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.

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 …

AutoUpgrade may run into a timeout when GI is lower than 19.10.0

Posted on June 21, 2021 by Mike.Dietrich ASM / RAC / GI Patch Recommendation 9

The other day I received a question from a colleague about the risk of having GI and database both not being on the same RU. And a long while ago I blogged about it. We recommend that you keep it in synch. But you don’t have to. At the same time I received a wish from Ernst Leber to post something on the blog he and his colleague had trouble with when upgrading to 19c in a RAC environment. AutoUpgrade hung. But he titled his email with “not an AutoUpgrade problem!”. Still I agree, it is worth to write …

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.

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.

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

Posted on June 11, 2020 by Mike.Dietrich ASM / RAC / GI 2

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?

GI Patch 28553832 may be needed before you upgrade to 19c

Posted on January 7, 2020 by Mike.Dietrich ASM / RAC / GI Flaws and Pitfalls 8

Thanks to my colleague Sebastian Alasino who works in the MAA team out of the UK. Sebas highlighted this issue to. And I’d like to share it with you when you attempt to upgrade Grid Infrastructure to Oracle 19c. If you have the Docker RPM installed and you were lazy on patching, then GI Patch 28553832 may be needed before you upgrade to 19c.

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.

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 …

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 …

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.

In addition please see the …
