FIGS. 4 to 7 are examples of the processing flow of the file transfer system according to the present invention, where the environment of FIG. 3 is the processing target and WS-A is the transmitting side and WS-B is the receiving side.

FIG. 4 shows an example of the processing flow of the transmission control program.

The transmission control program is automatically executed after the workstation is started up by utilizing the process generation function of UNIX, and is automatically re-executed after the processing is completed. The transmission control program opens 101 the transmission management file and expands the contents of the transmission management file into the memory 102. Transfer source user name USRA and transmission directory name di in the transmission management file expanded in the memory
Based on rAB, the directory name for transmission is acquired 103 with the complete path name. This causes the sending directory name to be / US
RA / dirAB. After that, it is judged whether or not the file exists in the directory 104, and since the data A exists, the transfer file name is acquired by the complete path name 1
05. The transfer file name at this time is / usra / dirA
B / dataA. After that, create a directory icon to store the file to be transferred when an error occurs.
6. Create 107 a directory icon for storing the successfully transferred file. In order to know the type of the transfer file, which is a document or a general file, additional information acquisition 108 of the transfer file icon is performed. It is determined whether the transfer target file is a document file 109, and when the transfer target file is a document file, the document file transmission program name is set 110 as the child process name. It is determined whether the transfer target file is a general file 111, and when the transfer target file is a general file, the general file transmission program name is set 112 as the child process name. Thereafter, a child process is created 113. In the example of FIG. 3, since dataA is a general file, a general file transmission program name is set and a general file transmission process is generated. After the child process ends, the end code of the process is determined 114, and the end code is 0.
At the time of, copy the file under the transfer successful directory 11
5. Pause 117 the program. Exit code is 0
Otherwise, the file is copied under the error directory 116, and the program is temporarily stopped 117. The transfer control program ends after a pause. Since the transfer control program uses the UNIX process generation function, the transfer control program is re-executed immediately after the process is completed, and the process generation and the process are repeated irrespective of the presence or absence of the transfer file, which puts a load on the workstation. Therefore, by suspending the program for a certain period of time, the load on the workstation is reduced and file transfer is performed at regular intervals.

FIG. 5 shows an example of the processing flow of the general file transmission program.

The general file transmission program uses the transmission control program to transfer the file name to be transferred / URA / dir.
AB / dataA, the receiving side user name USRB, the receiving directory name dirAB, and the receiving side workstation address addrB are passed. Execute the additional information acquisition processing 118 of the transfer file / URA / dirAB / d
The additional information of the icon of ataA is acquired, and the transmission information such as the reception user name USRB, the reception directory name dirAB, the address of the reception side workstation addrB is set in the transfer area 119, and the information of this transfer area is used to set the communication path. The establishment process 120 is performed. When the result of the communication path establishment processing is judged 121, and the communication path is successfully established, the file name additional information transmission processing 123 executes the file name dataA,
Send additional information of dataA and receive successful transmission information 12
After confirming that the receiving program has received the file name addition information in 4, the data transmission process 125 transmits the contents of the file, and the communication channel releasing process 126 releases the communication channel and finishes the process. When the communication path establishing process 120 fails, an error code is set 122 and the post process ends.

FIG. 6 shows an example of the processing flow of the reception control program.

The reception control program is automatically executed after the workstation is started up by utilizing the process generation function of UNIX, and is automatically re-executed after the end of the program. The reception control program opens 127 the reception management file and expands the contents of the reception management file 128 in the memory. It waits 129 for a communication path establishment request from the transmitting side program. When there is a request for establishing a communication path, the communication path is established, and of the destination user name USRB, the transmission directory name dirAB, and the transfer file name dataA sent at this time, the reception management that the destination user name expands first. It is determined whether or not the file is in the file receiving source user name 130, and since there is a name of USRB, the receiving program starting process 131 is performed and the process ends. If there is no user name, an error code is set 132 and the post-processing ends. Since the reception control program uses the UNIX process generation function, it is automatically re-executed after the processing is completed. As a result, the reception control program is always ready to receive a file.

FIG. 7 shows an example of the processing flow of the general file receiving program.

The general file reception program receives the reception source user name USRB, the reception directory name dirAB, and the transfer file name dataA from the reception control program. In the file name / additional information reception process 133, the transfer file name dataA and the additional information of the icon are received, and in the transmission 134 of the reception success information, the general file transmission program is notified that the reception of the file name and the additional information is successful. Perform the received file / icon creation processing 135,
Create a receive file icon of / USRB / dirAB / dataA. Open received file 13
After opening the reception file in 6, the data reception 137 receives the contents of the transfer file in the reception file. After the data reception 137 is completed, it is determined 138 whether all the contents of the transfer file have been received, and when all the contents have been received, the reception file is closed 139. When not all the transfer files have been received, it is judged whether the reception of the transfer files has failed.
0, when reception is unsuccessful, the received file is closed 141, and after the file / icon deletion processing 142 is executed,
After executing the error code setting 143, the process ends. When the reception has not failed, there is the content of the transfer file to be received, so the data is stored 144 and the data reception 137 is performed.

According to the present embodiment, the file / usra / dirAB / dataA under the transmission directory is automatically stored in the reception directory / USRB / dirAB of the workstation on the receiving side, so that the work load of the operator is reduced. , The reliability of work is improved.

[0025]

According to the present invention, when it becomes necessary to transfer a file to another computer, the transfer target file is stored in the area for storing the transfer target file without inputting a command for file transfer. Since the file transfer is automatically repeated just by keeping the setting, there is an effect that the work amount of the worker is reduced and the certainty of the work is improved.
