Many researches in managing global transactions in multidatabase systems(MDBS) have been proposed to solve problems of ensuring the global serializability. In these method, a few opportunities are provided to the global transaction to execute concurrently. We concentrate our attention on 1) maintaining consistent database state that is defined by global integrity constraints and 2) investigation into the more accurate indirect conflict situation so that the global transaction manager(GTM) of MDBS provides the higher degree of concurrency. In this paper, we propose a site-locking concurrency control method in MDBS. In our method the more global transaction can be concurrently executed, since the refined boundary of possibility of indirect conflict is offered.
