JPH04291637A - Generation selecting system for management data - Google Patents

Abstract

PURPOSE:To make it unnecessary for a user to form the definition of a set of some management data or the directory of the definition in each updating of management data in a method for forming the set of some necessary management data out of plural management data whose generation is managed at the time of using the data. CONSTITUTION:The management data of generation numbers (maximum numbers 26, 27 out of numbers equal or smaller to/than a specified generation number) corresponding to the specified generation number 21 (e.g. 01-02) are automatically selected from plural kinds (DB logical structure 22, DB storage structure 23,...) of management data whose generation is managed based upon management data set definition previously defined by a system. The selected management data 26, 27 are merged with each other to automatically form, register and manage the set (the set of DB structure management data) 25 of required management data.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a generation selection method for management data, and in particular, a generation selection method for management data that supports maintenance and management of management data suitable for creating and managing a collection of management data. Regarding.

0002

2. Description of the Related Art Conventionally, as described in, for example, Japanese Patent Laid-Open No. 62-34230 entitled "Data Dictionary Mechanism," there have been several types of management data (
For example, as a method of creating a collection of various management data such as database logical structure, database storage structure, etc.
A known method is to define each set, create a register in which these definitions are recorded, and register arbitrary management data based on the definition of a certain set.

However, in this method, the registry becomes management data that must be managed by a user who is a system operator, resulting in an increase in the amount of management data.

0004

[Problems to be Solved by the Invention] In the above-mentioned prior art, in order to utilize the management data, it was necessary for the user to define each set of management data and to manage a register containing these definitions. In this method, each time the management data registered in a certain set is updated and the generation is changed, the definition is redone and the register is updated, which creates a management burden.

Therefore, with this method, it is necessary to redefine the set every time the generation is updated, and in order to create several sets of management data, new management data called a register must be added. There were some unavoidable flaws.

[0006] Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks, eliminate the need for redefinition even when a generation is updated, and without increasing new management data called a registry.
The system automatically selects the necessary management data when the user simply specifies the generation as a key, automatically creates a set of several selected management data, and provides a generation selection method for management data to manage data. It's about doing.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the management data generation selection method of the present invention includes means for managing the generations of a plurality of management data, and a number of target data among the management data. Compares the generation number of the management data with the specified generation number and automatically selects the management data with the required generation number (for example, the highest number that is equal to or smaller than the specified generation number) and a management data set creating means that automatically creates a management data set (determining the environment during system operation) by combining (merging) the selected management data.

[0008]

[Operation] The operation based on the above configuration will be explained.

According to the present invention, in the method of modifying a plurality of management data by generation and managing the history thereof, by providing the management data selection means and the management data set creation means described above, it is possible to Instead, the system automatically searches for (selects) target management data using the specified generation number as a key, merges the selected management data, and creates a collection of management data that determines the system environment during operation. ) automatically generated. In addition, this search and merging of management data is automatically performed according to the system's predefined management data set definition (for example, which management data should be combined with which management data) and the generation selection number, so the user can search and merge them one by one. It is not necessary to create a table definition for , nor is it necessary to update the definition. In addition, the system automatically creates a set, and the system also automatically creates a register of the created set and manages it together with the set.
The user does not need to create a register of sets every time management data is updated.

Therefore, it is no longer necessary for the user to create definitions for several sets of management data and register arbitrary management data in the definition of a certain set, as in the past. It becomes possible to create and manage a collection of data without describing or defining it in a registry.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the management data generation selection method according to the present invention.

In FIG. 1, 11 is a data set (management data storage device) for storing management data, 12 is a data set (management data set storage device) for storing a collection of management data, and 13 is a management data storage device. generation management device,
14 is a management data automatic selection device, 15 is a definition of a management data set, 16 is a device for creating a management data set, 1
7 is a device that manages a collection of management data.

