A condition waiting transfer function for transferring to A and B is provided. Here, the transfer urging unit 1 a is, for example, an application program executed inside the host device 1.

The transfer urging means 1a has a file designating function for designating a file to be transferred to a plurality of server devices A and B. The host device 1 transfers only the file designated by the file designating function from the file 1b. It has a file selection transfer function for selecting and transferring to a plurality of server devices A and B.

In this embodiment, the transfer urging means 1a
Outputs a file transfer command at a preset time, and particularly, at a preset time when the processing load on the host device 1 is low or when the communication load with the server device is low. It is set to output a file transfer instruction. For example, it is a midnight time zone.

The transfer urging means 1a has a function of designating a server to which a file is to be transferred. When receiving the designation of the transfer destination server device from the transfer urging means 1a, the host device 1 selects only the designated server device and transfers the file.

Next, the operation of this embodiment will be described with reference to FIG.

First, a file to be transferred to the server is stored in the file 1b of the host device 1 (S1). This storage may be performed from the operation terminal 3 or may be performed from any server device. When storing this file,
The information of the server device as the transfer destination may be added to the file. Thereafter, when the transfer urging means 1a satisfies the file transfer condition, the transfer urging means 1a outputs a file transfer instruction, information on the server device to be the transfer destination, and information on the designation of the file to be transferred. You. Upon receiving this command, the host device 1 reads the specified file from the file 1b and transfers it to one or more specified destination server devices (S3).
In the present embodiment, the file stored in the host device 1 is transferred to the server device at midnight when the processing load of the host and the communication load with the server device are low.
According to this, efficient file transfer can be performed, and file transfer to the server device can be reliably performed. Here, the server device to be the transfer destination may be the server device specified by the transfer urging unit 1a as described above, or may be the server device specified by the operation terminal 3 or another server device.

Next, another embodiment of the present invention will be described with reference to FIG. The configuration of the system is the same as that of FIG. In the present embodiment, a file is stored in the file 1b of the host device 1 from the operation terminal 3 (S
11). Upon receiving the storage of the file from the operation terminal 3, the host device 1 immediately transfers the file to the plurality of server devices A and B (S12). As a result, file transfer to a plurality of server devices can be reliably performed, and applications of each server device can be updated simultaneously. Here, the transfer destination server device may be designated from the operation terminal 3, and the host device 1 may perform the file transfer only to the designated server device.

Next, still another embodiment of the present invention will be described with reference to FIG. The configuration of the system is the same as that of FIG. In the present embodiment, a command is input from the operation terminal 3 to the host device 1. The host device 1 receives this command input (S21), and determines whether the command is a command to be processed by the host device 1 or a command to be processed by the server device. This determination may be made based on the type of the command, or may be performed based on an identification parameter added to the command. As a result, if it is determined that the command is to be processed by the server device, the command is directly transferred to the server device (S22). Here, in the command input from the operation terminal 3, the server to which the command is transferred may be specified as a parameter. One or more server devices that have received this command process the command, and if the command needs to return a processing result, return the processing result (status) to the host device 1. The commands transferred from the operation terminal 3 to the server device include, for example, a command for returning version information of an application currently stored in the server device, a command for returning system information of the server device, and a command stored in a file of the server device. Prepare commands to execute the application that is being executed.

When the host device 1 receives the status returned from one or more server devices (S23),
The status is transferred to the operation terminal 3 for display output or print output (S24). According to this, for example, a server device that needs to transfer an update file can be easily recognized from the operation terminal 3. Further, the type of the program file to be transferred can be selected according to the model of the server device and the operating system. Furthermore, the update file transferred to the server can be executed from the operation terminal 3 by remote processing, and the application of each server device can be updated at the same time. In addition, it is not necessary to assign a human resource having knowledge on file updating for each store where each server device is located.

[0024]
