DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to the application coordinating processor in the file transfer, in particular, the application (user) to process the file transfer program and transfer file application cooperative processing apparatus in the file transfer when linking the program About.

[0002] In order to process a file (transfer file) transferred by a file transfer program, it is usually necessary to link an application program that performs this processing with a file transfer program.

[0003]

BACKGROUND ART FIG. 8 shows an example of a conventional file transfer processing. In this process , the file transfer program 51 provides an application interface 52 to the application program 53, thereby coordinating the two.

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

In this state, when a transfer request from the communication partner (program) 1 of the file transfer is sent to the file transfer program 51, the application program 53 which receives the request via the application interface 52 transmits the request to the file transfer program 51. A file name in the file 4 is checked to perform processing such as data creation for the file 4 to be used as a library, and a 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.

Next, the file transfer program 51 transfers the library (file 4) created by the application program 53 to the communication partner 1, and upon completion of this, notifies the application interface 52
To the application program 53 via the.

The application program 53 checks whether or not the file transfer has been completed normally, performs the processing of the file 4 according to the result, and notifies the file transfer program via the application interface 52 when the processing is completed. 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 of operating the file transfer is essentially a function of the file 4.
There is a problem that the application program 53, which is a program for processing, needs to have.

That is, for one file transfer, the application program 53 sets the open, event,
Notification of transfer start and transfer end must be made each time. In addition, the application program 53 must perform the search of the file name and the processing based on the file name, the investigation of the normal / abnormal termination, and the processing based on the same. Therefore, the load on the application program 53 is large.

[0010] Further, since such processing must be considered by the application program 53, the application program 53 is complicated, and there is a problem that a load for the development is large. Further, there is a problem that the development of the application program 53 must always be performed so as to have contents corresponding to the file transfer program 51.

Note that, apart from the above-mentioned prior art, a file transfer program 51 and an application program 53
As to promote cooperation with, file transfer program 5
1 Start, there is that a process corresponding to the end status to the application program 53 is performed.

[0012] However, even with this thing, application program the ability to run the file transfer 53
In addition, there is a problem that it is difficult to process a plurality of transfers at the same time and it is impossible to operate as a center system.

An object of the present invention is to provide an application cooperation processing apparatus in file transfer in which the load on the application program in the cooperation between the file transfer program and the application program is reduced.

[0014]

FIG. 1 is a block diagram showing the principle of the present invention, and shows a data processing system according to the present invention. In this system, a certain system (own system) and another system (a communication partner system, hereinafter referred to as a communication partner) are connected by a line or the like, and have a function of transferring files between them.

In order to perform the file transfer, for example, a file transfer program 2 and a plurality of application programs 3 are provided in the own system. The file transfer program 2 transfers the file 4 to and 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 performs a process according to the transfer among the plurality of application programs 3 is started.

A plurality of application programs 3 are provided, each of which is 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 that the application program 3 performs in advance on the file 4 related to the transfer.

[0017]

Before the file transfer, the file transfer program 2 starts one application program 3. The activated application program 3 performs predetermined processing on the file 4 to be transferred in accordance with the contents of the transfer (transmission, reception). For example, file 4
Delete and create.

Thereafter, the file transfer program 2 transfers the file 4 to and from the communication partner 1. That is, transmission or reception of the file 4 is performed. After the file transfer, the file transfer program 2 starts one application program 3 again. The started application program 3 executes the transfer result (normal end,
Predetermined processing is performed according to the abnormal termination) or the contents of the transfer (transmission, reception). For example, delete, output file 4,
Perform processing and collection.

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

[0020]

FIG. 2 is an explanatory view of an embodiment of the present invention.
2A shows a case where file A is transmitted, and FIG. 2B shows a case where file B is received.

In FIG. 2A, the file transfer program 2 of the own system receives a file A reception request (transfer request) from (the file transfer program of) the communication partner 1. Accordingly, the file transfer program 2
Is an application program 3 for creating a file 4 in order to create a file A to be transferred.
(Hereinafter, application # 1).

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

The activated application # 1 creates the file A by performing the process of creating the file 4 according to the activation information, and returns (returns) the 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 executes an application program 3 which requests deletion of the file 4 in order to delete the transferred file A.
(Hereinafter, application # 2).

The activated application # 2 deletes the file A by deleting the file 4 in accordance with the activation information, and returns to the file transfer program 2. In response, 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) to the file B from the communication partner 1. In response to this, the file transfer program 2 activates the application # 2 that performs the initialization processing of the file 4 in order to store the transferred file B.

The activated application # 2 performs an initialization process on the file 4 according to the activation information, deletes (data of) the file B, and returns (returns) control to the file transfer program 2.

In response, the file transfer program 2
Returns a response to the previous transmission request to the communication partner 1 and receives the file B 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. The application program 3 (hereinafter, application # 3)
Start

The activated application # 3 performs an output process of the file 4 according to the activation information, outputs the file B (for example, prints out), and returns to the file transfer program 2. In response, the file transfer program 2 returns a file transfer end notification to the communication partner 1.

When the file transfer is completed normally, as described above, the file A is deleted on the transmission side (FIG. 2A) or the file B is output on the reception side (FIG. 2).
(B)) can be processed, but if the file transfer itself ends abnormally, the file A or B is recovered.

In this case, an application program 3 (hereinafter referred to as an application #) for performing a recovery process after the file transfer.
4, not shown) is started. Launched app # 4
Restores the state before file A was created or file B was deleted.

