Hi,
there is also this article:
https://tanelpoder.com/2013/02/14/troubleshooting-high-cpu-usage-with-poor-mans-stack-profiler-in-a-one-liner/
However I suppose runtime stats is easier, unless you have an os issue....

My Google Fu is not serving me well today...
I thought I had remembered seeing a catalog of Oracle internal function
names (the ones you'd see in *pstack* output) and their mappings to
Oracle's row source operator names (like "INDEX RANGE SCAN...").
Did I just dream that? Or is it there and I'm just not finding it?
TIA!
