TNS error on isqlplus

Hello,
I can connect to the oracle 9i server with sqlplus but
when I try to connect with isqlplus in my webbrowser I get error "ORA-12154: TNS:could not resolve service name",
In the connector-id field I put the same as I use for the hoststring in sqlplus.
Thanks in advance

Hallo,
I get the same error message number ("ORA-12154: TNS: could not resolve service name") when trying to connect via normal sqlplus (SQL*Plus: Release 8.1.7.0.0) from a Linux client (RH 7.3) to an Oracle 9i R2 database on a SUN system.
Thank you in advance for any hint.

The iSQL*Plus server will use the environment variables
of the process that originally started the HTTP server.
All users of iSQL*Plus will have this configuration.
I often use two tnsnames.ora files on UNIX. To make sure
the correct one is used by the iSQL*Plus server, I have
to set the variable TNS_ADMIN to the directory containing
the tnsnames.ora file I want iSQL*Plus to use. Then I
start the HTTP server.
What platform is the iSQL*Plus server on? If it is
Windows, it the HTTP server being started as a service
or manually?

TNS Error after Linux Patch

I manage a small instructional Database (Oracle 9i) running on Linux Advanced Server. Everthing had been okay since installation last summer, until a week ago that our Linux Admin applied some patches. Now TNS listener (port 1521) and Oracle Apache (Port 7777) cannot be reached from outside the system. The strange thing is that both services are reported to be running OK, and on the server itself both of them work ok. However, trying from another machine (on the same network) there is neither a TNS listener found, nor an apache service for web (iSqlPlus).
Has anyone seen anything close to this before? Where would you suggest we look?
Thank you

What kind of TNS error you've got? - That's important!
Check that is not local firewall running.
Try stop that firewall using:
"/etc/init.d/iptables stop" - in case of iptables
or
"/etc/init.d/ipchains stop" - in case of ipchains
If it will solve your problem then disable starting of service for future. For example: use the "setup" command.

Dear, I am facing that problem and I need some help. please tell me how the issue was resolved

TNS Error: ORA-12541: TNS: no listener.

I have installed Oracle 9i on machine in Windows XP. When I try to open the database SID in the Enterprise Manager, it gives me TNS Error: ORA-12541: TNS: no listener.
I have checked the Oracle Net Configuration:
Protocol: TCP/IP
Host: PNR18
Port: 1521
In the xp administrative tools, I found that the listener is on start.
When I try to test trough ' Net Configration Assistant' getting same error, similarly with Net Manager.
I don't know if I am using the correct protocol in my case of standalone installation.
Any advice/correction? it would be appreciated. I am giving all the information of TNSNAMES.ORA, LISTENER.ORA, SQLNET.ORA, which is on my machine.
Thanks in advance.

First of all Thanks for suggestions for solutions but still SAME PROBLEM:
Case-1::
I tried according to your suggestion, still SAME error !! I have also configured new DB
with Enterprise MAnager Configuration Assistent - during DB creation same error occured.
1) I have seen in XP service where all listener is running as well as OracleServiceORCL
is also running.
2) OracleOraHome90TNSListener also running with other listeners!
Case-2::
Dear I also delete listener and create new one and also configured Database Description
and tried to do so but still same problem while I am TESTing it with - Net Manager /
Net Configuration Assistant. I have also tried
C:\TNSPING ORCL - it is giving 'ok' result
but when I am using C:\LSNRCTL START listener - it gives me following errors.
Service OracleOraHome90TNSListener already running.

HI,
Please cross check you rpd connection pool details in physical layer like below.
Data source name
Username and password
Or,
Login Weblogic Console with admin username/pwd.
Goto Services -> JDBC -> Data Sources.
Select Lock & Edit button
Select Data Source "bip_datasource" link in the available Data Sources list
Select Connection Pool tab
.... Change the URL|Driver|Properties|Password
Select Save button.
OR,
you have to go to WEblogic Enterprise Manager (http://<server>:7001/em/. Then go to Business Intelligence folder -> coreapplication. Go to "Deployment" tab and then to "Scheduler" tab. Change the database field to point to the new DB and apply changes.
Or,
Please check Database services running or not including TNS listner service also.
Hope this helps.
Thanks

Protocol adapter error is either a missconfigured environment or a network related error. In your case, since you are working with a windows platform and there are other errors related to time out, I suggest you to verify the windows firewall, it could be preventing database from being reached by the oracle client.

ORA-12560 TNS error in protocol adapter. Why ?

