TNS couldpt resolve service name

Hi all,
I installed Orale8i on win 2000 server.Later i deinstalled and installed Oracle 9.0.2 on Win 2000 server.I am successfully logging into Oracle 9i through
SQL Plus.If i try to log in Oracle thru TOAD getting following error
Building Oracle HOMES List
HOME Name OraHome81 added to list.
HOME Name OraHome91 added to list.
Found multiple homes, searching each HOMEx for valid PATH
searching in SOFTWARE\ORACLE\HOME0
Oracle_Home found in SOFTWARE\ORACLE\HOME0 IS in system path!
searching in SOFTWARE\ORACLE\HOME1
oci.dll found

Do you have a backup of your registry? Mucking around with registry entries around Oracle Home's is notoriously difficult because lots of keys reference each other. It's certainly possible to fix everything, but it isn't a simple process.

ORA-12154 - TNS couldnt resolve service name

I have created the following db link :
CREATE DATABASE LINK RAN.WORLD
CONNECT TO <>
IDENTIFIED BY <>
USING 'DCCCSN1'
select * from [email protected]
This gives ORA-12154 - TNS couldnt resolve service name
Can someoen advice regarding this please ? I can use the user id and password used to create the db link to connect to the database .Also from command prompt TNSPING DCCCSN1 -also works .So there should be nothing wrong with the TNS entries .Thanks .

Just want to emphasize on the same point Legatti mentioned.
The tns entry you mentioned must exist in the tnsnames.ora of the server where the your database (where the dblink has been created) resides.
Lot of times people think that the tns entry is required on the machine you running the command from, which is wrong.
Thanks,
Ankit.

Tns could resolve service name

I have oracle 9i client installed in my machine
I have installed oracle 9i DS - complete
I have copied my tnsnames.ora from oracle_home of my client to DS - Home - Network-Admin folder.
I able to test my connection in net manager but when I connect thru forms builder it says ora-12154 tns could not resolve service name
I have also manually created the tnsnames.ora thru net8 manager but still I am getting the same problem
Please can anyone help on this

Shasi,
Frank really is right. This is a network configuration problem, particularly the tnsnames.ora (and possibly but unlikely the sqlnet.ora).
Try connecting from the sql plus in the Oracle Home where Forms & Reports are. You'll get the same error message. You can try to copy the same files over from the database if you're able to connect from that SQL Plus using username/password@connectstring successfully,
This problem is one we see all the time and is always (maybe a Powerball lottery's odd change it's something else) network configuration files. Make sure they are in the right Oracle Home (Forms & Reports) and that the ones you have work somewhere else.

Tns coulnot resolve service name problem on serverside alone

Hi all,
i have a problem in serverside tnsnames.ora when i try to connect from client to server i am able to connect whereas if i am trying to open the sqlplus with the same username on server i couldn't connect i receive this error
Sathish aravamuthan

I just resolved this same problem, so maybe this will help you. From the server try the following:
Do you have $TNS_ADMIN defined in your environment variables? echo $TNS_ADMIN
cd $TNS_ADMIN
Are sqlnet.ora and tnsnames.ora located here?
When you type "tnsping test.world" does tnsping show that it's using the same sqlnet.ora and tnsnames.ora files that you're viewing? {test.world is a real database for me, so choose an appropriate substitute}
Does the tnsping show OK (0 msec)?
Did you FTP these files from another server? You MUST transfer them in ASCII (not the Linux FTP default of binary). The binary FTP seems to cause the OK (0 msec) problem.
Does your sqlnet.ora have the following line?
SQLNET.AUTHENTICATION_SERVICES= (NTS)
Make sure to delete that if it does.

TNS:cannont resolve service name

i can't understand why this message comes over when i work in form designer in spite of i write the right name of the database

i think you must have not added the database string in tnsnames.ora. please check that if it is added in the file. then try running.

