2. Description of the Related Art In recent years, in information systems such as AV servers and databases that handle video and audio information, the amount of information managed is enormous, sometimes reaching several hundred Terabytes. Also, the file size handled is large, sometimes reaching several gigabytes to several tens gigabytes.

[0003] In such an information system, management of the capacity of the file system is particularly important. That is, when the capacity of the file system reaches the maximum value, a serious trouble such as system stoppage occurs, so that it is necessary to manage the capacity. For example, the system is monitored with a predetermined capacity such as 90% of the maximum value as an upper limit, and when the capacity of the file system reaches this upper limit, a file is selected based on a preset priority and moved to a library. Make space and make a backup.

[0004] Software for managing such a file system is called migration software. As with other software, for example, the migration software is used after the use contract is signed between the provider and the user, and the source code is modularized according to the system. The migration software has advantages / disadvantages depending on the capacity of the file system to be applied, and is effective when applied to a system with a larger capacity.

[0005]

Heretofore, there has been a problem that an algorithm for license management has not been incorporated in this migration software. Therefore, there is a problem that a module may be illegally copied and used between hosts.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of the configuration of an information system 100 to which the present invention can be applied. For the network 1, a server computer (hereinafter abbreviated as a server) 2 and a plurality of client computers (hereinafter abbreviated as a client) 4,
,... Are connected. The database 3 is hosted on the server 2. Also, file systems 5, 5,
Are constructed on a hard disk or the like, have a very large capacity of, for example, several hundred Tbytes, and use the corresponding clients 4, 4,.

The server 2 and the clients 4, 4,...
Operates, for example, UNIX as an OS (Operation System). In UNIX, a connected storage device such as a hard disk is allocated to a file system by a work called mounting. By being mounted, the storage device and the like are made usable in the system. Also, many of the basic functions of UNIX are performed by processes called daemons that appear to automatically start themselves. Further, the program is managed and executed in units called modules.

A library device 7 is connected to the server 2 via a personal computer 6. The library device 7 has, for example, several hundred data cassettes stored in a cassette shelf 11 and has a plurality of drives 10A, 10B, 10C, and 10D for reading / writing data from / to the data cassettes. For example, several Gbytes of data can be recorded on one data cassette.

The library device 7 has a robot mechanism (not shown), and can automatically select a predetermined data cassette and read / write data under the control of the personal computer 6 based on instructions from the server 2. it can. The data cassette can be replenished or taken out from the input slot 8 and the output slot 9. Although not shown, the library device 7 has a personal computer that manages itself.

In the information system 100, migration software is installed to manage the file systems 5, 5,..., The database 3, and the library device 7. In the information system 100, protection and maintenance of the file systems 5, 5,... And the database 3 are performed by the installed migration software.

The migration software is provided by being recorded on a recording medium such as a CD-ROM or a magnetic tape. The recording medium is recorded, for example, in the form of a source code, and is appropriately constructed as an executable module when mounted on a system. The migration software is composed of a plurality of modules. In this example, migration software is composed of a library control module 12, a database management module 13 mounted on the server 2, and a file system monitoring module 14 mounted on the client 4.

Hereinafter, an operation of the information system 100 using the migration software will be schematically described. For example, when the information system 100 is started, in the server 2, the library control module 12 and the database management module 13 are started. that time,
The license of the migration software is confirmed based on predetermined conditions by a method described later.

Subsequently, in each of the clients 4, 4,..., The file system monitoring module 14
Is started and the migration file system is mounted. The migration file system is a file system using migration software. At the time of mounting, similarly to the above, the license of the migration software is confirmed based on predetermined conditions by the method described later. Hereinafter, one of the plurality of connected clients 4, 4,... Will be described.

When the migration file system is mounted on the client 4, the data in the file system 5 is moved to the migration file system. As a result, the data is placed under the monitoring of the migration monitoring module 14. The migration monitoring module 14 starts a migration file system monitoring daemon. When the migration file system monitoring daemon detects that the data of the file system has reached a certain capacity, the migration command for performing the data migration processing is issued to the modules 12 and 13 in the server 2. . For example, data to be moved from the file system 5 is selected based on a preset priority or the like.

