    I found the problem. All Workstation had "PANDA" Antivirus, I unistalled this program and the problem disappeared.

    Thanks to all.... I hope that my experience will be useful for you

    Hi,
    I am getting ORA-12571 TNS packet writer failure.
    what could be the reason ?
    Thanks,

    What is your operating system? Could you post your 'listener.ora', 'tnsnames.ora' and 'sqlnet.ora' files?

    I uninstalled the firewall, antivirus, and tried even uninstall and reinstall the network adaptor, check the entries in TNSORA and sqlnet.ora files all is fine, Its ping to the network address but not to the SID???

    What possibly be wrong? Any tips please!
    I will be greatful.

    Thanx

    DB:3.73:9i On Nt 4.0 Sp6 Dca Error Ora-12571 Creating And Starting Oracle Instance x7


    Hi folks, I'm on NT 4.0 SP6 and I'm trying to install the Personal Edition of Oracle 9i with General Purpose database and the Database Configuration Assistant displays error "ORA-12571: TNS PACKET WRITER FAILURE".

    I've read a lot here in the installation forum; I've tried installing from the /install/win32/setup.exe, I've
    tried different database types, running the DCA standalone after the install, and I still get this error.

    I beleive my system specs are adequate, ie. disc space, memory, cpu, etc...;

    Also, in the beginning of the install it tells me that I should have MTS (Microsoft Transaction Server) installed. Is this true? Do I really need MTS for a 'personal edition', non-networked version of 9i?

    Can anyone help me solve this problem?

    Additionally:
    I saw someone respond that Personal Edition was only for
    Windows 98. I don't beleive that this is true. I know folks that have it installed on XP and 2000, as well as 98.

    There seems to be a lot of problems with DCA posted in the installation forum. Why doesn't Oracle fix it so it works right?

    Many thanks for this forum.

    DB:3.64:Ora-12571: Tns:Packet Writer Failure ca


    We perform a cold backup (shutdown the instance, backup files to tape, then restart the instance) every weekend. Every Monday morning the first .NET application that uses ODP produces an "ORA-12571: TNS:packet writer failure" error. When the same application executes again (or any other ODP application), the error does not appear.

    We are using version 9.2.0.2.102 of ODP. Is this a known issue and is there a fix for it?

    DB:3.64:Ora-12571: Tns:Packet Writer Failure ca

    You can call ClearPool or ClearAllPools on the connection object, which will recycle your pool. Most admins call this after they bounce the DB.

    The other solution is to use RAC with Fast Connection Failover by setting HA Events = true in the connection pool. You must have RAC to use this attribute.

    Hi,

    I am experiencing the following error on a Oracle client PC:
    ORA-12571 : TNS Packet Writer Failure. The client PC cannot access any Oracle database, even by using Sql.
    The networking environment seems to be 100 % OK.
    Analysing the listener trace on the server did not help, nor did re-installing the Oracle client.

    Any idea about the problem ?

    DB:3.57:Can't Populate Blob... cf


    I'm using VB6, Oracle 8.1.6, The Oracle 8.1.6.2 OLE DB driver and ADO 2.5. I can populate all other fields in the table, but I can only put nulls in the BLOB. This occurs using OraOLEDB.Oracle as the provider.
    I get error: ORA-12571 TNS: Packet Writer Failure.

    But, if I go into Access 97 and link the Oracle table, then open it as an Access recordset, I have no problem writing text data to BLOB. Gotta be a driver problem.

    DB:3.57:Can't Populate Blob... cf

    Since you're using the Oracle OLE DB provider, I'd suggest that you post this question to the OLE DB forum.

    Note that I recently posted code that walks through BLOB and CLOB stuff to this forum-- I believe it contains both ODBC and OLE DB paths...

    My OCCI client multithread via pthreads and build against 10.2.0.4 client and my database is 9.2.0.8

    I've check my environment, specifically firewalls, and confirmed they arn't closing sockets, or dropping out of state packets etc..

