Having good friends in Oracle is key. And honestly one of the best things in my role. Philippe Fierens, product manager for Oracle's Fleet Patching and Provisioning mailed me yesterday night sharing that there an interesting change…
Retro blog post. Session level parallelism. https://connor-mcdonald.com/2016/01/21/session-level-parallelism
From the vault. New LINESIZE settings for SQLPlus. https://connor-mcdonald.com/2020/01/31/sqlplus-goodies-with-linesize/
Are you also eager to patch your Oracle Database, now that the new Release Updates are here?
Let me show you the easiest way to get those patches so the fun can begin.
Please add me as am an ACE.
I'm not a "full stack" performance specialist as I'm not good with frontend stuff and JavaScript, but I deal with pretty much everything else (app-network interactions, databases, OS and underlying storage I/O).
So I guess I'll call myself a 3/4-stack performance nerd from now on...
That’s so cool and awesome:)
Just wanted to know , do you have a demo script or something to simulate CBC latch ? planning to write a blog post. But not able to reproduce it.
Old blog from 2018, but still worth reading to remind that SQL plan execution is just program execution like any other:

Computers are networks! Even your CPUs are networks, but thats for another day... If you want some holiday reading about how I achieved 66GiB/s and 11M IOPS in a single workstation (back in 2020) and which bottlenecks I hit, check this out!

(Python 3.12+ on Linux can emit perf .map files so that you can see Python function names in the binary stack trace!)

Introducing myself here: My name is Tanel Põder (originally from Estonia, living in Miami) and I'm a long time computer performance nerd.
I work on and write about systematic performance troubleshooting. Also, I'm the guy behind 0x.tools that gives you things like "top for wall-clock time", etc.
