Looking forward for the next edition of @chris.antognini.ch book after his presentation at @soug.ch day in Zurich #besharing

Good idea for a Christmas gift: @chris.antognini.ch’s third edition of “Trobleshooting Oracle Performance” will be published on 21 December

Apress has begun publishing information about TOP3. The waiting is almost over :-) link.springer.com/book/9798868...

Had a closer look at the implementation of the CURSORTRACE event... and encountered a few surprises: t.ly/jQG6B

This is news about a legend that I completely missed! Fortunately, @economist.com filled that gap.

If you want to know how the new JOIN TO ONE syntax can help to reduce complexity of SQL queries and avoid incorrect results in star schemas, read my lastest blog post: danischnider.wordpress.com/2026/07/18/j...

Critics of AI complain when models make up confident-sounding but factually incorrect answers. When there is no factually correct answer, however, AI’s shortcomings can be even more pronounced and less easy to detect

Oracle provides an APEXlang compiler, but not a public parser for building custom tooling. Grisselbav’s APEXlang Parser fills that gap. In this blog post, I show how it enables static code analysis by detecting a security vulnerability in an Oracle APEX app. www.salvis.com/blog/2026/06...

I wrote about the Reflecting Pool

The perfect guide to the oracle optimizer blogs.oracle.com/optimizer/or... Kudos @vldbb.bsky.social

New video! For 99% of databases and 99% of the time, the default settings for the optimizer will be fine for your performance needs. But occasionally, you might need to divert to get the most out of it. youtu.be/hm3O7hgup4g

Settler crimes against Palestinians in the West Bank are “not just personal tragedies”, laments Nimrod Novik. They also undermine “Israel’s security, its moral fabric and its international standing”

Israel’s defenders argue rightly that the Middle East has no simple diplomatic solutions. But the country’s overwhelming military superiority is not a solution in itself

I've been busy in the last months! Announcing a brand new "Practical Exadata Performance" training course! I'm not aware of any other training *like this* offered in the world. 😎 Also, a *free* seminar! Exadata is an awesome platform, if used right! learn.tanelpoder.com

We couldn't have done it without her.💐

Reasons why SELECT * is bad for SQL performance: An old blog (with Oracle-specific examples) with a whole range of reasons why. It's not only about network traffic and SQL plan execution, but client side processing and memory usage as well. tanelpoder.com/posts/reason...

IMO that's good news! Bitcoin mining is no longer profitable after crypto's latest downward turn, analyst says www.cnbc.com/2026/02/24/b...

After a decade of planning, editing, delays due to my own busyness, further editing and waiting for 23c, the release of 26ai and my pre-retirement finally unblocked the situation. I have agreed with Apress to publish the third edition of Troubleshooting Oracle Performance in 2026. #TOP3

From what I see, #OracleDatabase between version 23.3 and version 23.26.1 ships with a buggy TRCSESS script. To fix it, just correctly set the variable JDK_HOME at line 54. I seems that the problem was introduced by the change "adadhich 04/12/23 - use s_jdkLocation".

This is an interesting case of censorship. The two images show the front covers of the same book. One was printed in Switzerland and the other by Amazon. I suppose Donald's ego is just too fragile.

The journey that began with Trivadis in 1999 ends today. It has been a great and memorable one. I had the chance to make so many positive experiences and meet great people inside and outside the company. But it's time for me to move on and enable pre-retirement mode.

I’m a simple man. While Oracle people are ecstatic about ASSERTION in the just released version 23.26.1 of the Oracle Database, I’m happy to see something as simple as FILTER :) 🧵

Finally.

“Venezuela needs a civilian government constrained by law, respectful of individual freedoms, accountable to voters and capable of rebuilding institutions,” Ricardo Hausmann writes in a guest essay. “Donald Trump appears not to understand this”

In 2025 the energy balance of our PV system (10 kWp) improved thanks to better weather (+780 kW) and some adjustments of pool and EV consumption. The self-consumption of 56% is good and could be taken to 60% with further optimisation. Unfortunately, I wasn't able to acquire a V2H wallbox... WIP.

Running a giant software business used to be fun. Artificial intelligence is now turning that model on its head. Nowhere has the transition been as unsettling as at Oracle

I just noticed that "Previous Favorites" are now available in my MOS account. That said, the list doesn't contain everything I was expecting...

I'm happy with the performance of my new ThinkPad P14s. Only thing that could be better is a lower fan noise by heavy load. But, let's face it, running 5 VMs with 30+ active Oracle Database instances isn't the most common load for a notebook ;-)

A very insightful interview published by The Changeover Podcast. www.youtube.com/watch?v=cVAV...

As a companion to yesterday's Bounces deep dive into 1xBet's problematic presence in tennis, I chatted with Ross Higgins of @bellingcat.com about their investigations and why sports brands that *should* be prestigious keep doing deals with this dirty company. www.benrothenberg.com/p/1xbet-cont...

New: On 1xBet, the strange and shady company which has become rapidly more visible across tennis in 2025 despite *many* reasons for tours, tournaments, and federations to steer clear of its mess. Lots of odd details here, free for all to read at Bounces: www.benrothenberg.com/p/1xbet-tenn...

The AI age looks likely to belong not to enablers of technology like Accenture but to its originators

Today is a special day for me: it is the last working day of 2025. I will do my best to spend the rest of the year doing whatever makes me and my dearest ones happy😃

In other #databs news, Salesforce is buying Informatica. I guess Salesforce is where aging data tools go to die.
