Connecting 11.1.0.7 client to 9.2.0.6 database gives TNS-12547 lost contact

I just installed 11.1.0.7 client on win 2003 server and tried to connect to 9.2.0.6 database but both tnsping and sqlplus is giving 'TNS-12547: TNS:lost contact' error
Please note that the same client 11.1.0.7 is connecting to database 9.2.0.8 and higher i.e 10.2.0.3 and 10.2.0.4.
Please advice as why 11.1.0.7 client is not connecting to 9.2.0.6 database and giving 'TNS-12547: TNS:lost contact' error.
Thanks in advance.

TNS-12547 lost contact - listener log has TNS-12516??

OS: Win98
DB: Personal Oracle8i 8.1.6
Attempting to make connection from JDBC and eventually found out even TNSPING has problems. I have a listener configured on port 1521, using 127.0.0.1 as the host (I'm doing development on same machine).
I do lsnrctl start LISTENER, but afterwards a lsnrctl status LISTENER returns nothing. Not sure if it only replies if there is a problem. Anyway, it seems like the listener is running, otherwise I'd get a different error, like no listener.
I can't find docs on TNS-12516, and the explanation of 12547 isn't very helpful. The full error text in the listener.log is as follows:
22-JUN-2001 16:05:24 * handoff * giop * 12516
TNS-12516: TNS:listener could not find available handler with matching protocol stack.
I can provide more info if needed.

I also have the same problem. It doesn't seem to happen regularly but off and on. When this database state occurs, I can't even shutdown the database. It appears to hang due to an unknown cause. When I check my listener log, I see that the error messages I was getting were the TNS-12516 errors. The really odd thing is that some of my Perl DBI and PHP programs were still going through without a problem while my sql*plus and discoverer connections were dying with the TNS-12516 error. If anyone has ANY ideas at all, please respond.

TNS-12574 TNS lost contact

We use Central and Regional database, between them we create dblinks. WE use TNSPING to check the connectivity, from Central it works but from regional we get a message TNS-12574 TNS lost contact.
We use Brodband, DDN and VSAT communications. Only from sites, which are used VSAT communications we get a problem. Is there any possibilities to make a connection.

Starting TNS Listener gives "Linux Error: 32: Broken pipe"
by Jeff Hunter, Sr. Database Administrator
You have successfully install Oracle on Linux, installed and configured your application and everything is working fine. You get a call several months later from an angry user saying that he cannot login to the application. The error message indicates a problem connecting to the Oracle database. After noticing the Oracle TNS listener is not running, you attempt to start it and get the following stack trace error:
% lsnrctl start

TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
Linux Error: 32: Broken pipe
You then check with the SYS admin to only find out that nothing has changed with any of the network settings!
This is one of those troubleshooting issues that can take several hours to track done. But as it turns out, the most common reason for this stack trace when attempting to start the listener is the log file for the listener ($ORACLE_HOME/network/log/listener.log) has reached its 2GB file size limit on Linux. To alleviate the problem, simply archive or delete the file and restart the listener.

Intermittent TNS-12547: TNS:lost contact

10.2.0.1 installation problem on redhat 4 (ORA-12547: TNS:lost contact)

Hi,
I tried to install Oracle 10.2.0.1 on a RedHat 4 box. Both, Oracle and RedHat are 64 bit versions. The installation was fine but the database creation (with dbca) could not create the database because of this error: ORA-12547: TNS:lost contact

If you execute "uname -mpi" and output value is x86_64 then you didn't install all required packages.

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.

ORA-12547 tns lost contact while creating 11gr2 database using dbca

Hi All,
I am installing oracle 11gr2 rac on centos 4. Grid infrastrucure and oracle home is successfully installed.
When i try to create database using dbca during that time i am getting an error that PRCR-1079: Failed to start resource ora.racdb.db
ORA-12547: TNS lost contact.
when i check the database on node 1, Its running fine.
However its giving me an error on the second node.
on Node 1

Please help me on this.
Your assistance in this regards is much appreciated.
Thanks in advance.

Do you have a support.oracle.com User Account?
If yes search there for TNS-12547 and you will get a huge list of possible root causes.
Just to name a few (which you can check - also compare with your first node):
Permission oracle executable
Kernel Parameter
Environment variables
etc.etc.

