Oh … it’s just a few weeks left until Oracle Cloud World 2022 will start on Oct 17, 2022 in Las Vegas. If you have some final doubts whether you should go or not, let me tell you that it’s like Oracle Open World just under a different name. And in a different place. But with the same cool people and many great talks. Take the chance to meet the developers, their managers and the product managers behind the features you daily use – or miss. We’ll be there – and this is YOUR chance now to sign up for …Continue reading...
Funny, I was traveling recently with RAC PM Anil Nair – but he forgot to tell me that this cool story has been published just a few days before we took of for YATRA 2022 to India: Intel uses AutoUpgrade to upgrade from Oracle 126.96.36.199 to 19c.
What’s the story?
Gagan Singh, Enterprise Architect at Intel, shared it with me last week. The goal was to upgrade from Oracle 188.8.131.52 to Oracle 19c with the least amount of downtime to minimize the impact on factory operations. Oracle ACS and the RAC PM team …Continue reading...
Well, there are still 80+ comments I need to answer and reply to on the blog. So please be patient – nothing gets deleted or ignored. But it happens that a topic crosses my inbox, and I need to blog about it right now. Today, it is a case where a customer asked me for advice, and mentioned on the side that they are going to 19.6.0 in OCI. In this relation I’d like to explain why Certifying an application on a specific RU- only is wrong.
What’s the story?
At first, …Continue reading...
It’s time for a Monday morning rant. I receive more and more questions which all start similar. “My customer is on Oracle 11g and/or 12c, and want to know whether the next long term support release …“. Now let me clarify Why you simply can’t upgrade from Oracle 11g or 12c to Oracle 23c. And why you MUST upgrade to Oracle Database 19c.
What is the intention?
After a lot of discussions across many regions, especially in JAPAC during the past weeks I realized that there is a reason for all …Continue reading...

I remember, I have a blog. Forgive me that I don’t write a lot at the moment even though I still have a long queue of “future posts to write”. It is just too busy, and I was away for almost two full weeks in June as well. But let me briefly drop information on an issue I learned about recently. It just affects your when Upgrade from 184.108.40.206 to 19c with Label Security Policies. All other readers may simply ignore this blog post.
You are using Oracle Label Security, and …Continue reading...
If you finally want to see all the cool new features of AutoUpgrade 2.0 (the 2.0 is just a marker we use to say: We improved it significantly!), the please sign up to Virtual Classroom Seminar #14: AutoUpgrade 2.0 on May 5, 2022.
What are we going to talk about?
The development team invested a lot of resources to implement some of the most wanted features in AutoUpgrade. Spoiler: One feature is still missing but will be released very soon. In this Thursday’s Virtual Classroom Seminar we will talk about:
- PDB and non-CDB
This will be a short blog post but since I received a number of messages yesterday after I published my usual Patching all my environments with the April 2022 Patch Bundles blog post I need to clarify a few things regarding Oracle Database 220.127.116.11 – End of Support and Patch Bundles.
Premier Support for Oracle 18.104.22.168
If you remember this, the Premier Support period for Oracle 22.214.171.124 ended on November 30, 2020.
Limited Error Correction Support for Oracle 126.96.36.199
Since many of you were still on Oracle 188.8.131.52 when the end of Premier Support …Continue reading...
Oracle Database 11g? In 2022? Yes, I know – and you know too – there are Oracle 11g databases out there in production. And blindly I’d say: Too many. Of course, we are the “upgrade guys” trying to convince you to move to Oracle Database 19c. And I bet, for each of your 11g databases there’s a valid and legit reason why they haven’t upgraded yet. But there is one often neglected technical reason Why you can’t stay on Oracle Database 11g forever. So let me explain this below.
Oracle Database 11g?… Continue reading...
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 …Continue reading...
It looks to me that every possible event in 2021 happens in October/November/December 2021. No complaint from my side – but just in case you wonder about so little update activity on our blogs since weeks. We are just so busy in delivering virtual seminars. Which is good – but it requires lots of effort on our side as we want to deliver decent quality and real tech content. And now, since the year is almost at its end, it is time for our final Virtual Classroom Seminar 12: Migrating Very Large Databases on Dec 9, 2021 this year.… Continue reading...
No idea what you should do this week’s Thursday morning at 10:00h CET? No worries, I know what you should do. You’ll attend our 10th Virtual Classroom Seminar: How Low Can You Go? Zero Downtime Operations on Oct 21, 2021, part of our Upgrade to Oracle Database 19c series.
Virtual Classroom Seminars?
It will be the 10th Episode of our Virtual Classroom Seminar series. If you attend one or many before, you know that we don’t do marketing but transport only tech content. And always things we tried out by ourselves beforehand or used them already in many …Continue reading...
As you know, this blog is also my brain dump about Oracle topics. Since this one happened yesterday, mostly at night with the help of my team mates and the Java team, I’d like to write it down into this blog post: Upgrading a PDB with Java may result in ORA-7445 joevm_invokevirtual() as it is still fresh and may affect you as well. If you don’t have PDBs, if you don’t have Java (or JVM) in it or if you upgraded already to Oracle Database 19c, you can stop reading now.
What… Continue reading...
As I wrote before, the release you should upgrade to is clearly Oracle Database 19c. Unless you need to use one of the new features in Oracle 21c. But as you have seen in the past, some of them get backported to 19c as well. Still, in case you can’t resists or you love upgrades as much as we do, the question may be: Which releases allow you to upgrade to Oracle Database 21c?
