In software development using the VP tool, a series of processes is described as a flow by setting information corresponding to the purpose, environment, and other situations as property values in nodes where various processes are expressed, and connecting the nodes with lines. . A node corresponds to a function or method in a general procedural programming language. The user can intuitively develop software that performs intended processing by using the VP tool. One example of a VP tool is Node-RED. A series of flows developed with Node-RED are managed with code in JSON (JavaScript Object Notation) format based on JavaScript (registered trademark). Also, as an example of another VP tool, there is Apache Nifi and the like.

12 is an example of AP execution device information 451 . The exemplified AP execution device information 451 is described in JSON format data. The AP execution device information 451 includes communication-related information, the aforementioned attribute information, and authentication information.

Among them, the communication-related information is associated with each AP execution device 10 (AP process 800) when AP software processing is performed in association with each other AP execution device 10 (AP process 800) belonging to the same cluster. It is information necessary for inter-communication (for example, the IP address of the AP execution device 10, the port number of the AP process 800, etc.). In the same figure, the information described in the "0002" line corresponds to communication-related information.

Attribute information is information necessary for specifying the transfer destination AP execution device 10 when the AP process performs the above-mentioned "transfer processing". For example, the base 8 where the AP execution device 10 is installed. ), information specifying an organization that manages the AP execution device 10, the name of the AP execution device 10, information indicating the configuration (processor or memory information) of the AP execution device 10, and the like. Also, when the AP execution device 10 provides a virtual machine, the attribute information includes information about the virtual machine. In the same figure, information described in lines "0003" to "0019" corresponds to attribute information.

Further, the authentication information is information (user ID, password) required when accessing (communicating, using, etc.) the AP process 800 of the AP execution device 10 or functions realized by the AP process 800, and the like. In the same figure, information described in lines "0020" to "0021" corresponds to authentication information.

Fig. 13 shows the processing performed when the cluster management device 4 receives the AP execution device information from the client device 2 (hereinafter referred to as "AP execution device information reception sequence S1300") in S1112 of FIG. 11. It is an explanatory sequence diagram.

First, the processing request receiving unit 410 receives AP execution device information from the client device 2 (S1311), transmits the received AP execution device information to the cluster management unit 420, and the cluster management unit 420 (AP execution device) The device information management unit 421 and the inter-process information sharing unit 423 receive AP execution device information (S1312).

The AP execution device information management unit 421 of the cluster management unit 420 stores the received AP execution device information as the AP execution device information 451 (S1313). In addition, the inter-process information sharing unit 423 of the cluster management unit 420 stores the received AP execution device information 451 as a management target (S1314).

As another processing sequence, after the AP execution device information is registered (S1313), the AP execution device information management unit 421 transmits the AP execution device information to the inter-process information sharing unit 423 (S1312), and The information sharing unit 423 may store the AP execution device information 451 (S1314).

Fig. 14 is a sequence diagram illustrating processing (hereinafter referred to as "attribute information change sequence S1400") performed when the cluster management device 4 receives an attribute information change request from the client device 2.

First, the processing request acceptance unit 410 receives change information of attribute information from the client device 2 (S1411), transmits the received change information to the cluster management unit 420, and the cluster management unit 420 (AP execution) The device information management unit 421 and the inter-process information sharing unit 423 receive the change information (S1412). Further, upon reception of the change information, the processing request receiving unit 410 checks the content of the change information (whether or not illegal characters are included in the change information, and the values of the AP execution device 10 included in the change information). It is also possible to check whether the identifiers are duplicated or not) so that the attribute information is not stored in the cluster management device 4 as an illegal content. In this way, the occurrence of trouble can be prevented in advance by the process request accepting unit 410 inspecting the contents of the change information.

Subsequently, the AP execution device information management unit 421 reflects the received change information to the AP execution device information 451 (S1413). Further, the inter-process information sharing unit 423 reflects the transmitted change information to the AP execution device information stored by itself (S1414). In addition, since the contents of the AP execution device information 451 and the contents of the AP execution device information stored in the inter-process information sharing unit 423 need to be synchronized, the change information is changed in S1413 to the AP execution device information. After confirming that the information has been reflected in step 451, it is preferable to reflect the contents of the AP execution device information stored in the inter-process information sharing unit 423 (S1414).

15 is an example of change information of attribute information. The exemplified change information is described as data in JSON format. The exemplified change information includes communication-related information (line "0002") and attribute information (lines "0003" to "0019"), but does not include authentication information. In addition, the reason why the change information includes communication-related information is that it is necessary to specify AP execution device information to which the change information is reflected.

Fig. 16 is a sequence diagram illustrating processing (hereinafter referred to as "attribute information provision sequence S1600") performed when the cluster management device 4 receives a request for acquiring attribute information from the client device 2. In addition, the user refers to the attribute information provided by the process in editing the AP software, for example.

First, the processing request acceptance unit 410 accepts a request for acquiring attribute information from the client device 2 (S1611). The acquisition request may specify attribute information of a specific AP execution device 10 or may specify a plurality of attribute information managed (stored) by the cluster management device 4 .

Upon receiving the acquisition request, the processing request acceptance unit 410 transmits, to the attribute information management unit 422 of the cluster management unit 420, a provision request for the attribute information specified in the acquisition request (S1612).

Upon receiving the provision request, the attribute information management unit 422 transmits the attribute information specified in the provision request to the processing request acceptance unit 410 (S1613).

Upon receiving attribute information from the attribute information management section 422, the processing request acceptance unit 410 transmits the received attribute information to the client device 2 (S1614).

Fig. 17 is a sequence diagram illustrating a process performed when the cluster management device 4 receives an instruction to create an AP process 800 from the client device 2 (hereinafter referred to as "AP software execution preparation sequence S1700"). am. The AP software execution preparation sequence S1700 is a preparation process for the AP execution device 10 to execute the AP software 7.

First, an instruction to create the AP process 800 is transmitted from the client device 2 to the process request receiving unit 410 of the cluster management device 4 (S1711).

Upon receiving the creation instruction, the process request accepting unit 410 sends the AP process creation instruction to a plurality of AP execution devices 10 that are scheduled to execute the AP process 800 that is the target of the creation instruction in conjunction with each other. (AP execution devices 10 belonging to the same cluster. In this example, it is assumed that three AP execution devices 10 (1) to (3) belong to the same cluster) (S1712).

Upon receiving the creation instruction (S1713), the process execution management unit 120 of the AP execution device 10 creates the AP process 800 (S1713 and S1714).

The activated AP process 800 transmits an acquisition request for the AP software 7 to the inter-process information sharing unit 423 (S1715). Upon receiving the acquisition request, the inter-process information sharing unit 423 transmits the requested AP software 7 to the AP process 800, which is the source of the request, and the AP process 800 receives the AP software 7. and remember (S1716). Accordingly, the AP software 7 is deployed on the AP execution device 10 (AP process 800).

Subsequently, the AP process 800 transmits, to the inter-process information sharing unit 423, a participation registration request to the cluster (the cluster to which the AP execution device 10 that processes in association with the AP software 7 belongs) ( S1717). Upon receiving the participation registration request, the inter-process information sharing unit 423 updates the cluster management information 452 and registers the corresponding AP process 800 in the cluster (S1718).

Subsequently, the AP process 800 executes the information of the predetermined cluster (information (list information, etc.) of the AP process 800 belonging to the cluster, and the AP where the AP process 800 belonging to the cluster exists. Attribute information of the device 10, etc.) is transmitted to the inter-process information sharing unit 423 (S1719).

Upon receiving the provision request, the inter-process information sharing unit 423 acquires the information in question from the storage unit 405, and transmits the acquired information to the AP process 800 (S1720).

18 shows what happens when a new AP process 800 joins a cluster, which is performed when the AP execution device 10 belonging to the cluster (in this example, three AP execution devices 10 (1) to (3) belong It is a sequence diagram explaining a process related to information sharing between (hereinafter referred to as "intra-cluster information sharing sequence (at the time of AP process startup) S1800").

When the AP process 800 (1) is newly started in the AP execution device 10 (1) belonging to a certain cluster, the AP process 800 (1) transmits a participation registration request to the cluster as described above. Do (S1811).

Upon receiving the participation registration request, the inter-process information sharing unit 423 updates the cluster management information 452 and registers the corresponding AP process 800(1) in the cluster (S1812).

