Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a data processing apparatus that searches for resources and executes data processing, and more particularly, to enabling disclosure of a preset resource search environment. The present invention relates to a data processing apparatus that enables a program or the like that executes individual data processing to use the resource search environment.

In executing data processing, it is necessary for individual programs that execute data processing to set and manage a resource search environment. Also, even when developing a program, it is necessary for each developer of the program to set and manage a resource search environment. Such a process of setting and managing the resource search environment places a burden on individual programs and imposes a considerable burden on program developers. Therefore, measures should be taken to reduce such loads. We have to go.

[Conventional technology]

Next, a method for setting a resource search environment in a conventional data processing system will be described with reference to an example of program development.

When executing program development, set up and manage a search list that determines the priority of paths when searching for general files, executable files, commands, etc., and a resource search environment consisting of resource name replacement information, etc. There is a need to continue to. Conventionally, the developers of the program development individually set and manage the resource search environment. In other words, each developer creates a resource search environment suitable for the program to be developed on the spot, or creates and saves a resource search environment that is often used in advance, By selecting from among them, the user personally sets and manages the resource search environment.

[Problems to be solved by the invention]

Indeed, if the tasks for program development are completely different, or if different resources are used for the same task, the developers of the individual program developers set up and save the resource search environment. I have to do it. However, in the case where the tasks for which the program is to be developed are the same, and the scope of the resources to be used is fixed (hereinafter, sometimes referred to as routine tasks), the resource search is performed. In spite of the fact that the environment can be shared, conventionally, the setting and management of the resource search environment has been left to individual developers as in the case of general program development. From now on, with the conventional technology, there is a problem that the program developer's labor is duplicated in the routine business program development, and that the load of each developer is increased. there were.

Such a problem that the setting and management of the resource search environment that can be shared is entrusted to each individual exists not only in program development but also in general data processing systems.

The present invention has been made in view of such circumstances,
Make it possible to publish a preset resource search environment,
It is an object of the present invention to provide a new data processing device that solves such problems that the conventional technology has by making a program or the like that executes individual data processing use the resource search environment. .

[Means for solving the problem]

 FIG. 1 is a diagram illustrating the principle of the present invention.

In the figure, 1 is a data processing device equipped with the present invention, 2 is a DASD provided in the data processing device 1, which manages files and the like which are resources for data processing, and 3 is a device provided in the data processing device 1. A resource management resource, 10 is a directory management unit that manages directories according to a tree structure, and 11 is a directory storage unit, which expands a directory 20 stored on DASD2. Reference numeral 12 denotes a business directory constituting a tree structure of a directory, which is provided as a directory related to data processing of a specific business, and 13 denotes a storage and retrieval environment managed by each business directory 12, 14 is a resource search environment stored and managed in a tree structure, and 14 is resource information used by each business directory 12. Those that identify resources,
Reference numeral 15 denotes a resource search environment setting processing unit that executes a resource search environment setting process for the directory management unit 10, 16 denotes an application processing unit that issues a resource search request, and 17 denotes a resource search request. The search unit searches for resources in response to a resource search request issued by the application processing unit 16.

This stored search environment 13 is, if necessary, a stored search environment 13 managed by the business directory 12 located at a higher level than the stored search environment 13.
Is configured to indicate whether or not the search is necessary.

[Action]

In the present invention, the resource search environment setting processing unit 15 registers the resource search environment for which the setting request is made in the directory management unit 10 in response to a request from, for example, a program development manager. As a result, the resource search environment relating to the business is stored as the storage search environment 13 in the business directory 12 of the business to be developed in the directory storage unit 11.

When the application processing unit 16 wants to search for a resource using the stored search environment 13 registered in this way, the application processing unit 16 requests the search unit 17 to specify the business directory 12 of the business related to the data processing and search for the resource. Issue In response to the search request, when the business directory 12 is specified, the search unit 17 specifies the stored search environment 13 under the business directory 12 as a resource search environment required by the application processing unit 16, and the specified According to the saved search environment 13, processing is performed to search and set which resource is requested by the application processing unit 16.

As described above, according to the present invention, the resource search environment that can be standardized for each business unit of data processing is configured to be registered as a resource in the directory, so that the resource search environment can be disclosed and used freely. Developers and application programs of program development who can directly use the resource search environment do not need to create and set the resource search environment by themselves.

Further, in the present invention, when the resource search cannot be realized in the storage search environment 13 specified as described above, the search unit 17 determines whether the storage search environment 13 needs to search the upper storage search environment 13. When there is a display, processing is performed to search and set which resource is requested by the application processing unit 16 in accordance with the higher-order stored search environment 13.

