Definitions
- the present invention relates to a configuration information management system for managing configuration information of each of distributed computers, more particularly to an effective technique preferred for a configuration information management system for setting up the configuration information divided and defined in each computer as its route information.
- a system configuration has a hierarchical structure consisting of branch offices, departments, etc.
- the manager has hierarchical layers in such a case.
- the manager of a lower-order hierarchical layer is referred to as a sub-manager.
- the configuration information of each computer under the sub-manager in a network is entered to the sub-manager manually or the sub-manager collects the configuration information through the above-described polling.
- the system configuration information entered or collected as described above is displayed as a system configuration map and used by the manager to execute remote commands to specified distributed computers on the map.
- the system configuration information is also used by each of the distributed computers to send events to its higher-order computer.
- the Japanese Patent Prepublication No.6-332779 discloses another method for managing the configuration information. According to the method, the whole configuration information is not set up in the manager. Each computer has only the configuration information of each of its lower-order computers.
- the configuration information is entered to the manager manually at a time.
- the supervisor of the manager computer in case the configuration of a branch office, a department, or the like in the system is modified, the supervisor of the manager computer must modify the configuration, so that the configuration modification of the whole system is concentrated on the manager computer. The load of the supervisor in the modification of the configuration information of the manager will thus be increased excessively. This has been a problem of the conventional method.
- the entire configuration information of the lower-order computers can be set up in each sub-manager.
- one department supervisor often manages a plurality of sub-managers, so that the supervisor must set up the configuration information at each sub-manager computer.
- the supervisor's labor has thus become a problem.
- the supervisor can also modify the configuration information by remote operation. Still in this case, because the manager must set up the configuration information for each sub-manager, it has arisen another problem that the remote operation takes much time and labor from the supervisor of the manager computer.
- the method for collecting information from lower-order computers in a network by polling can save the manual data input labor, but it can apply only to the collection of such physical network configuration information as the IP address and the MAC address set in each computer.
- the method is not suitable for setting up the configuration information of a system when logical configuration of the system must be managed for each use purpose of computers. This is because computers whose use purposes are different from each another, for example, distribution management computers, application execution computers, etc., are often installed together in a physical network.
- the logical configuration of a system is often formed over a plurality of networks, so the logical configuration information must be set up separately from the physical configuration information.
- the physical configuration mentioned here means information denoting how computers are actually arranged in a network as shown in FIG. 11 .
- Information of respective computers is, as described above, the IP address, the MAC address, etc. set up in each computer.
- the logical configuration is defined by a human being and it means information denoting the relationship among computers.
- a supervisor defines a computer 1 shown in FIG. 11 as a “manager”, a computer 2 shown in FIG. 11 as a “client 1”, a computer 3 shown in FIG. 11 as a “sub-manager 1”, a computer 4 shown in FIG. 11 as a “sub-manager 2”, and a computer 5 shown in FIG. 11 as a “client 2” respectively.
- FIG. 12 (upper figure) shows an image of the assignment.
- a logical configuration (a hierarchical structure of computers) defines those computers by use purpose so as to represent those computers as a tree structure according to each use purpose of the computers separately from the actual physical arrangement of them.
- FIG. 12 shows this logical configuration.
- “manager”, “client”, etc. are used to describe the definition of each use purpose of computers, but they may be replaced with other words, of course.
- the Japanese Patent Prepublication No. 6-332779 discloses a method for managing hierarchical information of computers.
- the gazette does not describe any method for setting up the hierarchical information, however.
- the configuration information management system for managing configuration information of each of distributed computers enables configuration information to be set up in a specific range, then the set-up configuration information to be reflected throughout the entire configuration information of the system.
- the configuration information management system of the present invention in case the system configuration information is modified due to addition of a computer, etc. the configuration information denoting the configuration in the specific range including the modified portion is entered to the system, then the modified configuration information is sent to all the computers in the range denoted by the configuration information, thereby the configuration information is set up in each of the computers in the subject range.
- the configuration information management system of the present invention also requests each of the distributed computers to send its configuration information set up in the computer after setting up the configuration information denoting the configuration in a specific range as described above. Receiving the request, each computer reads the configuration information set up in itself and sends it to other computers sequentially, then receives the configuration information of each of those other computers, thereby updating the configuration information in itself.
