LSNRCTL is missing in 9iLite installation; TNS-12541: TNS:no listener

I have installed Oracle9i Lite on Windows XP Professional
(Build 2600). I installed the Mobile Server and then the
development kit, but after all of this, it appears that no
listener has been installed. I cannot even find the
LSNRCTL.exe file anywhere on my hard drives. Maybe it's in a
JAR somewhere in the installation set, but shouldn't this file
have been copied down and installed? The only two services
listed are Oracle Lite Multiuser Service and
OracleOUIHomeClientCache. The error which I receive
consistently through every means of attempting to connect to
the local Oracle instance (such as the sample database) is TNS-
12541: TNS:no listener.
Am I missing something here? I installed the 9i Lite version
because the 8i Personal Edition is not supported on Windows XP.
Thanks in advance!

Good afternoon,
This has boggled me for the past six hours so I'm asking for assistance.
I downloaded "Oracle9i Release 1 (9.0.1) for Microsoft Windows NT/2000/XP (Enterprise/Standard/Personal Edition)" for my own personal use and to get experience installing a database on my PC.
I'm getting the ORA-12541: TNS:no listener error message when I try to connect to my database. I try to find and run the LSNRCTL utility, but it's not present on my machine. I've re-installed 9i 9.0.1 enterprise again and again, the program isn't on my machine. The HTML help file (http://www.csis.gvsu.edu/GeneralInfo/Oracle/network.920/a96580/admintoo.htm#487040) for Oracle Net says the program SHOULD be in oracle/bin but it's not.
Any other ideas? The ones recommended above helped me to research the topic, but still haven't given me a resolution, and I'm at a wall here.
Thank you.
-Brad

TNS-12541: TNS:no listener after 10g DB installation

After installing Oracle 10g DB on my PC (Windows XP), I went to SQLPLUS, but when I connected using system user, it gave me an error:
TNS-12541: TNS:no listener
Then, I tried to check the status of the listener as below.

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.

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.

Hi,
Did you check whether the windows service for listener is up and running? if not please start it, by typing "services.msc" in run window and start the service. Then check whether you have listener.ora file in $ORACLE_HOME/network/admin and also post listener.ora contents.

hi,
first be sure that oracle database service and listener service are started as same OS username and this user was in the list of group oracle dba
second stop all services and delete all listeners using netca and delete all files(listener.ora, tnsnames.ora) from network\admin\ folder
after create new listener using netca and check hostname in listener.ora, if everything is ok create new connection string in tnsnames .ora and then do following commands on cmd and put here result.
lsnrctl stop
lsnrctl start
lsnrctl status

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).

Service "orcl_XPT.us.oracle.com" has 1 instance(s).

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.

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

Oracle 8.1.7: TNS-12541: TNS No Listener

The OracleHOME_SVRTNSListener service is running. The listener.log file correctly states this fact. When I connect from SQL*Plus Worksheet (username@dbname/pw) it do connects me. Connecting from Dev 6i forms is also ok. Accessing from PHP script also works well. However, all of the below cases give this error "TNS-12541: TNS No Listener".
a. Connecting from SQL*Plus.
b. exp/imp utility program. (if i misspell connect string, the error is as expected i.e. TNS protocol adapter error. For correct connect string as defined in TNSNames.ora, the above error appears).
c. Running lsnrctl.exe and giving 'stop' command also gives the same error. However, 'start' says that the aformentioned service is already running and then gives the same error message.
Plz Note:
The last thing I did after which this problem got in was to run Database Configratio Assistant to make script of a 3rd DB on my system (Intel P-IV, Win 2K A server) and then run the generated batch file.
Also note that the newly created DB is working fine and accessable as well i.e. from sql plus worksheet and php scripts
The sqlnet.log file does record the error but tells the same story "error 12541 - TNS No Listener".
There is an interesting situation to tell. I have 8i on another machine as well (call it B). when I configure and connect using B's exp/imp utility or sql*plus or anything to A (the problamatic oracle machine), it works fine i.e.
exp [email protected]
works exactly fine. It connects to mydb on machine A using system account and starts exporting. But Why doesn't this mechanism works on machine A itsself???

Here is the output of few commands (all given on server machine)

ORA-12541: TNS:no listener on my VISTA

Hi guys,
I've installed Oracle 10g on my Windows Vista laptop and it says Successful but upon connecting to Database using TOAD or SQL plus an error ORA-12541: TNS:no listener. What seems to be the problem here. I've search the forums and try all the advices but to no avail.? I run the lsnrctl start / in the command prompt but it seems that lsnrctl command is not recognize as an internal or external command. by the DOS. I also checked the Services to determine if the OracleServices is running but I cant find any Service with Oracle name. Ive reinstalled twice but unfortunately same things happen. Kindly advice.
Thank you
Jay

Sybrand and Zack: Thanks for pointing me to the log. I was able to see that the problem computer had a Windows Computer Name mismatch. And also, its "Microsoft Loopback Adapter" network connection had been disabled. While I could have tried enabling the MLA, I chose to set the "HOST = " value in the listener.log file in the %ORACLE_HOME%\network\ADMIN\ path to match the Windows Computer Name. Once I changed that, I was able to start the Listener.
...and now, I need to address the issue of Vista versions:
If you guys would look up the Microsoft Windows Vista: Compare editions page, you would see that the differences are just frosting on the cake. Things like "Aero Desktop", "Tablet PC Support", "Windows Meeting Space", some backup/restore options and more games (Yeah I really want InkBall and Chess Titans!). Otherwise, Vista is running the same engine under the hood.
I have no clue why Oracle has chosen to certify only a specific Vista version. It appears they have fallen for a Microsoft marketing ploy: give people a choice of levels, and human nature is to always reach for the more expensive one.
A few years ago, when Oracle was proudly bragging about their robustness and the "Write once, Run anywhere" theme, they would have certified their software on all Vista versions. Given Larry's distaste for competition with Microsoft, it would seem like he would have urged Marketing to aim for the leanest Vista version. But then maybe Marketing decided that having software that ran on the cheapest Vista version would look cheap. Or maybe they are looking for ways to cut back on costs -- it is less expensive to say you support Vista and then tell some of the people seeking help that they have the wrong version, rather than spend the time helping them work through the problem.
No matter what Oracle's reason, I still say you guys parroting the same line as Oracle are doing a disservice to people looking for help on the forum.
The answers given so far were perfectly valid, because this is the
answer you will get from Oracle Support. They will not help the OP. Nor
will they help you when your database on Vista Home crashes.Sounds like my mother telling me to put on a coat before I go out to play. "You'll be sorry when you catch a cold!"
Sorry, but Oracle is the LAST place I would go for help. Multiple times, I have presented issues to Oracle, and the person at the other end either could not comprehend the problem, or maintained that what I was seeing was the same as another bug... It is my experience that they go to the greatest lengths possible to maintain that there is nothing wrong at their end. The result is that it is up to me to find a workaround.
Not certified means not certified. It might work, and then it might not
work. You have just been lucky.Right. I work on software day in and day out that has been uncertified by Oracle, but still runs fine -- in production. And on the other side of the coin, have published steps to get software to run on platforms not yet certified by Oracle.
People are providing this answer here, because no one can provide more
support than Oracle Support actually does.Why do you write such stuff? Every time I encounter this Re: Sarcasm and negative comments, it gets me going.
