I could not able to login thorugh Data Mover and Appdesigner. I am getting below errro
File: SQL Access ManagerSQL error. Stmt #: 2 Error Position: 0 Return: 12541 - ORA-12541: TNS:no listener
But, I can able to login through SQL DEVELOPER.
Also, I can see different DB name in select * from v$database; and select * from PS.OSDBOWNER;
I have set PSDBOWNER name as " PSHRDEV" but when i fire " select * from v$database;" i see " PSHRQUE "

I think you answer your own question
PSHRQUE is your DB name, this should match PSDBOWNER column DBNAME
If your tnsnames reflects PSHRQUE, then you cannot connect to PSHRDEV.
change PSDBOWNER.DBNAME to PSHRQUE and check your tnsnames if PSHRQUE entry exists.
If you are not sure, ask your DBA for the dbname and the correct entires for tnsnames.

Ora-12541 ORA-12154: TNS:could not resolve the connect identifier specified

I am having trouble obtaining an ODBC connection from a client XE to a server XE. ora-12541 ORA-12154: TNS:could not resolve the connect identifier specified
I am new to Oracle.
I have oracle client XE running on my XP pro box.
I have oracle server XE running on an XP pro box on the LAN.
I am trying to connect to the oracle database using ODBC from my client box.
I can logon to the oracle server box through HTTP.
I can logon to the oracle server box by using a connection string in "Command Line SQL" from my client computer. I can then run queries on my client computer. (select * from global_name)
I cannot setup an ODBC connection in windows which will connect to the oracle server box from my client box. (I have no trouble connecting to MSSQL databases).
I can ping my server by hostname or ip address. Both ok.
I can run tnsping XE on the server box and it works. I believe this tells me my server listener is working.
I cannot run tnsping on my client box as it is not included in the download for Client XE.
Windows firewall is turned off on both machines.
I have been reading all over the web for and all attempts fail. Most all help says use Oracle Net Manager or some such tool. They then say go to start\programs\oracle….etc. There is no type program included on the server or the client software. I would like to know here I can download it.
XEClint\Bin is the firs entry in my PATH. The tnsnames.ora, sqlnet.ora, and listner.ora files are there. I have been to http://www.oracle.com/technology/software/products/database/xe/files/install.102/b25143/toc.htm several times. My tnsnames.ora are identical to the ones in the example except for the host =.
I have 3 tnsnames.ora files on my computer:
Directory of c:\

Directory of c:\Documents and Settings\All Users\Application Data\Microsoft\Net

Directory of c:\XEClient\bin
04/03/2008 11:43 AM 635 tnsnames.ORA
1 File(s) 635 bytes
They are all identical.
When I ran lsnrctl status on the server the results were the same as found in other articles in the web site. Default service XE
I have the Oracle in XE Client driver in my windows ODBC driver list of the client box. And other Oracle drivers.
It appears I am lost.
Any help would be appreciated.

I cannot setup an ODBC connection in windows which will connect to the oracle server
box from my client box. (I have no trouble connecting to MSSQL databases).How you tryed to do that?
On which step you have problems?

ORA 12224 - TNS: No Listener problem

Hi there,
I have SQL*Plus working on client A (Sun Solaris, 9i), connecting to server C (Windows NT, 7.3.4)
From client B (Sun Solaris, 8.0.6), trying to connect to server C using the same TNSNAMES.ORA, same user & instance, I get the error :
ORA-12224: TNS:no Listener
This error, to me, means that the Oracle listener on server C is not working. Which is not possible, because it does work from client A !
Where did I go wrong ?
Could this mean that client B does not have network access to server C (client B is in DMZ, but should have all required accesses) ?
Thanks in advance !
Best regards,
Jerome

Do you have a firewall between the server and the clients and are allowing only 1521 through? If so, read on. Oracle on NT by default uses a non shared socket impl which essentially means that even though the original request comes in on 1521, the server bequeaths the connection to a thread listening on a different port (a high port) and sends a redirect request back to the client. When the client attempts to connect to this neew port, the firewall blocks it. The way around this is
1. Get a firewall that recognizes SQLNet like checkpoint and allow all SQLNet traffic through
2. Open up all high ports (I can hear the sysadmins wanting to kill you)
3. Get Oracle to use SHARED_SOCKETS (if applicable to your platform/version. Update the registry to set SHARED_SOCKETS = true. This is a feature in Winsock2.0 that allows a socket to be shared through IO completion ports. (There is a great whitepaper on Metalink/Technet. Search for SHARED_SOCKETS)

I am getting an error ORA 12514 TNS: no listener error

Please help me out with this error as i try to access Enterprise Manager Console or any other module with SYSTEM and MANAGER as the password i get this error.

Few obvious question... please check and revert back
1. Have you configured the TNSNAMES.ORA correctly on the client machine. Please check the hostname. If you have not given the IP of DB server then make sure the IP address is there in the "hosts" file, so that name can be resolved
2. Is the listener-up on DB server and configured on the same port that you have mentioned in TNSNAMES.ORA?
3. Is the database registered in the listener?
You can use net-assistant to check and configure the same.

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
which knows NOTHING about NTS Authentication.
SQLNET.AUTHENTICATION_SERVICES = (NONE)
or just remove the line or whole file.
Also need to be sure that ipchains is disabled on *NIX system

Oracle 10g XE: ORA 12514: TNS ...

Hello,
I installed "Oracle 10g XE Database" in a Windows 2003 Server platform.
Sometimes, when I restart the machine, database gives me the following error:
ORA 12514:TNS:IL LISTENER NON è ATTUALMENTE A CONOSCENZA DEL SERVIZIO RICHIESTO NEL DESCRITTORE DI CONNESSIONE.
DESCRIPTION: AN UNHANDLED EXCEPTION OCCURRED DURING THE EXECUTION OF THE CURRENT WEB REQUEST. PLEASE REVIEW THE STOCK TRACE FOR MORE INFO ABOUT THE ERROR AND WHERE IT

I can solve it restarting "OracleServiceXE" and "OracleXETNSListener".
My colleagues cannot resolve this problem and they had to install Oracle 9i.
It is all ok with Microsoft XP Professional.
Is there any patch available to solve this problem with Microsoft Windows Server 2003?
Thank you very much.
Massimiliano

it seems not to be a bug but a configuration issue.
12514, 00000, "TNS:listener does not currently know of service requested in connect descriptor"
// *Cause: The listener received a request to establish a connection to a

// 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.

ORA-12541: TNS:no listener. (HY000)

Hi,
I created a DSN A and added the name to my connection pool in OBIEE 10G rpd. When i click on "Test Connection" in the DSN, it connects successfully. However, when i create an ad-hoc report in Answers with a subject area that uses the same connection pool, i get the no listener error:
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 16001] ODBC error state: S1000 code: 12541 message: [Oracle][ODBC][Ora]ORA-12541: TNS:no listener. (HY000)
What am i doing wrong?

what I am referring to is the post above which says the following
If you have Oracle client installed why you need DSN?!!!
just use hostname:port/Service at connection pool by selecting OCI
before that using command use tnsping <tnsname> that should return tnsentry if not check setting

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.

9.2.0.1.0 - OEM - XP home - ORA-12541 TNS: no listener

I have installed 9i (9.2.0.1.0) on Windows XP home edition and can connect to database with SQL Plus but get ORA-12541 TNS: no listener error when I try to connect with OEM. I saw someone else had this problem in Febuary and he sadly got no replies, hopefully someone will be able to help me (us) out.

I guess you now have answers.
1. Check if listener is running
lsnrctl status <listener name>
2. Check port number and SID used
3. Check TNSNAMES for correct Port and SID name
4. Check error details in $HOME/network/log

PL/SQL Debugger and ORA-12541: TNS:no listener

I installed SQL Developer on my PC (Windows XP). I have a connection to my devlopment database on server (Solaris, Oracle 9.2.0.6).
I create a procedure and compile it successfully. Now I want to 'debug' it. I click on the Debugger (ladybug), set my parameter value and click on 'OK' in the Debug PL/SQL window. In the Debugging log I get:
Connecting to the database Banner devl.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: ALTER SESSION SET PLSQL_COMPILER_FLAGS=INTERPRETED
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '130.207.xxx.xxx', '4000' )
ORA-30683: failure establishing connection to debugger
ORA-12541: TNS:no listener
ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
Process exited.
Disconnecting from the database Banner devl.
What listener is it looking for on my own machine? I don't have J Developer and I'm using a remote database.
I found the thread on setting the 'Prompt for Debugger Host for Database Debugging'. Enabled that and tried debugging again. Got the prompt for entering the IP of the Debugger Host. Tried the database server. So I got:
Connecting to the database Banner devl.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: ALTER SESSION SET PLSQL_COMPILER_FLAGS=INTERPRETED
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '130.207.xxx.xxx', '4000' )
ORA-30683: failure establishing connection to debugger

ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
Process exited.
Disconnecting from the database Banner devl.
The answer is probably right in front of me, but I just can't see it. Is something mission on the database server?

I am running SQL Developer on Windows XP Professional and I was experiencing the same problem.
When I started the debugger I got the message from Win XP that Windows Firewall will block some features of the program (being the PC at work I don't have admin privileges on it). I accepted this, not knowing which features would be blocked.
Then, the debugger was just hanging. After a while it timed out and came back with exactly this error message.
I restarted the SQLDeveloper and tried again without much success. This time though I didn't get the Windows Firewall message.
After another few trial and errors I figured out that the Firewall must be blocking connection establishement on the client site i.e. on my PC.
It was the CALL DBMS_DEBUG_JDWP.CONNECT_TCP that was hanging.
As the system admin disabled the Windows Firewall on my PC the debugger started working. We have a luxury to disable local firewalls as there is one that protects our network from outside traffic. People who cannot afford to disable the Windows firewall will have to tinker with the firewall itself and configure it in such a way that it allows traffic on certain port range (4000...4999). Then in SQLdeveloper you will have to go to Tools->Preferences->Debugger and tick Debugging Port Range. The chosen range should match the port range on the Windows Firewall side.
By the way, in the call to CALL DBMS_DEBUG_JDWP.CONNECT_TCP the first parameter is the IP address of your PC and the second one is the port used for debugger connection with the database server. If for some reason the IP address chosen by the debugger is not your IP address (you can find your IP address as follows: Start->Run->cmd; then use command ipconfig), you will have to tick "Prompt for Debugger Host for Database Debugging" on your Debugger Preferences. This way you'll be able to chose the IP address yourself.
Good luck!

Hello Nicholas,
Thank you for your suggestion.
But i do not think it is really required to change P96 tnsnames.ora.
Because, T72 database is in a Linnux box where several other DB are also there.
(Our landscape,NOn-PRD DB instances are together in 1 linux box)
DB13 jobs of other instances are working fine.
Only difference is T72 sap instace is a windows server where as other instances are in AIX.
In DB13c, windows system is configured as without ABAP server .
                 UNIX systems as With ABAP server.
All were working with this configuration till few days ago.
Thank you.

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

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.
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 1056: Unknown error
Thats the whole story....hope this time you will find easy to give solution.
