Abstract

PURPOSE:To reduce the capacity of a memory by storing a terminal control table regarding a terminal device which makes a connection request newly in place of a terminal control table regarding a terminal device which has made a disconnection request yet. CONSTITUTION:When a terminal 9 sends a connection request to an information processor 1, a table generating means 3 identifies the terminal 9 which has made the connection request according to the address of its terminal sent from the terminal 9 together with the connection request and obtains necessary information from a terminal constitution information file 8 to generate a terminal control table. When a disconnection request receiving means 5 receives a disconnection request from the terminal 9, on the other hand, a table releasing means 7 releases the control table of the terminal 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal control method in an electronic computer system.

〔overview〕

The present invention, in a management means of a terminal device connected to an information processing device, manages the terminal control table of the connected terminal device within a narrow memory area instead of managing the terminal control table of all the terminal devices. This allows the memory capacity required for management to be reduced.

[Conventional technology]

Conventionally, as shown in FIG. 9, a terminal configuration information file is read immediately after a computer is started up, a table for controlling the terminal is created, and processes such as connection and disconnection of the terminal are performed based on the table.

As shown in Figure 1O, the table contains information necessary to control the terminals, such as terminal identification name, terminal type, terminal status, and address, for all connectable terminals 1 to n. [Problem to be solved by the invention] In this conventional control method, a terminal control table must be created for each connected terminal, which has the disadvantage of requiring a large amount of memory. .

The present invention aims to eliminate such drawbacks and provides an information processing device that can reduce the memory capacity required for the terminal control table.

[Means for solving problems]

The present invention is connected to a terminal configuration information file that stores control information including connection disconnection with a plurality of terminal devices and the terminal devices, and a terminal control table created based on control information acquired from the terminal configuration information file. In an information processing device having a memory for storing the terminal control table, the area of the memory for storing the terminal control table is an area large enough to store control tables related to some of the plurality of terminal devices, and The present invention is characterized by comprising a control means for storing a terminal control table related to a terminal device that makes a connection request instead of a terminal control table related to a terminal device that has already made a disconnection request.

[Effect]

When the information processing device receives a connection request from a terminal device, it uses this connection request to create a control table for the information processing device that has issued the connection request, and uses this table to connect to the information processing device that has issued the connection request. , upon receiving a disconnection request from the information processing device connected by the connection means,
In response to this disconnection request, the information processing device that issued the disconnection request is disconnected, and the control table of the disconnected information processing device is released.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the configuration of this embodiment. This embodiment includes an information processing device 1, a terminal configuration information file 8, and a terminal 9. Here, as shown in FIG. 2, the information processing device 1 includes a connection request receiving means 2 that executes a connection request receiving process 21 and a table creation means starting process 22, and a terminal as shown in FIG. A table creation means 3 that executes the steps of identification processing 31, terminal configuration information acquisition processing 32, table creation processing 33, and connection means activation processing 34, and as shown in FIG. 4, disconnection request reception processing 41 and disconnection means activation processing. As shown in FIG. 5, the disconnection request receiving means 5 executes the procedure of 42, the disconnection means 6 executes the procedure of disconnection process 51 and table release means starting process 52, as shown in FIG. It is comprised of a table release means 7 that executes a search process 61 and a table release process 62.

FIG. 7 is a conceptual diagram showing the terminal II child table structure created by the table creation means 3 of FIG. 1, and FIG.
8 is a diagram showing the connection relationship of the terminal control table of FIG. 7. FIG.

Next, the operation of this embodiment will be explained with reference to the drawings. When a connection request is made from the terminal 9 to the information processing apparatus l, the connection request receiving process 21 of the connection request receiving means 2 receives the connection request from the terminal 9, and the table creating means 3 which creates a table for this terminal 9 is sent. The table creation means activation process 22 to be activated is operated. In the terminal identification process 31, the table creation means 3 identifies the terminal 9 that has issued the connection request based on the own terminal address sent from the terminal 9 to the information processing device 1 together with the connection request, and processes the terminal configuration information acquisition process. 32
The information necessary to create a table for controlling the terminal 9 is obtained from the terminal configuration information file 8, and in the table creation process 33, a terminal control table having the structure shown in FIG. 7 is created based on the obtained information. Then, as shown in Fig. 8, the pointers are followed in order from the top pointer of the table chain, and at the end (NULL), the pointer of the table that controls the newly created terminal 9 is assigned, and the chain pointer of the newly created terminal control table is assigned. is substituted with NULL, and the connection means startup process 34 for starting the connection means 4 is operated. The connection means 4 connects the information processing device 1 and the terminal 9 that has issued the connection request.

On the other hand, the disconnection request receiving means 5 receives a disconnection request issued from the terminal 9 to the information processing apparatus 1 in a disconnection request receiving process 41, and operates a disconnection request activation process 42 for activating the disconnection means 6. In a disconnection process 51, the disconnection unit 6 disconnects the information processing device 1 from the terminal 9 that issued the disconnection request, and performs a table release unit activation process 52 in which the table release unit 7 is activated.
make it work.

In the table search process 61, the table release means 7 stores the control table of the terminal 9 that has been cut by the cutting means 6 in the eighth table.
A search is performed in order based on the table chain head pointer shown in the figure, and in table release processing 72, the chain of the control table of the terminal 9 is removed and the control table of the terminal 9 is released.

〔Effect of the invention〕

As explained above, the present invention has the effect of reducing the amount of memory required to control the terminals, even in a large system, because only the terminal control table that is connected is developed in the memory.
