ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect

Hi Friends,
I have created 10g database for catalog.
I kept the tns entry in some other server. Tnsping is working fine.. I can see the result.

Please help me..
Thanks in advance.

Try on the server where it doesn't work:
sqlplus ismdba/xxxxx@"(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = torora60)(PORT = 1522))) (CONNECT_DATA = (SERVICE_NAME = rman09na)))"
or
tnsping "(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = torora60)(PORT = 1522))) (CONNECT_DATA = (SERVICE_NAME = rman09na)))"
(note the double quotes)
If that works then your tnsnames.ora is incorrect on that server.

Hi...Please help...Getting ORA 12154 TNS Listener could not resolve...

Hi,
I have just loaded Oracle 10g Rel 2 in Win 2003 Enterprise Edition.
But when I try to connect to sqlplus, I am getting ORA -12154 : TNS: Listener could not resolve the connect identified specified.
I have registered the database, the listener and tnsnames have been set correctly.
I have also set the Oracle Home environment variable.
Still getting the error.
Any help will be highly appreciated.
Thanks,

I agree
ORA-12145: (does not exist in the standard manuals)
ORA-12154: TNS:could not resolve the connect identifier specified
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
ORA-12541: TNS:no listener
It is pretty easy to fat-finger these 4 message numbers. As a result, when a person has the actual and complete error message and an error number for a different message, it is usually not a bad idea to use the actual message. (Based on transposing only 3 digits compared to typing over 50 characters correctly.)
In this case the OP has really bollixed things: Subject implies a true 12154, text in the thread is an actual 12514 but mentions 12154.
As a result, there are several potentially correct answers, depending on the interpretation of the question.
- sb92075 gave the correct answer based on the number
- I gave the correct answer based on the message in the thread
- Anurag and Ed gave the correct answer based on 'the question is not formed correctly'

ORA-12514: TNS:listener could not resolve SERVICE_NAME given in conne

I am running Oracle 8.1.7.1.4 on Windows 2000. After I created a database TEST using a script created by my previous colleague, I got the following error:
sqlplus SYSTEM/PASSWORD@TEST
ERROR:
ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect descriptor
Enter user-name:
But if I enter system as username and the password, I could connect to sqlplus without any problem.
I checked the OracleServiceTest is running as a Service, and here is what in my tnsnames.ora.

The following is what in my sqlnet.ora file.

Here are a few important lines in my init.ora file.

instance_name = TEST

I tried to use sqlplus system/[email protected], but got the same error.
Any help would be greatly appreciated.
Thanks,

Hi Werner:
Thank you very much for your suggestions. Yeah, I have
a db_domain = UNHQ.UN.ORG in my init.ora file. I tried
to append it manually into the service_names in my
init.ora file and made corresponding changes to
tnsnames.ora file. Now I could access to TEST database
without any problem.
I have another question. How can I prevent the
db_domain from appending to SERVICE_NAMES by default?
By set it to db_domain="" or just don't have it in my
init.ora file? I don't want to have the domain name
appearing in my SERVICE_NAMES.
Thanks,
Jane

ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect des

Hello all,
I installed a 10g client on a windows PC, which already had 8i installed.
SQLPlus login works for databases in both environments, but now a 8i database cannot be connected from Visual Studio.
ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect descriptor
I immediately checked both tnsnames.ora, but I don't see anything wrong.
sqlnet.ora has:
SQLNET.AUTHENTIFICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES)
Has anybody encountered this issue?
I'm thinking of de-installing 10g now...
Thanks in advance.

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action:
- Wait a moment and try to connect a second time.
- Check which services are currently known by the listener by executing: lsnrctl services <listener name>
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.
- Check for an event in the listener.log file.
Pay special attention to these possible reasons:
- Check which services .......
- Check that the SERVICE_NAME parameter ...........
There's a mismatch between service_name is tnsnames.ora and service_name known by the actual listener.

ORA-12514 TNS:Listener could not resolve SERVICE_NAME given in connect desc

Hi
It's my first post and the first time I use an Oracle product. I begin with Oracle 10g. When I want to connect to an oracle database through vs2003 or vs2005, three things should be provided. 1.Server name(I don't know it?!) 2.Username(I don't know it?) 3.Password(I don't know it?)
I set password for SYSTEM, SYS and their passwords are the same. I don't know whether SYSTEM is my user name or not?
I enter localhost for server name and the above error occures.
Thank you
Seyyed Reza Qomi Behbehani

do not connect oracle with system,sys or whatever username with sysdba or sysoper role.create new normal user to connect oracle machine.server name is oracle service name(SID).don't connect with localhost server except you set your service name to localhost..servername may be orcl or ora10g

TNS-12154 Could Not Resolve Service Name

I'm getting this error when I try to access the database from a Windows.NET program. What's even more frustrating is that I had it working before. I must have inadvertently changed something in the Oracle or network settings
I'm baffled by this error because TNSPING and SQLPlus to the same service are being accessed without a hitch.
Anyone have an idea where I might find the problem or how to test for it?
Thanks in advance!

