Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program installation device, and more particularly to a program installation device for installing (installing or installing) a program on a disk medium.

[0002]

2. Description of the Related Art First, a storage device using a general disk medium will be described. As shown in FIG. 6, the disk 56 has a circumferential data storage groove called a track from the center thereof, and a large number of the data storage grooves are arranged from the outer peripheral portion toward the inner side. Further, FIG. 7 is a schematic representation of this track in a linear form. Each track is divided into a plurality of records having a fixed storage capacity area starting from the starting point marker section 57.

For a storage device using such a disk medium, a track number, a record number, and an operation are designated by a computer located at a higher level, so that the access arm 52 is moved to a corresponding track position. A read operation for reading data and a write operation for writing data are performed from the time when the record to be rotated reaches the head portion 53 at the tip of the arm.

Further, in the record which is the minimum storage area, since the storage capacity is constant, in order to virtually store a file having a size exceeding that size in this disk storage medium, a plurality of files are stored. Although it becomes necessary to use records, generally, the arrangement of each record is arbitrarily determined if it is a blank record.

Due to such a structure, if data is sequentially stored in consecutive records and tracks in one file, the access speed will be greatly affected when accessing the logically connected records. Possible head movement time can be minimized, resulting in faster program execution speed.

Further, in Japanese Patent Laid-Open No. 3-113527, as an extension of this speed improving means, by monitoring the correlation in which order access is made between a plurality of files, There is disclosed a method of dynamically rearranging files, which are expected to be deeply correlated with each other in access order, on the basis of the statistical result so as to be dynamically adjacent to records and tracks on the disk.

According to this, when the file is accessed next time, it can be expected that the time for the head of the disk to move between the two files can be shortened, and as a result, the access speed between the files can be increased.

[0008]

In the conventional program installation device, data is randomly stored in empty records on the disk, so a file that does not fit in one record is divided into a plurality of records and fragmented on the disk. Be converted. As a result, when the program is executed, the movement amount of the head becomes relatively large, which causes the execution speed to decrease.

Further, in the technique described in Japanese Patent Laid-Open No. 3-113527, the correlation is merely estimated based on the past statistics of the access status to the disk. It is not known whether the files that have a strong correlation are deeply related to each other.Therefore, the method that dynamically rearranges the files that have a strong correlation cannot reliably increase the effective speed. It was

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a program installation device capable of improving the disadvantages of the conventional example and, in particular, capable of surely increasing the effective speed of the installed program.

[0011]

Therefore, in the present invention, as a first means, an installation control means for installing program data in a computer in accordance with an external command, and a capacity after the installation of the program data are file capacity information. And a program capacity storage unit stored as. In addition, the installation control means checks the disk-shaped storage medium of the computer whether there is a continuous free space equal to or larger than the capacity according to the file capacity information, and the disk-shaped storage medium is continuously connected by the capacity inspection section. When it is determined that there is no free space, a data storage unit for moving the data stored in the desk-shaped storage medium to secure the continuous free space is provided.
The configuration is adopted.

In the first means, since the program is installed after the continuous capacity is secured by the capacity securing unit, when the program is executed, the necessary file is read with a small head movement amount. .

In the second means (claim 2), in addition to the item for specifying the first means, a file in which file order information predetermined according to the correlation of the program data is stored in the program capacity storage section. A configuration is adopted in which an order storage unit is provided side by side, and the installation control unit includes an order-based installation unit that installs the program data in an order based on the file order information stored in the file order storage unit.

In the second means, the developer who develops the program specifies the correlation of the files constituting the program as the order of the files. The files having a high correlation are arranged in the close order, and this file order information is stored in the file order storage unit. Then, the order-based installation unit installs the program data in continuous free areas according to the file order information. Therefore, when a file is referenced during the execution of the program, the correlated files are continuously stored, so that the effective speed is improved.

In the third means (claim 3), in addition to the matter for specifying the second means, the file order storage section stores file order information for each combination of program data to be installed, and the program capacity storage section The file capacity information is stored for each combination of the program data to be installed. Further, the installation control means selects a file order information selection unit that selects one of the plurality of file order information based on the externally input installation instruction, and a plurality of file capacity information based on the installation instruction. The configuration is such that a file capacity information selection unit for selecting one is provided.

The present invention aims to achieve the above-mentioned objects by these.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION The program installation device of the present invention has a function of pre-calculating the disk capacity required for the installation prior to the installation and generating / securing a continuous unused area of the disk corresponding to the capacity. Have. In general, when using an application program, it is easy to expect that access to the files related to that application will be concentrated, and this fact makes it possible to install a series of programs in consecutive unused areas. By this, there is a high possibility that the movement amount of the access arm of the disk will be within the continuous area where the installation is performed, and as a result, the execution speed of the application is improved.

