A new white paper for SQL Plan Management is now available. Just go to the Query Optimization page in OTN and click the SQL Plan Management with Oracle Database link.
Just like the Optimizer white paper, I've kept the content and format similar to the way Maria organized it so that it will be familiar to those of you that have read previous versions.
Post comments to this blog if you want to give me feedback on the white paper's content. If you want more examples, let me know and I'll add suggestions to my to-do list.