The Database Upgrade Guide for Oracle 21c is your best friend here. Right at the beginning in the first chapter you will find this …Continue reading...
You may have read my previous blog post about Upgrading a non-CDB to Oracle Database 21c. And I referred to a potential Pitfall: Upgrade to 21c fails when ORDIM is present but no SDO. In this blog post I would like to explain how to avoid this pitfall beforehand and explain what needs to be done.
What’s the problem?
In my previous blog post I showed you the ideal and normal way. But during my tests I came across an issue I was not aware of – and I simply had no …Continue reading...
Yesterday I wrote about the installation of Oracle Database 21c on Linux. But today it is time for Upgrading to Oracle Database 21c with AutoUpgrade.
You may have heard it already from us and other colleagues, but we can’t repeat it often enough: There is only one recommended tool to upgrade your databases – and this is AutoUpgrade.
In my 21c home, I’m checking the deployed version of AutoUpgrade at first:
[CDB3] oracle@hol:/u01/app/oracle/product/21/rdbms/admin $ java -jar autoupgrade.jar -version build.hash 57ab246 build.version 21.1.3 build.date 2021/04/21 13:32:13 build.max_target_version 21 build.supported_target_versions 12.2,18,19,21 build.type production
Now please …Continue reading...
Today, Paul mailed me asking a question we internally discussed many times in the past weeks: Should you enable _fix_controls with DBMS_OPTIM_BUNDLE? And there is no easy simple answer. But I can give a recommendation based on my experience from many projects.
DBMS_OPTIM_BUNDLE – a quick recap
Just in case you haven’t dealt with DBMS_OPTIM_BUNDLE recently, here is a quick recap.
With below procedure, you can list the available potentially behavior changing optimizer fixes in the current patch bundle – and you can turn them on or off at will:
SQL> set serveroutput on;… Continue reading...
As we often tell you, our Upgrade Development team is working hard to ensure an agile release cycle for AutoUpgrade. And the New version of AutoUpgrade (21.2) is available for download.
How to download?
As usual, you can (and should) always download the most recent version of AutoUpgrade from this MOS Note: 2485457.1. Usually the tool gets refreshed every 6-8 weeks. And the version you will download is guaranteed newer than the one you could get on disk.
The fact the tool has a 21c versioning does not affect 19c upgrades. There …Continue reading...
Many people on the northern hemisphere will escape during July into the summer holidays. But we won’t. Instead, thanks to Sai Penumuru, we will give seven webinars for the aioug. And we are looking forward to talk to you soon at the aioug Webinar Series July 2021: Database Upgrade and Migrations.
When will it happen?
This morning I looked into my calendar. And I realized: Wow, July 2021 is just a few days away. Roy will start with the first session on Friday, July 2. And then myself, Rodrigo, Daniel, Fred and Bill will …Continue reading...
This will be a short but very important blog post for those of you with Exadata systems. Then you should Upgrade to Oracle 19c on Exadata with AutoUpgrade.
Why is this important?
Until a week ago, the database upgrade MyOracle Support (MOS) note showed the process using the DBUA. And we had plenty of customers asking us why AutoUpgrade isn’t mentioned there. Our team worked already with some of you, and we knew that AutoUpgrade works perfectly fine and takes over some manual actions.
But our MAA team wanted a perfect solution. They …Continue reading...
We are thrilled to announce that as of June 7, 2021 we have a new member in our Product Management team: Rodrigo Jorge joins our group as Product Manager for Database Cloud Migrations, Upgrade and Patching. Many of you may know Rodrigo already. He “was” an Oracle ACE Director until June 6, presented at many conferences and user group events – and he has an excellent technical blog. We are really excited to welcome Rodrigo at Oracle.
Who is Rodrigo?
When we launched AutoUpgrade, it could upgrade non-CDBs and CDBs with all PDBs. Soon after, it learned to upgrade a non-CDB and plug it into an existing CDB as a new PDB. And then, as next step, we added Unplug / Plug / Upgrade with AutoUpgrade. In this case you have a PDB (or hopefully more than one), and you’d like to upgrade one or many PDBs by moving them to a new CDB with a higher database version.
As test setup I use our Hands-On Lab.
I will …Continue reading...
Today, I would like to publish only a short blog post with some hints to MyOracle Support (MOS) notes we find quite helpful. The idea of all these notes I will list below is to help you finding the right patches before you upgrade or patch to Oracle 19c. So see our collection of Some very important MOS Notes when you upgrade and patch below.
Why do you need patch bundles?
At first, it is always our recommendation to upgrade to the most recent Release Update (RU). This is currently Oracle 19.11.0 while I’m …Continue reading...
Thanks to Christian Ballweg from Optiz Consulting who brought this issue to my attention. I haven’t seen it before since I haven’t installed it but you may encounter this if you have the Messaging Gateway – Upgrade can’t find mgwu122.sql.
What is the Messaging Gateway?
Actually I steal this from the documentation:

Messaging Gateway enables communication between applications based on non-Oracle messaging systems and Oracle Database Advanced Queuing.
Ernst Leber sent me an email today. He hit an error at a customer upgrading to Oracle 19.9.0 on Exadata with AutoUpgrade. ORA-1422 and ORA-6512 from SYS.DBMS_STATS in Post Upgrade were signaled – and he better flashed back to the Guaranteed Restore Point. He found even a MOS note but still had questions. So time to blog about it in case you hit this error sequence as well.
What happens, and when does it happen?
At first, this is not an AutoUpgrade issue. You may see the same error stack in the post upgrade …Continue reading...
