Sql Developer can conect Oracle Database 12c with TNS but can not connected with basic

Question

I have installed a new oracle database(12.2.0.1). I have create a pluggable database (orclpdb). I create a user Fed_Test_User in the PDB. And I can connect it by SQL developer with TNS(can connect by conn Fed_Test_User/welcome@orclpdb). But I can not connect by SQL Developer with basic connection type.

Listener.ora:

 LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

sqlnet.ora:

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

tnsnames.ora:

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.us.oracle.com)
    )
  )


ORCLPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME =orclpdb.us.oracle.com)
    )
  )

lsnrctl status:

anything I missed? Hope someone can help me. Thanks;

Answer 1

When connecting to the PDB, you must use the SERVICE name.

The SID is for the container database only.

See this page, specifically working with PDBs

Service Name. When you create a PDB, Oracle automatically adds it as a service in the listener. You can confirm it by looking at the listener status: 

[oracle@prosrv1 trace]$ lsnrctl status

The service "pdb1" actually points to the PDB called PDB1. It's very important to note that that this is not a service name in initialization parameter of the database, as you can see from the service_names parameter of the database.

SQL> show parameter service
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
service_names string CONA
You can place that service name in an entry in the TNSNAMES.ORA file:

PDB1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prosrv1.proligence.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PDB1)
)
)
Now you can connect to PDB1 using the connect string:

[oracle@prosrv1 ~]$ sqlplus system/oracle@pdb1

Answer 2

connect with TNS

connect with basic

By the way. I can connect the CDB by the SQL developer with basic connection type.

connect CDB with basic
