May be in rigorous 2pl the starvation not possible because until the commit/aborted the lock of SHRED even not released . So,if T2 acquired the S(A) and few time later T1 want to X(A) so wait also after few time T3 want to S(A) but T3 come Later compared to T1 and Rigorous lock says never unlock S & X lock before commit /aborted . Both are in waiting state . When T2 unlock (A) then according to 1st preferred T1 complete its operation by acquired X(A) lock

Sir, 1 doubt.......i think Starvation problem is solved in rigorous 2PL, as if any Resuorce is in shared lock and another transaction requests for exclusive lock, then it is put onto wait condition, but at same time if any other transcation requests for shared lock it was granted in other PL's bcoz of which starvation was occuring but in Rigorous 2PL it would not allow even Shared lock to take place, so starvation problem also gets eliminated? correct?

thank you, sir, but I have one doubt you said Conservative 2PL will solve the deadlock issue as one transaction will acquire all the locks so if T2 comes then it won't be able to get access to locked resources so isn't it a deadlock/ starvation as T2 is still waiting for T1 to end.

And before t2 commits t3 wants shared lock on A.But according to rigorius 2pl it should also wait for commitment of t2. .So after t2 gets commited who will get access to A, T1 or T2?if u please kindly tell this answer.

Which transaction will get lock first... Hope u understand my query

t2 starts transaction with shared lock on A. t1 starts transaction, t1 wants exclusive lock on A, (exclusive lock on shared lock is not given), t1 waits. Now t3 starts transaction, t3 wants shared lock on A, (shared lock on shared lock is given), so t3 starts its transaction in parallel. Now even after t2 is committed, t1 has to wait for t3 also to commit, because t3 already had shared lock on A. (This is what i think, Please correct me if im wrong)