- the supervisor who is not required to know the entire configuration of all the distributed computers when modifying the configuration of a computer, can modify the configuration information of the whole system by giving the configuration information divided into that in a specific range to all the distributed computers.
- One of the divided hierarchical information layers in specific ranges may include a plurality of department sub-managers.
- configuration information may be sent and set up with a command from a computer that is not included in the system configuration information and the supervisor can modify the configuration information from any place regardless of the manager-installed place.
- a computer that is not included in the logical configuration of a system can send and set up its configuration information if it can access a manager computer.
- the present invention because hierarchical information is divided into those in specific ranges and given to other computers, the logical configuration information of a system over one or a plurality of sub-managers can be managed easily. Because the hierarchical information held in each of distributed computers is minimized, the storage capacity of the information can be minimized. The number of computers whose configuration information must be updated due to partial modification of the system configuration information becomes less. Especially, this method is effective when a system is composed of many distributed computers.
- configuration information after it is set up in a specific range, is reflected throughout the configuration information of the whole system, so the logical configuration information of a system can be divided into those in specific ranges and given to other computers in each specific range, thereby making it easier to manage the logical configuration information of each of those distributed computers.

- Computers hierarchical information layer 120 denotes a hierarchical configuration of the entire system.
- Computer hierarchical information layers 100 and 110 are divided computer hierarchical information layers.
- the computer hierarchical information layer 110 of a branch office is added to the computer hierarchical information layer 100 of the head office.
- the supervisor enters the computer hierarchical information layer 110 denoting the configuration in the range newly so as to execute a distribution command, thereby directing the distribution of the hierarchical information.
- the new hierarchical information is set up in the computers in the range, beginning at the highest-order computer 12 .
- the new hierarchical information is thus set up in all the computers in the range.
- the supervisor executes a synchronized command so as to direct a synchronization processing for reflecting the hierarchical information set in each computer throughout the entire system.
- the hierarchical information is sent to the lower-order computers in ascending order, beginning at the lowest-order computers 1111 and 1112 , 1121 and 1122 , as well as 1221 and 1222 under the control of the highest-order computer I.
- the hierarchical information divided into the computer hierarchical information layers 100 and 110 are thus integrated into the computer hierarchical information layer 120 .
- the computers 1111 and 1112 send their hierarchical information to the computer 111 , which is their upper-order computer.
- the computers 1121 and 1122 , as well as the computers 1221 and 1222 send their hierarchical information to their upper-order computers respectively.
- the computer 111 integrates information pieces received from the computers 1111 and 1112 so as to create a lower-order computers hierarchical information layer, thereby updating the lower-order computers hierarchical information held in itself.
- the computer 111 then sends the created lower-order computers hierarchical information to its upper-order computer 11 .
- the computer 11 then sends the hierarchical information of its lower-order computers to its upper-order computer 1 .
- the hierarchical information of the lower-order computers is created by integrating the hierarchical information received from the computer 111 and the hierarchical information received from the computer 112 .
- the computer 1 (the highest-order computer of the hierarchical structure of the above computers) integrates the hierarchical information of the lower-order computers of the computer 11 received from the computer 11 and the hierarchical information of the lower-order computers of the computer 12 received from the computer 12 so as to form the hierarchical information 120 of all the computers in the system.
- Hierarchical information is thus sent from lower-order computers to upper-order computers sequentially in response to each of executed synchronized commands (synchronization processing) as described above, thereby the hierarchical information held in each of those computers is updated. Therefore, the supervisor is not always required to know the hierarchical structure of the respective computers in the system.

The above method, which manages configuration information of each of distributed computers, comprises a step of setting up configuration information in a specific range in a computer in the specific range; a step of requesting acquisition of configuration information set up in another computer; a step of sending configuration information set up in a subject computer to above-described another computer; and a step of updating configuration information of the subject computer with configuration information received from above-described another computer.
Description
- This application is a continuation of U.S. application No. 09/696,129, filed Oct., 24, 2000, which in turn claims priority from Japanese Application No. 2000-066548, filed Mar. 10, 2000.
- The present invention relates to a configuration information management system for managing configuration information of each of distributed computers, more particularly to an effective technique preferred for a configuration information management system for setting up the configuration information divided and defined in each computer as its route information.