Further, it has a storage order information of the storage disk medium for files to be stored in the disk at the time of installation, and accordingly has a function of storing the files in the installed disk storage medium in order. This is because if you are an application developer, you can accurately understand the interrelationships in the files you use (for example, you must always call another specific data file from one execution program file), so these correlated files are adjacent to each other. Then, if it is placed on the disk, the file access speed can be increased more reliably.

As a supplementary note, since most application programs are mostly read-only files when viewed from the host computer, a program once installed by this method may intentionally change the file storage location on the disk. Unless high, a permanent high operating speed is maintained.

Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a program installation device according to the present invention.

As shown in FIG. 1, the program installation device includes installation control means 1 for installing program data in a computer in accordance with an external command,
The storage means 2 stores the program data.

The installation control means 1 includes a capacity inspection unit 12 for inspecting whether or not the disk-shaped storage medium (disk medium) 56 of the computer has a continuous free space equal to or larger than the capacity according to the file capacity information, and this capacity inspection unit. When it is determined by 12 that there is no continuous free space in the disk medium 56, the capacity securing unit 14 that moves the data stored in the desk medium 56 to secure the continuous free space is provided.

The storage means 2 comprises a program capacity storage section 22 that stores the installed capacity of the program data as file capacity information, and a program data storage section 24 that stores the program data to be installed.

In the present embodiment, as the installation form, the form of the installation source medium is not particularly selected, but the installed medium is the disk-shaped medium having the track and record structures as shown in FIGS. 6 and 7. I am assuming.

Further, in this embodiment, the storage means 2 is provided with a file order storage unit 26 which stores file order information which is predetermined according to the correlation of the program data. In response to this, the installation control unit 1 includes the order-based installation unit 16 that installs the program data in the order based on the file order information stored in the file order storage unit 26.

The installation device may install only the program data designated by the user among the plurality of program data. In this example, the file order storage unit stores the file order information for each combination of the program data to be installed, and the program capacity storage unit stores the file capacity information for each combination of the program data to be installed.

Further, the installation control means 1 has a file order information selection unit for selecting one of a plurality of file order information based on an externally input installation command, and a plurality of file capacities based on the installation command. And a file capacity information selection unit for selecting one of the information.

FIG. 3 is a flow chart showing an example of execution of the configuration shown in FIG. In the initial state of the processing, since the installed storage medium has not been subjected to any particular treatment, fragmentation may occur, and the record areas in use of the disk may be scattered everywhere.

When starting the installation of the program, if the file size to be stored in the disk medium to be installed is indefinite due to the desired installation condition, the installation condition is input by the user who performs the installation (step S12). The file capacity information selection unit selects or calculates the required disk capacity according to this installation condition (step S13). Further, thereafter, the disk storage order in which the access speed of the disk to be installed is considered to be higher for the files necessary for the installation selected in the file order information selection unit preceding step is determined (step S14).

Next, the capacity inspecting unit 12 inspects whether or not the required disk capacity is present as a continuous area on the disk to be installed, and if there is no necessary area,
The necessary continuous area is secured by moving the record (step S15).

Next, according to the file storage order obtained in step S14, the program data is stored so as to be successively continuous in the area on the installed disk secured in step S15 (step S16).

If it is possible to add an attribute that makes it impossible to erase the record information to each file in the file system that is being used last, the optimally arranged record position is held by giving that attribute. Therefore, the effect of high-speed program execution can be maintained.

Installation control means 1 according to this embodiment
The operation of can be realized by a computer and a program for instructing the operation of the computer. Therefore, the present invention can be implemented by storing the program for operating the computer as the installation control means in the storage means 2 and supplying the program. The program for executing the installation control means is specified by the capacity detection command, the capacity securing command, and the order-based installation command.

[0034]

Embodiments of the present invention will be described in detail with reference to FIGS.

CD-ROM as an installation source medium
, Which contains three application program file groups, a required disk capacity data file, and an installation order data file. That is, a CD-ROM is adopted as the storage unit 2, and the program data storage unit 24 stores three application program data.

The application file group is the actual state of files of programs and data transferred to the disk medium to be installed at the time of actual installation. Program capacity information (required disk capacity data file)
Is shown in FIG. This file contains all possible installation conditions in the left part of the file, and the corresponding disk space data in bytes on the right. The required disk capacity data file is stored in the program capacity storage unit 22.

The file order information (installation order data file) is shown in FIG. This file exists only for the types of installation conditions, and the file names are listed for each file in the order in which they are stored in the disk to be installed from the beginning of the file. Also, this order is created in advance by the developer of the application software to be installed, considering that the ones having a large correlation are adjacent to each other based on the reference relationship of the files. This installation order data file is app1. ord,
app1. It is stored in the file order storage unit 26 with a file name such as ord.

