ORA-12514 Listener Error on server

How come I keep getting a error message that the TNS Listener does not currently know of service error (ORA-12514) only on my server when trying to connect from the same server as the 10G 10.2.0.3. database is running on? If I do not use the @ connection it works fine as the ORACLE_SID environment variable is set to the instance name in the tnsnames.ora file. My 8i and 9i clients have no problem connecting to this server and the 10g database using the @ in the connection string but I believe their .net services files (tnsnames.ora and sqlnet.ora) are configured native to the versions configured on the clients (8i or 9i).
This is the error from the server and a sucessful connection not using the @ sign in the connection string:
SQL> connect sys@prod as sysdba
Enter password:
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in
descriptor
Warning: You are no longer connected to ORACLE.
SQL> connect [email protected] as sysdba
Enter password:
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
SQL> connect sys as sysdba
Enter password:
Connected.
SQL>
Is there something wrong with the listener.ora file on my server? Here is the current listener.ora file current on the host server (10g 10.2.0.3), it's tnsnames.ora file and below this a 9i client tnsnames.ora file which is sucessfully using a tnsnames.ora connection using username@server_name/password.
Any help would be greatly appreciated:

hello, please try to comment the line in the sqlnet.ora file on the client and try again. If it works do the same on the server. Or you can set the value to NONE instead of (NTS).
Try this and let me know - this can be the reason why you cannot login without password as sysdba. When you are not using @ in sqlplus from the server these files are not read that's why it works.
If it does not work yet in the same file try adding the line:
NAMES.DIRECTORY_PATH= (TNSNAMES)

ORA-12514 & Listener Status Instance status Unknown issue

Dear All,
Database Version - 10.2.0.5.0
Operating System - Windows XP
I am using Oracle 10g version, which has two services (bit10g and ora10g) installed on it.
Service ora10g was working before upgradation of Database to 10.2.0.5.0 and it was fine.
On upgradation I was unable to start and connect using ora10g so I created another that is bit10g.
Service bit10g was working fine for quite a long time. The last I worked and connected was on thu and it was connecting with no issues.
Now when I am trying to connect to database today I am unable to connect as I am getting
ORA12514 - TNS:listener does not currently know of service.
Secondly I tried to search forums which guided me to check the Listener Status.

ORA-12560 listener error WIN XP ora10g

I connect database by sqlplus / nolog normaly, but my listener cant start. I get ORA-12560 error.
1- I my tnsnames.ora_OLD and listener.ora_OLD and crate new one but still error;
2- i do
net stop oracleserviceora10g
net start oracleserviceoa10gBut still error.
3- i set ORACLE_HOME and ORACLE_SID and still error...
Someone can help me??
Tks,
Elber.

Elber,
You can turn trace on and see what's wrong. This is the first step for you solve your problem.
Put the following line in your listener.ora file and then try start again. After this, look into trace file.
TRACE_LEVEL_listener_name=user
TRACE_DIRECTORY_listener_name (By default the directory is ORACLE_HOME\network\trace on Windows NT, and the file name is listener.trc)

ORA-12514 Listener does not currently know of service

I am trying to connect a client workstation to the Oracle server. OS for the server is Windows Server 2008 (64 bit) and OS for the client is Windows XP (32 bit).
Oracle Database on the server is 11g 64-bit (11.2.0.1.0) and the Client software is 11g 32 bit (11.2.0.1.0).
I have set up the client (using the Net Manager tool) with the following parameters:
Service Name: drsdb_server
SID: greyed out
Connection Type: Database Default
Address:
Protocol: TCP/IP
Host Name: [IP address of the server]
Port Number: 1521
I also set up listener parameters (though I don't know that it is necessary) with the Net Manager tool:
General Parmeters:
Listener Name: LISTENER (this is the Alias retrieved with lsnrctl on the server)
Listening Locations:
Protocol: TCP/IP
Host Name: [IP address of the server]
Port Number: 1521
Database Services:
Global Database Name: drsdb
DB_NAME is not set on the server
DB_UNIQUE_NAME on the server is defined as "drsdb"
SID on the server is "drsdb"
These parameters are not defined on the client.
Everything works as expected on the host (server) machine as expected (SQL*Plus, SQLDeveloper, etc.)
Any ideas?
Thanks.

