Abstract

PURPOSE:To initialize a magnetic tape medium neither too much nor too little by outputting a message to request initializing the magnetic tape medium by the number of shortage when there is no magnetic tape medium to be assigned because all the magnetic tape media are still within their preservation periods. CONSTITUTION:A medium registering initializing means 1 adopts the magnetic tape medium serial control numbers of the magnetic tape media of the number portion of the purchased media in conformity to the instruction of a registering initializing commanding means 4, and registers them in a file management master data base 5, or initializes an initializing magnetic tape medium 6. Then, the contents of the file management master data base 5 are updated by considering the purchased magnetic tape media as the initialized media. When there is no medium to be assigned in the file management master data base 5, a JCL pre-analyzing means 3 assigns the name of the medium to be newly added, and outputs the purport of the execution of the medium registering initializing means 1 to a monitor list 9. Thus, duplicated initialization by the name of the same medium can be prevented.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a management method for magnetic tape media, and in particular to a method for initializing magnetic tape media and managing the allocation of writable magnetic tape media to output files. .

(Journey's technology) Conventionally, when managing magnetic tape media, the media name after initialization is recorded in the management ledger, and from there, a writable magnetic tape media is assigned to the output file, and the file name and save are recorded. It was managed by describing the period. Furthermore, if files were to be created using the same file name, it would be possible to automatically allocate files by using generation management means and circulating magnetic tape media.

(Problem to be Solved by the Invention) In the conventional management system described above, omissions in the media name and file name of the magnetic tape medium occur in the management ledger.
This method has the drawback that human management errors may occur, such as the same media name existing twice or a file that needs to be saved being destroyed by another file.

When the generation management means is used, output is allocated to the oldest generation magnetic tape medium due to cyclic use, so there is a drawback that files output to that medium may be destroyed. Therefore, in order to avoid this problem, the number of generations must be changed and another magnetic tape medium must be newly allocated.

The purpose of the present invention is to register the number of magnetic tape media and the serial management number of the magnetic tape media corresponding to the number of magnetic tape media in a database at the time of purchase, and to initialize the registered magnetic tape media as many as necessary. , each is registered in a media group set for each retention period, the file description as an output file is analyzed, and a storage-capable medium is assigned from the corresponding magnetic tape media group based on the file name. If the magnetic tape media is within the retention period and there is no magnetic tape media to be allocated, a message requesting initialization for the number of missing magnetic tape media is output to eliminate the above drawback and ensure that there are no excess or shortage of magnetic tape media. An object of the present invention is to provide a unified management method for magnetic tape media configured to be initialized.

(Means for Solving Problem 1k) A unified management system for magnetic tape media according to the present invention is configured to include a medium registration initialization means and a preliminary JOL analysis means.

The medium registration initialization means registers the number of magnetic tape media and the magnetic tape medium series management number corresponding to the number of media in the database at the time of purchasing the magnetic tape media, and also registers the registered magnetic tape media. This is to initialize the required number of media and register them in media groups set for each retention period.

The pre-JOIj94 analysis means analyzes the file description as an output file, allocates a writable medium from the corresponding media group based on the file name, and assigns the magnetic tape medium that should be allocated because all of the magnetic tape media are within the retention period. This is to output a message requesting initialization for the insufficient number of tape media when there are no tape media.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram showing an embodiment of a unified management system for magnetic tape media according to the present invention.

This embodiment includes a medium registration initialization means 1, an information definition thousand stages 2, a pre-JOL analysis means 3, a registration initial command means 4, a file management master database 5, an initialization magnetic tape medium 6, and definitions. Information file 7 and analysis target JOL
It is configured to include a library 8 and a monitor list 9.

The medium registration initialization means 1, in accordance with the instructions from the registration initialization command means 4, writes magnetic tape medium series management numbers for the number of purchased media. File management mask database 5
or initialize magnetic tape medium 6t-
The contents of the file management mask database 5 are updated by initializing the purchased magnetic tape medium as an initialized medium.

The information definition means 2 registers these in the definition information file 7 by defining the correspondence between subject codes set for each retention period and media groups, as well as the correspondence between file names and media groups.

The preliminary JOL analysis means 3 analyzes the JOL library 8 to be analyzed.
Search and analyze the file description as an output file from among them, determine the medium group by comparing the file name and definition information file 7, select a writable magnetic tape medium from the file management master database 5, and edit. A JOL library 8 to be analyzed is constructed, and a medium information record is registered in the file management mask database 5.

If there is no medium to be allocated in the file management master database 5, the pre-JOL analysis means 3 allocates the name of a new medium to be added, and outputs to the monitor list 9 a notification to the effect that the medium registration initialization means 1 is to be executed.

As shown in FIG. 2 (al), the file management master database 5 includes subject records 51, media group records 52, media name records 53, and media information records 54
It is constructed with the following. The subject record 51Fi is configured as shown in FIG. 2(b), the media group record 52 is structured as shown in FIG. 2(C), and the media name record 53 is configured as shown in FIG. 2(d). The medium information record 54 is structured as shown in FIG. 2(e).

As shown in FIG. 3(a), the definition information file 7 includes a subject code record 71 and a file name record 72. The subject code record 71 is structured as shown in FIG. 3(b), and the file name record 72 is
is S as shown in FIG. 3(C).

The JOL library to be analyzed is structured to include a plurality of subfiles 81, as shown in FIG. 4(a). Subfile 8l is Ig4JOL as shown in Figure 4(b).
It is composed of descriptions.

The JOL description defines a unit of work that uses the operating system t, and information regarding output files can be written in the description.

(Effects of the Invention) As explained above, the present invention makes it possible to closely grasp the state transition of a magnetic tape medium by using a database.
This has the effect of eliminating human operational errors such as duplicate initialization with the same media name and duplicate allocation of magnetic tape media, and making it possible to effectively utilize magnetic tape media.

Furthermore, administrators of magnetic tape media can now use existing utilities or create programs to search the entire database and output the information in the database as a form, allowing detailed management. effective.

In addition, the user of the magnetic tape medium has the advantage that without knowing the name of the medium on which the file contents are to be output, the medium name can be automatically assigned by simply writing the output file name and b<.