Subsequently, the inter-process information sharing unit 423 connects the AP execution device 10 where the AP process 800 (1) exists in the other AP execution devices 10, (2), and (3) belonging to the corresponding cluster. AP execution device information (including communication information, attribute information, and authentication information) of (1) is transmitted, and other AP execution devices 10, (2), and (3) receive the AP execution device information, Remember (S1813).

FIG. 19 shows the AP execution device 10 belonging to the cluster (in this example, three AP execution devices 10 (1) to (3) belonging to the cluster), which is performed when the AP process 800 disappears. It is a sequence diagram explaining the processing related to information sharing between (hereinafter, referred to as "intra-cluster information sharing sequence (when the AP process disappears) S1900"). In addition, as reasons for the disappearance of the AP process 800, there are, for example, a failure of the AP execution device 10 or the communication network 5, a user's intentional execution of the disappearance operation, and the like.

The inter-process information sharing unit 423 monitors the existence notification sent from the AP process 800 in real time (S1911). When the inter-process information sharing unit 423 detects that the existence notification of a certain AP process 800 (1) has been disconnected (S1912), it updates the cluster management information 452 so that the corresponding AP process 800 (1) Participation in the cluster to which the current AP process 800 (1) belongs is invalidated (S1913).

Subsequently, the inter-process information sharing unit 423 notifies the other AP processes 800 (2) and (3) belonging to the cluster that the AP process 800 (1) leaves the cluster (S1914). ). Upon receipt of the notification, the other AP processes 800 (2) and (3) update the information stored in them on the status of participation in the cluster, and the corresponding AP processes 800 (1) Participation in the cluster is invalidated (S1915).

In addition, by the above-described AP software execution preparation sequence S1700, intra-cluster information sharing sequence (when the AP process starts) S1800, and intra-cluster information sharing sequence (when the AP process disappears) S1900, the AP execution device belonging to the same cluster ( 10) Between (AP processes 800), synchronization of cluster-related information is always maintained.

Fig. 20 is a sequence diagram illustrating a flow of processing when the AP execution device 10 (AP process 800) executes the AP software 7 (hereinafter referred to as "AP software execution sequence S2000"). Also, in this example, the AP process 800 (1) of the AP execution device 10 (1) of the base (8) (1) and the AP execution device ( 10) It is assumed that the AP process 800 (2) of (2) cooperates to execute the AP software 7. In addition, the AP software 7 assumes the configuration illustrated in Fig. 21 as an example.

As shown in Fig. 20, first, the AP software processing execution unit 8121 (1) of the AP process 800 (1) receives an execution start instruction from the cluster management device 4 and executes the AP software 7. (Sequential execution from "Process A" starts) (S2011, S2012).

When the process reaches "transmission process a" through execution of "Process B" (S2013), the AP software processing execution unit 8121(1) sends the message transmission unit 8122 of the AP process 800(1) In (1), a message (hereinafter referred to as "transmission start message") containing information necessary for linking (handing over) the processing to the AP process 800 (2) is transmitted (S2014).

22 shows an example of a transmission start message. As shown in the figure, the transmission start message includes information specifying the destination AP execution device 10 (a description in the "0002" line, hereinafter referred to as "destination device designation information"), and "transfer processing a" identifier (description on the “0003” line, hereinafter referred to as “processing block ID”), information indicating the type (type) of the message (description on the “0004” line, hereinafter referred to as “transmission type”), and It includes information to be passed to the processing block of the linkage destination (transfer destination) (description of lines "0005" to "0007"; hereinafter referred to as "linkage information").

In this example, "edge_siteA" is described as destination device specification information. This specifies that the AP execution device 10 (2) existing in the base (8) (2) should be designated as the destination. Also, "start" is designated as the transmission type. This indicates that the message is a transmission start message. The linkage information is, for example, the learning model 30 (parameter) when the AP software 7 is what is illustrated in FIG. 3 .

Returning to Fig. 20, when the transmission start message is received, the message transmission unit 8122 (1) compares the destination device designation information of the transmission start message with AP execution device information 451 and cluster management information 452, and , An AP execution device 10 (2) having an attribute specified in the destination device designation information is selected as an associated AP execution device 10 (2) (S2015). Further, in the above selection, the message transmission unit 8122(1) provides information (example For example, the network address of the AP execution device 10 and the port number of the AP process 800 (2) of the AP execution device 10 (2) are acquired.

Subsequently, the message transmission unit 8122 (1) sends a message notifying the selected AP execution device 10 (2) (AP process 800 (2)) of linkage start (hereinafter referred to as "association start message"). ') is transmitted (S2016).

Fig. 23 shows an example of an association start message. As shown in the figure, the linkage start message includes information indicating the sender's AP execution device 10(1) (a description of the "0002" line, hereinafter referred to as "sender information") and "transfer processing a" Identifier (description on the “0003” line, hereinafter referred to as “processing block ID”), information indicating the type (type) of the message (description on the “0004” line, hereinafter referred to as “transmission type”), connection destination It includes information to be passed to the (transfer destination) processing block (description of lines "0005" to "0007"; hereinafter referred to as "linkage information"). In addition, the sender information is information required when the AP process 800 (2), which is a linkage destination, again transfers processing to the AP process 800 (1).

Returning to FIG. 20 , when the message transmission unit 8122 (2) of the AP process 800 (2) of the AP execution device 10 (2) of the association destination receives the association start message, the received association start message is notified (transmitted) to the AP software processing execution unit 8121 (2) of the AP process 800 (2) (S2017).

When the AP software processing execution unit 8121 (2) receives the linkage start message, it starts processing from "Process C" with the content of the "linkage information" of the linkage start message as an input (S2018, S2019). In addition, since the identifier of "transfer process a" is set in the "process block ID" of the linkage start message, the AP software processing execution unit 8121 (2) proceeds from "process C" following "transfer process a". Initiate processing.

When the process reaches the "transmission process b" through the execution of "Process D" (S2020), then the AP software processing execution unit 8121 (2) proceeds to the message transmission unit (of the AP process 800 (2)) 8122)(2) is notified (transmitted) of a message instructing linkage (handover) of processing to the AP process 800 (1) (hereinafter referred to as "transfer end message") (S2021).

Upon receiving the transmission end message, the message transmitter 8122 (2) sends a message (hereinafter referred to as “association end referred to as "message") is transmitted (S2022).

24 shows an example of an association termination message. As shown in the figure, the linkage end message includes information indicating the AP execution device 10(1) that is the sender of the linkage start message (a description of the "0002" line; hereinafter referred to as "sender information"), and "transfer Process a” (description on the “0003” line, hereinafter referred to as “process block ID”), information indicating the type (type) of the message (description on the “0004” line, hereinafter referred to as “transmission type”) ), and information to be passed to the processing block of the linkage destination (transfer destination) (description of lines "0005" to "0007"; hereinafter referred to as "linkage information"). Incidentally, the sender information in the linkage termination message is the same as the sender information in the linkage start message. Further, in the linkage information, for example, when the AP software 7 is the one illustrated in FIG. 3 , the learning model 30 (parameter) updated by the sensor data is set.

Returning to FIG. 20 , when the message transmission unit 8122 (1) of the AP process 800 (1) receives an association end message, the AP software processing execution unit 8121 (1) converts the content of the received association end message to the AP software processing unit 8121 (1). ) is notified (transmitted) (S2023). Upon receiving the above notification, the AP software processing execution unit 8121(1) specifies a processing block to be executed next based on the content of the linkage end message (specified as "process E" in this example), and terminates the linkage. The processing is started from a specific processing block ("Process E") by taking the "connection information" of the message as an input. Further, in the AP software processing execution unit 8121(1), the identifier of "transfer process a" is set in the "process block ID" of the linkage end message, and "end" meaning linkage end is set in the "transfer type". Since it is set, processing starts from "process E" following "transfer processing b".

As described above, processing is linked between the AP execution devices 10 (AP processes 800) of each base 8 through "transfer processing", and the AP execution device 10 of each base 8 Processing is executed by the same (common) AP software 7 that is deployed.

As described above in detail, in the information processing system 1 of the present embodiment, AP software 7 having a common (same) configuration is provided in each of a plurality of AP execution devices 10 that execute processing in association with each other. is provided (deployed), there is no need to build different AP software 7 for each AP execution device 10, and the information processing system 1 provides software that executes processing in cooperation between a plurality of bases 8. can be developed effectively. In addition, since the user can designate the AP execution device 10 that executes the AP software 7 in the AP execution device information 451 that can be set, the user can easily and flexibly set the execution environment of the AP software 7. You can choose.

