What is an Anti-Corruption Layer in the Database and When Do You Need It? Without an Anti-Corruption-Layer (ACL), direct database table access leads to tight coupling, increased risk of breakage on schema changes…

When integrating systems, we often talk about anti-corruption layers in application code. But what about the database layer?

Bigger connection pool = faster app?

That's one of the most common myths in backend dev.

Join our webinar and learn how to actually size your Oracle connection pool — with math, not guesswork.

Database management is more than persistence.

Beyond persistence, a DBMS also provides access rights (GRANT), schema enforcement (types, constaints), schema evolution (ALTER), concurrency control (TX isolation, deferred constraints), a query language…

Persistence is simple, DB managemant is hard.

Expand and Contract Method for Database Changes The Expand and Contract pattern is an iterative, backwards-compatible technique to apply database changes in small, safe steps.

The Expand/Contract Method is a tool for safe database changes

Expand: add new schema elements
Migrate: move code to these
Contract: remove old elements

@jasminfluri.bsky.social discusses using it to

Rename a column
Split a table
Change the data type of a column

Stonebreaker's article on database decay (ieeexplore.ieee.org/document/784...) made me write a snippet about safe database refactoring and the expand-contract method. ✒️

We have approval to release Oracle AI Database 26ai on non-Oracle hardware for deployment on-premises!

The wait is (nearly) over!

Oracle AI Database 26ai EE for Linux x86-64 will be released on premises in the next RU (23.26.1), due January 2026

Read full details at blogs.oracle.com/database/ora...

Finally … Oracle AI Database 26ai is going to be available on non-Oracle hardware Many of you have read my blog post from October during Oracle AI World in Las Vegas about Oracle AI Database 26ai replacing Oracle Database 23ai. But the main question remained: When is it available on-prem on non-Oracle hardware? It's December now, and Christmas is coming soon, it is time for presents. Yes, finally ... Oracle AI Database 26ai is going to be available on non-Oracle hardware…

SQL assertions syntax

Multi row/multi constraint example “controllers must work in finance”

Multi row/multi table constraints “Can’t earn more than your manager” “Can’t have multiple presidents” “Must be a president”

Coming in Oracle AI Database

#SQL assertions

These enable you to create cross row, cross table constraints with SQL standard syntax

CREATE ASSERTION … CHECK (
[ NOT ] EXISTS ( <query> )
)

Database Rollbacks in CI/CD: Strategies and Pitfalls Database rollbacks would be incredibly valuable and essential if we want quick fixes for failed deployments. But they are rarely feasible.

Database deployments can fail

But rolling back schema changes is tricky - so plan them

Versioned Migrations with Reversible Scripts
Backups before Changes
Immutable Migrations & Forward Fixes
Restore Points & Flashbacks

Last week, at pgconf.eu I got the best feedback ever. I was told:
"You saved my life! Since I know Merise there's not a week where I don't use it and show it to my coworkers!"

Here are the slides:
l_avrot.gitlab.io/slides/meris...

Reading List – October 2025 #4 📰 How to write a custom tracer for Oracle Database JDBC - Anders Swanson demonstrates the new Oracle Database JDBC OpenTelemetry provider capabilities 📰 tabhisthybrid.sql: Display Oracle hybrid histograms and filter cardinality estimates - Tanel Poder has a new script for Oracle Database hybrid histograms 📰 Using Oracle Database Free in your devcontainer and GitHub Codespaces - Martin Bach shows you how to use Oracle Database Free in GitHub Codespaces&hellip;

📚 New Reading List is out!

This week, we take a closer look at #Oracle #Database capabilities with a bit of #Oracle #Cloud Infrastructure in the mix.

Happy reading!

It will fit into one of the bottle cages, I'm sure 😁😅

So thankful to be part of this community! 🙏
@oracleace.bsky.social swag arrived just in time for the moody central european autumn weather. 🍂🍁 🫶

Since I couldn't find any benchmarks on the topic, I'm not sure about it. Something to validate...

A short summary of the differences between UUIDv4 and #UUIDv7 and an idea how it could be implemented in #Oracle #database. A UUID datatype would be nice 😉.

I felt like writing a blog post —a little write-up on why fixing failed #database deployments is challenging.
Spoiler: The part about undo-scripts might feel like a rant, probably because it is. 🙃
