Description:

The first step in any performance improvement project is benchmarking the existing performance level. What you measure, how you measure it, how you analyze the results and how you define your goals will have a significant impact on your project's success. Do you measure an individual process or the overall throughput? Do you use the 10046 trace, Statspack, ASH or AWR? And how do you identify the critical information within your performance data and provide proof of the improvements to the business? The answers to these questions usually depends on your experience, the available tools and the opinions within your workgroup. The answers should be based on the profile of the system under evaluation and the business needs. This session will present multiple measurement methods and how they can be used most effectively to achieve robust performance.
