[First embodiment]
FIG. 1 shows a schematic configuration of an information processing system 1 described as the first embodiment. As shown in the figure, the information processing system 1 includes a client device 2, an AP management device 3, a cluster management device 4, and one or more AP executing devices existing in each of a plurality of bases 8(1) to (N). It includes device 10 . All of these devices are configured using information processing devices (computers) and are connected to each other via a communication network 5 so as to be able to communicate with each other.

The communication network 5 is a communication infrastructure (Network Infrastructure) that realizes communication according to a predetermined communication protocol such as Ethernet (registered trademark) or TCP/IP. ), the Internet, leased lines, public communication networks, etc.

The client device 2 provides users such as software development engineers and domain experts with an environment for editing and generating application software (hereinafter referred to as “AP software”) executed by the AP execution device 10 (hereinafter referred to as “software development environment”). ). In this embodiment, as an example, the client device 2 provides a software development environment using a visual programming tool (hereinafter abbreviated as "VP tool"). Not necessarily limited.

In software development using VP tools, nodes that express various processes include:
A series of processes is described as a flow by setting information corresponding to usage, environment, and other situations as property values and connecting nodes with lines. Nodes correspond to functions or methods in common procedural programming languages. By using the VP tool, the user can intuitively develop software that performs intended processing. An example of a VP tool is Node-RED. A series of flows developed by Node-RED are managed by code in JSON (JavaScript Object Notation) format based on JavaScript (registered trademark). Other examples of VP tools include Apache Nifi.

In FIG. 1, the AP management device 3 manages (stores) AP software generated by the client device 2 . For example, if the AP software is generated by Node-RED, the AP management device 3 manages the JSON format code of the AP software. The AP software may be managed by the AP management device 3 as a container (a package containing an execution module of the AP software, information about the execution environment, information about the deployment method and operation method, etc.). An example of a container is by Docker (registered trademark). The AP management device 3 may have a mechanism (such as GitHub (registered trademark) and GitLab (registered trademark)) for version management of AP software.

Sites 8 (1) to (N) are, for example, sites where cloud and sensor data are collected (factories, various work sites, distribution warehouses, offices, various facilities (elevators, automatic ticket gates, various gates, railway facilities , road equipment, environmental measurement equipment using sensors, mobile objects (automobiles, trains, aircraft, drones, agricultural equipment, etc.), farms, data centers, etc.

The cluster management device 4 provides (manages, monitors, and controls) execution control and monitoring of processing in the AP execution devices 10 and cluster services (load distribution, failover, etc.) using a plurality of AP execution devices 10 . In this specification, a cluster refers to a set of AP execution devices 10 that can work together to execute AP software processing. The cluster management device 4 also manages one or more clusters and, for example, performs processing related to registration (participation) of the AP execution device 10 in the cluster and deregistration. The cluster management device 4 also distributes information (AP software, AP execution device information, which will be described later, etc.) to the AP execution devices 10 and information between the AP execution devices 10 (information of the AP execution devices 10 participating in the cluster ( A list of participating AP execution devices 10, AP execution device information (to be described later), etc.)) are shared. The cluster management device 4 implements a cluster service not only between the AP execution devices 10 within the same site 8 but also between the AP execution devices 10 beyond the site 8 .

One or more AP executing devices 10 exist at each of the bases 8(1)-(N). The AP execution device 10 present at each site 8(1) to (N) can execute AP software in cooperation with other AP execution devices 10 at the same or different sites 8 belonging to the same cluster.

FIG. 2 is a diagram showing a schematic flow from when the AP software generated by the client device 2 is provided (deployed) to the AP executing devices 10 until each AP executing device 10 executes the AP software.

As shown in the figure, the AP software 7 generated by the client device 2 is registered in the AP management device 3 and provided (transmitted) to the cluster management device 4 (S21). The illustrated AP software 7 has five processing blocks (“processing A”, “processing B”, “transfer processing”, “processing C”, and “processing D”) that are sequentially executed. Each processing block corresponds, for example, to one processing block in a VP tool, or to a function or method in common procedural programming languages. The processing block may call and use other software that already exists in the AP execution device 10 (for example, software provided as an API (Application Program Interface)). "Processing A" and "Processing B" are processing blocks scheduled to be executed at site 8(1), and "Processing C" and "Processing D" are executed at site 8(2). is a scheduled processing block.

Subsequently, the cluster management device 4 deploys the AP software 7 having a common (same) configuration to the plurality of AP execution devices 10 belonging to the same cluster (S22). In this example, the cluster management device 4 manages the AP execution device 10(1) of the site 8(1) and the AP execution device 10(2) of the site 8(2) as the AP execution devices 10 belonging to the common cluster. , the common AP software 7 is deployed to the AP executing device 10(1) of the base 8(1) and the AP executing device 10(2) of the base 8(2).

The processing of the AP software deployed on the AP execution device 10 is started by, for example, the cluster management device 4 sending an execution start instruction for the AP software 7 to one of the AP execution devices 10(1). In this example, the cluster management device 4 sends an execution start instruction to the AP execution device 10(1) of the base 8(1), and the AP execution device 10(1) starts execution of the AP software (from "process A" to execution start).

When the "process A" ends, the AP executing device 10(1) subsequently executes the "process B" and then executes the "transfer process". The “transfer process” is a process of linking (handing over) the process to another AP execution device 10 . In this example, the processing is coordinated with the AP executing device 10(2) of the site 8(2), and the processing result of the "processing B" is handed over to the "transfer processing" of the AP executing device 10(2) to execute the AP. The "transfer process" of the device 10(2) starts from the subsequent "process C".

A specific example of the AP software 7 is shown in FIG. The AP software 7 illustrated as an example is software that realizes a predictive diagnosis function using a machine learning model (hereinafter referred to as a "learning model") by edge computing.

As shown in the figure, the AP execution device 10(1) of the site 8(1), which is a cloud, is used by the AP execution device 10(2) of the site 8(2), which is an edge, for predictive diagnosis. manages (stores) the learning model 30 of

First, the AP execution device 10(1) acquires a learning model to be provided to the AP execution device 10(2) of the site 8(2), which is an edge (S31), and the acquired learning model is transferred to the AP of the site 8(2). It is transferred to the execution device 10 (S32). The process of S32 corresponds to the "transfer process" described above.

The AP executing device 10(2) of the site 8(2) receives and stores the learning model (S33). Subsequently, the AP executing device 10 (2) acquires sensor data (S34), applies the acquired sensor data to the stored learning model, performs predictive diagnosis (S35), and performs predictive diagnosis according to the result of the predictive diagnosis. Processing (such as outputting an alert) is performed (S36).

On the other hand, the AP execution device 10(2) updates the learning model by performing machine learning using the acquired sensor data as learning data (S37), and updates the updated learning model to the AP execution device 10 of the site 8(1). (1) (S38). S33 and S38 correspond to the "transfer process" described above.

The cloud AP execution device 10(1) receives the learning model (S39), and updates the learning model 30 managed (stored) to the contents of the received learning model (S40). The process of S39 corresponds to the "transfer process" described above.

As described above, the AP software 7 having a common (same) configuration is provided (deployed) to each of the plurality of AP execution devices 10 that cooperate to execute processing. Therefore, the AP executing device 10
There is no need to build different AP software 7 for each, and the AP software 7 can be built by a specific developer who is familiar with processing between the cloud and the base 8, for example. Therefore, the domain experts of each site 8 do not need to construct the AP software 7 individually, and the software that executes processing in cooperation with the multiple sites 8 can be efficiently developed as the entire information processing system 1 .

In addition, common (same) AP software 7 is provided (deployed) to any of the plurality of AP execution devices 10 . Therefore, the management (maintenance) burden and operation burden of the AP software 7 can be reduced. In principle, communication between AP execution devices 10 occurs only during transfer processing, so the communication load on the entire information processing system 1 can be reduced. security can be improved.

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

First, the processing request reception unit 410 receives the 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 information management unit 421 , inter-process information sharing unit 423) receives the 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). Also, 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 order, 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 inter-process information The sharing unit 423 may store the AP execution device information 451 (S1314).

