Abstract

Processing machines which perform operational processing, data machines which perform data access and/or man-machine interface machines which perform man-machine interface processing, are in a configuration in which they are connected to a network. A first network manager which is connected to the network manages the connection attributes among said machines and the connection relationships among said machines by mutual sending and receiving of electronic statements. A second network manager manages the connection relationships of said machines in a plurality of local networks which comprise a single large network.

Claims

1. An automatic creation system for device connection definitions in a data independent type computer system connected to a network, said automatic creation system comprising:

a processing machine which receives from the network first electronic statements containing operational processing requests from the network, sends second electronic statements containing results of operational processing to the network, sends third electronic statements containing data access requests to the network, receives fourth electronic statements containing results of data access from the network, and executes the operational processing corresponding to the first through fourth electronic statements;

a data machine which receives the third electronic statements containing the data access requests from the network, sends the fourth electronic statements containing the results of the data access requests to the network, and accesses stored data in response to the third electronic statements;

a man-machine interface machine which sends the first electronic statements containing the operational processing requests to the network, receives the second electronic statements containing the results of the operational processing from the network, and executes man-machine-interface processing corresponding to the first and second electronic statements;

means for connecting at least one of said processing machine, said data machine and said man-machine interface machine to the network; and

a first network manager, connected to the network, which manages the connection attributes and the connection relationships among any of said processing machine, said data machine and said man-machine interface machine connected to the network.

2. An automatic creation system for device connection definitions as described in claim 1,

wherein said first network manager, at the time at which at least one of said processing machine, said data machine and said man-machine interface machine is connected to the network, acquires the connection attributes of the at least one of said processing machine, said data machine and said man-machine interface machine by receiving a fifth electronic statement containing the connection attributes from each of said processing, data and man-machine interface machines to each other of said processing, data and man-machine interface machines;

receives changes in the connection relationships among said processing machine, said data machine and said man-machine interface machine on the network; and

, at a time when a change in the connection relationships occurs, sends a sixth electronic statement containing information relating to the change in the connection relationships, to each of said processing machine, said data machine and said man-machine interface machine that is involved in the change; and

wherein each of said processing machine, said data machine and said man-machine interface machine, upon receiving the electronic statement, changes the connection status thereof based on the information relating to the change in the connection relationships contained in the sixth electronic statement.

3. An automatic creation system to create device connection definitions as described in claim 1, wherein said first network manager manages the connection attributes or the connection relationships together, which are common among any of said processing machine, said data machine and said man-machine interface machine.

4. An automatic creation system to create device connection definitions as described in claim 3, wherein said first network manager hierarchically incorporates and manages further common connection attributes or connection relationships which are managed together in said first network manager.

5. An automatic creation system to create device connection definitions as described in claim 1, wherein the network consists of a plurality of local networks,

wherein said first network manager is connected to a first local network and manages the connection attributes when at least one of said processing machine, said data machine and said man-machine interface machine is connected to the first local network, and manages the connection relationships among said processing machine, said data machine and said man-machine interface machine on the first local network;

and

wherein said automatic creation system further comprises a second network manager connected to a second local network, to manage the connection attributes when at least one of said processing machine, said data machine and said man/machine interface machine is connected to the second local network, and to manage the connection relationships among said processing machine, said data machine and said man-machine interface machine on the second local network.

6. An automatic system to create device connection definitions as described in claim 5,

wherein at a time at which there is a change in management status of at least one of the connection attributes and the connection relationships in said first network manager, said second network manager changes the management status therein by receiving a fifth electronic statement containing first information relating to the change in the management status of the at least one of the connection attributes and the connection relationships, from said first network manager, receives the change in the connection relationships among said processing machine, said data machine and said man-machine interface machine in the plurality of said local networks;

and sends a sixth electronic statement containing second information relating to the change to said first network manager; and

wherein said first network manager upon receiving the sixth electronic statement changes the management status therein based on the information relating to the change in the connection relationships in the sixth electronic statement.

7. An automatic system to create device connection definitions as described in claim 5, wherein at least one of said first and second network managers manages any of the connection attributes and the connection relationships together, which are common among said processing machine, said data machine and said man-machine interface machine.

8. An automatic system to create device connection definitions as described in claim 5, wherein at least one of said first and second network managers hierarchically incorporates and manages further common connection attributes or connection relationships which are managed together in said first network manager.
