Description

[Detailed Description of the Invention] [Outline] The registration information of the selected product is stored in a logical volume management file that stores the management information of each logical volume. By extracting the logical volume name in which the selected product is stored and providing the processing means for performing the starting process, the selected product can be registered in any logical volume. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing system including a large-capacity external storage device and a plurality of selected products, and more particularly to a selected product management processing system capable of registering a selected product in an arbitrary logical volume. It is a thing. Recently, with the increase in capacity of external storage devices such as hard disk devices, the external storage devices have been divided and used as so-called logical volumes according to their applications. The introduction of logical volumes enables flexible management of storage areas, and when a hard error occurs, it is possible to reduce the impact on other logical volumes only by repairing the failed logical volume. become. When a selected product such as a paid program is registered in this logical volume, it is desired that the user can store it in the logical volume desired by the user. [Prior Art] Usually, in a commonly used operating system, files can be hierarchically managed by directories. And, for example,
By associating this directory with a logical volume, the external storage device is divided into a plurality of logical volumes for management. By the way, conventionally, when a selected product consisting of a specific program such as a paid program is registered in the system, it can be stored only in a specific volume. The reason is that the program that activates the selected product has the storage volume name of the selected product fixed in the program. For example, a Japanese language processing program and a spreadsheet program may be provided as separate selection products, and the spreadsheet program may be called from the Japanese language processing program. When linking between selected programs in this way, the selected product on the calling side stores the storage volume name fixedly so that the user does not become aware of the storage volume name of the linked selected product. It is supposed to do. [Problems to be Solved by the Invention] According to the above conventional method, the selected product can be stored only in a specific volume. Therefore, when the user newly purchases the selected product, the selected product is stored in the specific volume. If there is no free space, the selected product cannot be registered. Therefore, there is a problem that it may not be possible to use the new selected product. Also, when changing the storage location of the selected product,
There was a problem in that the program that started it or other related program itself had to be modified. The present invention solves the above problems, stores a selected product in an arbitrary logical volume selected by a user, makes it available, and even if the storage destination of the selected product is changed, other It is an object of the present invention to provide a means for eliminating the need to modify the system program and the user program of. [Means for Solving the Problems] FIG. 1 shows a basic configuration example of the present invention. In FIG. 1, 10 is a display, 11 is a processing unit consisting of a CPU and memory, 12 is a logical volume operation processing unit that creates and deletes logical volumes, and 13 is a selected product that registers and deletes selected products. An operation processing unit, 14 is a selected product activation processing unit that activates a selected product, 15 is a path name table creation unit that creates a path name table, 16 is a path name table that stores information about the storage volume of the selected product, and 17 is a fee Selected products such as programs, 18 is a logical volume management processor that manages logical volumes, 19-1 and 19-2 are hardware
An external storage device such as a disk device, 20 is a logical volume management file, 21-1 to 21-3 are selected product storage files, 22-1 to 22-3 are other files, D1
~ D3 is the display screen of the display, and LV11 to LV23 are logical volumes. Logical volume management file to enable users to store selected products in any logical volume
20 is provided, and the logical volume management file 20 stores management information including usage information of logical volumes and registration / non-registration information of selected products. When registering the selected product in the system, the selected product operation processing unit 13 secures a selected product storage file on the specified logical volume, and reads and stores the selected product from a provision medium such as a floppy disk. It is a thing. At this time, the fact that the selected product has been registered is entered in the relevant logical volume management information in the logical volume management file 20. The selected product activation processing unit 14 performs the activation processing of the specified selected product 17, and according to the logical volume name of the selected product storage file read from the logical volume management file 20, the selected product 17
Is loaded on the memory and the startup process is performed. In addition, the path name table creation unit 15
The path name table 16 is created for the cooperation processing of 17.
The path name table 16 is a list of directories related to selected product storage files. The logical volume operation processing unit 12 performs processing such as creation of a logical volume, and the logical volume management processing unit 18
Write processing and read processing for the logical volume management file 20 are performed. [Operation] The logical volume operation processing unit 12 displays the logical volume operation screen D1 on the display 10 and creates a specified logical volume by dialogue with the user. At this time, the usage of the logical volume, the size, whether or not the selected product can be registered, and the ratio of discrete files to continuous files can be specified. These pieces of designation information are written in the logical volume management file 20 via the logical volume management processing unit 18. Also, it deletes unnecessary logical volumes as specified. The selected product operation processing unit 13 displays on the display 10.
The registration / deletion operation screen D2 of the selected product is displayed, and the selected product is registered in the logical volume or deleted while interacting with the user. The registration presence / absence information of the selected product is reflected in the logical volume management file 20 via the logical volume management processing unit 18. The selected product activation processing unit 14 displays an instruction screen D3 for processing by the selected product on the display 10 and performs processing for activating the designated selected product. If the directory is not explicitly specified, the logical volume that stores the selected product is the logical volume management processing unit.
