Welcome!  Here you'll find my various series on "improving Oracle performance".  My first series of articles was on resolving Oracle contention.  In each entry you'll find a short summary of a particular type of contention – locks, latches, buffer busy, etc -- and how to identify and resolve them. 

My next series of articles will focus on tuning.  Again, each article will focus on a particular facet of tuning and how to identify and resolve them.

I've also included copies of my past tech articles and presentations for your reference. 

• Resolving Oracle Contention Series - learn to identify and resolve types of Oracle contention
