Abstract

PURPOSE:To automatically maintain a terminal-device side file from the side of a host computer. CONSTITUTION:In the on-line system constituted by connecting one host computer 1 equipped with storage devices 3 and 4 having storage files stored with application programs and data and plural terminal devices 2 through a communication line 10, the storage devices 3 and 4 are provided with control information data bases 32 and 42 and the host computer 1 and terminal devices 2 are equipped with update processing parts 11 and 12. The host computer 1 judges whether or not the terminal-device side storage file 41 needs to be updated and updates the file when so before the execution of a terminal-device side application program, and then executes the application program. Consequently, the terminal devices need not be maintained individually and the host computer and terminal devices can be synchronized at all times.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is directed to a host computer.
Used for collective management of distributed application programs between terminal devices by the host computer. The present invention relates to an online system that can collectively manage maintenance of application programs of online terminal devices from a host computer side.

0002

2. Description of the Related Art Conventionally, maintenance work for online terminal devices has been performed individually for each terminal device.

0003

[Problems to be Solved by the Invention] In such a conventional method, installation work is required for each terminal device, which requires a lot of time for maintenance work. When running a program, it is necessary to constantly synchronize the files used between the host computer and the terminal device, so installation work on all terminal devices takes a lot of time, and the application program becomes unusable for a certain period of time. There was a problem.

[0004] The present invention solves such problems, and aims to provide a system that can collectively manage terminal device files on the host computer side and reduce the time required for maintenance work and installation work. shall be.

[0005]

[Means for Solving the Problems] The present invention provides a system in which one host computer and a plurality of terminal devices are respectively connected via communication lines, and application programs and data are stored in each of the host computer and the terminal devices. In an online system provided with a storage device containing stored files, the storage device includes:
A management information database for managing application programs and data is provided, and each of the host computer and the terminal device automatically determines whether or not the stored file has been updated, and performs update processing by remote control when updating is required. The update processing unit is characterized in that it includes an update processing unit that performs update processing.

[0006]

[Operation] Application programs and data files on the terminal device side are stored in the storage device on the host computer side, a management information database for managing files is provided in the storage devices of the host computer and the terminal device, and the host computer stores the application programs and data files on the terminal device side. Before executing a program, it is determined whether a file needs to be updated, and if necessary, the update is performed and the application program is executed.

[0007] This allows the host computer to collectively manage the files on the terminal device, and automatically updates the files on the terminal device when necessary. Furthermore, synchronization can always be maintained between the host computer and the terminal device.

Embodiments Next, embodiments of the present invention will be explained based on the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In the embodiment of the present invention, one host computer 1 and a plurality of terminal devices 2 are each connected via a communication line 10, and each of the host computer 1 and the terminal devices 2 has a storage system for storing application programs and data. Storage devices 3 and 4 containing files 31 and 41 are provided, and as a feature of the present invention, storage devices 3 and 4 are provided with management information databases 32 and 42 for managing application programs and data, and host computers 1 and 4 are provided with management information databases 32 and 42 for managing application programs and data. Terminal device 2
Each of them includes update processing units 11 and 21 that automatically determine whether or not the stored files 31 and 41 have been updated, and perform update processing by remote control when updating is required.

FIG. 2 is a diagram showing an example of the configuration of the management information database on the host computer side in the embodiment of the present invention. A management database 32 on the host computer side manages information such as an application program name, a terminal device identification name, a terminal device file name, a host computer file name, and an update date.

FIGS. 3A and 3B are diagrams showing an example of the configuration of a management information database on the terminal device side in an embodiment of the present invention. Management information database 42 on the terminal device 2 side
manages information such as file name and update date.

Next, the operation of the embodiment of the present invention will be explained. FIG. 4 is a diagram showing the flow of operation of the embodiment of the present invention.

First, in order to execute the application program "AP1" on the host computer 1, the application program "APT1" on the terminal device 2 side is started. That is, this activation is performed by passing the application program name and necessary data file name from the application program "AP1" to the update processing unit 11 on the host computer 1 side.

Next, the update processing unit 11 on the host computer 1 side searches the management information database 32 to obtain the update date and the file name on the host computer 1 side, and
Send information on the file name and update date to the update processing unit 21 on the terminal device 2 side. The update processing unit 21 on the terminal device 2 side uses the sent information and the management information database 42
Compare the update date above to determine whether an update is necessary■
. If an update is necessary, an instruction is given to the update processing section 11 on the host computer 1 side (2), and the update processing section 11 updates the stored file 31 according to this instruction (2). After all updates have been completed, the update processing unit 11 of the host computer 1 sends an update instruction to the update processing unit 21 of the terminal device 2.
The update processing unit 21 updates the storage file 41 according to this instruction, and updates the application program on the terminal device 2 side.
Start up "APT1"■.

In the case of the terminal device "A01" shown in FIG. 3, the application program "APF1" and the data "DA
TAF1" is updated, and in the case of the terminal device "A02", only the application program "APF1" is updated.

[0016]

Effects of the Invention As explained above, according to the present invention, by collectively managing terminal devices on a host computer, it is possible to automatically update files on the terminal device side at necessary times. There is no need to maintain each device individually, and the host computer and terminal device can always be synchronized.
