DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a client license management method and apparatus for managing access from a client application program to a server application program in a client server system, and a recording medium on which a client license management program is recorded.

[0002]

2. Description of the Related Art In recent years, in a client-server system including a server and a plurality of clients connected to the server via a network, a client application program is downloaded from the server to the client, and the downloaded client program is downloaded. Some implement an automatic installation function for installing an application on a client. Such an automatic installation function is realized by an OS (Operating System) existing in the client and the server. Further, the client application program installed in the client accesses the server application program of the server so that the client application program and the server application program exchange information with each other via a network to perform predetermined processing. The operation is performed.

Since the automatic installation function of the client application program to the client is automatically executed by the server and the OS of the client, it is difficult to limit the number of client application programs downloaded from the server to the client. It is. Therefore, the license management of the client application program is performed by limiting the number of accesses to the server application program by the client application.

That is, access to a server application program by a client application is restricted according to the number of licenses preset for the client application program. The number of licenses is indicated by the total number of clients permitted to use the application program. Therefore, in the conventional client license management method, when each client accesses the server application program of the server based on the client application program downloaded to each client,
The license management of the client application program is performed by limiting the number of clients that can access the server so as not to exceed the number of licenses.

[0005]

The above-described conventional client license management method has the following problems. Since the client application program is automatically downloaded to the client by the OS of the client, the server does not know and manage the number of clients to which the application program has been downloaded and installed.
For this reason, the client application program can be downloaded to a client exceeding the number of licenses defined corresponding to the application program.

Therefore, as long as a client exceeding the number of licenses does not access the server at the same time, any client in which the client application program is installed can access the server application program of the server. For this reason, there is a problem that it is not possible to prohibit access to a client exceeding the number of licenses. In addition, the client application program is automatically downloaded to the client by the OS of the client and the server, and the server cannot identify the client from which the application program has been downloaded. is there.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a client and server operating system.
In the client-server system that downloads and installs the client application program from the server to the client with the automatic installation function provided by the server, the license management of the application is performed on a client-by-client basis, and only the authorized client is sent to the server An object of the present invention is to provide a method and an apparatus for managing a client license capable of permitting access, and a recording medium recording a client license management program.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a client license management method according to the present invention will be described, and at the same time, an embodiment of a client license management apparatus and a recording medium storing a client license management program will be described. FIG. 1 is a configuration diagram of a server client system to which the client license management method of the present invention is applied, FIG. 2 is a flowchart for explaining the operation of a server started by a client accessing the server, and FIG. 9 is a flowchart for explaining the operation of the server that is started when the notification is made.

As shown in FIG. 1, a server 10 and a plurality of clients 20 are connected via a network N to form a server client system. The server 10 and each client 20 have an IP address (Intern)
et Protocol Address). This IP address is unique address information given to the server and the client connected to the network N, and is set so as not to be duplicated in the network N. That is, each client 20 can be specified by this IP address. When the client 20 accesses the server 10, the IP address of the client 20 is notified to the server 10. I have.

The server 10 has a client application program module management unit 12, a server application program 14, a license management table 16, a license management unit 18, and a storage device 19.

The client application program module management section 12 is constituted by the OS of the server 10 and manages client application programs to be downloaded to each client 20.

The server application program 14
Is for transmitting and receiving information to and from each other by an access from the client application program 24 of the client 20 to execute a predetermined process.

The license management table 16 is for registering the IP address of the client 20 to which the use permission of the client application program has been given.

The license management unit 18 registers and deletes an IP address in the license management table 16 and registers the IP address registered in the license management table 16.
The number of addresses is counted, and it is determined whether the counted value is less than or equal to a predetermined number of licenses permitted for the client application program. Further, the license management unit 18 determines permission or prohibition of access to the server application program 14 from the client application program 24 and notifies the server application program 14 of the determined content. Storage device 19
Is for reading a program executed by the server (computer) 10 from the recording medium 19A, and is managed by the OS of the server 10. The client license management program of the present invention is also recorded on the recording medium 19A, and the management program read from the recording medium 19A is read from the storage device 19 and installed on the server 10. . The storage device 19 and the recording medium 19A are composed of, for example, a floppy disk drive device and a floppy disk.

The client 20 has an automatic installation control unit 22, a client application program 24, and an uninstall tool 26.

The automatic installation control unit 22 is constituted by an OS of the client 20, downloads the client application program from the client application program module management unit 12 by accessing the server 10, and downloads the downloaded client application program. Install the program.

When the client application program 24 is started and executed, the server application program 14 of the server 10 via the network N
, The information is exchanged with each other, and a predetermined process is executed.

The uninstall tool 26 has a function of deleting the client application program 24 installed in the client 20. In the present invention, the uninstall tool 2
6 notifies the license management unit 18 of the server 10 that the client application program 24 has been deleted.

Next, the operation will be described with reference to FIGS. In FIG. 1, when a request to download a client application program is issued,
The client application program is downloaded from the client application program module management unit 12 of the server 20 via the network N and installed on the client 20 as the client application program 24.

After the client application program 24 is installed on the client 20,
By being activated on the client 20, an attempt is made to access the server application program 14 of the server 10. At the time of this access, the I
The P address is notified to the server 10.

The server application program 14
The license management unit 1 reports that the client application program 24 of the client 20 has accessed, together with the IP address of the client 20.
Notify 8.

The server 10 starts the processing shown in FIG. That is,
The license management unit 18 of the server 10 executes a registration determination step of checking whether the notified IP address of the client 20 is registered in the license management table 16 (S100).

