TNS name resoultion error

Hi,
When I try to ping a tns alias using tnsping, I get the error , TNS - 03505 : Failed to resolve name.
But I am able to connect to the same database from my SQL plus using the tnsnames.ora file @ the location : C:\DEVSUITEHOME_1\NETWORK\ADMIN.
The entry for the corresponding alias exists in the tnsnames.ora file at this location.
Can somebody tell me the reason for this error and also what needs to be changed to be able to tnsping the alias succeffully.
Thanks much!

Thanks much!Please execute both the tnsping and the sqlplus connection at a command line, then use copy and paste to show us exactly what your full command line is and exactly the full response from oracle.

Hi,
I am a tech at a failing company. Unfortuneatly some users still need ADI installed and working with very limited resources to troubleshoot oracle.

Does anyone have any ideas what else I can check. I'm a Unix person, not a Windows person, which is making it even more complicated. If I was on Unix, I'd just blow everything away and start again from scratch, but since I'm not sure how to remove all traces from the registry, etc., I don't want to try that on this machine. There was already one other database created, but it's not goign to be used.
Any help would be greatly appreciated.
regards,
Tarisa.

hi,
thanks for the info. the problem, as it turns out, was that I was connected to the db server via a terminal service (Microsoft Management Console), which for some reason caused probelms with TNS. After I connected directly to the machine using VNC, I was able to create the database with no problems. strange but true.

Tarisa.

Connect to Oracle through ODBC - TNS: No Listener Error

Hi All,
I've been trying to chase this problem down for over a month now and I have had no luck. When I try to connect to an Oracle server through MS Access I get the TNS: No Listener error. The kicker is when I go to the odbc data source administrator in windows I am able to connect to the oracle server. My computer is windows 2007 and I have Oracle 11.2 installed. Could anyone assist?
When I type lsnrctl start in the command prompt it says it has been already started.
Here is my tnsnames.ora:

I suggest you move, remove, rename, delete or otherwise move the listener.ora file out of the way.
listener.ora is NOT required to start or utilize the listener
open Command Window after doing as directed above then issue the OS commands below

Thx.

Yes, the XP firewall is running. During the Oracle instalation it poped up twice, but I selected 'Unblock'. I can't turn it off because it is running using the domain settings, but I can add exceptions (programs or ports). Port 1521, tnsping or sqlplus are not blocked and there is an option 'Display a notification when Windows Firewall blocks a program' witch is checked.

TNS names can't be resolved

Hi All!
I try to connect to a database and the error message that TNS names can't be resolved. tnsnames.ora is copied from the PC where the connection works. Only one instance of Oracle client (9.2) is installed. I tried to add a TNS names in Net Assistent. It worked and the test within the assistent was successfull. The tnsnames.ora was also adjusted. But! I don't see the service in NetManager and I can't add any service there. The NT user is a member of the administrator group. I also try to connect using SQL plus, Excel, Enterprice manager - it doesn't work. Any ideas?
Is there any Windows service for the TNS? How it calls? I tried to check it with lsnrctl status but the command is not exist. Only client is installed on the PC.
Thanks,
Andrej

If you copied it from another PC then check that you have the correct entries in sqlnet.ora
For instance, in sqlnet.ora, if the parameter NAMES.DEFAULT_DOMAIN=yourserver_name.domain_name is not in use (commented out) and your net service name in[b] tnsnames.ora is mydb.yourserver_name.domain_name , when you try connecting with mydb as the connect string, you will get that error.
To resolve that, you either enter the connect string as mydb.yourserver_name.domain_name or uncomment NAMES.DEFAULT_DOMAIN in sqlnet.ora(add it if it does not exist) or change the net service name intnsnames.ora to mydb

Local Database, TNS Names & ORA-12541: No Listener

I am trying to get IFS working on our new Windows 7 machine and the entire department is scratching it's head right now.
I have gotten Oracle 11.2.0.1 installed and finally being seen by the ODBC thanks to the past threads on the forum mentioning the System Environment Variable. However, now I need to be able to get the program to sync the information that I can pull from "MPRDSP6", the one working ODBC connection right now.
In the past with Oracle XE we had the following in our TNS Names file:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = COMPUTER.company.local)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
The XE was created whenever Oracle XE was installed and we just added in our MPRDSP6 at the end of the TNS Names file. This was what we used when making the local copy for our personell that would travel and need access to the database.
However, with Oracle 11.2.0.1, there was no TNS Names file whenever it installs and I had to create it --> Inputting our XE entry and the other, MPRDSP6.
Upon trying to 'Test Connection' in the ODBC screen I get:
Unable to Connect
SQLState=S1000
[Oracle][ODBC][Ora] ORA-12541: TNS:no listener
Whenever I try to sync the MPRDSP6 with the local copy of it (named local_db), I am getting an error from the program saying:
Could not find the Local Oracle Data Folder. Please make sure your Local Oracle is running and that you have set the Local Database Creator.
I am assuming this is simply because there is actually no database in existance: it is just in the TNS Names.
I am Running Windows 7 x64
Forgive me if this is a very simple fix as I am completely new to the world of Oracle.
Thanks in advance for any help!

