Abstract

PURPOSE:To improve the usability and operability of file transfer by specifying file transfer starting time and final file transfer starting time during a file transfer request. CONSTITUTION:At the time of receiving a file transfer request 8 from a file transfer request receiving means 7, a deciding part 82 receives a current date and time from a current time holding part 83 and compares the received contents with file transfer start time 10 included in the request 6. When the specified time 10 has lapsed, the deciding part 82 immediately commands the execution of transfer to a file transfer executing means 9, and when the time 10 has not elapsed yet, saves the request 6 to a temporary hold/transfer request saving part 81 to process another file transfer. Consequently, the usability and operability of file transfer can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to file transfer between host computers, and particularly to execution management of file transfer.

[Prior Art] In this type of conventional file transfer method, file transfer is immediately executed 17 in response to a file transfer request from a user. In addition, if the file transfer cannot be executed immediately, the system will continue to wait until the file transfer can be executed unless the user requests to cancel the file transfer, and the file transfer will be performed as soon as the file transfer becomes possible. It is set to run.

[Problem to be solved by the invention] Such conventional file transfer methods: - Once a file transfer request is received, the file transfer is executed immediately, or if that is not possible, the file transfer is requested by the user. Unless there is a request to cancel, the file transfer is always executed as soon as it becomes possible to transfer the file.For example, if a file transfer is requested during the day and the file transfer is performed late at night when the load on the host computer is low. Because you cannot make a transfer reservation, you may have to request a file transfer at the time when the file transfer is actually required, or you may have to request a file transfer at the desired time due to communication line malfunction, malfunction of the destination host computer, etc. However, if the file transfer is not executed at a certain time, the file transfer will be executed at a time not requested by the user unless the user requests to cancel the file transfer.

The present invention has been made to solve these conventional problems, and its purpose is to improve the operability and operability of file transfer by allowing the user to specify the file transfer start time and final file transfer start time. The aim is to improve

[Means for Solving the Problems] The file transfer method of the present invention is a file transfer method for an information processing system in which a plurality of host computers are connected by a communication line, and a file transfer method for file transfer between host computers. a file transfer request receiving means that sets a file transfer start time and a final file transfer start time in a request and receives the file transfer request in a file transfer execution block on a host computer that executes the file transfer request; The file transfer start time in the transfer request is compared with the current time to determine whether to execute the requested file transfer at the specified time or to temporarily suspend the file transfer execution, and also to start the final file transfer in the file transfer request. The file transfer request determining means compares the time with the current time and cancels the requested file transfer, and the file transfer executing means actually executes the file transfer based on the determination by the file transfer request determining means. are doing.

[Function] By specifying the file transfer start time, you can reserve the file transfer start time.1 Also, by specifying the final file transfer start time, it is possible to reserve the file transfer at a later time than the desired time without having to make a mid-transfer request. I can stop it.

[Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a file transfer method according to an embodiment of the present invention.

A host computer A1 having an external storage device A2 and a host computer O3 having an external storage device color 4 are connected through a communication line. User or host computer A1
When requesting a file transfer between the host computer
is passed to the file transfer execution block 5 in the host computer A1.

In the file transfer execution program 5, the file transfer request receiving means 7 receives the file transfer request 6 from the user and passes it to the file transfer request determining means 8.

The file transfer request determination means 8 compares the current date and time with the file transfer start time lO in the file transfer request 6, and if the current time or the file transfer start time 10 has passed, the file transfer is performed immediately. It instructs the execution means 9 to execute the file transfer, and if the current time has not reached the specified file transfer start time, it temporarily suspends the execution of the requested file transfer until the specified time, and The file transfer request 6 is processed.

Similarly, if the last file transfer start time 11 is specified in the Tsumile transfer request 6, that time is compared with the current year, month, day, and time, and the current time or the specified final file transfer start time is compared. If the start time 11 has passed, execution of the file transfer request 6 is canceled.

The file transfer execution means 9 is the file transfer request determination means 8.
Execute the file transfer commanded from the file on the external storage 91 A2 and the file on the external storage Otsu 4 of the host computer Otsu 3, which is connected to the host computer A 1 via a communication line. do.

FIG. 2 is a block diagram showing the configuration of the file transfer request receiving means 7 of FIG. 1.

The user interface unit 71 receives a file transfer request 6 from the user and passes the request to the transfer request data check unit 72. The transfer request data check section 72
The contents and format of the file transfer request 6 from the user are checked, and if correct, the request is passed to the file transfer request determining means 8, and if it is invalid, the request is passed to the user interface section 7.
1, the user is notified that the request is invalid.

FIG. 3 is a block diagram showing the configuration of the file transfer request determining means 8 of FIG. 1.

Upon receiving the file transfer request 6 from the file transfer request receiving means 7, the determining unit 82 receives the current year, month, day, and time from the current time holding unit 83, and compares it with the file transfer start time 10 in the file transfer request 6. If the specified file transfer start time lO has passed, the file transfer execution means 9 is immediately instructed to execute the transfer, and if the file transfer start time 10 has not yet been reached, the file transfer request 6 is sent to the file transfer request 6. The transfer start time is saved in the temporary pending transfer request saving unit 81, and other file transfer processing is performed.

Further, if there is no file transfer request 6 from the file transfer request receiving means 7, the determining unit 82 determines that the file transfer request 6 is saved in the pending transfer request saving unit 81 when the file transfer start time 10 has passed. If there is a file transfer request 6 that can be executed after the file transfer start time 10 has passed, the file transfer execution means executes the file transfer request 6. Command 9.

However, if the final file transfer start time 11 is specified in the file transfer request 6, it is compared with the current year, month, day, and time obtained from the current time holding unit 83, and the final file transfer start time is determined. If the start time 11 has passed, the execution of the file transfer request 6 is stopped.

FIG. 4 is a block diagram showing the configuration of the file transfer execution means 9 of FIG. 1.

When the file transfer control unit 91 receives a command to execute a file transfer from the file transfer request determining means 8, the file transfer control unit 91 transmits information about the file on the external storage device A 2 to the host computer via the file input/output unit 92 and the communication input/output unit 93. Transfer files to and from Party B3.

[Effects of the Invention] As explained above, the present invention enables a user to specify a file transfer start time and a final file transfer start time during a file transfer request, and also enables the user to specify the file transfer start time and final file transfer start time during a file transfer request. The user has provided a means for executing the requested file transfer based on the start time, determining whether to suspend the requested file transfer, and determining whether to execute or cancel the requested file transfer based on the above-mentioned final file transfer start time. It becomes possible to arbitrarily set the start time and final start time of file transfer.

Therefore, for example, if a file transfer of a huge file is to be performed late at night when the load on the host computer is low, it will be reserved during the daytime.

Alternatively, if there is no point in sending a file after a certain time, you can specify the final file transfer start time, and if the file is not transferred by the desired time, the file will be transferred. This has the effect of improving the operability and operability of file transfer, such as being able to stop the execution of the file transfer without making a new request to stop the transfer.
