Migrating Flashback Data Archive (FDA) tables

This morning I received an email question from a customer asking whether there is support for the Migrating Flashback Data Archive (FDA) tables in Oracle 19c. And since this is not the first time I received this question, I thought it may be good to have a blog post about it.

What is Flashback Data Archive (FDA)?

Well, google it. Actually I was looking for a link in our documentation but to my surprise I found the usual suspects such as Tim Hall’s excellent oracle-base page – but not much in our own doc …

Virtual Classroom Seminar 12: Migrating Very Large Databases on Dec 9, 2021

It looks to me that every possible event in 2021 happens in October/November/December 2021. No complaint from my side – but just in case you wonder about so little update activity on our blogs since weeks. We are just so busy in delivering virtual seminars. Which is good – but it requires lots of effort on our side as we want to deliver decent quality and real tech content. And now, since the year is almost at its end, it is time for our final Virtual Classroom Seminar 12: Migrating Very Large Databases on Dec 9, 2021 this year.

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.

Check your Unified Auditing Policies after upgrading to Oracle 19c

This may become a longer blog post. One of the customers I work with for many years contacted me a few weeks ago. After upgrade to 19c, it looked like as if some Unified Auditing Policies weren’t correct anymore. It started as a tiny issue, but thanks to the customer who analyzed down to the bones, it seems to be bigger than we thought at the beginning. So you may Check your Unified Auditing Policies after upgrading to Oracle 19c as well.

Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com

You may have realized that you will find mostly on-prem database upgrade and migration topics covered on my blog. Which doesn’t mean that you can’t use most of these techniques to migrate to the cloud either. But it’s really hard to write about everything in full detail. Hence, today I’d like to introduce you to Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com. And no, I was never a fan of this American boyband from the 80s and 90s 😉

Thank you, Barcelona – I’ll be back soon :)

I stopped more or less watching Champions League football since it is available on pay TV only for over a year in Germany. But of course I saw the result yesterday: Barca lifting Dortmund into the play-off stage by beating Inter in Milano. Well, I guess, all BVB fans will have celebrated yesterday night. Still, the reason for my blog post is not football. But I’d like to say Thank you, Barcelona – I’ll be back soon 🙂

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

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.
