Hi All,

I instaledl Oracle Database 11g in my PC and try to login to it. I am able to log to it via SQLDeveloper but I can not login via SQLPLUS and I got ORA-12154. Here is my TNSname.ora and SQLplus.ora

# sqlnet.ora Network Configuration File: C:\app\mhakimjavadi\product\11.2.0\dbhome_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.

TRACE_LEVEL_CLIENT = OFF

NAMES.DIRECTORY_PATH= (TNSNAMES)

AUTOMATIC_IPC = OFF

# tnsnames.ora Network Configuration File: C:\app\mhakimjavadi\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)

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

DEV =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MARK-HAK.loyalist.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DEV)
)
)

Please advise.

Thank you in advance.

ORA-12154: TNS:could not resolve the connect identifier specified
 *Cause:  A connection to a database or other service was requested using
 a connect identifier, and the connect identifier specified could not
 be resolved into a connect descriptor using one of the naming methods
 configured. For example, if the type of connect identifier used was a
 net service name then the net service name could not be found in a
 naming method repository, or the repository could not be
 located or reached.
 *Action:
   - If you are using local naming (TNSNAMES.ORA file):
      - Make sure that "TNSNAMES" is listed as one of the values of the
        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
        (SQLNET.ORA)
      - Verify that a TNSNAMES.ORA file exists and is in the proper
        directory and is accessible.
      - Check that the net service name used as the connect identifier
        exists in the TNSNAMES.ORA file.
      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
        file.  Look for unmatched parentheses or stray characters. Errors
        in a TNSNAMES.ORA file may make it unusable.
   - If you are using directory naming:
      - Verify that "LDAP" is listed as one of the values of the
        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
        (SQLNET.ORA).
      - Verify that the LDAP directory server is up and that it is
        accessible.
      - Verify that the net service name or database name used as the
        connect identifier is configured in the directory.
      - Verify that the default context being used is correct by
        specifying a fully qualified net service name or a full LDAP DN
        as the connect identifier
   - If you are using easy connect naming:
      - Verify that "EZCONNECT" is listed as one of the values of the
        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
        (SQLNET.ORA).
      - Make sure the host, port and service name specified
        are correct.
      - Try enclosing the connect identifier in quote marks.

   See the Oracle Net Services Administrators Guide or the Oracle
   operating system specific guide for more information on naming.

>I am able to log to it via SQLDeveloper but I can not login via SQLPLUS and I got ORA-12154.
SQL Developer default to use JDBC thin to connect to the DB; which does NOT use tnsnames.ora

ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 NEVER involves the listener, the database itself or anything on the DB Server.
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
The lookup operation fails because the name provided can NOT be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.

I don't know what you do.
I don't know what you see.
It is really, Really, REALLY difficult to fix a problem that can not be seen.
use COPY & PASTE so we can see what you do & how Oracle responds.

above is from original post in this thread & below is from your last post.
> Now I tried to connect to DB via sqlPlus or MS ODBC and I got Ora-12541.

Did the error really change from ORA-12154 to ORA-12541 or do you have a problem using COPY & PASTE?
