Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a method for managing the types of business processing allowed to each terminal in a data processing system equipped with a plurality of terminals, and in particular, to checking the effectiveness of business processing. The present invention relates to a system in which a business effectiveness table for each terminal is placed in a terminal control device, and business restriction management of each terminal is performed by the terminal control device and a management terminal.

Background of the Technology Generally, in a system such as a banking business, which is composed of a center and a plurality of terminals, each terminal uses a database within the center to execute various business processes.
In order to prevent business confusion and protect data, it is often necessary to prohibit execution by unauthorized operators depending on the type of business processing.

In particular, in systems where each terminal is located in a department, branch, etc. in charge of a specific task, in the above case, it is necessary to create a task effectiveness table that displays the types of tasks that each terminal is allowed to execute. This table is managed by a host computer at the center, and when a business processing request is received from a terminal, the validity is first checked using this table.

Prior Art and Problems Figures 1 and 2 show an example of such a conventional system. Figure 1 is a system configuration diagram, where 1 is the center host, 2 is the communication control unit, and 3 is the system configuration diagram.
4 is a business effectiveness check unit, 4 is a business effectiveness table, 5 is a business processing unit, 6 is a terminal control device T/C,
7-1 to 7-6 are terminal I/O terminals having device numbers #1 to #6, respectively. Also 6′, 6″,…
. . . represents other terminal control devices, and 7', 7'', . . . represent other terminal groups.

The host computer 1 receives business processing requests from each terminal via the communication control section 2, and the business effectiveness checking section 3 refers to the table 4 to check the effectiveness of the business processing. If it is valid, control is passed to the business processing unit 5 to execute the requested business process. On the other hand, if the processing request is found to be invalid as a result of the validity check, an error message is sent to the requesting terminal to inform the operator that the processing cannot be processed from that terminal.

FIG. 2 shows an example of the arrangement of terminals and the contents of the business effectiveness table in the system shown in FIG. 1. In the figure, terminal #1 is assigned for system management and general business processing other than accounting, terminal #2 is assigned for accounting department business, and terminals #3 to #6 are assigned for general business processing other than accounting.

In the business effectiveness table 4, among all the types of business that can be processed from the terminal and all the terminals, the type of business that is permitted to be executed for each terminal is indicated by a circle. (In addition, within the system,
(The business type is represented by a business code, and the terminal is represented by a device number.) For example, console functions such as the use of terminal control commands, center status display, and center control are only allowed for terminal #1, and financial and salary-related work is prohibited for departments other than the accounting department.

In such conventional systems, all business processing requests from each terminal are checked on the host side, so the business effectiveness table for checking is also placed in the host, and it cannot be easily updated. , except for configuration changes such as adding or moving terminals, or changes in department/section attributes, were almost fixed. Therefore, depending on the end user's situation, for example, if the load is concentrated on the terminal of a particular department or department for a certain period of time, for example, and the user wants to perform business processing using the terminal of another department nearby. Therefore, it has been difficult to make detailed changes to terminal business restrictions at any time.

OBJECT AND CONFIGURATION OF THE INVENTION An object of the present invention is to provide a means for easily changing the business restrictions of a terminal according to the situation of the end user on the terminal side of a data processing system. Therefore, the present invention moves the business effectiveness check function from the host to a terminal control device that is easier to control, and makes it possible to update the business effectiveness table from the management terminal. In a data processing system that includes a host computer, a terminal control device, and a terminal device for management or business processing, the terminal control device includes:
A task effectiveness table is provided that displays the types of tasks that are permitted to be executed for each terminal device, and when task processing data is input from the terminal device and a request is made for the task, the type of task requested to be processed is determined. is checked by the above-mentioned business validity table, and if the business is determined to be valid as a result of the check, the above-mentioned business processing data is transferred to the host computer, and on the other hand, if it is determined to be invalid, the above-mentioned business is transferred to the host computer. The present invention is characterized in that a message that cannot be processed is output to the processing request terminal, and that the update of the business effectiveness table is processed in response to a command from the management terminal device.

