WAIT-DIE METHOD
In this method, if a transaction requests to lock a resource (data item), which is already held with a conflicting lock by another transaction, then
one of the two possibilities may occur
1• If $TS(T_{i})$ < $TS(T_{j};) $
- that is$ T_{i}$ which is requesting a conflicting lock, is older than $T_{j}$
- then $T_{i}$ is allowed to wait until the data-item is available.
2• $If TS(T_{i}) > TS(T_{j})$
- that is $T_{i}$ is younger than $T_{j}$ . Then$ T_{i}$ dies.
- $T_{i}$ is restarted later with a random delay but with the same timestamp.This method allows the older transaction to wait but kills the younger one.
