Step-by-step learning path for mastering Oracle Performance Tuning, progressing from fundamentals to advanced tuning techniques. It includes concepts, tools, and hands-on practice areas for real-world relevance.

Goal: Understand how Oracle processes SQL and how architecture affects performance.

Topics:
  • Oracle Instance Architecture (SGA, PGA, background processes)
  • Oracle Storage Structures (Tablespaces, Segments, Extents, Blocks)
  • How SQL is parsed and executed
  • Shared pool and Library cache usage
  • Execution plans and query lifecycle
Practice:
  • Use EXPLAIN PLAN and AUTOTRACE
  • Trace a simple SQL with SQL_TRACE and TKPROF
Resources:
  • Oracle Docs: Concepts Guide
  • Book: Oracle Database Architecture by Tom Kyte

Goal: Learn to tune inefficient SQL queries.

Topics:
  • Execution Plans – how to read and interpret
  • Index types and usage (B-Tree, Bitmap, Function-based)
  • Join methods (Nested Loops, Hash, Merge Joins)
  • Cardinality estimation and optimizer statistics
  • Hints and how/when to use them
  • Bind peeking and adaptive plans (11g–19c)
Practice:
  • Use DBMS_XPLAN.DISPLAY_CURSOR and SQL Developer tuning tools
  • Tune a report query with bad performance
  • Compare execution with and without indexes
Tools:
  • SQL Developer
  • AWR/ASH reports
  • TOAD or Quest tuning tools

Goal: Understand how to detect and reduce instance-level bottlenecks.

Topics:
  • Wait Events & Time Model (V$SESSION, V$SYSTEM_EVENT)
  • Top wait classes (I/O, CPU, Concurrency, Network)
  • Latches, locks, buffer cache inefficiency
  • SGA & PGA tuning (Automatic Memory Management)
  • Temp usage and redo inefficiencies
Practice:
  • Use V$ACTIVE_SESSION_HISTORY (ASH)
  • Generate and analyze AWR reports
  • Identify top resource-consuming sessions
Tools:
  • AWR / ADDM Reports
  • Enterprise Manager (OEM Cloud Control)

Goal: Dive into advanced query patterns and procedural code tuning.

Topics:
  • Analytical functions and performance
  • PL/SQL tuning: BULK COLLECT, FORALL, pipelined functions
  • Materialized views and query rewrite
  • Partitioning for performance
  • Parallel execution
Practice:
  • Refactor PL/SQL code using BULK COLLECT/FORALL
  • Test parallel queries and indexing on large datasets
  • Tune long-running PL/SQL packages

Goal: Proactively tune the database using monitoring and preventive techniques

Topics:
  • Baseline and threshold management
  • SQL Plan Management (SPM)
  • Real-Time SQL Monitoring
  • Resource Manager
  • Baseline capture & comparison
Practice:
  • Set up SQL Plan Baselines for critical queries
  • Use OEM to configure resource plans
  • Compare AWR baselines for regression analysis

Goal: Apply all knowledge in simulation and real-world-like tasks.

Projects:
  • Tune a batch job slowing down weekly
  • Simulate and resolve buffer busy waits
  • Analyze & tune top 5 high-load queries from AWR
  • Implement SPM to fix regression after patch

Certifications & Courses:

Oracle Certified Professional (OCP) – Performance Tuning (11g/12c/19c)

What will the learner be able to do after this course?

After completing the Oracle Performance Tuning course, the learner will be able to analyze and optimize poorly performing SQL queries, configure memory components, and fine-tune database parameters for improved efficiency. For example, in a retail application facing slow report generation, the learner can identify high-cost queries using AWR reports, rewrite inefficient SQL joins, and create appropriate indexes—reducing report generation time from minutes to seconds and significantly improving user experience.

What Our Students Say

Before joining the SQL Performance Tuning course, my queries used to run forever. Now, I understand how indexes work, how to read execution plans, and how to optimize queries like a pro. The trainer explained everything with real-time examples. Highly recommended for anyone serious about database performance.

Rakesh Kumar

- Software Developer

As a backend developer, I often struggled with slow queries. After this training, I feel confident tuning even complex SQL statements. The hands-on labs were the best part—everything was practical, not just theory.

Sandhya V

- Backend Engineer

This was not just a course—it was a game changer. From learning how to identify performance bottlenecks to using tools like SQL Profiler and Execution Plans, everything was taught in an easy-to-follow way. I could apply the concepts immediately at work.
