Troubleshooting Oracle performance

Oracle Troubleshooting Tips by Donald BurlesonAugust 26,  2015

Question:  I need a method for troubleshooting Oracle performance.  Everyone seems to have their own methods for troubleshooting Oracle performance and they all claim that their troubleshooting method is the only right one!  I'm looking for a troubleshooting methods that is pragmatic and realistic.  Is there are single, correct way to troubleshoot an Oracle performance problem?

Answer:  I agree, there is no single correct method for troubleshooting Oracle performance and I would not trust anyone who says that their Oracle troubleshooting method is the only right approach.

Troubleshooting Oracle performance is a personal endeavor, highly dependent on your Oracle configuration, features, environment and application.  When I troubleshoot Oracle performance I use the methods from my book "Oracle Tuning: The Definitive Reference", but they are many equally valid troubleshooting methods for Oracle performance problems. 

For more complete details on diagnosing a hung database with Oracle Utilities, see the book "Advanced Oracle Utilities: The Definitive Reference".

I also recommend my Oracle script collection which has some excellent scripts for troubleshooting Oracle performance and pinpointing bottlenecks. 

In sum, each shop develops their own method for troubleshooting Oracle performance, using the tools and techniques that are right for them.

Here are some of my notes on troubleshooting Oracle performance:
