Description

The present invention relates to information processing in a plurality of intranets connected by a network, and relates to an information processing apparatus that synchronizes updates of shared information such as documents, an information processing method thereof, and an information processing program thereof.

  Information is shared between intranets connected by networks such as the Internet, but the shared information is maintained and managed in the same state by file transfer such as FTP (File Transfer Protocol) (synchronization) ) Was common. However, when going through a network, it is necessary to pass through various security measures installed in each intranet. If each network is a network of an organization with a different security policy, sharing information is technically difficult and procedurally troublesome.

  Regarding information sharing between such intranets, when information is shared between the Internet or between a plurality of intranets, by collecting information in one information management server, it is collectively managed by the information management server, Some are disclosed to users of different organizations from the server or from a public server that discloses information (Patent Documents 1 and 2).

In addition, for updating each database between intranets, the update information is notified (Patent Document 3), the information is updated via e-mail (Patent Documents 4, 5, 6, 7, 8). ) In addition, there is a technique in which information is shared by transmitting the information mutually by e-mail, and the transmitted schedule is displayed on a schedule display device (Patent Document 9).

JP 2000-311204 A JP 2002-373225 A JP 2000-148611 A JP 2000-285074 A JP 2003-150438 A JP-A-11-150532 JP 2000-207305 A JP 2003-16019 A JP2002-49567

  By the way, when information shared by multiple intranets is managed separately in each intranet, the information can be updated individually in each intranet, the update information of the information is not reflected in other intranets, etc. There is a problem that the shared information is inconsistent. Such inconvenience is particularly noticeable when information is shared between intranets having networks with different security policies. In addition, regarding shared information between intranets, when information to be shared is updated based on an update request, if there is no notification, it is difficult to confirm the update of the information. To maintain the same information shared between multiple intranets that have access restrictions from the outside, communication between intranets is required, but it is difficult to pass security regulations (firewall proxy). In particular, when regulations with different security policies are applied, it takes time to share information beyond the security regulations.

  In addition, it is possible to scrutinize information being shared between intranets by accessing the information from other intranets, such as updating the information, but security regulations make it difficult to scrutinize the information. There's a problem.

  Also, as the number of intranets sharing information increases, it takes time to receive access requests and access results for each intranet, and communication takes time and response is delayed. There is also a problem of becoming.

  There is no disclosure or suggestion in the above-mentioned patent documents 1 to 9 regarding such problems and means for solving such problems.

  Therefore, the present invention relates to information processing in a plurality of intranets connected by a network, and an object thereof is to synchronize updates of shared information of a plurality of intranets and prevent update processing conflicts.

To describe such an object in detail, it relates to information processing in a plurality of intranets connected by a network and to prevent simultaneous processing of information update of each intranet.

  To achieve the above object, an information processing apparatus according to the present invention is an information processing apparatus that exists in an intranet that shares information with an information processing apparatus that exists in another intranet connected by a network, and stores the information. The information updating unit that receives the information update request, and whether or not the information is updatable based on the update request of the information update unit. An information management unit that sets non-updatable and updates the information in synchronization with an information processing apparatus existing in another intranet, and requests the non-updatable setting to the information processing apparatus existing in the other intranet Then, it is determined whether or not the information in the information processing apparatus existing in the other intranet is in an updatable state, and the other intranet in the updatable state is determined. The information processing apparatus existing in the network is set to be non-updatable and the setting completion of the non-updatable is notified, and the setting completion is notified from the information processing apparatus existing in the other intranet before a predetermined time elapses. In the case where the update request for the information is transmitted to the information processing apparatus existing in the other intranet, and the setting completion is not notified from the information processing apparatus existing in the other intranet even after a predetermined time has elapsed. And an information synchronization unit that transmits the non-updatable release request to an information processing apparatus existing in the other intranet and causes the information management unit to release the non-updatable information.

  According to such a configuration, regarding the update of information shared with other intranets connected by a network, it is determined whether or not the information is in an updatable state, and the intranet in which the information is in an updatable state is determined. The update prohibition is set, and the information is updated in synchronization with information processing apparatuses existing in other intranets. This non-updatable process is a process for refusing an update request from another, indicating that the information has been transferred to the update process, in other words, a process of declaring that the update is in progress. In response to this, the information processing apparatus existing in the other intranet is requested to be set to be non-updatable, and all the information processing apparatuses existing in the intranet connected by the network are set to be non-updatable within a predetermined time. The shared information can be updated by notifying the completion of the non-updatable setting. By such processing by the information synchronization unit, when update processing competes with an information update request as a trigger, priority is generated between intranets, and simultaneous update of information is prevented. This does not prevent the update of information, but the update of information is performed according to the order, and the information update of the intranet that is set to be unupdatable first in response to the information update request is processed with priority. As a result, contention update conflicts are prevented, and no mismatch occurs in shared information between intranets. Reliable information update is realized.

  In order to achieve the above object, a mail transmission / reception unit that uses an e-mail to transmit the notification indicating the setting request for non-updatable, the notification indicating the cancellation request for non-updatable, and the update request for the information is provided. It is good also as a structure. With such a configuration, when the same information is shared between intranets where access from the outside is restricted, the information can be updated by electronic mail.

  To achieve the above object, an information processing method of an information processing apparatus according to the present invention is an information processing method of an information processing apparatus existing in an intranet that shares information with an information processing apparatus existing in another intranet connected by a network. A process for receiving an update request for the information stored in the storage unit, a process for determining whether or not the information is in an updatable state based on the update request, and the information in an updatable state In the case where the information is not updated, the information is updated in synchronization with an information processing apparatus existing in another intranet sharing the information, and the information processing apparatus existing in the other intranet It is determined whether or not the information is in an updatable state, and the information processing apparatus existing in the other intranet in the updatable state is set to the non-updatable setting. And when the completion of setting is notified from an information processing apparatus existing in the other intranet before a predetermined time elapses, the request is made in the other intranet. When the update request for the information is transmitted to the information processing apparatus, and the completion of the setting is not notified from the information processing apparatus existing in the other intranet even after a predetermined time has elapsed, the information processing existing in the other intranet And a process of transmitting the non-updatable release request to the apparatus and releasing the non-updatable information.