Still the error occurs. Could anyone suggest what can be done.

The error basically means that the connection service which you are requeting in your connection string is not yet to known to the listener of yours. See here the output of the listener's supported services from your post.

It clearly shows that the listener is only working to listen for the PLSExtproc service which is meant for external procedures.
Is the database just started? If that's the case than it may take a while to get the PMON register the db with the listener. Or you can issue,
alter system register from your db's sql prompt which can ask listener for immediately register the db with it. Try this command and post feedback. If that won't work than you may have to manualy register your db with the listener.

I created Stby DB with the minimum parameters required, so that I configure BROKER and see it magic, but badly stuck in this situation here. I have read many docs related to this..but can not fix it unfortunately.
Please guide me from your own experience as note ids, blogs are not helping me here...
Bundle of thanks.
Best Regards

Hi,
Your listener.ora file has SERVICE_NAME = dg_db2.domain whereas tnsnames.ora file has SERVICE_NAME = dg_db2.
Check in your database for exact service name and reflect the same in both the files.
SQL> sho parameter service_names
Restart the listener and try connecting.
Thank you!!

TNS listener error "ORA-12514: TNS:listener..."

Hi all,
I have a problem with my listener on Oracle 11.2.0.2.
I am more of a developer than a DBA, and I do not have a DBA to consult, so I hope you can address me, please.
I have 2 DB instances running on the same machine ORCL and ORCL2 on port 1521, both using the same listener "LISTENER" as well on port 1521.
In my TNSnames I had to add yesterday as well a new entry to a DB (ORCL3) hosted on a different machine.
Since then, I can connect to ORCL and ORCL3 without problem via sqlplus, but I get the below error when I connect to ORCL2:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
I think the answer is to have to separate listeners for ORCL and ORCL2, but I have had several failed attempts.
Can you please advise on what I need to do? I have looked at various sites, but if you are not too experienced with listeners, they are not really very clear.
Thanks

Hi, thanks.

Hyperion startup error -ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

Hi All,
While restarting the hyperion service we see this exception. Nothing was changed on the hyperion server. Checking with DB team if anything was change on their end.
Caused By: weblogic.common.ResourceException: weblogic.common.ResourceException: Could not create pool connection. The DBMS driver exception was: Listener refused the connection with the following error:ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

We don't have oracle client on our end, so this is not a tnsnames issue. This is preventing all the hyperion services coming up.
Thanks,

The listener is up , the message is from the listener indicating the listener does not know of SID/SERVICE name that you are giving it. Manually connect to the db using sqldeveloper in order to make sure the parameters you are providing are working. Pay special attention to SID vs SERVICE_NAME. Then try to open config tool and go back to your database connection info. Reconfigure your database connection. It will likely you will find your connection error there. Also sometimes the config tool has trouble figuring out whether you mean SID or SERVICE_NAME. You can open advanced properties on the connection in configtool and specify / or : in the url.

TNS Listener -ORA-12514 error following database shutdown - Oracle 11g

Hi
I have hit a problem with my oracle development database.
When in sqlplus I executed the shutdown command, but nothing happened for several minutes and it was just hanging. No messages were displayed to the screen. The only thing was to close the command window. When I open sqlplus again and enter in the user name password as sysdba I am getting ORA 12514 TNS Listener could not resolve service in descriptor. This is odd as I could log on before and use the database. So I thought that the services were still shutting down I waited, and using the Windows snap on tool for Oracle 11g, I restarted the services on the database, but this has had no effect.
Even using EM made no difference because I couldn't log on to perform a startup or recovery.
So, please does anyone know how I can fix this?
Thanks

open Command Window & do EXACTLY as below; line for line
sqlplus
/ as sysdba
shutdown abort
startup
exit
COPY command & results from above then PASTE all back here

Cause
Oracle Workflow software was installed but the packages/repository have not been created.
RPE-002053 indicates that Oracle Workflow Installation is incomplete and OWF_MGR schema should not be empty.
Solution
1) From Oracle Workflow ORACLE_HOME:
- Run $ORACLE_HOME/wf/install/wfinstall.csh
- Follow Oracle Workflow Configuration Assistance screen to install Workflow packages under OWF_MGR schema.
2) Review if there is any error after running the script.
3) Re-deploy OWB Process Flow.
