An integrated processing resume device includes: a request receive part configured to allow an input of a request for an integrated order, the request for an integrated order being a request for integrating a plurality of wholesale services; a resource management part configured to record whether or not each of individual instructions of the wholesale service called by an execution of the integrated order has been successfully executed; and an order resume part configured to, when an individual instruction has not been successfully executed and the integrated order is thereby suspended, then, at a time of resuming the integrated order, reference whether or not an already-having-been-executed individual instruction has been successfully executed, from the resource management part, and, while skipping re-execution of a having-been-successfully-executed individual instruction, execute a not-having-been-successfully-executed individual instruction or a not-yet-having-been-executed individual instruction.

Coordination process restart device and coordination process restart method

In a case where an active system virtual server detects stopping of a heartbeat received from a standby system virtual server, the active system virtual server notifies a coordination apparatus of the detection of the stopping of a heartbeat. In addition, the active system virtual server reports whether or not a service is operating to the coordination apparatus. The coordination apparatus instructs the standby system virtual server to restart the system in a case where the stopping of a heartbeat and the operation of a service are received. The standby system virtual server restarts the service, restarts an operating system, or restarts the operating system in a case where the restart of the service is not successful, in response to an instruction for restarting the system.

Service continuation system and service continuation method between active and standby virtual servers

The present invention achieves automation of validation of a catalog created by a cooperative service catalog creator through a GUI. A catalog verification deviceis a catalog verification devicethat verifies the catalog created by the catalog creation assistance system that assists creation of the catalog used in the orchestrator. The catalog verification deviceincludes a BG cooperation function unitthat is a function unit for communicating with a catalog creation deviceincluded in the catalog creation assistance system, and a catalog verification function unitthat verifies the catalog created by the catalog creation assistance system based on information acquired by the BG cooperation function unit, in which validation of the catalog is performed from perspectives of a mandatory check, a syntax check, and sequence of rules for cooperation among services by performing syntactic analysis of a file when the cooperative service catalog is created by and stored in the catalog creation assistance system.

An Application Program Interface (API) adapter creation apparatus is configured to accept, from a developing engineer, a setting of an execution order of a wholesale service API invoked by internal processing of an adapter API provided by an API adapter, a setting of a request parameter of the adapter API serving as an acquisition source of a request parameter of the wholesale service API, and a setting of a response parameter of the adapter API serving as a reflection destination of a response parameter of the wholesale service API. The API adapter creation apparatus generates a source code based on the accepted settings.

An analysis device for analyzing services on a network includes: a storage unit configured to store, maintenance information collected, from the network, at a predetermined time interval and for each of the services, application rules describing a technique for applying a plurality of types of analysis logics classified by use, and a catalog describing specifications of the analysis logics; a rule application unit configured to, upon receipt of a request related to an analysis target service, apply the maintenance information over a predetermined period of the analysis target service to the application rules; an analysis logic selection unit configured to select the analysis logics for each use based on a result of the application to the application rules; and a collaborative catalog generation unit configured to generate a collaborative catalog including a combination of the catalogs describing the specifications of the selected analysis logics.

Analysis device and analysis method

An API coordination device according to the present invention executes a coordinated service combining wholesale services of a plurality of wholesale providers by launching an API published to a service provider and by launching, in response to an order from the service provider, APIs through which the wholesale providers publish the wholesale services. The API coordination device includes: a catalog/rule management section configured to hold a coordination rule defining API simplification which is to be performed in such a way that, among parameters for executing the coordinated service, a subset of the parameters is hidden and the others of the parameters are published to the service provider; and an execution section configured to read the coordination rule and to launch the API published to the service provider in such a way as to hide the subset of the parameters and publishes the others of the parameters to the service provider.
