RH442 (6.2) Performance Tuning 2012-12-19
Student Activity Checklist
Course participants who are new to performance tuning or who desire familiarization with features, methods and best practices
are advised to perform exercises primarily from the Solutions, using the pages marked in bold.
Experienced tuning administrators needing less detailed guidance, and exam candidates wanting a realistic evaluation of readiness,
should repetitively practice the exercises using only the Main Text after completing the Solutions at least once.
