Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system in which a management computer and a plurality of business computers are connected by a transmission line, and more particularly, the management computer uses each business computer for business purposes. The present invention relates to a data distribution device of a computer system that distributes data.

[0002]

2. Description of the Related Art For example, as shown in FIG. 6, a client / server system constructed on a network such as a LAN constructed in a company has a plurality of clients 1 as business computers and one client computer as shown in FIG. A management server 2 as a management computer is connected via a transmission line 3.

Then, each client 1 executes various kinds of work based on a work program stored in its own storage unit. The type of work performed by each client 1 may be the same for all clients 1 or may be different for each client 1.

Since the business program stored in each client 1 is frequently changed as needed, the program is not individually changed for each client, and each program is changed from the management server 2 via the transmission line 3 to each client. The business program is distributed to the client 1.

In this case, when a program is distributed from the management server 2 to each client 1 and the program stored in the storage unit of each client 1 is rewritten, it is possible to change the state in which the work using the program is not executed. Must be maintained. The reason for this is that if the program is rewritten during execution, there is a risk that an abnormal value will occur in the business process result or abnormal stop will occur.

However, since each client 1 executes its work at an independent timing, the management server 2 monitors the execution state of the program to be rewritten by each client 1 and executes the program during the period when it is not executed. It is very complicated to distribute and rewrite.

In order to avoid such an inconvenience, the operator operates the management server 2 by using the remote shell function and sends a command to terminate the work using the corresponding program to the client 1. The work of the client 1 is manually ended, and in that state, the program is distributed and the program is updated.

Further, when the program distribution to each client 1 is completed, the operator again uses the remote shell function to operate the management server 2 to restart the work of the client 1 by manual operation. .

[0009]

However, each time a program is distributed from the management server 2 to each client 1, as described above, the operator uses the management server 2 to manually operate each program. It is very complicated for the operator to control the state of each client 1 by transmitting a command to end each job and a command to start the job to the client 1.

For example, if the operator has forgotten to operate the job start command, the operator of the client 1 cannot execute the job. Further, some programs distributed by the management server 2 to each client 1 require environment conditions and environment settings specific to each program. After distributing the program to the designated client 1, complicated operations are executed. However, it is necessary to manually perform the above-mentioned environmental conditions and environment settings, which not only significantly increases the operational burden on the operator, but also may cause human error. Moreover, the work efficiency of program distribution is significantly reduced.

The above-mentioned problems can be said not only in the case of distributing program data for business but also in the case of distributing various fixed data such as parameters used in business. Further, the same can be said when rewriting the searched data registered in the database formed in the client 1.

The present invention has been made in view of such circumstances, and it is necessary to prepare in advance a pre-processing and a post-processing to be executed before and after the distribution of various data used for business to each business computer. As a result, the operator only needs to input a data distribution command to the management computer, and the pre-distribution and post-distribution processing is automatically executed on the business computer, greatly reducing the operator's operational burden and distributing the data. It is an object of the present invention to provide a data distribution device for a computer system, which can improve work efficiency and further suppress the occurrence of human error, thus improving the reliability of the entire system.

[0013]

In order to solve the above-mentioned problems, the present invention provides a plurality of business computers for performing various business using data stored in a storage unit and a management for managing the plurality of business computers. Of a computer system that distributes data from the management computer to each business computer and updates the data stored in each business computer in a computer system that is connected to each other via a transmission line In the data distribution device, in response to a data distribution request from the management computer, pre-processing execution means for automatically executing the distribution pre-processing required for updating the stored data in each of the distribution-destination business computers, and the pre-processing. Depending on the end of the pre-distribution process of the execution means, send the data to the distribution destination business computer,
Data distribution means for updating the data in the storage unit with the distributed data, and distribution necessary for resuming various business operations using the stored data on the distribution destination business computer depending on the completion of the data updating by the data distribution means. And a post-processing executing means for automatically executing the post-processing.

In the second aspect, the data in the data distribution device of the computer system of the invention is a business program, and the pre-distribution processing is a business using the program stored in the storage unit. Work termination means for forcibly terminating, and program saving means for writing the stored program in the buffer area after this termination are included.

Further, the data distribution means determines whether or not the data in the storage section has been updated normally, and the original program saved in the buffer area in the storage section if the data has not been updated normally. And a program restoring means for writing.

Further, in claim 3, the storage unit of the business computer in the data distribution apparatus of the computer system of the invention described above is a database, and the pre-distribution processing prohibits the search business for the data stored in the database. Including search prohibition means. Further, the post-distribution processing includes a search prohibition canceling means for canceling the prohibition of the search operation on the data stored in the database.

In the data distribution device of the computer system thus configured, for example, when the operator inputs a data distribution request to the management computer, the corresponding data is distributed to the business computer via the transmission line. Before that, the distribution-destination business computer automatically executes the pre-distribution processing necessary for updating the stored data. Then, after that, the data is distributed from the management computer, and the data in the storage unit of the business computer is updated to the distributed data. Further, after the data update processing is completed, post-distribution processing necessary for restarting the work is automatically executed.

