To prevent a Deadlock from occurring at least one requirement for a

deadlock has to be removed:

1. Mutual exclusion: We can use optimistic locking to

prevent mutual exclusion among resources.

2. Resource holding: A thread has to release all its exclusive

locks if it does not succeed in acquiring all exclusive locks

for resources required.

3. No preemption: We can use timeout period for an

exclusive lock to get free after a given amount of time.

4. Circular wait: We can check and ensure that circular wait

does not occur, when all exclusive locks have been

acquired by all the threads in the same sequence
