Udemy – Oracle Performance Tuning-Buffer Cache Waits-Simulated-2

Introduction:

• Briefly introduce the concept of data access in Oracle databases
• Explain the importance of understanding how the Oracle engine decides between buffer cache reads and direct path reads
• Preview the key factors that influence this decision-making process

Tutorial Overview:

Explain that the tutorial will cover the following topics:

• Buffer cache reads: concepts, scenarios, and benefits
• Direct path reads: concepts, scenarios, and benefits
• Key factors influencing the Oracle engine’s decision-making process
• Simulation-based demonstrations to illustrate the decision-making process

Buffer Cache Reads:

• Define buffer cache reads and explain how they work
• Discuss scenarios where buffer cache reads are preferred, such as:
  • Small to medium-sized queries
  • Frequently accessed data
  • Index scans
• Highlight the benefits of buffer cache reads, including:
  • Faster access times
  • Reduced disk I/O
  • Improved performance

Who this course is for:

• Oracle DBA
• Exadata DMA
