Ready for my first of two talks during #ittage25: today I’m going to introduce Java developers to database tuning. Actually any developer. And it’s a pretty light into 🙃Hope to see you at 14:00!

🚀 Quick Oracle tip: use multiple FOR clauses in METHOD_OPT to keep stats lean while building a histogram only where it matters. Small tweak, big control. 😉 And I can never remember the correct syntax, so I wrote it down More: martincarstenbach.com/2025/12/09/m...

Bind variables boost Oracle performance, cut hard parses, and reduce SQL injection risk. Many of you know this, but this time I did the maths showing the overhead of not sharing cursors. You can find the details here: martincarstenbach.com/2025/12/02/m...

There are typos, and there are funny typos, like: $ gut pull Feels like it sometimes but it didn’t really do it for me 🤦

I've just released swingbench 2.8 (#Oracle AI Database load generator). Now with a HTML front end. You can read all about it here www.dominicgiles.com/swingbench/2...

📚 New Reading List is out! 🤖 #AI is back, ☁️ #Oracle Cloud expanding and 💬 #JavaScript can finally talk with #PL/SQL

Three small letters in your AutoUpgrade config file, and your SecOps team will thank you!

Oracle AI Database 23.26.0 developer features include QUALIFY clause GraphQL Table Function for SQL SQL Objects and Collections in MLE JavaScript PL/SQL RESETTABLE clause to avoid ORA-04068: existing state of packages has been discarded @gvenzl.bsky.social

As others have pointed out we’re mostly blogging to train LLMs, aren’t we? I see very few visitors on my site these days. On the other hand I use the blog mostly to remind myself I’ve solved a certain problem … so all in all, it’s not too bad 😂 And I hasten to add that no AI is involved in writing

🚀 Updated Article Alert! 🚀 Exciting news for all #orclAPEX developers 🧑‍💻 I've just updated my article "Do It Yourself: Updated Developer Playground for Oracle 26ai APEX 24.2 & ORDS" now including #26ai! medium.com/@sonja.meyer... #Developers #TechUpdate

🚀 New blog post! Column-level annotations on Oracle views — a simple way to add meaningful metadata to your DB objects. Why it matters, how it works, and example syntax you can use 👇 🔗 martincarstenbach.com/2025/11/24/c...

Kind of an achievement, at least for me. I definitely wouldn't call myself a Java developer, yet today I learned how to create multi-module Maven projects. And to my big surprise, it all _works_ 😊

There were quite a few talks about AI during #DOAG2025 already. Later today Sonja Meyer and I will add another one to the list where we look very closely at LLMs, MCP Servers and how to use them effectively for APEX development. Includes databases and CI/CD. See you at 17:30!

Talk three of five completed 👍… I honestly didn’t expect such a turnout for my #DOAG2025 session covering how to “automate all the things”. I had a lot of fun demoing Terraform, Ansible, and Oracle REST Data Service Lifecycle Management. Thanks to everyone who came anf your feedback 🙏

Well that was unexpected- standing room only … thank you all for coming to my talk! I had a lot of fun and as I said, if you have any questions, ideas and suggestions hit me up 🤙 #DOAG2025

Ready for day one of three at #DOAG2025. If you care about software development you can see me present about that exact topic at 4pm. I’m flying the APEX colours today since I’m presenting about AI assisted low-code development at lunch 🫣 together with Sonja Meyer.

#DB2026: Der Call for Papers für die DOAG 2026 Datenbank mit Cloud Infrastructure ist jetzt geöffnet und läuft bis zum 19. Januar 2026. Reicht euren Beitrag zu den Streams "Datenbank" und "Cloud Infrastructure" ein und gestaltet das Programm mit. ➡️ scomp.ly/953Pr5Y #Datenbank #CloudInfrastructure

Did you ever play Minecraft? The soundtrack is awesome to listen to when working. Totally helping me to calm down when I’m feeling like I’m too slow getting stuff done. Whoever created it, thank you 🙏 By the way, if you haven’t played Minecraft yet, you should give it a try 😂

The sheer horror that is looking at the demos you created 2 months ago with all the best intentions but lacking any notes and other hints how to use them 😖

#codetalks2025 coming to a close. It has been a blast, I learned a lot during these days and had a great time. Hoping to be back next year 🤞

Day one of #codetalks2025 is about to begin. I’m excited to be part of the agenda, it’s super cool to be here. Today’s session is about Low Code, CI/CD, databases and how MCP and AI can add value. Care to join us at 11:00 in cinema 2?

One more post before October wraps up 🎃 The team got an interesting nut to crack: can you pass JSON PL/SQL types to MLE/JavaScript — and back? ✅ Absolutely, you can! Here’s how 👉 martincarstenbach.com/2025/10/29/p... Have fun exploring! 🚀

📚 New Reading List is out! This week, we take a closer look at #Oracle #Database#Oraclecapabilities with a bit of #Oracle #Cloud Infrastructure in the mix. Happy reading!

This is what I call a productive month of blogging…

🚀 Oracle AI Database 26 has been released, and it’s packed with exciting updates. One of the highlights is what’s new in Multilingual Engine. Until now, passing PL/SQL Abstract Data Types between PL/SQL and JavaScript wasn’t possible — but that’s changed! 👉 martincarstenbach.com/2025/10/28/w...

In the multitenant architecture in Oracle AI Database, the container database is essential. If you create it the right way, you can avoid some difficulties later on. Here's my recommendation for creating container databases.

It’s the little things sometimes 🙏 Like spinning up Oracle AI Database Free in a container and actually seeing recent improvements in action. Also, SQLcl 25.3.0 fixed that overflow bug in the CLI — a much cleaner appearence as a result! Loving these quiet wins. 💡 #Oracle #DevLife

Today I revisited a 4yo post on one of SQLcl’s underrated features: autotrace — shows full session stats for a SQL statement (way beyond SQL*Plus). Still works in latest release. Updated prereqs too. More details here 🔗 martincarstenbach.com/2021/06/10/s... #Oracle #SQLcl #performance #IKYK

Java devs, please instrument your code 🧠 Have you ever struggled tracing SQL back to the app? Use setClientInfo(...) to add meaningful metadata to your JDBC queries. It makes tracing and perf debugging way easier. New blog post with real code & tips: 🔗 martincarstenbach.com/2025/10/16/j...

Sometimes git status is all you need, but on occasion you want to see _all_ the untracked files, especially if they are hiding in a sub-directory. git status --untracked-files=all or git status -uall is your friend.

I've been thinking about adding a Troubleshooting MLE/JavaScript chapter to the JavaScript Developer's Guide. I fleshed out one of the drafts today concerning invoker rights/definer rights. The principles apply to MLE just as they do with PL/SQL. Result: martincarstenbach.com/2025/10/15/o...

Today I was <n> years old when I wrote my first Spring Boot application using JPA/Hibernate and instrumented it via Open Telemetry. I see spans in Zipkin! I probably should be a little less excited but it was too much fun not to be 🥳

Wie verändert AI die Arbeit mit der Oracle Datenbank? Darüber sprechen wir beim nächsten DevTalk am Do. 16.10. – offen und praxisnah. Mit @martindba.bsky.social (Oracle) & @oraesque.bsky.social 17–18 Uhr, online & ohne Voranmeldung! 👉 meine.doag.org/event/id.939... #DOAGDevs #DevTalk #AI #KI

Convert #JSON to rows & columns with JSON_Table But if there are errors extracting a field, by default, Oracle Database sets its value to null @martindba.bsky.social shows how to force an error instead in 23ai with ALTER SESSION SET JSON_BEHAVIOR="ON_ERROR:ERROR"

I was today years old<an undisclosed number of years old> when I started protecting my default branch on GitHub for my side projects. I hope to avoid silly problems like the one yesterday this way …

🚀 New post: Using SQLcl Projects When Your Production Branch Isn’t ‘main’ 🚀 Ran into a configuration issue preparing a demo using a non-standard default branch name. Luckily, the fix is easy. Full write-up + example here: 👉 martincarstenbach.com/2025/10/08/s... #Oracle #DevOps #CICD

SQL Developer for VSCode just got a major upgrade! 🚀 New feature highlight: Post-Execution Debugging — step back through JavaScript in a graphical debugger 🔍 I break it down + how to set it up: 🔗 martincarstenbach.com/2025/10/07/i...

When creating REST APIs what’s your typical response for retrieving data. I quite like the idea in GraphQL where you get an object containing both data and errors - both can be empty. { data: […], error: […] } What do you guys do? It’s JSON, though, isn’t it?

Listening to something more energetic than me this morning to help me finish those slides…. it’s a great, fun game, too, by the way

🔧 Life Hack: you don’t need an external service to generate QR-codes. APEX can do this for you 🤯 In this article I share how I created a QR-code in PL/SQL for use in an upcoming presentation 🖥️ APEX is so much more than a low code platform 🤩 🔗 martincarstenbach.com/2025/10/01/l...

🚀 Found out I needed to resize the root filesystem on my OCI VM while preparing for an upcoming conference. Thankfully it used LVM, so I wrote an Ansible playbook to automate it 🙌 Took me a minute to do, but saved lots of time since. 🔧 Here's how I did it: martincarstenbach.com/2025/09/30/u...
