Q. Show that a few schedules are possible under the two-phase locking protocol however not possible under the timestamp protocol and vice versa.
Answer: A schedule that is authorized in the two-phase locking protocol but not in the timestamp protocol is:
This schedule isn't allowed in the timestamp protocol because at step 7 the W-timestamp of B is 1.
A schedule that is permitted in the timestamp protocol but not in the two-phase locking protocol is:
This schedule can't have lock instructions added to formulate it legal under two-phase locking protocol because T1 must unlock (A) between steps 2 and 3 and must lock (B) between steps 4 and 5.
