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.
mexn01:$ tnsping rman09na
TNS Ping Utility for HPUX: Version 9.2.0.5.0 - Production on 28-APR-2008 19:29:07
Copyright (c) 1997 Oracle Corporation. All rights reserved.
Used parameter files:

Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = torora60)(PORT = 1522))) (CONNECT_DATA = (SERVICE_NAME = rman09na)))
OK (0 msec)
When I am trying to connect to the database I am getting following error..
mexn01:$ sqlplus ismdba/xxxxx@rman09na

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

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

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

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.

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

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 :

plz help me to come out to this problem.
Thanks & Regards,

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.

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'

you should properly configure the SQL*NET files - sqlnet.ora and

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:

The ODBC connection is setup the same as in UAT with the correct port number.
This is also shown:

Could it require the restart of the TNS listener?

My guess is that the database service "HCM" is not up and running but not sure how to make up and running. Even I could not find it listed in the linux services list.
Note: Able to login sqlplus using "sqlplus sys/sys as sysdba" but failing to access database table as "select * from PSRECDEFN;"
thanks

Hi Nicolas,
I have no luck and the error still persists.
I have set the "export ORACLE_SID=HCM" from root user and oracle user too.
I guess, I have already loaded database when I ran the "cd /opt/oracle/psft/vm
./oraclevm-template.sh"
The outcome of the above script as similar as below:

Problem: ORA-12514, TNS:listener does not currently know of service request

When I enter a command for an Oracle 10g Express installation I am getting the following error:

Hmm, whats wrong?

Hi,
no, you got it wrong:
Oracle uses network services which are a logical representation of the database to resolve network requests.
in your ntsnames.ora file you have the following:
network_alias = my_alias -- here you can write anything you just need to resolve it correctly
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(host=hostname or IP)
(port=listener adapter port)
) -- this a complete socket information of the listener adapter!!
(CONNECT_DATA=
(SERVICE=your_service) -- this is what you tell the listener about the service you want to connect to. It is defined in the instance with the paramter service_names
In general it is network aliasses which are resolved with connect descriptor in the tnsnames.ora.
A connect decriptor consists of the address part + the connect_data part.
The address part is used to reach the listener.
The connect_data part is the information you hand over to the listener.
So the listener must know the service name.
The listener can either know this from the instance itself. When an Oracle instance is started it tries to registrer itself with a listener which listens on port 1521 for the protocol TCP.
The instance tell this listener two paramater values: INSTANCE_NAME and SERVICE_NAMES. Then the listener knows the instance and which services are defined. It is just a reprentation of the database to the listener.
If the listerner knows the service requested with a connect, it can establish a connection to a service handler. This could be a dedicated server process or a dispatcher.
Another mehtod to let the listener know the service requested is so called static regustration of the instance. This is made with an SID LIST in the listener.ora file.
Then the listener knows SID for the instance plus ORACLE_HOME and can find the executable to start a server process for a connect request.
Hope it helps a little-.
=;-)
If you have further questions pls do not hesitate to ask. O.K.?
