As in the timestamp-ordered system, when a transaction, T1 is initiated, it is assigned a timestamp, TS(T1). However, the system uses the same conflict table as the immediate-update pessimistic control does and resolves conflicts using the rule
If transaction T1 makes a request that conflicts with an operation of active transaction, T2 if TS(T1) < TS(T2), then abort T2, else make T1 wait until T2 terminates. where abort T2 is referred to as a kill because T1 kills T2. a. Showthat the kill-wait control serializes in commit order. b. Give a schedule produced by a kill-wait control that is not serializable in timestamp order. c. Explain why deadlock does not occur in a kill-wait control.