- There is a conventional method for managing configuration information of each of distributed computers collectively by setting up the whole configuration of those distributed computers in one computer referred to as a manager. In this case, the configuration information of each computer is entered to the manager manually or the manager attempts to communicate with each of those distributed computers so as to collect the configuration information of each lower-order computer in a network according to the returned IP address (hereinafter, the processing will be referred to as polling).
- There is also another conventional method employed when a system configuration has a hierarchical structure consisting of branch offices, departments, etc. The manager has hierarchical layers in such a case. In this case, the manager of a lower-order hierarchical layer is referred to as a sub-manager. When managing such a lower-order hierarchical information, the configuration information of each computer under the sub-manager in a network is entered to the sub-manager manually or the sub-manager collects the configuration information through the above-described polling.
- The system configuration information entered or collected as described above is displayed as a system configuration map and used by the manager to execute remote commands to specified distributed computers on the map. The system configuration information is also used by each of the distributed computers to send events to its higher-order computer.
- The Japanese Patent Prepublication No.6-332779 discloses another method for managing the configuration information. According to the method, the whole configuration information is not set up in the manager. Each computer has only the configuration information of each of its lower-order computers.
- Conventionally, to set up the whole configuration information of distributed computers, the configuration information is entered to the manager manually at a time. In this case, in case the configuration of a branch office, a department, or the like in the system is modified, the supervisor of the manager computer must modify the configuration, so that the configuration modification of the whole system is concentrated on the manager computer. The load of the supervisor in the modification of the configuration information of the manager will thus be increased excessively. This has been a problem of the conventional method.
- In this case, the entire configuration information of the lower-order computers can be set up in each sub-manager. In a large department, however, one department supervisor often manages a plurality of sub-managers, so that the supervisor must set up the configuration information at each sub-manager computer. The supervisor's labor has thus become a problem. In this case, the supervisor can also modify the configuration information by remote operation. Still in this case, because the manager must set up the configuration information for each sub-manager, it has arisen another problem that the remote operation takes much time and labor from the supervisor of the manager computer.
- The method for collecting information from lower-order computers in a network by polling can save the manual data input labor, but it can apply only to the collection of such physical network configuration information as the IP address and the MAC address set in each computer. In actual usage of the configuration information, the method is not suitable for setting up the configuration information of a system when logical configuration of the system must be managed for each use purpose of computers. This is because computers whose use purposes are different from each another, for example, distribution management computers, application execution computers, etc., are often installed together in a physical network. Generally, the logical configuration of a system is often formed over a plurality of networks, so the logical configuration information must be set up separately from the physical configuration information.
- The physical configuration mentioned here means information denoting how computers are actually arranged in a network as shown in
FIG. 11 . Information of respective computers is, as described above, the IP address, the MAC address, etc. set up in each computer. - Unlike the physical configuration, the logical configuration is defined by a human being and it means information denoting the relationship among computers. For example, a supervisor defines a
computer 1 shown inFIG. 11 as a “manager”, acomputer 2 shown inFIG. 11 as a “client 1”, acomputer 3 shown inFIG. 11 as a “sub-manager 1”, acomputer 4 shown inFIG. 11 as a “sub-manager 2”, and acomputer 5 shown inFIG. 11 as a “client 2” respectively.FIG. 12 (upper figure) shows an image of the assignment. A logical configuration (a hierarchical structure of computers) defines those computers by use purpose so as to represent those computers as a tree structure according to each use purpose of the computers separately from the actual physical arrangement of them.FIG. 12 (lower figure) shows this logical configuration. In the above case, “manager”, “client”, etc. are used to describe the definition of each use purpose of computers, but they may be replaced with other words, of course. - The Japanese Patent Prepublication No. 6-332779 discloses a method for managing hierarchical information of computers. The gazette does not describe any method for setting up the hierarchical information, however.
- Under such circumstances, it is an object of the present invention to provide a technique that can solve the above conventional problems and divide logical configuration information of computers into configuration information in specific ranges, thereby making it easier to manage the logical configuration information of each of distributed computers.
- In order to achieve the above object, the configuration information management system for managing configuration information of each of distributed computers according to the present invention enables configuration information to be set up in a specific range, then the set-up configuration information to be reflected throughout the entire configuration information of the system.