Does .net still use ODBC? If so go into your control panel, Administrators tools, ODBC Administration and check out what you set up.
Just a shot in the dark but who knows

TNS Could not resolve SID given in Connect Descriptor

Hi All
Having a problem with a dataexport command in a calc script.
Am using the command as follows:
DataExport "DSN" "ProdServer" "Table Name" "username" "password";
The similar command works fine in UAT.
When I run the script I get this error:
OK/INFO - 1021013 - ODBC Layer Error: [08001] ==> [[DataDirect][ODBC Oracle Wire Protocol driver][Oracle]TNS-12505: TNS:listener could not resolve SID given in connect descriptor].
OK/INFO - 1021014 - ODBC Layer Error: Native Error code [4294967295] .
ERROR - 1021001 - Failed to Establish Connection With SQL Database Server. See log for more information.
The ODBC connection is setup the same as in UAT with the correct port number.
This is also shown:
ODBC Layer Error: [S1000] ==> [[DataDirect][ODBC Oracle Wire Protocol driver]Cannot open TNS Names file.]
Could it require the restart of the TNS listener?

Listener could not resolve SID given in connect descriptor

Hello,
I have three servers : two with oracle 9.2.0.1 databases and one with application. I have a load balancer, with a virtual IP, that manage the connections to the databases. The two databases are the same. My application connects to the database via the virtual IP of the load balancer. When my application connects, I have the following error in the listener.log :
13-JUL-2006 11:53:48 * (CONNECT_DATA=(SID=SSOSESS)(CID=(PROGRAM=NSora20.so)(HOST=ssops1)(USER=smuser))) * (ADDRESS=(PROTOCOL=tcp)(HOST=<my_ip>)(PORT=8409)) * establish * SSOSESS * 12505
TNS-12505: TNS:listener could not resolve SID given in connect descriptor
But, when I do an sqlplus request from the server of the application to the virtual IP of the databases, it works fine :
13-JUL-2006 11:54:57 * (CONNECT_DATA=(SERVICE_NAME=SSOSESS)(CID=(PROGRAM=)(HOST=ssops1)(USER=smuser))) * (ADDRESS=(PROTOCOL=tcp)(HOST=<my_ip>)(PORT=8411)) * establish * SSOSESS * 0
I have you got an idea of the cause of the error ?
Thanks...
Delphine

The tnsnames.ora that my application uses iscorrect,
I think :
(SERVICE_NAME = SSOSESS)This does not say "SID=..." which was used in the
failed connect attempt (per listener.log)?
>
Do you have several tnsnames.ora files, maybe?
(search the drive/file systems)
Maybe some app specific config?I don't have several tnsnames.ora. In my application, I have to setup the host name, the user, the password, the port and the sid.
>
Hm, I was sure sid/service_name from tnsnames.ora and
listener services had to match but now I'm not...
Dont have a setup to test in right now.
What does lsnrctl serv output?I dit the lsnrctl command on my database server, and I had the following result :

Ora 12154: TNS could not resolve connect identifier specified

Hi,
I have Oracle 11g (Release 1_32bit) Client on my C:\ drive which connect to a Remote 11g (11.1.0.7.0 - 64bit) server.
I have installed 10g DB Server(10.2.0.1.0) and Oracle 10g Forms(Forms [32 Bit] Version 10.1.2.0.2 ) on my D:\ drive.
When I try to connect to Oracle 10g DB from Forms using "Connect" button, I get following error:

Ora-12541 ORA-12154: TNS:could not resolve the connect identifier specified

I am having trouble obtaining an ODBC connection from a client XE to a server XE. ora-12541 ORA-12154: TNS:could not resolve the connect identifier specified
I am new to Oracle.
I have oracle client XE running on my XP pro box.
I have oracle server XE running on an XP pro box on the LAN.
I am trying to connect to the oracle database using ODBC from my client box.
I can logon to the oracle server box through HTTP.
I can logon to the oracle server box by using a connection string in "Command Line SQL" from my client computer. I can then run queries on my client computer. (select * from global_name)
I cannot setup an ODBC connection in windows which will connect to the oracle server box from my client box. (I have no trouble connecting to MSSQL databases).
I can ping my server by hostname or ip address. Both ok.
I can run tnsping XE on the server box and it works. I believe this tells me my server listener is working.
I cannot run tnsping on my client box as it is not included in the download for Client XE.
Windows firewall is turned off on both machines.
I have been reading all over the web for and all attempts fail. Most all help says use Oracle Net Manager or some such tool. They then say go to start\programs\oracle….etc. There is no type program included on the server or the client software. I would like to know here I can download it.
XEClint\Bin is the firs entry in my PATH. The tnsnames.ora, sqlnet.ora, and listner.ora files are there. I have been to http://www.oracle.com/technology/software/products/database/xe/files/install.102/b25143/toc.htm several times. My tnsnames.ora are identical to the ones in the example except for the host =.
I have 3 tnsnames.ora files on my computer:
Directory of c:\
04/03/2008 11:43 AM 635 tnsnames.ORA
Directory of c:\Documents and Settings\All Users\Application Data\Microsoft\Net
work
04/03/2008 11:43 AM 635 tnsnames.ORA
1 File(s) 635 bytes
Directory of c:\XEClient\bin
04/03/2008 11:43 AM 635 tnsnames.ORA
1 File(s) 635 bytes
They are all identical.
When I ran lsnrctl status on the server the results were the same as found in other articles in the web site. Default service XE
I have the Oracle in XE Client driver in my windows ODBC driver list of the client box. And other Oracle drivers.
It appears I am lost.
Any help would be appreciated.

I cannot setup an ODBC connection in windows which will connect to the oracle server
box from my client box. (I have no trouble connecting to MSSQL databases).How you tryed to do that?
On which step you have problems?
