AWR Report Mastery
- Practice reading AWR reports until you can identify bottlenecks in under 5 minutes
- Focus on Top 5 Timed Events section - this is where most performance issues appear
- Memorize common wait events: db file sequential read, db file scattered read, log file sync, CPU time
- Understand the difference between background and foreground waits
- Learn to correlate wait events with SQL statements in the AWR SQL sections
Execution Plan Reading
- Practice with DBMS_XPLAN.DISPLAY_CURSOR for real execution plans
- Always read execution plans from inside-out and top-to-bottom
- Focus on cardinality estimates vs actual rows - large differences indicate statistics issues
- Memorize common operations: TABLE ACCESS FULL, INDEX RANGE SCAN, HASH JOIN, NESTED LOOPS
- Understand the cost model and when the optimizer chooses different access paths
- Practice identifying missing indexes from execution plans
V$ Views and Data Dictionary
- Create flashcards for important V$ views: V$SESSION, V$SQL, V$SYSTEM_EVENT, V$SESSION_WAIT
- Know which views show current state vs historical data
- Understand the relationship between V$ views and AWR/ASH data
- Practice joining V$ views to diagnose performance issues
- Memorize key columns in performance-related views
Memory Management
- Understand the three memory management modes and when to use each
- Know the components of SGA: buffer cache, shared pool, large pool, Java pool, streams pool
- Memorize key initialization parameters: MEMORY_TARGET, MEMORY_MAX_TARGET, SGA_TARGET, PGA_AGGREGATE_TARGET
- Practice using memory advisors to determine optimal sizing
- Understand the impact of undersized PGA on sort and hash operations
SQL Tuning Advisor
- Practice running SQL Tuning Advisor through both EM and DBMS_SQLTUNE package
- Understand the types of recommendations: statistics, SQL profile, indexes, SQL restructuring
- Know when to accept SQL profiles vs implementing manual changes
- Learn the difference between comprehensive mode and limited mode
- Practice creating and using SQL Tuning Sets
Hands-On Practice
- Set up Oracle 19c on Oracle Cloud Free Tier or VirtualBox
- Create performance problems intentionally and practice diagnosing them
- Generate AWR reports for different workload scenarios
- Practice with poorly performing queries and tune them systematically
- Experiment with different initialization parameters and observe their impact
- Use sample schemas (HR, OE, SH) for realistic practice scenarios
Exam-Specific Preparation
- The exam heavily focuses on interpreting reports and recommending actions
- Scenario-based questions are common - practice decision-making, not just memorization
- Time management is critical: 78 questions in 120 minutes = 92 seconds per question
- Flag difficult questions and return to them - don't get stuck
- Understand not just WHAT to do, but WHEN and WHY for each tuning technique
- Oracle recommends specific tools for specific problems - know these mappings
Key Parameter Memorization
- Create a cheat sheet of critical parameters and their default values
- Focus on parameters affecting optimizer behavior: OPTIMIZER_MODE, OPTIMIZER_INDEX_COST_ADJ, OPTIMIZER_INDEX_CACHING
- Know memory parameters and their relationships
- Understand parameters related to parallel execution
- Memorize AWR snapshot interval and retention parameters
Exam Day Tips
- 1Arrive at testing center 15 minutes early or ensure stable internet connection for online proctoring
- 2Read each question carefully - Oracle exams often include subtle wording that changes the answer
- 3Watch for 'BEST' answer questions - multiple answers may be correct, but one is optimal
- 4For AWR report questions, focus on wait events and top SQL sections first
- 5Eliminate obviously wrong answers first, then choose between remaining options
- 6Don't spend more than 2 minutes on any single question initially - flag and move on
- 7Trust your preparation - your first instinct is usually correct for scenario questions
- 8For execution plan questions, look for full table scans on large tables and missing indexes
- 9If a question asks about a specific tool or advisor, recall its primary purpose and limitations
- 10Remember that 66% passing score means you can miss 27 questions - don't panic over difficult ones
- 11Review flagged questions if time permits, but avoid changing answers unless you're certain
- 12For memory management questions, consider both automatic and manual approaches
- 13SQL tuning questions often have multiple valid approaches - choose the one Oracle recommends first
