ORA-12514

Either configure the tnsnames.ora file with the proper information or try the ezconnect method.

I've never tried this with exp but it appears to work for sqlplus:

http://asktom.oracle.com/pls/asktom/f?p=100:11:0::NO::P11_QUESTION_ID:45033135081903

try (replace the information with your user/password and dbserver info:

exp 'scott/tiger@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=152
1)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ora9ir2.kyte.com)))'

Sorry for the delayed response...
I have just the oracle client installed on my local PC (When I installed it, I didnt even have the tnsnames.ora file I copied that in to the ADMIN folder). I got the tnsnames.ora file from my teammate. He is able to login with the alias with TNS option. But I am not able to, I have to use the "DIRECT" option, IP address of the database and its SID and port to login. If I use the TNS option its throwing the error:

ORA-12154 -- TNS: could not resolve the connect identifier specified.
I am using TOAD tool

Thanks@

I've never used Toad so I'm not sure if it has it's own Oracle piece or uses an installed Oracle client.

Anyway the ora-12154 means there is either a configuration issue with your tnsnames.ora file or you aren't using a valid entry in that file.

since you copied it from a co-worker, are they on the same network you are on and are they connecting to the same databases you are on?

If you have sqlplus installed, I would prefer to troubleshoot this error using sqlplus and not Toad.

I know posted on the wrong thread and got confused, I dont know how to delete it from the other one...

I am not talking about the exp utility. I want to clarify about just this error.
Whenever I try to login I get this error. I want to fix this first.

Yes my co-worker is on the same network and connecting to the same database.

I tried using SQL*PLUS, I still get the same error.

>> dont know how to delete it from the other one...

I've taken care of deleting the posts in that thread.

>>I tried using SQL*PLUS, I still get the same error.

Do you have more than one Oracle client/product installed on the machine?

Are you running sqlplus from UNIX or Windows?

Oracle Client installed on my local PC windows, the sever is in UNIX box.
I am running sqlplus in my local windows machine.
In unix it works fine..

Thanks

If the tnsnames.ora file from the Windows machine doesn't contain any sensitive server names or database names, can you post it?

If the names are sensitive, can you dummy them up and post the dummied file?

PPROD =
  (DESCRIPTION =
    (ADDRESS =
      (PROTOCOL = TCP)
      (HOST = 192.42.185.211)
      (PORT = 1521)
    )
    (CONNECT_DATA =
      (SID = fprdd1)

    )
  )

From a cmd prompt post the results of:

ping 192.42.185.211
and
tnsping pprod

the ping is fine..
But tnsping gave me the following error:

Used parameter files:
C:\oracle\product\10.2.0\client_3\network\admin\sqlnet.ora


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 192.42.185.211) (PORT = 1521)) (CONNECT_DATA = (SID = fprdd1)))
OK (20 msec)

My SQLNET.ORA file contains:

SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
#NAMES.DIRECTORY_PATH= (LDAP, TNSNAMES, EZCONNECT)

Thanks@

>>But tnsping gave me the following error:

What error? It ran fine.  See "OK (20 msec)"

now from a command prompt:
sqlplus username/password@PPROD

I gave this: sqlplus username/password@PPROD (Of Course I agve my username and password)
and got:

SQL*Plus: Release 10.2.0.1.0 - Production on Mon Feb 28 12:03:18 2011

ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified


Enter user-name:

log into the server: 192.42.185.211 and from a command prompt post the results of: lsnrctl status

from a command prompt:
set TNS_ADMIN=C:\oracle\product\10.2.0\client_3\network\admin

then try: sqlplus username/password@PPROD
and/or
C:\oracle\product\10.2.0\client_3\bin\sqlplus username/password@PPROD

Perfect! I just uninstalled the other versions and it worked fine..
Thanks a lot slightwv!
