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.

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!".

Ok, then you should not see this. You have the newest opatch installed as well? If it still takes this long, then open an SR please and Support checking it

Oh wait - now I am puzzled. Are you patching into an existing home or are you doing a fresh install with the most recent patch bundle?

Then this is expected - the xml file tracking the fixes gets bigger and bigger with every run, and thus the opatch check takes longer. Check my blog for "opatch util deleteinactivepatches" please.

Do you patch in-place into the existing home, or out-of-place into a brand new home? If the latter is the way you go, do you do a fresh install or clone an existing home?

Thanks

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!).

A kill-switch terminates blocking sessions during patching You will find a good number of datapatch posts on my blog. And with Oracle AI Database 26ai from RU 23.26.0.0.0 onward (the October 2025 RU), we introduce a new functionality when you run datapatch: A kill-switch terminates blocking sessions during patching. What is changing? From Oracle AI Database 26ai onwards by default the invocation of datapatch will terminate any session currently holding a requested KGL X lock (Kernel Global Lock), an exclusive lock on an SQL or an PL/SQL procedure.

ORA-43907: Potential behavior change with Oracle RU 19.28.0 As I said multiple times, we have the best and most knowledgeable customers out there. Julian Frey is one of them, and there is a good and legit reason why he is an ACE Director since (I think) two years. Julian alerted me the other day about an ORA-43907: Potential behavior change with Oracle RU 19.28.0. And I guess, some of you would like to learn about this, too.

AutoUpgrade patching – getting started with Connor McDonald AIOUG OC Yatra 2025 is over, and I somehow recovered as well. As I wrote here, it was (again) an incredible experience with all those wonderful people (you!!) and those crazy speakers (us!) - and I learned a lot again. Still, I had no clue that Database and Developer evangelist and video wizard Connor McDonald would react to my friendly nagging 🙂

AHUBFILE files in ASM in Oracle 23ai – what is it? I really love our customers. Many people are so super-smart. A few weeks ago I delivered a full-day hands-on workshop for ora2know in Munich and some (positively) crazy people fly in very early morning from the other end of Germany to attend. Others catch a train at night time (which is the bigger adventure in Germany these days). I feel really grateful since this was also a pay-for-it workshop.
