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

AutoUpgrade with Transparent Data Encryption (TDE)

Posted on July 30, 2020 by Mike.Dietrich AutoUpgrade TDE - Transparent Database Encryption 28

I knew, one fine day I will have to dig into TDE. Resistance is futile. There were so many questions regarding AutoUpgrade with Transparent Data Encryption (TDE) in the past weeks and months. And the team is still working hard on a solution to make the non-CDB to PDB plugin flawless and automated for such cases. But I won’t cover the latter in this post here. I will solely focus on the database upgrade itself.

AutoUpgrade and Plug In to a CDB – with a single command (and video)

Posted on May 20, 2020 by Mike.Dietrich AutoUpgrade Single-/Multitenant 71

I have to confess, this feature is out and available for quite a while. But only unofficially. AutoUpgrade can upgrade and plug in a non-CDB into a CDB. But it lacked flexibility. And we didn’t test it a lot. Hence, you could find it documented in our Hands-On Lab instructions. And we did this exercise with you already in our sold-out labs at OOW 2019 as well. But since a week and a bit, it is officially supported: AutoUpgrade and Plug In to a CDB – with a single command (and video).

What has been announced?

Today at OOW 2019, Jenny Tsai-Smith and Dominic Giles announced in their talk that the non-CDB architecture will be desupported from Oracle 21c on. But VERY IMPORTANT, from Oracle 19c on you can have 3 user-created pluggable databases of any type without a Multitenant license. As soon as you have need for 4 or more PDBs within one container database, you will need a Multitenant license.

Database Migration from non-CDB to PDB – Migration with Data Pump

Posted on August 14, 2019 by Mike.Dietrich Data Pump Single-/Multitenant 14

You may have realized that there are a few techniques missing describing how to do a Database Migration from non-CDB to PDB – Migration with Data Pump is one of them. I will explain the most simple approach of going to Single- or Multitenant. It isn’t the coolest – and it isn’t very fast as soon as your database has a significant size. But it is not complex. And it allows you to move even from very old versions directly into an Oracle 19c PDB – regardless of patch levels or source and destination platform.

Database Migration from non-CDB to PDB – Typical Plugin Issues and Workarounds

Database Migration from non-CDB to PDB – Clone via NON$CDB, upgrade, convert

Posted on July 25, 2019 by Mike.Dietrich Single-/Multitenant 13

The third option for plugging in a non-CDB is called Database Migration from non-CDB to PDB – Clone via NON$CDB, upgrade, convert. As I showed already in this blog post a while ago, your source must be at least an Oracle 12.1 database. And this technique can be used also only for same-Endianness migrations but does not apply if you’d like to migrate from Big to Little Endian. If your source database matches already the receiving CDB, no upgrade is necessary.

Database Migration from non-CDB to PDB – Overview

Posted on July 22, 2019 by Mike.Dietrich Single-/Multitenant 5

Database Migration from non-CDB to PDB – Overview

When you plan to move from non-CDB, the Oracle term for regular database deployments, to a Pluggable Database (PDB), you will migrate your database. It will become a PDB and run as part of a Container Database (CDB). This is a well known concept for several years now called Oracle Multitenant. If you …

Sometimes it is necessary to warn you about known pitfalls to avoid frustration. In this particular case I decided not to blog about it simply because I thought this won’t happen to too many other people. Well, yesterday my good friend Philippe Fierens dropped me a message about an issue he ran into with a Transportable Tablespace PDB Migration and Local Undo. And I immediately knew what caused him trouble – and I regret that I didn’t blog about it (sorry Philippe!). We’ve seen the same problem with a large ExaCC migration project …

Unified Auditing policies can slow down the upgrade

Posted on August 28, 2018 by Mike.Dietrich Auditing 0

I posted several blog posts about Unified Auditing in the past. And recently a large customer in the UK alerted me about their upgrades with PDBs from 12.1 to 12.2 taking much longer when Unified Auditing policies were enabled. It looks like as if Unified Auditing policies can slow down the upgrade.

We did some further investigations. See the results below.

You find a good number of blog posts explaining how to migrate to Unified Auditing, the performance tweaks in Oracle 12.1.0.2 and some other things:

Cloning with Pluggable Databases in Oracle 18c

We had several discussions on the internal mailing lists the other day about cloning with Pluggable Databases in Oracle 18c (or 12.2.0.1). And I blogged about this topic a while ago but realized I may need to refresh this a bit.

My example from the old blog post still works fine. But I realized that I switched my database into read-only mode. Hence, I like to repeat it and check different options.

Oracle Label Security (OLS) clean up in Oracle Database 11.2-19c is almost as simple and straight forward as removing OWM or APEX. You can do it online without downtime.
