Timestamp ordering protocolmaintains the order of transaction based on their timestamps. Atimestamp is a unique identifierthat is being created by the DBMS when a transaction enters into the system. This timestamp can be based on the system clock or a logical counter maintained in the system....
During execution, the lock-based protocol controls the order in which conflicting pairs of transactions are handled. Discuss this Question 6. When a transaction is ___, timestamp-based protocols begin to work. Created Aborted Committed Rollbacked ...
But Timestamp based protocols begin their functioning immediately when a transaction is generated.The sequence for each item accessed by Conflicting action of functioning in the schedule does not break the sequencing which should be confirmed by the algorithm. ...
Aborts are potentially more wasteful than in other protocols because they only occur after a transaction has already executed. Suffers from timestamp allocation bottleneck. Partition-Based T/O When a transaction commits in OCC, the DBMS has check whether there is a conflict with concurrent transactio...
