10.1.3 EA1: ORA-12518, TNS:listener could not hand off client connection

Hi,
Trying to connect to a remote database which worked in 10.1.3 developer preview gives now:
Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
The Connection descriptor used by the client was:
From sqlplus I can connect. I don't have access to the remote database server/configuration. I tried the workarounds specified here
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=139775.1
I deleted
ojdbc14dms.jar ojdbc14.jar
from jdeveloper and copied ojdbc14_g.jar from Oracle 10g release1 (renamed it to ojdbc14.jar). Then it worked.

Hi,
Can you please check the below link from the forum too.

ORA-12518: TNS:listener could not hand off client connection

guys,
i have a problem here with the connection between a client host and a server database, using a new non-default listener LISTENER_BKP_1. The error showed is:
ORA-12518: TNS:listener could not hand off client connection
i had learned about this error here before, and i toke some notes as follows:

this means that it didn't reach the resource limites yet. What i can do to solve the problem ???
another important information is that connecting by the default listener LISTENER instead of the LISTENER_BKP_1 listener, the connection is completed successfully. There's enough SGA memory space too.
Tks,

ORA-12518: TNS:listener could not hand off client connectionDon't do Oracle on Windows, so I'm not sure how the following relates to the Listener dealing with a dedicated server connection request on Linux/Unix.
On Linux/Unix, a dedicated server request means just that - a dedicated process has to be started to service that client. The Listener does it by using the parameters of the configured listener.ora service to execute +$ORACLE_HOME/bin/oracle+. This process then starts up, and the Listener hands off the client connection for this process for servicing.
If there is a failure somewhere on this series of steps fail, the Listener throws the ORA-12518 exception. For example, the +$ORACLE_HOME+ has been incorrectly configured in listener.ora and it fails to execute and startup a dedicated server process.
And this relates to the underlying error you are seeing:
TNS-12518: TNS:listener could not hand off client connection
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directoryI think that the Listener on Windows uses the CreateRemoteThread() Win32 call to start up the server process thread. However, it needs a valid process identifier (of the existing Oracle instance) for this call - and thus needs to first identify the Oracle instance process. Could be that this step uses a ORACLE_HOME reference. And if that directory path is not valid, it is unable to identify the process id of the Oracle instance and thus unable to spawn a dedicated thread to service that client.

ORA-12518: TNS:listener could not hand off client connection (DBD ERROR: OCIServerAttach)

Hi again,
I'm on my enterprise management console and Database Instance and Listener shows the green arrow, but the Agent Connection to Instance shows a red downward arrow and the error:
Status: Failed
Details: ORA-12518: TNS:listener could not hand off client connection (DBD ERROR: OCIServerAttach)
My OraClrAgnt service is up and running (using winxp pro, oracle 11gR2), I'm on my home pc, all my ports are open (my machine's name is "abigail" and it is dmzhost)
Any suggestions to resolve this error?

Sometimes I got ORA-12518 Tns: Listener could not hand off client conenction
adding

Here is my listener.ora.
Where should I add it?
like this????????????????

[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

I've installed Oracle XE 10 on Windows XP. When I browse to the database homepage, I get this in listener.log:

I don't think it is shortage of resources (just rebooted). I put "DIRECT_HANDOFF_TTC_LISTENER=OFF" in listener.ora .. no luck. I removed the listener.ora file altogether ... ditto.
What else could cause this?

TNS:listener could not hand off client connection

while trying to select from dblink I got ORA-12518: TNS:listener could not hand off client connection
What should I do?
here is the listener.ora
SID_LIST_LISTENER =

What is the operating system and database version for remote and local machines.
Are you using dedicated or threaded server on the remoted DB. More information is needed.
output from error message search:-
12518, 00000, "TNS:listener could not hand off client connection"
// *Cause: The process of handing off a client connection to another process
// failed.
// *Action: Turn on listener tracing and re-execute the operation. Verify
// that the listener and database instance are properly configured for
// direct handoff. If problem persists, call Oracle Support.
// *Comment: The problem can be worked around by configuring dispatcher(s)
// to specifically handle the desired presentation(s), and connecting
// directly to the dispatcher, bypassing the listener.

PGA memory Leak issue along with TNS: listener could not hand off client connection

Hi,
We have two Oracle Database instances in a 32 bit Standard Edition Windows OS machine with 3 GB RAM : 1) 1525 MB (SGA+PGA) 2) 515 MB (SGA+PGA)
Recently we upgraded the RAM from 3 GB to 4 GB. Subsequently we upgraded the SGA + PGA of the 2nd instance to 771 MB.
This has resulted into PGA memory leak issue reported in the alert log file and trace file.
Reverting back the SGA+PGA size to 515 MB solved the issue.
Is this issue related to Address Windowing Extension (AWE)?
Is the reason related to Total memory for all the cumulative Oracle instance should be < 2GB.
How to solve this?

There may be something fixed in the patch that gives the error rather than mysterious hangs. I would prefer that, myself. There may be something in the patch that changes how Oracle allocates user, system and program areas.
At some point you spend more trying to limp things along in a growing environment than simply upgrading. 32 bit environments these days is an indicator that management is figuring some false economies. But that's their prerogative.
The PGA can be affected by many things, not least of which is how the application uses it. Much has been written about it, my own experience has been more is used than most people say. But that is probably just my app. Note there are different ways to set it, and a parameter with "target" in it might not be a hard limit. Different execution plans for the same code may use different amounts of memory - there can even be situations where forcing some code to use a sort area instead, or even forcing more operations to disk, can free up more pga for everyone else. It depends. But that's why I look at multi-pass operations in dbconsole.

ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect

Hi Friends,
I have created 10g database for catalog.
I kept the tns entry in some other server. Tnsping is working fine.. I can see the result.

Please help me..
Thanks in advance.

Try on the server where it doesn't work:
sqlplus ismdba/xxxxx@"(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = torora60)(PORT = 1522))) (CONNECT_DATA = (SERVICE_NAME = rman09na)))"
or
tnsping "(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = torora60)(PORT = 1522))) (CONNECT_DATA = (SERVICE_NAME = rman09na)))"
(note the double quotes)
If that works then your tnsnames.ora is incorrect on that server.

ORA-12154: TNS:could not resolve the connect identifier specified
Cause: A connection to a database or other service was requested using a connect identifier, and the connect identifier specified could not be resolved into a connect descriptor using one of the naming methods configured. For example, if the type of connect identifier used was a net service name then the net service name could not be found in a naming method repository, or the repository could not be located or reached.
Action:
- If you are using local naming (TNSNAMES.ORA file):
- Make sure that "TNSNAMES" is listed as one of the values of the NAMES.DIRECTORY_PATH parameter in the Oracle Net profile (SQLNET.ORA)
- Verify that a TNSNAMES.ORA file exists and is in the proper directory and is accessible.
- Check that the net service name used as the connect identifier exists in the TNSNAMES.ORA file.
- Make sure there are no syntax errors anywhere in the TNSNAMES.ORA file. Look for unmatched parentheses or stray characters. Errors in a TNSNAMES.ORA file may make it unusable.
- If you are using directory naming:
- Verify that "LDAP" is listed as one of the values of the NAMES.DIRETORY_PATH parameter in the Oracle Net profile (SQLNET.ORA).
- Verify that the LDAP directory server is up and that it is accessible.
- Verify that the net service name or database name used as the connect identifier is configured in the directory.
- Verify that the default context being used is correct by specifying a fully qualified net service name or a full LDAP DN as the connect identifier
- If you are using easy connect naming:
- Verify that "EZCONNECT" is listed as one of the values of the NAMES.DIRETORY_PATH parameter in the Oracle Net profile (SQLNET.ORA).
- Make sure the host, port and service name specified are correct.
- Try enclosing the connect identifier in quote marks. See the Oracle Net Services Administrators Guide or the Oracle operating system specific guide for more information on naming.

ORA-12516: TNS:listener could not find ... on Windows Server 2003

We are getting "ORA-12516: TNS:listener could not find available handler" while testing asp.net web application.
We have following configuration:
- A 10g database server on Windows Server 2000
- A Web Server running IIS6 on Windows Server 2003
- ODP.Net for 10g client installed on Web Server
we are testing our web app with 75 concurrent users, as far as I can tell we are closing connections in our app and open connection only while retrieving and saving records.
I saw this error very first time when we upgraded our web server to use 10g client. Before that we were using Oracle 9 client and have tested this app with 100 concurrent users without any error.
Does anyone can help or point a resource that can help to resolve this error?
Thanks.

Hi,
You'll likely want to take that up with the networking folks as the error seems to be coming from the Listener.
How many connections does each instance of your app make? If you make the same number of connections via sqlplus for example rather than ODP, do you see the same results? I know creating 60 or sqlplus sessions may not be fun, but it will help determine if this issue is truly somehow related to ODP. It doesnt seem likely it would be, and if ODP can be removed from the picture, it will be that much easier to troubleshoot.
One thing I'd suggest though, is to make sure your app is cleaning up after itself properly to as to use resources efficiently. If you have access to My Oracle Support, see the following note:
Note 730678.1 Oracle Data Provider for .Net Best Practices
Hope it helps,
Greg

Hi...Please help...Getting ORA 12154 TNS Listener could not resolve...

Hi,
I have just loaded Oracle 10g Rel 2 in Win 2003 Enterprise Edition.
But when I try to connect to sqlplus, I am getting ORA -12154 : TNS: Listener could not resolve the connect identified specified.
I have registered the database, the listener and tnsnames have been set correctly.
I have also set the Oracle Home environment variable.
Still getting the error.
Any help will be highly appreciated.
Thanks,

I agree
ORA-12145: (does not exist in the standard manuals)
ORA-12154: TNS:could not resolve the connect identifier specified
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
ORA-12541: TNS:no listener
It is pretty easy to fat-finger these 4 message numbers. As a result, when a person has the actual and complete error message and an error number for a different message, it is usually not a bad idea to use the actual message. (Based on transposing only 3 digits compared to typing over 50 characters correctly.)
In this case the OP has really bollixed things: Subject implies a true 12154, text in the thread is an actual 12514 but mentions 12154.
As a result, there are several potentially correct answers, depending on the interpretation of the question.
- sb92075 gave the correct answer based on the number
- I gave the correct answer based on the message in the thread
- Anurag and Ed gave the correct answer based on 'the question is not formed correctly'
