1. In the DBA view, connecting to the CDB root of a RAC database and expanding the 'Container Database' menu, each PDB is shown for every instance (select from gv$pdbs). Clicking on PDB to see the details, there is no indication which instance it corresponds to.
2. Creating a new PDB in a RAC multi-tenant database give ORA-1427 for every character typed in the new PDB name (again, selecting from gv$pdbs returns a row for each instance - probably want a 'distinct' somewhere...)
3. expanding the Storage->datafiles menu shows the datafiles and tempfiles for the CDB root ***plus the tempfiles for all the PDBs***, but clicking on datafiles only shows the datafiles and tempfiles for the CDB root