The logical volume management file 20 read via 18 is searched. Therefore, no matter which logical volume the selected product is stored in, the selected product can be activated. [Embodiment] FIG. 2 is an explanatory diagram of logical volume management information according to an embodiment of the present invention, FIG. 3 is an explanatory diagram of a path name table, FIG. 4 is an explanatory diagram of directories related to a logical volume, and FIG. FIG. 6 is an explanatory diagram of a selected product operation process according to an embodiment of the present invention, and FIG. 6 is an explanatory diagram of a selected product activation process according to an embodiment of the present invention. The logical volume management information registered in the logical volume management file 20 is, for example, information as shown in FIG. As the logical volume management information, for each logical volume, the logical volume name, its usage information, selected product registration / non-registration information, logical volume installation destination information, information on whether or not to automatically install the logical volume, location information, Size information, discrete file / continuous file ratio information, etc. are stored. The usage information of a logical volume is information such as whether the logical volume can store work files, user files, spool files, and memory dump information output files. . If the file is for storing user files, it also includes information on whether the selected product can be registered. When the selected product operation processing unit 13 performs the selected product registration process, whether or not the selected product can be registered is determined by referring to the logical volume management file 20, and if the selected product is registered, the selected product is registered. Information is set. The path name table creation unit 15 in the selected product activation processing unit 14 creates a path name table 16 as shown in FIG. 3, for example, based on the registration presence / absence information of the selected product. This path name table 16 contains the directory name (LV1
1, LV21, LV22, ...) And the directory name for the selected product (for example, “lpp”) is stored. In the selected product linkage process, only the selected product name is specified, so the path name table
16 creates a path and sequentially searches the storage logical volume. The logical volume is managed by a directory as shown in FIG. 4, for example. In FIG. 4, circles are directories and squares are files. The highest-level directory is the root directory 30, and the volume in which this root directory 30 exists constitutes the root file system 31. The other file system 32 is linked to the directory of the root file system 31 by a so-called mount process. As a result, the root directory 30
It can be traced from. The logical volume is associated with this one directory, and the logical volume name and the directory name match. Previously, the selected product had to exist in the root file system 31, but
Based on the logical volume management file 20, the search for the logical volume in which the selected product is stored, that is, the automatic search by the directory corresponding to the logical volume is performed, so even if there is a selected product other than the root file system 31, You can launch it. The registration processing of the selected product by the selected product operation processing unit 13 shown in FIG. 1 is as shown in FIG. 5, for example. In the following description, 〜 corresponds to the process 示 す shown in FIG. Enter the name of the logical volume that stores the selected product through the interactive process with the user. Read the logical volume management file 20 and search for the relevant logical volume management information by the specified logical volume name. Selection of logical volume management information It is determined whether the product registration availability information indicates that registration is possible. If registration is not possible, control is transferred to processing. If the selected product can be registered, the selected product is registered in the specified logical volume. In the logical volume management file 20, enter the selected product registration information field of the relevant logical volume management information
Register selected products. After that, the process ends normally. If the selected product cannot be registered, an error message is displayed and the process ends. Or, return control to the process and reenter the correct logical volume name. When there is a request to activate a selected product, the selected product activation processing unit 14 shown in FIG. 1 executes the processing shown in FIG. 6, for example. In the following description, ~ corresponds to the processing ~ shown in Fig. 6. Determine whether the selected product is activated. If the selected product is not activated, the same activation process as in the past is performed. If the selected product is activated, it is determined whether or not there is a path name table. If the path name table has already been created, control is transferred to the processing. If there is no path name table, read the logical volume management file 20. Extract the logical volume in which the selected product is registered from the logical volume management information and create a path name table. It is determined whether the directory of the selected product is specified at the time of the start request. If specified, transfers control to the process. Extract one logical volume directory name from the path name table. Specify the directory name of the logical volume and load the selected product. Determine if the selected product has been loaded successfully. If it fails, control is passed to the process. If the loading of the selected product is successful, control is passed to the selected product and the startup process ends. If the load fails, determine whether the search of the path name table has finished. If not completed, control is returned to the process, the next directory name is fetched from the path name table, and the same process is repeated. If all path name table searches are completed, the startup has failed.
Terminated abnormally. If a directory is specified, the selected product will be loaded according to that directory. Pass control to the selected product and start it. Since the selected product is activated by the above processing, it can be activated regardless of the logical volume of the selected product. [Effects of the Invention] As described above, according to the present invention, the selected product can be stored in a plurality of arbitrary logical volumes designated by the user. Even if the storage location of the selected product changes, the system program and user program do not need to be modified. In particular, when linking between selected products such as calling a spreadsheet program from a Japanese processing program, the calling Japanese processing program can be called without being aware of the storage location of the spreadsheet program. Therefore, the flexibility regarding the operation of the selected product is improved. Further, when the selected product is started, only the logical volume in which the selected product is stored is searched, so the startup processing is faster than when searching all logical volumes.
