Oracle 12c SQL Tuning - the Ultimate Guide

Become confident in tuning Oracle SQL statements by understanding how the Oracle optimizer works and learning how to control and influence its decisions.

When a SQL query suddenly becomes slow with no obvious reason, you need the right knowledge, tools, and methodology to identify the bottleneck and apply the correct solution. This course teaches you exactly how to do that, using a hands-on, practical approach.

The course goes beyond theory. Every concept is followed by real implementation exercises, allowing you to practice SQL tuning techniques step by step using Oracle Database 12c.

You will learn how to:

• Troubleshoot SQL performance issues methodically

• Understand Oracle optimizer architecture and internal operations

• Influence optimizer behavior using:

  • SQL Profiles

  • SQL Plan Baselines (SPM)

  • Directives

  • SQL Hints

  • Cursor Sharing

• Use Oracle SQL performance advisory tools, including:

  • SQL Tuning Advisor

  • SQL Access Advisor

  • Optimizer Statistics Advisor

  • SPM Evolve Advisor

  • SQL Performance Analyzer

• Apply advanced SQL tuning techniques, such as:

  • Histograms

  • Advanced indexing strategies

  • Server Result Cache

  • Star Transformation

This course is designed for Oracle developers and DBAs who want to move beyond basic indexing and execution plans. You will learn how to trace SQL statements, analyze execution behavior, and make informed tuning decisions.

By the end of the course, you will be able to identify SQL performance bottlenecks, understand why they occur, and apply effective tuning solutions with confidence.

Join this learning journey and master one of the most valuable skills in Oracle performance tuning.
