Expert Solution & Answer
Chapter 12, Problem 11RQ
Explanation of Solution
Two-phase commit protocol:
The two-phase commit protocol is used to make sure that the transaction atomicity and
The need of this protocol helps to make sure that the database changes form remote site is coincided. If not, each and every transaction is undone to sustain a consistent database.
There are two phases in two-phase commit protocol. They are,
- Preparation
- The final COMMIT
Phase 1: Preparation
- The coordinator transfers the message from PREPARE TO COMMIT to all subordinates...
