Networking And Gateways :: ORA-12514 - TNS - Listener Does Not Currently Know Of Service Requested In Connect Descriptor
Feb 9, 2010
I have oracle 11g on windows xp. I can connect to oracle by SQL Plus without any problem, but when i want to connect to oracle by Toad or SQuirrel i see this error:
PTM Coding: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
im getting error ORA-12514.our prod db runs under default listener.nw i have configured another listener.if i try to connect from the loacl im grtting above error,bt im able to tnsping from the local system.

We are trying to configuration the Dataguard in Oracle Database 10g Enterprise Edition Release 10.2.0.1.0. While we check the lsnr configuration the following error has occured.

I am facing problem "ORA-12514" error. my database is register in listener but when i connected throw "sqlplus" then i got "ORA-12514" error.

I am new to oracle DBA. I have just installed the oracle on centos. when i create the oracle database for the first time then listener created and worked sucessfully. but when i stop the listener and start again. I get message "Listener does not currently know of services requested in connect descriptor.
I am trying to connect to Oracle 11g using ODBC.I created a data source name from Admistrative Tools->ODBC Data Sources.I selected Oracle in OraClient11g_home1 as the driver. I tested the connection and it was succesful.I tried to connect from visual studio. I used the Data Source as Microsoft ODBC Data SOurce. Selected my DSN from drop down (LORAC). I gave the user name and password and got the followign errors:
ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA
This is my tnsnames.ora located in C:oracleproduct11.1.0client_1 etworkadmin directory. # tnsnames.ora Network Configuration File: C:oracleproduct11.1.0client_1 etworkadmin nsnames.ora # Generated by Oracle configuration tools. LORAC = (DESCRIPTION =
[code]...
When i do tnsping LORAC, i get OK. When I do tnsping of the other service name i get Failed. However when I try to connect to that service from Visual studio I get a differnt set of errors:
ORA-12154: TNS:could not resolve the connect identifier specified
I had assumed that as the test connection from ODBC Administrator had worked I would be able to connec to my database from viusal studio. Is there something wrong in my tnsnames.ora? The content or its directory location?
I have ora-12520. I run Oracle 11g on Red Hat 4 64 bit. Actually I have RAC but one node is down and I work only with up one (connection string point directly to listener of running node). I run test with not too big loading. select count(*) from v$sessions gets ~ 200 in maximum loading, but after half minutes I get this error in my logs. Each time, lsnrctl services show that all is right. It shows one service with one handler. I see nothing in alert.log. This is very strange, I know, and I'm sure that this is an actual alert.log because, I see there other events in actual time. Most important: I have SESSION parameter set to 600 and PROCESSES set to 400 so this must be enougha...
ORA-12518 Tns: Listener does not currently know of service
from application server using client 10g to connect our database.This problem happens only in application server and we tried from another server we can connect to database easily but problem only in application server.
this error since TNSNAMES and network are properly hosted since there no network disconnection betwwen database server and application server.
One of our requirements is to secure the listener and other Oracle services by running them as a local OS account rather than as LocalSystem on the server.
I created a local OS account (assume it's named oracleuser), assigned it to the User and ORA_DBA groups on the server, and then I went to the Local Policies and added oracleuser to "Deny log on locally" and "Log on as a service".
I opened up the Services utility and stopped the four Oracle services we have running (OracleMTSRecoveryService, xxx_home1iSQL*Plus, xxx_home1TNSListener, and OracleServiceMYDB). I changed the "Log on as" for each service to oracleuser with its password (copied and pasted so I know there are no typo's), and restarted the services.
All the services except the listener started up. Attempting to start the listener caused the following error:
"The xxx_home1TNSListener service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service."
I tried rebooting the server and had the same result.For now just the listener service has been switched back to logging in as LocalSystem while the other services continue to use the local OS account and the database seems stable, but I do need to figure this out.
I have a database up and running (including listener) on machine A. From that machine, everything seems fine. However, when I try to connect to it from another machine (say, machine B) on the network, the connection cannot be established (exact message: connection to database failed: The Network adapter cannot establish the connection).
I can successfully ping machine A from machine B. The machine A db is a default install (ORCL).
Is it possible the DB listener is not configured properly to connect to remote clients? On machine B, I have oracle tools such as SQLPLUS, Oracle Net Manager, and Net Configuration Assistant.
I am using Oracle 10g and when i start my server then my database is running and my application use this database.But after 15 min automatically application show this error

