Posted on March 17, 2026 by AutoUpgrade Single-/Multitenant 4

Sometimes you have different plans for the day. Or, in my case, the day just needs a few extra hours. Today, I received a very interesting question on the blog at first by a customer I know very well. Then we exchanged mails – and I was caught forgetting what I wrote on the blog a longer while ago. The core question is: Does AutoUpgrade support the MOVE option? But there was much more to discuss and figure out as you can read below.

Posted on October 14, 2025 by Oracle AI Database 26ai 55

Larry Ellison announced Oracle AI Database 26ai  today in his keynote at Oracle AI World conference in Las Vegas. And I am pretty certain you may want some clarification on what this means exactly. Therefore, let me clarify the details, and why Oracle AI Database 26ai replaces Oracle Database 23ai.

Oracle AI Database 26ai replaces Oracle Database 23ai

What did Larry Ellison announce?

Larry gave a spoiler already in the Q1 earnings call where he referred to Oracle AI Database instead of Oracle Database. He was clearly emphasizing the AI capabilities of our flagship product. From now on, it will be known as Oracle AI Database…

AutoUpgrade migration to Oracle 23ai Exascale with Refreshable Clones

Posted on June 30, 2025 by AutoUpgrade 0

Those of you who have been to our workshops in the past 3 years know that we promote one feature as the ultimate killer feature for moving to Oracle Database 19c and 23ai: Refreshable Clones. These work not only from PDB to PDB, but magically also with a non-CDB. And our teams works with a good number of customers using exactly this technique to Oracle 23ai. Now, we talked about it. And we blogged about it (see below). But there is a brand-new MOS note out there showcasing an AutoUpgrade migration to Oracle 23ai Exascale with Refreshable Clones.

People do super-cool stuff … AutoUpgrade Composer

One of them is Marcus Vinicius, an Oracle ACE Pro from Brazil who lives in Dallas, TX in the US. And besides being a real wizard he is also a super-nice guy. No idea where all these Brazilian Oracle experts “grow” but I am very proud to have two of the best in the world in our team. But back to Marcus.

Posted on April 22, 2025 by Differences Optimizer Parameters 6

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.

Why don’t you see them in ORAdiff?

As usual, I went to ORAdiff and tried to find out anything about these new _fix_control parameters. But I couldn’t find any indication for what Christian …

Posted on April 17, 2025 by Behavior Change Exadata / ODA Flaws and Pitfalls 12

Philippe Fierens, product manager for Oracle’s Fleet Patching and Provisioning mailed me yesterday night sharing that there is an interesting change coming with Database Release Update 19.27: Small Pages not allowed for SGA from 19.27 and newer on Exadata.

How do find new features in Oracle Release Updates (RUs)?

I know, not everybody is a huge fan of new features in RUs. But how do find new features in Oracle Release Updates (RUs)? Are the listed anywhere? They are, no worries. At least since Oracle Database 19c.

New Features in RUs?

I can already sense that some of you will be tempted to comment and tell me that you don’t like any new features in Oracle Database Release Updates, in short: RUs. But on the other hand there is also something good with it. Rather than waiting for the next full database release …

Looking for support dates for Oracle Middleware, GoldenGate, JDK and more?

Well, after a few wild travel days, this morning I received an email from my ex-VP in my presales days, Günther Stürner, asking whether I have a matrix for Oracle GoldenGate support time frames as we share them about the database in all our slide decks. And I confess, I had no such overview.

Later the day, Günther updated me – he found it and shared it with me, too (thank you!!).
