I don’t remember for sure (after all, I did write this in March) but I’m pretty sure that I ran all of these tests on 10g when I first wrote the article. I think that I only used a 9i install to get screenshots of the outline editor.

Doesn’t seem to work for me in 10.

It seems to ignore the hints given unlike in your example.
It worked great in 9. Any suggestions?

Thanks for the reply and the new info. It’s interesting that stored outlines in the manner of 9i/10g are going away but replaced in 11g by, well, a new incarnation of stored outlines. I would have guessed that the new thing would be an evolutionary development from SQL profiles instead — but that’s just based on profiles being the newer technology, not on a very deep understanding of the differences. I will keep an eye out for something on your blog related to profiles in the meantime.

Yes I’m planning on a third part. But it doesn’t stop there… in 11g Oracle has completely overhauled SQL Tuning with a new feature called SQL Plan Management (which is the foundation of fully automated SQL tuning in 11g). It’s essentially stored outlines on super-steroids. In fact in 11g they’re finally deprecating stored outlines, officially. It’ll be a little work and so it’ll probably take awhile but I’m looking forward to putting some write-ups together!

This is all very interesting — thanks.

Will there be a Part 3 describing profiles?