- In the configuration information management system of the present invention, in case the system configuration information is modified due to addition of a computer, etc. the configuration information denoting the configuration in the specific range including the modified portion is entered to the system, then the modified configuration information is sent to all the computers in the range denoted by the configuration information, thereby the configuration information is set up in each of the computers in the subject range.
- The configuration information management system of the present invention also requests each of the distributed computers to send its configuration information set up in the computer after setting up the configuration information denoting the configuration in a specific range as described above. Receiving the request, each computer reads the configuration information set up in itself and sends it to other computers sequentially, then receives the configuration information of each of those other computers, thereby updating the configuration information in itself.
- As described above, because the present invention enables the configuration information in a specific range to be set up, then the configuration of each computer to be set up in other computers so that the configuration information set up in the specific range is reflected throughout the configuration information of the whole system, the supervisor, who is not required to know the entire configuration of all the distributed computers when modifying the configuration of a computer, can modify the configuration information of the whole system by giving the configuration information divided into that in a specific range to all the distributed computers. One of the divided hierarchical information layers in specific ranges may include a plurality of department sub-managers.
- Furthermore, according to the present invention, configuration information may be sent and set up with a command from a computer that is not included in the system configuration information and the supervisor can modify the configuration information from any place regardless of the manager-installed place.
- Concretely, even a computer that is not included in the logical configuration of a system can send and set up its configuration information if it can access a manager computer.
- As described above, according to the present invention, because hierarchical information is divided into those in specific ranges and given to other computers, the logical configuration information of a system over one or a plurality of sub-managers can be managed easily. Because the hierarchical information held in each of distributed computers is minimized, the storage capacity of the information can be minimized. The number of computers whose configuration information must be updated due to partial modification of the system configuration information becomes less. Especially, this method is effective when a system is composed of many distributed computers.
- As described above, according to the configuration information management system of the present invention, configuration information, after it is set up in a specific range, is reflected throughout the configuration information of the whole system, so the logical configuration information of a system can be divided into those in specific ranges and given to other computers in each specific range, thereby making it easier to manage the logical configuration information of each of those distributed computers.

hierarchical information layer 120 denotes a hierarchical configuration of the entire system. Computer hierarchical information layers 100 and 110 are divided computer hierarchical information layers. InFIG. 1 , the computerhierarchical information layer 110 of a branch office is added to the computerhierarchical information layer 100 of the head office. - As shown in
FIG. 1 , in case the configuration is modified in such a specific range of a branch office or the like denoted by the computerhierarchical information 110, the supervisor enters the computerhierarchical information layer 110 denoting the configuration in the range newly so as to execute a distribution command, thereby directing the distribution of the hierarchical information. Receiving the distribution command for the hierarchical information, the new hierarchical information is set up in the computers in the range, beginning at the highest-order computer 12. The new hierarchical information is thus set up in all the computers in the range. - As described above, after the configuration information denoting such a specific range as a branch office having distributed computers is set up in the computers in the range, the supervisor executes a synchronized command so as to direct a synchronization processing for reflecting the hierarchical information set in each computer throughout the entire system. Receiving the command for synchronizing the hierarchical information, the hierarchical information is sent to the lower-order computers in ascending order, beginning at the lowest-
order computers hierarchical information layer 120. - Concretely, the
computers computer 111, which is their upper-order computer. In the same way, thecomputers computers - The
computer 111 integrates information pieces received from thecomputers computer 111 then sends the created lower-order computers hierarchical information to its upper-order computer 11. - The
computer 11 then sends the hierarchical information of its lower-order computers to its upper-order computer 1. The hierarchical information of the lower-order computers is created by integrating the hierarchical information received from thecomputer 111 and the hierarchical information received from thecomputer 112. Finally, the computer 1 (the highest-order computer of the hierarchical structure of the above computers) integrates the hierarchical information of the lower-order computers of thecomputer 11 received from thecomputer 11 and the hierarchical information of the lower-order computers of thecomputer 12 received from thecomputer 12 so as to form thehierarchical information 120 of all the computers in the system. - Hierarchical information is thus sent from lower-order computers to upper-order computers sequentially in response to each of executed synchronized commands (synchronization processing) as described above, thereby the hierarchical information held in each of those computers is updated. Therefore, the supervisor is not always required to know the hierarchical structure of the respective computers in the system.

