Oracle AI Database 26ai replaces Oracle Database 23ai

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…

How long can I request a backport for Oracle Database RUs?

Posted on December 2, 2024 by Patch Recommendation Release Schedule 0

I’ve had this topic on my “to write about” list for a long time. But somehow it felt through the cracks. Especially in relation to the recently announced extension of the Oracle Database 19c Premier and Extended Support periods it may be useful if you are aware of this policy since you may ask yourself: How long can I request a backport for Oracle Database RUs?

What is a backport?

As we explain in Virtual Classroom Seminar – Episode 17: From SR to Patch – Insights into the Oracle Database Development process we fix …

How to relink Oracle for Enterprise or Standard Edition?

Posted on February 2, 2024 by Installation 14

What a weird blog post. But let me explain briefly the motivation for my Friday article. As you know, the blog serves also as my brain dump. And whenever I try something out I know I may need later again, I dump it here. Certainly, some LLM will pick up the information and spill it out later when you ask the interface about How to relink Oracle for Enterprise or Standard Edition?

From Enterprise to Standard Edition?

Of course, you can. But I had no idea how to when Philippe Fierens, the PM …

At first, Happy New Year everybody. There was silence on the blog for some weeks but I took an extended longer time off.

Applying the MRP from December 2022 to Oracle 19c

Posted on December 21, 2022 by Patch Recommendation 16

Well, couldn’t there be a nicer pre-Christmas present than the December 2022 Monthly Recommended Patches (MRP)? You know, I’m just kidding. But since I received the first questions from customers – and before I send an email internally – I wanted to try out Applying the MRP from December 2022 to Oracle 19c.

Patching all my environments with the October 2022 Bundle Patches

Posted on November 9, 2022 by Patch Recommendation 56

Oh yes, it is patching time (again). And this time I somehow missed the slot since the quarterly critical patch updates got released right during Oracle Cloud World. Since I didn’t want to stretch the hotel WiFi too much – and since I wouldn’t have had enough time to install and write-up this blog post, I do it now with a week of delay. So as usual every quarter, follow me for patching all my environments with the October 2022 Bundle Patches.

As usual, an important annotation upfront: I patch in-place due to …

Migrating Flashback Data Archive (FDA) tables

Posted on April 8, 2022 by Export - Import 17

This morning I received an email question from a customer asking whether there is support for the Migrating Flashback Data Archive (FDA) tables in Oracle 19c. And since this is not the first time I received this question, I thought it may be good to have a blog post about it.

What is Flashback Data Archive (FDA)?

Well, google it. Actually I was looking for a link in our documentation but to my surprise I found the usual suspects such as Tim Hall’s excellent oracle-base page – but not much in our own doc …

AutoUpgrade 2.0 has been released – and got reuploaded

Posted on March 25, 2022 by AutoUpgrade 42

Many of you have used AutoUpgrade for your database upgrades already. Just a few days ago I received some almost enthusiastic comments which made me very very happy. And if you thought it can’t get any better, no worries: AutoUpgrade 2.0 has been released – and got reuploaded.

Why AutoUpgrade 2.0?

As you know, we don’t do marketing but just talk tech. But you may have also recognized that we slowed down in our agile release cycle for AutoUpgrade. The simple reason for this long period of silence was that we’ve had a …

After patching, Spatial Index creation fails with ORA-13249

Posted on August 4, 2021 by Flaws and Pitfalls 11

Thanks again to Peter Lehmann from T-Systems for highlighting this issue to me. After patching, Spatial Index creation fails with ORA-13249. And Peter’s customer was quite worried. But see what may have caused this, and how we fixed it.

After patching, Spatial Index Creation Fails with ORA-13249

What happened?

