Hide and Seek with RU 19.18.0

One and a half weeks ago we released the Database and Grid Infrastructure Release Updates (RU) 19.18.0. You could read on the blog how to apply it, and you could read also about an alert. So far, all was more or less transparent but apparently sort of an Hide and Seek with RU 19.18.0 has happened. So let me shed some light.

Heads Up!

I am just the messenger trying to bring some light into the topic. Neither is our team responsible nor do we have any sort of control on this process. I …

MRP3 for Oracle 19.17.0 adds an interesting surprise

You may have read my previous blog posts about MRPs (Monthly Recommended Patches). And today I did a quick check with Rodrigo. We both were a bit surprised to have the MRP3 for 19.17.0 add a lot of fixes to a standard RDBMS installation. So we were investigating a bit further. As a teaser, read on to see that MRP3 for Oracle 19.17.0 adds an interesting surprise.

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.

Gagan Singh, Enterprise Architect at Intel, shared it with me last week. The goal was to upgrade from Oracle 11.2.0.4 to Oracle 19c with the least amount of downtime …

Binary patching is slow because of the inventory

Posted on May 10, 2022 by Mike.Dietrich Patch Recommendation 52

The headline of this blog post may sound a bit cryptic: Binary patching is slow because of the inventory. But actually this seems to be one of the main causes when your binary patching gets slower and slower with every patch you apply.

The more you patch, the worse it gets

Well, this is a tough headline. But you may have read my blog posts about my quarterly patching experience. It actually started with the July 2021 RU in my 19c environment when I wrote:

At least in my environment, both checks with the

Oracle Database 12.2.0.1 – End of Support and Patch Bundles

Posted on April 26, 2022 by Mike.Dietrich Release Schedule 1

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.

Some additional information regarding the Oracle 19.14.0 RUs

Posted on January 27, 2022 by Mike.Dietrich Patch Recommendation 27

You may have read my previous blog post about patching all my environments to the January 2022 patch bundles. But since I do this in a very simple non-RAC, non-GI environment, I may not see issues you may have encountered. Some people commented – and I would like to share Some additional information regarding the Oracle 19.14.0 RUs . Still, please, this is NOT a collection of all open issues. I just see this blog post as a summary of the issues I have seen and/or heard about so far.

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 …

Which database version can be used with Grid Infrastructure 19c?

Posted on October 6, 2020 by Mike.Dietrich ASM / RAC / GI 25

This will be a very short blog post today. But a colleague asked me this question just a few minutes ago: Which database version can be used with Grid Infrastructure 19c? And I realized that I neither put it on the blog yet nor did I bookmark it. But I answered this question several times already.

There are 4 sources I did check:

MOS Notes on MyOracle Support

At first, I answered with MOS …

Do you need to apply OJVM patches to Grid Infrastructure?

Posted on January 24, 2020 by Mike.Dietrich ASM / RAC / GI Patch Recommendation 18

From time to time, when I discuss OJVM patching with customers, I hear the following question: Do you need to apply OJVM patches to Grid Infrastructure? I’m carrying around this topic since months actually.

Do you need to apply OJVM patches to Grid Infrastructure?

A quick MOS check

Well, you’d assume this is something MOS does give you an answer within fractions of a second. But nope. I found a lot but unfortunately not what I was looking for. What I found instead where community discussions where applying OJVM patches to a 12.1.0.2 GI installation corrupted the inventory. Hence, there seems to be some …

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;

Oracle 12.2.0.1 RESTART: Make sure you’ve patched your Oracle 12.1.0.2 homes

Posted on August 31, 2017 by Mike.Dietrich Restart - SIHA - HAS 10

This blog post title sounds a bit weird, doesn’t it? Oracle 12.2.0.1 RESTART: Make sure you’ve patched your Oracle 12.1.0.2 homes. Why the heck should you patch your 12.1.0.2 database homes upfront?

Oracle 12.2.0.1 RESTART: Make sure you’ve patched your Oracle 12.1.0.2 homes

Well, there’s an interesting issue happening. When you work with Oracle Grid Infrastructure, no matter if you operate a cluster or “just” use Oracle Restart, you’ll have to upgrade GI to Oracle 12.2 first before you can manage 12.2 databases with it. That’s not new. It’s a well understood rule.

Now guess you operate Oracle RESTART (SIHA …
