Refreshable Clone PDB – From 19.27(DST 44) to 26ai (DST 43) using AutoUpgrade

alexzaballa.com/oracle-pdb-r...

Upgrade Oracle Database 19c PDB to 26ai Here's how to upgrade a single PDB. It's a faster approach, but consider your rollback options.

Upgrading a single PDB is a faster and more flexible option compared to a full CDB upgrade. But take about on your rollback plan.

Don’t use AI to build your AutoUpgrade config file, please! Let me do a quick Friday rant. Many of you can easily ignore this. But regardless of whether you are a colleague, a friend, a customer, a partner or just exploring AutoUpgrade because it is the coolest small tiny little tool Oracle has to offer, don't use AI to build your AutoUpgrade config file, please! AI models are great ...

OJVM patching fails with ORA-1403 in 19.30 if JAVAVM is not installed Thanks to all the people (Jeff, Daniele, Lothar and others) who alerted me about this topic. Some of you had even created their own fix already. So, this is about an issue which happens only if you have no JAVAVM installed in your database or PDB but you still apply the OJVM Bundle on to of the Oracle Database 19.30 Release Update.

The February 2026 release of AutoUpgrade (26.2) is available This is a ground-breaking new release of AutoUpgrade, and the team worked hard to release it last weekend. This means for you that you should renew your AutoUpgrade tools as The February 2026 release of AutoUpgrade (26.2) is available now for download. 1..2..3..4..5..0 ... In case you wonder about this cryptic headline, no worries. Stefan Panek from TK smiled at me yesterday and said: "You've picked one of the best possible MOS note numbers in the new portal!".

What has happened to the 19.29 and 19.30 RUs? Many of you mailed us asking why AutoUpgrade does not download 19.29 or 19.30 RUs anymore. Others just noticed that the RUs got pulled without further communication visible. And a few people informed me about an issue with the 19.30 RU when you don't have OJVM configured but install the OJVM bundle. So, what has happened to the 19.29 and 19.30 RUs??

How do you check whether a list of bug fixes is included in an RU? Today, a customer sent me a workaround for the misbehavior they were seeing with the Conflict Checker Tool in the Support portal. They use oradiff to check whether a given fix they have a one-off right now is included in a future Release Update (RU). This works nicely, but I have a recommendation for an even easier check (thanks Rodrigo!).