The data set 11 that stores management data stores management data for defining the environment of the computer system and managing the devices that make up the computer system. The management data consists of several types, for example, management data of the logical structure of the database, management data of the storage structure of the database, etc. In addition, online management data includes various types of management data such as system environment management data, system environment management data, system environment option management data, and journal acquisition management data. These management data are generation-managed by the management data generation management device 13 in the order of generation of the management data. However, the data set (data storage device)
In No. 11, management data of each type is not merged and stored separately.

The device 12 for storing a collection of management data includes:
By merging several types of management data, several sets of management data necessary when the computer system operates are stored. These management data sets are stored in the device 1 that manages the management data sets.
It is managed by 7.

The management data automatic selection device 14 uses a management data set definition 15 to create a management data set.
According to the type of management data that constitutes the set defined in
Management data is searched from the data set 11 that stores management data. By specifying a generation number as this search condition, management data matching the condition is selected. In this embodiment, in the management data set definition 15, the system defines the set in advance by the name and generation of the management data in the form of a list.

The device 16 for creating a collection of management data includes:
A set is created from the management data selected by the automatic management data selection device 14.

The device 17 for managing a collection of management data includes:
A set of management data created by a device 16 for creating a set of management data is stored and managed in a data set 12 that stores a set of management data.

FIG. 2 shows the relationship between several pieces of management data when a set is created by the generation selection function.

21 shows the flow of generations by generation numbers. 22 and 23 indicate the generation flow of each management data forming the set. In this example, 22 indicates management data for the logical structure of the database, and 23 indicates management data for the storage structure of the database. 24 indicates a set of management data of a database structure selected from the management data of 22 and 23.

[0021] A set of 25 management data can be created by specifying generation selection numbers 01-02 and using these numbers as selection conditions.
It is created by selecting logical structure management data 01-00 of No. 6 and storage structure management data 01-02 of No. 27.

The procedure for creating a set of management data using the generation selection function will be explained in more detail based on the flowchart of FIG. 3 and with reference to FIG. 2.

When performing a generation selection operation, read the type of the specified management data set, for example, the management data 22 of the database logical structure and the management data 23 of the database storage structure (step 101), and register it in advance. From the definition 15 of a certain set of management data, the definition of a set of management data corresponding to this type, for example, the set that the management data 22 of the logical structure of the database and the management data 23 of the storage structure of the database must match. Read the definition (step 102).

Furthermore, when performing a generation selection operation, the specified generation selection number, for example 01-02, is read (step 103).

Next, based on the definition of the read management data set, management data to be registered in the set is searched from the data set 11 that stores management data. for example,
The entire management data 22 of the logical structure of the database in the dataset 11 (01-00, 01-03, and 02
-00) and the entire management data 23 of the database storage structure (01-00, 01-01, 01-02, 01-0)
3, and 02-00) (step 104)
. At this time, the generation number of the searched management data, for example, the generation number of the entire management data 22 of the database logical structure, the generation number of the entire management data 23 of the database storage structure, and the generation specified when performing the generation selection operation. Management data with the largest generation number (for example, management data of the logical structure of the database with generation numbers 01-00) among those that are equal or smaller than the selection numbers (for example, 01-02) 26 and generation number 01-
The management data 27 of the storage structure of the database No. 02 is selected (step 105).

The selected management data is registered in the set (step 106), and the same process is performed for other management data defined in the definition of the management data set, and the processing for the defined management data is completed. (Step 107)
) Later, the registered management data set is also determined (step 108) and stored in the data set 12 that stores the management data set.

[0027]

[Effects of the Invention] As explained in detail above, according to the present invention, in a method for managing generations of a plurality of management data,
In order to create and manage a set of management data that determines the system environment during operation, the system automatically selects management data according to the management data set definition defined in advance and the specified generation selection number, and selects the selected management data. Since the set of management data is automatically generated and managed, the user can create the necessary set of management data without having to write definitions to select management data each time a set of management data is created. This has the effect of improving operability and efficiency in system development, operation, and maintenance.
