Patch Recommendation

Important Recommended Patches for Oracle Database 19c

It took a while – but now you can find a new MyOracle Support (MOS) Note with a list of Important Recommended Patches for Oracle Database 19c. It is actually a must-read, regardless whether you are upgrading or migration to 19c, or in case you are already on 19c.

What do you get?

Please check MOS Note: 2720807.1 – Oracle Database 19c Important Recommended One-off Patches. It gives you a list of important fixes for Oracle Database 19c. In the initial version of the note you could select for each available Release …

Oracle Database 19.10.0 and Blockchain Tables and COMPATIBLE

Many of you recognized that we delivered a new feature with Oracle Database 19.10.0, the January 2021 Release Upgrade. So I’d like to put a few interesting things together from the upgrade and migration perspective regarding Oracle Database 19.10.0 and Blockchain Tables and COMPATIBLE.

What are Blockchain Tables?

At first, I don’t want to repeat what other people have blogged and written about already. You may just go through the blog posts of Connor McDonald and Tim Hall and others to learn more about this cool feature.

You may need a one-off for DBMS_OPTIM_BUNDLE in 19.10.0

It’s been a while since I blogged about the DBMS_OPTIM_BUNDLE – and to me, the package is still sort of a mystery. Ideally you can least and enable or disable behavior changing optimizer fixes per RU. And in Oracle 19.10.0, you will find a new surprise. So You may need a one-off for DBMS_OPTIM_BUNDLE in 19.10.0.

No RURs for 12.2.0.1 – and Oracle 11.2.0.4 left Extended Support

Last week I blogged about the quarterly patching fun when applying the Release Updates to my environments. But I completely forget to mention and explain a few things. There are No RURs for 12.2.0.1 – and Oracle 11.2.0.4 left Extended Support.

No Release Update Revisions for Oracle 12.2.0.1

Thanks to my friend Rodrigo Jorge who messaged me on the weekend. He goes way deeper with applying the quarterly patches and highlights the differences. And he recognized and blogged already about the fact that there are no RURs available for Oracle 12.2.0.1.

And …

Do you need the Mitigation Patch in CDB$ROOT and all PDBS?

Thanks to Axel Delin for asking this very reasonable question on the blog. Do you need the Mitigation Patch in CDB$ROOT and all PDBS? Background for this question is that Axel can’t remove JVM but doesn’t use it. A typical case we cover in our slides and presentations as well. And in this case, the Mitigation Patch will become your friend. Please note: If you DON’T have JAVAVM in your database, you won’t need to pay attention and instead could stop reading now.

Patching all my environments with the January 2021 OJVM Bundles

You may have read my blog post from the other day about patching my environments with the January 2021 Release Updates. But as I installed now Java in all my databases for testing purposes, I will quickly demonstrate how Patching all my environments with the January 2021 OJVM Bundles works.

Security Alert January 2021

Let me start with the Security Alert for January 2021. And don’t forget to take a look at the Oracle Database Server Risk Matrix for January 2021. This time, the is a 4.8 risk score issue with …

Patching all my environments with the January 2021 Patch Bundles

Groundhog day on the upgrade blog. It’s time for my quaterly Patching all my environments with the January 2021 Patch Bundles blog post. And still no RAC and ASM. Sorry for that … too many virtual events and other tasks since months unfortunately.

As usual, an important annotation upfront: I patch in-place due to space issues. But in reality, you please patch always out-of-place with a separate home. Please see this blog post about how to apply the RU directly when you provision a new home with OUI.

Why is there a lib32 directory in Oracle 19.8.0 and 19.9.0?

I received two emails from different customers within a week – and both asked the same thing: Why is there a lib32 directory in Oracle 19.8.0 and 19.9.0? In one case, it was more like “We are wondering” but in the other case it caused issues during patching.

Why is there a lib32 directory in Oracle 19.8.0 and 19.9.0?

What happens?

Due to a packaging issue most likely, there is a lib32 directory appearing after you patch your homes to either 19.8.0 or 19.9.0. With the next RU, 19.10.0, this should not be the case anymore.

Why does this sound strage?

The first customer who …

ORA-29702 – and your instance does not startup in the cluster anymore

This is the right blog post for a Friday 13th. And please forgive me – I wanted to put this on the blog earlier as two of my customers hit this weeks ago already. But it must have fallen through the cracks. Still, now it is hopefully not too late to tell you what you should do if you hit ORA-29702 – and your instance does not startup in the cluster anymore. Especially when you tested a database upgrade – and after a restore, the database doesn’t want to start, no matter what you try.

Why is the 19.9.0 Release Update not available yet for MY platform?

I’ve had a week off and tried to relax and stay away from work topics (which worked quite well this time). The downside is 300+ emails in the inbox. And I spotted several ones already asking: Why is the 19.9.0 Release Update not available yet for MY platform?

Details for Patch 123456789 not found.

At first, this is not a uncommon question. And the root cause is two-fold. As you know from my quarterly blog posts such as Patching all my environments with the October 2020 Patch Bundles, these notes are important:

Patching all my environments with the October 2020 Patch Bundles

I have to confess: Time didn’t allow to rearrange my lab yet to have GI and ASM. Hence, this will be another blog post about Patching all my environments with the October 2020 Patch Bundles with only non-RAC patching. But it is in the works …

As usual, an important annotation upfront: I patch in-place due to space issues. But in reality, you please patch always out-of-place with a separate home. Please see this blog post about how to apply the RU directly when you provision a new home with OUI.

Upgrade fails with ORA-20001 during datapatch run

I encountered this issue now multiple times in my own environment. And I searched MOS and tried different things. But I couldn’t solve it yet. My Upgrade fails with ORA-20001 during datapatch run – and I’d like to show you how to bring the upgrade to an successful end.

