Oracle continues to add more and more automated features and advisors to assist with diagnosing and fixing problems. Given all this automation and advice Oracle is providing, a question to ask is whether or not all this advice is "dumbing us down" or "smartening us up". Too often more automation can lead to using these features as a crutch and bypassing the acquisition of key skills and knowledge. Ideally, these features should be tools to help us do our jobs better instead of simply letting Oracle do it for us. The key is to know what help the advisors can provide and know how to use them properly and effectively. The risk is becoming trained to only follow the advisors output, but when a situation arises where our skills and knowledge are needed, it's not there. This presentation will review several cases where the Oracle SQL Tuning Advisor (in particular) isn't able to provide any help with identifying and correcting poorly performing SQL. We'll then review the knowledge and critical thinking skills needed by the DBA or Developer to understand how to make the needed improvements to the code to provide enhanced performance.
