Abstract

PURPOSE:To shorten the time of access to file label information by putting the file label of a temporary file on a memory and then referring to and updating file label information on the memory. CONSTITUTION:A temporary file base allocating/releasing means 6 secure a file area on a shared space 3 as much as required and registers label information for controlling the name and position of a file in a label information storage means 5. When the label information is confirmed by a file label information input/output means 7, the volume content table in a storage volume 1 is not referred to and the file name of the temporary file is used as a key to read the label information out of a label information storage means 5 and pass it to a job. Further, when an update request for the label information is inputted from the job to a file label information input/output means 7, corresponding label information is the label information storage means 5 is updated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides a 4kf temporary file stored in a file storage device.
) 7-aisle label information management system.

[Conventional technology]

Conventionally, the file label of a temporary file created in a polynomial on a file storage device is stored and managed in a volume content table on a storage polynomial. Points] The conventional method described above has the disadvantage that when processing file label information, input/output to the storage polyneme occurs, resulting in a delay in program processing time and, as a result, reducing the processing efficiency of the entire system. There is.

[Means for solving problems]

The method of the present invention includes a free space storage means for storing the size of a free space in a shared space within an external storage polyne and its starting position.

a shared space allocation/release means for allocating or deleting the shared space to an external storage system and updating the free space storage means accordingly; a label information storage means for storing file label information of the shared file; When there is a request to store or delete a temporary file, the temporary file space is allocated or deleted in the shared space based on the storage contents of the free space storage means L and the label information storage means, and the free space storage means is also used to store label information. The present invention is characterized by comprising a temporary file space allocation/release means for updating the temporary file space allocation/release means, and a file label information input/output means for accessing the label information storage means when there is a request for access to the file label information of the temporary file.

〔Example〕

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.

Referring to FIG. 1, one embodiment of the present invention provides a storage system in which a shared space 3 is reserved.

Shared space allocation/release means 2, free area storage means 4, label information storage means 5. It consists of temporary file space allocation/release means 6 and file label information input/output means 7.

The shared space 3 is a companion area for storing temporary files associated with the disk, and the storage volume l is also an area for storing fixed files and information for managing the entire storage polyneme 1. It has a volume contents table in which n is stored.

The label information of the temporary file stored in the shared space is stored in the label information storage means 5 realized by memory, and is not stored in the polygon content table.

In response to the input of JCL, the shared space allocation/release means 2 secures a shared space 3t in the memory policy, releases it to TFC, and uses this method to secure or release the shared space 3. depending on.

The size of the empty @ area of the shared space 3, its starting position, and money are written in the empty area storage means 4 realized by memory.

The temporary file space allocation/release means 6 allocates temporary file space in the shared space 3 in response to an instruction from the zipper, releases this temporary file space, and responds to the 'l@anxious area'. The storage means 4 and the label information storage means 5 are all updated. The file label information input/output means 7 accesses the label information storage means 5 in response to an instruction from the zipper, and refers to or updates the label information. 0 Next, the operation of the present invention will be explained with reference to the drawings. 0 When attempting to use a temporary file that frequently opens or closes files, the user must:
A shared space 3 is secured in the storage polyisland 1 using the shared space allocation/release means 2t. At this time, the free space storage means 4 stores the size of the free space in the shared space 3 and its starting position. If much of the memory space 1 is being used by others and the desired shared space 3 cannot be obtained, the jump will end abnormally.

Next, when the storage polyme 1 is requested to create a temporary file from the zipper, the temporary file space allocation/release means 6 determines whether or not the shared space 3 exists in the storage polyme 1. Judgment is made by referring to the free space storage means 4''Ik#◎ -El When the file space allocation/release means 6 recognizes the existence of the shared space 3, it refers to the free space storage means 4 and allocates the amount of money in the shared space 3. Check whether there is enough free space to satisfy the request. Since the common space 3 itself did not exist, the request form was not satisfied. Look for areas other than shared spaces.

In addition to this confirmation, the temporary file space allocation/release means 6 also confirms that the file name of the temporary file is not already stored in the label information storage means 5. The same label information is already registered in the label information storage means 5 for the lifting platform.

Terminates abnormally by trying to prevent the creation of duplicate temporary files.

Temporary file space allocation/release means 6. If the above confirmation is satisfied, a label information at-label information storage means that secures the requested file area in the shared space 3, and manages file names, file area positions, etc. Register for 5. At this time, the free leaning storage means 4t is updated with the amount of remaining free space in the shared space 3.

After that, when the file label information input/output means 7 is requested by the developer to refer to the label information of the temporary file, the file label information input/output means 7 checks whether the shared space 3bN exists in the storage polynym l or not. Leaning memory means 4t
l - Confirm the reading process O When the label information is confirmed by the file label information input/output means 7, the conventional method does not refer to the polyneme content table in the memory polyneme l, but reads it in the temporary file. The label information is read out from the label information storage means 5 using the file name as a key, and is delivered to the zipper. When Yasugi updates the label information from the zip to the file label information input/output means 7, the corresponding label information in the label information storage means 5 is updated. [Effects of the Invention] As explained above, 7? In particular, the present invention places the file label of a temporary file in memory so that the file label information can be referenced and updated on the memory, thereby reducing the access time to the file label information. This has the effect of speeding up program processing time.
