Concurrency Control for Transactional Composite Services

A composite service can be built from Web Services, and, its workflow can be specified using BPEL4WS. Many composite services are long-running transactional processes. This paper proposes a concurrency control scheme for executing transactional composite services. The scheme uses the information gathered from the workflow specifications of the composite services to guarantee the correctness of the execution of the composite services. Empirical studies were carried out to compare the performance of the proposed scheme with the strict two-phase locking scheme.
