Abstract

PURPOSE:To prevent a waste of a file system due to forgotten erasure, etc., by automatically deleting a file and a directory, which are created on the file system where a temporary file attribute is set, by the system. CONSTITUTION:This device has a temporary file attribute setting means 1 which sets attributes, a file/directory creation means 2 which outputs temporary file information, a temporary file information recording means 3, and an execution state monitor device 4. The execution state monitor means 4 monitors the execution state of a job and a session at a request source and reports execution end information at the end. A temporary file deleting means 5 receives the execution end information, retrieves a temporary file and a directory created with the indication of the request source in the temporary file information recorded in the temporary file information recording means 3, and deletes the found file and directory. Therefore, even if a user forgets to erase them, they are automatically deleted at the end and the effective utilization of the file system is never impeded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary file management device in a computer system that uses a plurality of hierarchical file systems.

[0002]

2. Description of the Related Art In a conventional temporary file management device of this type, a creator needs to delete files or directories that are temporarily necessary by himself / herself when unnecessary.

[0003]

In the conventional temporary file management device described above, if the creator forgets to delete the file, unnecessary files and directories will remain in the file system, which hinders effective use of the file system. There is a problem that there is.

[0004]

The device of the present invention is a temporary file management device in a computer system using a plurality of hierarchical file systems, and temporarily sets an attribute as a file system for temporary files in an arbitrary file system. A file attribute setting means and a file or directory are created on the specified file system, and if the file system has the above attributes, temporary file information including the created file or directory and the request source for creation is output. File / directory creating means, temporary file information recording means for receiving and storing the temporary file information, execution state monitoring means for monitoring the execution state of the request source job or session, and notifying the execution end information at the end Receiving the execution end information The temporary file deleting unit searches the temporary file information and the directory created by the instruction of the requester from the temporary file information recorded in the temporary file information recording unit, and deletes the found file and directory. Temporary file management device. Characterize.

[0005]

In the present invention, the files and directories created on the file system with the temporary file attribute set are automatically deleted by the system at the end of execution of the request source even if the user forgets to delete them. , It does not remain on the file system, and the effect of preventing the effective use of the file system from being hindered can be expected.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, which is a block diagram of an embodiment of the present invention, this embodiment is a temporary file attribute setting means 1 for setting an attribute as a file system for temporary files in an arbitrary file system, A file / directory creating unit 2 which creates a file or directory on the created file system and outputs temporary file information including the created file or directory and the creation request source when the above attribute is set on the file system. A temporary file information recording means 3 for receiving and storing the temporary file information; an execution state monitoring means 4 for monitoring the execution state of the request source job or session and notifying execution end information at the end; and the execution end information. The temporary file and directory created by the requestor's instructions. The birds were retrieved from the temporary file information recorded in the temporary file information recording unit 3, and a temporary file deletion unit 5 deletes the files and directories found.

FIG. 2 shows an example of the status of the attributes set by the temporary file attribute setting means 1 in FIG. The name is a path name on the mounted root file system of the file system, and the file system indicated by tmp in the attribute column has the temporary file attribute set.

FIG. 3 shows an example of temporary file information recorded in the temporary file information recording means 3 in FIG.
The temporary file information is recorded separately for each file creation request source.

FIG. 4 shows an example of a temporary file attribute setting request, and FIG. 5 shows an example of a file and directory creation request when the request source is a batch job.

The operation of this embodiment will be described below with reference to FIG.

When a temporary file attribute setting request as shown in FIG. 4 is input, the temporary file attribute setting means 1
The specified file system is mounted on the root file system and the temporary file attribute is set on the file system as shown in FIG.

Next, when a batch job as shown in FIG. 5 is executed, files and directories are created by the commands (1), (2) and (3) in FIG. Instructed by means 2.

The file / directory creating means 2 creates the instructed file or directory, and when the created position is on the file system having the temporary file attribute, the path name of the created file and the batch job requesting the creation. Is notified to the temporary file information recording means 3.

In the case of the example of FIG. 5, since the file is not created on the file system having the temporary file attribute in (1), nothing is notified to the temporary file information recording means 3. However, both (2) and (3) create a directory and a file respectively on the file system in which the temporary file attribute of FIG. 4 is set, so the batch job ID = 100 and its path name are stored in the temporary file information recording means 3. (/ Tmp / tmp_fsl / work_dir and / tmp / tmp_fsl / work_dir / tm
p_file) is notified.

The temporary file information recording means 3 receives the above notification and records the path name of the file or directory created for each request source as the temporary file information as shown in FIG.

On the other hand, the execution status monitoring means 4 monitors the execution status of each batch job, session, or other source of a temporary file creation request, and if there is a batch job that has finished executing, its ID is sent to the temporary file deletion means 5. Notice.

Upon receiving the notification from the execution status monitoring means 4, the temporary file deleting means 5 searches the temporary file information recorded in the temporary file information recording means 3 and creates a batch job whose execution has been completed. Examine temporary files. If the temporary file exists, the file and the directory are deleted, and the temporary file information recording means 3 is notified of the deletion.

The temporary file information recording means 3 that has received the deletion completion notice from the temporary file deletion means 5 deletes the information regarding the deleted files and directories from the held temporary file information.

[0019]

As described above, according to the present invention, files and directories created on a file system in which an administrator has set a temporary file attribute are automatically generated by the system, even if a general user is not particularly aware. Since it is deleted, the file system is effectively prevented from being wasted due to forgetting to erase it.