Therefore, the operator does not need to manually perform the pre-distribution processing and the post-distribution processing as in the conventional method, so that the data distribution work efficiency is improved. In the data distribution device according to the second aspect, a business program is assumed as the data to be distributed.

In this case, when the pre-distribution process is started, the work using the program is forcibly terminated. In addition, the program stored in the storage unit is saved in the buffer area. If the distributed program does not normally update the data in the storage unit, the original program saved in the buffer area is written in the storage unit.

Therefore, even if an abnormality occurs in the update of the program, the operation can be resumed with the program before the update for the time being, and the obstacle range of the operation can be suppressed to the minimum. In the data distribution device according to the third aspect, a database is assumed as the storage unit of the business computer.

In this case, when the pre-distribution process is started, the data retrieval operation for the database is prohibited. Then, when the data update of the database is completed, the prohibition of the search operation is released, and the search operation for the updated database is restarted.

In the program memory 25, a program area 28 for storing a business program and an evacuation buffer area 29 for temporarily storing the business program are stored.
Are formed. Furthermore, this program memory 25
If necessary, a pre-distribution processing program 30 and a post-distribution processing program 31 are stored therein.

In the initial state, each program is not stored in the program memory 25, and if necessary, a program for business use, a pre-distribution program 30 and a distribution program from the management server 13 via the transmission path 11. The post-processing program 31 is written.

Next, a processing procedure for distributing the business program from the management server 13 to each client 12 will be described. First, the management server 13 stores the pre-distribution processing program 30 and post-distribution processing stored in the data memory 18 or input from the outside before actually starting the processing of distributing the business program to each client 12. The program 31 is transmitted to each client 12 via the transmission / reception unit 19 and the transmission path 11.

The CPU 22 of each client 12, which has received the pre-distribution processing program 30 and the post-distribution processing program 31 by the transmission / reception unit 27, programs the received pre-distribution processing program 30 and post-distribution processing program 31 according to the management program of the program memory 24. Write in memory 25.

Since the writing processing of the pre-distribution processing program 30 and the post-distribution processing program 31 does not affect the business executed by the business program stored in the program area 28, the business processing is performed. Is executed without being terminated or interrupted.

Unless the specifications of the business program stored in the program area 28 are significantly changed, the pre-distribution processing program 30 and the post-distribution processing program 31 are executed every time the normal specifications of the business program are changed. No need to change.

While the pre-distribution processing program 30 and the post-distribution processing program 31 are written in the program memory 25 of each client 12, they are temporarily stored in the data memory 18 to one client 12 designated by the management server 13. The distribution process of the distribution program 20 will be described with reference to the flowcharts of FIGS.

2 is a flow chart showing the operation of the management server 13, and FIG. 4 is a flow chart showing the operation of the client 12. When the operator inputs a program distribution command designating the distribution destination client 12 and the distribution program 20 to the management server 13, the management server 13 sends the distribution destination client 12 in P1 of FIG.
Send the pre-distribution execution command to.

The distribution destination client 12, which has received the distribution preprocessing execution command from the management server 13 in Q1 of the flow chart in FIG. 3, executes the distribution preprocessing according to the distribution preprocessing program 30 in the program memory 25 in Q2 and Q3. To execute.

That is, the work being executed is terminated according to the program stored in the program area 28.
When the work is transferred to the end state, the current program stored in the program area 28 is written in the buffer area 29. Then, in Q4, the execution result of the pre-distribution process is transmitted to the management server 13.

The client 12 of the distribution destination at P2 in FIG.
The management server 13 that has received the execution result indicating that the pre-distribution process has normally ended transmits the distribution program 20 temporarily stored in the data memory 18 to the corresponding client 12.

The distribution destination client 12 that has received the distribution program 20 from the management server 13 in Q5 of FIG.
Writes the distribution program 20 in the program area 28 of the program memory 25 in Q6. When the program is normally written (Q7), the version of the newly written program is compared with the version of the previous program saved in the buffer area 29 (Q8). Then, it is confirmed that the version of this program is larger than the version of the previous program (Q9). When the confirmation of the version is completed, a normal writing completion notification is transmitted to the management server 13 (Q1
0).

The client 12 of the distribution destination at P4 in FIG.
The management server 13 that has received the normal writing end notification or the abnormal writing end notification from the distribution client 1
The post-distribution processing execution command is transmitted to 2.

In Q11 of FIG. 3, the distribution destination client 12, which has received the post-distribution processing execution command from the management server 13, executes pre-distribution processing according to the post-distribution processing program 30 of the program memory 25 in Q12. . Specifically, the business process using the program stored in the program area 28 is started. Then, the execution result of the post-distribution processing is transmitted to the management server 13 (Q1
3).

