DRA:12541:TNS Listner Error

HI,
We are using Oracle 9i 64 bit Database Server on Windows 2003 Enterprise 64 bit Itanium Server.After installation while i am running this application we are facing the error that:-"DRA 12541: TNS :No Listner.
And it not connects to the database even on local machine.
Please give the solution to resolve this problem.
Sachin

Could you paste output of the following command ?
sql > lsnrctl status
make sure , you run the given above command on you database server, not on the client.

ORA-12541 TNS no listner

Hi,
When Oracle forms and reports application is accessed through the web, the logon screen is displayed. When users type in the credentials, we get a ORA-12541 TNS no listner error.
Please guide.
I am an apps developer trying to fix this issue.
Thanks

Normally this error means that the listener is not running on the server. Please post the result of
- lsnrctl services (on database server)
- the content of tnsnames.ora and sqlnet.ora (on application server).

porblemYes. There is a very easy process to solve this:
1) open a Windows Explorer, go to the directory (oracle home)\network\admin, copy and paste into the forum the files listener.ora, sqlnet.ora and tnsnames.ora
and
2) open a cmd window, enter command lsnrctl status and ipconfig /all, copy and paste into forum the complete display of this

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

Drop DB control, error: Could not connect to SYS, ORA-12541

Hi All,
I am new to Oracle. I am struggling to solve this problem for 2 days, but still couldn't get it done. I post my problem here and wish every guru in this forum to offer some help. Any suggestions are greatly appreciated.
I have Oracle 10.2.0.3.0 installed on GNU/Linux. There are several instances there. The database, listener, sql/plus all work fine. Yesterday, I installed 10g database control on server. The information showed that dbconsole created successfuly. However, I use the produced url (http:// xxx(hostname):1158/em)in my local machine (Win XP) to connect the databse, and the webpage opened. The information showed that EM couldn't be connected to database, and the status of Listener is unavailable, the inforamtion for agent connect.. is: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
I googled lots of posts both in this forum and internet and tried to make some changes, but the things get worse. It still didn't work. Even i failed to drop the DB control with the command of emca -config dbcontrol db -repos recreate. the error log information in cfgtoollogs/emca is:
Could not connect to SYS/(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=svv.X.XXX.net)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=ORCL3))): ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
I understand it's the problem related to listener, but i have no idea how to verify it. I put the tns.ora and listener.ora here.
tnsnames.ora:

ORCL3 =
(DESCRIPTION =
(ADDRESS_LIST =

(CONNECT_DATA =
(SID = ORCL3)
listener.ora
LISTENER =
(ADDRESS_LIST=
     (ADDRESS=(PROTOCOL=tcp)(HOST=10.3.149.210)(PORT=1521)))
SID_LIST_LISTENER=
(SID_DESC=
(GLOBAL_DBNAME=ORCL2)
(SID_NAME=ORCL2)

(SID_DESC=
(GLOBAL_DBNAME=ORCL3)
(SID_NAME=ORCL3)
(ORACLE_HOME=/opt/app/oracle/product/10.2)
The above is the problem description, any suggestion and help are greatly appreciated.
Thanks,
Kind regards,
Ian

I use the "emca -config dbcontrol db" to config the DB control, but failed. The following is the log information:

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.
This discussion forum is turning more and more into a Q&A forum for redundant answers on redundant questions, asked by people who can not be bothered to use existing resources.

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,

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.

I dont have access of disable the firewall in my clent mechine.I will get it done by network team and post you the status.

Sorry about my english

Hi,
Typically when you get "Message xxxx not found: ..." error messages when trying to start the listener, it means that your ORACLE_HOME is not properly set.
The walkthrough is to set the ORACLE_HOME at envionment level just before using the command, and maybe also as a system environment parameter.C:\>ECHO %ORACLE_HOME%
%ORACLE_HOME%
C:\>SET ORACLE_HOME=C:\NOWHERE!
C:\>ECHO %ORACLE_HOME%

I have also tried various other user id's and passwds:.
scott/[email protected]
oracle/passwd@sid
<snip> ped

i think you want to connect to a databaseServer on the local host.
set the ORACLE_SID variable with the command
export ORACLE_SID=<here_the_name_of your_database>
with bash shell.
then start sqlplus with
sqlplus system
and type the password at the following prompt. default password for system is
manager
better not use the user/password cmdline,
cause other users on this system can see your password in the processList (ps ax).
create a demo user, i found no user scott after installing.
have fun
null

Ora-12541 no listner error
