sqlplus can not connect to oracle using information in tnsnames.ora

Question

I can login by

sqlplus / as sysdba

then I start the intance using startup, I also can start PDB using

startup pluggable database pdborcl 

In the terminal, echo $ORACLE_SID gets ora12cr1

But I cannot login by using

sqlplus  /@ora12cr1 as sysdba

I got ORA-01017: invalid username/password; logon denied. Below is my tnsnames.ora:

ORA12CR1=
  (DESCRIPTION=
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    (CONNECT_DATA=
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.cn.oracle.com)
    )
  )

PDBORCL =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
     (CONNECT_DATA =
       (SERVICE_NAME = pdborcl.cn.oracle.com)
     )
 )

The oracle 12cr1 is install in my local machine.

lsnrctl status gets:

and

alter session set container = pdborcl

also works.

Answer 1

using / AS SYSDBA will work as it did in previous releases at the container database level (CDB). but It's NOT able to connect to the pluggable database (PDB) without password by sqlplus.

The simplest way to achieve this is to continue to connect using "/ as SYSDBA", but to set the specific container in your script using the ALTER SESSION SET CONTAINER command.

sqlplus / as sysdba <<EOF

ALTER SESSION SET CONTAINER = pdb1;

-- Perform actions as before...
SHOW CON_NAME;

EXIT;
EOF

you also can refer this article for more information Multitenant : Running Scripts Against Container Databases (CDBs) and Pluggable Databases (PDBs) in Oracle Database 12c Release 1 (12.1)

Answer 2

I am using

sqlplus sys@pdborcl as sysdba

and entering the password.

show con_name;

yields the value

CON_NAME
------------------------------
PDBORCL

Answer 3

Try

sqlplus /@localhost.localdomain/orcl.cn.oracle.com as sysdba

if that's the service you want to log on to (not sure if I understand your question entirely).