  With such a configuration, when the information stored in the storage unit is updated, if the information is in an updatable state, the update is disabled, so that an update request from another intranet can be excluded. it can. From an intranet in which non-updatable is set, an information processing apparatus existing in another intranet in which the information is updatable is requested to make a non-updatable setting. In this case, if the information processing apparatus existing in another intranet has already been set to non-updatable, the non-updatable setting request is rejected. Then, when the non-updatable setting is established for all of the information processing apparatuses existing in the other intranet, the information update request is accepted, and the information is updated. According to such an information processing method, priority is given to update processing triggered by an information update request, and simultaneous processing of different updates and conflicting updates to the information is prevented. As a result, shared information between intranets can be maintained in the same state.

In order to achieve the above object, an information processing program of an information processing apparatus of the present invention is an information processing program of an information processing apparatus that exists in an intranet that shares information with an information processing apparatus that exists in another intranet connected by a network. A step of accepting an update request for the information stored in the storage unit, a step of determining whether the information is in an updatable state based on the update request, and an updatable state of the information Updating the information in synchronization with an information processing apparatus existing in another intranet that shares the information, and the information processing apparatus existing in the other intranet It is determined whether the information is in an updatable state, and information processing existing in the other intranet in the updatable state is performed. A step of requesting the device to perform the non-updatable setting and the non-updatable setting completion notification, and when the setting completion is notified from an information processing device existing in the other intranet before a predetermined time elapses, When the update request for the information is transmitted to an information processing apparatus existing in another intranet, and the completion of setting is not notified from the information processing apparatus existing in the other intranet even after a predetermined time has elapsed, And a step of transmitting the non-updatable release request to an information processing apparatus existing in the intranet and releasing the non-updatable information, and causing the computer to execute these steps. With such a configuration, as described above, information can be updated between intranets that share information with other intranets connected via a network.

  Therefore, according to the present invention, the following effects can be obtained.

  (1) It is possible to prevent conflicts between intranets in the update processing of shared information, and it is possible to avoid inconsistencies in information due to the complexity of update processing, and to improve the reliability of shared information between intranets.

  (2) In this intranet, when the control unit updates the information in the storage unit, if the information is in an updatable state, the non-updatable setting is set and the other intranet is in an updatable state. If it is configured to be released in the case of, it is possible to accept a non-updatable setting request from other intranets, and to prevent complication of information update between intranets.

(3) In this intranet, if the e-mail is used to update the notification and the information indicating the non-updatable setting request issued from the control unit, the same information can be shared between intranets where access from outside is restricted. Even in the case of sharing, information can be quickly updated by e-mail.

  An intranet information processing system according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing an information processing system for an intranet.

  This information processing system 2 shares information such as documents among a plurality of intranets, and prevents conflicts in updating the information. A shared information synchronization system in which a plurality of intranets are connected by a network such as the Internet. Is configured. In this embodiment, for ease of explanation, two intranets 41 and 42 are installed as a plurality of intranets, and these intranets 41 and 42 are connected via the Internet 6.

  Each of the intranets 41 and 42 includes a plurality of computers as information processing apparatuses that perform information processing. The intranet 41 includes an information synchronization server 100, a file server 102, an e-mail transmission / reception server 104, and the like. The intranet 42 includes an information synchronization server 200, a file server 202, an e-mail transmission / reception server 204, and the like. In the intranets 41 and 42, the information display / update units 106 and 206 are configured by, for example, document editing software in a client machine in the intranet such as a personal computer (PC). The information display / update unit 106 performs either or both of information display and update processing, and in this case, receives an update request for information shared with the intranet 42. Similarly, the information display / update unit 206 performs either or both of information display and its update, and in this case, receives an update request for information shared with the intranet 41.

  The information synchronization unit 108 corresponds to one program in the information synchronization server 100. The information synchronization unit 108 executes a non-updatable setting request, determination processing for determining whether information can be updated, or the like for the intranet 42 in response to an information update request. Similarly, the information synchronization unit 208 corresponds to one program in the information synchronization server 200. The information synchronization unit 208 executes a non-updatable setting request, determination processing for determining whether or not information can be updated, and the like for the intranet 41 in response to the information update request. Here, “unupdateable” is a process for rejecting an update request from another, indicating that the information has been transferred to the update process, in other words, a process of declaring that the update is in progress.

  The mail generation unit 110 corresponds to a program in the information synchronization server 100. The mail generation unit 110 generates an e-mail that notifies various requests such as a request for setting information that cannot be updated to the intranet 42, an information update request, and other information. Similarly, the mail generation unit 210 corresponds to a program in the information synchronization server 200. The mail generation unit 210 generates an e-mail that notifies various requests such as a request for setting no information update to the intranet 41, an information update request, and other information.

  The mail analysis unit 112 corresponds to a program in the information synchronization server 100. This mail analysis unit 112 analyzes the content of the email notified from the intranet 42 and transfers the result to the information synchronization unit 108. Similarly, the mail analysis unit 212 corresponds to a program in the information synchronization server 200. The mail analysis unit 212 analyzes the content of the email notified from the intranet 41 and transfers the result to the information synchronization unit 208.

  The information management unit 114 is in the file server 102 and manages various information and constitutes an input / output unit for various information. In response to a request for information update from the information display / update unit 106, the information management unit 114 performs a non-updatable setting process, a setting release process thereof, a non-updatable setting request for the intranet 42, a request for releasing the setting, and the like Execute. Similarly, the information management unit 214 is in the file server 202 and is responsible for managing various types of information and constitutes an input / output unit for various types of information. In response to a request for information update from the information display / update unit 206, the information management unit 214 performs an unrenewable setting process, a setting release process thereof, a non-updatable setting request for the intranet 41, a request for releasing the setting, and the like. Execute.

  The shared information area 116 is an information storage area set on the file server 102, and constitutes a first storage unit that stores information 118 shared between the intranets 41 and 42. In this case, the information 118 is information A. The information management area 120 is an information storage area set on the file server 102 and constitutes a second storage unit that stores information management data 122 that is information for managing the information 118 described above. is doing. The information management data 122 corresponds to the information A and is information management data A. The shared information area 116 and the information management area 120 constitute a database 124 for storing information 118 shared between the intranets 41 and 42 and information management data 122 thereof. This database 124 may be installed outside the file server 102. Corresponding to the database 124, in this embodiment, the control unit that executes the update processing of the shared information is configured by the information management unit 114 of the file server 102 together with the information synchronization server 100.

  Such a configuration is the same on the intranet 42 side, and the shared information area 216 is an information storage area set on the file server 202, and stores the information 218 shared between the intranets 41 and 42. The memory | storage part is comprised. In this case, information 218 is information A. The information management area 220 is an information storage area set on the file server 202, and constitutes a second storage unit that stores information management data 222 that is information for managing the information 218 described above. is doing. The information management data 222 corresponds to the information A and is information management data A. The shared information area 216 and the information management area 220 constitute a database 224 that stores information 218 shared between the intranets 41 and 42 and information management data 222 thereof. This database 224 may also be installed outside the file server 202. Similar to the intranet 41, this embodiment corresponds to the database 224, and in this embodiment, a control unit that executes shared information update processing is configured by the information management unit 214 of the file server 202 together with the information synchronization server 200.

  The mail transmission / reception unit 126 transmits / receives electronic mail to / from the intranet 42 side, and the mail transmission / reception unit 226 transmits / receives electronic mail to / from the intranet 41 side.

  According to such a configuration, shared information between the intranets 41 and 42 is individually stored in the shared information areas 116 and 216, and this shared information can be updated by a request from the intranets 41 and 42. . In order to prevent the information stored in the shared information areas 116 and 216 from becoming inconsistent if such an update is left unattended, a rule is given to the update process. That is, when the information 118 is updated, for example, when the information 118 is in an updatable state on the intranet 41 side, the update is set to be non-updatable, and the intranet 42 having the information 218 in common with the information 118 is set to non-updatable. It is possible to update the information 118 and 218 on the condition that all the intranets 41 and 42 for the requested information 118 and 218 to be shared are set as non-updatable. In this case, if non-updatable is already set on the intranet 42 side, the non-updatable setting request on the intranet 41 side is rejected, and the update request from the intranet 42 side is accepted, and the update request on the intranet 41 side is accepted. Is executed after the update process on the intranet 42 side.

  By executing such an update process, information update conflicts are prevented, and there is no discrepancy between shared information between intranets, and reliability of information shared between intranets is maintained along with highly reliable information updates. Will be.

  Details of information processing such as information updating will be described with reference to FIG. FIG. 2 shows an example of an information processing method between intranets and a processing procedure of an information processing program.

  As a premise of the information update, for example, in the intranet 41, when the information display / update unit 106 refers to the information management unit 114 with respect to the information 118, the information management unit 114 reads the information 118 in the shared information area 116. Is called. Assume that an update request for the information 118 is generated from the information display / update unit 106 to the information management unit 114.

  Therefore, in the intranet 41, it is determined whether or not non-updatable is set in the information management unit 114 (step S1). In this determination processing, the information management data 122 corresponding to the information 118 in the shared information area 116 is read from the information management area 120, and whether or not the information 118 can be updated is set in the information management data 122 (F = 1 or F = 0) is determined (step S2), and if the update impossibility is not set (F = 0), that is, if the information 118 is in an updatable state, the information management data 122 cannot be updated for the information 118. Is set (step S3). After this setting, a setting request for non-updatable is made to the intranet 42 (step S4). This request is notified to the mail generation unit 110 through the information synchronization unit 108, and an e-mail representing a setting request that cannot be updated is generated by the mail generation unit 110 (step S5). The e-mail representing the non-updatable setting request is transmitted to the intranet 42 through the Internet 6, and the response is received by e-mail (step S6). In this case, when the notification of the e-mail is incomplete, the above-described non-updatable state is canceled and the setting is performed (step S7).

  When the mail transmission / reception unit 126 receives an e-mail from the intranet 42, the received mail is transferred to the mail analysis unit 112, and mail analysis is executed (step S8). The result of the mail analysis is transferred to the information synchronizer 108, and it is determined whether or not the non-updatable setting has been made on the intranet 42 side (step S9). In other words, when the update request on the intranet 41 side is triggered and no update is set on the intranet 42 side, the information 218 can be updated. In this case, since whether or not the information 118 can be updated has already been determined, it is determined from the mail analysis result whether or not the information 218 on the intranet 42 side can be updated (step S10). In the same manner as in step S7, cancellation of non-updatable is set (step S11), and if updatable, the information 218 on the intranet 42 side is updated (step S12). In order to update this information, the information synchronizer 108 requests the mail generator 110 to generate an e-mail indicating the notification (step S13), and the e-mail is transferred from the mail transmitter / receiver 104 to the intranet 42 via the Internet 6. .

  The e-mail received by the mail transmitting / receiving unit 226 is transferred to the mail analyzing unit 212, the contents of which are analyzed, and it is confirmed that an update request for the information 218 has been received. As a result, the update of the information 218 of the intranet 42 is executed, the completion of the update is transferred from the information management unit 214 and the information synchronization unit 208 to the mail generation unit 210, and an e-mail indicating the completion notification is generated by the mail generation unit 210 Is done. This e-mail is transmitted from the mail transmission / reception unit 226, received by the mail transmission / reception unit 126 of the intranet 41 through the Internet 6, analyzed by the mail analysis unit 112, and the information synchronization unit 108 has completed the update of the information 218 on the intranet 42 side. To be notified. Receiving this notification, the information management unit 114 updates the information 118 (step S14). After this information update, the previously set non-updatable state is canceled, the state is changed to the updatable state, and the information management unit 114 notifies the information display / updating unit 106 of the update completion (step S15). The information display / update unit 106 is notified that the information 118 is in an updatable state, and the process ends.

  If it is determined in step S2 that the update is impossible, and if the update disable setting is performed in steps S7 and S11, the information management unit 114 notifies the information display / update unit 106 that the update is not completed ( In step S16), the information display / update unit 106 is notified that the information 118 is in an updatable state, and the process ends.

  The above processing procedure has been described when the update request for the information 118, 218 occurs on the intranet 41 side, but the same processing is performed for the process when the update request for the information 218, 118 occurs on the intranet 42 side. Is called.

  Next, information processing on the intranet side requested to be set to be non-updatable will be described with reference to FIG. FIG. 3 shows an example of an information processing method on the side of the intranet 42 that has been requested to be set for non-updatable and a processing procedure of the information processing program.

  When an e-mail representing a setting request that cannot be updated is transmitted from the intranet 41, and this e-mail is received by the intranet 42, the e-mail is transferred from the mail transmitting / receiving unit 226 to the mail analyzing unit 212 and analyzed. The information synchronization unit 208 is notified. Therefore, the information synchronization unit 208 reads the information management data 222 from the information management area 220 through the information management unit 214, and determines that updating is not possible (step S21). In this determination process, it is determined whether or not the information 218 is not updatable in the information management data 222 (step S22). When the information 218 is in an updatable state and the updatable setting is not set. In (F = 0), the non-updatable information 218 is set in the information management data 222 (step S23). When this update impossibility is set, an e-mail as a completion notification is created in the mail generation unit 210 (step S24), and the e-mail is transmitted from the mail transmission / reception unit 226 to the intranet 41.

  Further, if the information management data 222 has already been set to the information management data 222 before the information 218 can be updated before the non-updatable setting request from the intranet 41, the information cannot be updated in the determination of step S22. In other words, when the information 218 is in the non-updatable state and the non-updatable setting is made (F = 1), the non-updatable setting cannot be set on the information 218. Therefore, when the update impossibility cannot be set, an e-mail as the incompletion notification is created in the mail generation unit 210 (step S24), and the e-mail is transmitted from the mail transmission / reception unit 226 to the intranet 41.

  Although the above processing procedure has been described when the intranet 42 side receives a setting request that cannot be updated, the processing when the intranet 41 side receives a setting request that cannot be updated is similarly performed.

  Next, information processing on the intranet side requested to update information will be described with reference to FIG. FIG. 4 shows an example of an information processing method such as information update on the intranet 42 side that has received a request for information update, and a processing procedure of the information processing program.

  When the e-mail from the intranet 42 is received by the intranet 41 and the information synchronization unit 108 receives a setting completion notification that cannot be updated, the intranet 42 determines that the information 218 can be updated, and updates the information 218. Processing begins. In this process, when the information management unit 114 that has received an update request for the information 118 and 218 holds information a for the information A as information to be updated, the information a is sent to the mail generation unit 110 through the information synchronization unit 108. Then, the mail generation unit 110 generates an electronic mail for transmitting the information a. This e-mail is transmitted from the mail transmitting / receiving unit 126 toward the intranet 42 and received by the mail transmitting / receiving unit 226 through the Internet 6.

  In the intranet 42 that has received the electronic mail, the electronic mail is transferred from the mail transmission / reception unit 226 to the mail analysis unit 212, and the contents of the notification are analyzed. The analysis result is notified to the information synchronization unit 208 and the information 218 is updated (step S31). The information synchronization unit 208 requests the information management unit 214 to update the information A of the information 218 in the shared information area 216 to the information a. The information management unit 214 updates the information A to information a, and upon completion of the update, the information management unit 214 cancels the non-updating of the information 218 of the intranet 42 (step S32). That is, for the information management data 222 in the information management area 220, the information 218 is changed from the non-updatable state (F = 1) to the updatable state (F = 0).

  Then, the update completion of the information 218 is notified from the intranet 42 to the intranet 41 by electronic mail. In response to this, the information synchronization unit 108 of the intranet 41 requests the information management unit 114 to update the information A to the information a based on the update completion notification of the information 218 from the intranet 42. As a result, the information A of the information 118 on the intranet 41 side is also updated to the information a, and the information 118 is changed from the non-updatable state (F = 1) to the updatable state (F = 0). In this case, for ease of explanation, the two intranets 41 and 42 are described. However, when there are a plurality of intranets, reply records from all the intranets sharing the information A in addition to the intranet 42 are recorded. The information 118 is stored, and the information 118 is updated in response to the update completion reply.

  The above processing procedure has been described when the intranet 42 receives an update request. However, the processing when the update request from the intranet 42 is received by the intranet 41 is the same.

