In this paper, a method for concurrency control in distributed DBMSs, called Permission Test Method is proposed. The PT method satisfies the basic requirements for concurrency control, that is, it executes the transactions in a serializable order, deadlocks do not appear and indefinite postponment is prevented by the method. In PT method, transactions, which are permitted to run, are not aborted unless a related site failure occurs. Furthermore, the complexity analysis indicates that the algorithm will work in a reasonable amount of time. The PT method provides more concurrency than the Basic Timestamp Ordering and Two-Phase Locking techniques. © 1987, ACM. All rights reserved.
