An apparatus selects services to be used by a user from a plurality of candidates for services used to execute a program. The apparatus acquires a constraint condition and the program. When executing the acquired program, the apparatus specifies a set of services satisfying the constraint condition from the plurality of candidates based on a code pattern included in the program, and uses the specified set of services to execute the program.

Apparatus and method to select services for executing a user program based on a code pattern included therein

An apparatus tests specific processing performed by plural computing machine resources provided by one or plural computers. The apparatus adds an instruction request command to request an instruction from the apparatus at a predetermined position in a source code of the specific processing performed by each computing machine resource, and generates the source code with an additional command. In response to execution of the instruction request command in one of the plural computing machine resources during execution of the specific processing, the apparatus refers to the memory that stores instruction information by which the instruction request command added to the source code with the additional command executed by each computing machine resource is associated with processing performed by the computing machine resource, and instructs the one of the plural computing machine resources which has executed the instruction request command to perform the processing corresponding to the executed instruction request command.

An information processing system includes a management apparatus that includes a first processor configured to store first information on an access token indicating that a right to call an application programming interface exists and second information on the application programming interface in a memory, and execute an exchange for a different access token by using the first information and the second information stored in the memory; and a client apparatus that includes a second processor configured to provide the application programming interface or use the application programming interface by utilizing the exchange for the different access token by the management apparatus.

Information processing system, information processing apparatus, and information processing method

A memory holds a code pattern, a first template indicating a format of a program which defines that a system performs certain processing in response to a processing request, and a second template indicating a format of a program which sends the processing request to the system via a network. A processor generates, by acquiring a first program, detecting a first code matching the code pattern in the first program, and using the first code and the first template, a second program which defines that the system performs processing corresponding to the first code. The processor generates, by detecting a second code dependent on the first code in the first program and using the second code and the second template, a third program to be executed by another system different from the system.

Information processing apparatus and method

An analysis apparatus compares first code describing a plurality of first components with second code describing a plurality of second components, to extract difference components. The analysis apparatus sends a plurality of requests to an execution apparatus on which the plurality of second components are deployed, obtains first log information indicating the execution state of each difference component, and specifies relevant requests related to the execution of the difference components. The analysis apparatus sends the specified relevant requests to the execution apparatus and obtains second log information indicating the execution state of each of the plurality of second components. The analysis apparatus generates path information about second components executed in response to each relevant request among the plurality of second components, on the basis of the second log information.

Apparatus and method for collecting and analyzing logs to obtain information about program components used by applications

A relationship analyzing unit generates an assumed endpoint based on class relationship information. A log analyzing unit refers to the class relationship information and extracts noun-verb information from an access log, and an actual endpoint generating unit generates an actual endpoint by converting a verb in the noun-verb information into an HTTP method name and converting a noun therein into a path. A merge unit identifies an endpoint included in assumed endpoints generated by the relationship analyzing unit, as a specification endpoint, among actual endpoints.

Information processing device and specification creation method

A determination unit determines a precondition indicating an expected state of a system that is to execute processing corresponding to an operation, and a postcondition indicating an expected state of the system that has executed the processing corresponding to the operation, based on a work log of previously-performed work. An association unit associates each of a plurality of operations with an operation whose precondition matches a postcondition of the each of the plurality of operations. A search unit searches for a path that starts from an operation whose precondition matches an initial condition satisfied by an operation object system, traces an associated operation, and reaches an operation whose postcondition matches a target condition indicating a target state of the operation object system after work. A generation unit generates an operation procedure in which operations on the path found by the search are arranged in order.

Operation search method and operation search apparatus

Common parameters in common between a plurality of request logs are extracted from parameters in the plurality of request logs. The plurality of request logs is obtained when a request is executed by a process that uses a plurality of components. A common parameter different from a common parameter extracted for another process among the extracted common parameters is determined as an identification parameter that identifies the process. This allows accurately categorizing the process based on a log to be obtained when the process is executed.

Method for analyzing request logs in advance to acquire path information for identifying problematic part during operation

A message determination apparatus includes a storage unit that stores messages generated in a system, an extracting unit that extracts a message whose occurrence interval is in a certain range from the messages stored on the storage unit, and a determining unit that determines whether the occurrence interval of the message extracted at the extracting unit is out of a certain range in the messages generated in the system. Accordingly, a fault on the system can be detected when the occurrence interval is out of a certain range.

Apparatus and program for detecting abnormality of a system

An information transmission device stores an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device. When transmission of information is requested from the information processing device, the information transmission device specifies an identifier representing an information processing device. The information transmission device acquires an identifier representing a storage device stored in association with the specified identifier. The information transmission device transmits information on a request for transmission by the information processing device to the storage device represented by the acquired identifier.
