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.

What is the issue?

If the Docker Engine RPM is installed and your GI version is 12.1.0.2, 12.2.0.1 or 18c below a certain patch level, the CSSD demon fails to …

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

Patch RecommendationI’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.

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

Yes, you can have a higher version PSU or BP in the Database home than in the Grid Infrastructure home managing the resources. This is implicitly documented in MOS Note 337737.1 –

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

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?

In addition please see the