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

First, the processing request reception unit 410 receives attribute information change 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 executing device information management unit 421 , inter-process information sharing unit 423) receives the change information (S1412). When accepting the change information, the processing request reception unit 410 checks the content of the change information (whether the change information contains illegal characters or not, and the identifier of the AP execution device 10 included in the change information is checked). check for duplication, etc.) to prevent the attribute information from being stored in the cluster management device 4 with incorrect content. By having the processing request receiving unit 410 inspect the contents of the change information in this way, it is possible to prevent troubles from occurring.

Subsequently, the AP execution device information management unit 421 reflects the received change information in the AP execution device information 451 (S1413). Also, the inter-process information sharing unit 423 reflects the sent change information in the AP execution device information stored therein (S1414). Since the content of the AP execution device information 451 and the content of the AP execution device information stored in the inter-process information sharing unit 423 need to be synchronized, the change information is changed to the AP execution device information 451 in S1413. After it is confirmed that the information has been reflected in the AP executing device information stored in the inter-process information sharing unit 423 (S1414).

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

FIG. 16 is a sequence diagram for explaining the processing (hereinafter referred to as "attribute information provision sequence S1600") performed when the cluster management device 4 receives an attribute information acquisition request from the client device 2. As shown in FIG. It should be noted that the user refers to the attribute information provided by the process when editing the AP software, for example.

First, the processing request reception unit 410 receives an attribute information acquisition request from the client device 2 (S1611). The acquisition request may specify attribute information of a specific AP executing 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 reception unit 410 transmits a request for provision of the attribute information specified in the acquisition request to the attribute information management unit 422 of the cluster management unit 420 (S1612).

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

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

FIG. 17 is a sequence diagram for explaining the processing (hereinafter referred to as "AP software execution preparation sequence S1700") performed by the cluster management device 4 when receiving an instruction to generate the AP process 800 from the client device 2. As shown in FIG. The AP software execution preparation sequence S1700 is a preparation process for the AP executing device 10 to execute the AP software 7. FIG.

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

Upon receiving the generation instruction, the processing request reception unit 410 sends the AP process generation instruction to a plurality of AP execution devices 10 (same cluster) scheduled to cooperate and execute the AP process 800 targeted by the generation instruction. (S1712).

Upon receiving the generation instruction (S1713), the process execution management unit 120 of the AP execution device 10 generates the AP process 800 (S1713, 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 requesting AP process 800, and the AP process 800 receives and stores the AP software 7 (S1716). As a result, the AP software 7 is deployed to the AP execution device 10 (AP process 800).

Subsequently, the AP process 800 transmits a participation registration request to the cluster (the cluster to which the AP execution device 10 processing in cooperation with the AP software 7 belongs) to the inter-process information sharing unit 423 (S1717). When the inter-process information sharing unit 423 receives the participation registration request, it updates the cluster management information 452 and registers the AP process 800 in the cluster (S1718).

Subsequently, the AP process 800 obtains the information of the predetermined cluster (information of the AP processes 800 belonging to the cluster (list information, etc.), the attributes of the AP execution devices 10 in which the AP processes 800 belonging to the cluster exist, information, etc.) to the inter-process information sharing unit 423 (S1719).

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

FIG. 18 shows the process performed when a new AP process 800 joins the cluster, which is performed by the AP executing devices 10 belonging to the cluster (in this example, three AP executing devices 10 (1) to (3) belong to the cluster). 18 is a sequence diagram for explaining a process (hereinafter referred to as "intra-cluster information sharing sequence (when AP process is activated) S1800") regarding information sharing between AP processes.

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

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

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

FIG. 19 shows the process performed when the AP process 800 disappears, the AP executing apparatuses 10 belonging to the cluster (in this example, three AP executing apparatuses 10 (1) to (3) belong to the cluster). FIG. 10 is a sequence diagram for explaining processing related to information sharing between clusters (hereinafter referred to as “intra-cluster information sharing sequence (when AP process disappears) S1900”); Reasons for the disappearance of the AP process 800 include, for example, a failure of the AP execution device 10 and the communication network 5, and an intentional disappearance operation by the user.

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

Subsequently, the inter-process information sharing unit 423 notifies the other AP processes 800(2) and 800(3) belonging to the cluster that the AP process 800(1) has left the cluster (S1914). When the other AP processes 800(2) and (3) receive the above notification, they update their stored information about the participation status of the cluster, and request the AP process 800(1) to participate in the cluster. Participation is invalidated (S1915).

