METHOD AND APPARATUS FOR DISTRIBUTED TRANSACTIONS IN A DATA COMMUNICATION NETWORK

摘要

A method and transaction orchestrator node for executing a global transaction in a transaction execution system. The transaction execution system is involving at least one reliable transaction executing instance supporting a reserve/commit protocol and one unreliable transaction executing instance that does not support a reserve/commit protocol. The transaction orchestrator node is receiving a global transaction initiation message involving plural sub transactions for execution by the involved corresponding transaction executing instances and sending a prepare transaction message to involved reliable transaction executing instances for corresponding sub transactions. Upon receiving confirmation of all prepare transaction messages the transaction orchestrator node is sending an execution message to the involved unreliable transaction executing instance for a corresponding sub transaction. If the execution message is successful the transaction orchestrator node is sending a commit prepared transaction to the involved reliable transaction executing instances for the corresponding sub transactions.
