ORA-12539: TNS:buffer over- or under-flow

Hello,
Our SIT env is 10.2.0.4 RAC in AIX 5.3 (OPatch version: 10.2.0.4.7)
In SIT we’re getting this same error message (but not in DEV or UAT, same version db, but single instance).
2/22/2011 9:32:44 PM: Oracle.DataAccess.Client.OracleException ORA-12539: TNS:buffer over- or under-flow
I saw metalink has reported this as a bug:
Client Connections Intermittently Fail With ORA-12539 Error in RAC Environment [ID 602879.1]
I saw 10.2.0.5 patch can fix this, is there any better way to work around?
thanks

the trace for 10g client did not give the error messages similar to mentioned in the bug.
i guess 10g client is not able to interpret scan.Hi,
It is highly recommended you go to Oracle Client 11.2 or Open a SR.
The Oracle White Paper about SCAN said:
DNS using a round-robin algorithm on its own does not ensure failover of connections However, the Oracle Client typically handles this. It is therefore recommended that the minimum version of the client used is the Oracle Database 11g Release 2 client.
If using a pre-11g Release 2 client (Oracle Database 11g Release or Oracle Database 10g Release 2, or older) you will not fully benefit from the advantages of SCAN.
Reason: The Oracle Client will not be able to handle a set of three IPs returned by the DNS for SCAN. Hence, it will try to connect to only the first address returned in the list and
will more or less ignore the others. If the SCAN Listener listening on this specific IP is not available or the IP itself is not available, the connection will fail. In order to ensure load balancing and connection failover with pre-11g Release 2 clients, you will need to change the TNSNAMES.ora of the client so that it would use 3 address lines, where each address line resolves to one of the SCAN VIPs.

ORA-12154: TNS:could not ... for imported pl-sql function in Process Flow

Hi
I included in a process flow a PL-SQL function as user defined transformation.
This PL-SQL function resides in my source database, from where I imported it in OWB.
When I am trying the run the Process Flow (from control center manager) I get the following message upon executing that function.
ORA-12154: TNS:could not resolve the connect identifier specified
When I don't include that function my process flow works. Mappings in my process flow read from the same source database as where the function is.
So I don't think it is caused by a problem with tnsnames.ora..
Thanks in advance for anybodies help.
Hans

Hi Oleg,
Thanks for your reply. Indeed I didn't create a runtime repository.
However don't like to do that to for the source DB.
I wonder if I can get around that by executing a SQLplus script instead.
I tried this but my script does never complete when it is started from the process flow. If I run it in SQLplus it runs fine and completes instantly.
My script does:
update 1 column in one record of a table.
commit;
exit;
What do you think?
Thanks,
Hans

ORA-12560: TNS:protocol adapter error while running Oracle Form 10g over IE

Hi,
I am getting the following error message while running my form over Internet Explorer. What could be the error and the solution.
ORA-12560: TNS:protocol adapter error
I am using the same user id/password that i used to create the database.
Plz help.
thanks,
RV

unless you defined the TWO_TASK in your environment, you might need to provide it during the login. The typical Forms login screen has 3 fields, username/password and TWO_TASK , which is the alias used for the database server in the tnsnames.ora file on your end. If you are using iAS forms, then a proper RAD (Resource Access Descriptor) needs to be created by the DBA or whoever manages the iAS server. This is only if SSO is utilized, if not, then you need to provide TWO_TASK as well.
Hope this proves useful

Hi,
1) Check the tnsnames.ora file you are using, verify that it is accessible.
Eg: On Unix:
- Check if you have a $HOME/.tnsnames.ora file - This will be
used in addition to 'tnsnames.ora'.
- Check TNS_ADMIN is set in your environment.
- There is a readable tnsnames.ora file in $TNS_ADMIN
2) Ensure that the tnsnames.ora file contains a line of the form
'alias=(...)' for the alias you are specifying.
Aliases are NOT case sensitive.
3) Make sure that there are no mismatched parentheses in the
tnsnames.ora file.
     4) Even if TNS_ADMIN is set SQL*Net looks in other locations for
     configuration files. Check the default directories for old (or bad)
     copies of TNS_NAMES.ORA. Eg: /etc, /var/opt/oracle,
     $ORACLE_HOME/network/admin
5) Check the default domain name being used, and the path used to
locate aliases, in the SQLNET.ORA file.
The default domain is specified in the NAMES.DEFAULT_DOMAIN
parameter - this is appended to the alias specified in the
connect string if there is no domain given.
Eg: If NAMES.DEFAULT_DOMAIN=mydom.uk
and a connect to "scott/tiger@mydb" is requested
SQL*Net will look for the alias "mydb.mydom.uk"
If NAMES.DIRECTORY_PATH is also specified this determines where
SQL*Net looks for the alias expansion.
6) If none of these show an error enable client side tracing
at level 16 and see what has been written to the client trace
file. There list of aliases in the trace file under the heading
'TNS.NAMES.ORA TABLE HAS THE FOLLOWING CONTENTS'.
7) If ORA-12154 is returned when selecting over a database link from a
client check that the alias in the link can be resolved in the
tnsnames.ora file ON THE SERVER.
8) If you are connecting from a login dialog box, verify that you are
not placing an "@" symbol before your connect net service name.
9) When going from Windows to Linux/Unix platforms,
you can see <carriage return> <new line> characters at the
end of each line instead of <new line> <new line>. Be sure you
use ascii mode when ftp'ing this between Windows and Linux/Unix.