ORA - 12154 TNS:couldnot resolve service name

hi all
Thank you for all your support .
Now i am facing a problem . I am using oracle 9i and TOAD 7.3 . we have 4 machines .We can connect to Oracle server from 3 machines through toad .
But from my machine its showing the above error .But i can connect to the server through RUN (sqlplus username/password@databasename) .
When i uninstall the TOAD and if i connect it's getting connected. If i shutdown the system and try to connect through TOAD , it will display the error again .
I copied the sql.net and tnsnames.ora file from other machines which are connecting properly ,then also its not working .
If anybody knows about this please help me
thanks & regards

Oracle networking client gets an alias via @databasename.
Networking looks up that alias in TNSNAMES.ora - if there is no '.' at the end of the alias it checks the SQLNET.ora for the possibility of a default domain to append.
It selects the alias from TNSNAMES.ora ...
- TNS_ADMIN points elsewhere = ORA-12154
- wrong tnsnames.ora when multiples exist (common) = ORA-12154
- no tnsnames.ora = ORA-12154
- no alias = ORA-12154

TNS: could not resolve service name

ERROR: ORA-12154: TNS: could not resolve service name
does any1 know what this means...and how to overcome this problem
username : scott
passwd: tiger
host string: myora
i have personal oracle8i in d:\oracle
and d2k in d:\d2k
it connects with the SQLPlus
however with d2k when i try to connect it gives the above error
message.
does any 1 know a solution to the problem...

Hello,
First of all, If you are using PO8i and D2k as a front end
on single machine,no need of specifying Connect String. You can
connect using scott,tiger. If still it is giving problem,try
this one.
Open TNSNAMES.ORA file from folder NET80/Admin in your PC
using NOTEPAD. Look there entry for myora. If it is there,Check
SID,IPAddress or remove word "World" from there. See E.g
ora816 = -- Your connect string
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Host = 10.0.0.3) -- IP address
(Port = 1521)
(CONNECT_DATA = (SID = ora816) -- Database SID
Hope it will work...

IFS 9 : TNS:could not resolve service name

Hello,
I have this message when Trying to connect in Java to IFS 1.2 :
oracle.ifs.common.IfsException: IFS-21008: Unable to connect to
iFS service
java.sql.SQLException: ORA-12154: TNS:could not resolve service
name
I have been developing with IFS 1.16 for a while but now I have
to upgrading to IFS 9 (1.2). To set up my development
environment I did the same thing that I did for the version 1.1.6
1-     Copying all Jar from D:\oracle\ora90\9ifs\lib and I had
them to my classpath
2-     Copying the folders under D:\oracle\ora90\9ifs\settings
to have access to the IfsDefault.properties. file.
3-     I got the new JDBC driver and Oracle Client 9 on my
developer station.
IfsDefault.properties is pointing to the right TSN. When I test
my TSN (orcl) with the SQL+ it works just fine. I tried to use a
Invalid Ifs Service Name instead of IfsDefault too see if I got
a different error message and no, I got the same error. It looks
like the environment doesn’t find the IfsDefault.properties
file ?
Any Idea of it could be ?
There is the code that I use to connect :
LibraryService service = new LibraryService();
CleartextCredential cred = new CleartextCredential
(username, password);
ConnectOptions options = new ConnectOptions();
options.setLocale(Locale.getDefault());
options.setServiceName(repository);
options.setServicePassword(repositoryPass);
_ifsSession = service.connect(cred, options);
// Doit mettre explicitement le Admin flag dans la
Session
DirectoryUser user = _ifsSession.getDirectoryUser();
_ifsSession.setAdministrationMode(user.isAdminEnabled
_logger.info("user " + user +" is now connected to
Ifs " + repository + ", " + _loggedUserCounter + " connected.");
Thank you

Looks like your TNSnames is not properly configured .. Did you
try to do a sqlplus from the command prompt to see if you can
connect to SQLPlus ??

Fundamental Problem: ORA-12154: TNS:could not resolve service name

Hello,
I am faced with a fundamental problem:
ORA-12154: TNS:could not resolve service name
I can say with a high level of confidence that the TNSNAMES.ora configuration file is not the problem. My peer is using the exact same file with no issues. I am using the TOAD database utility to connect to the db host. Also, I have ORACLE_HOME defined and the file is located in /network/ADMIN.
Any ideas?