I installed on computer1 an Oracle Express 10g server and he runs fine.
Then, on another computer2 in the inhouse-net I installed the Oracle Client.
When I try to contact now from computer2 the Oracle server on computer1
with e.g.
sqlplus.exe myname/mypasswd
I am getting an error ORA-12560: TNS: Error in protofol adapter.
What does that mean?When I enter the same locally on the server machine everything is fine.
Firewalls between the computers are disabled.
Which Oracle services must run on the client (not the server !) machine ?

Ok, my Oracle Client is installed in C:\XEClient
Below I show you the (recursive) output of the 'tree.exe' command (under WinXP)
of the folder tree of C:\XEClient. Where is the directory "network/admin" ??????
C:\XEClient>tree

Receive TNS error when trying to upgrade DB

I receive a TNS error when I try to upgrade a database using the Database Upgrade Assistant. I want to upgrade to 9.2 from 8.1.7. When I click on the database I want to upgrade I receive the TNS error. It never prompts for a username/password@cstring.
I am trying to run this through Windows Terminal Service, is this the problem? I know there are issues trying to run server manager through WTS.
Thanks,
Jim

I'm new to this, but between Oracle 9.0 and 9.2 the required format appears to have changed for the "TNS Service Name" parameter for a "System DSN" in the Windows "ODBC Data Source Administrator". In 9.0 the "TNS Service Name" can be in either of two formats: global_database_name OR oracle_home$global_database_name. One can verify this by clicking the "Test Connection" button on the the "Oracle ODBC Driver Configuration" screen from the "ODBC Data Source Administrator" window. On a 9.2 system only the first format works. I tested this on freshly-installed systems, each with just one Oracle home and the default sample database.
Perhaps this is related to the problem you are encountering. I was able to fix a problem connecting to 9.2 by changing the "TNS Service Name" parameter. The error I was receiving was: "[Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve service name".
Can anyone point me to some documentation on this apparent change between 9.0 and 9.2? Thanks in advance.

Installation Oracle 8i TNS error

I am trying to install Oracle 8.1.7. on windows 2000 OS. I have installed Oracle before but never had the problems I am having now.
I am installing it through a Remote Desktop Connection. I used the typical installation option. At 100% of the installation, it hangs on the net8 optional installation. When I am trying to create the database with the database configuration assistent I get an TNS error while initializing the global database. ORA-12560 TNS protocol adapter error.
What could be the problem here?
Marco

I've never tried installing Oracle 8 on Windows XP machine, so I don't know. And Oracle does not provide download link for software they don't support (like Oracle 8.1.7), 
So your options are upgrade your existing database or try searching 8.1.7 version. I presume you don't have 8.1.7 version, either way you need to upgrade your database anyway.
Give Oracle Express Edition(it's free) a try, using it you can fully utilize advance ODP.NET feature like Database Change Notification. If you choose to download Oracle Enterprise Edition, Oracle won't charge you if you use it only for development purpose.
Cheers,
NH

Discoverer desktop installation on Windows 7 64 OS XP Mode TNS error

I have installed discoverer administrator and desktop in XP Mode on a Windows 7 64 OS. I downloaded the install from Oracle Discoverer 11g Fusion Middleware. I am using XP mode because I believe there is no download for the 64 bit OS in the Windows environment. I have had no trouble with the installation. The trouble comes when trying to connect to a database. I get a TNS error.
I have edited the environmental variable to include tns names. I am able to connect to a database on the network via sql developer but not with discoverer.
One needs to run the xp application within the Windows 7 environment. I have included the environmental variable in both environments (xp virtual and Windows 7) and am 0% successful with discoverer and 100% successful with sql in seeing the database.
Any technical advice?

I am indebted to Praveen Deshpande for this :
You need to create a Windows environment variable TNS_ADMIN that points to the directory where the correct Tnsnames.ora file is held.
On my system, I went to 'Computer - System Properties - Advanced - Environment Variables", created an environment variable TNS_ADMIN and set its value to C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN
Check where your server or other tnsnames file is stored and set the corresponding value.
Then it all worked perfectly.

Hi ;
is there anyone who can help me this ERROR to resolve.
First of all, I use Windows XP system and I tried to connect PHP to Oracle 10g DataBase.But I'd get the ERROR ABOVE.

$co = @ocilogon('hr8','hr8') ; // this is a String with 'username' and 'PSW'
$sql = 'select * from jobs';

if(!$co)
$fehler =ocierror();
echo('Fehler Nr');
echo($fehler ['code']);
echo(' ');
echo($fehler ['message']);
die();

Hi Ken, thanks for the reply. These look like Unix vars. Are they? I am running it under NT in a DOS shell. Do these exist elsewhere?
Incidently, I am in the process of installing OMS and getting a simliar error when creating the Repository.
ORA 12571 TNS Packet Writer Error.
Thanks again.
