Recently I shared several posts about the process to upgrade the GI from 19c to 23ai at ExaCC. My last post summarizes a lot of this, please read it here. But as you know, to use the 23ai you need to be running with OEL 8, and for ExaCC, the upgrade is quite simple. The goal is to reach this, “no updates” and “System up to date”:
The 23ai is already available at Cloud and ExaCC as well. It is On-Prem, but it is Cloud too, so, we can use it. Recently I needed to create some databases manually (not using the ExaCc dbaas* utilities) and encountered some interesting details when using dbca. Mainly because at Cloud we are forced to have encrypted databases. You can skip directly to the end to see how to solve and create databases with TDE enabled since the beginning when using dbca, or read the rest of the post to check the root cause and the troubleshooting.
Just to remember, if you want to create a database using the dbca, you have a lot of options but nothing related to TDE:
[oracle@o8p1-19c ~]$ which dbca /u01/app/oracle/product/19.18.0.0/dbhome_2/bin/dbca [oracle@o8p1-19c ~]$ [oracle@o8p1-19c ~]$ dbca -silent -createDatabase -help |grep -i TDE [oracle@o8p1-19c ~]$
So, when I tried to create the database with dbca I tried to use it with the same parameters that I used in all my previous years. But it failed telling that “ORA-28361: Master key not yet set”:

As you know, the 23ai is already available in several environments, mainly in Oracle Cloud, and one of these is the ExaCC. I already covered how to do the upgrade to 23ai for Grid Infrastructure (GI) using the Web interface, and Christian covered the upgrade of the OCI CLI. But here I will upgrade using the ExaCC CLI (dbaascli).
As discussed in the previous post, the first requirement is that your VM/domU is running the 23.1x version because it runs over the OEL 8. The second one is that the only available versions that are allowed to be installed in the cluster are the 19c and 23ai. The last one is that the attribute “compatible.rdbms” needs to be at least 19.0.0.0 for your diskgroups:
SQL> SELECT name, compatibility, database_compatibility FROM v$asm_diskgroup; NAME COMPATIBILITY DATABASE_COMPATIBILITY ------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ DATAC5 19.0.0.0.0 11.2.0.4.0 RECOC5 19.0.0.0.0 11.2.0.4.0 SQL> SQL> ALTER DISKGROUP DATAC5 SET ATTRIBUTE 'compatible.rdbms' = '19.0.0.0.0'; Diskgroup altered. SQL> ALTER DISKGROUP RECOC5 SET ATTRIBUTE 'compatible.rdbms' = '19.0.0.0.0'; Diskgroup altered. SQL>
The 23ai was released last month and was only available at Oracle Cloud deployments and a few places for free edition, nothing besides that. Last year it was also released (focused on the Devs) as a formerly 23c free edition. Fortunately, it was released to be used at ExaCC. So, now we can upgrade Grid Infrastructure (GI) and install the database to play with it.
In all previous scenarios, we had some constraints. For Dev’s we didn’t have RAC, DG, and GI features at all. And for OCI, we didn’t have access to manually create databases or deploy GI buy ourselves. For ExaCC we are free to deploy our GI, install RAC databases, and so on. Here I will show how to upgrade your GI from 19c to 23ai. We will reach this:
