Autonomous coordination for atomicity of transactions in heterogeneous systems

Recent recession has compelled many companies to look for more effective ways to restructure their information and control systems. One solution is to construct the system with the ADS (autonomous decentralized system) technique to cope with changing environments. However, in the heterogeneous autonomous decentralized environments (HADE) each system has its own autonomy and property, and so it's very important to preserve these characteristics even if heterogeneous systems are integrated together. A study of how to achieve the synergistic effect while preserving heterogeneity and autonomy has not been done. In order to achieve the synergistic effect, the different levels of atomicity of cooperative applications in the heterogeneous system are defined which aims to preserve the autonomy and the heterogeneity for each system. In order to ensure the atomicity without knowing the entire system architecture and to realize it by each system autonomously, an autonomous two-phase commitment (A2PC) technique is proposed. This paper also shows the realization technique of A2PC based on the ADS technique.
