Abstract

PROBLEM TO BE SOLVED: To improve the work switching efficiency and the work switching performance by providing an execution management means, etc., to notify the start, end, interruption or resumption of a program execution means in a prescribed procedure. SOLUTION: When an environment is set, the start or non-start is set for the programs necessary for every task at a start program list storage part 22 of a working environment file 21 of an external storage. At the same time, a notifying object to be interrupted and restarted by the switching of tasks is set at a program start information storage part 23. When the tasks are switched based on the start program list and the program information, only the programs unnecessary for the tasks to be switched are automatically finished. On the other hand, the necessary programs are not finished and only the programs that are short for the tasks to be switched are started. Then the started programs are not started again. Thus the task switching efficiency is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a business processing apparatus and a business processing method, and more particularly to a business processing apparatus and a business processing method for processing business using a workstation and a personal computer. In recent years, work has been diversified with the multi-windowing, and the number of programs required for each work is rapidly increasing. However, the additional memory and the high-speed CPU are expensive ones, and it is required to operate the business with a small memory and a medium-speed CPU.
Therefore, it is necessary to improve the start, end, and switching performance of the work realized by a plurality of programs.

[0002]

Conventionally, as shown in FIG. 9, in the workstation, and a personal computer, once for all program execution means 91 ₁ to 91 _n, to end the execution of the processing by the program, in operations to switch the business switching management unit 92 for managing such an instruction of activation of the required program, had a program execution unit 91 ₁ to 91 _n which operates according to a program.
That is, in the workstation etc. according to the conventional example,
Switching of operations, by the operational switching management unit 92, once the execution of all program execution means 91 ₁ to 91 _n is terminated, it manages to perform an instruction for starting the program required by the newly switched business Was there.

[0003]

As described above, in the business processing apparatus according to the conventional example, when the business is switched, the business switching management means uniformly terminates all programs. By doing so, the program required for the new work is started. Therefore, since a program that is commonly required for a switched job and a switched new job is also terminated and then restarted, there is a problem that the task switching performance may be degraded. Had. Therefore, the present invention intends to improve the efficiency of business switching and the performance of switching by using information indicating an unnecessary program, a necessary program, or a program lacking in the business to be switched for a new business to be switched. It was made for the purpose.

[0004]

In order to solve the above technical problems, the first invention is, as shown in FIG. 1, a program executing means 11 ₁ to 11 for executing processing according to a program.
11 _n and each program execution means 11 ₁ to
A boot program list storage means 13 for storing a boot program list that defines whether or not 11 _n needs to be booted;
On the basis of the program start information storage means 14 for storing information indicating the program execution means 11 _{1 to} 11 _n that needs to be notified of interruption or resumption at the time of business switching, and the start program list and the program start information, It has an execution management means 12 for notifying the program execution means 11 _{1 to} 11 _n of activation, termination, suspension, or resumption in a predetermined procedure.

Here, "starting the program executing means" means setting the program executing means (or the program which is the basis of the operation of the program executing means) in an executable state. For example, as shown in FIG. 7, with respect to the program that is the basis of the operation of the program executing means, after the processing by the OS, the initial processing such as resource acquisition, initialization, and file loading is performed to input the operator's input or other information. To put it in a waiting state for a request from a program.

"Interruption (execution) of program executing means"
The term "stops execution" in the state in which the program execution means (or the program serving as the basis of the operation of the program execution means) is not put into the non-executable end state and the state in which the program execution means can be restored to the ready state is maintained. Say that. For example, as shown in FIG. 7, when a notification is given during the execution of a program for processing a transaction or request, for example, the execution is completed, stopped or frozen, and then restarted. When the notification is necessary, the restart is put in a waiting state so that the later-described program is not terminated. The program to be interrupted is, for example, a program that issues a request to another program, and at the time of business switching, each program does not process a new request, so the program that issues the request To prevent confusion.
In addition, "completion" means completing the processing of the transaction or request being executed, and "stopping" means canceling the processing of the transaction or request being executed without completing it, “Freezing” means that the processing of a transaction or request being executed is suspended midway, and the processing is started from there by a restart notification.

Further, "end (execution) of the program executing means" means stopping the function instructed to the program executing means (or the program which is the basis of the operation of the program executing means). To do the termination,
For example, after performing post-processing such as screen deletion, information update, various I / O close processing or resource release, the end right is declared and the execution right is abandoned, and the resources allocated by the OS are released. To stop the instructed function.
The “predetermined procedure” is a procedure determined according to the contents of the business or program.

The second invention is the same as the first invention.
The execution management means 12 is switched at the time of business switching.
Program execution means 11 unnecessary for new business₁~ 11

Let it. Therefore, in other tasks that have been switched
For necessary programs, please refer to the post-processing and OS processing.
Since there is no need to perform the end process, the switching process is faster.
finish. In addition, the program that did not terminate
Among the execution means, the program execution means to be interrupted is
Notify the disconnection.

When the program execution means receives the interruption notice during the processing of a certain transaction or request, the program execution means can complete, stop, or freeze the processing and wait for the resumption notice. At that time, an operator's input or a request from another program can be held or ignored. When the restart is notified, it becomes possible to restart the operation input by the operator, the request acceptance, or the frozen processing. Further, the programs that are insufficient for the switched jobs are started, but for the programs that are not insufficient, the OS processing and the initial processing of the programs necessary for the startup are unnecessary, and the start of the jobs is accelerated. It will be possible. Therefore, since it is not necessary to uniformly terminate and start the program, it is possible to efficiently and quickly switch the work.

[0010] The third invention is, as shown in FIG. 2, in the first invention or the second invention, the each program execution means 15 ₁ to 15 _n, when there is interruption notification during execution Includes the restart waiting means 16 _{1 to} 16 _n that completes, cancels, or freezes the execution, holds or ignores an operator's input or a request from another program, and waits for a restart notification, and when restart is notified. , Accepting operator input or request, resuming frozen execution, or resuming processing means 17 ₁ to 17 ₁ for processing pending input or request
7 _n . According to the third aspect of the present invention, for a program on which each program executing means relies, at the time of business switching, the best processing can be performed according to the content, so that more efficient and high-speed business switching can be performed. It can be carried out.

A fourth invention is based on the first invention, the second invention or the third invention, wherein the boot program list stored in the boot program list storage means 13 or the program boot information storage means 14 is stored. A dynamic changing means is provided which can change the stored program activation information during system operation. According to the present invention, the boot program list and the program boot information can be dynamically changed without stopping the system. Therefore, the work content can be changed, new work can be added, unnecessary work can be deleted, programs can be changed without stopping the operation of the system, and work efficiency is high.

In a fifth aspect of the invention, in FIG. 3, when there is a task switching instruction (S1), a list of startup programs that determines whether or not it is necessary to start each program for each task, or a task switching procedure In step S2, program start information indicating a program that needs to be notified of interruption or resumption is read out, and a predetermined procedure for a new business switched based on the read start program list and the program start information. Then, while ending unnecessary programs, among the programs necessary for new work,
A program that requires the interruption notification is notified of the interruption, a program lacking in a new task to be switched is activated, and among the activated programs, the program to be resumed is notified of the resumption (S3). That is.

According to a sixth aspect of the present invention, in the fourth aspect, when a program is started and a notice of interruption is given during the processing of the program, the execution is completed, stopped or frozen, and an operator's input or another program is used. Waits for restart notification after suspending or ignoring the above request, and when restart is notified, operator input, acceptance of request, restart of frozen execution, or processing of pending input or request It is to be.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 4, an embodiment of a work processing apparatus using a workstation, a personal computer, or the like according to the present invention is a file provided in an external storage device for storing change items of functions and operability by a user. An operating environment file 21, a line control unit 30 that controls connection of lines, a CPU and a memory 24 that perform various controls related to the business processing apparatus, a display unit 27 that performs various displays, and the business processing. An operation unit 28 that performs various operations such as input to the device, and an output unit 2 that records and outputs the contents processed by the business processing device.
9 is provided.

Further, in the operating environment file 21,
A startup program list storage unit 22 that stores a startup program list that determines whether or not each of the program execution units 26 _{1 to} 26 _n needs to be started for each job, and notification of suspension or resumption when switching jobs It has a program activation information storage unit 23 for storing information indicating necessary program execution units 26 _{1 to} 26 _n .

Further, in the CPU and the memory 24, regarding the designated work, the program executing units 26 _{1 to} 26 _n are activated, terminated, and interrupted in a predetermined procedure based on the activation program list and the program activation information. Alternatively, it has an execution management unit 25 for notifying the resumption. When executing a job change, the execution management unit 25 notifies only the program execution units 26 _{1 to} 26 _n that are unnecessary for a new job to be switched to the end, and the program execution unit 26 ₁ necessary for the new job is notified. of ~ 26 _n, starting notifies the interruption of the execution to the program execution unit 26 ₁ ~ 26 _n requiring interruption notification, the program execution unit 26 ₁ ~ 26 _n missing in a new business to be switched Then, of the activated program execution units 26 _{1 to} 26 _n , the program execution units 26 _{1 to} 26 _n to be restarted are notified of the restart or the synchronization control is performed.

Further, the CPU and the memory 24 are
With user executes processes in accordance with programs required to work, it is started from the execution management unit 25, the notification and instructions from the execution management unit 25, termination, interruption and resumes the program execution unit 26 _{1-26 n}
And an execution control unit 31 that controls the execution of a program by an operating system (OS).

Next, the operation of the work processing apparatus according to this embodiment will be described with reference to FIGS. As shown in FIG. 5, in step S10, as the environment setting, first, in the startup program list storage unit 22 of the operating environment file 21 provided in the external storage device, the programs necessary for performing each job are started. Set the presence or absence of. Further, the program activation information storage unit 23 is set with a notification target of interruption and resumption by switching the business. In step S11,
As shown in the column of the operating environment file in FIG. 6, the execution management unit 25 refers to the startup program list stored in the startup program list storage unit 22 of the operating environment file 21 and is instructed, for example. Program A, program B, program C, ... Required in “Job 1” are activated in this order.

As shown in FIG. 5, in step S12,
A request for switching the business from "business 1" to "business 2" occurs from the host or the like. As shown in the column of the operating environment file in FIG. 6, in the “business 2”, the program A, the program B,
Also, it is necessary to start the programs D, ....

In step S13, the execution management unit 25 refers to the program list stored in the startup program list storage unit 22 of the operating environment file 21, as shown in FIG. Of the programs A, B, and C, the program execution unit 26 ₃ that executes the unnecessary program C in the switched new “business 2” is notified of the end and the process is ended.

Further, of the programs required for the new "business 2" that is read out by reading the program activation information stored in the program activation information storage section 23 of the operating environment file 21, the program B that requires the interruption notice. The interruption is notified to the program execution unit 26 ₂ which executes

For example, the program activation information shown in FIG. 6 indicates that the programs B and C require interruption notice. The program execution units 26 ₁ to 2 2 while processing a transaction or request.
When 6 _n receives the interruption notification, the processing is completed, stopped, or frozen, and the restart notification is waited for. Input from the operator and requests from other programs are ignored. Incidentally, "complete", "stop" and "freeze" are as described above.

In step S14, after the program instructed to end is completed, the execution management unit 25 refers to the activation program list and activates the missing program D in the new "task 2" to be switched. . Further, among the programs A and B which are continuously operating, the restart notification is issued to the program B whose program activation information in the operating environment file is defined as requiring the restart notification.

FIG. 7 shows the progress from the execution management unit 25.
Before, if the ram was started, suspended, resumed, or terminated
OS of execution control unit 31 or program execution unit 26₁~
26 _nThe content of the process of is shown. The execution management unit 25

6_nTo start the program.

Then, the execution control section 31 examines the operation qualifications such as the priority set for each operator in step SO1, and then, in step SO2, the resources necessary for executing the program such as the memory area. Assign Step S
The program is read in O3, and the execution right is assigned to the program in step SO4. The started program execution units 26 _{1 to} 26 _n perform initial processing in step SP1.

In the initial processing, resources such as a memory area necessary for executing the program are acquired, the resources are initialized, records in the file are read, and various I / O can be actually input / output. Environment is set (open processing), and I / O is initialized. After that, there is a process of displaying the initial screen and further examining the usage qualification of the user. Here, the "open process" refers to a process of creating an environment for actually allowing input / output of records in a file (data set). In step SP2, the program execution units 26 _{1 to} 26 _n enter a normal idling state and wait for an input from the operator or a request from another program.

