Comments:

On success, any changes made to the database during the current save point for the given session will be undone and that save point will be ended. If the last save point for the session was ended then the session will exit the transaction.

On failure, the transactional state of the session will remain unchanged. No change to the database state will occur. A failure during rollback is considered to be a catastrophic database error.
