functions)

The annotation of the functions that hint at a rowsource are off course all
in http://orafun.info [4]. ;
If anyone knows a function or functions that are not in orafun.info [4] yet,
I am happy to include them.
If anyone finds an error, I am happy to correct it too.

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/
[7]
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!
