Listener errors in logs TNS-001184 TNS-12502

Oracle Enterprise Edition 10.2.0.3
HP-UX
2 Node RAC
Hi
I have seen repetitive errors in listener log file of one of our databases.
The errors are like this,
07-DEC-2010 12:35:27 * service_register * EXS1 * 1184
TNS-01184: Listener rejected registration or update of service handler "DEDICATED"
TNS-01185: Registration attempted from a remote node
08-DEC-2010 12:35:27 * service_died * EXS1 * 12537
08-DEC-2010 12:35:27 * service_update * EXS1 * 0
There are also errors like the following,
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
TNS-12502: TNS:listener received no CONNECT_DATA from client
I referred this oracle metalink note, ID 275058.1 and it says this is because LOCAL_LISTENER and REMOTE_LISTENER are not configured properly, But I see errors like this being frequent (every minute) yesterday and only once today.
Our Application team complains about problems in performance of various procedures at various time intervals. Can this be the cause of such performance degradation ?

The first error is similar when copy/paste listener.ora to other node (ex. test enviroment) and not modify listener.ora then when you tyr start listener, it connect and register to original node.
If your application team have poor performance, maybe you must trace (tkprof or sqlnet trace) to concrete the problem.
Good luck

MARS - Oracle TNS listener errors

Anyone familiar with this:
[pnadmin]$ pndbusage
Program aborted due to: ORA-12541: TNS:no listener
MARS was fine before the holiday weekend. When I came back, I was looking at the summary page and the graph wasn't being drawn. I SSH'd to MARS and did the above.
While SSH'd to MARS (and my HTTPS session still open) I did a reboot and I still get the same error. Also, now when I HTTPS to MARS I get a login page, but the url is: https://10.6.184.116/logout.jsp
The username/password fields and login button are in the upper left corner of the browser window, not in the middle like normal.
So, now I have two problems. The first being my TNS listener error and the second being that I can't log in. It wants me to log out first...ugh.
Thanks,
Bob

This sounds like a known issue and if memory serves a developer will need to login and do something, so you'll need to open a TAC case.

hi,
Please check the connectivity from server to client.
And also check whether the tnsnames.ora file has the TNS entry of the DB server which you are trying to connect.
Then TNSPING the server with tns name.
If this also doesnt work try commenting all lines in sqlnet.ora file on server.
Check the listener status also on the server.

Connect to Oracle through ODBC - TNS: No Listener Error

Hi All,
I've been trying to chase this problem down for over a month now and I have had no luck. When I try to connect to an Oracle server through MS Access I get the TNS: No Listener error. The kicker is when I go to the odbc data source administrator in windows I am able to connect to the oracle server. My computer is windows 2007 and I have Oracle 11.2 installed. Could anyone assist?
When I type lsnrctl start in the command prompt it says it has been already started.
Here is my tnsnames.ora:
ORMANRPT.WORLD=

here is my listener.ora

I suggest you move, remove, rename, delete or otherwise move the listener.ora file out of the way.
listener.ora is NOT required to start or utilize the listener
open Command Window after doing as directed above then issue the OS commands below
lsnrctl stop
lsnrctl start
lsnrctl status
# now wait 60+ seconds before issuing the next command below
lsnrctl service
COPY the results from all above, then PASTE all results back here.

Hi,
a different point: make sure the (host = ) part of your ADDRESS_LIST is correct, it seems the listener tries to bind to a host/port combination that does not exist. Don't use localhost there or nobody will be able to connect to the database which is probably not what you what.

Martin

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.

[HELP] 10g error TNS-12518: TNS:listener could not hand off client connecti

Hi all,
TNS-12518: TNS:listener could not hand off client connection
(when I do a sqlplus, it hangs for one two minutes, then the error above shows)
My oracle 10g is installed in a windows system. this error only happens when the database is heavily used for some time. After I restarted the Listoner, the connection is ok again. Does anyone has a solution for this? Thanks a lot.
Jason

Monitor your page file usage on Windows system (I assume its a 32 bit machine). When Windows starts to swap Oracle SGA into page file., you encounter TNS errors. Strange but we have observed this.
If you can allocate more free physical memory on the server (by removing unwanted applications from the memory), then you can reduce these errors.
Permanent solution would be to add more physical RAM (with 4GT on 32 bit) or switch to 64 bit architecture.

Typo corrected and added following.
You can set DIRECT_HANDOFF_TTC_LISTENER=OFF in listener.ora and restar the database as temporary solution. Check metalink Doc ID: 233747.1

TNS-12541 TNS: No Listener error HELP!!!

Hello,
We have installed Oracle 8.0.5 on Windows 2000.
Oracle was well installed (no errors) but sometimes we can connect to the database (via SQL+ or by a tnsping on the client), sometimes we cannot and it shows above message (TNS-12541 TNS: No Listener). That is very strange: the listener do really exist and is running. (Service is started). I tried to stop and start manually the listener (tnslnr80) but the 'start' failed (it was too long so I killed the command).
Can someone help us to solve this or to understand what happens?
Thx a lot

I reconfigured the instant client following below link :

and followed your advises as well and i can now connect to database though any user
But unfortunately, i cannot connect as sys user, it gave me below error :

Could you please advise..
Regards,
MohammedIf the client is on the same machine as the database, then you don't have ORACLE_SID set.
More likely the database is on a different server, you have to specify 'sqlplus sys/pswd@dbname'.
And your db will need to be configured to allow remote sysdba authorization, which is not a good idea from a security perspective.

TNS-12224: TNS:no listener - 32-bit Windows Error: 61: Unknown error

Hi,
I have a fresh install of 11.5.10.2 in windwos 2003 and I'm facing the following error in both nodes (1st node database, admin, cms (mcorafinbdcl)----- 2nd node forms and web (mcfinappcl) in 8.0.6 listener:

32-bit Windows Error: 61: Unknown error
I have recreated the listener removing the srvice and doing a lsnrctl80 start APPS_D11i but still not working!
Please help! Thanks

Hi!
The issue I'm facing it is vaery strange and partially fixed:
1-) If you start the listener via script adalnctl.cmd or via command line "lsnrctl80 start APPS_D11i" it fails always.
2-)If you start the apps listener via services, start --> Administrative tools --> Services. It works
I'm connecting via terminal services, I have read somewhere that this could be an issue!
As well and related with this issue, when I run autoconfig (in terminal services using remote desktop connection) it hangs in step:
adsvalsn.cmd --> this command creates the apps listener
And the autoconfig finish with error:
adsvalsn.cmd INSTE8_APPLY -1
Due this adpatch is giving me an error
Thanks

Tns remote listener errors

Hi,
I'm in the process of transferring a single instance to rac, and a bit stuck with the remote_listener parameter. As per the oracle guide I have setup the tnsnames.ora as follows:
$ more tnsnames.ora
LISTENERS_S78LIVE =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = eus3300106-vip)(PORT = 1521))

S78LIVE =

(LOAD_BALANCE = yes)
(CONNECT_DATA =

(FAILOVER_MODE =

(RETRIES = 200)

S78LIVEA =

(CONNECT_DATA =

(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = S78LIVE)
(INSTANCE_NAME = S78LIVEB)
when I tnsping, I get the following error

I can ping the host??
Anybody had the same problem, or is my tnsnames wrong.

TNS no listener error when internet is enabled

Hi
When my internet connection is enabled and if i try to connect to the database, I get the No listener error.
Although I'm able to connect to database when there is no internet I find it hard to run my forms 9i as they run on Internet Explorer and only when there is internet connection.
Please help me in this regard.
Thanks in advance
rishank

I think, that your listener listen to only one address.
Try to edit tnsnames.ora to replace you hostname with local network address.
