upgrade

Which releases allow you to upgrade to Oracle Database 21c?

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?

Upgrade-supported Releases

The Database Upgrade Guide for Oracle 21c is your best friend here. Right at the beginning in the first chapter you will find this …

Pitfall: Upgrade to 21c fails when ORDIM is present but no SDO

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.

Upgrading a non-CDB to Oracle Database 21c with AutoUpgrade

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.

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

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:

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 …

Upgrade to Oracle 19c on Exadata with AutoUpgrade

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 …

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

ORA-1422 and ORA-6512 from SYS.DBMS_STATS in Post Upgrade

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 …

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 …

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!).