When the notified IP address of the client 20 is registered in the license management table 16 ("Y" in S100), the license management unit 18 accesses the server application program 14 from the client application program 24. Server application program 1
4 is executed (S10).
2). Therefore, after this access is permitted, the server application program 14 and the client application program 24 execute predetermined processing operations while exchanging information via the network N.

On the other hand, the IP address of the notified client 20
If the address is not registered in the license management table 16 (“N” in S100), the license management unit 18
Executes a license number determination step of checking whether the number of IP addresses of the client 20 registered in the license management table 16 at that time is smaller than or equal to a predetermined number of licenses permitted for the client application program. (S104).

If the number of IP addresses registered in the license management table 16 is smaller than the predetermined number of permitted licenses ("Y" in S104), the license management unit 18 sends the license information to the client 2 accessing the server 10.
0 is registered in the license management table 16, and after registering the IP address in the license management table 16, the server application program 24 permits access from the client application program 24 to the server application program 14. Then, a license registration step of notifying 14 is executed (S106). Therefore,
After this access is permitted, the server application program 14 performs a predetermined processing operation while exchanging information with the client application program 24 via the network N.

On the other hand, when the number of IP addresses registered in the license management table 16 is equal to the number of permitted licenses, the license management unit 18 gives the server application program 14 access from the client application program 24 of the client 20. Notify that permission is not granted. Server application program 14 that has been notified that access is not permitted
Executes a license non-registration step of rejecting access to the client application program 24 and notifying the access rejection via the network N (S108). And server 1
0 ends a series of processing. The client application program 24, which has received the notification of denying the access, displays information indicating that the access is denied on a display or the like of the client 20, and thereby the operator of the client 20 is denied access. Notify that. Therefore, the operator of the client 20 can recognize that the access to the server 10 by the client application program 24 has been rejected because the license has not been registered.

Next, referring to FIG. 1 and FIG. 3, an operation for deleting the client application program 26 installed in the client 20 will be described. The deletion of the client application program 26 in the client 20 is performed by the uninstall tool 26. The uninstall tool 26 is a client application program 2
4 from the client 20 and the server 10
And notifies the license management unit 18 that the client application program 24 has been deleted from the client 20.

The license management unit 18 of the server 10 that has received the notification that the client application program 24 has been deleted activates the processing shown in FIG. That is, the IP registered in the license management table 16
A client application uninstallation step of deleting an IP address that matches the notified IP address of the client 20 from among the addresses is executed (S120), and a series of processing ends.

Here, a description will be given of a processing procedure performed when the client 20 using the client application program is changed to another client. That is, the client application program 24 is deleted from the client 20 that no longer uses the client application program 24, and the IP address of the client 20 registered in the license management table 16 is deleted from the license management table 16.

Thereafter, the newly used client 20
, A request to download the client application program is generated, and the automatic installation control unit 22 of the client 20 to be newly used is
Downloads the client application program from the client application program module management unit 12 of the server 20 via the network N and installs the client application program as the client application program 24 on the client 20.

Then, similarly to the case described above, the installed client application program 24 is activated on the client 20 to try to access the server application program 14 of the server 10 and to obtain the license management table 16. If the number of IP addresses registered in the server 10 is smaller than the number of licenses, the IP address of the client 20 is registered in the license management table 16, and the client 20 uses the client application program 24 to execute the server application of the server 10. 14 is permitted. That is, the client application program 24
Can be used.

In the above embodiment, the client 2
0 of the server application program 14 of the server 10
The IP addresses of the accessing clients 20 are registered in the license management table 16 in the order of access. Therefore, even if the client application program 24 is installed in a client whose number is larger than the number of licenses permitted in advance, the client application program 24 for which the IP address of the client is not registered in the license management table 16 is sent to the server. Access to the application program for access 14 is denied.
That is, application license management can be performed on a client-by-client basis, and only a client having a client application to which access is permitted is permitted to connect to the server and access the server application program. Therefore, unlike the related art, it is possible to prohibit a client exceeding the license number from accessing the server.

In the above-described embodiment, when the number of IP addresses registered in the license management table 16 is smaller than the predetermined number of permitted licenses, the license management unit 18 determines whether the client accessing the server 10 License management table 1 for 20 IP addresses
After registering the IP address in the license management table 16, the server application program 14 is notified that access to the server application program 14 from the client application program 24 is permitted. However, the process may be terminated once when the IP address is registered in the license management table 16, and the connection between the server 10 and the client 20 may be disconnected.
In this case, when the client application program 24 in which the IP address is registered attempts to access the server application program 14 of the server 10, access to the server application program 14 is permitted according to the above-described procedure. The server application program 14 performs a predetermined processing operation while exchanging information with the client application program 24 via the network N.

In the above-described embodiment, the IP address is registered in the license management table using client identification information for identifying each client. However, as the client identification information for identifying each client, Machine ID (I) assigned to each client connected to the network so as not to be duplicated
Needless to say, it is also possible to use (Denification) or a client name.

In the above-described embodiment, the server 10 executing the registration determining step, the access permitting step, the license number determining step, the license registering step, the license non-registering step, and the client application uninstalling step, respectively, A license number determining unit, a license registering unit, a license non-registering unit, and a client application uninstalling unit are realized. Also, a client license management program executed by the server 10, that is, a registration determination step,
A management program including an access permission step, a license number determination step, a license registration step, a license non-registration step, and a client application uninstallation step is recorded on the recording medium 19A. Then, the management program recorded on the recording medium 19A is read out by the storage device 19 and
It is configured to be installed and executable. The recording medium for recording the client license management program is not limited to a floppy disk, but may be, for example, an optical disk, a magneto-optical disk, a ROM, a RAM, or the like.
