Your Oracle 12c multitenant container database (CDB) contains multiple pluggable databases (PDBs). In the
PDB hr_pdb, the common user c##admin and the local user b_admin have only the connect privilege.

You then execute the commands:
SQL> GRANTc##role1 TOcMadmin CONTAINER=ALL;
SQL>CONNsys/oracle@HR_PDB assysdba