  Next, the relationship between each process between the intranets 41 and 42 and each unit will be described with reference to FIGS. 5, 6, 7, 8, and 9. FIG. 5 is a diagram showing the configuration of the non-updatable setting request process, FIG. 6 is a diagram showing the configuration of the non-updatable setting completion notification process, FIG. 7 is a diagram showing the configuration of the information update process, and FIG. FIG. 9 is a diagram showing a configuration of response processing in the information update processing, and FIG. 9 is a diagram showing a configuration of non-updatable release processing. In each figure, components that mainly function in each process and a data flow are indicated by bold lines.

  In the setting request processing for non-updating information 118 and 218 shared between the intranets 41 and 42, as shown in FIG. 5, when an update request for information 118 occurs, the information display / update unit 106 sends information management unit 114. The information synchronization unit 108 is requested to update the information 118 (R1, R2). In response to this update request, the information synchronization unit 108 requests the information management unit 114 to read the information management data 122 in the information management area 120 corresponding to the information 118 in the shared information area 116 (R3). Upon receiving this request, the information management unit 114 reads the information management data 122 from the information management area 120 (R4), and notifies the information synchronization unit 108 of the read information management data 122 (R5). The information management unit 114 determines whether or not the information 118 can be updated (F = 1) for the information management data 122 (F = 0). When update disabled is set (F = 1), update is in progress, so that another update request cannot be accepted, that is, update incompletion notification as a notification that the information 118 cannot be updated. Is notified to the information management unit 114, and the information display unit 114 notifies the information display / update unit 106 to that effect.

  If the information management data 122 is not set to be non-updatable (F = 0), the information synchronization unit 108 requests the information management unit 114 to set the non-updatable (R6). Based on this request, non-updatable (F = 1) is set in the information management data 122 (R7). Based on this setting, the information synchronization unit 108 makes a transmission request to the mail generation unit 110 to notify the intranet 42 sharing the information 118 of a setting request that cannot be updated (R8). In this case, if there is an intranet that shares the information 118 other than the intranet 42, a request for a non-updatable setting notification is requested to the intranet. The mail generation unit 110 creates an e-mail representing a setting that cannot be updated, and the mail transmission / reception unit 126 is requested to send the e-mail (R9). An e-mail is transmitted from the mail transmitting / receiving unit 126 to the intranet 42 (R10).

  An electronic mail is received by the mail transmission / reception unit 226 of the intranet 42 via the Internet 6 (R11), and the received mail is notified to the mail analysis unit 212 (R12). The analysis result of the mail analysis unit 212 is notified to the information synchronization unit 208 (R13). In the information synchronization unit 208, a determination process for non-updatable settings is executed, the information management unit 214 is requested to read the information management data 222 (R14), and the information management data 222 is read from the information management area 220. (R15), the information management data 222 is notified to the information synchronization unit 208 through the information management unit 214 (R16). The information synchronization unit 208 requests the information management unit 214 to set the information management data 222 in the information management area 220 to be non-updatable (R17), and the information management data 222 is set to be non-updatable (R18). .

  Next, in the setting completion notification processing for not updating the information 218 shared between the intranets 41 and 42, the configuration is as shown in FIG. When the non-updatable setting (FIG. 5) is completed, the process proceeds to a non-updatable setting completion notification process, and the information generation unit 208 notifies the mail generation unit 210 of the non-updatable setting completion (R19). In response to the notification, the mail generation unit 210 creates an e-mail indicating a setting completion notification that cannot be updated, requests the mail transmission / reception unit 226 to send an e-mail (R20), and sends the e-mail from the mail transmission / reception unit 226. (R21). The electronic mail is received by the mail transmitting / receiving unit 126 of the intranet 41 through the Internet 6 (R22), and the received mail is transferred to the mail analyzing unit 112 (R23) and analyzed. The analysis result is notified to the waiting information synchronizer 108 (R24). Note that the process of notifying the setting is performed in the same manner.

  Next, in the information update process, as shown in FIG. 7, the information synchronization unit 108 requests the information management unit 114 to acquire the information a to be updated from the information 118 (R27). In response, the information management unit 114 acquires the information a to be updated from the shared information area 116 (R28) and notifies the information synchronization unit 108 of the information a. Further, the information synchronizer 108 notifies the mail generator 110 of information update for the intranet sharing the information A (R29). In response to the notification, the mail generation unit 110 creates an e-mail indicating that the information A is rewritten to the information a, requests the e-mail transmission / reception unit 126 to send an e-mail (R30), and receives the e-mail from the e-mail transmission / reception unit 126. It is transmitted (R31). The electronic mail is received by the mail transmission / reception unit 226 of the intranet 42 through the Internet 6 (R32), and the received mail is transferred to the mail analysis unit 212 (R33) and analyzed. The analysis result is notified to the information synchronization unit 208 (R34). The information synchronization unit 208 requests the information management unit 214 to update the information A in the information 218 to the information a (R35), and the information management unit 214 uses the information A from the information 218 in the shared information area 216. Information update to information a is performed (R36). Also, the information synchronization unit 208 requests the information management unit 214 to change the information management data 222 from the non-updatable state to the updatable state (R37). The information management data 222 in the area 220 is changed from the non-updatable state (F = 1) to the updatable state (F = 0) (R38).

  Next, in the information update response process, as shown in FIG. 8, after the information update process, a request for an update completion notification is generated from the information synchronization unit 208 to the mail generation unit 210 (R39). In the mail generation unit 210, an e-mail representing an update completion notification is created, a mail transmission request is issued to the mail transmission / reception unit 226 (R40), and mail transmission is performed from the mail transmission / reception unit 226 (R41). The electronic mail is received by the mail transmission / reception unit 126 of the intranet 41 through the Internet 6 (R42), and the received mail is transferred to the mail analysis unit 112 (R43) and analyzed. The analysis result is notified to the information synchronization unit 108 (R44). The information synchronization unit 108 requests the information management unit 114 to update the information A of the information 118 to the information a (R45), and the information management unit 114 starts from the information A of the information 118 in the shared information area 116. Information update to information a is performed (R46). In addition, the information synchronization unit 108 requests the information management unit 114 to change the information management data 122 from the non-updatable state to the updatable state (R47). The information management data 122 in the area 120 is changed from the non-updatable state (F = 1) to the updatable state (F = 0) (R48). Then, the information management unit 114 sends an update completion notification to the information display / update unit 106 (R49).

