Upgrade Webinars 2020 – Recap and Videos on-demand

Thank you for participating in our 4 Database Upgrade to Oracle 19c webinars in the past two weeks. There were over 800 questions during the webinars – and it was a good idea that we prerecorded them. This way, I could answer your questions as it was a more convenient time for me than for Roy. We enjoyed it a lot – and from the feedback I read, most of you enjoyed it, too. Now please read about Upgrade Webinars 2020 – Recap and Videos on-demand below.

Collection of EBS upgrade information for Oracle Database 19c

This was the question I received the most often during the Virtual Classroom webinars last week: “Can you say something about EBS upgrades with 19c?”. And I promised to publish a blog post about it. But as I’m not an EBS expert, I can only share a Collection of EBS upgrade information for Oracle Database 19c. For all further inquiries, please open an SR or get in touch with your Oracle contact.

Oracle Long Term Support vs Innovation Releases

Earlier this week I wrote about the recent exciting news: Oracle Database 19c Premier Support extended by more than 1 year. But if you went to MOS 742060.1 to read the fine print, you may have spotted another change as well: A differentiation between Oracle Long Term Support vs Innovation Releases.

What is a Long Term Support Release?

MOS 742060.1 explains:

Oracle Database Long Term Releases are ideal for use cases that benefit from less frequent upgrades to newer releases. Long Term Releases offer the highest level of stability and the l

Does your GI RU/RUR patch level has to match your database’s?

A long while ago I blogged about whether you should keep your patch versions between Grid Infrastructure and Databases Homes in synch, or not. And today, Daniel dropped me a note mentioning that this old blog post may need an update for 18c/19c. He’s right. And as I’ve had trouble finding my old blog post, I title this one a bit more obvious: Does your GI RU/RUR patch level has to match your database’s?

DBMS_JOB one-off patch needed for Oracle 19.3.0 – 19.7.0

A while ago I blogged already about this behavior change for DBMS_JOB in Oracle Database 19c. Many of you are aware of this. But today I learned something new about it. Kudos to Alexey Makhmutov for bringing this to my attention. There is a very important fix you will need on top in 19c to avoid performance issues. If you rely on jobs with the old job interface, take note: DBMS_JOB one-off patch needed for Oracle 19.3.0 – 19.7.0

AutoUpgrade and Plug In to a CDB – with a single command (and video)

I have to confess, this feature is out and available for quite a while. But only unofficially. AutoUpgrade can upgrade and plug in a non-CDB into a CDB. But it lacked flexibility. And we didn’t test it a lot. Hence, you could find it documented in our Hands-On Lab instructions. And we did this exercise with you already in our sold-out labs at OOW 2019 as well. But since a week and a bit, it is officially supported: AutoUpgrade and Plug In to a CDB – with a single command (and video).

Of course, Oracle Clusterware is certified on OL8/RHEL8 as well

To be very honest, when I posted a few days ago, Oracle Database 19c is certified on OL8/RHEL8 I didn’t check for the Oracle Clusterware (OCW) certification. I blindly assumed that this is the case. But from comments and discussions on twitter, I realized it may be necessary to point this out explicitly to avoid confusion. Even though my fellow mate, RAC Product Manager Anil Nair has pointed it out already many times: Of course, Oracle Clusterware is certified on OL8/RHEL8 as well.

Oracle Database 19c is certified on OL8 and RHEL8

Oh … I’d say this was the question I’ve got asked the second most often in the past months (after a potential extension for Oracle 12.2.0.1 support): When will Oracle certify OL8 and RHEL8? And I read this question internally even more often. Now thanks to my team mate Daniel Overby Hansen who spotted it on Twitter on the weekend, we can tell you that … finally … drum roll … Oracle Database 19c is certified on OL8 and RHEL8.

Upgrade Testing with a Refreshable PDB – does this work?

Yesterday, Daniel pinged me to discuss an upgrade testing scenario I had evaluated briefly by myself a while ago. I can’t remember why I gave up. But Daniel had some great ideas and tried already a lot in our OCI cloud. We want to use a refreshable PDB. And keep it up to date, then upgrade it. The idea of this approach: Whereas a CLONE or RELOCATE uses the initial command as the marker, a REFRESH would allow me to be way more in synch. So the question is: Upgrade Testing with a Refreshable PDB – does this work?

Oracle Database Upgrade – Quick Start Guide available

AutoUpgrade and the COMPATIBLE parameter

Several times I’ve got asked by customers if AutoUpgrade does change the COMPATIBLE parameter. So let me explain what happens to COMPATIBLE when you upgrade. And give you also some hints about AutoUpgrade and the COMPATIBLE parameter.

AutoUpgrade and the COMPATIBLE parameter

Does AutoUpgrade change COMPATIBLE?

No. Clearly, AutoUpgrade does not change the COMPATIBLE parameter for several reasons. At first, we recommend to not change the COMPATIBLE parameter right after the upgrade if you can afford another downtime soon after. By keeping COMPATIBLE on the previous (before upgrade) value, you have the choice to revert back to the previous …

Upgrade Testing – Online Clone a PDB to 19c

In the past I wrote some articles about cloning PDBs to new environments. And I added a post about RELOCATE as well. But I realized that I have no specific blog post about a very typical scenario: Upgrade Testing – Online Clone a PDB to 19c.

My Setup

I have an Oracle 12.2.0.1 CDB with a PDB, and another Oracle 19.6.0 CDB. I will hot clone the PDB from 12.2.0.1 to the higher version CDB, and then upgrade the PDB.

Is Oracle Fail Safe 4.2.1 certified with Oracle Database 19c?

From time to time I get questions regarding the certification of Oracle Fail Safe. And just the other day, a customer asked: Is Oracle Fail Safe 4.2.1 certified with Oracle Database 19c? I briefly browsed my blog posts about Oracle Fail Safe from the past, and even though I mentioned that the certification for 4.2.1 on Oracle 12.2.0.1 may apply to later versions, I never updated it.

APEX is invalid after upgrading to 12.2 – ORA-20001

We are running the AutoUpgrade-for-RAC beta test since last week. And the first issue one customer encountered … is neither an AutoUpgrade nor a RAC issue. It has to do with APEX and SPATIAL, and missing grants. APEX is invalid after upgrading to 12.2 – ORA-20001

Upgrade PDBs with RELOCATE – How does it work?

Today Roy and I received a question from a colleague about the RELOCATE feature in Multitenant. And I’d like to shed some light and this topic a bit more. Upgrade PDBs with RELOCATE – How does it work?

Upgrade PDBs with RELOCATE - How does it work?

Photo by Sebastian Pena Lambarri on Unsplash

RELOCATE and UPGRADE?

At first, it looks very promising to me. RELOCATE uses the HOT CLONE functionality of Multitenant but then relocates the PDB from one to another CDB. You need to fulfill a few important requirements, for instance:

  • Local Undo must be enabled in both CDBs
    • This limits the technique to at least Oracle

Do we offer patched Gold Images already?

Internally we can use a Gold Image service at Oracle. I can download a zip with 19.6.0 included. But externally for you as customers, the download of 19.6.0 required that you download 19.3.0 at first, then apply 19.6.0 on top of it. But a day ago, a tweet by my Belgium friend Philippe Fierens caught my attention. Do we offer patched Gold Images already?
