Oracle 12c SE2 RAC support on Clusterware after upgrade to 19c

hillrudy

Hi,

In order to test our application on 19c EE, I must upgrade a 12c Clusterware with some 12c SE2 RAC databases running on it to 19c.

What I want to end up with is a 19c Clusterware running on 2 nodes, all the old 12c SE2 RAC databases running on it, then create a new 19c EE RAC database on top of it.

I'm all set to start the rolling Clusterware upgrade to 19c, but will all the 12c SE2 RAC databases be compatible with 19c Clusterware after the upgrade?

I'm asking this because of "Desupport of Oracle Real Application Clusters (RAC) with Oracle Database Standard Edition 19c" 2504078.1.

Can you help me?

Thanks,

Rodolfo

There isn't a 19c RAC license for SE2 anymore (also no RAC OneNode).

But you should be able to run older SE2 RACs (12.1/12.2) with GI 19c:

https://docs.oracle.com/en/database/oracle/oracle-database/19/cwlin/general-restrictions-for-using-earlier-oracle-databa…

It even should work with 19c GI and 11g RAC:

https://docs.oracle.com/en/database/oracle/oracle-database/19/cwsol/configuring-earlier-releases-oracle-databases-on-ora…

"From the 11.2 Oracle Database home, run Oracle Database Configuration Assistant (DBCA) and create the Oracle RAC Database, using Oracle ASM as storage for the database data files."

Hi,

please see the MOS note "Oracle Clusterware (CRS/GI) - ASM - Database Version Compatibility (Doc ID 337737.1)", which will tell you that 19c Grid Infrastructure and 12c database is supported.

As Joerg mentioned, RAC is not available with 19c SE2 anymore (RAC One Node has never been available for SE2).

Some time ago, Oracle announced that there will be another HA solution for SE2 (https://blogs.oracle.com/maa/standard-edition-2-announcing-standard-edition-high-availability ) but it hasn't been released yet.

Update:

"Standard Edition High Availability" (SEHA) was released with the RU 19.7 of the Oracle Database.

Please see the announcement https://blogs.oracle.com/maa/standard-edition-high-availability-officially-released  or my blog post https://www.markusdba.net/2020/05/11/standard-edition-high-availability-first-impressions/  with some first impressions.

Hi, I want to understand if "Is Oracle RAC for 19C supported on VMware?"

The reason, why I am asking, is currently we have 10G on a RAC but the underlying servers are physical.

We will be moving those servers to VM on a VMWare ESX cluster. Want I want to know is if we migrate to a 19C ( which is hte plan) then can we establish a similar RAC set up in the new ESX Cluster or should we use Oracle Clusterware to stand up the RAC for the 19C DB?

Thanks
