TNS-12502:

Dear all,
I am getting this error after every 5 minutes.
TNS-12502: TNS:listener received no CONNECT_DATA from client
I have checked the tnsnames.ora file and could not find anything wrong in it. The fact is that this error occurs only on Rac 1 and not on Rac 2.
So, I do not understand why is it so. Please help.
Thanks
SL

oerr ora 12502
12502, 00000, "TNS:listener received no CONNECT_DATA from client"
// *Cause: No CONNECT_DATA was passed to the listener.
// *Action: Check that the service name resolved from TNSNAMES.ORA has
// the CONNECT_DATA component of the connect descriptor.
Where are you getting this error?? Means in alert.log or in a connected session??

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

Listener overloaded or High load .?..ORA-12535: TNS:operation timed out

We have an OLTP db server with oracle 11g(11.1.0.7) installed on Linux 64bit OS.
Client : Dotnet application running on win2003 server
oracle client version on webServer 9.2.0.4
Work load on system is
Avg Executions Per Sec 1273.35
Avg Executions Per Txn 42.1
Avg Response Time Per Txn (secs) .13
Avg User Transaction Per Sec 30.4
Avg Concurrent Sessions on server 350 processes 600
memory_target 13gb
we are experiencing "ORA-12535: TNS:operation timed out" while users access the application from webserver.per day around 200 errors.
To get rid of the above error we set SQLNET.INBOUND_CONNECT_TIMEOUT=0 in server side sqlnet.ora and
in Listener.ora inbound_connect_timeout=120 but of no use, even we observed for few days with inbound_connect_timeout=0.
There is Only one listener configured on server.
The similar set up with lesser workload working fine without any errors.
Please let me know your thoughts....

'ORA-12571: TNS:packet writer failure' error while calling procedure from VC++

hi all,
i am writing stored procedures and calling these from vc++. I have one stored procedure in that all
in and out perameters are numeric. When i am calling these procedure i am able to get the values properly. But in another procedure one in perameter is varchar and one out perameter is varchar. When i am calling these procedure from vc++ the error i am getting is "ORA-12571: TNS:packet writer failure". I test my vc++ code on different computers but its giving the same errors. I think ora-12571 error is when i can't communicate with oracle. But other stored procedures(in and out perameters are numbers) and sql statements are running properly. Only these stored procedure which has in and out perameters as varchar is giving me the above said problem. My out perameter in this procedure strtax is of type varchar and the length 100. Is it the problem. Please suggest me how to over come this problem.
thanks in advance,
with regards
vali.

Hi
We recently changed our load balancer to a new load balancer. we get this error only after the load balancer change.
When the error occurs, I could see ORA-12571 error message only in the application error log. The listener.log has only the following message about TNS 12502. It does not have any message about ORA -12571.

Hi,
Thanks for your reply, but your assumption is incorrect that I did not read the error message in the documentation. I read it many times, but could not correlate it with any wrongdoing.
solaris64:102b$ oerr TNS 12533
12533, 00000, "TNS:illegal ADDRESS parameters"
// *Cause: An illegal set of protocol adapter parameters was specified. In
// some cases, this error is returned when a connection cannot be made to the
// protocol transport.
// *Action: Verify that the destination can be reached using the specified
// protocol. Check the parameters within the ADDRESS section of
// TNSNAMES.ORA. Legal ADDRESS parameter formats may be found in the
// Oracle operating system specific documentation for your platform.
// Protocols that resolve names at the transport layer (such as DECnet object
// names) are vulnerable to this error if not properly configured or names are
// misspelled.
The above says that, illegal set of protocol adapters was specified...., I am using 'Local Naming (tnsnames.ora)' connection method and using TCP/IP protocol.
Following are the tnsnames.ora content
solaris64:102b$ cat tnsnames.ora
oeora11g1 =
(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = vm-oedsdev1)(PORT = 1521))

