A recent thread on OTN caught my thought where Mr. Jonathan Lewis is
describing query performance issues by referring to stored outlines in the
execution plan. I tried going through the web but couldn’t spot any
satisfying information to figure out these.
Could you please help me know what these do?, and request you to give some
clues, how I can read and value the pieces of information they have in
query performance tuning and direct me to some blog posts, books, or any
article to know these in a better way.
Thank you for all your help and support in this regard.