In the server 2, data to be moved is registered in the database 3 by the database management module 13. Then, an instruction is issued from the database management module 13 to the library control module 12, and a predetermined tape mount is performed. In the module 12, the library device 7 is
Control. With this control, in the library device 7,
For example, a predetermined tape is taken out from the tape shelf 11 and set in an appropriate one of the drives 10A to 10D.
The tape is ready for writing data.

In the server 2, data is written to the tape by a tape I / O module that controls writing and reading of data to and from the tape in the library device 7. When the data writing is completed, a completion notification is sent from the modules 12 and 13 of the server 2 to the file system monitoring module 14. In response to this notification, the file system monitoring module 14 deletes the corresponding data on the file system 5, moves the data, and completes the migration process.

The configuration shown in FIG. 1 and the processing in the configuration are merely examples, and the present invention is not limited to this.

Next, a method of confirming the license of the migration software described above will be described. First, the migration software is transferred to the information system 10.
At the time of introduction, a predetermined contract is concluded between the software provider and the user, and a license is given to the user. The license is provided according to the size of the information system 100 to be contracted.

For example, at the time of contract, the information system 100
The capacity of the entire file system is calculated, and a contract is made with a capacity having a certain margin for the capacity as a license capacity. The database 3 and the library device 7 are contracted for the number of files and the number of devices, and the number of modules that can be started is determined based on the contract. The set license capacity and the number of module licenses are key-coded and stored in the system.

On the other hand, each of the hosts (the server 2, the clients 4, 4,..., Etc.) constituting the information system 100 is given a unique ID in advance. Then, at the time of contract, each ID of the host using the migration software is key-coded and held in the system.

Each time the migration software is started, it is checked whether the user is observing the license provided at the time of contract. As described above, the migration software is composed of multiple modules with different purposes and processes.
The check is performed for each of these modules.

FIG. 2 is a flowchart showing an example of the license management process in the file system monitoring module 14. This process is performed for each corresponding host. In the example shown in FIG. 1, the clients 4, 4,.
This process is performed in each of the steps of

At the first step S10, the file system 5 is mounted and the file system monitoring module 14 is started. Then, in the next step S11, the capacity of the mounted file system 5 is calculated. At this time, not only the currently mounted file system but also the past mounted ones are referred to, and the capacity is calculated including these.

When the capacity is obtained, in step S12,
The calculated capacity is compared with the license capacity. At the same time, the ID of the host on which the module was started
Is compared with the ID set in the license.

In the next step S13, step S12
It is determined whether or not the result of the comparison at step satisfies a predetermined condition. That is, when the calculated capacity is equal to or smaller than the license capacity, and the host ID matches the ID in the license, it is determined that the condition is satisfied.
If the condition is satisfied, the process proceeds to step S14, and a mount success process is performed. That is, the migration file system is mounted by the file system monitoring module 14. Then, this is displayed in step S15.

On the other hand, if it is determined in step S13 that the above condition is not satisfied, the process proceeds to step S16. If the conditions are not satisfied, the file system monitoring module 14 cannot be used, so it is determined that the mounting of the migration file system has failed, error processing is performed, and the fact is displayed in step S15.

FIG. 3 shows a flowchart of an example of license management processing in the library control module 12 and the database management module 13. In these cases, the right to execute the module is given only to the number permitted to be activated at the time of licensing. For example, in the database 3, the execution right of one database management module 13 is given to one database 3. The same applies to the library control module 12.

Here, the database management module 13 for managing the database 3 will be described as an example. This process is also performed for each corresponding host, as described above. In the example shown in FIG. 1, the database 3 is executed on the server 2 because it exists only on the server 2.

In the first step S20, the type and number of activated modules are checked. In the type, for example, a plurality of modules are started and operated simultaneously in the server 2. Among them, in this example, whether or not the module targeted by the database management module 13 is started, and whether or not the module is started If so, the number is checked. This is performed, for example, by counting the number of target daemons developed on the memory of the server 2.

In the next step S21, step S20
It is determined whether the result of the check in satisfies a predetermined condition. That is, it is determined whether the activation number of the predetermined module is equal to or less than the number contracted at the time of license. If the condition is satisfied, the process proceeds to a normal start routine in step S22, and the database management module 13 is started.

On the other hand, if it is determined in step S21 that the above-mentioned condition is not satisfied, the modules as many as the number permitted by the license are activated. Then, the process proceeds to step S23, where an error process is performed, and the fact is displayed in step S24.

The process shown in FIG. 3 is performed in the library control module 12 in the same procedure.
