How to grant SYSDBA access to users on Oracle Cloud v19c It seems that you can't grant SYSDBA access to users on oracle cloud. I am using v19c, when trying to alter roles through the web &quot;Database Actions&quot; interface, the only roles I see are; CDB_DBA DBA LBAC_DBA PDB_DBA. How can I make a user SYSDBA?
In short, you can't. You need to use PDBADMIN user or PDB_DBA role for such things: https://docs.oracle.com/en-us/iaas/exadata/doc/eccmanagingdatabases.html
Also there is a very useful document:
Known Issues for Oracle Database Exadata Express Cloud Service
It gives some more internal info about cloud access and privileges.
