ABSTRACT
This paper presents an algorithm for two-phase locking (2PL) in which deadlocks of distributed transactions for distributed database management systems (DDBMS) are avoided. The method of timestamps is chosen for solving deadlocks and the centralized 2PL algorithm is implemented in DDBMS. The „wait - die" strategy of timestamps mechanism for deadlocks avoiding is presented in this paper. The simulation results of modeling "wait-die" algorithm are given by using GPSS World Personal Version for two and three elements length of distributed transaction.

    M/G/1/ m and M/G/1 queues are considered in the case when the service time and input flow parameters depend on the queue length and are determined at the instants of completion of the service of customers. With the help of an approach based on the idea of Korolyuk's potential method, the Laplace...