As described above, according to the present invention, since it is possible to specify the continuation of the search in the higher order in the stored search environment 13 having the upper and lower relations, the system using the resource search environment registered in the directory can be used in the system. It is not necessary to specify the resource name according to the unique identifier, and the description of the resource name can be executed according to the easy-to-understand logical name used in the storage / search environment 13 to be used.

〔Example〕

Hereinafter, the present invention will be described in detail according to an embodiment applied to a program development system.

In an OS such as UNIX, as shown in FIG. 6, a directory (management book) of a file system is managed in a tree structure. In FIG. 6, boxes not at the end of the tree structure represent individual directories, and boxes at the end are files in which programs and data are actually stored. The directory located at the root of the tree structure is called a root directory.

In the present invention, a search list (which determines the priority of a path for searching for a general file, an executable file, a command, and the like) and a resource name required for program development are stored in a directory having such a tree structure. The present invention proposes a configuration in which a resource search environment defined by replacement information and the like is incorporated and managed in accordance with a routine business unit for which a program is to be developed. In other words, by realizing the management of the resource search environment by the file management system and publishing it, developers who develop the same routine business program can use the resource search environment in common, It proposes that it is not necessary to create a resource search environment individually.

The setting processing of the resource search environment to be managed in the directory is executed by the business manager who is in charge of managing the development of the routine business program. In other words, the task manager who manages the entire program development related to routine tasks on the developer who develops the specific program develops the resource search environment, and is shared by the developers of individual programs. The resource search environment is set as needed.

Next, a procedure for setting a resource search environment performed by a business manager of program development will be described. The setting of the resource search environment is performed after the business manager has completed the creation of the directory corresponding to the business or after the completion.

First, the business manager of the program development notifies the system of the directory of the business whose resource search environment is to be set. Here, this directory is called a home position. Upon receiving the notification processing from the business administrator, the system performs processing to acquire resources for managing the resource search environment to be set. Specifically, a resource search environment that has already been saved under the home position directory, that is, when a saved search environment exists, processing is performed to incorporate the resource search environment to be set in the saved search environment from now on, On the other hand, if the saved search environment does not yet exist under the home position directory, processing is performed to secure resources for managing the new resource search environment on the storage medium.

Next, the business manager of the program development creates a resource search environment suitable for the program development of the business, and requests the system to set the created resource search environment. At this time, the business manager also specifies a search attribute indicating whether or not to set the resource search environment in consideration of the resources specified by the stored search environment of the routine work in the upper level of the tree structure. That is, one large routine task may be composed of a plurality of small routine tasks. Such a large fixed work corresponds to a higher directory as a higher fixed work, and a small fixed work corresponds to a lower directory as a lower fixed work. When a resource cannot be searched, it is possible to specify whether or not to use the storage search environment of a higher-level routine task. Upon receiving the setting request processing from the business manager, the system performs processing to set the search list, the resource name replacement information, and the search attribute requested to be set as a resource search environment.

Subsequently, the business manager of the program development requests that the set resource search environment be saved under the home position directory. When receiving the save request from the business manager, the system writes out the contents of the resource search environment set in the save search environment when the save search environment already exists under the home position directory. On the other hand, when the saved search environment does not exist under the home position directory, the contents of the resource search environment set for the newly secured resources are written out, and the written resources are registered as the saved search environment under the home position directory. Process.

FIG. 2 shows an example of a tree-structured directory that incorporates the saved search environment in this manner. 12, 1 in the figure
Reference numerals 3 and 14 denote a business directory (with a symbol), a storage and retrieval environment (with a symbol), and resource information (with a symbol) described with reference to FIG. As shown in this figure,
Each business directory 12 in the tree structure is configured to manage the resource search environment of the business unit requested to be set by the business manager of the program development as the saved search environment 13.

FIG. 3 shows an example of the stored search environment 13 loaded into a directory having a higher-order and a lower-order relationship. In the figure, “/” represents a hierarchical relationship, and the business directory 12-1 of “/ X” is the business directory 12 of “/ X / Y”.
-2 is in the upper directory, this "/ X / Y"
The business directory 12-2 of “/ X / Y / Z” is in a directory higher than the business directory 12-3 of “/ X / Y / Z”. From now on, the search attribute of the stored search environment 13-3 under the business directory 12-3 specifies the continuous search to be higher, and the search attribute of the stored search environment 13-2 under the business directory 12-2 is higher. Assuming that the continuous search is specified, the home position is
When it is assumed that the resource is set in the storage search environment 13-3, the resource search is executed in accordance with the storage search environment 13-2. If the resource cannot be searched, the resource is searched according to the stored search environment 13-1.

