Overview

This training will enable participants to learn Advanced Tuning and Troubleshooting techniques for Oracle Databases. It will enable the participants to go beyond standard troubleshooting methods and get to advanced techniques analysis to diagnose performance problems. At the end of the training, you will be able to interpret an AWR report and identify whether there is any problem in your database, and if they exist, what are the top problems / root causes of problems.Additional resources( slide deck , practice guide etc) are part of Lecture 10.The topics covered in this course areUnderstanding Database Execution and Resource Utilization- CPU, Memory and I/O usage patterns- When does the Database use what ResourceDesign - Why is it the best and first place to fix Performance Issues- Design Fundamentals- Data Type- Using Constraints- Considering Alternate Storage techniquesWill Adding Hardware solve Performance Issues?- Response Time = Service Time + Wait TimeAccurately Identifying Performance Metrics- Understanding the Wait Event Ecosystemo Wait Event Fundamentalso Diagnosing Problems based on Wait Events- Understanding Ratio Analysiso Memory Issueso I/O Issueso Space IssuesUnderstanding Physical Design Optimizing Storage Configuration- Hardware / Disk Optimization ( Understand your Storage)- Space Vs IOPS Vs MBPS - What do you ask when you need Storage- File placement Strategies - With StripingHow to Read an AWR Report- Important Sections of an AWR Report- Approach to read an AWR Report- Important terms to know to do a 5 minute Analysis and identify the top issue/ problemGet the Best out of SGA Memory- Tuning Buffer Cache - Keep/Recycle Pools, how to configure them- Using Flash Cache- Tuning Shared Pool- Why to Share Cursors- How to identify if Cursors are Shared- Keeping Objects in Shared Pool- Using Result Cache- Tuning PGA- Serial Reuseability- FREE Unused MemoryIdentify I/O Hotspots- File & Tablespace I/O Statistics- Top Objects consuming I/OIdentify Bad SQL- What is Bad SQL- Is it good to do Disk Reads or Memory Reads- Is there a Threshold for Memory and CPU Consumption- What to do after Identifying them
