Actually, Oracle inserts implicit COMMIT after each DDL.
So, if you have:
BEGIN;
INSERT INTO foo (bar) VALUES (1);
CREATE INDEX foo_bar ON foo (bar);
-- Here Oracle will insert implicit COMMIT, thus your foo table will
have value 1 commited.
-- And here Oracle will BEGIN a new trasaction.
INSERT INTO foo (bar) VALUES (2);
ROLLBACK;
-- And you will rollback the insert of value 2. Value 1 remains in the table,
-- because it is already committed.
