RMAN speaks a bit more to you since 19.25 Not a big deal - but Samo has brought this to my attention. And the RMAN development and PM team was happy to help and shed some light here. But one after another - what actually is the topic here? Well, RMAN speaks a bit more to you since 19.25 - which…

A lot of people are ready to have some fun upgrading Oracle Databases to 23ai at Oracle DatabaseWorld: Multicloud AI Edition - NY

Awesome #Oracle #Database customer crowd today in Utrecht in the Netherlands for our Advanced Real World Upgrade and Migration Workshop to #19c and #23ai with @dohdatabase.com #OracleDBAsRunTheWorld is not just a slogan - it's absolutely true, fact and reality.

I'm speaking at Oracle DatabaseWorld: Multicloud AI Edition May 7, 2025 at Convene 360 Madison Avenue, New York City If you are there, feel free to stop by and say hi! www.oracle.com/database/dat...

DST Time Zone Patches missing in 23ai Release Updates We work right now with a number of customers going live or being live on Oracle Database 23ai already. And tomorrow will be the release date for the quarterly Release Update, in this case for Oracle Database 23.8.0. But you should be aware of…

New interesting underscores for more than 255 _FIX_CONTROLs I keep saying this - we have the best and most skilled customers. Christian Klose from my Franconian home region contacted me via LinkedIn and asked for some assistance with an SR. I confess, I replied way too late (information overflow).…

DBMS_OPTIM_BUNDLE and the standby database? I could have sworn that I had blogged about it. Aleksey had a comment on the blog and I could not find the answer. But I knew that I had discussed this topic with several people in email already. Maybe it has fallen off my long list of future blog posts.…

DB_LOST_WRITE_PROTECT default change in RU 19.26.0 ORAdiff is an amazing tool I use at least once a day. And if you did the same before applying 19.26.0 or moving from 19.25.0 to 19.27.0, you may have spotted this change as well. There is a DB_LOST_WRITE_PROTECT default change in RU 19.26.0. What…

OCI 2025 certs: renewed and done ✅ Time for the Oracle Database 23ai OCP—because who needs free time anyway? :)

For me, this is the toughest OCI certification. Maybe it’s because I’m not a "networking" person, but I still feel the questions are much more difficult than other OCI certifications. This time, I cleared it in two attempts. Last time (2023), it took three.

Small Pages not allowed for SGA from 19.27 and newer on Exadata Having good friends in Oracle is key. And honestly one of the best things in my role. Philippe Fierens, product manager for Oracle's Fleet Patching and Provisioning mailed me yesterday night sharing that there an interesting change…

If you enjoy low-code development and have some free time, check out this free Oracle APEX certification—it's available at no cost until May 15. I tried it last night, and the exam is very well designed! blogs.oracle.com/apex/post/be...

This year, I finished them early! Completed all three hands-on OCI exams. Surprisingly, I scored 100% on the Security exam — totally unexpected, especially since I spent the first hour thinking I was going to fail!

I look forward to seeing you there.

Remember ORA-39405 with impdp? There is a fix for it Remember my blog post about time zone problems during import from one year ago? When you try to import into an Oracle database and your source database you exported from had a higher time zone (DST) patch level than the target, the impdp failed…

When you patch your Oracle Database, it's important to get it right to avoid downtime. Sharpen your skills in our hands-on lab. It's better to fail in our lab, than in production.

Upgrading a Base Database Service is easy—just press the button. But what happens underneath the hood, and where can you find all the details?

Took a while, but all three OCI hands-on exams are finally done! :)

This one was hard! I've been taking this exam since 2019, and there’s one question that appears every time. I still take a lot of time to figure out the answer.

It's better to fail in our lab than in production! www.youtube.com/watch?v=ntP0...