Repeated 'ORA-12547: TNS: lost contact' messages after installing Oracle 10

Hi,
I installed Oracle 10g on Redhat ES 3, and the install went well, but when I try and interact with the server I get the message:
ORA-12547: TNS: lost contact
For example, if I use the Database Configuration Assistant to attempt to create a database, I will see the above message when it begins the database creation process, or if I try to interact with the Oracle server using sqlplus I will see the above message after each command entered.
I had recently tried to install Oracle 8.1.7 on the same box, but abandoned that after deciding that the effort required to link Oracle 8 on RHES3 just wasn't worth it.
I have been told that my previous partial installation of Oracle 8 may be the cause of the problem, and have been advised to uninstall Oracle 8, uninstall Oracle 10g, and reinstall Oracle 10g. I find it hard to believe that it would require such an action to solve this problem. Are there any configuration changes I can make to resolve it?
My problem sounds like it may be similar problem to a recent posting by Hugo Ferrer - but my Spanish isn't good enough to fully understand Hugo's problem. Anyways, I am new to Oracle, so thanks for any help with this problem.
Colm.

My last message asking for a grater degree of specificity was not overly specific, hence I am posting the kernel parms that I have set with the hopes that you will spot one that I set improperly or one that I neglected to set.

ping abc
ping xyz
But when the same thing i am trying to do from xyz.localdomain i am able to ping the db running on xyz.localdomain. but getting the above mentioned error duringg pinging of abc database located on abc.localdomain server

Hi,
no, you got it wrong:
Oracle uses network services which are a logical representation of the database to resolve network requests.
in your ntsnames.ora file you have the following:
network_alias = my_alias -- here you can write anything you just need to resolve it correctly
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(host=hostname or IP)
(port=listener adapter port)
) -- this a complete socket information of the listener adapter!!
(CONNECT_DATA=
(SERVICE=your_service) -- this is what you tell the listener about the service you want to connect to. It is defined in the instance with the paramter service_names
In general it is network aliasses which are resolved with connect descriptor in the tnsnames.ora.
A connect decriptor consists of the address part + the connect_data part.
The address part is used to reach the listener.
The connect_data part is the information you hand over to the listener.
So the listener must know the service name.
The listener can either know this from the instance itself. When an Oracle instance is started it tries to registrer itself with a listener which listens on port 1521 for the protocol TCP.
The instance tell this listener two paramater values: INSTANCE_NAME and SERVICE_NAMES. Then the listener knows the instance and which services are defined. It is just a reprentation of the database to the listener.
If the listerner knows the service requested with a connect, it can establish a connection to a service handler. This could be a dedicated server process or a dispatcher.
Another mehtod to let the listener know the service requested is so called static regustration of the instance. This is made with an SID LIST in the listener.ora file.
Then the listener knows SID for the instance plus ORACLE_HOME and can find the executable to start a server process for a connect request.
Hope it helps a little-.
=;-)
If you have further questions pls do not hesitate to ask. O.K.?

ORA-12154: TNS:could not resolve the connect identifier specified [10g XE]

Greetings
There are many topics on this issue over the internet but None of them addresses this issue properly, so I couldn't find a solution to the problem.
I installed: Oracle Database 10g Express Edition
After the installation was done, I opened SQL Command Line
and I used the command "connect" to login
I enter the username
Then I entered the password
After a couple of seconds I got the following ERROR message:
ORA-12154: TNS:could not resolve the connect identifier specified
Screenshot of the error:
http://i35.tinypic.com/14o26g7.png
I installed this version of Oracle on both Windows XP 32 bit and Windows 7 32 bit and I get the same error message when it tries to connect.
Why doesn't Oracle work right after the installation?
Are there any further steps that need to be done in order to make this work? If so I would really appreciate any step by step help, I've been stuck trying to find a solution for days.

I wento to CMD, then I entered sqlplus / as sysdba and that just opened the SQL*Plus program in CMD (SQL>)
But nevertheless I still need to login with a user name and password which and I tried and I got the same error message.

Get into SQL*Plus with the command I gave you, now type this:
alter user <theusernameyouwant> identified by abc123;followed by (still in SQL*Plus):
connectafter you type "connect", SQL*Plus will ask you for a user name and password. Use the same user name and password you used in the alter command.

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,

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 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-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.
TNS-12502: TNS:listener received no CONNECT_DATA from client

Report connection error ORA-12203 : TNS : unable to connect to destination

hi
when in open report and go to query builder then show me this error
REP-0501 : Unable to connect to the specified database.
ORA-12203 : TNS : unable to connect to destination
how i connect report and form with oracle8i which two file in copy into developer folder
please give he solution
thanking your

$ oerr ora 12203
12203, 00000, "TNS:unable to connect to destination"
// *Cause: Invalid address specified or destination is not listening.
// This error can also occur because of underlying network or network
// transport problems.
// *Action: Verify that the net service name you entered was correct.
// Verify that the ADDRESS portion of the connect descriptor which
// corresponds to the net service name is correct. Ensure that the
// destination process (for example the listener) is running at the
// remote node.
$In Developer Home check that TNS alias in tnsnames.ora has no errors. Are you able to connect from Sql*Plus from Developer Home, using same alias ?
Also check that the listener is running on DB machine.
how i connect report and form with oracle8i which two file in copy into developer folder What does it mean exactly ?
