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. SQL>
