Oracle Support Case Studies

As I was poking around metalink, I found the following extremely interesting section. It’s in a very obvious place, but it’s new, so many of you may have not noticed it.
It’s called “Support case studies” and provides some amazing articles, such as :
Resolving High CPU Usage on Oracle Servers
The Mysterious Performance Drop
Diagnosing Unsuccessful CRS root.sh Issues
Intense and Random Buffer Busy Wait Performance
Here’s how to go there:
1. Login to metalink
2. Click the Knowledge tab
3. Look at the left column for “Support Case Studies”
