Description

Description: BACKGROUND OF THE INVENTION The present invention relates to an online system, and more particularly, to an online system based on routine processing in which a large number of terminal devices and a host computer are connected to each other to perform a routine process. The present invention relates to an online system capable of efficiently processing irregular processing even when irregular processing is mixed in a processing request.

[Conventional technology]

2. Description of the Related Art Conventionally, an online system has a system configuration in which a large number of terminal devices and a host computer are connected, and a host computer processes processing requests from a large number of terminal devices. In an online system, a processing request from a terminal device includes a routine processing and an irregular processing, and a transaction processing method is used for the routine processing.
In the transaction processing method, a terminal device issues a processing request of a small processing unit called a transaction to a host computer. In the transaction processing, processing according to a request is fixedly performed in a space (virtual address space) in which an environment is prepared in advance. In the transaction processing method, the processing request is chopped and fixed in transaction units, and is suitable for routine processing such as, for example, an automatic cash transaction business of a bank system, but is not suitable for irregular processing. .

In an online system, an interactive processing method such as TSS (Time Sharing System) is used for atypical processing. In the interactive processing method, a user's processing request generated from the terminal device generates a new space (virtual address space) in the host computer in accordance with the user's processing request, and analyzes the processing request in that space. Select a program that meets your requirements, assign files,
After performing the OPEN processing of the file and preparing the necessary environment, the selected program executes the requested processing.

In this way, the TSS is suitable for atypical processing because it prepares an environment for performing necessary processing for a processing request, selects a necessary program, generates a processing process, and executes the processing request. However, in response to a processing request from a user, a virtual address space is generated for each processing request, an environment for performing necessary processing is prepared, a necessary program is selected, and a processing process is generated and processed. However, the processing overhead is large and the load on the host computer increases.

[Problems to be solved by the invention]

By the way, in the online system, in the transaction processing method, there is no connection between each terminal device and each specific processing process (space) for performing transaction processing in the host computer, and the specific processing process is performed by a large number of terminal devices. Is performing routine processing of processing requests from. For this reason, the load on the host computer can be reduced, but irregular processing of a processing request from the terminal device cannot be performed freely.

Also, in an interactive processing method such as TSS, a space is generated in the host computer corresponding to the terminal device where the processing request has occurred, a processing process is generated in the space, and processing corresponding to the processing request is performed. Therefore, the atypical processing can be freely performed, but the load on the host computer is increased, and the user must perform an operation for the processing, which causes a problem that the operation is troublesome.

The present invention has been made to solve the above problems.

An object of the present invention is to enable non-standard processing to be mixed in an online system based on standard processing, and to process processing requests for non-standard processing from a terminal device in the same manner as standard processing. And to provide an online system.

The above and other objects and novel features of the present invention are as follows.
It will become apparent from the description of the present specification and the accompanying drawings.

[Means for solving the problem]

In order to achieve the above object, in the present invention, a large number of terminal devices and a host computer are connected via a communication line, and the host computer performs a plurality of processing processes for performing routine processing, and a processing request from the terminal device. And an online control process for transferring control to a predetermined processing process according to the content of the processing request, wherein the online control process generates an atypical processing process space for processing the atypical processing request. A routine processing space generating unit, a unit for determining whether the processing request is a predetermined routine processing request, and when it is determined that the processing request is a predetermined routine processing request by the determining unit, Means for activating the corresponding routine processing process and the determining means determining that the processing request is not a routine processing request Means for generating an atypical processing space by the atypical processing space generating means, calling an atypical processing program in the atypical processing space, and processing the atypical processing request. .

[Action]

According to the above means, in the online system, an atypical processing space generating means for generating an atypical processing space for processing an atypical processing request is provided in the online control process of the host computer. In response to an atypical processing request from a terminal device, the atypical processing space generating means generates an atypical processing space, and executes an atypical processing program for processing the atypical processing request in the atypical processing space. call. Then, the atypical processing program is activated to process the atypical processing request. Accordingly, a user who inputs a processing request from the terminal device can easily execute the processing request processing by the same operation as the standard processing even if the processing request is an irregular processing request.

As described above, when the processing request from the user input from the terminal device is accepted from the terminal device to the online control process on the host computer side through the online control process on the terminal device side, the online control process on the host computer side includes: The processing request from the terminal device is analyzed, and if the processing of the processing request is for a processing process for performing a predetermined process, a predetermined processing process prepared as a standard process is started. Further, if the processing request from the terminal device is an atypical processing that is not prepared in advance, the atypical processing space is generated by the atypical processing space generating means, and the atypical processing process is generated. An atypical processing program corresponding to the processing request is called and activated in the space, and the processing of the processing request is executed.
The processing result of the atypical processing program is sent to the terminal device which issued the processing request by the online control process. The online control process erases the generated atypical processing space when the processing of the processing request ends.

