Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for realizing an operation command in a distributed system, and more particularly, a plurality of information processing devices and one operation terminal, and these information processing devices and the operation terminal are mutually connected. In a distributed system consisting of a network, if there are common information and individual information for each information processing device and an operation command to refer to or update them is provided, there are multiple operators who use the operation terminal. The present invention relates to a method and an apparatus for realizing an operation command in a distributed system so that the information processing apparatus can be operated without being aware of the configuration content of the information processing apparatus.

[0002]

2. Description of the Related Art FIG. 12 shows the configuration of a conventional distributed system. The distributed system shown in the figure includes an operation terminal 10, a network 20, and a plurality of information processing devices 30. The operation terminal 10 includes an operation application program 11, a holding unit 12, and a communication unit 13. The network 20 is a network such as FDDI that connects the operation terminal 10 and the information processing device 30 to each other.

The holding unit 12 manages which information processing device each information is stored by using a storage unit such as a database. The communication unit 13 transmits an operation command or receives a result response. The operation application program 11 searches the information processing apparatuses 30 ₁ to 30 _n holding the required information from the holding unit 12 at the time of issuing the command, and performs control to send the operation command to each of the searched information processing apparatuses.

The holding unit 12 may be present not only in the operation terminal 10 but also in a specific information processing device (eg, 30 ₁ ). When transmitting an operation command from the operation terminal 10 to the plurality of information processing devices 30 in the above configuration, the holding unit 12 is searched and the information to be acquired is held before the operation command is transmitted from the communication unit 13. The destination address information of the information processing device is acquired. Here, when the information to be acquired exists in a plurality of information processing devices 30,
The operation terminal 10 issues an operation command to the plurality of information processing devices 30.

[0005]

However, the above-mentioned conventional distributed system has the following problems. (1) The conventional information holding method of the holding unit must always match the held information of each information processing apparatus itself, but the configuration of the information processing apparatus was changed and the information processing apparatus was locally maintained. In this case, it is necessary to update the information held in the information holder, and a mistake in the operation to update the information held in the information holder may cause a mismatch with the information processing device, which may cause the system to not operate properly. is there.

(2) Further, when the information processing device cannot return the result response due to a failure or the like, the response time becomes a response time-out time, and there is a problem in responsiveness. The present invention has been made in view of the above points, and enables reduction of management information, reduction of SG man-hours and SG mistakes in the case of system configuration change, application program accommodation replacement, and the like, and an information processing apparatus. It is an object of the present invention to provide a method and a device for realizing an operation command in a distributed system, which can shorten the response time due to the above-mentioned failure and improve the responsiveness.

[0007]

According to the present invention, there is provided a method for realizing an operation command in a distributed system including a plurality of information processing apparatuses, one operation terminal, and a network connecting these operation terminals to each other. Operate commands that refer to or update common information and individual information,
The information is transferred from the operation terminal to all the information processing apparatuses, and the response from the information processing apparatus is edited and output as a command result of a single information processing apparatus system in the operation terminal.

Further, according to the present invention, it is assumed that the operation terminal holds the state of each information processing apparatus and does not transmit the operation command to the information processing apparatus in the abnormal state. FIG. 1 is a diagram for explaining the principle of the present invention. The present invention transfers the operation command to all normal information processing devices (step 1),
The responses from all normal information processing devices are collected (step 2), and among the responses corresponding to the operation command,
The same response is aggregated into one response, and different responses are displayed as they are (step 3).

FIG. 2 is a diagram showing the principle of the present invention. The present invention relates to a distributed system including a plurality of information processing apparatuses, one operation terminal, and a network connecting these operation terminals to each other.
Status information holding means 102 for holding the status information of the above, and transfer means 103 for referring to the status information of the status information holding means 102 to transfer the operation command to the information processing device 300.
Receiving means 105 for receiving responses from all information processing devices
And a receiving unit 105, and an editing unit 106 that edits the received response message to display it like a response message from a single information processing apparatus.

The transfer means 103 transfers the operation command only to the information processing apparatus 300 whose status information held by the status information holding means 102 is normal. From the response received by the receiving unit 105, the editing unit 106 obtains the response of the information processing apparatus whose state is normal in the state information holding unit 102, and the response obtained by the response obtaining unit. It includes a response selecting unit that selects a significant response corresponding to the operation command, and an aggregating unit that aggregates the same response among the responses corresponding to the operation command acquired by the response selecting unit.

