Re: parallel queries using RULE

Any hint, except the RULE hint, will invoke the CBO. Also any parallel settings (degree or instances) invoke the CBO from 7.3 and on.

An excellent doc available on MetaLink which details whether the CBO or RBO will be used is:
  Note 66484.1 - "Which Optimizer is Used ?"

So to answer Nigel's original question, NO, you cannot use PQO with RBO regardless of whether the table is partitioned.
