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...

You can define your own inline JavaScript code delimiters in Oracle MLE — even emojis (💥). A small but useful detail I explored after a great question from @oyvindisene.bsky.social at #POUG2025. Blog post 👉 martincarstenbach.com/2025/09/08/i... #oracle #MLE #javascript

🛠️ Just updated: “Implementing DevOps Principles with Oracle Database” Asked devs: Are you using AI in your CI pipeline? 🧠 Most said: AI happens before the pipeline, not during. No clear standard—yet. 📄 Dive into the brief: www.oracle.com/a/ocom/docs/... #DevOps #CICD #Oracle #AI_In_DevOps

I’m so in love with `git stash` and `git stash pop`. So convenient for people like me who occasionally get off track while multitasking 🫣

🚀 Question to the Tech Community 💻 Are you integrating AI-powered tools into your DevOps CI/CD pipeline? 🤖 Do you believe they truly belong in the pipeline, or are they better suited for development and local testing only? I’d love to hear your thoughts! 💬

🔍 Seeing NULL from JSON_TABLE in Oracle even when the JSON field you query isn't null? It might be due to very long text values. Here's how to debug & fix it 👉 martincarstenbach.com/2025/08/07/w... #OracleDB #JSON #SQLTips

🚨 Oracle DB 23ai Release Update 9 is here! 🚨 🆕 23.9 introduces GROUP BY ALL-no more errors for missing columns in GROUP BY! Super awesome for ASH queries 😀 📖 Details: martincarstenbach.com/2025/08/06/g... 👉 Try it now in Autonomous DB or any other 23.9 db #Oracle23ai #OracleDB #SQL

Recently I needed to understand a problem related to starting an Oracle REST Data Services (ORDS) container image in my lab. It ran into an error and aborted 😥 Turned out it was an oversight on my part but the troubleshooting story might still be useful for you. martincarstenbach.com/2025/08/01/t...

This is one of the reasons why I’m blogging: to avoid having to reinvent the wheel. Created a cloud VM today with a bunch of block devices and attached them automatically using Terraform. Guaranteed device name persistence 👍 martincarstenbach.com/2020/12/07/d...

This is a great post showing you how to use multiple properties files in SQLcl projects. This trick comes in very handy when you want to deploy your APEX app to multiple environments. blog.neilfernandez.com/sqlcl-projec...

I haven't found a way to use secrets in Docker{-Compose}. Looking for alternatives I came across variable interpolation. In other words, you can use .env files with compose thus making your compose files more secure. Here is a short post how to do that: martincarstenbach.com/2025/07/30/s...

Have you heard about Oracle LiveSQL yet? It's the easiest way to access the Oracle database engine to run SQL, PL/SQL and now JavaScript. The JavaScript part in particular is interesting, and since it's new, I wrote a short blog post about it. martincarstenbach.com/2025/07/29/l...

Oracle Database has added many #SQL features in each RU for 23ai @gvenzl.bsky.social runs through what's new in 23.7 TIME_BUCKET Function Materialized columns DBMS_DEVELOPER.GET_METADATA Call PL/SQL from JavaScript stored procedures Smallfile Tablespace Shrink

I have been eying these for a while and finally gave in. I’m a proud owner of a developer keyboard now 😀

Ever since publishing “Implementing DevOps principles with Oracle Database” I wanted to create a sample repository complete with a CI pipeline. Looks like I’m getting closer to implementing it in GitHub Actions. Only a few more things to add and I can hit the “change visibility” button 😁

I wrote a short post about a cool enhancement in Oracle REST Data Services release 25.2 concerning console.log() output in JavaScript handlers. It's now much easier to identify output. Here are all the details: martincarstenbach.com/2025/07/10/b...

I have been blogging for a long time, mostly so I don't forget how to do things. Today was one of these days where that came in handy :) I'm preparing for my #POUG talk and was quite happy to find my intro to bpftrace martincarstenbach.com/2021/07/12/g... Let's see how all of this changed since 2021

A little while ago I wrote a post about Podman Secrets and how to use them with Oracle Database 23ai Free. This post has enjoyed a lot of popularity and that was enough to merit a big update. Each and every component is now current: martincarstenbach.com/2022/12/19/p...

This has got to be the most updated article on my blog: martincarstenbach.com/2024/01/11/f... Besides the MLE/JavaScript aspect it's a great showcase for the power of containers. Want to create an APEX environment with 1 command? Head over to the blog to see how to do that

Today is "late spring cleaning day": I updated all blog posts containing compose files for Oracle Database 23ai Free and ORDS/APEX. Moved the code to GitHub because it's easier to maintain over there. If you are interested in a hands-free-APEX installation here's the repo: github.com/martincarste...

I had the privilege to present about CI/CD and relational databases during #Thementage25 (www.ittage.informatik-aktuell.de/thementage.h...) I promised I'd polish my demo and blog about it, and that's what I did today. Here's to SQLcl project and Oracle 23ai: martincarstenbach.com/2025/06/25/t...