A magnetic fixed disk (hard disk) is used as the installed medium. This magnetic fixed disk has specifications that specify the storage location of data by tracks and records, and also manages the specification status of each record, the file name / attribute, and the series of record addresses being referenced. VTOC (Vol
It has a disk management area called ume Table of Contents).

In the VTOC file attribute assigning function, a read-only attribute can be added to each file, and a file to which this attribute has been added cannot be erased carelessly. The upper record position is not changed.

Next, the operation of this embodiment will be described.
Description will be given along the operation flow of FIG. In the present embodiment, the CD is used as "Confirm installation condition (S12)".
-Three applications app_ stored in ROM
The user is asked which application to install for 1, app_2 and app_3, and the condition is determined by the answer.

Calculation of Required Disk Capacity (Step S1
3) ”, the required disk capacity data file is CD-
Since it is prepared in advance as a file in the ROM, the contents of the file are searched and the numerical value of the portion corresponding to the corresponding installation condition is set as the required disk capacity. For example,
When installing app_1 and app_3, in the files shown in FIG. 3, app_1 and app_
The required disk capacity is the numerical value of 49,333 bytes in the row of 3.

"Determine file storage order (step S1
4) ”, according to the present embodiment, the installation order data file is prepared in advance as a file in the CD-ROM for each installation condition, and therefore follows the contents of the installation order data file of the corresponding installation condition.

When the above preparation is completed, "an unused continuous area is secured (step S15)". Capacity securing unit 14
The specific securing procedure of will be described with reference to the flowchart of FIG.
The size of the required continuous unused area is the capacity obtained in the "calculation of required disk capacity (step S13)" in the above process.

As shown in FIG. 5, first, the record use status of the VTOC is checked to check whether there is a continuous unused area corresponding to the required capacity (step S2).
0).

If a continuous unused area corresponding to the required capacity is found, that portion is secured as an installation area and this process is completed (step S23). On the other hand, if the necessary continuous unused area cannot be detected, the VTOC next checks whether there is a continuous area of the required disk capacity in the unused record or the record used by the file having no read-only attribute ( Step S21).

If the corresponding area cannot be detected, the installation of the present invention is abandoned and the program is installed by the conventional method (step S24). Further, the installation process may be temporarily suspended to prompt the user to delete unnecessary files.

If found, the data recorded in the record used as a file in that area is moved to an unused area outside the area to be secured at the same time, and at the same time, the corresponding file in the VTOC. The record position referred to by is rewritten to the new transfer destination (step S
22). By applying this work to the entire area to be secured, the step of securing an unused continuous area is completed (step S23).

Then, as shown in FIG. 3, in the "file transfer in consideration of order (step S16)", the order of the files obtained in the "determination of file storage order (step S14)" step, that is, the corresponding According to the order described in the "installation order data file", the reserved unused continuous areas are stored in record units without any gaps.

Finally, the file transferred to the disk-shaped storage medium is given a read-only attribute with respect to the file attribute described in the VTOC.

As described above, according to this embodiment and its example, the following effects are obtained. The first effect is that the records of one file read from the storage medium when the installed program is executed are physically continuous, the movement amount of the access arm is reduced, and as a result, the file can be accessed. Since it started
It takes less time to finish reading the file,
As a result, the program execution speed is improved. The second effect is that the files included in the installed program are placed together in a continuous area of the disk-shaped storage medium, so the records of the files that are called by each other when this program is executed must be recorded during installation. It exists in the secured area and the movement amount of the access arm moves within this range. As a result, the execution speed of the installed program is improved.

A third effect is that, as a place for storing files in a disk-shaped storage medium at the time of installation, it is considered that files having a large correlation with each other are brought close to each other. When reading a required file, etc., it becomes possible to access with a movement smaller than the movement amount of the access arm expected in the second effect, and as a result, the execution speed of the installed program can be increased. It is to improve.

As a fourth effect, by setting the once installed file group as read-only, the speed of executing this program semipermanently can be maintained high.

[0053]

Since the present invention is constructed and functions as described above, according to the present invention, in the invention according to claim 1, the installation control means executes the program after the capacity securing section secures a continuous free capacity. Because of the installation, when the program is executed, the files necessary for execution are read with a small amount of head movement, and therefore,
It is possible to provide an unprecedented excellent program installation device capable of shortening the program reading process required for starting a program.

According to the second aspect of the present invention, the order-based installation unit installs the program data in a continuous free area in a state in which files having a high correlation are arranged in a close order according to the file order information. A file can be stored contiguously, which improves the speed of execution when the file is referenced during program execution, yet installs in contiguous free space, thus creating this correlation. Conventionally, when storing a file in a close area, the application developer can perform the program data file ordering relatively simply without considering the actual configuration of the disk medium. It is possible to provide an excellent program installation device that does not exist.
