10.4. Transaction Outcomes
10.4.1. About Transaction Outcomes
There are three possible outcomes for a transaction.
- Roll-back
- If any transaction participant cannot commit, or the transaction coordinator cannot direct participants to commit, the transaction is rolled back. See Section 10.4.3, “About Transaction Roll-Back” for more information.
- Commit
- If every transaction participant can commit, the transaction coordinator directs them to do so. See Section 10.4.2, “About Transaction Commit” for more information.
- Heuristic outcome
- If some transaction participants commit and others roll back. it is termed a heuristic outcome. Heuristic outcomes require human intervention. See Section 10.4.4, “About Heuristic Outcomes” for more information.
