Why is the fix for bug nnn not included in any RU?

Posted on September 8, 2026 by Optimizer Patch Recommendation 0

Christian asked this question today. Specifically, in his case for Bug 26749785 – PERF_DIAG: NEED TO HAVE MORE CONTROL IN DICTIONARY FOR AUTO_STATS_ADVISOR_TASK. Several of his customers suffer from this issue, and they repeatedly need to ask for backports or merge patches. I have seen this several times as well. Anyway, he is not only one who asked: Why is the fix for bug nnn not included in any RU?

Long-Term Release Updates are paused

Posted on July 17, 2026 by Oracle Database 19c Patch Recommendation Release Schedule 2

Since several customers asked me about it, I realized that I have never blogged about LTRUs – and as of now, Long-Term Release Updates are paused. Let me explain what the concept meant, where you can find information about it and what it would mean in your environment.

Long-Term Release Update

The idea is smart for those customers who can’t move forward on Release Updates (RU) as quickly as we recommend it. Which means: apply them quarterly. Long-Term Release Updates (LTRU) seemed to be a good approach. You take an LTRU, and then we …

Posted on February 9, 2026 by Flaws and Pitfalls Oracle Database 19c Patch Recommendation 44

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?

Posted on February 5, 2026 by ORAdiff Patch Recommendation 6

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!).

Ask ORAdiff …

I am using this specific customer case as an example. Of course, this will work with your list of fixes as well. Let’s assume that this is the list of one-off …