By the AP software execution preparation sequence S1700, the intra-cluster information sharing sequence (when the AP process starts) S1800, and the intra-cluster information sharing sequence (when the AP process disappears) S1900 described above, the AP executing devices 10 belonging to the same cluster Between (AP processes 800), information about the clusters is kept synchronized at all times.

FIG. 20 is a sequence diagram for explaining the 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"). In this example, the AP process 800(1) of the AP execution device 10(1) of the site 8(1) and the AP process 800(2) of the AP execution device 10(2) of the site 8(2) belong to the same cluster. 2) are assumed to execute the AP software 7 in cooperation with each other. It is also assumed that the AP software 7 has the configuration illustrated in FIG. 21 as an example.

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

When the process reaches "transfer process a" after executing "process B" (S2013), AP software process execution unit 8121(1) sends message transfer unit 8122(1) of AP process 800(1) an AP A message (hereinafter referred to as a “transfer start message”) including information necessary for linking (handing over) processing to the process 800(2) is transmitted (S2014).

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

In this example, "edge_siteA" is described as the destination device designation information. This specifies that the AP execution device 10(2) existing at the site 8(2) should be specified as the destination. Also, "start" is specified as the transfer type. This indicates that the message is a transfer start message. The cooperation information is, for example, the learning model 30 (parameter) when the AP software 7 is the one illustrated in FIG.

Returning to FIG. 20, upon receiving the transfer start message, the message transfer unit 8122(1) compares the destination device designation information of the transfer start message with the AP execution device information 451 and the cluster management information 452, and determines the destination device designation information. selects the AP execution device 10(2) having the attribute designated by as the AP execution device 10(2) of the cooperation destination (S2015). It should be noted that, upon selection, the message transfer unit 8122(1) uses information (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).

Subsequently, the message transfer unit 8122(1) sends a message for notifying the start of cooperation (hereinafter referred to as a “cooperation start message”) to the selected AP execution device 10(2) (AP process 800(2)). Send (S2016).

FIG. 23 shows an example of a cooperation start message. As shown in the figure, the cooperation start message includes information indicating the source AP execution device 10(1) (description in line "0002"; hereinafter referred to as "source information"), "transfer processing a ” (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 “transfer type”). ), and information (description of lines “0005” to “0007”; hereinafter referred to as “cooperation information”) to be passed to the processing block of the cooperation destination (handover destination). The transmission source information is information required when the AP process 800(2), which is the cooperation destination, takes over the processing to the AP process 800(1) again.

Returning to FIG. 20, upon receiving the cooperation start message, the message transfer unit 8122(2) of the AP process 800(2) of the cooperation destination AP execution device 10(2) forwards the received cooperation start message to the AP process 800(2). 2) is notified (transmitted) to the AP software processing execution unit 8121 (2) (S2017).

When the AP software process execution unit 8121(2) receives the cooperation start message, it receives the contents of the "cooperation information" of the cooperation start message and starts the process from "process C" (S2018, S2019). Note that the AP software process execution unit 8121 (2), since the identifier of "transfer process a" is set in the "processing block ID" of the cooperation start message, executes "process C" following "transfer process a". Start processing from

When the process reaches "transfer process b" after executing "process D" (S2020), then AP software process execution unit 8121(2) sends message transfer unit 8122(2) of AP process 800(2) to , the AP process 800(1) notifies (transmits) a message (hereinafter referred to as a "transfer end message") instructing the cooperation (handover) of processing to the AP process 800(1) (S2021).

Upon receiving the transfer end message, the message transfer unit 8122(2) sends a message to notify the AP process 800(1) of the AP execution device 10(1) of the end of cooperation (hereafter referred to as a "cooperation end message"). is transmitted (S2022).

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

Returning to FIG. 20, when the message transfer unit 8122(1) of the AP process 800(1) receives the cooperation end message, it notifies (transmits) the contents of the received cooperation end message to the AP software processing execution unit 8121(1). (S2023). Upon receipt of the notification, the AP software process execution unit 8121(1) identifies a processing block to be executed next based on the content of the cooperation end message (in this example, "process E"), and executes the cooperation end message. The processing is started from the specified processing block (“Processing E”) with the “linkage information” as an input. Note that the AP software processing execution unit 8121(1) sets the identifier of "transfer process a" in the "processing block ID" of the cooperation end message, and sets "end", which means the end of cooperation, in the "transfer type". Therefore, the process starts from "process E" following "transfer process b".