TNS: lost contact error consuming https web services

Hi,
I'm trying this piece of pl/sql code and I'm getting TNS: lost contact error while trying to retrieve soap response. What could be wrong? I'm using oracle 10.2.0.1.0 database. Thanks in advance.
declare
envio varchar2(32767);
peticion UTL_HTTP.req;
respuesta UTL_HTTP.resp;
cadena varchar2(32767);
begin
envio := 'xxx'; -- soap request
Utl_Http.Set_Response_Error_Check ( enable => true );
Utl_Http.Set_Detailed_Excp_Support ( enable => true );
utl_http.set_wallet('file:/oracle/wallets','xxx');
peticion := UTL_HTTP.begin_request ('https://xxx','POST','HTTP/1.1');
UTL_HTTP.set_header(peticion, 'Content-Type', 'text/xml');
UTL_HTTP.set_header(peticion, 'Content-Length', LENGTH(envio));
UTL_HTTP.set_header(peticion, 'SOAPAction','');
UTL_HTTP.write_text(peticion,envio);
respuesta := UTL_HTTP.get_response(peticion);
UTL_HTTP.read_text(respuesta, envio);
UTL_HTTP.end_response(respuesta);
dbms_output.put_line(envio);
exception
when Utl_Http.Request_Failed then
Dbms_Output.Put_Line ( 'Request_Failed: ' || Utl_Http.Get_Detailed_Sqlerrm );
when Utl_Http.Http_Server_Error then
Dbms_Output.Put_Line ( 'Http_Server_Error: ' || Utl_Http.Get_Detailed_Sqlerrm );
when Utl_Http.Http_Client_Error then
Dbms_Output.Put_Line ( 'Http_Client_Error: ' || Utl_Http.Get_Detailed_Sqlerrm );
when others then
Dbms_Output.Put_Line ('Otros: ' || SQLERRM);
end;

The problem is a database bug:
Bug 5575771 UTL_HTTP cannot handle https connections without a content-length
If UTL_HTTP is used to retrieve an HTTPS response with no content-length, it
throws an ORA-12547 on the final read (if the final read is shorter than the
buffer supplied).
Workaround:
Include a Content-Length section on all responses.
(This may not be possible since some responses may not
be under your control)

Srvctl start database -d dbname error tns lost contact

hi,
i am facing error while starting the databse by using srvctl in single node database.
srvctl status database -d <dbname> is working fine and it is giving output. i am able to start the database manually too.
srvctl start database -d <dbname>
PRCR-1133 : Failed to stop database <dbname> and its running services
PRCR-1132 : Failed to stop resources using a filter
ORA-12547: TNS:lost contact
any advice.
regards

may i know what you have done before....srvctl start...etc...
do you have done any changes?
post your oracle version and OS....
please find below notes from metalink..it may helpful to you....
This could be many things but a popular issue is when you have a separate ASM Home and the listener is running out of this home (it was the first home installed). Srvctl needs a TNS_ADMIN alias to the network/admin directory in this home instead of using the default ORACLE_HOME/network/admin for the database you are trying to start. For srvctl to work you must
srvctl setenv nodeapps -n node -T TNS_ADMIN=full path
on each node in the cluster.
You cannot rely on a TNS_ADMIN environment variable.
See Note 420977.1
Another cause is non-existent spfile, see Note 732683.1

Error message "ORA-12547: TNS:lost contact" during dbca

Background info: I am building a new test 11.2.0.3 RAC cluster running on IBM pSeries hardware with AIX 6.1 OS level. I need to practice building a cluster and then adding a new node later. Because of limited hardware availability, my inital cluster will have 1 node and I will add the additional node later.
I installed Grid Infrastructure successfully. GI and ASM are online and appear to be working normally. Today I installed the 11.2.0.3 database software. I am now trying to create a test database using DBCA. After entering all of the database information (SID information, where db files should reside, memory sizing, etc.) the database creation begins, then immediately issues the error message "ORA-12547: TNS:lost contact".
I have searched MOS (Metalink) and also reviewed a few sites using Google. All of the information indicates this problem occurs most often when trying to log into an existing database using sqlplus. I haven't found anything related to this error message during database creation.
Does anyone have advice on how to troubleshoot where the problem is coming from? Can you point me to some documentation that would help with this issue?
Any and all help is appreciated. Thank you!

Srini,
I was verifying that I understood your request. The last install log relates to the Oracle db software installation and was created by OUI. The DBCA utility has not created any actual install logs. DBCA issues the error less than 10 seconds after I choose the "Finish" button to begin the database creation process. I also reviewed 4 notes on MOS and unfortunately they do not seem to apply. The permissions settings appear correct on all directories for both the database software owner and the grid infrastructure owner as well.
Here are the last 200 lines from the OUI install log. Thank you again for all of your help!

DBCA Producing ORA 12547 TNS lost contact when I try to create a database

Hi all!
I just installed Oracle 11GR2 (only software not creating a database) on Oracle Linux 6.4 64 Bit via Oracle VM VirtualBox. I created a new Listener to create a database. It looks working. But when I try to create a new database with dcba; I had an ORA-12547 TNS lost contact after I had specified all options for creating the database. I'm too new to get what's going on here. Already, the Oracle Software has occured a few errors while the installation. But the software has been installed successfully at the end. Maybe I went wrong from the beginning. What should I do about managing that ORA error? Can anybody suggest me something?
Btw I have installed the all installations with information on this link: ORACLE-BASE - Oracle Database 11g Release 2 (11.2) Installation On Oracle Linux 6
If we consider that I did nothing after those installation, what should the next step be to create a database successfully?
