DETAILED DESCRIPTION OF THE INVENTION

[Object of the Invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling a form output process that enables a program to be a binder and to improve processing time by performing regular exclusive control in a process of outputting a form by a program. About the law .

[0003]

2. Description of the Related Art Conventionally, in a case where a plurality of tasks for outputting only one form to an output device are executed in parallel in one system, the execution order of form output processing is guaranteed (made as a binder). It is necessary to constantly monitor the state of the task. In addition, in order to guarantee the binder without monitoring the tasks, it is necessary to run the tasks sequentially. According to these conventional methods, there is a problem that a new development of a monitoring task is required or a performance is deteriorated due to sequential processing of tasks.

[0004]

In the above-described conventional form output processing, a monitoring task is required in order to guarantee the order of form output when tasks are executed in parallel, while tasks are sequentially executed. There was a problem that performance was reduced when executed.

The present invention has been made in order to eliminate such a conventional drawback. A plurality of tasks are executed in parallel by one program in response to a form output request to one output device per sheet. A method of controlling a form output process that does not require a monitoring task for guaranteeing the order of form output when performing form output processing, thereby making it possible to convert the form into a binder and improve processing time as viewed from a program. The purpose is to provide the law .

[0006]

In order to achieve the above object, a form output control method according to the present invention is started by a start- up program to execute form creation processing and form output processing.
And execute the first resource before performing the form creation processing.
The first exclusive control is performed using the
Before performing force processing, use the second resource to perform the second
Activating the first and second tasks for exclusive control sequentially
A method of controlling a form output processing for outputting the document Te, before
The first resource used by the first task for the first exclusive control

And a tip .

That is, in the present invention, one system
Start multiple tasks with
To execute the form output process in parallel and finish the process
Then, let each task update its own resources, and
Make regular control to use source
This allows each task to be shut down without using monitoring tasks.
Form output processing is now executed in the order in which they appear in the stem
Therefore, it is necessary to convert the form into a binder and
The processing time can be improved.

[0008]

According to the present invention, a task for outputting a form is generated / started one after another by an activation program requesting output of a form one after another. At that time, one task receives one serial number starting from one. . The task uses the serial number and a value obtained by subtracting 1 from the serial number as resources, and performs exclusive access to those resources to ensure the output order of the form (binding) and improve the performance by parallel processing of the tasks.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a flowchart showing a form output process according to the present invention, and FIG. 2 is a flowchart showing a process of activating a plurality of tasks. First, as shown in FIG.
The activation program 1 issues a first form output request (step S1) to activate the task A, and gives the task A a serial number N (step S2). Immediately after the task A is activated, the first exclusive access is performed using the serial number N as a resource (step S3), and the start program 1 is notified of the exclusive access (step S4). Thereafter, the task A enters a form creation process (step S5), and the activation program 1 issues a second form output request (step S5).
The task B is started by performing 1), and a serial number (N + 1) is given to the task B (step S6). Task B performs exclusive access using the serial number (N + 1) as a resource in the same manner as task A (step S7), notifies startup program 1 of the exclusiveness (step S8), and enters a form creation process (step S8). 9). Since task A has already entered the form creation processing, task A and task B execute processing in parallel.

The resources used for the second exclusive control are as follows:
Task A is (N-1) and task B is N. Since task A and task B are executing in parallel, it is unknown which one will perform the second exclusive access first. If the task A has performed the second exclusive access first (step S10), the process proceeds to the next process of outputting a form (step S11). Conversely, if the task B has performed the second exclusive access first (step S12), since the resource N has already been exclusively accessed by the task A (step S3), until the processing of the task A is completed. Task B enters a waiting state (step S1).
3). Exclusion to the resource n the task A ends is released, the task B resumes, exit the post-processing has been executed output processing of the form a (step S14).

As a result, the form 13 by task A and the form 14 by task B are output to the output device 15 in this order. Of the processing time of the task for outputting a form, the output of the form and the processing for creating the form occupy most of the processing time. Therefore,
Since these can be executed in parallel, an improvement in processing time viewed from the startup program is achieved as compared with sequential processing. In addition, by using a number having regularity, exclusive control between tasks can be easily performed, and the output order of the form can be ensured.

[0012]

According to the control how the form output processing of the present invention as described above, according to the present invention, it is possible to perform the task for outputting a document in parallel, increased processing time as seen from the boot program as compared to sequential processing the can Figure Rukoto. In addition, resource numbers are first assigned to each task from the startup program.
Each task has its resources
Update the report and perform the following processing, so that the output order of the form can be guaranteed without using the monitoring task.
