Patching all my environments with the July 2021 Patch Bundles

It’s patching day again. Hurray! Or not. I realize that at patching day, the 19c bundles are all missing. So wrote this blog post a bit after the usual release day. In my case this will include Oracle 19.12.0 RU and the July 2021 RU for Oracle 12.2.0.1. Please find the details about Patching all my environments with the July 2021 Patch Bundles below.

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

New version of AutoUpgrade (21.2) is available for download

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.

New version of AutoUpgrade (21.2) is available for download

The fact the tool has a 21c versioning does not affect 19c upgrades. There …

UNDO_RETENTION not inherited to PDBs anymore since 19.9.0

Behavior changes introduced via a bug fix may not be something you like a lot. And thanks to Sreedhar from one of our most important customers I learned on the weekend: UNDO_RETENTION not inherited to PDBs anymore since 19.9.0.

UNDO_RETENTION not inherited to PDBs anymore since 19.9.0

What is happening before 19.9.0?

Until Oracle 19.8.0 you could change the UNDO_RETENTION in the CDB$ROOT, and it applied to all PDBs automatically. You may or may not have cared. But there are cases when you’d like to change an undo related parameter in the CDB$ROOT without its propagation into all PDBs.

This behavior …

Bug Fixing Support for Oracle 18c ends June 30, 2021

Time flies so quickly. I remember when we had intense discussions with a very large automotive customer whether they should use Oracle 18c, or rather wait for Oracle 19c. They went straight to Oracle 19c. But I know that many customers out there are still on Oracle 18c. So this date coming up in less than 3 weeks is very important for you. Bug Fixing Support for Oracle 18c ends June 30, 2021.

Oracle Database 18c

I quickly checked on my blog. On March 20, 2018 I wrote When will Oracle Database 18c

Unplug / Plug / Upgrade with AutoUpgrade

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.

Test Setup

As test setup I use our Hands-On Lab.

I will …

Some very important MOS Notes when you upgrade and patch

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 …

Messaging Gateway – Upgrade can’t find mgwu122.sql

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.

Oracle Database Advanced Queuing provides propagation between two Oracle Database Advanced Queuing queues to enable e-business (HTTP through IDAP). Messaging Gateway extends

New parameters and features in Oracle Database 19.11.0

As usual, as soon as I apply the newest RU, I do also a quick check for New parameters and defaults in Oracle Database 19.11.0.

New Parameters in Oracle 19.11.0

Based on customer feedback, there is one really big improvement since this RU release. Not only new features but also parameter changes get listed. You will find them in the 19c New Features Guide.

In this RU you will find only 1 new parameter:

  • drcp_dedicated_opt
    The description says “Turn on/off dedicated optimization for DRCP” – and the default is “YES

As you already know, Oracle had introduced in the last few years a new database release model, and with the need to upgrade your database version more frequently to benefit from the latest features and innovations that Oracle brings to the market, a new challenge is presented!

Oracle Database 21c is now available but Oracle Database 19c remains the current “Long Term Support Release” and you can have it running both on-premises and in

Where are AutoUpgrade error codes documented?

I know, I didn’t blog for a while due to seminar preparations and holidays. But as I’m going through the open comments on the blog trying to answer them, I came across a question regarding the strange UPG error codes, AutoUpgrade is printing sometimes. And of course, where are AutoUpgrade error codes documented?

The UPG errors

Once AutoUpgrade hits an error condition, it prints an error code such as UPG-1400 or UPG-1303. And often, this error code is not very meaningful. In the comments section, somebody asked where to fine more information about these …

Oracle 19c on Windows may flood your trace file directory

Oh … it’s Windows week here. And all this even though since I didn’t install Oracle on Windows for quite a while. But of course I’m fully aware that many of you out there operate Oracle on Windows. In this particular case thanks to Joël for the pointer to this issue. Oracle 19c on Windows may flood your trace file directory.

What happens?

In every release of Oracle 19c, at least until 19.10.0 BP, you may find out that every few minutes a trace file gets written into the %ORACLE_BASE%\diag\..\..\trace directory. And all …

ORA-12638 on Windows only from Oracle 19.10.0 onwards

You like unexpected changes and surprises, don’t you? And especially those which aren’t in the patch notes or the docs. I blogged about such changes a few weeks ago. And thanks to the people reading this blog, I learned now about another change with Oracle 19.10.0 on the Windows platform. You may receive now an ORA-12638 on Windows only from Oracle 19.10.0 onwards.

What has been changed?

So at first, thanks to Ernst and Marcus for bringing this to my attention. This is an issue which happens on MS Windows only.

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.

Apply Patch 31088341 before Upgrade to prevent ORA-1403

As I learned from a customer this week, this patch is a must have when you use Partitioning and you attempt to upgrade to Oracle 19.9.0 or earlier. So please apply patch 31088341 before Upgrade to prevent ORA-1403 happening.

What is the issue?

This applies to all 19c upgrades at least until 19.9.0.

The fix is included from 19.10.0 Release Update onward. So if you are upgrading to 19.10.0 or higher, you can stop reading here (thanks Pablo for the hint!).

Fixed Objects Stats Gathering Fails – what do you do now?

A few days ago I blogged about what you could do when Fixed Objects Stats Gathering is slow in an upgrade process. You can skip the preupgrade gathering, and the postupgrade gathering does not happen anymore since the October 2020 version of AutoUpgrade. Still, I came across another issue the other day: Fixed Objects Stats Gathering Fails – what do you do now?

What happened?

Actually this is connected to the Fixed Objects Stats Gathering is slow in an upgrade case. The customer encountered an incredible long runtime. And the support engineer …
