In this protocol, every transaction issue lock and unlock requests in two phases. (i) Growing phase : In this phase, transaction can obtain new locks but cannot release any lock. (ii) Shrinking or contracting phase : In this phase, transaction can release locks, but cannot obtain new locks. Lock Point : In growing phase, the point at which transaction has obtained its final lock is called Lock Point. In two phase locking protocol, all transactions can be ordered according to their lock points. Transactions T1 and T2 in Figure 8.9 follows two phase locking protocol. 356 Introduction to Database Management System Not-possible because B is locked in shared mode by T2 and T1 have to wait for B. Not-possible because A is locked exclusively by T1 and T2 have to wait for A.
