ORA-12541: TNS:no listener error from client mechine

We have oracle 11g server from onsite and I am trying to connect from offshore client.But I am getting error
From SQL plus i am getting the error,
ORA-12541: TNS:no listener
and from SQL Developer I am getting the error,
IO Error:The network adapter could not establish the connection
I am able to Telnet the host with proper port.Onsite peoples able to connect the database from any client using the same TNS names configration I am using.
What are the possibilities to get this errors ?
Please guide me on this.

Hi
Thanks for reply.I checked with onsite DBA for listener and it is up.If you have an on-site DBA why aren't you working with him to solve the problem?
Since you assert that other client machines are able to connect to the database, the issue must be with your own setup. I strongly suspect your tnsnames has a bad entry. Please compare it to the same file from a working client. Also, show us the contents of your tnsnames.ora file.

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

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.

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.

Using a DNS address in tnsnames.ora and a hardcoded IP address in listener.ora or a DNS name not translating to the same IP address the tnsnames.ora DNS translates to, is a known source for ORA-12541.
The listener tries to establish communications to the client, using the IP address it gets from listener.ora or by calling nslookup.
If they don't match: kabloey.
Been there, done that, and a little searching would have helped you out.

The Listener in SNAPSHOT server and the MASTER server - started
I can do the same from different country of the other server with the same tnsname works.
But only this perticular site have issues since Oct 27, 2011 onwards. The last successful replication from that snapshot site to master is on Oct 27, 2011.
I can connect to the SNAPSHOT Site and from there i can connect to the master using any profile to the master.
But only when i replicate from the snapshot site using the script then i am getting this 12541 no listener error
Please help.
Thank you,

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!

ORA-12541: TNS:no listener after upgrading from 11.1.0.6 to 11.1.0.7

After upgrading from 11.1.0.6 to 11.1.0.7, I get the error: ORA-12541: TNS:no listener.
I have attached my tnsnames.ora, listener.ora and my sqlnet.log.
I have tried deleting the listener and re-adding it and I get the same error.
I have tried adding a new database and it errored at 97% because it couldn’t connect to the listener, but still seemed to create the database.
Any suggestions would be appreciated

Hi,
What is your ORACLE_SID name of your database. Have you checked in given above output there is two things:
1.
Service "orcl.us.oracle.com" has 1 instance(s).
Instance "orcl", status BLOCKED, has 1 handler(s) for this service...
Service "orcl_XPT.us.oracle.com" has 1 instance(s).
Instance "orcl", status BLOCKED, has 1 handler(s) for this service...
The command completed successfully
The status BLOCKED is coming instead of READY
2. From
+"+
+my listener.ora file:+
+# listener.ora Network Configuration File: C:\Oracle\product\11.1.0\db_1\network\admin\listener.ora+
+# Generated by Oracle configuration tools.+

+(DESCRIPTION_LIST =+
+(DESCRIPTION =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = tebxjt)(PORT = 1521))+
+(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))+
+)+
+)+
Here what i feel complete linstner.ora should be have two parts one LISTENER and another SID_LIST_LISTENER :
LISTENER =
(ADDRESS_LIST=
 (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
 (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))
SID_LIST_LISTENER=
(SID_LIST=
 (SID_DESC=
 #BEQUEATH CONFIG
(GLOBAL_DBNAME=salesdb.mycompany)
(SID_NAME=sid1)
(ORACLE_HOME=/private/app/oracle/product/8.0.3)
In your case SID_LIST_LISTENER part is missing.
In this part you have to set SID_NAME and ORACLE_HOME value of new 11g home.
Hope this will help you.

Rajinder

Another ORA-12541:TNS: No Listener

I have Windows Vista
I install Oracle 10g Enterprise edition on my laptop, then I install the DevSuite 10g and 4 days later i cant connect to TOAD or SQLplus I got the error
ORA-12541:TNS: No Listener
I have 2 folders on my C:// Drive
1.- C:\DevSuiteHome_1\NETWORK\ADMIN\ tnsnames
2.- C:\oracle\product\10.2.0\db_1\network\ADMIN\ Listener + tnsnames.
Can anyone help? I ran already the command:
lsnrctl start
And I got the following message:
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
Can someone help?

KEY_OraDb10g_home1/ORACLE_HOME -- Value:
C:\oracle\product\10.2.0\db_1This path needs to be first (or at least before any other oracle stuff) in the PATH setting.
>
I think Dev Suite have its own database but I´mNope. Not in the Dev Suite home.
trying to connect to the database called ORCL which I
setup with the Enterprise edition 10g .So, is the listener started now?
What do you get from lsnrctl stat?

Cannot config EM from dbca with ORA-12541: TNS:no listener

Hi all,
I am having a strange issue with Oracle Database. I have "Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production" running on a windows 7 system. Everything seems working: I can connect and do SQL operations. But my EM is not running. I need to do a re-config by running dbca. I choose to "configure database options" etc for the existing database, roughly at the 67%, it stopped. In log, I see the following exceptions:
Jul 7, 2012 11:12:49 PM oracle.sysman.emcp.ParamsManager checkListenerStatusForDBControl

oracle.sysman.emcp.exception.EMConfigException: Listener is not up or database service is not registered with it. Start the Listener and register database service and run EM Configuration Assistant again .
However, my listener seems working (otherwise, my sqlplus connections wouldn't work, correct?). Please see the attached information. Can anyone please tell me what I am doing wrong here and how to fix it? Thank you all very much!

Can you please tell me what options I need to run emca? My current database is accessible and seems running fine except this EM issue.
dbca can also "configure database options" existing DB's, at least I should not get that error in "C:\oracle\cfgtoollogs\dbca\orcl\emConfig.log" that says

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

ORA-12541: TNS:no listener, (error, in oracle 11g for window 7, 64 bit)
