In Oracle 21c Express Edition, I want to create a pluggable database named XE, which failed due to conflict with the existing service name in CDB or PDB.
Is there any way to delete or change the default service name XE?
I tried the command but it created a new service named SomethingElse and the default service XE is still there.
ALTER SYSTEM SET SERVICE_NAMES = 'SomethingElse'