  Next, the information non-updatable release process has the configuration shown in FIG. When the information synchronization unit 108 receives a notification indicating that the non-updatable setting is incomplete, among the intranets that share the information 118 of the shared information area 116 of the intranet 41, the non-updatable release is generated for the intranet for which the non-updatable setting has been completed. The unit 110 is notified (R50). Upon receiving this notification, the mail generation unit 110 creates an e-mail representing a non-updatable release notification, and makes a transmission request (R51). The electronic mail is transmitted from the mail transmitting / receiving unit 126 that has received the transmission request (R52). The electronic mail is received by the mail transmitting / receiving unit 226 of the intranet 42 through the Internet 6 (R53), and the received mail is transferred to the mail analyzing unit 212 (R54) and analyzed. As an analysis result, the mail analysis unit 212 notifies the information synchronization unit 208 of a non-updatable release request (R55). The information synchronization unit 208 requests the information management unit 214 to cancel the non-update of the information management data 222 of the information management area 220 corresponding to the information 218 of the shared information area 216 of the intranet 42 (R56). Upon receiving this request, the information management unit 214 sets the information management data 222 in the information management area 220 to a non-updatable release state (F = 0) (R57).

  Then, the information synchronization unit 108 on the intranet 41 side requests the information management unit 114 to cancel the non-updating of the information management data 122 in the information management area 120 corresponding to the information 118 in the shared information area 116. (R58). In response to this request, the information management unit 114 cancels the non-updatable (F = 1) information management data 122 in the information management area 120 and enters an updatable state (F = 0) (R59).

  Next, the processing sequence of the above-described information processing will be described with reference to FIGS. 10 and 11 show an example of a processing sequence between intranets.

  When an information update request is given to the information display / update unit 106 of the intranet 41, an update request is notified from the information display / update unit 106 to the information management unit 114. When the information management unit 114 receives the update request, the update is performed. Impossibility determination processing (step S41) is performed, and when update is possible, update impossibility is set (step S42). In this case, when there is an intranet other than the intranets 41 and 42, it is determined that all the intranets cannot be updated (step S51), and the determination result indicating that updating is not possible is sent from the information management unit 114 to the information synchronization unit 108. Be notified. Such determination processing and notification of determination results are repeated for all intranets, and a setting request that cannot be updated is notified from the information synchronization unit 108 to the mail generation unit 110. In the mail generation unit 110, an e-mail representing a notification of a setting request that cannot be updated is created, and the mail transmission / reception unit 126 is requested to send an e-mail. In this case, a setting request that cannot be updated is sent from the intranet 41 to the intranet 42 (FIG. 11) by mail transmission.

  The electronic mail is received by the mail transmission / reception unit 226 of the intranet 42 through the Internet 6, and a mail analysis request is issued from the mail transmission / reception unit 226 to the mail analysis unit 212. The content of the mail analyzed by the mail analysis unit 212 is notified to the information synchronization unit 208, and a request for setting non-updatable is notified from the information synchronization unit 208 to the information management unit 214. In the information management unit 214, an unupdatable setting process (step S61) is performed, and after the setting process, the non-updatable setting completion notification is notified to the information synchronization unit 208. In response to this notification, a mail generation request is issued from the information synchronization unit 208 to the mail generation unit 210, and an e-mail representing a setting completion notification that cannot be updated is generated by the mail generation unit 210. A mail transmission request is notified from the mail generation unit 210 to the mail transmission / reception unit 226, and the mail transmission is transmitted to the intranet 41 (FIG. 10).

  The electronic mail is received by the mail transmission / reception unit 126 of the intranet 41 through the Internet 6, and a mail analysis request is issued from the mail transmission / reception unit 126 to the mail analysis unit 112. The mail content analyzed by the mail analysis unit 112 is notified to the information synchronization unit 108. That is, when the information synchronization unit 108 is notified of the completion of the non-updatable setting, it is determined whether or not all intranets are updatable (step S52), and this process is performed for all intranets. Repeat (step S53).

  When an information update request is notified from the information synchronization unit 108 to the mail generation unit 110, this notification is received, and a mail transmission request is notified from the mail generation unit 110 to the mail transmission / reception unit 126. This is notified to the intranet 42 (FIG. 11).

  The electronic mail is received by the mail transmission / reception unit 226 of the intranet 42 through the Internet 6, and a mail analysis request is issued from the mail transmission / reception unit 226 to the mail analysis unit 212. The mail contents analyzed by the mail analysis unit 212 are notified to the information synchronization unit 208, a request for information update is notified from the information synchronization unit 208 to the information management unit 214, and the information management unit 214 updates the information (step S62). Is executed. After executing the update process, the information management unit 214 cancels the non-updating (step S63), the information management unit 214 issues an update completion notification to the information synchronization unit 208, and the information synchronization unit 208 notifies the mail generation unit 210. A mail generation request is issued. An e-mail representing an update completion notification is created by the mail generation unit 210, a mail transmission request is notified from the mail generation unit 210 to the mail transmission / reception unit 226, and the mail transmission is performed to the intranet 41 (FIG. 10).

