Hi,
Can anyone help me ?? I have installed Oracle 8i under Windows XP and I am getting the above error. While connecting thru JDeveloper It is giving Network Adapter error.
Reply Appriciable.
Thanks in Advance.

How did you uninstall Oracle? You cannot use the Oracle Installer to remove Oracle. To completely remove Oracle from a Windows system you must edit the registry and several other steps. If you need these procedures, send me an e-mail: [email protected]

ORA-12571: TNS:packet writer failure 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,

hi,
thanks for reply,
I wanna let u know that this is my personal lappy & i have installed apps dump on it in Linux & connect it through VM player in Window environment. I have recently purchased a new Antivirus K7 & installed it on my Lappy. i wanna know does this impact your application or Dbase Bcoz the application is running fine after starting the services in linux.
The only thing is that i am not able access the database through TOAD or SQL*Plus. the same error i am facing in both.
So
shud i uninstall the antivirus on this And this is the only solution to it ?
If yes, then how do i fix it again when i'll reinstall it Bcoz i need Antivirus as well.
kindly suggest.
thanks

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

ORA-12571-TNS: PACKET WRITER FAILURE

Hi All,
am using oracle 6i and facing this problem when am connecting Forms to Database..
Error Encounterd:ORA-12571-TNS: PACKET WRITER FAILURE.
Plz help.
Regards,
Neha

this error usually network problem..... i googled it found some solutions try
his is usually due to an improper sqlnet.ora setting. Here are some possible causes and remedies:
** Loose network cables. This error has been observed when there was a loose cable connection to the SCSI disk array (on an Oracle Parallel Server system). Related errors were also subsequently noted in the NT event log.*
** IP address conflict (Oracle 9.0.1).*
** Authentication services. One solution is to edit the sqlnet.ora file and change the line:*
SQLNET.AUTHENTICATION_SERVICES= (NTS)
to
SQLNET.AUTHENTICATION_SERVICES= (NONE)
After saving the updated file, he was able to hit the retry button on the install and the creation of the database succeeded.

Help - Newbie - getting "ORA-12571: TNS: packet writer failure" ERROR

Hi all,
Not sure where to post this, so trying for the general forum to start...
I have also searched and read all the forums for help on this already as well the Oracle documentation and anything I could find from several on-line searches, etc.
I have Oracle 8i Enterprise Edition and Oracle Forms 6i installed on Win2K. Everything worked fine when it was just Oracle 8i running, ie: connecting to the database in SQLPlus Worksheet, but when I try and connect to the database in the datablock wizard in forms I get the ORA-12571: TNS: packet writer failure error!
Don't tell me to re-install, I've done that like 6 times already. I've check the tnsnames.ora files and tried that fix already. I don't know what else to try short of fdisk and redoing everything from scratch again, but I don't have time for that as this machine is used daily for other tasks.
Any help or suggestions are appreciated!!!
Thx in advance!
Michelle.
PS: Note to Oracle support staff if you are listening (pardon the pun). Your one line of help for ORA-12571 in the existing support files is rather similar to the Hitchhikers Guide to the Galaxy's info for Earth... After seeing how many people have posted about this problem and how few resources or real answers there are out there, you might want to consider updating the info on this error, because is deserves something more than "mostly harmless"!

Ora-12571 TNS:packet write failure

Hi all
I installed Oracle 10g database, and after that Oracle 6i FORMS
Then suddenly I began getting error Ora-12571
I uninstalled 10g database, then uninstalled FORMS and installed forms once more, but there still error
What may be the reason and how can I solve it?
Thanks...

Apart from that is there any specific need to use 6i forms? Why not Oracle Forms 10g?

"ORA-12571 : TNS : Packet writer failure."
But in the TNSNAME.ORA file is working fine. meaning SQL*Plus and other Oracle client can connect.

How can I solve this ploblem?
Thanks.

For this same version HOME directory, only one file is there.
so, SQL*Plus is connecting by using this file , but not for GUI applications.(DBA studio,Enterprise manager)

Can any one help me in this regard
Salman

with the new 9i install you may now have a new oracle home with a new tnsnames. ora
here you have to add the necessary connection profiles (or copy the old tnsnames.ora to the new).
look here also: Re: connecting to database
update: this is a double thread ....

TNS-12571:TNS PACKET WRITER FAILURE

Hello Oracle Gurus,
Our Oracle 9i database is hosted somewhere else and is behind the firewall. When accessing this database through TOAD, even after 2 minutes of inactivity, we get the "TNS-12571: TNS Packet writer failure" and we have to reconnect to the database again. This occurs in all of the client machines. The Oracle 9i database's firewall is open for the ip address from which we are using TOAD/SQL*Plus.
Is there any configuration that needs to be changed on the Oracle Client or server side to solve this issue? I appreciate your help.
Thanks,
Saku

Hi,
you can set sqlnet_expire_time option in sqlnet.ora file on the database server and set the time less than 2 mins. This to identify if the problem is because of some firewall configuration or other network related issue which causes the onnection to die.
this parameter should keep all the client connection alive but results in extra trafic.
