At present, most of the transaction operations are required in the heterogeneous network environment. The transaction operations not only guarantee transaction implemented correctly and effectively, but also keep transactions under the different environment of consistency and integrity. This paper mainly introduces Lock schemes for resolving the concurrent access conflicts in distributed transaction and the control methods of lock granularities applied for different cases are proposed. It provides solutions to concurrent transaction congestion in the network environment, while optimizing the performance of distributed transaction.
