Abstract

PURPOSE:To provide a multi-host system which is highly flexible to the system change and has a reduced number of misoperations by storing the information on the correspondence between the businesses and the host computers in a specific host computer and performing the unitary control of these businesses and host computers. CONSTITUTION:The business-host computer correspondence information is stored in a business-host table 7 of a host 1. A host computer information requesting part 10 requests the host information corresponding to a business to the host 1 through a terminal 5. Thus the host 1 reads the corresponding host information out of the table 7 through a business/host recognizing part 6 and informs the terminal 5 of this host information via a connected host information informing part 8. Then the host 5 is connected to an E business 15 desired by a host 3 through a host connecting part 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-host system, and more particularly, it relates to a multi-host system including a plurality of host computers and terminals for constructing a plurality of jobs.

[0002]

2. Description of the Related Art In a conventional multi-host system consisting of a plurality of host computers and terminals for constructing a plurality of jobs, in order for the terminals to freely access the jobs existing in the system, all hosts must be connected to the terminals. Computer information, such as the business name and network address of the host computer, must be registered in advance, and the user must know which host computer the target business is on. I was consciously performing the connection process with the business.

[0003]

In the conventional multi-host system described above, it is necessary to register the information of all the host computers in the terminal. Therefore, the host computer is added or deleted, or the network address is changed every time. Correspondingly, there is a drawback that it is necessary to change the registration information of the host computers of all terminals and there is little flexibility in changing the system.

Further, since the user has to perform connection processing with the business while being aware of which business exists on which host computer, the user erroneously connects to another host computer and executes the business. There are some cases where it cannot be done, and there is a drawback that there are many mistakes.

An object of the present invention is to store correspondence information between a business and a host computer in a specific host computer,
By performing unified management, it is possible to provide a multi-host system that is highly versatile even when the system is changed and has few malfunctions.

[0006]

A multi-host system of the present invention is a multi-host system consisting of a plurality of host computers and terminals constructing a plurality of jobs, and a specific host among the plurality of host computers. The computer has a storage means for storing correspondence information between the plurality of jobs and the plurality of host computers in which the jobs exist, and a host computer corresponding to the job requested from the storage means in response to a request from the terminal. It is provided with reading means for reading out information and notifying means for notifying the requesting terminal in response to the supply of the host computer information, and the terminal is provided with the host computer information corresponding to a desired job. Requesting means for requesting a specific host computer and a host controller from the specific host computer. In response to the supply of Yuta information is configured to include a connection means for connecting to the corresponding host computer.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a multi-host system of the present invention.

The multi-host system of this embodiment is shown in FIG.
As shown in FIG. 7, in a multi-host system in which seven jobs A to G 17 exist in four host computers from host 1 to host 4, the host 1 which is a specific host computer , A business / host correspondence table 7 storing business and corresponding host computer information, and business / host recognition for accessing the business / host correspondence table 7 in response to a request from the terminal 5 and reading the corresponding host computer information It comprises a section 6 and a connected host information notifying section 8 for notifying the terminal of the supply of the host computer information.

On the other hand, to the terminal 5, a host computer information request unit 10 for requesting host computer information corresponding to a desired job and a host connection for connecting to the host computer in response to the supply of the host computer information from the host 1. And a part 9.

FIG. 2 shows an example of the stored contents of the business / host correspondence table 7. The name of the connection target business, the host name where the business exists, and the network address of the host are stored.

With reference to FIGS. 1 and 2, the operation of this embodiment when the terminal 5 uses the E-work 15 existing in the host 3 will be described.

The terminal 5 is connected to the host 1 and the host computer information requesting unit 10 causes the connection target business name E
The name of the business 15 is sent to the host 1 to request information on the host computer to be connected.

In response to the reception of the request from the terminal 5, the business / host recognizing unit 6 of the host 1 refers to the business / host correspondence table 7 based on the received business name of the connection target, and the corresponding connected host computer information. That is, the connection host name “host 3”, its network address “0003”, and the connection target business name “E” are read and supplied to the connection host information notification unit 8. The connected host information notification unit 8 transmits the connected host computer information supplied from the business / host recognition unit 6 to the terminal 5.

The terminal 5 connects the terminal 5 to the host 3 by the host connecting unit 9 based on the connected host computer information supplied from the host 1 and is the desired job E job 1
5 can be executed.

As described above, in the present embodiment, by providing the business / host correspondence table 7 in the host 1, it is possible to configure a system having a great flexibility by changing only this when changing the system configuration. In addition, it has the effect of reducing erroneous operations.

[0017]

As described above, in the multi-host system of the present invention, the correspondence information between the business and the host computer is stored in a specific host computer, and the centralized management is performed, so that the system can be flexibly changed. This has the effect of increasing the number and reducing the number of erroneous operations.
