Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network capable of performing exclusive control of a job generated by a task of each client in a client server system.
A job control method in a work environment.

[0002]

2. Description of the Related Art In each company, a network system such as a server / client system is constructed to facilitate business.

As described above, by using the server-client system, each client machine loads and executes a program installed in the server machine. When the program loaded on the client machine is started, the program is executed unconditionally.

For this reason, while a file provided in the server machine is being updated by a program executed in one client machine, the file is also updated by a program executed in another client machine. Files can be corrupted.

In order to prevent such a situation from occurring, it is necessary for the operator to perform exclusive control of the data file when writing the data file.

[0006]

When the exclusive control of the data file is performed manually by the operator as described above, the data file may be destroyed due to an operator's operation error.

Therefore, without the intervention of an operator,
The only way to perform exclusive control of a data file is to create an application program dedicated to a server machine or a client machine.

However, if an application program dedicated to a server machine or a client machine is created, there is a problem that the work becomes complicated.

The present invention has been made in view of the above points, and an object thereof is to perform exclusive control of a data file by an operation of an operator without creating an application program dedicated to a server machine or a client machine. An object of the present invention is to provide a job control method in a network environment.

[0010]

According to a first aspect of the present invention, in a network environment system including a server and a plurality of clients, a job control method in a network environment is provided. A management file that stores at least the priority of the currently executing job among the jobs generated from the client machine is provided as a shared file, and the client machine refers to the management file when executing its own job. This is a job control method in a network environment characterized by executing a job after recognizing the priority of its own job.

A job management file is provided in the server machine as a management file registered when executing a job generated from the client machine. This work management file stores at least the priority of jobs generated from the client machine.

When a job is generated from the client machine, the job management file is searched for a job that is currently being executed, and whether or not the job is executable is searched. It executes its own job, and if it is not executable, it waits until the currently executing job ends.

OM (read only memory) 22, RAM (random access memory) 23, key input unit 24, LCD
(Liquid crystal display device) 25, FDD (floppy disk device) 26, and printer 27 for issuing a slip are connected.

The RAM 23 stores a program file as shown in FIG.

Next, the structure of a program file will be described with reference to FIG. This program file
Program name A of various slip issuing programs used by office computers 14a to 14c, application program B which is the substance of the slip issuing program, fixed item C
, A file reference path C1, a business level C2 required for exclusive control, and the like are set.

This business level indicates the priority of the application program B by numerical values. For example, if the processing of the program updates the shared file 12a, 0
When a slip is issued based on the shared file 12a, 3 to 5 are set and the shared file 1 is set.
When reference is made to 2a, 6 to 8 are set.

Next, with reference to FIG.
2b will be described. When the program of the client machine 14 becomes executable in the business management file 12b, management information such as a start time, a user name, a system name, a business name, a business level, and a file path is registered. The program is executed.

On the other hand, when the program ends, the management information corresponding to the program is deleted.

Here, the user name is the client machine 14
(14a to 14c), a name indicating which business program of an office computer is to be started is set, a system name is set to the system name, and a business name is a business for issuing, updating, and referring to a slip. A name is set to identify the presence.

Further, the business level stored in the program file shown in FIG. 3 is set as the business level, and the file reference path C1 of the program file shown in FIG. 3 is set as the file path.

Next, the operation of the embodiment of the present invention configured as described above will be described. First, a description will be given of a process performed when a business program among the office computers 14a to 14c of the client machine 14 is selectively executed. When the power of the office computers 14a to 14c of the client machine 14 is turned on, the flow of FIG.
The process shown in the chart is started.

L of the office computer (14a-14c)
In a state where the menu screen as shown in FIG. 6 is displayed on the CD 25, a process of selecting a menu is performed (step S1).

For example, "1. Daily work" is selected from the menu screen a1 displayed on the LCD 25, and by selecting "1. Daily work", "1. Daily work" is selected from the menu screen a2 displayed on the LCD 25 screen. The operation when "2. HISAGO delivery note" is selected will be described.

Here, the program files corresponding to the respective business programs of “1. Concierge... Delivery note” and “2. HISAGO... Delivery note” in the daily work are stored in the RAM 23.

Then, the file reference path C1 of the program file and the business level C2 required for exclusive control are referred to.

The program selected from the menu of the client machine 14 can be executed by referring to the business program level C2 of the program selected from the menu and the currently running business level in the business management file of the shared file 12a. Is determined in the processing after step S2.