As a result, even if the processing request from the user issued from the terminal device is a processing request of an irregular processing, various irregular processing corresponding to the processing request can be operated by the same easy operation as the routine processing. Can be done.

It is processed.

FIG. 2 is a block diagram illustrating the operation of the online terminal device in FIG. 1, and FIG. 3 is a block diagram illustrating the operation of the host computer in FIG.

Next, the operation of the online system will be described with reference to FIG. 2 and FIG.

In FIG. 2, the online terminal device 1 is provided with a display device 8 and a mouse 9 as an input device for position designation on the display device 8 as input means for a user to input a processing request. Online terminal device 1
The end user in front of the user inputs a processing request by selecting, with the mouse 9, a pictogram called an "icon" displayed on the display device 8, for example. This icon is a picture assigned to each processing object virtualized in the computer. That is, resources such as files and programs in the computer are given meaningful names and are represented by pictures in a form that can be easily understood by the user. For example, data in a table format is stored as a picture on a report sheet. This is a representation of the file that is located. The user operates the display device 8
By identifying an icon representing a file or program desired to be operated from among a plurality of types of icons displayed on the screen, and using a mouse 9, an arrow-shaped cursor on the screen is overlaid on the corresponding icon, An icon selection operation is performed, and a processing request is input to the online terminal device 1.

As described above, the screen control unit 10 displays the icon on the screen of the display device 8 and the user operates the mouse 9 to
When an icon is selected, a selection signal from the mouse 9 is input to the screen control unit 10 in the online terminal device 1 and passed to the request analysis / status management unit 11. Request analysis / status management unit
In 11, which of the processing processes the processing request selected and input by the icon should be processed or can be processed is determined by an icon attribute which is previously developed in a storage device in the online terminal device 1. Search Table 12 and decide. In the icon attribute table 12, the type of the icon 12a and the name of the processing process 12b for executing the corresponding process are registered as a pair. By searching the icon attribute table 12, the processing of the processing request is performed. The name of the process to be executed is required. The request analysis / state management unit 11 activates the standard request generation process 4a that generates a processing request for the corresponding standard processing based on the obtained name. Further, the corresponding atypical request generation process 4b is started. Even in the case of an atypical process that cannot be determined even by searching the icon attribute table 12, the atypical request generation process 4b is started.

The activated request generation process 4 determines the location of the processing target by searching the directory 13 from the name of the processing target such as the file name or the program name obtained from the icon attribute table 12. The directory 13 stores its location as tree-structured data corresponding to the file name and the program name. The directory 13 is located by looking at the upper node 13a corresponding to the node 13b of the target object to be processed in the directory 13. The location (partner processor name: host computer name) is obtained. Here, if the location of the object to be processed is in the online terminal device 1, the processing of the processing request is executed by a processing process (not shown) of the online terminal device 1. If the location is another processor (host computer), the name of the processing process 7 that issues a processing request from the request generation process 4 in the online terminal device 1 is determined. The name of the processing process 7 to which the processing request is issued is stored on the storage device in the online terminal device 1 according to the processing requested by the request generation process 4. When the name of the host computer and the name of the processing process 7 are determined, the request generation process 4 issues a connection request with the target processing process 7 to the online control process 5 on the terminal side. The online control process 5 on the terminal side performs a connection process with a partner processor (host computer) via the communication line 3 based on information defined in advance. After the connection process is completed, the host computer 2
The data in the connection request buffer 14 is transferred.

FIG. 3 is a block diagram illustrating an operation in the host computer 2. In FIG. 3, a connection request and a processing request from the online terminal device 1 are sent to the host computer 2.
An online control process 6 is provided to pass to the standard processing process 7a or the non-standard processing process 7c. The data of the connection request buffer 14 generated and transferred from the request generation process 4 of the online terminal device 1 is first received by the online control process 6. The online control process 6 knows the name of the processing process to be connected from the data in the connection request buffer 14. Online control process 6
When it is determined from the data in the binding request buffer 14 that the processing request is a fixed processing request prepared in advance, the processing data in the binding request buffer 14 is passed to the fixed processing process 7a. The standard processing process 7a is a process that can respond to a specific processing request, and occupies a virtual address space on the virtual storage device. For this reason, the communication control process 6b provided in the online control process 6 searches the process name table 15 and finds out the corresponding standard processing process 7a, and uses, for example, a space communication function (cross memory host). A communication receiving unit 6c for performing communication processing with the online control process 6 in the standard processing process 7a;
Start

On the other hand, if the online control process 6 determines from the data in the binding request buffer 14 that the processing request is an atypical processing request that is not prepared in advance, the online control process 6 executes the online control processing to execute the processing of the atypical processing request. The atypical processing space 7b to be combined is generated and activated by the atypical processing space generating unit 6a provided in the process 6, and the atypical processing The communication accepting unit 6d that performs communication processing with the online control process 6 in the space 7b is activated.

