How to deal with statistics when you migrate? Have you done migration projects in the past, or do you have some upcoming projects, and you wonder how you should treat all sorts of statistics in your database? What is the better option? Keep and migrate the existing ones? Regather them right away?…

CPU, CSPU, MRP, RU – some clarifications I just returned from a 2 week vacation in Asia this weekend. And I was following from a distance. On May 28, the first CSPUs got released, some MOS notes got published. There are a lot of patching options now. CPU, CSPU, MRP, RU - some clarifications may be…

Does OJVM patching fail again with ORA-1403 in 19.31? Some of you had been trapped by ORA-1403 during patching to Oracle Database 19.30. I blogged about this in February this year, and I had to update the blog post a few times until we collected all the issues. The root cause got fixed and…

OCW 19.28 contains a tiny behavior change with DB_UNIQUE_NAME A colleague brought this to my attention the other week. And since the blog serves also as my partial memory, I wanted to put this out quickly. It is not a big deal, and most of you will never see this or be affected by it. Still, some…

Does AutoUpgrade support the MOVE option? Sometimes you have different plans for the day. Or, in my case, the day just needs a few extra hours. Today, I received a very interesting question on the blog at first by a customer I know very well. Then we exchanged mails - and I was caught by…

Sign up for the next Virtual Classroom Seminar: Patch Smarter, Not Harder Some of you may have realized: We moved the Virtual Classroom Seminar #27 from its original date in February to March 12 this week. Usually we don't do this - but we ended up with so much content. If you haven't already, it…

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…

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…

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…
