GridTP Services for Grid Transaction Processing

Zhengwei Qi, Jinyuan You, Ying Jin, Feilong Tang

Abstract: We propose a new service-oriented Grid Transaction Processing architecture called GridTP based on the OGSA platform and the X/Open DTP model. GridTP services provide a consistent and effective way of making existing, autonomously managed databases available within Grid environments. In the Data Virtualization Services layer, Grid applications, via the WSDL-style TX portType, delineate global transaction boundaries among virtual organizations. In the Common Resource Model layer, GridTP services, via the X/Open-defined interface XA between Database Managers and the Transaction Manager, manager local transactions in heterogeneous databases. Therefore, GridTP has made a seamless mechanism for embedding the X/Open DTP model in Grid services to support Grid Transaction Processing, which provides one promising reference implementation for the future Grid Data Services.
