Referring to FIG. 2, the program information table 23 stores a plurality of entries including a program name, a program size, a device name of an external storage device, and a file name.

Referring to FIG. 3, the process on the side of the transfer source computer 1 of the data transfer time measuring method of this embodiment is performed by the transfer data length, the transfer data number and the transfer destination program name input step 31 and the data reading step 32. An inter-program communication start step 33, a data transfer start time acquisition step 34, a data transfer step 35, a data transfer end time acquisition step 36, a data transfer time display step 37, and an inter-program communication end step 3
8 and.

Next, the operation of the data transfer time measuring method of the present embodiment having such a configuration will be described.

On the transfer source computer 1 side, the operator inputs the transfer data length, the number of transfer data items, and the transfer destination program name from the keyboard 4 (step 3).
1), the input unit 11 inputs the transfer data length, the number of transfer data items, and the transfer destination program name and passes them to the communication request unit 12.

The communication request unit 12 requests the data reading unit 13 to read data using the transfer data length and the number of transfer data items passed from the input unit 11.

The data reading unit 13 reads data of the transfer data length from the data file 5, repeats this for the number of transfer data times, and when the data reading is completed,
The read data is passed to the communication request unit 12 (step 3
2).

When the data request unit 12 receives the data from the data reading unit 13, the communication requesting unit 12 establishes a session between the transfer source computer 1 and the transfer destination computer 2 in order to start inter-program communication. (Step 33).

Upon receiving the session opening request, the communication controller 14 opens a session between the transfer source computer 1 and the transfer destination computer 2.

Next, the communication request unit 12 requests the transfer destination computer 2 to set the association with the transfer destination program 25 via the communication control unit 14 (step 3).
3).

On the transfer destination computer 2 side, when the association setting request is received via the communication control unit 21, the program control unit 22 causes the program information table 23 to read the program size corresponding to the same program name as the transfer destination program name. Get the device name and file name,
Checked whether there is an empty area of the program size in the main memory, whether there is an external storage device with the device name, and whether there is a file with the file name in the external storage device. After that, the program load unit 24 is requested to load the program using the program size, the device name, and the file name.

Upon receiving the program load request, the program load unit 24 can read the transfer destination program 25 having the corresponding program name from the program file 7 and load it on the main memory.

Next, the program control unit 22 activates the transfer destination program 25 by using the transfer destination program name to set an association, and sends a response indicating that the association with the transfer destination program 25 has been set, to the communication control unit 21. To the transfer source computer 1 via.

On the transfer destination computer 1 side, upon receiving a response indicating that the association with the transfer destination program 25 has been set via the communication control unit 14, the communication request unit 12
Notifies the transfer time measuring unit 15 of the start of data transfer.

Upon receiving the data transfer start notification, the transfer time measuring unit 15 acquires the current time as the data transfer start time from the system timer (not shown) of the transfer source computer 1 (step 34).

Next, the communication request unit 12 is connected to the communication control unit 14
To the transfer destination computer 2, and the communication control unit 14 transfers the data read by the data reading unit 13 to the transfer destination computer 2 (step 35).

On the transfer destination computer 2 side, the transfer destination program 25 receives the transferred data via the communication control unit 21.

When the data transfer completion response is received from the communication control unit 14 after the data transfer is completed, the communication request unit 12
The transfer time measuring unit 15 is notified of the end of data transfer.

Upon receiving the data transfer end notification, the transfer time measuring unit 15 acquires the current time from the system timer of the transfer source computer 1 as the data transfer end time (step 36).

Next, the transfer time measuring unit 15 obtains the time required for data transfer (data transfer time) from the difference between the acquired data transfer start time and data transfer end time, and displays the data transfer time. (Step 37).

Subsequently, the communication request unit 12 releases the association with the transfer destination program 25.
Request to the transfer destination computer 2 via (step 3)
8).

On the transfer destination computer 2 side, when an association release request is received via the communication control unit 21, the program control unit 22 terminates the transfer destination program 25 corresponding to the transfer destination program name and releases the association. .

Next, the communication request unit 12 requests the communication control unit 14 to close the session between the transfer source computer 1 and the transfer destination computer 2 (step 38).

Upon receiving the session closing request, the communication control unit 14 closes the session between the transfer source computer 1 and the transfer destination computer 2. This ends the inter-program communication.

In the above embodiment, the case where the transfer source computer 1 and the transfer destination computer 2 are connected in a one-to-one relationship has been described as an example. However, a single or a plurality of transfer source computers 1 and a plurality of transfer destination computers 2 are provided. Even if is connected, the data transfer time can be easily measured by making it possible to specify the computer name of the transfer destination computer 2.

The case where the transfer source computer 1 and the transfer destination computer 2 are connected to one communication line 3 has been described as an example. However, even when the transfer source computer 1 and the transfer destination computer 2 are connected by a plurality of types of communication lines, By making it possible to specify the type of the data, the data transfer time can be easily measured.

[0040]

As described above, according to the present invention, the transfer source computer is provided with the input unit, the data reading unit, the communication request unit, the communication control unit, and the transfer time measuring unit, and the transfer source computer transfers the transfer destination computer to the transfer destination. By enabling the program to be automatically started to perform data transfer, an operator is not required for the transfer destination computer, and thus the data transfer time can be easily measured.

Further, since the transfer data length, the number of transfer data items, and the transfer destination program name can be arbitrarily selected, there is an effect that the data transfer times can be easily compared.

Further, in measuring the data transfer time, since only the time taken for the data transfer is measured, it is possible to eliminate the time taken for the internal processing in the transfer source computer.