When i'm trying to connect my already-existing database, i get an error: "ORA-12505,TNS:listener does not currently know of SID given in connect descriptor.The Connection descriptor used by the client was: localhost:1521:xe".
i can't loose the builted tables and the information stored in them.My listener.ora file is :
I am using oracle 11.2.0 in linux platform.i have created a listener for the asm database. and i am using non default port of 1525 whenever i go for lsnrctl>status always shows for the port 1521. i don't want the default port 1521 and i have changed the local listener as listener1 with port 1525 protool tcp in spfile and registered with the asm database.Is there any option to change the default listener as listener1.
also,everytime when i give lsnrctl>show current_listener it is showing "listener"
i have set the current-listener to listener1 and save_config listener1 and reloaded.After exit and enter lsnrctl>status it will show for port 1521 When i attempt to start listener1 every time. it will prompt listener1 is already running.
In one of our RAC envrionment, we have more than 15 databases in a server running in AIX Operating system.the Listener file I am able to find only one entry (SID). But while trying to execute lsnrctl status it displays all the 15 SIDs in the list hosted in the ser ver. Not sure how it works?
As we created another one new database in the database, where i need to add this SID in the listener.ora file to reload the listener.
I get this error when I try to connect to this database service as another user. I can connect to it as sys without any problem and the database is up.
And when I check to see whether the listener is running for that service, using lsnrctl status command, it shows that the service is UNKNOWN. What does this status mean?

I installed Oracle 9i under W2K with preconfigured DB (SID=ORCL), after that I intalled Oracle developer suite and everything is OK but, When I created second DB (SID=SUMM), I get "ORA-12154: TNS:could not resolve service name" when I tried to connect with :

NB: I have no problem when I use

What I'm trying to do Establish a remote connection to an Oracle 9i R2 9.2.0.8.0 database using "Oracle Provider for OLEDB 9.2.0.7.0" (I was unable to find an 9.2.0.8.0 equivalent) on a Windows Server 2008 R2 64-bit machine.
My database is oracle 9i when try to connect oracle database using putty to AIX server like..

then it is also successfully connected to database..what is the problem .
My server database is not connected today whenever I try to connect it. It was working properly till yesterday but today morning when I came to office and want to connect with server then my database server show the message "ORA-12154 TNS: could not resolve the service name" and not connected.
I can able to login to the database through an user A. But when I try login as B,I am getting the follwing error. ORA-12154: TNS:could not resolve service name...I am using the following method.
1. Login to the database server via putty. 2. sqlplus A/****
for the user A,the step2 is working fine. But the same step is failing for the user B.And the user B is trying to connect to the database from the same server as the user A logged in to the database successfully.

I have overwritten tnsnames.ora file with newone. In new tnsnames.ora file I have added new host string, remaining all unchanged.
after that, when trying to connect using sqlplus(from windows machine, sqlplusw.exe), working fine. But when trying to connect through putty getting error.
ORA-12154: TNS:could not resolve service name
for the same reason my scheduled cron tab can not run export backup. cron tab error is

I am suspecting problem may be due to file accessing permission related issue. But cant solve it. Current tnsnames.ora files permission is
I have a requirement wherein I need to access the MS ACCESS database table from Oracle Client.I have created ODBC data source and have configured tnsnames.ora and listener.ora for the same. As a next step I am trying to configure HS init file for hsodbc connection but couldn't find the directory hs in $ORACLE_HOME (<ORACLE_HOME>hsadmininit******.ora). Any patch that needs to be applied for hsodbc connection in the server.
Which parameters are required in init file for 'Dynamic Listener Registration'? (for default port/ protocol). I understand that Local_listener is required only if we are using not default protocol, port.
Also which cases we need listener.ora file? I understand we need it for 'Duplicate Database' using RMAN as well as for 'Data Guard'. what else will need it?
I am having a problem getting my listener to start.
