Abstract

PURPOSE:To enable to offer highly efficient service to many clients by providing a task that makes service of (n) logical circuits to a host by one circuit and an ID control task that controls (n) on-line jobs by the task. CONSTITUTION:When a terminal equipment A1 gives master file renewal request to a host computer, a task 131 receives this, and starts an ID control task 132 when the request message is an ID message. The task 132 searches on-line jobs 133, 134..., and starts empty on-line job, for instance 133, to make it busy state, and processes the message between the task 131. When inquiry request is given from a terminal equipment A2 to the host 13 during file renewal of the job 133, the task 131 starts an ID control task 132. Then, it searches empty on-line job, and starts the job 134, and executes inquiry request processing from the terminal equipment A2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an online processing system between a computer and a terminal.

C. Technical background of the invention and its problems] Conventionally, in this type of online processing method, online processing without general operating system intervention, for example, processing inquiries to a master file managed at the head office, updating at a branch office, etc. Processing such as updating the head office master file with the received data has a one-to-one relationship with the line.

FIG. 4 is a configuration diagram showing an example of a system to which a conventional online processing method is applied. Computers 1.2.3.4 installed at each branch are connected to the host computer installed at the head office via public lines 5.6.7.8, exchange 9, communication control module 10 and modem 11. Connected to job 12.

Now, when a computer 1 at a certain branch sends an inquiry request to the host computer installed at the head office, the request is transmitted via the public line 5, exchange 9, communication control module 1G, and modem 11 to the online telephone. 12. Then, Onlifeji 1bu 12 receives the first I sent from computer 1.
Analyze the D message and determine the function request. This ID
The message is as shown in FIG. 2 (for codes such as '01ζ%021-, the corresponding processing (data part) is determined; in this case) -01#, so the message is online.

The computer 12 processes inquiries from the computer 1.

Similarly, if the ID message sent from the computer 2 to the online job 12 is Hl, the online zip 12 determines that it is a master file update process.In this case, the online zip 12 public line 6,
The host computer at the head office receives data for update processing via the exchange 9, communication control module 10, and modem 11, and when the reception is completed, the line is released and the master file update process in the host computer begins. At this point, online job 12 has temporarily opened the line, but
It is not ready to receive the next process.

For this reason, there is a drawback that it is not possible to provide services to other parties until the online zip 12 completes the processing. To give a specific example of this, in the process of updating the head office master file 711 with data updated at a branch office, the master file is usually updated using the online job 12 after all data has been received. When the amount of data is large, naturally the time dedicated to this processing of the online job 12 becomes long, and therefore, this online job 12 has the disadvantage that it cannot efficiently service a large number of parties. .

[Purpose of the invention]

SUMMARY OF THE INVENTION In view of the above drawbacks, an object of the present invention is to apply an online processing method that can efficiently serve a large number of parties.

[Summary of the invention]

The present invention provides a system in which a plurality of terminal devices are connected to a host computer via a line.
A task capable of providing services for n logical lines on a line, an ID control task that is activated by this task, and n online jobs controlled by this ID control task, and the task When an ID message is received from the device that conveys the details of execution processing for an online job, the ID control task is activated and the activated control task is executed.
The task achieves the above object by adopting an online processing method in which the ID message is passed to a vacant online job and the processing requested by the terminal device by the online job is executed.

[Embodiments of the invention]

An embodiment of the online processing system of the present invention will be described below with reference to the drawings, in which the same parts as those of the conventional example are given the same reference numerals. FIG. 3 is a configuration diagram showing an embodiment of a system to which the online processing method of the present invention is applied. Computers installed at each branch 1.2.3.4 are connected to public lines 5.6.7
．． 8, exchange 9, communication control module 10 and modem 1
1 to a host computer 13 installed at the head office. In the host computer 13, there are tasks 131,
An ID control task 132 and n identical online jobs 133, 134, 135, . . . that are started by the ID control task 132 are provided. In addition, computer 1 has multiple stations (terminal devices).
Up to three units (shown in the figure) are connected.

Next, the operation of this embodiment will be explained. When a master file update request is issued from the stage *7A4 connected to a computer 1 at a certain branch office to the host computer 13 at the head office, this request is sent to the computer 1, the public line 5, the exchange 9, the communication control module 10. The task 131 of the host computer 13 is entered via the modem 11. This task 131 analyzes the input request message, and when the request message is an ID message, starts the ID control task 132, and for other messages, sends the request message directly to the online jobs 133, 134, etc. give. In addition, as a rule for generating the above request message, first
Assume that a D message is sent. The control task 132 is an idle online job 133.
．． 134, 135... and start a vacant online job. At this time, the started online job is placed in a busy state. Subsequent messages are processed between task 131 and the activated online job. In this case, when the online job 133 is activated by the ID control task 132, this online job 133 executes an update process for the master file stored in the computer 13.

While this online job 133 is executing the file update process, an inquiry request is made from the non-stage of the computer 1 to the host computer 13 at the head office via the public line 5, the exchange 9, the communication control module IO, and the modem 11. The inquiry request then enters task 131. Task 131 analyzes the request message and activates ID control task 132. ID control task 132
moves to idle online job search, and starts online job 134, for example, since online job 133 is busy with service with A1 stage users. The online job 134 executes the inquiry request processing from the stage.

According to this embodiment, the task 131 is stored in the host computer 13.
．． By providing a plurality of online jobs 133, 134, 13B, etc. that are started sequentially by the control task 132 and the ID control task 132, the same online job can be executed without complicating the four-judge process of online jobs. It is now possible to operate multiple units in parallel, and to connect to a large number of targets, such as stages, etc.
, etc. can be provided almost simultaneously.

In addition, in the above embodiment, the explanation was given using a public line as an example.
Similar effects can be obtained by applying the present invention to those that use a dedicated line, and online processing is also effective.

〔Effect of the invention〕.

As described above (according to the online processing method of the present invention, a host computer is provided with a task that can service n logical lines with one line, and an ID control task that controls n online jobs by this task). This has the effect of providing efficient services to a large number of customers.
