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

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.

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

There are 4 sources I did check:

  • MOS Notes on MyOracle Support
  • Oracle Documentation
  • Certification Information on MyOracle Support
  • Database Upgrade Blog

At first, I answered with MOS

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?

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

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

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

Oracle 12.2.0.1 RESTART: Make sure you've patched your Oracle 12.1.0.2 homesThis 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

Keep your patch versions between Grid Infrastructure and Databases Homes in synchI’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

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

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?