Theprocessor 213 then sets up the lower-order computershierarchical information 312 of thecomputer 111 created instep 907 in the lower-order computershierarchical information 208 of thecomputer 111 instep 908. - In

Theprocessor 214 then analyzes theinformation 207 instep 911 and sends the communication data (5) to thecomputer 11 specified by the upper-computers information 207 instep 912. - Just like the
computer 111, the configurationinformation acquisition processor 213 of thecomputer 11 sets up the createdinformation 312 in the lower-order computershierarchical information 208 of thecomputer 11. The configurationinformation sending processor 214 of thecomputer 11 sends the recreated communication data (5) to thecomputer 1 specified by the upper-computer information 207 of thecomputer 11. - Hereinafter, data is set/sent in/to the lower-order computers

step 904, the configurationinformation acquisition processor 213 of thecomputer 1 waits for the communication data (5) to be received from thecomputers computer 1. When theprocessor 213 receives the communication data (5), control goes to step 905. Theprocessor 213 then creates the computershierarchical information 315 of thecomputers computer 1 from the lower-computershierarchical information 452 of the received communication data (5) and the information of the source computer that has sent the communication data (5). - In
step 906, in case theprocessor 213 receives the communication data (5) from all the computers positioned just under thecomputer 1, control goes to step 907. Otherwise, control goes to step 904. - In

Theprocessor 213 then sets up theinformation 312 created instep 907 in the lower-order computershierarchical information layer 208 of thecomputer 1 instep 908. - In
step 909, the configurationinformation sending processor 214 of thecomputer 1 checks if thecomputer 1 has the upper-order computer information 207. Because thecomputer 1 does not have theinformation 207 at this time, the processor exits the processing. - As described above, in this embodiment, after the computers configuration information in such a specific range as a computer network, etc. in a branch office is set up, a synchronized command is executed in the manager so as to send the lower-order computers configuration information to the upper-order computer. Consequently, the computers configuration information set up in the specific range can be reflected throughout the configuration information of the whole system. It is thus possible to modify the configuration information of the whole system with the configuration information of each of lower-order computers separated in a specific range; the supervisor is not required to know the whole configuration information of a distributed computer system when modifying the configuration information of any of the distributed computers in a specific range respectively.
- Furthermore, in this embodiment, setting up of the configuration information in a specific range is started at the highest-order computer in the range, so that the processing becomes the same as that of the processing system of distributed computers in which a processing is executed in response to a remote command issued from an upper-order computer to lower-order computers. It is thus possible to set up the configuration information in accordance with an existing processing system.
- Furthermore, in this embodiment, the configuration information of a distributed computer is represented by both of the upper-
order computer information 207 denoting the upper-order computer connected to the subject computer and the lower-order computershierarchical information 208 denoting the hierarchical information of the lower-order computers connected to the subject computer. Updating of the configuration information of the subject computer is started at the lowest-order computer to the highest-order computer in a system so as to synchronize the lower-order computershierarchical information 208 among all the computers in the system by receiving the configuration information set up in other computers. It is thus possible to assume the synchronization of theinformation 208 without any of duplication of the synchronization processing and disagreement in hierarchical information among those computers. - As described above, according to the configuration information management system in this embodiment, the configuration information in a specific range is set up, then the set-up information is reflected throughout the configuration information of the whole system. It is thus possible to divide the logical configuration information of the system and give the divided configuration information to computers in a specific range respectively so as to make it easier to manage the logical information of each distributed computer.
- The logical configuration information of a computer denotes configuration information (as shown in the lower part of
FIG. 12 ) corresponded by the supervisor to a subject computer according to its use purpose. The logical configuration information differs from the information denoting the physical connection state of the computer (FIG. 11 ). In this specification, logical configuration information is managed as an embodiment of the present invention. However, other information may also be managed by the configuration information management method as described above in the present invention. - According to the present invention, therefore, because the configuration information in a specific range is reflected throughout the configuration of the subject whole system after it is set up in the range, the logical configuration information can be divided into those in specific ranges and the configuration information in a specific range can be given to computers in the specific range. Thus, this method makes it easier to manage the logical configuration information of each of those distributed computers.
- Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been changed in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
- The preceding has been a description of the preferred embodiment of the invention. It will be appreciated that deviations and modifications can be made without departing from the scope of the invention, which is defined by the appended claims.
