Com o root container, as views cdb_tablespaces e cdb_data_files mostra as tablespaces e datafiles de todo container no CDB.
Quando conectado a um PDB, as views cdb_tablespaces e cdb_data_files mostram as mesmas informações que as views dba_tablespaces e dba_data_files para o PDB.

Como verificar Local Undo no Oracle 12 release 2
No Oracle Database 12c Release 1, todos os containers em uma instância compartilha a mesma tablespace de UNDO.
No Oracle 12c Release 2, cada container em uma instância pode usar sua própria tablespace de UNDO.
