Local autonomy, the inherent requirement of multidatabase systems, is especially a big impediment to maintaining global serializability. In this paper, we propose a new global concurrency control scheme to guarantee global serializability without violation of local autonomy. The proposed scheme incurs neither local transaction blackings nor global deadlocks. It also reduces the loss caused by transaction aborts through moving up the validation phase for global serializability to the initial point of the execution of a global transaction.
