Consider the following two-phase locking protocol. Suppose a transaction T accesses (for read or write operations), a certain set of objects {O1,…,Ok}. This is done in the following manner:Step 1. T acquires exclusive locks to O1,…,Ok in increasing order of their addresses.Step 2. The required operations are performed.Step 3. All locks are released.This protocol will
In a database system, unique timestamps are assigned to each transaction using Lamport’s logical clock. Let TS(T1) and TS(T2) be the timestamps of transactions T1 and T2 respectively. Besides, T1 holds a lock on the resource R, and T2 has requested a conflicting lock on the same resource R. The following algorithm is used to prevent deadlocks in the database system assuming that a killed transaction is restarted with the same timestamp.If TS(T2) < TS(T1) thenT1 is killedelse T2 waits.Assume any transaction that is not killed terminates eventually. Which of the following is TRUE about the database system that uses the above algorithm to prevent deadlocks?
Consider the following two statements about database transaction schedules:I. Strict two-phase locking protocol generates conflict serializable schedules thatare also recoverable.II. Timestamp-ordering concurrency control protocol with Thomas’ Write Rule cangenerate view serializable schedules that are not conflict serializable.Which of the above statements is/are TRUE?
