Upgrading to GI 23ai at ExaCC using CLI

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).

Again, first things first. Requirements

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.

Upgrading to GI 23ai at ExaCC

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:
