Abstract

PURPOSE:To improve a response performance by previously activating a process corresponding to an application program and completing the initialization of the process. CONSTITUTION:Initially, a process initializing and activating means 2 activates the process corresponding to the application program at the time of leading an interactive type processing system to initialize. Thereafter, a process stopping means 3 is activated to temporarily suspend the operating state of the initializing process. Then, a process shifting means 7 refers to process information held by a process information holding means 4 to the activating instruction of the application program from a terminal equipment 11 to shift process swap information in a swap file 12 relating to the corresponding process to a resuming process. Thereafter, a process execution resuming means 8 resumes the execution of the resuming process from the operating state at the time of stopping.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a process control method in a data processing system, and particularly to a process control method in an interactive processing system.

[Conventional technology]

Conventionally, an application program (program such as a distributed processing application program) that runs on a host computer in conjunction with a program on a terminal device is processed under the control of a conversation processing control unit realized by a conversation processing control program, etc. In the process control method of a conversational processing system, when a program is executed as a procedure in which the operating environment such as various resources (memory, central processing unit, etc.) that are necessary for running the program are set, the conversation processing control unit In response to a request to open a conversation processing session by a user of a terminal device, user qualifications (qualifications that determine whether the user is valid for opening a conversation processing session) are determined, and based on that determination, appropriate conversation processing is performed. When the session opening request is authenticated, a conversation processing session is opened based on the authentication, and the conversation processing control unit starts the application program based on an application program startup instruction input by the terminal device user. The corresponding process was started.

In this case, the process of setting up the operating environment specific to the application program, such as initializing work files used by the application program and allocating user files, is always performed at the request of the user of the terminal device to start the application program. It was done later. For example, in an application program that accesses a user file, even if the process is started after the user file is allocated to the application program, operating environment setting processing other than user file allocation is not performed. Even when user files are dynamically accessed and allocated after a process is started, the user files are allocated and accessed after the application program is instructed to start from the terminal device. .

[Problem that the invention seeks to solve]

In the process control method of the conventional interactive processing system described above, the setting process of the operating environment specific to the application program is performed after the terminal device user issues an instruction to start the application program. The initial response time from the host computer to the terminal device in response to a request to start an application program becomes longer. The disadvantage is that it cannot be done.

In view of the above-mentioned points, an object of the present invention is to start a process corresponding to an application program in advance and finish the initialization process (setting process of an operating environment specific to the application program corresponding to the process, etc.) of that process. An object of the present invention is to provide a process control method in an interactive processing system that can shorten the initial response time from a host computer to a terminal device in response to a request to start an application program from a terminal device.

[Means for solving problems]

The process control method in the interactive processing system of the present invention includes a process initial starting means for starting a process corresponding to an application program to perform initialization processing when the interactive processing system is started up, and a process initial starting means for starting a process corresponding to an application program to perform initialization processing. A process stop means that temporarily stops the operating state of a process that has been initialized and outputs process swap information at that point to a swap file, and retains process information of the process stopped by this process stop means. Process information holding means;
In response to an instruction to start an application program from a terminal device, the process information held by the process information holding means is referred to, and based on the reference, information in the swap file regarding the process corresponding to the application program related to the instruction to start from the terminal device is stored. A process transfer means for transferring process swap information to a restart process activated based on a request to open a conversation processing session from a terminal device, and a process corresponding to an application program related to an activation instruction from the terminal device that stops the process. and a process execution resuming means for resuming the execution of the resumed process from the operating state at the time of the stop, where the operating state at the time when the operating state was stopped by the process transporting means was transferred by the process transporting means.

[Effect]

In the process control method in the interactive processing system of the present invention, the process initial starting means starts the process corresponding to the application program to perform initialization processing when the interactive processing system is started up, and the process stopping means starts the process corresponding to the application program and causes it to perform initialization processing, and the process stopping means The operating state of the process that was started and initialized is temporarily stopped, the process swap information at that point is output to the swap file, and the process information holding means stores the process information of the process stopped by the process stopping means. The process transfer means refers to the process information held by the process information holding means in response to an application program startup instruction from the terminal device, and based on that reference, responds to the application program related to the startup instruction from the terminal device. transfers the process swap information in the swap file regarding the process to be executed to the restart process that is activated based on a request to open a conversation processing session from the terminal device;
The process execution resuming means stores the operating state at the time when the process corresponding to the application program for which the startup instruction is issued from the terminal device is stopped by the process stopping means, and the restarting process is performed by transferring process swap information by the process transporting means. Resumes execution from the operating state it was in when it stopped.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an embodiment of a process control method in an interactive processing system of the present invention.
The process control method in the conversational processing system of this embodiment consists of a conversational processing control unit 1, a restart process IO activated based on a request for opening a conversational processing session from the terminal device 11, and a keyboard (not shown). A terminal device 11 that displays a display device (not shown), etc., and processes 91 to 9n.
A swap file 1 in which process swap information (information on memory indicating the operating state of the processes 91 to 9n at the time they are stopped by the process stopping means 3, etc.) is stored.
2, and a plurality of (n (positive integer)) processes 91 to 9n (used corresponding to the same application program) corresponding to a plurality of application programs (not shown) operating under the control of the conversation processing control unit 1. (In some cases, multiple processes with different users are created and started.)

