Abstract

PURPOSE:To execute an operation maintenance highly economical with less labor by displaying the contents of a file to store title information to recognize the contents of stored information for each node and retrieving the other corresponding node when final information does not exist in a self-node. CONSTITUTION:In each node, the title information to recognize the contents of the information stored in a file 8 of the node is stored in a file 4, and the contents of the file 4 are displayed through a data retrieval program 5 on a retrieval terminal 6. When the fact that the final information does not exist in the node is decided from the display by a node classified information program 7, a node management table 9 is referred to by a network control program 10 through an operating system 13, and a final information transfer request to the node to store the final information is sent. Consequently, the final information with a large quantity of data has to be held only by a specific node, the economical character in the operation maintenance can be increased, and the labor reduction can be executed.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an information distributed processing system.

(Prior Art) Conventionally, in information distributed processing systems, database systems have been decentralized in each region for the purpose of distributing the load on database search systems.

However, in this case, since it is necessary for each system to hold and operate the same database information, there is a drawback that the operational cost for maintenance such as adding and deleting database information increases significantly.

(Problems to be Solved by the Invention) The present invention was made to solve such problems, and aims to provide an information distributed processing system that can reduce costs and labor in operation and maintenance. There is.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an information distribution processing system in which a plurality of nodes can mutually exchange information via a network, in which final information accumulated in each node is A display means for displaying a file in which title information whose contents can be understood is accumulated, a display means for displaying a list of title information accumulated in the file based on predetermined search conditions, and a display means for displaying a list of title information accumulated in the file based on predetermined search conditions; A determining means for determining whether the corresponding final information is in the own node or another node, and a command for forwarding the request command to the corresponding other node when the determining means determines that the final information is in the other node. The apparatus includes a transfer means, and an information return means that searches for and returns final information corresponding to the title information upon receiving a request command from the command transfer means.

(Function) In the present invention, the above means allows only a specific node to hold final information with a large amount of data, and each node only needs to hold only title information with a small amount of data, so that it is possible to add or delete database information. It is possible to reduce costs and labor in maintenance, that is, operational maintenance.

(Example) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a diagram showing the configuration of an information distributed processing system according to one embodiment of the present invention.

As shown in the figure, the information distributed processing system of this embodiment has a configuration in which a plurality of nodes 2 are connected to a common LAN bus 3.

FIG. 2 is a diagram showing the configuration of each node 2. As shown in FIG. In this system, as shown in FIG. 3, the structure of database information is divided into title information held in common by each node and final information held by a specific node.

In Fig. 2, 4 is a file in which title information (see Fig. 4) that allows you to know the content of the final information stored in each node is stored, and 5 is a file based on the search conditions input from the search terminal 6. 4 is a data search program that displays a list of accumulated title information on a search terminal 6; 7 is a data search program that displays a list of accumulated title information on a search terminal 6; This is a node-by-node information judgment program that judges whether it is in Nord.

Further, 8 is a file in which the final information is stored, 9 is a node management table in which node names corresponding to node numbers are stored, and 10 is a node-by-node information determination program 7 that determines that the final information is in another node. This is a network control program that transfers request commands sent at certain times to the corresponding nodes.

Furthermore, 11 is a network control program that receives request commands from the network control program 10;
is a node-by-node information determination program that searches the file 8 for final information corresponding to the title name upon receiving a request command from the network control program 11. Also,
When the final information is retrieved by the node-by-node information determination program 8, the network control program 11 returns this final information to the computer that issued the request command.

13 is an operation system (O8) that monitors and controls these processes.

Next, the operation of the system of this embodiment configured as described above will be explained based on the flowchart shown in FIG. 5 and the information flowchart shown in FIG.

When a predetermined search condition is input from the search terminal 6, a list of title information accumulated in the file 4 is displayed on the search terminal 6 by the data search program 5 based on the search condition (step a).

Next, when predetermined title information is input from the search terminal 6 based on the list of title information displayed on the search terminal 6 (step b), the final information corresponding to this title information is determined by the node-by-node information determination program 7. It is determined whether it is within the own node or in another node (step C).

If it is determined that the node exists in another node, the network control program 8 searches the node management table 91 for a node name corresponding to the node number, and transfers the request command to the corresponding node (step d).

When this request command is accepted by the network control program 11 in the corresponding node, this request command is sent to the node-by-node information determination program 12.

When the node-by-node information determination program 12 receives a request command from the network control program 11, the final information corresponding to the title name is searched from the file 8.

The final information retrieved is the network control program 1
1. The data is sent to the search terminal 6 via the network control program 8, the node-by-node information determination program 7, and the data search program 5.

Thus, in the system of this embodiment, in a decentralized information processing system, only a specific node has to hold the final information, which has a large amount of data, and each node has only to hold title information, which has a small amount of data. from,
Cost and labor can be reduced in maintenance such as addition and deletion of database information, that is, operational maintenance.

In particular, when the final information is image data or the like with a very large amount of information, the effect is tremendous.

Note that the present invention is not limited to the above-mentioned embodiments,
For example, it can be applied to message switching systems.

[Effects of the Invention] As explained above, according to the present invention, only a specific node has to hold the final information, which has a large amount of data, and each node has only to hold title information, which has a small amount of data. It is possible to reduce costs and labor in maintenance.
