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

An information processing system comprising:

• a first processor configured to operate an application;
• a second processor configured to receive a transaction with respect to the data from the first processor;
• and
• a third processor configured to operate as a stand-by processor while the second processor operates as an active processor,
• wherein the first processor generates a temporary transaction identifier for identifying the transaction, adds the generated temporary transaction identifier to a first request about the transaction, and transmits the first request to the second processor and the third processor,
• when the second processor receives the first request, the second processor determines a transaction identifier for identifying the transaction, determines a data identifier for identifying data to be processed by the first request, adds the transaction identifier and the data identifier to a response to the first request, and transmits the response to the first processor,
• when the first processor receives the response, the first processor adds the transaction identifier and the data identifier contained in the response to a second request about the transaction, and transmits the second request to the second processor and the third processor, and
• the third processor manages transaction information for associating the temporary transaction identifier contained in the first request with the transaction identifier and the data identifier contained in the second request, and upon receipt of a commit request about the transaction from the first processor, the third processor performs commit processing on the transaction based on the transaction information.

An information processing apparatus included in an information processing system including a second processor configured to store data used by an application, and accept a transaction of the data;

• and a third processor configured to operate as a stand-by apparatus while the second processor operates as an active apparatus, the information processing apparatus comprising:
• a first processor configured to generate a temporary transaction identifier as a temporary identifier for identifying the transaction, wherein
• the first processor adds the generated temporary transaction identifier to a first request for the transaction, and transmits the first request to the second processor and the third processor;
• and upon receipt of a response to the first request from the second processor, the first processor extracts a transaction identifier for identifying the transaction and a data identifier for identifying the data from the response, adds the transaction identifier and the data identifier to a second request about the transaction, and transmits the second request to the second processor and the third processor.

An information processing method by an information processing system that has a first processor in which an application operates, a second processor configured to store data used by the application, and receive a transaction of the data from the first processor, and a third processor configured to operate as a stand-by apparatus while the second processor operates as an active apparatus, the method comprising:

• by the first processor,
• generating a temporary transaction identifier for identifying the transaction,
• adding the generated temporary transaction identifier to a first request for the transaction, and
• transmitting the first request to the second processor and the third processor,
• when the second processor receives the first request,
• by the second processor,
• determining a transaction identifier for identifying the transaction,
• determining a data identifier for identifying data to be processed by the first request,
• adding the transaction identifier and the data identifier to a response to the first request, and transmits the response to the first processor,
• when the first processor receives the response,
• by the first processor,
• adding the transaction identifier and the data identifier contained in the response to a second request for the transaction, and
• transmitting the second request to the second processor and the third processor, and
• by the third processor,
• managing transaction information for associating the temporary transaction identifier contained in the first request with the transaction identifier and the data identifier contained in the second request, and
• upon receipt of a commit request about the transaction from the first processor, performing commit processing on the transaction based on the transaction information.
