SQL> select con_id, name from v$containers;

    CON_ID NAME
---------- ------------------------------
         1 CDB$ROOT
         2 PDB$SEED
         3 PDB1

=> I have only one pluggable database PDB1


1) create user(local user) in pluggable database

SQL> show con_id

CON_ID
------------------------------
1
SQL> show user
USER is "SYS"

SQL>  alter pluggable database pdb1 open;

Pluggable database altered.


SQL> alter session set container=pdb1;

Session altered.

SQL> show con_id

CON_ID
------------------------------
3
SQL> show user
USER is "SYS"


SQL> create user local_scott
  2  identified by tiger
  3  CONTAINER=CURRENT;

User created.

SQL> grant connect,resource to local_scott;

Grant succeeded.

2) edit listener file listener.ora (add plugglabe database entry)

/u01/app/oracle/product/12.1.0.2/db_1/network/admin   ---file location

[oracle@cdb1 admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/12.1.0.2/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = cdb1)
      (ORACLE_HOME = /u01/app/oracle/product/12.1.0.2/db_1)
      (SID_NAME = cdb1)
    )
  )
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /u01/app/oracle/product/12.1.0.2/db_1)
      (SID_NAME = orcl)
    )
  )
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PDB1)
      (ORACLE_HOME = /u01/app/oracle/product/12.1.0.2/db_1)
    )
)
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = cdb1.example.com)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/oracle

3)Edit tnsfile  file tnsnames.ora  (add pluggable database entry)

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.1.0.2/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

CDB1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = cdb1.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cdb1)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = cdb1.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )
PDB1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = cdb1.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = PDB1)
    )
  )

4) check test conectivity

[oracle@cdb1 admin]$ tnsping pdb1

5) connect pluggable database using local user (local_scott)

[oracle@cdb1 admin]$ sqlplus local_scott/tiger@pdb1