View logfile or view output hangs in 3 node environment

Hi All,
Briefing the environment:
Database -- ERPDB001
Conc + admin -- APPS001
Forms + web -- APPS002
Some times when we try to see view log or view output after running the Concurrent requests. The system seems like hanging and it will display following error after. If you check in the next minute, it will show the output/logfile. looks like a strange behavior
"An error occurred while attempting to establish an Application File Server connection with the node APPS001. There may be a network configuration problem, or the TNS listener on node APPS001 may not be running, Please contact your system administrator."
Is this the Oracle Apps issue or the network issue between two node.
Regards
Vasu

We found not much errors.
One time the error is
"05-JUL-2008 11:38:47 * 12502

But I used to get above Original error (Core issue) lot of times in the Application.
Even users are complaining about this.
Thanks and Regards

Exception occurs only the first time

The server listens on a port to which client connects in applet mode. Every time client connects to server for the first time (i.e. after a fresh server installation), the client pops an exception:
java.io.InvalidClassException: javax.swing.ImageIcon$AccessibleImageIcon; local class incompatible: stream classdesc serialVersionUID = -3994512798706967451, local class serialVersionUID = -1903458698681874148.Subsequent client connects to server does not pop this exception. i.e. This occurs only for the first time.
Through posts in forum, I thought that this could be due to swing serialization incompatibility across version.(But in this application both server and client are on the same m/c having a single JRE and JDK, both are of version 1.4.2 )
But I am not able to reason out why the exception occurs only for the first time and then disappers in subsequent connects. ( despite clearing javaws cache and Browser cache and restarting server ... and it works on RMI mode).
What could be the reason ?

Hi

Hello, Kirill
Thanks for your reply
I checked my server:
The directory exists a file called cwallet.sso is available

The user the oracle software is running under has the correct privileges to access the directory and wallet
- It is ok :)
Can you give an example about "*Implementing TCPS authentication*" ?

Wrong Listener setting in 11.2.0.2 Grid with 11.2.0.2 ONE NODE(win 2008 R2)

Hello,
the listener on the second node doesn't use its endpoint-Entries and doesn't register the database or shows the running ASM-Instanz. No connection is possible on that node.
In Log of Listeners always:
TNS-12502: TNS:listener received no CONNECT_DATA from client
I installed RAC one Node on 2 Servers, first installed and configured grid for both nodes with SCAN. After it I installed the rdbms and created a ONE NODE Database. The grid infrastructure is running nicely and even the swich of the instanz/database to the second node is working.
BUT: on the second node the listener doesn't know the instance. Nor does ist know its asm-Instance. Registration (Alter system register) even doesnt't work.
In 11.2.0.2 the lsiteners are starteet from grid-home before database creation.
On the 1. node everthing is fine, as long as I don't switchover/failover.
On the second server there has been a second listener from RDBMS_HOME created by ? . I stopped it. Th Listener from GRID_HOME ist configured the same way as node 1, but doesn't uses its endpoint-Entries and doesn't register the database or shows the running ASM-Instanz.

I think, I have problems with the listener.ora and the environment settings, tha lsnrctl uses.
When i change listener settings, I get the message:
Failed to open service <OracleOraDb11g_home1TNSListenerLISTENER_DG> - this is the wron HOME!
I don't find an entry in the registry wher I can change listener-Settings.
Whe I try to change the settings (add entries like SID_LIST_LISTENER for a dataguard Konfiguration)on node 1, it behave like node 2: no more services/sid and endpoints.

