Oracle Database 12.2.0.1 – End of Support and Patch Bundles

This will be a short blog post but since I received a number of messages yesterday after I published my usual Patching all my environments with the April 2022 Patch Bundles blog post I need to clarify a few things regarding Oracle Database 12.2.0.1 – End of Support and Patch Bundles.

Premier Support for Oracle 12.2.0.1

If you remember this, the Premier Support period for Oracle 12.2.0.1 ended on November 30, 2020.

Limited Error Correction Support for Oracle 12.2.0.1

Since many of you were still on Oracle 12.2.0.1 when the end of Premier Support …

Why you can’t stay on Oracle Database 11g forever

Oracle Database 11g? In 2022? Yes, I know – and you know too – there are Oracle 11g databases out there in production. And blindly I’d say: Too many. Of course, we are the “upgrade guys” trying to convince you to move to Oracle Database 19c. And I bet, for each of your 11g databases there’s a valid and legit reason why they haven’t upgraded yet. But there is one often neglected technical reason Why you can’t stay on Oracle Database 11g forever. So let me explain this below.

Patching all my environments with the January 2022 Patch Bundles

It’s patching time. When I checked an SR and had a quick discussion with a customer yesterday, Peter reminded me that it’s patching day. And at about 20:00h CET the new patch bundles appeared on MOS. So let me show you again Patching all my environments with the January 2022 Patch Bundles for 11.2.0.4, 12.2.0.1, 19c and 21c.

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

Patching all my environments with the October 2021 Patch Bundles

My calendar has no error or NLS conversion issue – I was just way to busy the past two months with seminars. But today a colleague asked me whether my 21.4 install reports a 21.3 Build Label in the trace files. And this reminded me that I should now finally apply the patch bundles from October 2021 to our Hands-On Lab environment. So again, another blog post about Patching all my environments with the October 2021 Patch Bundles.

Oracle Database 12.2.0.1 and GI are certified on OL8 and RHEL8

No worries, this isn’t a blog post from the vault. And I haven’t accidentally published something from the past just today. It is real. Oracle Database 12.2.0.1 and GI are certified on OL8 and RHEL8.

What has been certified?

Thanks to my colleagues and a large customer in the UK, I received an email asking whether I have seen this information already on MOS. I haven’t. I knew that there were discussions but I had no actual date for the 12.2.0.1 certification on OL8 on my radar.

So in brief, these Linux 8 releases …

Patching all my environments with the July 2021 Patch Bundles

It’s patching day again. Hurray! Or not. I realize that at patching day, the 19c bundles are all missing. So wrote this blog post a bit after the usual release day. In my case this will include Oracle 19.12.0 RU and the July 2021 RU for Oracle 12.2.0.1. Please find the details about Patching all my environments with the July 2021 Patch Bundles below.

Where are AutoUpgrade error codes documented?

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 …

No RURs for 12.2.0.1 – and Oracle 11.2.0.4 left Extended Support

Last week I blogged about the quarterly patching fun when applying the Release Updates to my environments. But I completely forget to mention and explain a few things. There are No RURs for 12.2.0.1 – and Oracle 11.2.0.4 left Extended Support.

Why Cool Features for DBAs?

Actually the idea is not new. And we’ve included some slides into our workshops already for quite a while. But there are simply too many cool features. Our focus is in features which usually don’t make it into advertising or …

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 …

Does Data Pump import only serially into PDBs?

Daniel and I did Web Seminars this week. One of them was about the different migration strategies. We did talk a lot about Data Pump. One attendee mentioned that Data Pump Import does not work parallel into PDBs in Oracle 12.2.0.1 and Oracle 18c. We were skeptical, and today I tried out to check: Does Data Pump import only serially into PDBs?

Very simple test setup

For this test, I take a schema export from an 11.2.0.4 database in our Hands-On Lab, the TPCC user HammerORA uses in the UPGR database.…

Oracle Database 12.1.0.2 certified on Oracle Linux 8 and RHEL8

The other day I received a question on Twitter regarding my experience with Oracle 12.1.0.2 on Linux 8. I first thought this may be an error. Why should Oracle 12.1.0.2 been certified on Linux 8. And I didn’t see anything internally about Oracle Database 12.1.0.2 certified on Oracle Linux 8 and RHEL8.

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?

Oracle 12.2.0.1 – Clarification for Limited Error Correction Support

A few weeks ago, you read the announcement of the availability of Limited Error Correction Support for Oracle Database 12.2.0.1. But many of you had some questions right away. I could answer most of them easily. But it was clear to us that there was more information needed. Hence, we published more information for Oracle 12.2.0.1 – Clarification for Limited Error Correction Support.

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

Oracle Multitenant: Be aware of the silent COMPATIBLE change

This topic is included in our Multitenant slides for a long time. But whenever I want to point somebody to the blog post, I realize that it’s not on the blog yet. Actually I discussed this topic recently during a customer visit again. It’s time to put it on the blog. When you use Oracle Multitenant: Be aware of the silent COMPATIBLE change.

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?

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?

AutoUpgrade and Data Guard, RAC, Restart and non-CDB to PDB

I need to bring this blog post forward about AutoUpgrade and Data Guard, RAC, Restart and non-CDB to PDB. Initially I planned to write this a bit later. But some of you had questions or were wondering why AutoUpgrade hasn’t done certain tasks. Hence, I’d like to clarify what AutoUpgrade can do, what it can’t and what you’ll have to do at the moment.

I refer to the AutoUpgrade tool as of July 2019. In later versions, one or the other restriction may be lifted. I will blog about it then as well.

Behavior Change in Oracle 18c/19c: No symbolic links for Data Pump directories

Most of you may have recognized the desupport of UTL_FILE_DIR with Oracle Database 18c. Reason is mostly that UTL_FILE_DIR opens a lot of possibilities to do insecure things. But this has another effect which may not be obvious to you. There’s a behavior change in Oracle 18c/19c: No symbolic links for Data Pump directories. Read further to learn more about it.

UTL_FILE_DIR Desupport

In Oracle Database 18c we announced the desupport of UTL_FILE_DIR initialization parameter. But as you can read as well in the Database Upgrade Guide, there’s this remark:
