Abstract

PURPOSE:To reduce man-hours required for resource management by effectively performing the resource management of a magnetic disk, and reducing a part for which manual work is interposed. CONSTITUTION:A managing record including the number of times of access for each file of a magnetic disk device 9 is stored in a managing filing device 8, and the number of times of access is updated and estimated by access information from a file access monitoring means 1. An automatic update processing means 2 starts up update processing at a date set by an operator, and extracts the file in which the number of times of access shows zero, and outputs a list. After the content of an extracted file is saved to an MT by a data saving means 3, a file deletion means 4 delets the file. The re-arrangement of a residual file and the re-configuration of the disk are performed by a file re-arrangement/ re-configuration means 5, and a summary list is outputted. After a series of processing is completed, a managing file update means 7 updates the managing filing device 8. A file information input means 6 inputs the information of a newly generated or deleted file when the file is newly generated or deleted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic disk resource management system.

[0002]

2. Description of the Related Art A conventional magnetic disk resource management system is, as shown in FIG. 3, a file usage monitoring means 11 for collecting file usage records, a data file device 13 for storing the collected records, and a storage. The file use status output means 12 for outputting the selected record to the printer of the terminal.

The file usage status monitor means 11 is provided in the operating system of the computer, and a file usage status record is time-series data file each time each file of the magnetic disk device is accessed (file open / close). Output to the device 13. The records input to the data file device 13 are output to the printer in the same time series order as when input by the file usage status output means 12.

The system operator who manages the magnetic disk resource of the computer confirms the number of times of use for each external file name based on the record list output from the printer when the magnetic disk resource is insufficient, I'm working on finding and deleting unnecessary files.

[0005]

In the above-mentioned conventional magnetic disk resource management method, when the capacity of the magnetic disk becomes insufficient, the record list including only the accessed file name output from the file usage status output means is used. However, there is a drawback that it takes a lot of man-hours and time to judge a file that may be deleted and delete the file because the file that should be deleted is checked by checking the file that seems to be unnecessary.

The object of the present invention is to reduce human intervention,
Moreover, it is to provide a magnetic disk resource management method capable of effectively utilizing magnetic disk resources.

[0007]

SUMMARY OF THE INVENTION A magnetic disk resource management system of the present invention is a management file device storing a management record containing the access count set for each file on a magnetic disk device, and file access information. And a file access monitor means in the operating system for adding the access count of the corresponding management record, and a deletion to be started based on the access count of the management file device which starts operation at a set date and time. An automatic update processing means for selecting a target file and creating an access status list; a data saving means for saving the data of the deletion target file to a magnetic tape; and a file deleting means for deleting the deletion target file after saving the data, Remaining after deletion by referring to the management record of the management file device File relocation disk reorganization means for relocating files and reorganizing magnetic disks and outputting a file list list; file information input means for acquiring and inputting information on newly created files and deleted files; and when creating new files And management file updating means for updating the management file device after deleting the file to be deleted.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of an embodiment of the present invention.

The magnetic disk resource management system of this embodiment is
As shown in FIG. 1, file access monitor means 1, automatic update processing means 2, data save means 3, file deletion means 4, file relocation disk reorganization means 5, file information input means 6, management file update means 7, The management file device 8 and the magnetic disk device 9 are included.

The file access monitor means 1 is incorporated in the operating system and monitors the access status to each file of the magnetic disk device 9,
The information is output to the management file device 8.

The management file device 8 stores a management record for each file of the magnetic disk device 9 in a record layout as shown in FIG. 2, and the access information from the file access monitor means 1 determines the file The access count of the management record is added and accumulated. The management flag is set for important files and the like that are excluded from the targets of automatic updating.

The automatic update processing means 2 starts the file update processing according to the date and time set by the system operator, and the number of accesses is 0 from the management records registered in the management file device 8. Select the corresponding file as the file to be deleted (excluding the file for which the management flag is set), and record the external file name, media name (magnetic disk device identification name), etc. Output as.

The data saving means 3 saves the data in the file to be deleted selected by the automatic update processing means 2 to the magnetic tape (MT). After saving the data, the file deleting means 4 deletes the corresponding file in the magnetic disk device 9.

The file relocation disk reorganization means 5 is
After deleting the file to be deleted, the management record of the management file device 8 is referenced to relocate the residual file within the same magnetic disk, and if necessary, reorganization across magnetic disks according to a predetermined standard. By doing so, the file storage efficiency is improved.

When a new file is created, the file information input means 6 delivers information (external file name, etc.) regarding the file necessary for the resource management to the management file update means 7. Even when a file is deleted, that information is passed.

The management file updating means 7 updates the management record of the management file device 8 when a new file is created or a file is deleted.
Also, each time the above-described series of update processing by automatic update is performed, the access count of each management record of the management file device 8 is reset to zero.

[0018]

As described above, according to the magnetic disk resource management method of the present invention, the management file device stores the management record including the number of times of access to each file of the magnetic disk device, and based on the number of times of access of the management record. , Selection of files to be deleted, data saving (MT replacement is done manually), file deletion, file relocation and magnetic disk reorganization are performed automatically, reducing the man-hours required for magnetic disk resource management There is an effect that it can be effectively used.
