Intermittent TNS-12547: TNS:lost contact

Does anybody experienced sporadic TNS-12547: TNS:lost contact, especially when loading machine with big INSERT queries? Is this well known and solvable? How may I track down this error? I'm using Oracle 8.0.5.0.0 on a standard RedHat 6.1 distribution.
Many thanks to everybody

I've got the same problem. I'm trying to access the O9i 9.2. Either through TOAD or ODBC, I get an error from TNSLSNR:

Any ideas?

TNS-12547: TNS: Lost Contact

I installed Oracle8i on Windows NT EE edition with SP6a. It
passed the test in Net8 Assistant. But after I installed a
nother package and I tried to test again with: cmd> TNSPING
MAchineName, I got "TNS-12547: TNS: Lost Contact".
Thanks.
Robert

The OraBooks suggest that the package you loaded (or
dependecies) terminated abnormaly while executed (see below).
Suggestion: Debug and/or reload the package if applies.
Make sure that for typical SGA buffer configuration you have at
least 512 RAM and mprocessor at least 600MHz clock and plenty of
disk space.
<<
TNS-12547 TNS:lost contact
Cause: Partner has unexpectedly gone away, usually during
process startup.
Action: Investigate partner application for abnormal
termination. On an Interchange, this can happen if the machine
is overloaded.>>

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.

Hi,
1)ping is working?
2)disable the firewall running on the windows machine,Check firewall at network level is affecting this connection
3)listener is up and running on the EBIZ side and u can connect using the service_name of EBIZ in EBIZ server?then copy the service_name entry form the server tnsnames.ora to the windows machine and try
4)Check at server o/s level are there any restrictions for other machine to get connect,Can u telnet to the server from this machine?

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
LSNRCTL for Linux: Version 8.1.7.4.0 - Production on 18-JUL-2003 10:54:01

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.

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
I can not find any errors in the installation log. Only this warnings in the make.log:

Has anyone an idea? Or a hint how to encircle the problem?
Best regards,
Dirk

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

To find the missing package execute following command to list installed packages and post the output:

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.

However its giving me an error on the second node.

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.
