[Industrial application field]

The present invention relates to a data processing system equipped with a large-capacity external storage device and a plurality of selected products, and more particularly to a selected product management processing method that allows selected products to be registered in any logical volume.

Recently, with the increase in the capacity of external storage devices such as hard disk drives, external storage devices are being divided and used as so-called logical volumes according to their purpose. The introduction of logical volumes has made it possible to manage storage areas flexibly. Furthermore, when a hard error occurs, it is possible to reduce the impact on other logical volumes by simply repairing the failed logical volume. When registering a selected product such as a paid program to this logical volume, it is desired that the user be able to store it in the logical volume of his or her choice, and also be able to quickly retrieve and start processing when necessary.

[Problems to be solved by conventional technology and inventions] Usually,
Commonly used operating systems allow files to be managed hierarchically using directories. For example, by associating this directory with a logical volume, an external storage device is managed by dividing it into a plurality of logical volumes. Furthermore, when a selected product consisting of a specific program such as a paid program is registered in the system, it can be stored in any logical volume.

By the way, when managing an external storage device by dividing it into a plurality of logical volumes, a method can be considered in which a logical volume management file is provided and the registered selected product name is stored in this file. However, in this case, although it is found by searching the logical volume management file that the selected product is registered in one of the logical volumes, it is unclear in which logical volume it is registered.

For this reason, especially if the selected product is registered in multiple logical volumes, when starting the selected product, it is necessary to sequentially search and find the target logical volumes, and in the worst case, all logical volumes Therefore, there was a problem in that it was not possible to quickly find the desired selected product and perform the activation process.

The present invention provides a selected product management file that stores the storage location of the selected product, and at the time of startup, refers to this selected product management file to find the storage location of the selected product and quickly performs the startup process. There is.

[Means for solving problems]

The selected product operation processing unit 13 stores the designated selected product in a logical volume, and also stores the stored selected product name and storage location in the selected product management file 20.

The selected product activation processing unit 14 finds the storage location of the specified selected product from the selected product management file 20, and stores the found storage location (selected product storage file PPI in logical volume LVII, etc.).
This process starts the selected product retrieved from the .

[Effect]

As shown in FIG. 1, in the present invention, the selected product operation processing unit 13 refers to the information on whether or not the selected product can be registered to the logical volume in the logical volume management file 19, and selects a logical volume that can be registered. The selected product is stored, and the stored selected product name and storage location are stored in the selected product management file 20. At startup, the selected product startup processing unit 14 stores the selected product specified in the selected product management file 20. The storage location corresponding to the product name is found, the selected product is read from the found storage location and loaded onto the memory, and the startup process is performed.

Therefore, when starting a selected product, the storage location of the selected product is found in the selected product management file 20, and the selected product is retrieved from the found storage location and loaded into memory for startup processing, resulting in faster startup. It becomes possible to perform processing.
