.
The creation processing of the startup information 6 by the is shown.

In FIG. 6, the information of each starting information 6 is searched using the file name "A" (step 14), and the starting information A corresponding to the file A is obtained. The information in the startup information A is checked to determine whether or not the transfer file name can be delivered (step 15).

When delivering, the information of the start information A is checked because it is before transfer, and it is judged whether or not there is a character string designated by the information (step 16). If the character string is present, the designated character string portion is replaced with the file name of the file A (step 17).

If the delivery is not performed in step 15, steps 16 and 17 are omitted. Step 16
When there is no such character string in step, step 17 is omitted. After that, the application # 1 is activated. That is, the start information A
Information is executed (step 3).

FIG. 7 mainly shows step 8 of FIG. 5, that is, startup information 6 by the file transfer program 2 after file transfer.
The creation process of is shown. In FIG. 7, the file name "A" is used to search the information of each startup information 6 (step 18), and the startup information A corresponding to the file A is obtained.

The information in the start information A is checked to determine whether or not the transfer file name can be delivered (step 19). When delivering, the information of the start information A is checked since it is after the transfer, and it is judged whether or not there is a character string designated by the information (step 20).

If the character string exists, the designated character string portion is replaced with the file name of the file A (step 21). When the delivery is not performed in step 19, steps 20 and 21 are omitted. If the character string does not exist in step 20, step 21 is omitted.

Next, the information of the start information A is checked to determine whether or not the transfer result of step 7 can be delivered (step 2).
2). When delivering, the information in the start information A is checked because it is after transfer, and it is judged whether or not there is a character string designated by the information (step 23).

If the character string exists, the specified character string portion is replaced with the file name of the file A (step 24). When the delivery is not performed in step 22, steps 23 and 24 are omitted. If there is no such character string in step 23, step 24 is omitted. After that, the application # 2 is activated. That is, the start information A
Is executed (step 9).

[0066]

As described above, according to the present invention,
In the file transfer process, by causing the file transfer program to start an application program that performs a predetermined process according to the transfer before and after the file transfer, the application program performs a predetermined process, such as open. Since the processing for transfer need not be performed, the load on the application program can be reduced, and the application program need not be aware of file transfer, thus reducing the load on the application program development. Yes, you can use existing programs.