EXAMPLES OF THE INVENTION The present invention will be described in detail below using examples.

FIG. 3 is a configuration diagram of an embodiment system according to the present invention, FIG. 4 is an explanatory diagram of its operation, and FIG. 5 is a configuration diagram of business effectiveness data. In Figure 3,
1 is a host, 6 is a terminal control device T/C, 7-1 to 7-6 are terminals, 8 is a read buffer for transferring data input from the terminal to the host, 9
1 is a business code table that refers to an address indicating the position of a corresponding entry in the business effectiveness table from a business code, 10 is a business effectiveness table, 11 is a control processor, and 12 is a business effectiveness table updating unit in the host.

The business effectiveness check operation in the terminal control device T/C 6 will be explained with reference to the operation explanatory diagram of FIG.

First, it is assumed that input processing for business use is performed from a certain terminal. This input data is
It consists of a business code and data, and is transferred to the read buffer 8 of the T/C through a line.

The control processor 11 has a read buffer 8
The business code is read out from the input data stored in , and the business code table 9 is searched. When the corresponding business code column is found, the relative value address of the business effectiveness table 10 is extracted from there. On the other hand, if the corresponding business code column cannot be found, an error message "No corresponding business" is output to the terminal.

According to the relative value address of the business effectiveness table 10 obtained from the business code table 9 in step 1, the business effectiveness data regarding the business code is read from the table 10. As shown in an enlarged view in FIG. 5, each bit position of the service effectiveness data corresponds to the equipment number of the terminal, and the value of each bit represents the validity/invalidity of the service for that terminal. Here, the bit value "1" indicates that it is valid.

The control processor 11 checks the value of the bit corresponding to the terminal equipment number in the business effectiveness data,
If it is "1", it is determined that the business is valid and the input data in the read buffer 8 is transferred to the host 1 at the center. Also, if the bit value is “0”, “the corresponding business process is not possible”
Outputs the error message to the terminal.

Next, a method of updating the business effectiveness table will be explained. Normally, in an initial setting process that is performed at the start of system operation every morning, the business code table 9 and the business effectiveness table 10 are set based on master data of the host.

When it becomes necessary to change the content of business restrictions for a certain terminal, the management terminal 7-1 (#1) that can input terminal control commands, that is, the terminal control business is permitted, can be changed as shown in Figure 6. A data input operation as illustrated is performed, and a message is sent to the host 1 at the center. As shown in the figure, the message includes the terminal control command (i.e. business code), table name, equipment number of the T/C to be changed,
It consists of the device number of the terminal to be changed and the change data.

The host 1 decodes this message and uses the business code "999" and "TBL" after the next blank (△ mark) to create a table update message in the business effectiveness table update unit 12 and manage it. After receiving and replying to the terminal 7-1, the updated data is forcibly sent to the corresponding T/C.

According to the received update data, the T/C
Update the corresponding data in the business effectiveness table.

As described above, the contents of the business effectiveness table in any T/C can be easily changed by commands from the management terminal.

Note that the table update process from the management terminal does not update the master data of the business effectiveness table held on the host side. Therefore, at the time of initialization the next day, the T/C business effectiveness table is returned to its previous contents. Furthermore, in this embodiment, the business effectiveness table in the T/C is intended only for subordinate terminals.
The update is then performed only for the T/C associated with the terminal being changed. However, it is also possible to have each T/C maintain a table that targets all terminals in the system, and in that case, updates must also be performed for all T/Cs.

Furthermore, the table can be updated by the management terminal in the target T/C without requesting the host.
Execution may be directly controlled. In this case, tables in other T/Cs cannot be updated.

Effects of the Invention According to the present invention, the business effectiveness table is
Since the setting and updating of this table can be easily controlled by the host, it can be easily done by issuing a table update command from the management terminal to the host using a terminal control command. Update processing can be executed immediately, allowing the end user to use the terminal in a manner that is immediately responsive to the user's situation.

Furthermore, since the terminal business is restricted by the T/C, invalid business processing inputs from the terminal are stopped by the T/C, and the load on the line to the host can be reduced.
