[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-host logon control system, and more particularly to a multi-host logon control system in a gateway system.

0002

[Prior Art] Conventionally, in a network environment where a terminal device is connected to multiple host computers via a gateway system, in order for a terminal operator to connect to a desired business, it is necessary to specify a business name. It was necessary to specify the host computer.

0003

[Problem to be Solved by the Invention] In the conventional method described above, the terminal operator must always be aware of the correspondence between the business and the host computer that services the business, which places a large operational burden on the terminal operator. There was a problem.

[0004] The present invention aims to eliminate such drawbacks by preparing a correspondence table between tasks and host computers on the gateway system, accepting logon requests from terminal devices by specifying only the task name, and automatically The purpose is to greatly simplify the logon operation of a terminal operator by determining the host computer to be connected and executing the logon procedure.

[0005]

[Means for Solving the Problems] The multi-host logon control method of the present invention provides a network system consisting of a plurality of host computers and terminal devices. A connection management means for managing the correspondence between the host computer and the host computer servicing the business and determining the host computer to be connected to according to the business name requested for connection from the terminal device, and a pair for transmitting and receiving data with the host computer. comprising a host communication means and a business table update means for temporarily changing the correspondence between a business name and a host computer, and when the data received from the terminal device is a logon request, the terminal communication means sends a request. The connection management means determines a host computer to be connected to based on the requested business name, and the host-to-host communication means performs a logon procedure for the determined host computer. The business table updating means temporarily changes the correspondence between the business name and the host computer in accordance with instructions from the console, and specifies only the business name at the time of a logon request, eliminating the need to specify the host computer.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, the multi-logon control method of the present invention includes a terminal communication section 1, a connection management section 2, a host communication section 3, a business table 4, and a business table update section 5.
The terminal-to-terminal communication unit 1, the connection management unit 2, the host-to-host communication unit 3, and the business table updating unit 5 are realized by software running on the central processing unit of the gateway processor 50, and the business table 4 is implemented by the gateway processor. This is realized as an area stored on 50 main storage devices.

FIG. 2 is an explanatory diagram showing the structure of the business table 4.

[0009] Now, when a logon request is made from the terminal device 31 specifying the business name to which the user wants to connect, the terminal communication unit 1 examines the logon request message, extracts the business name from it, and notifies the connection management unit 2. . The connection management unit 2 refers to the business table 4 based on the notified business name, determines the business name and host computer to be connected to when actually performing the logon procedure to the host computer 33, and stores the information. Notice.

The business table 4 is composed of a business name S1, a host logon business name S2, a default host number S3, and a current host number S4. Business name S
1 is the business name used when a logon request is made from the terminal device, that is, the business name that the terminal operator is aware of. The host logon business name S2 is a business name used when a logon request is actually made to the host computer, and may be different from the business name S1. Default host number S3
is the number of the host computer that is servicing the task under normal conditions. The current host number S4 is the number of the host computer currently servicing the business. Default host number S in the initial state
The contents of 3 and the contents of current host number S4 are the same.

[0011] When a logon request is made from the terminal device 31 and a business name is notified, the connection management section 2 searches the business table and finds one that matches the business name S1. Thereafter, by acquiring the corresponding host logon business name S2 and current host number S4, the business name and host computer to be connected to when performing the logon procedure are determined.

Further, the business table updating section 5 rewrites the contents of the current host number S4 in the business table 4. If the operation of a certain host computer is temporarily stopped for some reason, and the work that was being serviced there is temporarily serviced by another computer, the current host number S4 of the relevant work is rewritten from the console 41. This allows the service to continue without affecting terminal operations. Conversely, in order to return to the original state, the contents of the current host number S4 may be updated to be the same as the contents of the default host number S3.

[0013] After the business name and the host computer to be connected are determined in this way when performing the logon procedure to the host computer, the host-to-host communication section 3 implements the logon procedure.

[0014]

[Effects of the Invention] As explained above, the present invention is capable of accepting a logon request from a terminal device and automatically connecting the terminal device in a network environment where the terminal device is connected to multiple host computers via a gateway system. By determining the host computer to be used and performing the logon procedure, the logon operation for the terminal operator can be greatly simplified.
