Too many commits can kill you! (And everyone else) - checkpoint queue latch internals at #ukougdiscover2025 with @ora600pl
Kamil demonstrating latching issue in a CDB across PDBs using people and beer 🍺!

@fritshoogland It should be… but apparently it’s not. For a lot of customers 🤷♂️

@ora600pl Isn't it obvious that databases all running in the same instance using the same database resources therefore are affected by pressure on these resources?

This week at HrOUG I'm going to talk about noisy neighbors in Oracle multitenant - I am going to focus on latch structures and how they are shared across PDBs. If you can't visit Croatia this week, you may check out this article: blog.ora-600.pl/2025/10/13/noi…
Hope to see you at HrOUG!

@ora600pl For #Oracle #Database, there is already one:
👉 github.com/kubo/rust-orac…
👉 docs.rs/oracle/latest/…
I'm sure they would be happy to welcome more contributors!

@chris_skyflier @FranckPachot A bit of Python automation and we may be able to run some queries 😅

If you've ever felt the need to manually control adaptive lgwr features, this gdb script's got you covered: t.ly/lJIW1 😎
It lets you enable and disable adaptive scalable lgwr, fast log file sync, and log parallelism. Highly experimental, of course!
Example 👇

@tomiw83 You always use it locally :) For now only OpenAI and Google APIs are implemented, but data you are sending is purely statistical - by default even object names are not being send. Only IDs and precomputed stats based on MAD and Pearson. Charts are also generated locally.

Getting acquainted with JAS-MIN is a good idea, but beware - she can be brutally honest!

Tomorrow morning we will be using JAS-MIN to analyze the performance of @OracleDatabase - we will show how JAS -MIN can use new @Google @GeminiApp FLASH models to explain performance issues. It’s RAG baby!

@radek_kut is building a knowledge base about our JAS-MIN:
blog.struktuur.pl/blog/jasmin_pa…
And since it is getting more functionalities almost every week it is probably a good idea 😅

JAS-MIN just learned Median Absolute Deviation which can be used to detect clusters of wait event anomalies! :D

It's time to break the silence. #POUG2025 is not just a fun conference. It can be dangerous.
@evrocs_nl Van Roon was the first to speak loudly about the consequences of attending our event.
