Concurrent Control and Performance Optimization of Distributed Transaction in Heterogeneous Network Environment

Abstract

Abstract. 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.

An Efficient Merged Concurrency Control Method for Concurrency Conflicts

“…In a distributed database system, the distributed transaction management is an important and complicated part. A transaction is an atomic operation serial nature of ACID (atomicity, consistency, isolation and durability) and the term refers to a distributed transaction management server accessed by multiple objects affairs [1] [2].…”
