As far as I remember it’s available via sql test case builder. Haven’t checked in a while.

Do not like that (also, the way to get the traces)

Apparently Oracle Docs have embedded videos docs.oracle.com/en/database/...

Any idea what the new (?) light blue color in the SQL Monitor reports mean? It's different between those displayed directly in the console, and the stored & opened ones. It looks as if it tries to show active steps, but does it incorrectly in the OCI console. 1 - in console, 2 - same rep stored

One good thing with a MacOS is ability to use iPad as a second monitor.

Looks like it's not available anymore, my SR regarding this was closed with something like "Internal bug was submitted for investigation, but hey, we got that alternate features "Look-up By Error or Error Code's First Argument" or "Search by Stack Trace" added which replace it.
For real?🤦‍♂️

Normally yes. If it asks for a bind value when running this then it uses varchar2 and causes the issue. It looks as if this happens only if you try to Run Script with a single SQL. Once there is more than 1 statement, it doesn't ask for bind and all is good.

If you use Run Script in sqldeveloper, it works just like sqlplus

Have you noticed 23ai FREE background process naming changed from ora_xxxx_SID to db_xxxx_SID? Curious how many shell scripts out there are going to break due to this once (if) 23ai is going to be released

Interesting how tech books are increadibly cheap compared to video courses. TOP www.amazon.com/Troubleshoot... is the best compilation of everything you need to know about Ora perf in 99.9% cases. It's 99$/US, 52€/EU. AOT learn.tanelpoder.com/courses/adva... is most likely great too, but it's 2000$.

What can I say, THANK YOU! #POUG2025 @luizafrompoland.bsky.social

@pougorg.bsky.social was great and it’s time to go. Thank you @ora600pl.bsky.social and the whole team for making it a great place to be. All the best in your next decade. See you some day soon.

Premiere at #POUG2025: @jloracle.bsky.social shows pictures on his slides 😁

Timur at stage

@tmmdv.bsky.social has a modern relationship with performance tools ( some is love, some is hate) - and shares his experience on #POUG2025

Who is this mysterious man? Could it be @chandlerdba.bsky.social ? Strange happenings at #POUG2025 @sym42.bsky.social

And so, the 10th @pougorg.bsky.social #POUG25 starts.
The axeman @ora600pl.bsky.social opening the celebratory champagne bottle the only logical way.
If you don't hear from me again know that I went out having the best of times!

Sabrage with an axe. Yep, @pougorg.bsky.social

So it begins! @pougorg.bsky.social

Is there better news?
No.

Even the docs are not correct at times. A function evaluates its parameters before the call, an expression does not. Try coalesce(1, 1/0)

One minor comment: coalesce is not a function, it’s an expression, which allows short circuit evaluation

This one zerogpt.com but there are many other similar tools for AI detection. I see 87% of AI generated text as ~ plagiarism

You can do an online “director’s cut” 6h version later. No pressure though.

Unfortunately it's 87%+ AI generated text so better not to promote it.

P.S. I really enjoyed seeing paragraph 2.1 - "hints obligate the optimizer to honor actions they specify".