In addition, since the common (same) AP software 7 is provided (deployed) to any of the plurality of AP execution devices 10, the burden of management (maintenance) and operation of the AP software 7 is reduced. Moreover, the communication load of the information processing system 1 as a whole can be reduced, and security can be improved.

The DB connection confirmation execution unit 8123, at an appropriate timing, such as when the AP software 7 is deployed on the AP execution device 10, arrives at the base 8 where the AP process 800 including itself exists. , processing for confirming whether or not data corresponding to the data specifying information described in the AP software 7 is available (hereinafter referred to as DB connection confirmation sequence S3500) is performed.

35 is a sequence diagram illustrating an example of the DB connection confirmation sequence S3500. As shown in the figure, when the AP software 7 is deployed to the AP process 800 in the AP software execution preparation sequence S1700 in FIG. 17 (S1716), the DB connection confirmation execution unit 8123 stores the storage unit ( 105) is referred to the AP software 7 stored (S3501 to S3502), and the data specifying information described in the AP software 7 is read (S3503). Furthermore, the DB connection confirmation execution unit 8123 acquires the DB connection information 154 of the data corresponding to the read data designation information from the storage unit 105 (S3504 to S3505).

Subsequently, the DB connection confirmation execution unit 8123 accesses the database 2801 using the acquired DB connection information 154, and confirms whether access to the database 2801 is possible (for example, the ping command It is checked whether or not the database 2801 is reached) (S3506 to 3507).

Subsequently, the DB connection confirmation execution unit 8123 checks whether data corresponding to the data designation information of the access destination database 2801 is available (whether the value of the data can actually be obtained) (S3508 to 3509). When the data corresponding to the data designation information is available, the DB connection confirmation execution unit 8123 determines that the data is available in the AP process 800 including itself (that is, processing using the data (e.g., For example, processing described in lines 3206 to 3212 in Fig. 32) is notified to the inter-process information sharing unit 423 (S3510). On the other hand, when the data corresponding to the data designation information is not available, the DB connection confirmation execution unit 8123 determines that the data is not available for the AP process 800 including itself (that is, the data is not available). that the processing to be used cannot be executed) is notified to the inter-process information sharing unit 423 (S3510).

Upon receiving the above notification, the inter-process information sharing unit 423 updates the data list 453 and provides the contents of the updated data list 453 to each AP execution device 10 or cluster management device 4. do. Accordingly, the message transmission unit 8122 of the AP process 800, among other AP processes 800 (AP execution device 10) other than the AP process 800 including itself, sends the The AP process 800 (AP execution device 10) can know which data is available.

By the way, in the foregoing, the case where AP software 7 is deployed (S1716) triggers the AP execution device 10 to check whether or not the data in the database 2801 is actually available has been exemplified, but the above confirmation is , for example, when the contents of the database 2801 are updated (registering, editing, or deleting data) or when the database 2801 ceases to exist.

Fig. 36 is a sequence diagram explaining the AP software execution sequence S2000 in the third embodiment. The AP software execution sequence S2000 of the third embodiment differs from the AP software execution sequence S2000 of the first embodiment in the content of the transmission start message transmitted in S2014 and the processing content in S2015.

As shown in the same figure, when the execution of the processing described in the AP software 7 starts and the processing using the data of the base 8 (for example, the processing of lines 3206 to 3212 in FIG. 32) is reached, (S3601), as in the first embodiment, a transfer start message is transmitted from the AP software processing execution unit 8121 (1) to the message transfer unit 8122 (1) (S3602). However, unlike the first embodiment, in the transmitted transmission start message, there is not attribute information of the transfer destination base 3, but data specifying information (data name, etc.) specifying data to be used in the execution of the subsequent processing block. is described.

Subsequently, the message transmission unit 8122(1) selects the AP execution device 10 capable of using the data corresponding to the data designation information (S3603). This process is performed by the message transfer unit 8122(1) referring to the data list 453 provided from the inter-process information sharing unit 423 as described above. Each process of the subsequent AP software execution sequence S2000 is the same as that of the first embodiment.
