Contrary to common understanding, the Cost based optimizer is 'forced' in certain situations even if the mode is RULE. Examples are: Use of hints other than RULE, Partitioned tables and indexes, Index-organized tables, Reverse key indexes, Function-based indexes, SAMPLE clauses in a SELECT statement, Parallel execution and parallel DML (i.e. presence of DEGREE on Tables/Indexes), etc. Was this the case?