    I had through it was I build my environment without the THREADED_MUTEX, but since changing this it still happens (prehaps less often)..

    On occasion my app will core dump, no doubt relating to code not handing this error properly.

    I havent anything relavent from google/metalink on this error..

    Any help would be much appreciated!

    Hello everybody,

    I installed Oracle 9i R2 on Windows 2000 Professional. Everything is fine as long as the computer is not part of a domain. When I join the computer to the network domain, the database doesn't startup anymore.

    If I try to install Oracle and create the database when the computer is joint to the domain, I get the error message ORA-12571 TNS: packet write failure. and the wizard is stopped, and the database is not created.

    Please help me.

    DB:3.42:Installing Oracle 9i R2 On Windows 2000 Professional 8m

    Check your init.ora (or spfile) for db_name and db_domain and see if your domain name is included in there. You might also have to take the names.default_domain out of your sqlnet.ora file.

    If you're building a database for the first time, and that's where it's failing, don't specify a domain on creation (ie, leave the sid and the global db name the same)

    [2011-03-04 16:29:03.488 'App' 5608 error] ODBC error: (08S01) - [Oracle][ODBC][Ora]ORA-12571: TNS:packet writer failure

    [2011-03-04 16:29:03.488 'App' 5608 error] Failed to intialize VMware VirtualCenter. Shutting down...

    If I test the connection under ODBC settings, I get exactly the same error [jpg attached]

    has anyone seen this before?

    Check for TNSListener services in services and ensure that is continousally running.
    Check for Oracle database is running or not.
    Check for oracle related services in services box.All services realted to oracle must be start.

    Did you connect to any other versions of Oracle from this same machine? I've noticed that if connecting to
    multiple versions of oracle, or if using multiple oracle
    products (forms, dba studio, reports) for multiple versions on the same pc, the tnsname.ora file that is used by
    a product may be different than you expect.

    Make sure the tnsnames.ora file that dba studio is using
    has the correct entries for the database you are trying to connect to.

    I know this has been talked about before but nobody seems to have given an answer which helps me.
    I recently completed the intro 9i:SQL course and have returned full of enthusiasm to start playing. I have d/l the Oracle9i Database Release 2 Enterprise/Standard/Personal Edition for Windows NT/2000/XP and installed onto my Win2000 Laptop. Everything installed o.k. except for (surprise, surprise) the database configuration assistant which would not create a database. I tried again after completing installation and received the same error.
    ORA-12571 TNS packet write failure.

    If there a fools guide to installing, and getting a database running on a single user machine which I could then use to familiarise myself with.

    I, at least a manual method of starting a database and then how to log in for the first time through SQL+

    All help very much appreciated.

    I am also trying to install Oracle 9i release 1 on a windows 2000 server SP1 - a test server, that is. It is not connected to a network and does not belong to a domain. When the installation gets to the database configuration assistant processes, it stays there for ...eternity... and does not continue. If I stop the process, I cannot log in to the database using SQL Plus with trial login name SYSTEM and password MANAGER.

    Can anybody guide me on this? I'm a newbie on Oracle.

    Now i am connected to SPACE from that m/c. which has only Oracle 9i client and then shutdown the database SPACE, but
    after shutting down client is not dynamically connecting to the database UIIVS2,though I have written "FAILOVER = TRUE" in tnsnames.ora.

    It is giving error like :-
    ORA-12571: TNS:packet writer failure

    when I am attempting test connection it is giving error
    ORA-01034: ORACLE not available

    What more I have to do for connecting dynamically UIIVS2 when SPACE is down.
    If the database located in separated m/c. is there anything more need to do.

    If you weren't shutting down the database, this was probably a transient failure. If it recurs, you'll want to enable SQL*Net tracing to diagnose the root cause.

