JPH05313830A - Retrieving system for generation control file - Google Patents

Abstract

PURPOSE:To attain the automatic production of a prior list of the generation- controlled magnetic tapes, e.g. those tapes to be used on the relevant day. CONSTITUTION:The information (the number of generations, the file names and the medium names) on the generation-controlled magnetic tapes given from a generation file register card 15 are registered into a generation control file (a) 17a in advance by a generation file information register function 16. An access is given to the file 17a by a generation control file retrieving function 18, and the next generation of the designated file is retrieved. Then, the retrieved file names and the medium names of the subject magnetic tapes are outputted as a magnetic tape use list 19 of the retrieving result list examples. Thus, the manual control is omitted and the writing mistakes can be reduced for the medium names of the magnetic tapes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generation management file retrieval system, and more particularly to a magnetic tape medium name retrieval system corresponding to a designated file name.

[0002]

2. Description of the Related Art A conventional generation management file search method for files such as magnetic tape will be described with reference to the drawings.

FIG. 2 is an image diagram of a management ledger of a conventional generation management file, and FIG. 3 is a schematic configuration diagram of a system using a conventional generation management file search method.

Referring to FIG. 3, the conventional generation management file retrieval system has a generation file registration magnetic tape 11, a generation file magnetic tape medium name 12, a generation file name 13, a generation 14, and generation file information. It is composed of a registration card 15, a generation file information registration function 16, and a generation management file b17b.

Next, the operation of the conventional generation management file search method will be described with reference to the drawings.

In the conventional magnetic tape generation management, when the job is executed, the generation management file b17b shown in FIG.
And ask the operator for the media name of the magnetic tape to be used this time for the specified file, or
As shown in FIG. 2, information about generation management of magnetic tapes registered in advance is entered and managed in a ledger, and manually prepared, for example, a magnetic tape to be used on the day.

[0007]

In the above-mentioned conventional manual generation management, there is a troublesome work of creating a management ledger and, for example, entering the medium name of the magnetic tape used on the day, and the attendant entry is required. There is a problem that mistakes occur.

An object of the present invention is to access a file in which information on generation-controlled magnetic tape (number of generations, file name, medium name) is registered in advance, search for the next generation of the specified file, The generation management file search method that eliminates the above-mentioned drawbacks by eliminating the need for manual management by outputting the result of the name and the media name of the target magnetic tape, and reducing the time and error of entering the media name of the magnetic tape. To provide.

[0009]

According to the generation management file search method of the present invention, a file in which a medium name of a magnetic tape for generation management, a file name of data to be stored in the magnetic tape and the number of generations are registered, and a file is input. Then, it has a function of acquiring the medium name of the next-generation magnetic tape of the specified file name and outputting the result.

[0010]

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

FIG. 1 is a schematic configuration diagram of a system using a generation management file search method according to an embodiment of the present invention.

Referring to FIG. 1, the generation management file search system of this embodiment includes a generation file registration magnetic tape 11, a generation file magnetic tape medium name 12, a generation file name 13, a generation 14, and a generation file. Information registration card 15, generation file information registration function 16, generation management file a17a, generation management file search function 1
8 and a magnetic tape list 19 which is an example of a search result list
It consists of and. Next, the operation of the generation management file search method of this embodiment will be described with reference to the drawings.

Generation files to be registered as a generation file Magnetic tapes M1, M2 and M3 having a magnetic tape medium name of 12 are named A. B. It shall be used cyclically at C.

Therefore, in the generation management file a17a,
File name A. B. C, magnetic tape medium names M1, M
2, M3 and generation number 3 for generation file information registration function 1
Use 6 to register. Then A. B. When the management file search function 18 is executed by designating the file name of C, the generation management file a17a is accessed and, for example, a list 19 of magnetic tapes used on the day is output.

That is, the information (number of generations, file name, medium name) of the generation-managed magnetic tape from the generation file registration card 15 is registered in advance in the generation management file a17a by the generation file information registration function 16, and the The registered file is accessed by the generation management file search function 18, the next generation of the specified file is searched, and the result of the file name and the medium name of the target magnetic tape is used as the magnetic tape usage list 19 of the search result list example. Output.

Here, the generation file information registration card 15
Is created using the catalog maintenance JCL in the source library in TSS, for example. Also, generation 14
Is the number of generations and the timing of cyclic.

[0017]

As described above, in the generation management file search method of the present invention, since the used medium name of the magnetic tape under generation management is searched, no human labor is required, and for example, it is used on the same day. When there are a large number of magnetic tapes to be prepared, there is an effect that the time required to prepare the list for the advance preparation is extremely shortened and the prepared magnetic tapes can be secured without error.
