Thank you Niall and Lex for your responses.  

We have a 3rd-party Oracle8i system running under the RULE-based optimizer. We have identified a handful of poor performing SQLs. We can't change the generated SQLs therefore we are looking into using stored outlines to store the access plans for those exceptional SQLs. Our thought is CBO would kick in for the SQLs with the stored outlines and RBO would kick in for the other acceptable SQLs. Does this sound like it will work?
