ORA-1422 and ORA-6512 from SYS.DBMS_STATS in Post Upgrade

Posted on May 4, 2021 by Mike.Dietrich Optimizer Patch Recommendation 2

Ernst Leber sent me an email today. He hit an error at a customer upgrading to Oracle 19.9.0 on Exadata with AutoUpgrade. ORA-1422 and ORA-6512 from SYS.DBMS_STATS in Post Upgrade were signaled – and he better flashed back to the Guaranteed Restore Point. He found even a MOS note but still had questions. So time to blog about it in case you hit this error sequence as well.

At first, this is not an AutoUpgrade issue. You may see the same error stack in the post upgrade …

Why do you need a password to download older patch bundles?

Posted on May 3, 2021 by Mike.Dietrich Patch Recommendation 4

A customer raised this question recently: Why do you need a password to download older patch bundles? The customer wanted to download a PSU from July 2020 on the MyOracle Support (MOS) platform but this wasn’t possible without a password.

Why is there an extra password required?

In MOS Note: 888.1 – Master Note for Database Proactive Patch Program we documented the following:

Through our review of customer Service Requests (SRs), we find that customers frequently run into issues because they have unknowingly downloaded

New parameters and features in Oracle Database 19.11.0

Posted on April 26, 2021 by Mike.Dietrich Behavior Change Patch Recommendation 4

As usual, as soon as I apply the newest RU, I do also a quick check for New parameters and defaults in Oracle Database 19.11.0.

New Parameters in Oracle 19.11.0

Based on customer feedback, there is one really big improvement since this RU release. Not only new features but also parameter changes get listed. You will find them in the 19c New Features Guide.

In this RU you will find only 1 new parameter:

The description says “Turn on/off dedicated optimization for DRCP” – and the default is “YES

Oracle 19c Installation with 19.11.0 RU, OJVM and some other fixes

Posted on April 22, 2021 by Mike.Dietrich Installation Oracle Database 19c Patch Recommendation 8

In an previous blog post we showed how to install and patch in one single action. And as I use this technique all the time when I setup new homes, would like to show you an Oracle 19c Installation with 19.11.0 RU, OJVM and some other fixes. The purpose of this blog post is mainly to demonstrate again how you can install and patch in one action. But also to help you avoiding a pitfall when you apply the OJVM RU from April 2021.

Patching all my environments with the April 2021 Patch Bundles

Posted on April 21, 2021 by Mike.Dietrich Patch Recommendation 12

Oh well, time flies. And it is April 2021, and hence I will start Patching all my environments with the April 2021 Patch Bundles. In my case, this will be 19.11.0 and 12.2.0.1 Release Updates. But there will be an additional blog post for the OJVM bundle, too.

As usual, an important annotation upfront: I patch in-place due to space issues. But in reality, you please patch always out-of-place with a separate home. Please see this blog post about how to apply the RU directly when you provision a new home with OUI…

Data Pump Super Patch for Oracle 19.10 and newer

Posted on April 15, 2021 by Mike.Dietrich Data Pump Patch Recommendation 33

Just a few days we released a Data Pump Super Patch for Oracle 19.10 and newer. “Newer” refers to the fact that once 19.11.0 will be available, this merge patch I’m writing about will be available as well right away (sorry, got delayed a bit). And if you work with Data Pump, you may want to consider this performance patch collection.

Where are AutoUpgrade error codes documented?

Posted on April 12, 2021 by Mike.Dietrich AutoUpgrade 0

I know, I didn’t blog for a while due to seminar preparations and holidays. But as I’m going through the open comments on the blog trying to answer them, I came across a question regarding the strange UPG error codes, AutoUpgrade is printing sometimes. And of course, where are AutoUpgrade error codes documented?

The UPG errors

Once AutoUpgrade hits an error condition, it prints an error code such as UPG-1400 or UPG-1303. And often, this error code is not very meaningful. In the comments section, somebody asked where to fine more information about these …

Workaround for sdoloadj.sql errors with Datapatch in 19.9.0 and 19.10.0

Posted on March 2, 2021 by Mike.Dietrich Flaws and Pitfalls 5

The other week a customer from my hometown alerted me about an issue they saw when applying the 19.9.0 RU. A long sequence of errors in the datapatch run, all of them signaled from sdoloadj.sql. They opened an SR. And Support had an – understandable – recommendation the customer didn’t want to implement: Install JAVAVM. But thanks to my PM mate, Hans Viehmann (Mr Spatial), here is a simple Workaround for sdoloadj.sql errors with Datapatch in 19.9.0 and 19.10.0. And it may even apply to later releases, too.

Posted on February 1, 2021 by Mike.Dietrich Optimizer Patch Recommendation 15

It’s been a while since I blogged about the DBMS_OPTIM_BUNDLE – and to me, the package is still sort of a mystery. Ideally you can least and enable or disable behavior changing optimizer fixes per RU. And in Oracle 19.10.0, you will find a new surprise. So You may need a one-off for DBMS_OPTIM_BUNDLE in 19.10.0.

Do you need the Mitigation Patch in CDB$ROOT and all PDBS?

Posted on January 25, 2021 by Mike.Dietrich JVM Patch Recommendation 10

Thanks to Axel Delin for asking this very reasonable question on the blog. Do you need the Mitigation Patch in CDB$ROOT and all PDBS? Background for this question is that Axel can’t remove JVM but doesn’t use it. A typical case we cover in our slides and presentations as well. And in this case, the Mitigation Patch will become your friend. Please note: If you DON’T have JAVAVM in your database, you won’t need to pay attention and instead could stop reading now.

Why is there a lib32 directory in Oracle 19.8.0 and 19.9.0?

Posted on December 21, 2020 by Mike.Dietrich Flaws and Pitfalls Installation Patch Recommendation 0

I received two emails from different customers within a week – and both asked the same thing: Why is there a lib32 directory in Oracle 19.8.0 and 19.9.0? In one case, it was more like “We are wondering” but in the other case it caused issues during patching.

Photo by Erik Mclean on Unsplash

What happens?

Due to a packaging issue most likely, there is a lib32 directory appearing after you patch your homes to either 19.8.0 or 19.9.0. With the next RU, 19.10.0, this should not be the case anymore.
