Packet failures - ORA-12571 and TNS-12637

Hello there -
I've received several packet type errors for a Remedy application running Oracle 11g. Two of the errors are as follows - ORA-12571: TNS:PACKET WRITER FAILURE and TNS-12637: Packet receive failed. Apparently the DB seems to come down for a few moments and than come back up again. Anyone have any ideas on solutions?

Anyone have any ideas on solutions?I see Oracle as victim; not culprit.

ORA-12170 and TNS-12535

Hi everyone
My servers are in a separate location and we are accessing our databases from my office.
The developers say that they couldn't access one particular db from their machine.
The errors they receive when they try to connect using some tool is:
TNS-12535 TNS:operation timed outWhen I request them to TNSPing or when they access from Sql Plus(instant client), this is the error they receive:
ORA-12170: TNS:Connect timeout occurredOne of the developers are using Oracle XE and he too faces the same scenario.
So, where should I trace this problem from.
We all could ping to the machine where the Oracle resides.
Please advice.
Thanks in advance.

I have done a trace on the client side and here is the output:

'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.

Ora-12154 vs. tns-03505

Since both ora-12154 and tns(ora)-03505 deal with not being able to locate a connect string in tnsnames (or other naming method), has anyone ever seen a good definition of exactly what differentiates between the two? What little variable would trigger the issuing of one error msg.vs. the other?
I know how to resolve them. The web is full of descriptions on resolving the problem (some of them are even valid! ;-) ). But I've never seen anything that would define why you would see an ora-12154 on time, and an tns-03505 another time.
Inquiring minds want to know! (Since this deals with published error codes, it's <i>somewhat</i> less arcane than how the archiver determines the "first" member of a redolog group! :-)

Senior Oracle DBACould be. I never picked up on any pattern of behavior before (thus my question). A simple test seems to bear that out:

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.

ORA-12571 TNS : Packet Writter Failure

Hi all,
When I try to connect the DBA Studio (in the WIN 2000 SP 3), client of Oracle , the error message is
"ORA-12571 : TNS : Packet writer failure."
But in the TNSNAME.ORA file is working fine. meaning SQL*Plus and other Oracle client can connect.
Only the GUI application(like DBA Studio,enterprise manager) are giving this error.
How can I solve this ploblem?
Thanks.

yes I few more tnsnames.ora file other directory for other version and application.
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)

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"!

This question probably best belongs on the General database forum.

ORA-12570 TNS PACKET FAILURE

I am trying to instal oracle(8 1 5) on my window 2000. Everything works fine but when it get to were to build the starter database, I get thisd message
ora-12570 TNS packet failure.
Can someone take me what I need to do to fix this problem. I can't get it work but we I get to the service area the database was installed.
Please this is a big problem to me. I will really appreciate quick respond if you have come across a similar problem.
God bless you.

Try using the option to build scripts to create the database instead of creating the database. Then run the script to create database from the cmd window.
If using TCP/IP, can you ping localhost successfully ?

REP-1401 and ORA-12571

Dear All,
Oracle fusion middleware version (pfrd) : 11.1.1.4
OS : Windows 2008 X 64, 2 CPU and 8 GB RAM
When we run a huge report we are encountering REP-1401 and intermittently with accompaning error ORA-12571, but when the same report ran for one month report it is working fine.
REP-1401: A fatal PL/SQL error occurred in program unit cf_anct_docsformula.
Since the report is running fine for 1 month period, we concluded that this issue is not a report error or formula columns used and narrowed it to some configuration or ORACLE bug.
We have increased the JVM heap and tired but we couldnt able to get the report. Also we tried searching in oracle support but no hits.
Please let me know if any one had encountered this issue.
Regards,
Anand.

Error – ORA-12571 is related to TNS:packet writer failure and error occurred during a data send.
For further investigation, you need to turn on tracing to collect the logs.