The conversation processing control unit 1 is realized, for example, by a conversation processing control program, and includes a process initial starting means 2, a process stopping means 3, a process information holding means 4, a process holding table 5, a session control means 6, and a process transfer means. The process execution restart means 7 and the process execution restart means 8 are included.

FIG. 2 is a block diagram showing the search process of the process holding table 5 by the process transfer means 7 and the structure of the process information held in the process holding table 5. Referring to this figure, the process holding table 5 is
Process number 101 for each process 91 to 9n. User identification information 102. It holds process information including an application program name 103 and execution restart information 104.

Next, the operation of the process control method in the interactive processing system of this embodiment configured as described above will be explained.

A system file (
(not shown) before a startup command indicating a startup instruction for an application program is input from the terminal device 11 (at the time of startup of the interactive processing system in which the process control method in the interactive processing system of this embodiment is realized) To,
System configuration information given in advance to the conversation processing control unit l (user identification information 102 (in the process holding table 5) that may be input in a request to open a conversation processing session requested from the terminal device 11) Since it is the same information as the user identification information 102 in the process information, it is indicated with the code r102 J.Hereinafter, the same applies to information other than the information in the process information that is indicated with the codes 101 to 104) The process initialization means 2 in the conversation processing control unit 1 processes the process corresponding to each application program based on information including the application program name 103, etc. that may be specified by the startup command input from the terminal device 11. 91 to 9n are started (for individual processes, in the process control method of the conventional conversational processing system, a request to open a conversation processing session is generated from the terminal device 11, and a startup command is input from the terminal device 11. (The same processing would be performed if the

The activated processes 91 to 9n perform initialization processing such as setting their own operating environment, and the process stopping means 3 is called while waiting for communication processing with the terminal device 11.

The process stopping means 3 stores information such as memory contents related to the processes 91 to 9n at that point in time (processes at the time when the processes stopped by the process stopping means 3 91～
9n's operating state) is saved in the swamp file 12 as process swap information, and at that point, the processes 91 to 9n are temporarily stopped and the process information flJ holding means 4 is notified of this. Ru.

The process information holding means 4 stores the process numbers 101 of each of the stopped processes 91 to 9n.

User identification information @102, application program name 103, and program execution restart information tl1104
(Information on the contents of registers (not shown) related to processes 91 to 9n, etc.) is stored in the process holding table 5.

In this state where the processes 91 to 9n are stopped, the session control means 6 in the conversation processing control unit 1 receives a request for opening a conversation processing facility from the terminal device 11 (including the user identification information 102, etc.). The request) is accepted, the restart process 10 is activated based on the request to open the conversation processing session, and the user identification information 102 is
A conversation processing session is opened when the user qualifications are determined based on the following criteria and the request for opening a conversation processing session is verified as valid. (retained and notified to the process transport means 7).

In the open state of the conversation processing facility set in this way, the application name 103 of the specific application program from the terminal device 11 is received via the session control means 6 and the restart process is executed. At IO, the application program name 103 is notified to the process transfer means 7.

The process transfer means 7 selects process information in which the application program name 103 notified from the restart process IO (the application program name 103 of the application program related to the startup command) and the user identification information 102 notified from the session notification means 6 match. A search is performed to see if the processes 91 to 9n in the stopped state in the process holding table 5 are registered as process information.

When the process information of stopped processes 91 to 9n is registered in this search, it means that there is a stopped process corresponding to the application run program related to the start command. Process information (process number 101, user identification information 102, application program name 103, and program execution restart information 104) is extracted, and predetermined process swap information in the swap file 12 is set based on the process number 101 in the process information. 1 of the processes 91 to 9n after being transferred onto the restart process 10
three processes are reproduced on the restart process 10 (one process among the processes 91 to 9n is the restart process lO
).

When the storage of the processes 91 to 9n in one restart process IO is completed, the process transfer means 7 sends information to the process execution restart means 7 indicating that the restart process 10 should be executed (information having the process number 101 and the execution restart information 104). will be notified.

In the process execution restarting means 8, the process execution restarting information 11104 notified from the process transporting means 7 is restored to the restarting process IO, the operation state of the restarting process IO is changed from the stopped state to the operable state, and the restarting process IO is changed from the stopped state to the operable state.
The session control means 6 sets the schedule for the execution of O.
A request is made to cause the request to be made.

The session control means 6 schedules the execution of the restart process IO that has been transitioned to the operable state, and notifies the restart process IO of information regarding the schedule, and the application program related to the startup command input from the terminal device 11. Execution of the process corresponding to (the process realized by the restart process IO) is restarted.

〔Effect of the invention〕

As explained above, the present invention starts a process corresponding to an application program running on an interactive processing system in advance, temporarily stops the process whose initialization processing has been completed, and processes the stopped process. A process that stores swap information in a swap file and, in response to an instruction to start an application program from a terminal device, transfers the process swap information of a stopped process from the swap file to a restart process, and corresponds to the application program related to the start instruction. By restarting the execution of the (resume process), it is possible to omit the processing time required for initializing the process corresponding to the application program after receiving an instruction to start the application program. This has the effect of shortening the initial response time from the host combinator to the terminal device in response to a startup request.