In step SP3, when there is an input from the operator or a request from another program, the program execution units 26 _{1 to} 26 _n execute the processing corresponding to these inputs or requests. In FIG. 7, when the execution management unit 25 gives an instruction to suspend the program in step SE2, the program execution units 26 _{1 to} 26 _n , if the program needs to be restarted, for example, as shown in FIG. In the case of 1, the restart notification is waited for, and the operator's input or the request from another program is suspended or ignored.

If there is no problem in switching the business, an operator's input or a request from another program may be processed. When a "program interruption" is received during the processing of a transaction or request, the processing is completed, stopped, or frozen, and the program requiring the restart notification waits for the restart notification.

For example, according to the program activation information shown in FIG. 6, the interruption notice is given to the program B.
When the end notification is output in step SE4 of FIG. 7, the program execution units 26 _{1 to} 26 _n perform post-processing in step SP6. As for the post-processing, as shown in FIG. 7, the screen is erased, the information in the file and the memory is updated, and various I / O
O close processing is performed.

Here, the "close process" is a process of separating the file (data set) and the application program, which were combined at the time of opening, to bring the control program into the state before opening. Then release the resources. An end declaration is made in step SP7. The end declaration is “exit” in C language, and the execution right is abandoned.

Then, in step SO5, the OS releases the allocated resources, and in step SO6, the OS sends a termination notice to the execution management program. As is clear from FIG. 7, when the interruption process is performed, at the time of restart, the steps SO1 to SO4 and the step SP
It is not necessary to perform the processing of 1. Therefore, when the work is switched, the processing can be started earlier than when the work is started from the beginning when the interruption is performed. In addition, since the program to be continuously executed that is required at the time of business switching is not terminated, step SP6, step SP7,
It is not necessary to perform the processing for ending step SO5 and step SO6, and it is possible to end the processing early at the time of business switching.

FIG. 8 shows the embodiment described above, for example, in each business system in the financial industry (for example,
Among the "account system", "remote maintenance system", ...), the "account system" includes "account", "exchange", "public relations" ... , “Business 3” ... Each job requires one or more programs (control applications), and each program controls various I / Os such as a display unit, a passbook printer, a line connection unit, and an input unit via the OS. It is a thing. Further, in the above embodiment, the boot program list and the program boot information may be dynamically changeable by instructing the execution management unit.

As described above, according to the embodiment of the present invention, when the business is switched, the boot program list stored in the boot program list storage 22 and the program boot information storage 23 are stored. A notification such as termination, suspension or resumption is output based on the stored program activation information. Therefore, by terminating only the programs that are unnecessary for the business to be switched and leaving the necessary programs unterminated, the post-processing and OS processing required at the termination are unnecessary, and the termination processing can be speeded up. In addition, by starting only the programs that are lacking in the task to be switched and not restarting the programs that have already been started, the processing of the OS necessary for starting the programs and the initial processing of the programs become unnecessary,
It is possible to speed up the start of the work, and as a whole, it is possible to speed up the work switching and improve the work switching performance.

[0034]

As described above, according to the first aspect of the invention, the program execution means is started in a predetermined procedure based on the startup program list and the program information,
It ends, suspends, or resumes. Therefore, for example, when switching between jobs, only the programs that are unnecessary for the job to be switched are automatically terminated, the necessary programs are not terminated, and only the programs that are insufficient for the job to be switched are started and started. Since this program does not restart, it is possible to improve the performance or efficiency of business switching. According to the second invention or the fifth invention, at the time of business switching, the necessary program executing means is started in a predetermined procedure based on the starting program list and the program starting information, and the unnecessary program executing means is executed. Is terminated, and the program execution means that needs the interruption notification is notified of the interruption, or the program execution means that needs to be restarted is notified of the restart. Therefore,
Only the programs that are not needed for the task to be switched are terminated, the necessary programs are not terminated, only the programs that are lacking in the task to be switched are started, and the programs that have already been activated are not restarted. You can

According to the third invention or the sixth invention, in the first invention, the second invention or the fifth invention, when each program is notified of interruption during program execution, The process is completed, stopped, or frozen and waits for a restart notification. Therefore, when the business is switched, the business can be switched more efficiently because the interruption can be performed in the best way according to the execution content of each program.

In the fourth invention, it is possible to dynamically change the boot program list or the program boot information. Therefore, the work content can be changed, new work can be added, unnecessary work can be deleted, programs can be changed without stopping the operation of the system, and work efficiency is high.
