Continue reading...Thanks a lot to all of you who participated also in our second seminar. Below you find now 3 Live Seminars: Upgrade and Performance Seminar 2 Questions answered.
I this blog post I answer all questions from the second seminar about AutoUpgrade to Oracle 19c and Performance Stability. Please find the links to the other QAs for Seminar 1 (Release Strategy, Patching and Cool Features) and Seminar 3 (Migration to Multitenant) below in the Links section of this blog post.

Please apologize that it took me a bit longer to upload a new version of our comprehensive slide deck. You can download now a new version of “Upgrade / Migrate / Consolidate to Oracle 19c” via the blog’s download page.
Since Oracle Open World 2019 we have a new corporate template. And while I like the graphics quite a bit, I’d say, the people who built it have a good sense for graphics. But they aren’t powerpoint experts. In fact, almost every slide had to be adjusted. This may not be a huge …
Continue reading...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.

There are several pitfalls when you plugin a non-CDB into a CDB environment. I’d like to highlight some of them – and show you potential workarounds as well. This is part of a series of blog posts to make your migration from non-CDB to PDB a bit smoother.
When we start to look at a migration from non-CDB to PDB for an important system, regardless of migrating on-prem or to the cloud, reducing the downtime is very important. In this blog post I’d like to highlight the different aspects …

As I work with customers on upgrades and migrations for a very long time, I know how important a proper fallback is.

In all the previous blog posts of this series I tried to explain specific pitfalls, and how you can workaround them. This article is meant to collect the “leftovers”, the minor issues and pitfalls which you may not …

When you consolidate on a larger scale, it is very likely that you have different patch levels in your database environments. But when you attempt to plugin a non-CDB into a CDB, you may see …

With component we mean the database component which you can find in DBA_REGISTRY – or CDB_REGISTRY. When Multitenant became available over 5 years ago, a decision had been made to make all options/components mandatory in a container database. This decision had to …

Interestingly, there is no issue with different time zone settings within a single CDB. Your CDB$ROOT can be on DST V.32 whereas a PDB you plugin can be already on DST V.33. But only …

When you migrate your non-CDB to PDB, in most cases the COMPATIBLE setting of the non-CDB will be lower than the setting of the receiving CDB. But still in this case you may see warnings. I will explain how to deal with …
Continue reading...In the previous blog posts I showed different approaches on how to migrate your database on a same Endianness platform into Multitenant. Whether you prefer to upgrade first or plugin first is up to you. I recommend upgrading first as this allows you a seamless fallback. But regardless of which approach you prefer, you may take care on potential pitfalls. Hence, this blog post is about Database Migration from non-CDB to PDB – Typical Plugin Issues and Workarounds. It may not be complete when I publish it and I may extend it later on. Let me know if you have …
Continue reading...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.