Peter patched a system from 19.10.0 to 19.11.0. This database has undergone an upgrade from 12.2.0.1 to 19.7.0 before, then got patched to 19.9.0 before. The database has the Oracle Locator only but no Spatial installed. The patching including datapatch worked fine. All seemed to be good. Until the customer tried to …

ORA-1555 won’t get reported into alert.log anymore since 19.4.0

Posted on September 10, 2020 by Behavior Change 8

Many thanks to a German customer for showing me this tiny behavior change with Oracle Database RU 19.4.0. From this RU on the well known ORA-1555 won’t get reported into alert.log anymore since 19.4.0. But if you still like to see the “snapshot too old” error, then you can use a workaround.

Why has this been changed?

Actually this is something I don’t understand completely. It may be just a side effect. Unpublished fix bug 29424999 – DUMP MINIMAL DIAGNOSTICS BY DEFAULT IN CASE OF ORA-01555 IN ADW/ATP ENV has been …

Config file for AutoUpgrade 19c – Advanced options

Posted on June 28, 2019 by AutoUpgrade 32

Config file for AutoUpgrade 19c – Advanced optionsIn the previous blog post I explained how to create a config file for the AutoUpgrde utility. And now I’d like to show how you can use some important advanced options to have the AutoUpgrade utility do or skip specific tasks. Read about how you can tweak the config file for AutoUpgrade 19c – Advanced options.

I will describe only the most important advanced parameters which I think can be very useful in your environments. Of course, there are many more as you can see in the Database Upgrade Guide.

Oracle Database 18c for AIX, HP-UX and zLinux available

Posted on November 19, 2018 by Release Schedule 4

I rarely blog twice a day – but this message is the one a good number of people have waited for quite a while. Oracle Database 18c for AIX, HP-UX and zLinux available for download from eDelivery as of now. The software is not on OTN or oracle.com yet in the usual download section. I’m blindly guessing that it will be there soon, maybe tonight already.

Current Support Status for Oracle Database Releases

Posted on October 16, 2018 by Release Schedule 11

Yesterday a former colleague from the UK pointed me to a very old blog post about the fact that no patches will be produced for Oracle 11.2.0.3 anymore. Which is a true fact. But it reminded me that it may be time for an overview on the current support status for Oracle database releases as of October 2018.

Video: The New Database Release and Patching Model

Posted on July 10, 2018 by Video / Viewlet 8

Video: The New Database Release and Patching ModelThe last Office Hours I’ve run about the New Release and Patching Model didn’t go very well technically. I’ve had screen/display issues. And Steven Feuerstein tried to save the best parts – but despite Steven’s awesome work neither him nor I did really like the result. So I decided that it may be better to record a Video: The New Database Release and Patching Model again (which I actually planned for quite a while already anyway.

What does DEPRECATED mean? And DESUPPORTED?

Posted on March 23, 2016 by Deprecated / Desupported 6

There’s sometimes a misunderstanding about what we mean with the term DEPRECATED? And what is the difference to DESUPPORTED? Actually there’s a full chapter in the Database Upgrade Guide listing deprecated and desupported features.

Deprecated

Especially this message puzzled a lot of customers stating that the non-CDB architecture is deprecated in Oracle Database 12c.

In the Database Upgrade Guide we clearly explain what deprecated means:

“By deprecate, we mean that the feature is no longer being enhanced but is still supported“

So for you it means just be …

It’s always the Optimizer, isn’t it?! – Part 1

Posted on October 19, 2011 by Optimizer Oracle Database 11g 0

Wouldn’t you agree?

My colleagues from the Optimizer Development might forgive me but a lot of people would say: “Everything went fine after upgrade – except for those tiny 3 queries!”. And I know, you have tested a lot. I’d like to tell you about a few issues we’ve seen post upgrade with 11.2.0.2.

  1. You have captured your plans in Oracle 10.2 pre-upgrade.
  2. You have moved these plans from your SQL Tuning Set into the SQL Plan Baseline in Oracle 11.2.
  3. But the optimizer doesn’t pick them although you have:
    (a) ACCEPTED and
    (b) FIXED them.

Why?
