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 …

MRP3 for Oracle 19.17.0 adds an interesting surprise

You may have read my previous blog posts about MRPs (Monthly Recommended Patches). And today I did a quick check with Rodrigo.

As a teaser, read on to see that MRP3 for Oracle 19.17.0 adds an interesting surprise.

 

How did we find out?

The MRP3 for Oracle Database 19.17.0 got released just a week ago. You can navigate to it via MOS

A change in Oracle 12.2 and 19c with MV Refresh Stats Collection

It’s not easy for me to put the topic into a searchable title for this blog post. The feature or change I will write about today came in actually with Oracle Database 12.2.0.1. But since many of you will move directly from Oracle 11.2.0.4 or 12.1.0.2 to 19c, the Long Term Support release, it may affect you as well. So let me explain a change in Oracle 12.2 and 19c with MV Refresh Stats Collection.

The local Support team asked me a few weeks ago whether I have heard …

Applying the first MRP for Oracle 19.17.0

A few weeks ago I blogged about the fact that we retired the RURs, and instead release the MRPs (Monthly Recommended Patches). In my previous blog post about this topic you’ll find also an FAQ hopefully answering all the questions you may have (had). And now it is mid of November, so I can show you the process of applying the first MRP for Oracle 19.17.0.

 

How do you get access to the MRPs?

At the moment while I write this, you can find the MRPs only in MOS Note: 888.1 -Primary

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.

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 – End of Support and Patch Bundles

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 12.2.0.1 – End of Support and Patch Bundles.

Premier Support for Oracle 12.2.0.1

If you remember this, the Premier Support period for Oracle 12.2.0.1 ended on November 30, 2020.

Migrating Flashback Data Archive (FDA) tables

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 …

Why you can’t stay on Oracle Database 11g forever

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 Fail Safe is desupported in Oracle Database 21c

You may wonder about this message out of the blue. I wrote a blog post about Oracle Fail Safe being deprecated in Oracle 19c a while ago. But a customer recently pointed me to the fact that I didn’t blog about the fact that Oracle Fail Safe is desupported in Oracle Database 21c.

Deprecated? Desupported?

A very quick recap about what deprecated and desupported mean. In short, deprecated means “we don’t develop something further but it is still fully supported”. Whereas desupported means “it may still work or may be gone, and you …

AutoUpgrade 2.0 has been released – and got reuploaded

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 …