The client 12 of the distribution destination at P6 in FIG.
The management server 13, which has received the execution result of the post-distribution process normal end from the M / M device 16 in P8, confirms in P7 that the previous write end notification is the normal write end notification.
A program distribution normal end message is displayed in and the program distribution process this time ends.

It should be noted that the client 12 of the distribution destination attempts to write a program in the program area 28 of the distributed program in Q7 of FIG. 3 or to write a program exceeding the storage capacity of the program area 28. If so, in Q9, if the current version is equal to or less than the previous version, it is determined that the current distribution program 20 has not been normally written.

In this case, the process proceeds to Q14, and the program before update saved in the buffer area 29 is written in the program area 28. Then, the abnormal writing end notification is transmitted to the management server 13 (Q15).

The client 12 of the distribution destination at P4 in FIG.
The management server 13 that has received the abnormal writing end notification from
In P5, the post-distribution processing execution command is transmitted to the distribution destination client 12. That is, regardless of whether the distribution program 20 is normally written in the program area 28 in the distribution destination client 12, the management server 13
In P5, a post-distribution processing execution command is sent.

In this case, the abnormal write end notification is detected at P7 in FIG.
Is not normally written in the program area 28,
An abnormal end message indicating that the program before update is running is displayed on the M / M device 16.

If the pre-distribution process of Q2 and Q3 in FIG. 3 is not normally completed, and if the post-distribution process is not normally completed in Q12 of FIG. 3, the execution result of the abnormal end is It is transmitted to the management server 13.

In this case, the management server 13 uses P in FIG.
In 2 or P6, the abnormal end is detected, the process proceeds to P9, the abnormal place is displayed and output to the M / M device 16, and the program distribution process is ended.

In the data distribution device of the computer system configured as described above, for example, the operator operates the management server 1
When a program distribution command designating the distribution destination client 12 and the distribution program 20 is input from the M / M device 16 of No. 3, before the distribution program 20 is distributed to the distribution destination client 12 via the transmission line 11, In the client 12 of the distribution destination, the work being executed is ended according to the program stored in the program area 28.

After that, the distribution program 20 is distributed from the management server 13, and the distribution destination client 1
The program in the second program area 28 is updated to the distribution program 20. Further, after the updating process of this program is completed, the post-distribution process necessary for resuming the work is automatically executed.

Therefore, unlike the conventional method, the operator does not need to perform the pre-distribution processing and the post-distribution processing by the manual operation from the management server 13, so that the program distribution work efficiency is improved.

Further, when the pre-distribution process is started, the pre-update program stored in the program area 28 is saved in the buffer area 29 after the work using the pre-update program is forcibly terminated. If the distributed program 20 does not normally update the program in the program area 28, the program before update saved in the buffer area 29 is the program area 28.
Is written to.

Therefore, even if an abnormality occurs in the process of updating the program, it is possible to resume the work with the program before the update for the time being, and it is possible to minimize the trouble range of the work.

FIG. 4 is a schematic block diagram of a client / server system in which a data distribution device according to another embodiment of the present invention is incorporated. One management server 13a and a plurality of clients 12a are connected to the transmission line 11.

A database 41 and a buffer area 42 are formed in each client 12a. Then, each client 12a executes a task of searching the data stored in the database 41 as needed.

Generally, in the database 41, in order to always cover the latest data, the data stored in the database 41 is frequently updated. Then, the data in the database 41 of each client 12a is updated by the management server 13a.

FIG. 5 is a flow chart showing a data distribution process for data stored in the database 41 from the management server 13a to each client 12a. When the operator inputs a data distribution command to the management server 13a, the management server 13a sends each client 12a.
A pre-distribution processing command is sent to. Then, in R1, each client 12a executes the data search prohibition process. When the data search prohibited state is entered, the update target data is saved in the buffer area 42.

When the above pre-distribution processing is completed, the distribution data is transmitted from the management server 13a to each client 12a and written in the database 41 (R3).
When the data is normally written in the database 41 (R
4), the data search prohibition is lifted, and the database 41
The data retrieval business for can be executed (R5). Then, the management server 13a, which has received the data write success notification from the client 12a, outputs and outputs the data distribution normal end.

When the data is not normally written in the database 41 in R4, the original data saved in the buffer area 42 is written in the original position of the database 41 in R6 ( R6). Then, the data write failure is notified to the management server 13a (R7). Release the data search prohibition after the data write failure notification (R
8). The management server 13a which has received the data write failure notification from the client 12a displays and outputs the data distribution abnormality.

Even in the data distribution apparatus configured as described above, when updating the data stored in the database 41 of each client 12a, the pre-distribution processing and the post-distribution processing are automatically executed. The same effects as those of the embodiment can be obtained.

The present invention is not limited to the above embodiments. In each embodiment, the case where the program data or searched data already stored in the program area 28 or the database 41 is updated to new data has been shown. However, it goes without saying that it is also applied when newly writing data. Further, the computer system is not limited to the client / server system of the embodiment, but can be applied to various systems.