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

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

The start information 6 corresponds to each file 4 and is created by the file transfer environment setting program 7 as environment information 5 in a predetermined format. The creation of the start information 6 is independent of the presence or absence of the file transfer request.
This is performed prior to a file transfer request (for example, when setting file transfer environment information).

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

The start information 6 includes the following information such as a transfer file name. Transfer file name: FILE1 Application command start description (at start): Command name Parameter 1 Parameter 2 Parameter 3 Parameter 4 .... Parameter n Application command start description (at end): Command name Parameter 1 Parameter 2 Parameter 3 Parameter 4. ... parameter n transfer file name transferability: done or
Not performed Transfer file replacement Replacement character string: Transfer result transferability: Performed or
Not performed Replacement replacement character string of transfer processing result: This information or the following is set as follows.

Set the file name of the transfer target. Set the startup description of the application command that you want to start immediately before the start of the transfer. Sets whether to replace the specified character string part with the transfer file name. Transfers the character string part specified in the application command startup description string set in Set the character string to replace with the transfer file name. Set whether to replace with result Set character string to be replaced with transfer result Startup information 6 defines an operating environment when application program 3 processes file 4. For this,
The file name is used as a key, and the associated application information and the file information are included.

Here, the activation 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 the file format XX,
A set of application programs 3 is provided. Each set of application programs 3 is created,
Application XX that performs processing such as deletion processing, output processing, ....
# 1, XX # 2, XX # 3,... Similarly, a set of application programs 3 is provided for the files M + 1 to N of the file format YY.

This eliminates the need for one application program 3 to support many file formats (and / or data formats), so that the application program 3 can have a simple configuration and can be easily developed.

On the other hand, by associating the boot information 6 with the file 4 independently of the application program 3, the boot information 6 can be created by the file transfer program 2. This eliminates the need for the user to set the start-up information 6 for each file transfer (or for each processing of the file 4 associated therewith), and thus the burden can be reduced.

Further, since the application program 3 to be started can be specified 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 development load can be extremely reduced.

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

The information of the start information 6 is set, for example, immediately before the start, and has the format shown in FIG. In FIG. 4A, the command name (application name) is set to the name of the application program 3 to be started (actually, a command for starting the application program 3 is also included).

For parameters 1 and below, predetermined items (for example, the head position and size of the file) are set as necessary. 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. As the predetermined control character, for example, "? (? FILE?)" Is used. This control character is set as information. This replacement is performed when the information indicates that the file name is to be transferred. Normally, the information is set to be delivered and the information is fixed.

According to this, the file 4 to be transferred can be notified to the application program 3 to be started, so that one application program 3 can handle a plurality of files 4.

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

According to this, the result of the transfer processing can be notified to the application program 3 to be started, and the processing corresponding to the transfer result can be performed. As shown in FIG. 4B, parameter 3 (or another parameter)
In this case, when a predetermined control character (for example, “#”) is set, this may be replaced with the name of the communication partner 1 (for example, the partner PASP of the OSI network).

According to this, it is possible to inform the application program 3 to be started which file 4 to be processed is related to the transfer with which communication destination 1, so that the data to be processed and Processing such as data processing associated with the communication partner 1 can be performed.

FIGS. 5 to 7 show the flow of the file transfer process. In FIG. 5, an event of a file transfer request for a predetermined file 4 (hereinafter, referred to as file A) from the communication partner 1 occurs in the file transfer program 2 in an event waiting state (step 1).

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

The file transfer program 2 has the application # 1
Is activated (step 3), and the system is in a state of waiting for a return from the application # 1 (step 4). Launched app # 1
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 by the application # 1 has been completed normally (step 5), and returns normal or abnormal as a response to the file transmission request according to the result (step 6). .

If normal in step 5, after step 6, the process of transferring the file A to / from the communication partner 1 is performed (step 7). If abnormal in step 5, step 7 after step 6 is omitted.

When the file transfer is completed, the file transfer program 2 creates start-up information 6 for starting an application program 3 (hereinafter referred to as an application # 2) for performing 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 the system is in a state of waiting for a return from the application # 2 (step 10). Launched app #
2 performs a predetermined process for 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 has been completed normally by the application # 2 (step 11), and performs post-processing of the file transfer according to the result, for example, the communication destination reflecting the result. 1 is notified (step 12).

Thereafter, the file transfer program 2 enters an event waiting state (step 13). FIG. 6 mainly shows step 2, ie, the file transfer program 2 before the file transfer.
The creation process of the startup information 6 will be described.

In FIG. 6, the information of each piece of activation information 6 is searched using the file name "A" (step 14), and the activation information A corresponding to the file A is obtained. The information of the start information A is checked to determine whether the transfer file name can be transferred (step 15).

When the delivery is performed, the information of the activation information A is checked before the transfer, and it is determined whether or not there is a character string specified by the information (step 16). If there is such a character string, the specified character string is replaced with the file name of file A (step 17).

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

FIG. 7 mainly shows step 8 in FIG. 5, that is, the start information 6 by the file transfer program 2 after the file transfer.
A creation process will be described. In FIG. 7, the information of each piece of boot information 6 is searched using the file name "A" (step 18), and boot information A corresponding to file A is obtained.

The information of the start information A is checked to determine whether or not the transfer file name can be transferred (step 19). When the delivery is performed, the information of the activation information A is checked after the transfer, and it is determined whether or not there is a character string specified by the information (step 20).

If the character string exists, the specified character string part is replaced with the file name of file A (step 21). If the delivery is not performed in step 19, steps 20 and 21 are omitted. If there is no such character string in step 20, step 21 is omitted.

Next, the information of the activation information A is checked to determine whether or not the transfer result of step 7 can be transferred (step 2).
