Oracle Database 12c Performance Tuning and Optimization
Slow queries killing your database performance? This course cuts straight to actionable tuning strategies that Oracle DBAs and developers use to squeeze maximum efficiency from 12c. In under 3 hours, you’ll diagnose bottlenecks and implement optimisations that measurably improve throughput.
AIU.ac Verdict: Essential for Oracle DBAs, performance engineers, and backend developers who own database reliability. The course is laser-focused on 12c specifics, so it won’t help if you’re running older Oracle versions or need foundational SQL knowledge first.
What This Course Covers
You’ll explore Oracle’s core performance diagnostics—AWR reports, execution plans, and wait event analysis—then move into practical tuning: index strategies, query optimisation, memory configuration (SGA/PGA), and I/O bottleneck resolution. Each topic connects directly to real-world scenarios where milliseconds matter.
The course emphasises hands-on application through Pluralsight’s sandbox environment, letting you test tuning changes on live 12c instances. You’ll learn to read execution plans like a pro, identify missing indexes, and adjust parameter settings without guesswork. By the end, you’ll have a repeatable diagnostic framework to apply across your own databases.
Who Is This Course For?
Ideal for:
- Oracle Database Administrators: Responsible for uptime and performance; need proven tuning techniques to resolve production slowdowns quickly.
- Backend & Java Developers: Write code that hits the database; understanding query performance and indexing directly improves application responsiveness.
- Database Performance Engineers: Specialise in optimisation; this course fills gaps in 12c-specific tools and methodologies.
May not suit:
- Oracle Beginners: Assumes working knowledge of SQL, database architecture, and basic Oracle administration; not a primer.
- Non-Oracle Users: Entirely 12c-focused; won’t transfer to PostgreSQL, MySQL, or SQL Server environments.
Frequently Asked Questions
How long does Oracle Database 12c Performance Tuning and Optimisation take?
2 hours 56 minutes of video content. Most learners complete it in 1–2 sittings, though you may spend additional time practising in the sandbox environment.
Do I need Oracle 12c installed locally to take this course?
No. Pluralsight provides sandboxed Oracle 12c instances, so you can follow along without managing your own installation.
Will this course help with Oracle 19c or 21c?
Many tuning principles carry forward, but 19c and 21c have evolved diagnostics and features. This course is optimised for 12c specifically.
