And the DB_UNIQUE_NAME of the CDB will be

the default service name registered by the CDB

. With this rule, it must be possible to have the exact same name for the CDB(the DB_NAME)and the PDB, considered that we have set a different DB_UNIQUE_NAME. How do I understand the size of my pluggable database?Check the Size of Oracle Database and PDB databases select amount( bytes )/ 1024/1024 size_in_mb from dba_data_files;