  After receiving the mail analysis request from the mail transmitting / receiving unit 126 and the notification of the analysis result of the mail analyzing unit 112, the information synchronization unit 108 executes a determination process (step S54) as to whether or not the information update has been completed on all intranets. The process is repeated for all intranets (step S55). When the update is completed, the information management unit 114 executes the information update process (step S43) on the intranet 41, and then cancels the non-update (step S44) and completes the information display / update. Section 106 is notified of the completion of the update.

  Next, regarding the above-described information processing, a processing sequence when a communication failure occurs will be described with reference to FIGS. 12 and 13 show an example of a processing sequence between intranets.

  As described with reference to FIG. 10 and FIG. 11, in response to the information update request from the intranet 41, the non-updatable setting is normally performed on the intranet 42 side, and the non-updatable setting completion notification is sent from the intranet 42 side. Even if it is received, there is an intranet n that shares information other than the intranet 42, and an e-mail from the intranet n is received, the analysis result is poor, and all intranets are updated. When it is not possible (NG) (step S52), the information update is canceled. This process is repeated for the transmitted intranet (step S55). In response to this, the information management unit 114 also cancels the previously set update impossibility (step S45), sets the update failure (NG), and displays the update failure (NG) on the information display / update unit 106. Notice.

  Then, the intranet 42 side is notified of the request for canceling the non-updating information, and the intranet 42 side receives the mail transmission, and determines whether or not the non-updatable setting has been made in the information management unit 214 (step S64). If the non-updatable is set, the non-updatable is canceled (step S65), and the communication failure (NG) process is terminated.

  By such processing, inconsistency of the information 118 and 218 between the intranets 41 and 42 due to forced update of information at the time of communication failure (NG) is prevented, and the reliability of the information 118 and 218 is maintained.

  Next, regarding the information processing described above, a processing sequence in the case where a time restriction is added to the information update processing will be described with reference to FIGS. 14 and 15. 14 and 15 show an example of a processing sequence between intranets.

  An information update request is generated from the intranet 41, and after the setting of non-updating, the setting of non-updatable on the intranet 42 is also completed, and the same processing is executed for all intranets. It is determined whether or not the predetermined time has elapsed since the standby time has become longer (step S56), and if the non-updatable setting is not completed even after the intranet n has elapsed the predetermined time, the update process is stopped as a timeout. . In this case as well, the intranet 42 is requested to release the non-updatable state, and the non-updatable state set in the information management data 122 set by the information management unit 114 is released together with the non-updatable release in the intranet 42.

  By setting a time limit (timeout) for such an update process, it is possible to prevent a delay in the update process of information on the intranets 41, 42, etc., and to execute information processing quickly.

  Next, with regard to the above-described information processing, a processing sequence when information update processing competes will be described with reference to FIGS. 16 and 17. FIG. 16 and FIG. 17 show an example of a processing sequence when update processing between intranets competes.

  An update request is generated before and after the intranet 41 (FIG. 16) and the intranet 42 (FIG. 17), and the update is determined after the determination that the update is impossible (step S41) and the setting that the update is disabled (step S42). In the case where the determination of improperness is repeated for all intranets and an unrenewable setting request is issued to the intranet 42, an update request is generated also on the intranet 42 side, and after the determination of unrenewable (step S71), setting of unrenewable Assuming that the processing of (Step S72) is performed by the information management unit 214, if the processing on the intranet 42 side is ahead in time, the update on the intranet 42 side is performed in response to the non-updatable setting request on the intranet 41 side. Even if the setting is disabled, a notification indicating that the setting cannot be updated is not received from the intranet 42. It is notified to the 1 side.

  In this case, a request for canceling the setting that cannot be updated is issued from the information synchronization unit 108 on the intranet 41 side, and this notification is notified to the intranet 42 by electronic mail. The notification of the e-mail notifies the intranet 42 side of a request for canceling the setting that cannot be updated, and cancels the setting that cannot be updated, but the update process on the intranet 42 side precedes. As a result, the update request on the intranet 41 side is not accepted. That is, for example, when an update request is generated between the intranets 41 and 42, an update process on the intranet side in which such a setting that cannot be updated is established, and the update request competes between the intranets. Information inconsistencies can be prevented, and inconveniences due to the complexity of information updating can be avoided.

  This is because, in a plurality of intranets including the intranets 41 and 42, when the cancellation of the non-updatable is received and the non-updatable is set, the intranet that requested the non-updatable cancellation is determined, and the non-updatable setting is set. If it is the same as the intranet you made, cancel the non-updatable release, and if it is from an intranet other than the intranet that was set non-updatable, avoid accepting the non-updatable release request and prevent the complexity of information updates can do.

  Next, a mechanism for avoiding conflict between information updates between intranets and a process thereof will be described with reference to FIG. 18, FIG. 19, and FIG. FIG. 18 is a diagram showing a processing sequence for avoiding information update competition in three sets of intranets, and FIGS. 19 and 20 are diagrams showing a processing sequence for avoiding information update competition in four sets of intranets. .

  In the processing illustrated in FIG. 18, it is assumed that information shared between the intranets 41, 42, and 43 is requested to update the information between the intranet 41 and the intranet 43. In this example, each of the intranet 41 and the intranet 43 requests the intranet 42 to make a non-updatable setting. When the intranet 42 first receives a non-updatable setting request from the intranet 41, the intranet 42 Update not possible is set, and an update request from another intranet, that is, an update impossible setting request from the intranet 43 is rejected. In response to the non-updatable setting request from the intranet 43, a non-updatable notification is returned to the intranet 43 as a notification that the non-updatable cannot be set in the intranet 42. When the intranet 43 receives a non-updatable non-updatable notification, it cancels the non-updatable setting, cancels the non-updatable setting for the information on the intranet 43, and notifies the user who made the update request an update NG Then, the update process from the intranet 43 side is completed.

  In this case, the intranet 41 receives a setting completion notification indicating that updating is not possible from the intranet 42, continues the information updating process, and implements the updating process.

  Further, in the process shown in FIG. 19, it is a competition in the intranets 41, 42, 43, 44. This is a case where there is an update request to the intranet 41 and the intranet 44, the intranet 41 makes a non-updatable setting request to the intranet 42, and the intranet 44 makes a non-updatable setting request to the intranet 43. . In this case, even if the intranet 41 makes a non-updatable setting to the intranet 42 and makes a non-updatable setting request to the intranet 43, the intranet 44 has already been set to non-updatable. In response to a setting request that cannot be updated, a notification that setting is rejected is returned. As a result, in the intranet 41, the update release processing is started, and in the intranet 41, the update is rejected as an update rejection.

  In this case, since the non-updatable setting request from the intranet 44 to the intranet 42 is rejected in the same manner as the request from the intranet 41 to the intranet 43, the updating process is also avoided for the intranet 44.

  The process shown in FIG. 20 is a case where there is a conflict between the Internets 41, 42, 43, and 44. The difference from the process shown in FIG. 19 is that the setting cancellation of the non-updatable setting from the intranet 41 to the intranet 42 is the intranet. It is completed before the setting request from 44 for non-updatable. In this case, the update from the intranet 41 is rejected (update NG), but since the update from the intranet 44 has no conflict between intranets, the update process is continued.

  As is clear from the process of avoiding these update conflicts, the information update conflict between intranets can be prevented by performing the non-updatable setting prior to the update process. The user who has received the update NG can once terminate the application, re-attack from taking in the information again, and update the information. And setting the non-updatable setting prior to the update can detect in advance a communication failure or the like that occurs via the Internet 6, so it is possible to check in advance the communication state between the intranet sharing information, When communication with all intranets sharing information is not possible, information is not updated, and inconsistency of shared information due to communication failure can be avoided.

  Next, technical matters are extracted from the embodiments of the information processing apparatus, the information processing method, and the information processing program described above, and the technical significance, modified examples, and other technical extension items are described below. Enumerate.

  (1) As described above, in the information processing system 2, when there is an update request for information shared by information processing apparatuses in a plurality of intranets connected by a network, the information synchronization unit on the intranet side that receives the request is: When the information management data corresponding to the information shared between the intranets is read and it is determined that the non-updatable setting is not set from the intranet, the non-updatable setting is requested for the information management data corresponding to the shared information. The shared information update process is performed at the stage where the information management data update disabled setting has been completed for all the information processing apparatuses in the intranet sharing the information. Thereby, it is possible to prevent the update processing of the shared information of the information processing apparatuses of a plurality of intranets from being performed individually and simultaneously on each intranet.

  (2) In the information processing system 2, regarding the information update for the shared information of the intranet, the information is updated from the information synchronization unit on the side of the intranet that has received the request after the setting of the non-updatable setting for the intranet is completed. At this time, the information synchronization unit performs an update process of information shared between the intranets, and returns to the update request side intranet that the update of the shared information has been completed. The completion of the information update can be confirmed by receiving the reply notification by the information synchronization unit of the intranet on the update request side. In addition, it is possible to monitor whether the shared information update process in the intranet has been performed normally.

  (3) The information processing system 2 uses an e-mail as a communication medium for a setting request for non-updating shared information between intranets, a request for updating shared information, and transmission / reception of update information. For this reason, shared information can be sent and received between intranets with limited access, especially between intranets of organizations with different security policies, without being aware of security regulations and without having to spend time on procedures. .

  (4) The information processing system 2 includes a shared information area for storing information shared by the intranet inside the intranet for sharing information, and information for storing information management data of information shared between intranets By providing the management area, even if information shared between intranets is being updated, it is possible to easily check whether the information is being updated by determining information management data in the information management area.

  (5) In the information processing system 2, when a request is made to an intranet that shares information, the mail generation unit creates an outgoing mail, and when an e-mail is received from an intranet that shares information, Since the analysis unit analyzes the contents of the received mail, the information synchronization unit can simplify the transmission / reception process, and the problem that the response time of requests from a plurality of intranets sharing information is delayed is solved.

  (6) In the above embodiment, the information is a document, but all files including data other than the document are equivalent.

  (7) In the above embodiment, the information display / update unit is document editing software in the PC. However, any information can be used as long as the file can be edited by a server in the intranet.

  (8) In the above embodiment, the information synchronization unit, the mail generation unit, and the mail analysis unit are in the information synchronization server. However, they may be distributed to a plurality of servers in the intranet.

  (9) Although the information management unit, shared information area, and information management area are located on the file server, they may be located on the information synchronization server, and the shared information area and information management area are distributed to different servers in the intranet. You may do it.

  (10) The information display / update unit may be installed outside the intranet.

  (11) The information synchronizer sends the requests for the shared intranet in parallel and receives them in parallel.However, the forwarding route for setting the shared information is set in advance, and between the other intranets according to the forwarding order. It can be carried around.

  (12) Regarding an intranet where shared information exists, this intranet may exist for each piece of information. Regarding shared information, a form in which data indicating an intranet is included in a part of information management data corresponding to the shared information may be used.

  (13) In the above embodiment, the information management units 114 and 214 execute the non-updatable determination process. However, the information synchronization units 108 and 208 may perform the determination process.

  Next, technical ideas extracted from the embodiments of the information processing apparatus, the information processing method, and the information processing program according to the present invention described above are listed as appendices according to the description format of the claims. The technical idea according to the present invention can be grasped by various levels and variations from a superordinate concept to a subordinate concept, and the present invention is not limited to the following supplementary notes.