As described above, processing is coordinated between the AP execution devices 10 (AP processes 800) at each site 8 via the "transfer process", and the same (common) deployed to the AP execution devices 10 at each site 8 ) The processing is executed by the AP software 7 .

As described above in detail, in the information processing system 1 of the present embodiment, the AP software 7 having a common (same) configuration is provided to each of the plurality of AP execution devices 10 that cooperate to execute processing. Since it is (deployed), there is no need to construct different AP software 7 for each AP execution device 10, and software for executing processing in cooperation with a plurality of bases 8 can be efficiently developed as an entire information processing system 1.例文帳に追加can be done. In addition, since the AP execution device 10 that executes the AP software 7 can be specified in the AP execution device information 451 that can be set by the user, the user can easily and flexibly select the execution environment of the AP software 7 .

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

A user (data manager or the like) of each site 8 can edit the data list 153 and the DB connection information 154 via the data information management unit 130 . The DB connection information 154 is managed individually in each AP execution device 10 from the viewpoint of preventing information leakage to the outside, and is not transmitted to the cluster management device 4 in principle. The data list 153 is also sent to the cluster management device 4 via the communication network 5 .

FIG. 30 shows main functions of the cluster management device 4 of the third embodiment. The storage unit 405 of the cluster management device 4 of the third embodiment stores a data list 453 in addition to the data stored by the storage unit 405 of the cluster management device 4 of the first embodiment. The data list 453 is data obtained by integrating the data lists 153 sent from the AP execution devices 10 of the bases 8 and managed by the inter-process information sharing unit 423 . As will be described later, whether or not the AP execution device 10 can actually access each data registered in the data list 453 is confirmed (verified) when the AP software 7 is deployed to the AP execution device 10 or the like. be.

Data designation information (data name in this example) is set in the data name 4532 . In the description 4533, information describing the data (information referred to by a person such as the developer of the AP software 7) is set. The data list 453 may further include items (columns) in which the format of each data and sample data are set. Also, the illustrated data list 453 is described in a relational database format, but the format of the data list 453 is not necessarily limited.

FIG. 32 shows a description example of the AP software 7 in the third embodiment. The exemplified AP software 7 is written according to the syntax of the Python language. Note that the language used to describe the AP software 7 is not necessarily limited. One processing block of the AP software 7 shown in FIG. 21 of the first embodiment corresponds to one function described in the AP software 7 exemplified in FIG. Five functions are described in the AP software 7 illustrated in FIG. Among them, the main function (lines 3223 to 3226) is executed first, and the other four functions are sequentially called from the main function and executed. As shown in the figure, in this example, only the anomaly_factor function (lines 3206 to 3212) is added with a decorator described using the "@" symbol. This decorator indicates that the Anomaly_factor function will be executed at the site 8 where the data corresponding to the data name (data designation information) "pic.line-a.jp" is managed. In the 3206th line, a plurality of data names (data designation information) can be described at the same time.

“db_connector.get(data[0])” on the 3209th line is a function for accessing data in the database 2801 . Data values are obtained from the database 2801 by executing the function. In line 3211, processing using the value acquired in line 3209 is performed. Note that the above functions are described in a general description format that does not depend on the type of database 2801 (hereinafter referred to as "DB type"). As a result, the developer of the AP software 7 can efficiently develop the AP software 7 without being conscious of the DB type.

An example of the DB connection information 154 is shown in FIG. The DB connection information 154 manages information (DB connection information) necessary for the AP execution device 10 to access the database 2801 . The illustrated DB connection information 154 is composed of one or more records including each item such as data name 1541, DB type 1542, connection destination 1543, authentication information 1544, and the like.

Connection information (IP address, port number, etc.) used when accessing the database 2801 is set in the connection destination 1543 . Authentication information (user ID, password, etc.) required for accessing the database 2801 is set in the authentication information 1544 .

The developer of the AP software 7 writes a general-purpose function such as the data acquisition function (db_connector.get) described in line 3209 in FIG. The access from the AP execution device 10 to the database 2801 is performed by the AP execution device 10 referring to the DB connection information 154 managed by the base 8 side. Therefore, the developer of the AP software 7 can develop the AP software 7 efficiently. Note that when describing processing for editing (registration, update, deletion, etc.) of data managed in the database 2801 in the AP software 7, it is possible to describe a general-purpose function similar to the data acquisition function exemplified. By doing so, the development efficiency of the AP software 7 can be improved.

As shown in the figure, when the AP software 7 is deployed into the AP process 800 in the AP software execution preparation sequence S1700 of FIG. The AP software 7 is referenced (S3501 and S3502), and the data designation information described in the AP software 7 is read (S3503). The DB connection confirmation executing unit 8123 also acquires the DB connection information 154 of the data corresponding to the read data designation information from the storage unit 105 (S3504 and S3505).

Subsequently, the DB connection confirmation executing unit 8123 accesses the database 2801 using the acquired DB connection information 154, and confirms whether or not the database 2801 is accessible (for example, whether or not the ping command reaches the database 2801). confirmation) (S3506-3507).

Subsequently, the DB connection confirmation executing unit 8123 confirms whether or not the data corresponding to the data designation information of the access destination database 2801 can be used (whether or not the value of the data can actually be acquired) (S3508 to 3509). If the data corresponding to the data designation information is available, the DB connection confirmation execution unit 8123 confirms that the data is available in the AP process 800 including itself (that is, processing using the data (for example, 32, lines 3206 to 3212) can be executed) to the inter-process information sharing unit 423 (S3510). On the other hand, if the data corresponding to the data designation information is not available, the DB connection confirmation execution unit 8123 cannot use the data in the AP process 800 including itself (that is, cannot execute processing using the data. ) to the inter-process information sharing unit 423 (S3510).

The inter-process information sharing unit 423 updates the data list 453 by receiving the above notification, and provides the contents of the updated data list 453 to each AP execution device 10 and the cluster management device 4 . As a result, the message transfer unit 8122 of the AP process 800 determines that the AP process 800 (AP execution device 10) of any site 8 among the other AP processes 800 (AP execution device 10) other than the AP process 800 including itself is Know what data is available.

By the way, in the above description, the deployment of the AP software 7 (S1716) is used as a trigger for the AP execution device 10 to check whether or not the data in the database 2801 can actually be used. , when the contents of the database 2801 are updated (data registration, editing, or deletion), or when the database 2801 no longer exists.

FIG. 36 is a sequence diagram illustrating the AP software execution sequence S2000 of 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 contents of the transfer start message transmitted in S2014 and the contents of the processing in S2015.

As shown in the figure, the execution of the processing described in the AP software 7 is started, and when 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, the transmitted transfer start message does not include attribute information of the transfer destination base 3, but data specification information (data name, etc.) that specifies data to be used when executing subsequent processing blocks. ) is described.

Subsequently, the message transfer unit 8122(1) selects an AP execution device 10 that can use 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 by the inter-process information sharing unit 423 as described above. Subsequent processing of the AP software execution sequence S2000 is the same as in the first embodiment.

FIG. 37 is an example of the transfer start message sent in S3602 of FIG. Unlike the first embodiment, the transfer start message illustrated does not include information indicating the attribute information of the site 8, but rather describes data designation information (data name) of data used in subsequent processing blocks (3702). ~ line 3704). It should be noted that the transfer start message can also describe a plurality of pieces of data specification information in a list format so that processing using a plurality of pieces of data can be handled.

As described above, according to the information processing system 1 of the third embodiment, the AP execution device 10 that can use the data designation information (data name, etc.) described in the AP software 7 automatically A cooperation start message is sent to the selected AP executing device 10 . Therefore, the developer does not need to know whether or not the AP execution device 10 of any site 8 can be linked, and can efficiently develop the AP software 7. Particularly, many sites 8 exist in a wide range. If you do, you can expect great results. In addition, the developer of the AP software 7 does not need to manage the DB connection information at each site 8, so there is no need to constantly grasp the environment of each site 8. 7 developer's information management load is reduced.