The present invention further includes state information updating means for updating the contents of the state information holding means 102 when the state of the information processing device 300 changes. As a result, according to the present invention, the transfer means 103 and the status information holding means 102 transfer the operation command to all the information processing apparatuses 300 that are operating normally, and the receiving means 105 causes the information processing apparatus 3 to operate.
When the response is received from 00, only the responses from the information processing device 300 that is normally operating are collected by referring to the state information holding unit 102 and passed to the editing unit 106. Editing means 1
06 deletes the response that does not correspond to the transmitted operation command from the responses from the information processing device, and acquires only the corresponding response. Further, the editing unit 106 aggregates the same response into one message from the acquired responses, and displays different responses as they are, so that the same display as the response from the single information processing device is displayed. Since it takes the form, the operator does not need to be aware of a plurality of information processing devices from issuing the operation command to viewing the response display.

Further, in the status information holding means 102,
Since the status information of all the information processing devices 300 is centrally managed, the transfer means 103 and the receiving means 105 cannot be applied with the operation commands as they are due to a system change of the information processing devices, or the operation is stopped due to a failure. It is possible to grasp the status information of the information processing device. Therefore, with respect to the information processing device in the abnormal state, it is possible to perform processing such as not transmitting the operation command or displaying the state information of the information processing device in the abnormal state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows the configuration of the distributed system of the present invention. The distributed system shown in FIG.
0, a plurality of information processing devices 300 _{1 to} 300 _n , an operation terminal 100, and a network 200 connecting the respective information processing devices 300 to each other.

The operation terminal 100 includes an operation application program 101, a destination list 102, and a delivery section 10.
3, reception list 104, reception unit 105, editing unit 106,
It is composed of an output buffer 107 and a display unit 108.
The operation application program 101 has an operation command, transfers the operation command to the delivery unit 103, and operates the system.

Destination list 102 and reception list 104
Is all information processing devices 3 connected to the operation terminal 100.
00, status information (normal / abnormal), destination address information, and the like. When the delivery unit 103 acquires the operation command from the operation application program 101, the delivery unit 103 refers to the destination list 102 to acquire all information processing device IDs and destination addresses in a normal state, and corresponds to the information processing device ID. Information processing device 30
The acquired command is transmitted to 0.

The receiving unit 105 refers to the reception list 104, transfers the normally received response among the response messages received from all the information processing devices to the editing unit 106, and also receives information on the information processing devices in the abnormal state. Are transferred to the output buffer 107. The editing unit 106 deletes, from the response message transferred from the receiving unit 105, the response that does not correspond to the operation command transmitted from the delivery unit 103. Further, when there are the same responses corresponding to the same operation command, the response is edited so as to be collectively displayed in one response message, and the different responses are edited so as to be displayed as a single message.

The output buffer 107 stores the response message edited by the editing unit 106 and the state information passed from the receiving unit 105. The display unit 108 has an output buffer 1
The response message and status information stored in 07 are displayed under the control of the operation application program 101 or predetermined control.

FIG. 4 is a sequence chart showing the operation of the present invention. In the sequence chart described below, it is assumed that the operation command is transferred from the operation terminal 100 to the two normally operating information processing apparatuses A and B. Step 100) The operation terminal 100 uses the destination list 10
2, information processing devices A and B that are operating normally
To get the ID.

Step 200) The delivery unit 103 of the operation terminal 100 transfers the operation command to the acquired information processing devices A and B. Step 300) The information processing apparatuses A and B that have received the operation command transmit a response message to the operation command to the operation terminal 100.

Step 400) When the receiving unit 105 of the operation terminal 100 receives the response message from the information processing devices A and B, it refers to the reception list 104 and determines whether the response message is an abnormal response or a normal response. Then, the response result of the normal response or the abnormal response is transferred to the editing unit 106 together with the response message. When the response is a normal response, the editing unit 106 determines whether the response message corresponds to the operation command. Response messages that do not correspond to operation commands are rejected. Here, the response messages that correspond to the operation command transmitted by the response message and are the same are grouped as one message, and
Other messages corresponding to the operation command are stored in the output buffer 107 as they are and displayed on the display unit 108 as appropriate.

Next, the delivery unit 103 of the operation terminal 100
Will be described. The sequence chart shown in FIG. 4 corresponds to the process of step 100. FIG. 5 is a flowchart showing the processing of the delivery unit of the present invention. (Step 101) The delivery unit 103 acquires an operation command to be transferred to the information processing apparatus 300 from the operation application program 101.

Step 102) Next, the destination list 10
The ID of the normal destination information processing apparatus 300 and the destination address of the information processing apparatus 300 are all acquired from 2. (Step 103) If the ID of the normal destination information processing apparatus 300 cannot be acquired from the destination list 102, the process proceeds to Step 105. If the ID can be acquired, Step 1 is performed.
Move to 04.

Step 104) The operation command is transmitted to the read ID of the destination information processing apparatus. Step 105) Since all the states of the information processing device are abnormal, an error message indicating that the ID of the information processing device has not been read is output to the output buffer 107.

Next, the operation of the receiving section 105 will be described. In the sequence chart shown in FIG.
Corresponds to 0. FIG. 6 is a flowchart showing the processing of the receiving unit of the present invention. Step 301) The reception unit 105 receives the reception list 104.
With reference to, it is determined whether or not the states of all the information processing devices 300 are abnormal. Here, if it is abnormal,
The process proceeds to step 302, and if not, the process proceeds to step 303.

Step 302) All information processing devices 3
If 00 is abnormal, the output buffer 10
Transfer to 7. At this time, the reception unit 105 determines that the reception list 1
Information processing device 3 in which "abnormal" is set in 04
The ID of 00 and the abnormal state are transferred to the output buffer 107.

Step 303) All information processing devices 3
If 00 is not abnormal, the response message from the information processing device 300 is received. Step 304) Referring to the reception list 104, if the responses are received from all the normal information processing apparatuses 300, the process proceeds to step 305, and if not, the process proceeds to step 303 to obtain the next response. To receive.

Step 305) Normal information processing device 3
The response from 00 is transferred to the editing unit 106. Next, the operation of the editing unit 106 will be described. The above sequence chart shown in FIG. 4 corresponds to step 400. FIG. 7 is a flowchart showing the processing of the editing unit of the present invention.

Step 401) The editing section 106 acquires the response message received from the normal information processing apparatus from the receiving section 105 and the response result of the information processing apparatus in the abnormal state. Here, the response result of the information processing device in the abnormal state means that the delivery unit 103 does not transmit the operation command to the information processing device in the abnormal state, and therefore the response from the information processing device is Absent. However, when “abnormal” is set in the reception list 104, it is assumed that the information of the information processing apparatus in the abnormal state has been transferred from the reception unit 105 to the output buffer 107.

Step 402) The editing unit 106 deletes the response message transferred from the receiving unit 105 that does not correspond to the transmitted operation command. (Step 403) For each response, it is compared with the response of the operation command previously stored in the output buffer 107, and it is determined whether or not there is a match. If they match, the process proceeds to step 405, and there is a mismatch. If so, step 40
Move to 4.

Step 404) If the response message does not match the previously stored response message, the response message is stored in the output buffer 107, and step 406
Move to Step 405) If the response message is the same as the response message previously stored in the output buffer 107, the message can be aggregated, so the message is deleted and the process proceeds to step 403.

Step 406) If all the response messages have been compared with the response messages stored in the output buffer 107, the process proceeds to step 407, and if not completed, the process proceeds to step 403. Step 407) The response message stored in the output buffer 107 is displayed on the display unit 108.

As a result, the same response message received from a plurality of information processing devices 300 is aggregated and displayed as one message, and different response messages are displayed as other messages.

_FourIs “64”.

FIG. 9 shows an example of a destination list according to an embodiment of the present invention. In the figure, the information processing device ID is "62".
This indicates that the information processing device 300 ₂ is in an abnormal state. In this embodiment, it is assumed that the destination list 102 and the reception list 104 have the same contents.

FIG. 10 shows the transmission status of the operation command and the reception status of the response message according to the embodiment of the present invention. Less than,
A specific operation will be described with reference to FIGS. (1) The delivery unit 103 of the operation terminal 100 refers to the destination list 102 shown in FIG. 9 to determine the destination to which the operation command A should be transmitted. In this embodiment, the IDs of the information processing devices are “61”, “63”, and “64”. The ID “62” of the information processing device 300 is the destination list 1 shown in FIG.
Since the status is "abnormal" as indicated by 02, the command is not transmitted.

(2) The delivery unit 103 issues an operation command "A" to the information processing device 300 of the determined destination.
Send (3) The reception unit 105 of the operation terminal 100 acquires a response message from each of the information processing devices 300 having the IDs “61”, “63”, and “64” that transmitted the operation command. In the example of FIG. 10, the response message a is received from the information processing apparatus 300 _{1 with} ID = 61, the response message a is received from the information processing apparatus 300 _{3 with} ID = 63, and the response message b is received from the information processing apparatus 300 _{4 with} ID = 64. .

(4) Receiver 105 of operation terminal 100
Upon receiving these response messages, will refer to the reception list 104. In this embodiment, the reception list 104
Is the same as the contents of the destination list 102 shown in FIG. 9, the ID of the information processing device in which the abnormality has occurred is “62”.
Therefore, the response message from ID = 62 has not been received. Therefore, “abnormal” is output as a message to the output buffer 107 as a response of ID = 62.

(5) The receiving unit 105 transfers the received response messages a and b to the editing unit 106. (6) The editing unit 106 selects the response message a corresponding to the operation command “A” from the response messages a and b.
Only the selected response message b is discarded.

(7) The editing unit 106 uses the information processing device I
Output the response message “a” from D = 61 to output buffer 1
07. (8) Next, when the response message “a” from the information processing device ID = 63 is acquired and compared with the response message “a” stored in the output buffer 107, the response message is the same, so ID = The response message from 63 is deleted.

(9) Since the comparison of the response messages from all the information processing devices is completed, the response message "a" stored in the output buffer 107 and the information of the information processing device of ID = 62 in the abnormal state are displayed. This is displayed on the section 108. Next, the following response message is sent to each information processing device 3
The case of receiving from 00 will be described.

As the ID of each information processing device 300, 6
It is assumed that there are 1, 62, 63, 64, 65, 66 and 67. Of these, it is assumed that the state of ID = 62 is abnormal in the destination list 102 and the reception list 104. Therefore, the IDs of the information processing devices of the destinations to which the operation terminal 100 transmits the commands are 61, 63, 64,
It becomes 65, 66, 67.

It is assumed that the operation terminal 100 transmits the operation command A and the following response message is returned from each information processing apparatus 300, and the response messages a and b correspond to the operation command A. ID = 61 ... Response message a ID = 63 ... Response message a ID = 64 ... Response message b ID = 65 ... Response message c ID = 66 ... Response message a ID = 67 ... Response message d In the above example, edit The unit 106 has ID = 6
5, the response messages c and d received from ID = 67 are messages that do not correspond to the operation command A and are therefore discarded. The response messages a and b are the operation command A.
Since the message corresponds to, it is acquired. Of these, three response messages a have been received, so these response messages are combined into one, and the output buffer 107
Then, another type of response message b is stored in the output buffer 107.

The information of the information processing device of ID = 62 which is in an abnormal state is also stored in the output buffer 107 by the receiving unit 105. Therefore, the output buffer 107 finally stores one response message a and one response message b, and also stores the ID and status information of the information processing apparatus in the abnormal state. Next, the display unit 108 displays the display as shown in FIG. The response messages a and b and information of the information processing device in the abnormal state are also displayed.

As described above, according to the present embodiment, the operation command is transmitted from the operation terminal 100 to all the information processing apparatuses 300 operating normally, and the response message received from each information processing apparatus 300 When the same response message corresponding to the operation command is acquired, those response messages are displayed together as one, and different response messages are displayed separately so that the number of displayed response messages can be reduced. It can be reduced.

Further, since the information indicating the abnormality is also displayed for the information processing apparatus in the abnormal state, even if the operation command is transmitted, the response does not arrive due to timeout, or the response due to the abnormality due to a failure or the like. It is possible to grasp the status of whether or not it has arrived.

The present invention is not limited to the above embodiments, but various modifications and applications are possible within the scope of the claims.

[0047]

As described above, according to the method and apparatus for realizing the operation command in the distributed system of the present invention, the following effects can be obtained. (1) When the configuration of the information processing device is changed or local maintenance is performed, it is possible to prevent the contradiction of the processing of the operation command due to an error in updating the information holding unit. Further, according to the present invention, the information amount of the operation command is small, the information amount of the response from the information processing device not related to the operation command is small, and the frequency of inputting the operation command is not usually high, so that the load on the network is reduced. Is slightly increased,
It doesn't matter.

(2) Status of each information processing device (normal /
By holding the "abnormality", when one abnormal information processing apparatus is in an abnormal state, the status (normal / normal) of each information processing apparatus is retained.
Since it is not necessary to wait until the response times out, the response time can be shortened and the responsiveness is improved as compared with the case where (abnormal) is not held.
