Let’s learn some math basics after lunch at #HrOUG2026 @ora600pl.bsky.social on stage

"table scan rows gotten" statistic is worthless! I wanted to create a simple scan for JAS-MIN that would indicate whether your database might suffer from fragmentation and scans of empty blocks. Instead, I fell down the rabbit hole of internal statistics counters… blog.ora-600.pl/2026/10/09/t...

Burning credits continues... ALIS can now create Ansible playbook for out of place patching. Next - I will be testing upgrade 19c->26ai later today. blog.ora-600.pl/2026/10/05/a...

New version of AutoUpgrade is here and ALIS already supports it! ora600pl.github.io/alis/ mikedietrichde.com/2026/09/30/n...

Burning tokens for useful toys continues. I enjoy using SQLcl but if you (like me) use oradebug for testing, investigating and mostly fun, you will be forced to use SQL*Plus. So I instrumented Codex to create a plugin for SQLcl to call upidbg, kpusvcrh and kpusvc2hst :) github.com/ora600pl/soda

#POUG2026 is over - post conference blues kicks in. Thank you @luizafrompoland.bsky.social & @ora600pl.bsky.social and all your team for the fabulous event! Big thanks to all the speakers and attendees for content, questions & discussions. You all make this conference unique. See you at #POUG2027

JAS-MIN got recently a big update: github.com/ora600pl/jas... You can now run it in MCP server mode, which allows you yo use any tool (like Codex, Claude Code or OpenCode) and any model (public or private) for really insightful AI analyzes!

I love autoupgrade.jar functionalities! @mikedietrichde.com @dohdatabase.com

Getting ready for my first talk at OUGN

Beautiful! hackingpassion.com/gpubreach-at...

JAS-MIN recently got a lot of cool updates! github.com/ora600pl/jas... Multi-Model Gradient Regression is used to determine what drives DB Time & DB CPU changes using 4 regression models: Ridge, Elastic Net, Huber and Quantile 95.

Today I’m going to leverage AI to do some nasty things at @doagev.bsky.social #DOAG2025 Join me in room Budapest: my.doag.org/events/userc...

Very Kamil picture and talk at #HrOUG Using #JASMINE and using #beer with a #cli @ora600pl.bsky.social @oracleace.bsky.social @sym42.bsky.social

Last @pougorg.bsky.social meetup this year. @pioro.bsky.social #security

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/n... Hope to see you at HrOUG!

Getting acquainted with JAS-MIN is a good idea, but beware - she can be brutally honest! ora-600.pl/jasmin/jas-m...

Second time this month 🤣🤦‍♂️

11.2.0.3. Windows. NOARCHIVELOG backup using EXP.EXE What can go wrong?

@radek_kut is building a knowledge base about our JAS-MIN: blog.struktuur.pl/blog/jasmin_... 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 github.com/ora600pl/jas... /cc @radekkut.bsky.social

Got accepted to talk at #POUG2025. Jealous to be at the same stage as other #Oracle nerds there. Really, just follow the # and check who got accepted too. See you soon at @ora600pl.bsky.social.

It is time. #POUG2025 agenda in their hands. @ora600pl.bsky.social @radekkut.bsky.social

Who wants to simulate OCI on premises to play with 23ai at home? blog.ora-600.pl/2025/04/12/s...

On Monday, join Oracle ACE Director @ora600pl.bsky.social for his session during Common Polska 🤩 👉 www.common.org.pl/index.php?vi... #OracleACE

JAS-MIN got Google Gemini integration - for now it produces much better results than OpenAI but this is still work in progress. Additionally you can create your own reasonings.txt file to help model with interpreting JAS-MIN report. github.com/ora600pl/jas...

JAS-MIN just got integration with OpenAI ant - to be honest - we're a bit impressed :D github.com/ora600pl/jas...

Congratulations on becoming an Oracle ACE, Piotr Sajda! ♠️ 🎉 Piotr loves windsurfing, skiing, low-level performance (SQL) tuning of Oracle databases, and sharing his experience through blogs. Thanks for the recommendation, @ora600pl.bsky.social! ace.oracle.com/apex/ace/pro... #OracleACE

On @pougorg.bsky.social meetup tomorrow IBM will show us why this approach is not possible on Power VM :D blog.ora-600.pl/2025/02/20/r...

JAS-MIN is getting new features :D github.com/ora600pl/jas... I think that this conference season I'll dedicate to practical usage of JAS-MIN. What do you think about session title: P.U.P.A. JAS-MIN - Practical Usage Performance Analysis using JSON AWR Statspack Miner? :)

At some conferences this year I promised to create a blog post about JAS-MIN to explain how to use this tool - I'm glad I was able to do it before the end of the year 😅 blog.ora-600.pl/2024/12/13/j... Have fun!

Christmas vibes with #POUGTeam & families 🖤 @ora600pl.bsky.social @luizafrompoland.bsky.social

We’re preparing something special #hacking #internals

Improvisation is important part of presenting

🤷‍♂️

Kamil, @ora600pl.bsky.social , reading a json file out loud because the screen refuses to cooperate.

Visualization of a spike by @ora600pl.bsky.social at #ukougdiscover24 when you can't show your screen...

In the absence of a screen @ora600pl.bsky.social draws an database activity chart with beer cans! #UKOUG #UKOUGDiscover24 #UKOUG

Really impressive improvisation by @ora600pl.bsky.social and @gianniceresa.bsky.social still doing their presentation with all technology working against them.

Conference: lovely part of life Dinner: great Drinks: essential Friends: invaluable #ukougdiscover24

I’m really flattered that someone like @chandlerdba.bsky.social is using my tools in his presentation :) 🥃🍻 #ukoug2024
