Apply Patch 31088341 before Upgrade to prevent ORA-1403

As I learned from a customer this week, this patch is a must have when you use Partitioning and you attempt to upgrade to Oracle 19.9.0 or earlier. So please apply patch 31088341 before Upgrade to prevent ORA-1403 happening.

What is the issue?

This applies to all 19c upgrades at least until 19.9.0. You may see this error pattern in catupgrd0.log:

ORA-29702 – and your instance does not startup in the cluster anymore

This is the right blog post for a Friday 13th. And please forgive me – I wanted to put this on the blog earlier as two of my customers hit this weeks ago already. But it must have fallen through the cracks. Still, now it is hopefully not too late to tell you what you should do if you hit ORA-29702 – and your instance does not startup in the cluster anymore. Especially when you tested a database upgrade – and after a restore, the database doesn’t want to start, no matter what you try.

Upgrade Essentials – Videos for the Virtual Classroom Series 2020

Roy, Daniel and I ran 6 workshops in our Virtual Classroom Series 2000 format. Each of them is between 90 and 120 minutes. This sounds quite long but of course you can scroll forward if you are interested in only a part of it. We consider those the Upgrade Essentials – Videos for the Virtual Classroom Series 2020. As as we now completed the 6th web seminar, it’s time for a short recap.

Is Upgrade that complicated?

Good question. If upgrade is so easy as we say, why do you need 6 virtual sessions …

Solution for ORA-02303 from JSON_OBJECT_INVALID in upgrade to 19c

I just learned yesterday about this error – and as it seems to happen occasionally, you may want to read more about the Solution for ORA-02303 from JSON_OBJECT_INVALID in upgrade to 19c.

What happens?

You are upgrading a database to Oracle 19c, and you see this error pattern:

CREATE OR REPLACE TYPE JSON_Object_T AUTHID CURRENT_USER UNDER JSON_Element_T(
*
ERROR at line 1:
ORA-02303: cannot drop or replace a type with type or table dependents

This is coming when catjson.sql gets executed.

Why does it happen?

Unfortunately the FORCE option is missing when we create …

Receiving ORA-55940: An error occurred during execution of ktliIngestExternData

During my previous test with Unified Auditing Policies anomalies after upgrade to Oracle 19c, I also hit and error when I queried the unified audit trail. Hence, I make a reminder to myself and would like explain what to do in case you are Receiving ORA-55940: An error occurred during execution of ktliIngestExternData as well.

What a strange error

I created a few policies by myself and did a database upgrade from Oracle 12.2.0.1 to Oracle 19.8.0. And after upgrade, I wanted to check the records in my audit trail. But instead of …

Check your Unified Auditing Policies after upgrading to Oracle 19c

This may become a longer blog post. One of the customers I work with for many years contacted me a few weeks ago. After upgrade to 19c, it looked like as if some Unified Auditing Policies weren’t correct anymore. It started as a tiny issue, but thanks to the customer who analyzed down to the bones, it seems to be bigger than we thought at the beginning. So you may Check your Unified Auditing Policies after upgrading to Oracle 19c as well.

When Fixed Object Stats Gathering takes very long during upgrade …

Over the past days I exchanged several emails with a very important customer regarding Fixed Objects Stats gathering in relation to database upgrade. The customer found out that it takes very long in their environment – over an hour to be precise. Relaxing on the weekend helped me a bit. And this morning, it dawned me that I’ve had two similar cases before already. Plus I didn’t blog about it yet. Now it’s time to tell you a little but about Unified Auditing and the situation when Fixed Object Stats Gathering takes very long during upgrade …

ORA-1555 won’t get reported into alert.log anymore since 19.4.0

Many thanks to a German customer for showing me this tiny behavior change with Oracle Database RU 19.4.0. From this RU on the well known ORA-1555 won’t get reported into alert.log anymore since 19.4.0. But if you still like to see the “snapshot too old” error, then you can use a workaround.

Why has this been changed?

Actually this is something I don’t understand completely. It may be just a side effect. Unpublished fix bug 29424999 – DUMP MINIMAL DIAGNOSTICS BY DEFAULT IN CASE OF ORA-01555 IN ADW/ATP ENV has been

MGA Issue – and it is fixed with Oracle 19.8.0 and newer

Where do I start? One of the customer accounts I worked the longest time with recently upgraded to Oracle 19c on Exadata. They are an Exadata customer since 2009. After going live on 19c, a few days later they hit an MGA Issue – and it is fixed with Oracle 19.8.0 and newer. But question no.1 was: Why hasn’t Oracle warned us – and how could we have learned about it?

Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com

You may have realized that you will find mostly on-prem database upgrade and migration topics covered on my blog. Which doesn’t mean that you can’t use most of these techniques to migrate to the cloud either. But it’s really hard to write about everything in full detail. Hence, today I’d like to introduce you to Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com. And no, I was never a fan of this American boyband from the 80s and 90s 😉

AutoUpgrade with Transparent Data Encryption (TDE)

I knew, one fine day I will have to dig into TDE. Resistance is futile. There were so many questions regarding AutoUpgrade with Transparent Data Encryption (TDE) in the past weeks and months. And the team is still working hard on a solution to make the non-CDB to PDB plugin flawless and automated for such cases. But I won’t cover the latter in this post here. I will solely focus on the database upgrade itself.

Windows Only: Upgrade to Oracle 18.10.0 fails with ORA-01722

Liron Amitzi reported this on his blog a few days ago already. And it is a very nasty tiny little issue happening with RUs where the second number of the release enters the two-digit-space, such as 18.10.0. At this point, on Windows Only: Upgrade to Oracle 18.10.0 fails with ORA-01722. This happens late in the upgrade phase.

What is the issue?

The problem here is a tiny little piece in %ORACLE_HOME\admin\catupstr.sql – a SUBSTR function is used in a way that it does not take into account a potential two-digit …
