Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a large-scale TSS formed by combining a plurality of small-scale TSSs.

(Prior art) In realizing a TSS system, an example of a relatively small-scale system includes multiple control tasks within one job.
One example is one consisting of multiple tasks that correspond one-to-one to the terminal on which the command processor operates. but,
Since this processing structure is established from one job, resources such as the total number of tasks and the number of file assignments are restricted, and it is difficult to apply the above structure to a large-scale TSS that targets multi-terminal connections. For this reason, in conventional large-scale TSSs, as a different approach, it is common to adopt a structure consisting of one control job and a plurality of jobs in one-to-one correspondence with the terminals on which command processors operate. However, the processing structure of this large-scale TSS is similar to that of the above-mentioned small-scale TSS.
This results in an increase in memory due to the difference in the job vs. task structure compared to the processing structure of , and an increase in the number of processing steps due to the difference in job control vs. task control.

(Problem to be solved by the invention) For this reason, when a small number of terminals are in operation, the need for extra memory capacity and processing overhead will not result in mass sales, but in a large-scale TSS, it will actually work. It is not possible to realize an optimal system according to the number of terminals, and there is a drawback that different approaches must be taken for small-scale TSS and large-scale TSS.

An object of the present invention is to eliminate the above drawbacks by combining a plurality of small-scale TSSs realized for connecting a small number of terminals, and to realize a large-scale TSS without modifying the processing method. The object of the present invention is to provide a method for constructing a large-scale TSS configured to optimize resources.

(Means for solving the problem) The construction method of a large-scale TSS according to the present invention is
It is configured to include an SS, session management table means, and management job means.

Each of the plurality of small-scale TSSs is realized to connect a small number of terminal devices.

The session management table means is for managing terminal connection status of a plurality of small-scale TSSs.

The management job means is for controlling terminal connections to a plurality of small-scale TSSs by means of a session management table means, and also for controlling operation management commands of the center.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a configuration diagram showing an embodiment of a small-scale TSS which is an element constituting the large-scale TSS construction method according to the present invention. In FIG. 1, 1 is a small-scale TBS, 2 is a main task, 3 is a terminal input task, 4 is a terminal output task, 5 is a plurality of command processing tasks, 6 is a system control console, and 7 is a plurality of terminal devices. .

In FIG. 1, when a connection to the TSS is requested from the terminal device T, the terminal input task 3 executes the command processing task 5.
Allocate unused ones to the corresponding terminal. Thereafter, commands and data input from the terminal device T are passed through the terminal input task 3 to the corresponding command processing task 5.
The results processed by the command processing task 5 are displayed on the terminal device 7 through the terminal output task 4. Also, T.S.
When a command for operational management of service termination of S is input from the system control console 6, the main task analyzes it and performs processing according to the command.

Figure 2 targets a small number of connected terminals as mentioned above.
FIG. 2 is a configuration diagram showing an embodiment of a large-scale TSS according to the present invention, in which a plurality of small-scale TSSs constructed by a task structure within one job are combined. In FIG. 2, 1 is a plurality of small-scale TSSs, 6 system control consoles, 7 terminal devices, 8 is a management job, and 9 is a plurality of session management tables.

FIG. 3 is a configuration diagram showing an example of the management job 8 in FIG. 2. In FIG. 3, 6 is a system control console, I is a terminal device, 8 is a management job, 10 is a main task, 1
1 is a terminal connection control task. Figure 4 shows each small-scale T
FIG. 3 is a configuration diagram showing details of a plurality of session management tables 9 corresponding to SS. Each session management table contains information on whether the corresponding small-scale TSS is in operation, the maximum number of connectable terminals, the number of currently connected terminals, and information on whether the corresponding small-scale TSS is currently in use. It manages information such as the terminal name used by each user, user name, and group name.

In this large-scale TSS, when there is a connection request to the TSS from a terminal device, the terminal connection control task 11 of the management job 9 receives all the connection requests. In order to equalize the load on each small-scale TSS, the terminal connection control task 11 sequentially checks the information on the maximum number of connectable terminals and the number of connected terminals in each session management table, and checks the current number of small-scale TSSs that can still connect. Terminal connections are switched to the small-scale TSS with the least number of connected terminals. For example, three small-scale TS
S is running and the maximum number of connected operating terminals is 20.
Terminal, the number of currently connected terminals is small TSS1-1
Assume that there are 15 terminals for small-scale T881-2, 18 terminals for small-scale TSSI-3, and 17 terminals for small-scale TSSI-3. When a connection request is received from a terminal in this state, the management job switches the connection to the small TSS 1-1. Through this terminal connection switching, the small-scale TSS operates as if a connection request had been made directly from the terminal, and from then on, processing is performed as a single small-scale TSS independently of other small-scale TSSs according to the method explained in Figure 1. move on.

Each entry consisting of the number of connected terminals, terminal name, user name, and group name in the session management table corresponding to each small-scale TSS is counted up, down, or set/
Reset.

On the other hand, the operation management command input from the system control console 6 is received and analyzed by the main task 10 of the management job. Among these, commands that target all terminals, such as termination of TSS service, are notified to all small-scale TSSKs.

Further, a command targeted at a specific terminal user sequentially searches the session management table of each small-scale TSS, and is notified to the small-scale TSS to which the terminal is connected.

The small-scale TSS that receives this notification performs the same processing as when operating independently.

As mentioned above, by running multiple small-scale TSSs that can operate independently under a management job, large-scale TSSs can be
is constructed. In the conventional method, the processing of one terminal corresponds to one job, but in the method of the present invention, the processing of one terminal corresponds to a task, so it is possible to reduce memory by job versus task and control jobs versus tasks. The number of processing steps can be reduced through control. Furthermore, in implementing the system, the method of the present invention can be applied to small-scale TSSs, and the configuration is simpler than that of conventional systems.

(Effects of the Invention) As explained above, the present invention provides a
By increasing the number of small-scale TSSs that operate simultaneously, the number of connected terminals can be easily expanded, and a large-scale TSS having optimal system resources according to the number of terminals can be realized.