FIG. 4 shows a detailed embodiment configuration of the storage and retrieval environment 13 incorporated under the business directory 12. In this figure, a storage search environment 13 of a resource name “E1” is incorporated under the root business directory 12, and is located under the business directory 12 of a resource name “D1” located below the root directory 12. , An example in which the stored search environment 13 of the resource name “E2” is incorporated. Also, "D
The business directory 12 of "1" points to a file which is the resource information 14 with the resource name "F1" as the original resource management of the directory.

The “resource name” of each business directory 12 describes the name of a resource. The name of the saved search environment 13 to be incorporated needs to be fixed for each business directory 12. In addition, since the stored search environment 13 is managed in the same manner as other resources, the name of the stored search environment 13 must be a name that does not become the name of the business directory 12 or the name of the resource information 14. There is. "Resource attribute"
This is information for identifying whether the resource of the “resource name” to be pointed is the business directory 12, the storage and retrieval environment 13, the file, or the device. Originally, the stored search environment 13 does not enter here. However, in the present invention, the stored search environment 13 is treated as a resource on a storage medium, and the business related to the business of the stored search environment 13 is performed. Because you have registered in the directory 12, you will enter here. "Resource identification information"
Is composed of information for identifying the device in which the resource exists, and information for uniquely identifying the resource in the device. That is, the information points to the location of the resource of the “resource name”. “Search information” is, as described above, when a resource cannot be searched in the current stored search environment 13,
This is information indicating whether to continue searching for resources in the stored search environment 13 of the upper business directory 12.

"Replacement information" of the resource names that make up the saved search environment 13
Describes the content such as replacing "A" in the resource name with "B". By performing this replacement, the developer who develops the program can specify the resource by the resource name “B” which is easy to understand, instead of “A” that uniquely describes the location information of the resource. In the “search list”, the order of resource search is described.

Next, how to use such a stored search environment 13 registered by a program development business manager will be described.

A developer who executes a specific program development performs processing so as to notify the system of the business directory 12 of the routine business to be developed. Upon receiving this notification, the system sets the specified business directory 12
Is processed so as to specify and set the saved search environment 13 under the subdirectory as the resource search environment. That is, each developer can use the resource search environment registered by the business administrator of the program without having to set the resource search environment by himself. When the saved search environment 13 is set as the resource search environment in this way, the system
According to this resource search environment, a resource specifying process requested by the developer of the program development is executed.

For example, when the stored search environment 13 defines the search order of three files X, Y, and Z as “/ X / Y / Z” and “/ X / Y” according to the search list, When there is a read request for “A”, first, according to “/ X / Y / Z / A”, a search is made as to whether “A” is present next to “X → Y → Z”, If you can identify by this search "A" of the file
Can be read, and the process ends. On the other hand, if the file cannot be identified by this search, next, according to “/ X / Y / A”, the file is searched for “A” in the order next to “X → Y”, and the “A” of the file is searched. Reading will be performed.

If the file “A” cannot be specified in the stored search environment 13 and the search attribute specifies the resource search in the stored search environment 13 of the higher-level business directory 12, the stored search The resource search is executed according to the environment 13. For example, the saved search environment 13
Stipulates the substitution “A → B” for resource names,
When the search order is specified as “/ X”, replace “A” in the file with “B”, and then follow “/ X / B” in the order following “X”. By searching for “B”, the reading of “B” of the file is executed.

FIG. 5 schematically shows a procedure for resolving resource names when the business directory 12 has two levels. FIG. 5 (a) shows the configuration of the business directory 12 on which the description is based, and “C1” in the figure indicates the lower business directory 12.
Save search environment 13, "C2" is the upper business directory 12
Is the saved search environment 13. FIG. 5 (b) illustrates a procedure for resolving the resource name. "Case 1.1" and "Case 1.2" in FIG. 5 (b) are processing when the search attribute of the stored search environment 13 of "C1" does not specify a higher search, and "Case 1.1" or "Case 1.1""Case2.4" is a process in a case where there is no designation of a higher search. In the figure, "x" indicates that there is no designation of name replacement, and "o" indicates that there is designation of name replacement.

〔The invention's effect〕

As described above, according to the present invention, the resource search environment that can be standardized for each business unit of data processing is configured to be registered as a resource in the directory, so that the resource search environment can be disclosed and used freely. Developers and application programs who can directly use the resource search environment need not create and set up the resource search environment themselves.

In addition, since it is possible to specify the continuation of the search in the higher order in the stored search environment stored in the upper and lower relations, those using the resource search environment registered in the directory are unique to the system. It is not necessary to specify the resource name according to the identifier, and the description of the resource name can be executed according to the easy-to-understand logical name.
