Unable to resolve service name

I am vishnu prasath.i am a reader of oracle magazine.
I need a help from you.I have installed Oracle 9i
in my machine.when i was installed it asked me to enter
SID.i entered as specified in the example ie test.acme.com where as Globaldatabase name=test.when i tried to work with SQLPlus it is showing error "TNS protocol error".how to change tnsnames.ora file.
i saved tnsnames.ora as tnsnamesold.ora and i tried
to enter the following
tnsnamesold.ora:
Test.acme.com =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(Host=localhost)(PORT = 1521))
(CONNECT_DATA =
(SID_NAME =Test.acme.com)
even after changing it is showing the same error.
Please send me correct tnsnames.ora according to the
above information.
i hope you a positive reply.

If the client ( sqlplus ) and the database ( 9i ) are
or the same machine you don'e need to give the service name. live if black, it will use internal connection instead of TCP connection (1521).

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 ??

ORA-12154 TNS could not resolve service name error

Hi
I'm having trouble connecting to database throug sql*plus.I'm able to connect through TOAD but getting 'ORA-12154 TNS could not resolve service name error' when trying to login through sql*plus using same credentials .
I tried running sqlplus through command prompt,but when i enter the user-name i'm getting ORA-12203:TNS:unable to connect to destination.
Can someone help me with this error.
Thanks.

It would probably give you an idea where to start looking. You need to make sure that you have the correct .ora files needed for establishing connections. I don't know if your service desk just does the installation but no setup or if they also do the setup configuration. You can also try doing the setup on your own to check. You can use net easy config.

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...

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 =

Would it be possible to get rid of the connect error?
Where is the config error?
Any ideas are highly appreciated!

Execute the sqlplus executable with absolute path. Also verify if you have declared the TNS_ADMIN environment variable. It should not be set, it defaults to your ORACLE_HOME/network/admin path. You could also fix it to explicitly point to the path where your tnsnames.ora file resides.

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.

ORA-12154 Could not to resolve service name

I need some help. We have installed Oracle 8.1.6 for Windows NT on my PC one year ago. I also have Forms 5.0 on my PC that had connection service to Oracle database on Unix mashine. Now we don't have this database on Unix mashine so I desided to create a new small database on my PC in order to run some existing Forms. Using Oracle Net8 easy to config I created new service datamart/datamart@orc0 (It was possible only using IPC(local process) not TCP/IP). Now I can access my database using SQL*PLUS but I cannot to connect to this database using Forms. I have error message:

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.

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.

Oracle 9i "TNS:could not resolve service name" on 64-bit OS

I have a 32-bit .NET 3.0 application that can run on 64-bit OS using WOW64. When I connect to the database on 32-bit OS with 9i (9.2.0.1) client, everything works fine. However, if I install the same client on 64-bit OS (assuming that it would run using WOW64) and run the application, I get "TNS:could not resolve service name" error.
To make sure that it's not something with configuration, I've installed both clients in the same directory on 32-bit OS and 64-bit OS, and copied the same tnsnames.ora and sqlnet.ora files. I can also connect to the database without a problem on 64-bit OS using SQL Plus. The error only occurs when connection is made via the application, which uses .NET oracle client. The only main difference is that on 64-bit OS, 64-bit version of .NET 3.0 is installed.
Does anyone have an idea why I am getting this error?
