Apart From the oracle documentation, I used to watch this video many times. http://nzoug.org/paper/how-interpret-explain-plan
The link with video is not opening, I have read the other link which is from the documentation of oracle that is not very good. The good material is on metalink (46234.1) but that is not best because this is not explained using oracle 11.
I need some material like the metalink document but related to oracle 11.