Referring to FIG. 5, it is determined whether the currently executed business program set in the business management file and the program selected from the menu are executable. For example, when the job corresponding to the job of the currently executed business program set in the business management file is updated (the business level is 0 to 2), the “reference” of the program (business) selected from the menu is used. Only executable.

When the job corresponding to the currently executed business program set in the business management file is updated (business level is 3 to 5), the “transfer” of the program (business) selected from the menu is selected. Only "issuing (issue of slip)" and "reference" can be executed.

If the job of the currently executed job program set in the job management file is updated (job level is 6 to 8), "update" of the program (job) selected from the menu is selected. Only "transmission (issue of slip)" and "reference" can be executed.

Hereinafter, how the exclusive control of the shared file 12a is performed along the exclusive control relationship shown in FIG. 5 will be described with reference to the flowchart after step S2. First, it is determined whether the business program level C2 of the program selected from the menu is “≦ 2” (step S2).

In the determination in step S2, "YE
S ”, that is, the business level is“ 0 to 2 ”
In the case of, the currently running program is searched from the business management file 12b in FIG. 4 (step S3), and it is determined whether the business level of the currently running program is “0 to 5” (step S4). .

As is apparent from the exclusive control table shown in FIG. 5, the job corresponding to the job selected from the menu is executed when the job level of the currently executing program is "6 to 8" (see). Only possible.

Therefore, if "NO" is determined in the step S4, necessary information is extracted from the program file corresponding to the job selected in the menu and registered in the management information file 12b of the shared file 12a. (Step S5).

Then, the business program is executed (step S6).

On the other hand, in step S4, "YE
If "S" is determined, the file reference path C2 set in the program file corresponding to the job selected in the menu and the file path of the currently executing program set in the management information table 12b are the same. It is determined whether or not it is good (step S7).

If "YES" is determined in step S7, the business program selected from the menu cannot be executed.

On the other hand, if "NO" is determined in the determination in step S7, the processes in steps S5 and S6 described above are performed, and the business program selected in the menu is executed.

By the way, in step S2, "NO"
If it is determined that the operation level C2 of the program selected from the menu is “≦ 5”, it is determined (step S8).

If "YES" is determined in step S8, that is, if the business level C2 is "3 to 5", the processing from step S9 is performed. First, the currently executing program is searched from the task management file 12b of FIG. 4 (step S9), and it is determined whether the task level of the currently executing program is “0 to 2” (step S10).

As is clear from the exclusive control table shown in FIG. 5, the task selected from the menu is possible only when the task level of the currently executing program is "3 to 8" (transmission, reference). Becomes

Accordingly, "NO" in the determination of step S10.
Is determined, that is, the business level is “3 to 8”
For (transmission, reference), necessary information is extracted from the program file corresponding to the task selected in the menu and registered in the management information file 12b of the shared file 12a (step S5).

Then, the business program is executed (step S6).

On the other hand, in step S10, "Y
If "ES" is determined, the file reference path C2 set in the program file corresponding to the task selected in the menu and the file path of the currently executing program set in the management information table 12b are equal. It is determined whether or not it is good (step S7).

If "YES" is determined in step S7, the business program selected from the menu cannot be executed.

On the other hand, if "NO" is determined in the determination in step S7, the processes in steps S5 and S6 described above are performed, and the business program selected in the menu is executed.

On the other hand, if "NO" is determined in the determination in step S8, that is, the business level is "6 to 8" (see).
If it is determined that the information is the required information, the necessary information is extracted from the program file corresponding to the task selected from the menu and registered in the management information file 12b of the shared file 12a (step S5).

Then, the business program is executed (step S6).

As described above, in a network environment system including a server and a client, a job generated from the client is registered in the server and at least the priority of the job is stored. The job management file to be set is set as a shared file, and the client machine executes the job after referring to the job management file and recognizing the priority of the job when executing the own job. Therefore, destruction of data such as a master file stored in the shared file can be reliably prevented without the intervention of an operator.

Further, in each client machine, FIG.
Exclusive control can be performed only by adding a program for performing the processing of the flowchart without creating a business program dedicated to a server machine or a client machine.

In the case of the new business, the three business levels are 0-
Although there is a range such as 2, 3 to 5, 6 to 8, each business level may have a single numerical value. The reason for giving a range to the numerical value indicating the business level is to enable the business level to be changed in the future.
