How to relink Oracle for Enterprise or Standard Edition?

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 …

Oracle Database 19c on Arm platform is available

I knew it would come – but we couldn’t tell you. And there were some rumors for a longer time. Anyhow, last week at the end of June 2023 Oracle Database 19c on Arm platform is available for download and in the Oracle Cloud. In case you wonder why I write “Arm” – I learned last week that the writing has been changed a while ago from ARM to Arm.

A patch (RU, OJVM, 32-bit) is not available yet – where will I find information?

A longer while ago I wrote a blog post about the topic that a patch (RU, OJVM, 32-bit) is not available yet – where will I find information? But I wrote it too specific. And it is even hard for me to find my older blog post. Since several of you mailed me the past weeks with a variety of questions regarding patch availability I decided to write down my thoughts – but this time in a more generic way. And I hope it is helpful.

Why are patches missing?

At first, I …

Oracle Optimizer Statistics Advisor in Oracle 19c

Christian Pfundtner pointed me to the fact that my old blog post about the Statistics Advisor from 2017 may not be up to date anymore. And he further pointed out that some of his clients still suffer from issues with the tool. Hence, let me refresh the topic with Oracle Optimizer Statistics Advisor in Oracle 19c. And thanks to Christian for the pointers.

 

Overview

At first, I won’t rewrite the entire blog post but instead focus on recent findings. Therefore, you may please want to read my previous blog post about the …

ORA-13516 “CATPROC not valid” during datapatch or autoupgrade to 19.18.0

I thought I could relax this week using my leftover vacation days from 2022. But this issue is triggering me since some of you mailed me already. Maybe this blog post can prevent others from being trapped by this issue: ORA-13516 “CATPROC not valid” during datapatch or autoupgrade to 19.18.0. And as a prolog, you will NOT see the below issue when you started your database in NORMAL mode for the execution of datapatch.

 

What is the symptom?

Regardless of whether you patch to Oracle Database RU 19.18.0 manually or with …

Hide and Seek with RU 19.18.0

One and a half weeks ago we released the Database and Grid Infrastructure Release Updates (RU) 19.18.0. You could read on the blog how to apply it, and you could read also about an alert. So far, all was more or less transparent but apparently sort of an Hide and Seek with RU 19.18.0 has happened. So let me shed some light.

Heads Up!

I am just the messenger trying to bring some light into the topic. Neither is our team responsible nor do we have any sort of control on this process. I …

Binary patching is slow because of the inventory

The headline of this blog post may sound a bit cryptic: Binary patching is slow because of the inventory. But actually this seems to be one of the main causes when your binary patching gets slower and slower with every patch you apply.

The more you patch, the worse it gets

Well, this is a tough headline. But you may have read my blog posts about my quarterly patching experience. It actually started with the July 2021 RU in my 19c environment when I wrote:

At least in my environment, both checks with the

Oracle Database 12.2.0.1 and GI are certified on OL8 and RHEL8

No worries, this isn’t a blog post from the vault. And I haven’t accidentally published something from the past just today. It is real. Oracle Database 12.2.0.1 and GI are certified on OL8 and RHEL8.

Thanks to my colleagues and a large customer in the UK, I received an email asking whether I have seen this information already on MOS. I haven’t. I knew that there were discussions but I had no actual date for the 12.2.0.1 certification on OL8 on my radar.

Virtual Classroom Seminar 12: Migrating Very Large Databases on Dec 9, 2021

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.

Should you enable _fix_controls with DBMS_OPTIM_BUNDLE?

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:

Workaround for sdoloadj.sql errors with Datapatch in 19.9.0 and 19.10.0

The other week a customer from my hometown alerted me about an issue they saw when applying the 19.9.0 RU. A long sequence of errors in the datapatch run, all of them signaled from sdoloadj.sql. They opened an SR. And Support had an – understandable – recommendation the customer didn’t want to implement: Install JAVAVM. But thanks to my PM mate, Hans Viehmann (Mr Spatial), here is a simple Workaround for sdoloadj.sql errors with Datapatch in 19.9.0 and 19.10.0. And it may even apply to later releases, too.

Check your Unified Auditing Policies after upgrading to Oracle 19c

This may become a longer blog post. One of the customers I work with for many years contacted me a few weeks ago. After upgrade to 19c, it looked like as if some Unified Auditing Policies weren’t correct anymore. It started as a tiny issue, but thanks to the customer who analyzed down to the bones, it seems to be bigger than we thought at the beginning. So you may Check your Unified Auditing Policies after upgrading to Oracle 19c as well.

Which database version can be used with Grid Infrastructure 19c?

This will be a very short blog post today. But a colleague asked me this question just a few minutes ago: Which database version can be used with Grid Infrastructure 19c? And I realized that I neither put it on the blog yet nor did I bookmark it. But I answered this question several times already.

Which database version can be used with Grid Infrastructure 19c?

There are 4 sources I did check:

  • MOS Notes on MyOracle Support
  • Oracle Documentation
  • Certification Information on MyOracle Support
  • Database Upgrade Blog

Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com

You may have realized that you will find mostly on-prem database upgrade and migration topics covered on my blog. Which doesn’t mean that you can’t use most of these techniques to migrate to the cloud either. But it’s really hard to write about everything in full detail. Hence, today I’d like to introduce you to Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com. And no, I was never a fan of this American boyband from the 80s and 90s 😉

Does your GI RU/RUR patch level has to match your database’s?

A long while ago I blogged about whether you should keep your patch versions between Grid Infrastructure and Databases Homes in synch, or not. And today, Daniel dropped me a note mentioning that this old blog post may need an update for 18c/19c. He’s right. And as I’ve had trouble finding my old blog post, I title this one a bit more obvious: Does your GI RU/RUR patch level has to match your database’s?

Do you need to license Java for AutoUpgrade?

Do we offer patched Gold Images already?

Internally we can use a Gold Image service at Oracle. I can download a zip with 19.6.0 included. But externally for you as customers, the download of 19.6.0 required that you download 19.3.0 at first, then apply 19.6.0 on top of it. But a day ago, a tweet by my Belgium friend Philippe Fierens caught my attention. Do we offer patched Gold Images already?

AutoUpgrade Tips: Running two (or more) sessions in parallel

Our intention with the AutoUpgrade as the single tool to upgrade your databases was initially: You have one big config file for your databases. And you will use this file to upgrade your databases unattended. Ideally you run an “analyze” at first, then you schedule a “deploy” for overnight or the next weekend or whenever it is convenient for you. But sometimes people have different needs. In this particular case several people asked whether you can run multiple AutoUpgrade tools in parallel on the same server. Hence, I’d like to explain the first of more AutoUpgrade …
