[Industrial applications]

The present invention relates to an information inquiry processing method, in particular, communication in which at least a plurality of management systems are linked via a communication network and one management system makes an inquiry about a managed system belonging to another management system to another management system. The present invention relates to an information inquiry processing method in which another management system having a high success rate as a result of inquiries in the past is retained in a dynamic priority list.

As information processing systems become more sophisticated, multiple management systems that exist in a distributed manner hold individual information, and each management system uses the individual information while making inquiries as necessary. The method of doing is adopted. It is desired to improve the inquiry efficiency in this case.

[Conventional technology]

Communication in which one or a plurality of managed systems belong to the management range of a single management system, and a plurality of managed systems are linked together with the managed system or excluding the managed system (1). Network (3)
There is known a communication system having.

In such a communication system, when one management system wants to obtain information about a managed system belonging to another management system, the following method has been considered. That is, (A) for all managed systems, the correspondence with the management system is defined and held in each management system, and a predetermined management system is inquired based on the information, (B) the above information It was considered that all management systems should be inquired at once without having the above, and (C) management systems should be inquired in order without having the above information.

[Problems to be solved by the invention]

In the case of the above method (A), it is burdensome to hold the above information in each management system, and it is difficult to deal with a change in correspondence. The above methods (B) and (C)
In the case of, inquiries are inefficient.

It is an object of the present invention to provide a system that holds a smaller amount of information and that has an efficient inquiry.

[Means for solving problems]

FIG. 1 shows the principle configuration of the present invention. Symbols 1a, 1 in the figure
b, ..., 1z are managed systems, 2A, 2B, ..., 2G are managed systems, 3 is a communication network, 4 is another management system information holding unit, 5 is a managed system information holding unit, and 6 is a transmission / reception process. Mechanism, 7 is a dynamic priority list, 8 is an update mechanism, 9 is an information retrieval mechanism, 10 is an inquiry request source, 11 is an inquiry acceptance unit, 12 is an inquiry response unit, 13 is a transmission mechanism unit, and 14 is It represents the receiving mechanism.

The other management system information holding unit 4 includes the other management systems 2B, 2
Holds information about C, ..., 2G. The managed system information holding unit 5 stores the managed system belonging to itself, for example,
It holds information about 1a, 1b, 1c, 1d.

The dynamic priority list 7 succeeded in the inquiry about the other management system (the inquiry about the information regarding the managed systems 1e, 1f, ... 1z belonging to the other management systems 2B, 2C ...) The rate is held as information for each other management system or for each group of other management systems in which a plurality of them are collected. The updating mechanism 8 updates the contents of the dynamic priority list 7 in accordance with the results of the above inquiries.

[Action]

It is assumed that the inquiry request source 10 in the management system 2A makes an inquiry about a certain managed system 1j.
The inquiry is set in the inquiry reception unit 11 and guided to the information retrieval mechanism 9. Whether or not the managed system 1j, which is the inquiry target, belongs to itself can be known from the contents of the managed system information holding unit 5.

If it belongs to another management system (which management system is undetermined), the contents of the dynamic priority list 7 are checked. If the inquiry to the management system 2B had a high success rate in the past inquiry (as can be seen from the contents of list 7), the information retrieval mechanism 9 relates to the management system 2B from the contents of the other management system information holding unit 4. The address etc. are extracted, and via the transmission mechanism unit 13,
The inquiry is transferred to the management system 2B on the communication network 3.

In the management system 2B, referring to the drawing of the illustrated system 2A, the inquiry reception unit 11 receives the information via the reception mechanism unit 14. Then, the information retrieval mechanism 9 checks the contents of the managed system information holding unit 5. If it does not belong to itself, the inquiry response unit 12 sets that fact, and the management system 2A is answered “No” via the transmission mechanism unit 13.

When the management system 2A accepts the "no", the information retrieval mechanism 9 extracts the management system or management system group having the next highest priority from the dynamic priority list 7 and makes an inquiry. When making inquiries to a group, do it all at once. Assuming that the managed system 1j belongs to the management system 2C, the information desired by the management system 2C is returned. This reply is notified from the reception mechanism unit 14 to the inquiry request source 10 through the information retrieval mechanism 9 and the inquiry response unit 12. In response to these results,
The update mechanism 8 updates the contents of the dynamic priority list 7.
That is, for example, the success count information regarding the management system 2C is incremented by one.

〔Example〕

FIG. 2 shows an example in which the management system manages the managed system, and FIG. 3 shows a configuration example of the dynamic priority list. FIG. 4 shows an example of the update result of the dynamic priority list.

In FIG. 2, 1a, 1b, ..., 1z are managed systems, 2 respectively.
A, 2B, ... Represent a management system, respectively. In the illustrated case, for example, the management system 2C is the managed system 1i, 1
It manages j, 1k and 1l.

In FIG. 3, 7 indicates a dynamic priority list.
At this time, the one with the highest priority is set as group 1, the management system for the second and third positions is group 2, and the management system for the fourth to sixth positions is group 3. In the case shown in the figure, the past success rate for the management system 2B is "100" at maximum.

In the case shown in FIG. 3, (1) When making an inquiry about the managed system 1e, make an inquiry to the management system 2B from the contents of list 7, and make an inquiry from the setting example shown in FIG. Is successful, and the value “100” is set to the value “101” on the list 7.

(2) When making an inquiry about the managed system 1j, an inquiry is made to the management system 2B from the contents of the list 7 and fails, and then an inquiry is made to the management systems 2G and 2C. ， Successful in management system 2C.
From this, the value “60” is the value “61” on the list 7.
Will be updated to

(3) When inquiring about the managed system 1q, based on the contents of the list 7, an inquiry is made to the management system 2B and fails, then an inquiry is made to the management systems 2G and 2C, and the operation fails. Next, the management systems 2F, 2D, and 2E are queried, and the management system 2E succeeds, and the value "10" is updated to the value "11" on the list 7.

FIG. 4 shows a state in which the management system 2G has been successfully inquired 11 times from the state shown in FIG.
In this case, the management system located in group 1 has been switched from system 2B to system 2G.

In the above description, if the inquiry succeeds, the value is increased by 1 on the list 7 and the value for the other management system is not touched. However, the values of other management systems may be decreased by one. Further, in the present invention, the managed systems 1a, 1b, ... Are described as constituting one data processing device, but the present invention is not limited to this. It may be the information itself.

〔The invention's effect〕
