I've published the final part of my video tutorial and the final part of my mini series "Parallel Execution Skew" at AllThingsOracle.com concluding what I planned to publish on the topic of Parallel Execution Skew.
Anyone regularly using Parallel Execution and/or relying on Parallel
Execution for important, time critical processing should know this
stuff. In my experience however almost no-one does, and therefore misses
possibly huge opportunities for optimizing Parallel Execution
performance.
Since all this was published over a longer period of time this post therefore is a summary with pointers to the material.
If you want to get an idea what the material is about, the following video summarizes the content:
Parallel Execution Skew in less than four minutes
Video Tutorial "Analysing Parallel Execution Skew":
Part 1: Introduction
Part 2: DFOs and DFO Trees
Part 3: Without Diagnostics / Tuning Pack license
Part 4: Using Diagnostics / Tuning Pack license
"Parallel Execution Skew" series at AllThingsOracle.com:

Part 2: Demonstrating Skew
Part 3: 12c Hybrid Hash Distribution With Skew Detection
