Intel uses AutoUpgrade to upgrade from Oracle 11.2.0.4 to 19c

Posted on September 27, 2022 by Mike.Dietrich Customer Success 14

Funny, I was traveling recently with RAC PM Anil Nair – but he forgot to tell me that this cool story has been published just a few days before we took of for YATRA 2022 to India: Intel uses AutoUpgrade to upgrade from Oracle 11.2.0.4 to 19c. I know that Anil is simply so busy – and my surprise was huge.

Posted on March 25, 2022 by Mike.Dietrich AutoUpgrade 40

Many of you have used AutoUpgrade for your database upgrades already. Just a few days ago I received some almost enthusiastic comments which made me very very happy. And if you thought it can’t get any better, no worries: AutoUpgrade 2.0 has been released – and got reuploaded.

Why AutoUpgrade 2.0?

As you know, we don’t do marketing but just talk tech. But you may have also recognized that we slowed down in our agile release cycle for AutoUpgrade. The simple reason for this long period of silence was that we’ve had a …

Oracle Database 12.2.0.1 and GI are certified on OL8 and RHEL8

Posted on December 14, 2021 by Mike.Dietrich Operating System 4

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 …

Data Pump Super Patch for Oracle 19.10 and newer

Posted on April 15, 2021 by Mike.Dietrich Data Pump Patch Recommendation 64

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.

Why do you need this patch?

Many customer will know the issue that adding changes with datapatch may take a long time as soon as dpload.sql is involved. And this …

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

Posted on November 13, 2020 by Mike.Dietrich ASM / RAC / GI Flaws and Pitfalls Patch Recommendation 11

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.

Collection of EBS upgrade information for Oracle Database 19c

Posted on June 30, 2020 by Mike.Dietrich E-Business Suite 0

This was the question I received the most often during the Virtual Classroom web seminars 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.

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

Posted on May 14, 2020 by Mike.Dietrich Operating System 39

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.

Do we offer patched Gold Images already?

Posted on January 28, 2020 by Mike.Dietrich Installation 9

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

Posted on July 19, 2019 by Mike.Dietrich AutoUpgrade 51

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.

Where does the database link SYS_HUB come from?

Posted on September 24, 2018 by Mike.Dietrich ASM / RAC / GI Flaws and Pitfalls 6

This blog lives a lot from customer’s feedback and updates. And these days, Nicolas Jardot from dbi-services in Switzerland sent me an email asking: Where does the database link SYS_HUB come from? And if he can delete it or if it has any deeper purpose. Neither Google nor MOS reveal a lot of useful information

Where does the database link SYS_HUB come from?

I took my vanilla 18.3.0 database in our hands-on lab and check:

column owner format a5
column db_link format a12
column username format a12
column host format a12

select con_id, owner, db_link, username, host from cdb_db_links;

DBCA 12.2 does not update /etc/oratab in GI / RAC

Posted on December 20, 2017 by Mike.Dietrich ASM / RAC / GI Behavior Change 12

Interesting things happen. And I learned (credits to Arun Gupta and others) that there is a change in Oracle Database 12.2 environments I wasn’t aware: The DBCA 12.2 does not update /etc/oratab in GI / RAC environments. Let me give you some extra information and hints on this topic as it may cause some strange situations.

DBCA 12.2 does not update /etc/oratab in GI / RAC

Arun Gupta commented on the blog:

Another case in point. DBCA fails to update the /etc/oratab file in 12.2 when a database is created. There is no documentation of this behavior. So, I opened

Oracle RESTART deprecation announcement got withdrawn

Posted on July 31, 2017 by Mike.Dietrich Restart - SIHA - HAS 4

Very good news for all customers using Oracle RESTART:
The Oracle RESTART deprecation announcement got withdrawn.

I have blogged in the past several times about Oracle RESTART of course either regarding upgrade, downgrade and patching:

And one of the customers I work with for quite a while, Swiss Mobiliar Insurance uses Oracle RESTART for all their Oracle Database environments:

Keep your patch versions between Grid Infrastructure and Databases Homes in synch

Posted on April 26, 2017 by Mike.Dietrich ASM / RAC / GI Patch Recommendation 10

Keep your patch versions between Grid Infrastructure and Databases Homes in synch I’ve had some interesting discussions with Anil Nair, our RAC Product Manager and a customer in the past days. The customer was looking for a definite statement that they can have a higher version of Patch Set Updates (PSUs) or Proactive Bundle Patches (BPs) in the Database homes than in the Grid Infrastructure home managing the resources.

For Oracle Database 18c, 19c and onward, please read instead:

Can you have different PSU/BP versions between Database and GI homes?

Yes, you can have a higher version PSU …

Upgrade the Operating System in a RAC Environment

Posted on February 23, 2015 by Mike.Dietrich ASM / RAC / GI 25

Last week at the upgrade workshop in Budapest a customer had a interesting and – I believe – not uncommon question.

“How can I upgrade my Linux Operating System in my RAC environment without taking the entire cluster down?”

In this specific case the customer wanted to upgrade from RHEL 5.10 to RHEL6 or RHEL7.

Let’s assume it’s the typical 2-node-RAC where one wants to upgrade in a rolling fashion. And the data is stored within ASM.

Drain Node 1 (i.e. take the workload off) – this will be the node getting upgraded first
Remove Node 1 from the cluster

Grid Infrastructure PSU Jan 2015 – Am I too intolerant?

Posted on February 18, 2015 by Mike.Dietrich ASM / RAC / GI Patch Recommendation 6

Germans are not only known for being precise and timely – but sometimes also for being too direct. Well, Roy could tell you stories … and I always honor his politeness 🙂

Enough about stereotypes. I work with a customer at the moment on their 12c upgrades. And I did recommend the most recent PSU (Patch Set Updates) for their Grid Infrastructure environments running Oracle Restart. Same of course for the database homes but this blog post will just name some findings I’ve had the other night when trying to apply the January 2015 GI PSU to my …

Grid Infrastructure Management Repository (GIMR) database now mandatory in Oracle GI 12.1.0.2

Posted on August 22, 2014 by Mike.Dietrich ASM / RAC / GI Oracle Database 12c 30

During the installation of Oracle Grid Infrastructure 12.1.0.1 you’ve had the an option to choose YES/NO to install the Grid Infrastructure Management Repository (GIMR) database MGMTDB – but as of Oracle 12.1.0.2 Grid Infrastructure Management Repository (GIMR) database now mandatory in Oracle GI 12.1.0.2:

Grid Infrastructure Management Repository (GIMR) database now mandatory in Oracle GI 12.1.0.2

GIMR database now mandatory in Oracle GI 12.1.0.2

With Oracle Grid Infrastructure 12.1.0.2 this choice has become obsolete and the above screen does not appear anymore. The GIMR database has become mandatory.

What do we stored in the GIMR?

You’ll find it in the Oracle 12.1.0.2 documentation via this link.

PSU1 and PSU2: Datapatch Issues coverd in MOS Note

Posted on March 5, 2014 by Mike.Dietrich Patch Recommendation 2

You may have read a posting dis-recommending PSU1 and PSU2 for Oracle Multitenant 12.1.0.1 especially in RAC/GI environments earlier this week. Actually following a lot of internal discussions I will post some advice and clarification later this week.

Now I have an useful update:
Datapatch Issues are covered within a separate MOS Note making it easier to keep track and find workarounds for known issues.

Upgrade to Grid Infrastructure – but OCR and VOTING on RAW?

Posted on March 4, 2014 by Mike.Dietrich ASM / RAC / GI 0

Just received this question from a colleague these days:

“The current customer environment is 10.2.0.5 on Linux with a 2 node RAC cluster having OCR and Voting Disks on RAW devices. Customer is concerned about the possibility of upgrading to 11gR2 Grid infrastructure first before they could upgrade to 12c Grid
infrastructure.”

Now the answer is written down in MOS Note 1572925.1:
How to Upgrade to 12c Grid Infrastructure if OCR or Voting File is on Raw/Block Devices

Basically the MOS Note says:
You will have to relocate your OCR/Voting to a supported device BEFORE you can upgrade …
