| Abstract: |
As frequent querying of Oracle's dynamic performance views introduces significant result variability and overhead, several commercial third-party Oracle performance monitoring tools have long-since extracted the information directly from the SGA. In this presentation we will take SGA access to the next level by discussing the techniques for retrieving session and statement-level performance data directly from the SGA and applying it to a sample performance monitoring application. We will also demonstrate the performance advantage gained using these monitoring methods. |