Hello folks,
I found the bugs (2 independent annotations) and settings we need!
1. Aus: http://download.oracle.com/docs/cd/E11882_01/relnotes.112/e16777.pdf 5.3.9 (write name and public IP in etc\hosts)
2. http://download.oracle.com/docs/cd/E11882_01/relnotes.112/e16777/toc.htm#CJAHIGJE
I changed the wrong entry in HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\OracleMTSRecoveryService\Protid_0 and rebooted the server.
Suddenly the listener knows its IPs and its servces.
Take care about yout local_listener setting in the instance: show parameter local_listener. This IP/name must be reachable. Sometimes I have had instance_2 running on node_1 with the vip_ip of 2 => this doesn not work.
alter system set local_listener='(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))' scope=both sid='*';
I am still not sure, if this values changes to (ADDRESS=(PROTOCOL=TCP)(HOST=+host+-vip)(PORT=1521)).
Check the IPS, that the listener ist running on: lsrnctl status

ERROR: Install cannot verify the oracle 10g Database

I just completed installation of the SES 10.1.8.2 version and am now trying to apply the 10.1.8.4 Service Pack. After the OUI screen asks for my sys password, I click on Next and receive a popup error message that reads,
Install cannot verify the oracle 10g Database. Please ensure that the database and its listener are running and please verify that the information you entered is correct.
The installer log file (installActions2010-04-15_08-56-19PM.log) shows this:

Error:*** Alert: Install cannot verify the Oracle10g Database. Please ensure that the database and its listener are running and please verify that the information you entered is correct. ***

===
I've verified that I can login as EQSYS using sqlplus. Also tested that I can login as sys, too. I've also tested the login using the Admin console and that is fine, too.
Any ideas on what is causing this or how to fix it is most welcome as I've not encountered this error before when installing SES or a service pack. I've even tried the OUI for Service pack 10.1.8.3 but also get the same error.
I've checked the listener.ora and tnsnames and they are OK. I've checked and the listener is running and so is the DB.
Right now, I have the Oracle SES instance up and running at 10.1.8.2 but need to upgrade this to the same level as the other SES search nodes.
Edited by: user8655787 on Apr 15, 2010 2:18 PM
My listener.log file is showing this message each time, I run the OUI and enter the sys password and click "Next"
15-APR-2010 23:17:05 * 12502
TNS-12502: TNS:listener received no CONNECT_DATA from client

A couple of other things that I have tried but have had no affect. I'm still getting the same error:
1. Tried recreating the orapwd file
orapwd file=orapwprdses01 password=prdses01
And make sure that the pfile or spfile has:
remote_login_passwordfile='EXCLUSIVE'
another OTN posting said to try this:
1. Go to directory $ORACLE_HOME/network/admin
2. Modify sqlnet.ora file with following parameter:
tcp.validnode_checking = no
3. If you don't want to disable this, you can put the machine names as follows:
tcp.invited_nodes=(machine1, machine2)
3. Bounce the listener.
.... but, I'm still getting the same error when trying to run the .runInstaller OUI for the service pack for 10.1.8.4.

Error from log, after rebootDatabase Manager not working

Ok, lets try this again :- )
I got Ubuntu 8.04, 32bit installed on a DL360 G3, I figured that I can learn how Oracle works, I don't want the Express Version, I need to learn what we will be using at work and not a limited edition.
After I re-boot the server I can't access what worked before, the Management URL:

so I type:

it lists port 1521 ? is that a different service, what is that ?
I tried
https://dragonfly.mydomain.com:1521/em ( I tried the direct ip address too )
error from browser is:

Interrupted, WTF ?
so I do the next logical step and look inside the log file, results are a repeating problem, same repeating entry:

Some Help, what do these errors mean ? are they the root of my problem ?
I need to get this problem, fixed!! it's starting to bug me.

I stopped reading here: "I got Ubuntu 8.04"
Oracle is supported on many different flavors and versions of Linux: This isn't one of them.
If the point is to learn Oracle then learn Oracle in a fully supported configuration.
Now, instead of learning Oracle, you are leaning what happens when people ignore Oracle's advice and go off making a mess of things on their own.
If you use a supported configuration you can just follow the docs and it installs properly.
If the goal is to become an Ubuntu expert keep following the path you are on. If the point is to learn Oracle I'd suggest a course correction.

Cannot start oracle name server

When I try and start my name server service I get the following error in my listener.log file:

The name server will not start and if I try and execute the Names.exe I get the error:
