Resolving High CPU Usage on Oracle Servers

This case study demonstrates a top-down tuning methodology that was applied to a performance problem involving high CPU usage on a database server.
The diagnostics that were collected and analyzed for this problem include: operating system (OS) data such as vmstat and top; statspack, and trace event 10046 with TKProf output.
The conclusion from analyzing the collected data was that a specific query was consuming most of the CPU and needed to be tuned.

We present various ways of tuning the query as well as verification that the recommended solution solved the problem.
