How to create the database on link using PR47 as the local machine?

When I ran this script I get the following error

SQL> select * from xxtbpc.xxtbpr_organizations@tprd;
select * from xxtbpc.xxtbpr_organizations@tprd
                                          *
ERROR at line 1:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor

Yes I can  ping tprd.

I have two tnsnames on client_2 and db_1 please check it there is anything wrong on this.

This  one is for db_1

# tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora

PR47 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.85.24)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = PR47)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

 xxtbpr_stations_pr47=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST =172.16.85.24)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME =xxtbpr_stations_pr47)
    )

  )
TPRD=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST =172.16.85.24)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME =TPRD.REGRESS.RDBMS.DEV.US.ORACLE.COM)
    )

This one is for client_2

  (DESCRIPTION =

    )
    (CONNECT_DATA =
      (SERVICE_NAME = PR47)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =

    )
    (CONNECT_DATA =
      (SERVICE_NAME =xxtbpr_stations_pr47)
    )

  )

TPRD=

    )

  )

This are the tasks I was asked to do:

I created this database link but still  gives me the same error

create database link xxtbpr_stations_pr47 connect to pr identified by pr using 'PR47'

create database link TPRD.REGRESS.RDBMS.DEV.US.ORACLE.COM connect to XXTBPC identified by XXTBPC using 'TPRD'