It all starts with an upgrade

In my lab environment I upgrade two databases often in parallel. An 11.2.0.4 database and a 12.2.0.1. The 11.2.0.4 upgrades always flawless. But the 12.2.0.1 occasionally fails. This is the screen AutoUpgrade is showing me – but this is not …

Install and Patch in one single action with OUI

This is such a common case: You want to install a new Oracle Home and you’d like to apply the most recent patch bundle to it as well. But as we don’t officially offer Gold Images to download where the RU is included already, you have to do three tasks instead of one. But you can avoid this and Install and Patch in one single action with OUI.

Recommendation and 3 standard actions

We always recommend that you apply the most recent RU. Hence, usually you will download Oracle Database 19.3.0 from …

datapatch and OPatch documentation and MOS note

Did you ever ask yourself whether there is documentation available for OPatch and for datapatch? It is not easy to find. And you won’t find it under “Database” in the Oracle Bookshelf. So today I would like to guide you in this short blog post to the datapatch and OPatch documentation and MOS note.

OPatch? Datapatch?

Just to recap: You use OPatch (or opatchauto) to apply the binaries to an Oracle installation. As a result, you change the second or the third number of the release from Oracle 19.5.0 to Oracle 19.8.0. But …

Patching all my environments with the July 2020 Patch Bundles

Quarterly routine: When the new security alert get published, then it is patching time again. I’ll show you as usual how Patching all my environments with the July 2020 Patch Bundles works. And I heard your comments – in the next round in October, I will do this for GI and OJVM most likely, too. If not earlier …

And just an important annotation upfront: I patch in-place due to space issues. But in reality, you please patch always out-of-place with a separate home.

DBMS_JOB one-off patch needed for Oracle 19.3.0 – 19.7.0

A while ago I blogged already about this behavior change for DBMS_JOB in Oracle Database 19c. Many of you are aware of this. But today I learned something new about it. Kudos to Alexey Makhmutov for bringing this to my attention. There is a very important fix you will need on top in 19c to avoid performance issues. If you rely on jobs with the old job interface, take note: DBMS_JOB one-off patch needed for Oracle 19.3.0 – 19.7.0

JDK patching happens with every RU since January 2020

A while ago, a customer asked me whether he needs to apply JDK patches separately. He discovered that the JDK in the $ORACLE_HOME is quite outdated. But there was no clear answer available. And the MOS Note he pointed me to, seemed to be quite incomplete. But times have changed. And JDK patching happens with every RU since January 2020.

OPatch Alert: Be aware of cleanup issues – and the JDK version

This is just a quick alert blog post for Friday with an OPatch Alert: Be aware of cleanup issues – and the JDK version. And thanks to several people who either commented or mailed me directly and asked if I could alert others as well.

OPatch cleanup issue

At first, you may have read earlier this week my article about patching my environments with the April 2020 bundle patches. For my patch activity, I’ve had to exchange my OPatch versions for 11.2.0.4, 12.2.0.1 and 19.7.0. And I guess, I would have had …

Let’s start with the Security Alerts for April 2020. It leads me to the April 2020 Critical Patch Advisory.

Do you need to apply OJVM patches to Grid Infrastructure?

From time to time, when I discuss OJVM patching with customers, I hear the following question: Do you need to apply OJVM patches to Grid Infrastructure? I’m carrying around this topic since months actually.

A quick MOS check

Well, you’d assume this is something MOS does give you an answer within fractions of a second. But nope. I found a lot but unfortunately not what I was looking for. What I found instead where community discussions where applying OJVM patches to a 12.1.0.2 GI installation corrupted the inventory. Hence, there seems to be some …

Do you need STARTUP UPGRADE for OJVM?

Actually I carry around this topic with me since the October 2019 workshop in Dubai. We’ve had one of these OJVM Patching discussions I’d like to escape usually. Anyhow, during this session, it dawned me that the STARTUP UPGRADE requirement in the OJVM readme may be not correct anymore. So the question will be: Do you need STARTUP UPGRADE for OJVM?

Patching all my environments with the January 2020 Patch Bundles

I was traveling last week and had not enough time to download and apply the January 2020 Release Updates and PSUs. Yes, I’m one week late. But nevertheless, I’d like to check whether patching my databases with the January 2020 RUs will work fine.

Save Patching Downtime with Oracle Multitenant?

At OOW 2019 we announced that you can have up to 3 user-created pluggable databases (PDBs) per container database (CDB) without having a Multitenant license. And in this blog post I’d like to demonstrate how you can save patching downtime with Oracle Multitenant.

The Concept

The idea this entire process settles on is very simple. When you create a fresh container database in the target (already patched!) environment, you don’t have to patch this one. You only have to relocate the PDB from the source into the target CDB. In addition, only datapatch needs to be executed. As the …

Patching all my environments with the Oct 2019 Patch Bundles

Yesterday I blogged about the Oct 2019 Patch Bundles being available for download. And while I wrote this blog post, I downloaded all of them for my environments. Here I’d like to share with you the most simple path to apply them. As I have no cluster or ASM, I don’t have to patch Grid Infrastructure. And I don’t even have OJVM in any of my databases right now. Due to space constraints in my lab environment I will apply the patches in-place. You shouldn’t do this but instead use always a new home you patch. This allows you …

Critical Patch Alert October 2019

At first, I check the Alert and the Risk Matrix whether critical issues with a high risk score are included. I will install the patch bundles anyway, but I’m curious. In my particular case I will take care on the database only. You of course will check for other products you are using, too.