Having the same issue, trying to connect IFS Sales and Marketing. In my case, I am using Oracle Express 10g, Windows 7 32-bit. My ODBC DSN can find the "host" server, but does not seem to find the local Oracle Express instance.

How to solve ORA-12560:TNS:protocol adapter error?

I'm trying to use sqlplus on Windows 2008 R2 which is installed on VirtualBox to access an Oracle 11gR2 database on Red Hat Linux.
I'm sure that the database on Red Hat Linux is up and tnsnames.ora is a copy from another machine which is used by another application to connect to the same Oracle database.
When I run sqlplus, I got the ORA-12560: TNS:protocol adapter error.
sqlnet.ora
SQLNET.AUTHENTICATION_SERVICES = (NTS)
Both sqlnet.ora and tnsnames.ora are located in c:\app\administrator\product\11.2.0\client64\network\admin folder.
The registry ORACL_HOME has c:\app\administrator\product\11.2.0\client64.
echo %ORACLE_HOME% incommand window returns %ORACLE_HOME%
echo %ORACL_SID% in command window returns %ORACLE_SID%
If I set ORACLE_HOME to another folder, I will get the following error:
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
So, I believe the ORACLE_HOME in registry has the correct value.
I have also tried set ORACLE_SID to the service name listed in tnsnames.ora but sqlplus still returns the ORA-12560:TNS:protocol adapter error.
For unknown reason, the value of ORACLE_HOME and ORACLE_SID I set by using set command will not persist after I close the command window that I set the values.

It make NO sense do to as above when attempting to connect to Oracle DB on *NIX

or just remove the line or whole file.
Also need to be sure that ipchains is disabled on *NIX system

TNS-12560: TNS:protocol adapter error

Hi,
I recently upgraded from oracle 9 to 10g and I get the error above.
I created a new database I CAN connect to it using sqlplus (from console), but I cannot connect using any ide.

Any help is appreciated.

You didn't describe how you performed the upgrade process. But it looks like you performed a migration process instead. If there is no listener service listed it's because it has never been started, or even configured. You should use the netca or the network manager to configure the listener and start it. The first time it starts it shows an error on windows platforms because the service originally doesn't exist, once it is created it displays the listener status.
Please check the name resolution mechanism. If you are working on dhcp assigned IP or if you have a fixed IP. In case you are working with dynamic IP address you should configure a loopback adapter, and I suggest you reading this reference: Connectivity. Loopback Adapter.

Tns-12560: TNS protocol adapter error on linux

I've installed an oracle 10g database on linux 4.6 in a VMWare image. After opening an x term window within the image, I'm getting a tns-12560 error when both running tnsping and opening a sqlplus session as a database user. The listener and database seem to start fine. I've included entries for sqlnet.ora, tnsnames.ora and ORACLE_SID and ORACLE_HOME values for my user.

One of the more common issues causing 12560 is that the host in the listener.ora does not match current host name. Commonly caused by dhcp.
Your tnsnames.ora looks for cgbu-p731v2.us.oracle.com
Your listener.ora want to listen for cgbu-p731v2.us.<<my domain entry>>.com
Your hostname is ??? (enter 'hostname' at command line)

TNS-12560: TNS:protocol adapter error - Of a different sort

Hi ,
Have a unique problem.
System :- Win 2K
I have installed 9iDB & 9iDS. They were working perfectly fine. I was able to connect to DB from forms. But due to some restrictions i had to resort to 6i forms.
Now i installed 6i forms on the same machine. But when i try to connect to DB i get the TNS:Protocol Adapter error. I am sure the instance and the listener is up and running. Because still i am able to connect from 9i forms. The DB name is MYDB.
The error i am getting is :-

Did you try copying 9iDS SQLNET.ORA and TNSNAMES.ORA to 6i Home ?

TNS-12560: TNS:protocol adapter error TNS-00530: Protocol adapter error

Unable to start listener service.
Running Oracle Database 11gr2 on Windows 7.
I just installed Oracle with the "install software only" option.
Already set up the instance, the database, the dictionary views, etc.
Created tsnames.ora, sqlnet.ora and listener.ora as shown below.
Before installing Oracle I followed the instruction on Oracle
documentation to install a Loopback Adapter.
It is set up as the primary adapter as indicated on the
instructions. The name is "gabylan" (previously the computer
name was "P4". I set up the "hosts" file as indicated, the oracle_hostname
variable, etc. as you will see below. I don't know if it's important to "uncomment"
the line on the "hosts" file for the "localhost" entry, I left it
as it was originally.
Services currently in "Started" Status:
OracleServiceorcl
Oracle orcl VSS Writer Service
OracleMTSRecoveryService
OracleOraDb11g_home1ClrAgent
OracleServiceorcl
Below is a summary of the error message and some information
about my system setup to help you diagnose my problem.

Step 2 - display the contents of the %ORACLE_HOME%\network\admin\tnsnames.ora file on the machine running sqlplus.
