Usually, when many people export a certain part of data under pdb, they use service_name custom tns to locate and connect to a certain pdb. However, 12C has one of the following methods to connect to pdb, which is much more convenient:

Alter session set container=xxx

Select * from global_name; if the global_name=aaa queried in this step

Export ORACLE_SID=lych

Expdp lych/qwezxc@hostname:1521/aaa.

Sometimes you may need to use sys to import the whole database. This involves escaping:

Impdp\ 'sys/aaa000@hostname:1521/aaa as sysdba\'.
