Computer system and control method for distributed transaction

A computer system comprising a plurality of service execution systems each configured to execute a service for implementing an application that executes a distributed transaction,

• at least one of the plurality of service execution systems being configured to generate determination information for determining whether rollback of the distributed transaction is required and to transmit the determination information to another one of the plurality of service execution systems, and
• the another one of the plurality of service execution systems that has received the determination information being configured to determine, through use of the determination information, whether the rollback of the distributed transaction is required,
• wherein one of the plurality of service execution systems that executes the service being a start point of the distributed transaction is configured to:
• generate the determination information;
• and
• transmit, to another one of the plurality of service execution systems, a call request for instructing the execution of the service together with the determination information, and
• wherein the another one of the plurality of service execution systems that has received the call request is configured to determine, based on the determination information, whether the rollback of the distributed transaction is required.

A control method for a distributed transaction of a computer system including a plurality of service execution systems each configured to execute a service for implementing an application that executes a distributed transaction, the control method comprising:

• a first step of generating, by at least one of the plurality of service execution systems, determination information for determining whether rollback of the distributed transaction is required and transmitting the determination information to another one of the plurality of service execution systems;
• and
• a second step of determining, by the another one of the plurality of service execution systems that has received the determination information, whether the rollback of the distributed transaction is required through use of the determination information,
• wherein the first step includes a step of generating the determination information by one of the plurality of service execution systems that has received a call request for instructing the execution of the service, and
• wherein the second step includes the steps of:
• obtaining, by one of the plurality of service execution systems that executes the service being a start point of the distributed transaction, the determination information from another one of the plurality of service execution systems that executes the service relating to the distributed transaction;
• and
• determining, by the one of the plurality of service execution systems that executes the service being the start point of the distributed transaction, whether the rollback of the distributed transaction is required based on the determination information.