When the communication accepting unit 6c or 6d returns a positive response after checking the processing request, the connection between the request generation process 4 in the online terminal device 1 and the processing process 7 in the host computer 2 is established. After the connection is established, the processing request from the request generation process 4 in the online terminal device 1 is received by the processing process 7 in the host computer 2 in the same manner as the connection with the processing process in the conventional transaction processing. As long as the processing request to the host computer 2 generated in the online terminal device 1 can be processed by the same processing process 7, the connection between the request generation process 4 and the processing process 7 is continued.

The standard processing process 7a is a space in which an environment has been prepared after file allocation and OPEN processing have been completed so as to respond to a specific processing request. The standard processing process 7a can only respond to a specific processing request, but can accept a plurality of requests at the same time and can process requests from many online terminal devices 1 at the same time. Also, for example, a request of a user in front of the online terminal device 1 changes,
If you need the functionality of another standard request processing process,
When the user operates the mouse 9 to select a required processing request by using an icon, the request analysis / state management unit 11 in the online terminal device 1 starts a process corresponding to the selected icon, and performs the processing described above. In accordance with the procedure of the joining process, the joining process with the routine process 7a newly selected in the host computer 2 is performed. The connection by this connection process can be set independently of the previous connection, and the previous connection can be reserved and reused as necessary.
If it is not needed, it is released immediately. Also, in some cases, requests can be generated in parallel using two connections at the same time.

The atypical processing process space 7b is a space in which an environment is prepared so that the atypical processing process 7c capable of responding to an unspecified processing request can operate. The online control process 6 calls an atypical processing program in the atypical processing space 7b and activates the atypical processing process 7c to process any atypical request of the user in front of the online terminal device 1. obtain. For example, when a processing request of a user in front of the online terminal device 1 changes and another atypical processing process becomes necessary, the user operates the mouse 9 and selects a necessary processing request by an icon. Then, the request analysis /
The status management unit 11 accepts the request, sends a processing request by the request generation process 4, calls a newly required atypical processing program, activates the atypical processing process 7c in the atypical processing space 7b, and executes the processing. You can proceed.
When the necessary processing is completed and the atypical processing space 7b becomes unnecessary, it is released immediately, so that the space on the unnecessary virtual storage device is not occupied.

As described above, according to this embodiment, the processing request of the user is analyzed in the online terminal device.
If it is a processing request for routine processing, there is no need to set the environment (file allocation, OPEN processing, table expansion in memory, etc.) in each routine processing process that has been set in advance in the host computer. A plurality of processing requests can be processed by a processing process. For this reason, the number of spaces on the virtual storage device occupied by the routine processing can be limited, and the amount of resources of the host computer can be reduced. As a result, the load on the host computer can be reduced, and the number of online terminal devices that can be connected to the host computer can be increased by an order of magnitude compared to the conventional TSS. It is not necessary to provide a fixed processing process that satisfies the processing request in a specific host computer, and data such as documents and tables of each host computer can be accessed freely and in the same procedure. Further, if the processing request from the user generated from the online terminal device 1 is a request for a routine processing, the routine processing process
7a, if the request is for atypical processing, the atypical processing space is dynamically generated, and various atypical processing processes 7c are operated according to the request. The request can be easily processed by a similar simple operation regardless of the standard processing or the non-standard processing.

As mentioned above, although the present invention was explained concretely based on an example, the present invention is not limited to the above-mentioned example.
It goes without saying that various changes can be made without departing from the scope of the invention.

〔The invention's effect〕

As described above, according to the present invention, the online control process is provided with an atypical space generating means for generating an atypical processing space for the atypical processing, and the online control process performs processing from the terminal device. If it is determined that the request is not a routine processing request, an atypical processing space is generated, control is passed to the atypical processing program, and the atypical processing process is sequentially operated. Can be processed by an easy operation, similarly to the standard processing request.
