Oracle Database 19c on Oracle Linux 9 (OL9): Installation Articles and Vagrant Builds

Earlier this year I wrote a rant about the lack of product certifications on Oracle Linux 9 (OL9).

One of the points I made was we are having to replace OL7 servers, but were forced to go to OL8 because Oracle 19c was not certified on OL9, and Oracle 23c on-prem is not available.

This blog post by Mike DieTrich changed all that because now 19c is certified on OL9, provided you are on patch 19.19 or above, and are on the correct version of UEK or the RHEL kernel. See Mike’s post for details.

Installation Articles

Of course, this triggered some installation articles.

Vagrant Builds

There are database, RAC and Data Guard vagrant builds here.

Odd Occurrence

I noticed something a little odd when doing these builds using the 19.21 RU patches.

For the database and Data Guard builds I used the DB RU and OJVM combo patch, and I was still forced to fake the distribution using the CV_ASSUME_DISTID environment variable. For the RAC build I used the GI RU and OJVM combo patch, and I didn’t need to fake the distribution.

I went back to the DB build, and instead used the GI RU and OJVM combo patch, and I no longer needed to fake the distribution. So it looks like there is something different about the database patches between these two types of RUs that slightly affect the installation process. It’s no big deal, but it might catch you out.

Oracle 19c is old. Why do you care?

We are in the process of replacing a load of VMs that are currently running OL7, and we want to go to OL9. Prior to this announcement were were going to have to do one of two things.

  • Migrate to 19c on OL8, which would be OK for 23c when it drops, but not ideal as building an OL8 box now seems like a fail.
  • Wait for 23c on-prem to drop and move to 23c on OL9. The problem here is we could run out of time waiting for 23c to come.

This announcement gives us a new option.

  • Migrate to 19c on OL9, then upgrade to 23c when the on-prem version drops.

This third option is way better for us!

Remember

There are a couple of things to remember.

  • You need to be on 19c to upgrade to 23c, so getting your 19c database on an OS that is supported for 23c is important. We’ve had confirmation that 23c will be available for OL8 and OL9 on release.
  • The extended support waiver for 19c was increased from 1 year to 2 years. Mike also wrote about this here. That means you get free extended support for 19c until April 30, 2026.

Conclusion

This is massive for us. I’m very happy!

Fedora 36 and Oracle

Fedora 36 was released recently. Here comes the standard warning.

Here are the usual things I do when a new version of Fedora comes out.

Why do I do this? As mentioned in the first link, Fedora is a proving ground for future versions of RHEL, and therefore Oracle Linux. I like to see what is coming around the corner. Doing this has no “real world” value, but I’m a geek, and this is what geeks do. 🙂

As an aside, when Fedora 35 was released I was having a lot of trouble getting 19c and 21c installed on it. I tried a number of times over the course of a few weeks and failed each time. When I tried those same installations on Fedora 36 they just worked, so I went back and tried on Fedora 35 again, and they worked there too. Clearly there have been some changes to underlying Fedora 35 packages that have fixed whatever the problem was with the Oracle installations. As a result, I also produced these.

Now that Fedora 36 exists, these Fedora 35 installations are not really necessary, but it’s nice to do them for the sake of completeness.

I pushed Vagrant builds to my GitHub.

If you want to try these out, you will need to build the base Vagrant boxes using Packer. You can find the Packer builds on my GitHub too.

So now you know how to do it, please don’t! 🙂

What’s New?

So what’s new with Fedora 36? It’s a bleeding edge distribution, so as you might expect, loads of package version updates, bringing most things to the latest and greatest versions. The things that stand out for me are Ansible 5 and Podman 4.0. If you want a more complete perspective on this, you might want to look here.

Video : DBMS_XPLAN : Compare Execution Plans in Oracle Database 19c and 21c

In today’s video we’ll demonstrate the compare plans routines, added to the DBMS_XPLAN package in Oracle database 19c and 21c.

The video is based on the following article.

Video : Immutable Tables in Oracle Database 19c and 21c

In today’s video we demonstrate immutable tables, introduced in the April quarterly patches for Oracle database 19c and 21c

The video is based on this article.

You’ll notice a striking resemblance to the syntax of blockchain tables, because they are essentially blockchain tables without the rows chained using cryptographic hashes. You can check out blockchain tables here.

Video : Vagrant Oracle Real Application Clusters (RAC) Build

In today’s video we’ll discuss how to build a 2-node RAC setup using Vagrant.

This video is based on the OL8 19c RAC build, but it’s similar to that of the OL7 19c RAC build also. If you don’t have access to the patches from MOS, stick with the OL7 build, as it will work with the 19.3 base release. The GitHub repos are listed here.

If you need some more words to read, you can find descriptions of the builds here, as well as a beginners guide to Vagrant.

The video is a talk through of using the build, not an explanation of each individual step in the build, as that would be a really long video. If you just want a RAC to play with, run the build and you’ll have one. If you want to learn about the steps involved in doing a RAC build, read the scripts that make up the build. Please don’t ask for a GUI step through of a build or I’ll be forced to ask you to read Why no GUI installations anymore? 🙂

Video : Real-Time Statistics in Oracle Database 19c

In today’s video we’ll give a demonstration of Real-Time Statistics in Oracle Database 19c.

This video is based on the following article.

This is essentially a follow-on from the previous video and article.

The star of today’s video is Ludovico Caldara, who is rocking a rather “different” look. I’ll leave it to you to decide if it’s an improvement or not! 🙂

Video : Resource Manager : SQL Quarantine in Oracle Database 19c Onward

In today’s video we give a quick demonstration of using the SQL Quarantine features of Oracle Database 19c.

It’s a follow-on to last week’s video.

Today’s video is a cut down of this article.

These might come in handy too.

The star of today’s video is Martin Widlake. I put out a message to “The Family” as I had run out of “.com” clips, and Martin was the first one back. He sent three, but this one had me laughing, and suited the quarantine theme. 🙂

Cheers

PS. If you want to send me a clip with you saying “.com”, you know where I am.

Video : Hybrid Partitioned Tables in Oracle Database 19c

In today’s video we’ll give a quick demonstration of Hybrid Partitioned Tables, introduced in Oracle Database 19c.

The video is based on this 19c article.

The video only has a single example using external partitions pointing to CSV data. The article also includes and example using a Data Pump file.

Video : Using Podman With Existing Dockerfiles (Oracle Database and ORDS)

Today’s video shows me using some of my existing Docker builds with Podman. Specifically a 19c database container and an Oracle REST Data Services (ORDS) container.

For those with an understanding of Docker, it should look really familiar, but it does introduce a twist in the form of a pod.

The video is based on this article.

You can see more information about containers here.

The star of today’s video is Bart Sjerps. It was really hard to find a piece of this recording that didn’t have James Morle wittering over everyone on it. 🙂

Oracle Database 19c on Fedora 32

Fedora 32 was released at the end of April (see here). Here comes the standard warning.

Here are the usual things I do when a new version of Fedora comes out.

I pushed a Vagrant build to GitHub.

So now you know how to do it, don’t. 🙂
