Hong Zhao, Bao Xi-qing, Yao Ying · International Conference on E-Business and E-Government · 2012
The high loose coupling is the feature of web service composition transaction, which leads to the limitation of the traditional transaction processing mechanism when dealing with transactions. The traditional transaction processing mechanism weakens its feature and easily fails to process the entire transactions because of maintaining the atomicity of transactions. The paper, analyzing the invoking process of web service composition and the demand of transaction processing, proposes a model of web service composition transaction and analyzes the solution of the handling mechanism of the transaction error according to the model. Meanwhile the paper introduces a thought of single transaction coordinator (STC) and combination transaction coordinator (CTC), and analyzes error recovery mechanism based on the candidate service queue (CSQ).
