JPS6257040A - Automatic maintenance recovery system for information processing data - Google Patents

Abstract

PURPOSE:To attain the recovery at a required point of time and the automatic maintenance of an information processing data completed on a data base by providing a registration list of processing program names of an information processing data and a management list for information processing data names stored already. CONSTITUTION:Whether a program loaded to a CPU 13 is registered or not in the processing program name registration list 12 of information processing data at first in a routine processing. As a result, when the program is registered, the execution of program is reserved and whether or not the information processing data being the processing object is reserved in a storage medium 14 is decided by a management list 15 for names of information processing data stored already. As a result, the data is not reserved, the data is stored in the medium 14 and its name or the like is registered in the management list 15. When the result of decision is stored already, whether or not the data exists on the data base 11 is decided and when not in existence, the data in the medium 14 is recovered on the data base 11 via the management list 15. Thus, the information processing data completed on the data base 11 is preserved automatically and the required point of time is recovered in this way.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to preservation/recovery of information processing data, and in particular to an information processing system that performs predetermined processing for each information processing data created on a database. The present invention relates to an automatic preservation/recovery method for information processing data suitable for.

[Background of the invention]

Generally, due to the importance of information processing data, its preservation is an important issue, but the maintenance work itself is often not directly related to daily business processing. Therefore, depending on the information processing data, there is a possibility that some data may not be preserved, and since it takes a lot of man-hours and it is difficult to select the data that should be preserved, it may be inefficient to preserve all the data and the storage becomes complicated.
There is a problem. A known example of data preservation/recovery technology is disclosed in Japanese Patent Laid-Open No. 55-67849. This known example saves update information when data is updated, and facilitates searching for a medium in which update information is saved at the time of restoration.

[Purpose of the invention]

An object of the present invention is to automatically store information processing data in another medium when the information processing data is completed on the database and use it, and to automatically restore the information processing data to the busy database when it becomes necessary. The objective is to provide an automatic data preservation/recovery method.

[Summary of the invention]

Information processing data contains important information, and must be stored in a medium other than the database medium used in normal processing so that it can be recovered when necessary. The present invention is characterized by automating the storage and recovery work of information processing data by linking the routine processing of completed information processing data with the storage or recovery of the information processing data.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail using the drawings. FIG. 1 is a block diagram showing the configuration of this embodiment, and FIG. 2 is a flowchart showing an example of operation.

, 1'F1, numeral 11 is a database for creating, updating, and storing information processing data, and serves as an input for a program that uses the information processing data.

Reference numeral 12 denotes a register in which, among the programs that use the information processing data on the database 11, names of programs that generate an opportunity for preservation 1 recovery of the information processing data at the time of execution are registered. Reference numeral 13 denotes a central processing unit, in which various programs including programs for preserving and restoring information processing data and programs registered in the register 12 are executed.

Reference numeral 14 denotes a storage medium for maintaining and preserving the information processing data on the database 11 and for restoring the information processing data to the database 11. Reference numeral 15 denotes a management book in which the names and update history numbers of information processing data stored in the storage medium 14 are recorded, and is used to determine whether or not the information processing data on the database 11 is stored in the storage medium 14. used for 16 is a program library, which stores programs used in this information processing system;
It is loaded into the central processing unit 113 and executed. Next, an example of the operation of this embodiment will be explained.

It is determined whether the program loaded into the central processing unit 15 is registered in the register 12 in which the name of a specific program that processes information processing data is registered (step 2
2). If the determination result in step 22 is that the program is not registered, the loaded program is executed without preserving or restoring the information processing data. If it is registered in step 122, the execution of the loaded program is suspended and the information processing data to be processed is stored on the storage medium 1.
It is determined whether or not the saved information processing data has been saved in 4 using the management book 15 in which the name and update history number of the saved information processing data are recorded (step 23). If it is determined in step 23 that the information processing data to be processed has not been saved, the information processing data is
4 and register its name and update history number in the management register 15, the maintenance processing program is loaded into the central processing unit 15, and after execution is completed, the program pending execution is executed in step 23 (step 25.27). ). If it is determined in step 23 that the information processing data to be processed has been saved, the pending program is executed in step 23, and the information processing data exists on the database 11 due to open processing to the information processing data to be processed. Determine whether or not (
Step 24). If it is determined in step 24 that the processing target information processing data exists on the database 11, then in step 24 the execution of the program being executed is continued. If it is determined in step 24 that the information processing data to be processed does not exist on the database 11, execution of the program in step 24 is inhibited again, and after checking the name and update history number of the information processing data in the management list 15, After restoring the information processing data in 14 onto the database 11, execution of the execution suppression program is resumed (step 2427).

As described above, according to the non-embodiment, the preservation and recovery of information processing data on the database is automatically carried out at the necessary time.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, it is possible to securely maintain the completed information processing data even when carrying out daily business processing, and the information processing data can be stored at the time of need. can be restored, preventing omissions in maintaining information processing data, automating maintenance and recovery, reducing work man-hours, and preserving information processing data after completion, so it can be used immediately after recovery; This has the effect of significantly reducing management man-hours.
