Question 17

Using WS-AtomicTransaction you wrap 3 SOAP-based Web services in a single transaction. When it is time to vote on the outcome of the transaction, 2 of the services vote to commit the changes made during the transaction, but a vote from the third service is not received. What will happen?

  1. The changes are committed because the transaction is considered successful as long as no Abort votes are received.
  2. The changes are rolled back because the transaction is considered unsuccessful when there is a missing vote.
  3. The changes are committed because the transaction is considered successful as long as one Commit vote is received.