Hello,
Make sure your toad looking into right tnsnames.ora; also try this from command line after adding following entry to your tnsnames.ora.
sqlplus username/password@ECDEV
ECDEV =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS =
        (PROTOCOL = TCP)
        (HOST = rscdd01) --> you can try ipaddress of your server name as well
        (PORT = 1521)
    (SDU = 8192)
    (CONNECT_DATA =
      (SERVICE_NAME =ECDEV)

MSDAORA,IIS,ORA-12154: TNS:could not resolve service name

Hi All,
I have a Web Service that coded in VS2008, using ORACLE DB(9i).
At a time the application working fine and I can access and do everything with database.
Some other time database server is down for scheduled maintenance. If I try to run the application at this point of time it will raise err "ORA-12154: TNS:could not resolve service name".
When i reset iis it start to work fine for a while.Then same problem occurs again.
My connection string is connectionString="provider=MSDAORA.1;data source=***;user id=***;password=***;"
is there any solution?
i tried that;
If theire is multiple copies of OCIW32.dll you have to make sure that there is only one copy of OCIW32.dll which should be in /Bin folder of the oracle home folder.
Add the IUSR_machine name account and the IWAM_machine name account to the Oracle home folder. Give both accounts full control.
Create empty file tnsnames.ora in same directory as aspnet_wp.exe,

Hi,
The issue doesnt make much sense on the surface at least. 12154 means the client couldnt figure out what you were referring to with your Data Source= entry. If the database was taken down, I'd expect an "oracle not available" or some other sort of error, as the client should have still be able to resolve the entry at least, even if the database wasnt up at the time.
What do you mean by "When i reset iis it start to work fine for a while.Then same problem occurs again."? The same problem meaning you get 12154 when you take the database down? Or you get 12154 without a db restart?
Are you using TNSNames.ora for client naming resolution, or something else (ldap, for example)?

ORA -ERR :Tns could not resolve service name

Hi,
I am tring to get into sql plus. As the oracle is pre installed and as donot know the system password, I am tring to login as Scott/tiger and host string as 'ORCL'.
I am getting the following error.
ORA-12154 :
Tns could not resolve service name
Is there any way to find the Host string name through any of the installation files.
Please suggest.
Badrinath

Hi,
Open the tns file ( available at oracle_home/network/admin/tnsnames.ora). I do not know what your oracle_home name is. Usually it is oracle/ora81/ under c: or D: or where ever you installed Oracle. Go thru the file. You will find the service name. Use that while logging. If you want to login to ORCL, it has to be there in tns files name otherwise Oracle cvan not resolve the name.
Good luck

ORA-12154: TNS:Could not resolve service name. (WIS 10901).

HI Gurus, we have the following scenario...
Weu2019ve installed Busines Objects EDGE 3.1 SP3.
The server of this installation is MS Windows Server 2003 Enterprise Edition SP2, Intel ® Xeon Enterprise TM CPU 2.80 GHz 6.5 RAM.
In the Server we have SAP R/3 Installed over a DB Oracle 9i Enterprise Edition Release 9.2.8.0.
We installed all BO bundle with successful and we can use the Designer Tool for create universe. In the creation of the universe, we created a connection to the database of the SAP R/3 System and the test runs well, we save and export the universe to CMS. Then, we used that universe in the WebI tool of the suite installed in the server, and it runs well (we call the universe, selected fields of the table, and after run the query, it gives us registers of the DB).
After all this, we open the InfoView and used the WebI and execute the same universe and the same steps. And when we execute the query the following error occurs .
A database error occured. The database error text is: ORA-12154: TNS:Could not resolve service name. (WIS 10901)
The connection to DB is through Designer and we use ODBC Oracle to create the Universe with the Client type and we used super user system, validated previously OK.
Any suggestion for this error?.
Thanks.
Betto.

Make sure there are no syntax errors in the TNSNAMES.ORA file, look for unmatched parentheses. Also check the SQLNET.ORA file.
Is the environment is clustered, if so then make sure you have the ODBC connection in all the servers.

Hello,
Make sure that the service which you have specified in jdbc for making connection with oracle, exists in TNSNAMES.ORA file. You will find this file at different locations in 8i and above. So, better search for it. And add you service name in it. Example services is given in this file itself. So, take help from them.