    As far as shutting down the database before rebooting, if this is a production database, then you absolutely should be shutting down Oracle before rebooting. If this is a development database, it is probably less critical.

    DB:3.13:Ora-12571....Tns Packet Writter Failure....Oh What Can We Do? f9


    Hi Gurus!

    Here in our department we are getting the above problem frequently while trying to connect to the oracle database through SQL*Plus/Form/Report Builder etc. I have observed that on the client side where developer 6i is installed even we didnt perform any transaction/activity, we get the above problem!

    For the solution even i have tried following but didnt work,
    1- Uninstall and Reinstall all of the developer6i.
    2- Removed all related registry entries and files.

    The only thing which worked is to clean up all the system and to Reinstall the Operating System (windowXP).

    Which is very time taking and painfull to repeat it.

    Please have a solution for this!!!

    Thanks in advance

    When I intall Oracle Form 6 in my PC all my apps including SQL*Plus have the same error ORA-12571: TNS:packet writer failure.

    Thanks.

    Hi,

    This 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)

    Try this solution.
    btw. on internet is too many articles reg this error.

    DB:3.12:Tns Error After Install mm


    I have installed Oracle 8i (v8.1.7) on my Win2000-based PC and everything seems to work fine. SQL*Plus connects OK. Then I installed Forms Developer 6i. Installation went fine. But when I try to start up the SQL*Plus that came with it, it does not connect to the database. The SQL*Plus that came with 8i Personal still connects fine.

    I created the necessary TNSNAMES.ORA entry and followed all the installation instructions, but I keep getting a ORA-12571: TNS:packet writer failure. Why does this happen? Does anyone know how to fix this problem?

    I've seen there is another thread in this forum regarding
    "ORA-12571: TNS:packet writer failure"
    caused by ODP.NET. But it seems a dead thread. So I post this new topic.

    During normal utilization of database (without shutdown and restart of DB instance) from ASP.NET pages of web application, it happens (sometimes, it is not deterministic) that execution of
    Oracle.DataAccess.Client.OracleDataAdapter.Fill (that executes Oracle.DataAccess.Client.OracleCommand.ExecuteReader)
    raises
    [OracleException: ORA-12571: TNS: packet writer failure]

    The version of ODP.NET I'm using is 9.2.0.2.102. Is there a known bug that affects ODP.NET and causes ORA-12571?

    Thank to everyone that could help me

    DB:3.11:Ora-12571: Tns: Packet Writer Failure c3

    Found that thread:

    ***
    ODP.NET 920401 introduced the concept of validating a connection before giving it to an application. Of course, it is expensive and should be used wisely. An excerpt from the Readme:

    ODP.NET has introduced a new connection string attribute "validate connection" that should be set to true in order to validate connections coming out of the pool. By default, this property is set to false.

    Note that validation causes a round trip to the database for each connection coming out of the pool, which is very expensive in terms of performance.
    Therefore, this attribute should be used only if absolutely necessary.

    You lost your connection to the instance. Could be a network problem,
    intentional restart of the database, etc. Restarting the servers reconnects
    to the database. You may want to look at another message thread in this

    Hi folks, I'm on NT 4.0 SP6 and I'm trying to install the Personal Edition of Oracle 9i with General Purpose database and the Database Configuration Assistant displays error "ORA-12571: TNS PACKET WRITER FAILURE".

    I've read a lot here in the installation forum; I've tried installing from the /install/win32/setup.exe, I've
    tried different database types, running the DCA standalone after the install, and I still get this error.

    I beleive my system specs are adequate, ie. disc space, memory, cpu, etc...;

    Also, in the beginning of the install it tells me that I should have MTS (Microsoft Transaction Server) installed. Is this true? Do I really need MTS for a 'personal edition', non-networked version of 9i?

    Can anyone help me solve this problem?

    Additionally:
    I saw someone respond that Personal Edition was only for
    Windows 98. I don't beleive that this is true. I know folks that have it installed on XP and 2000, as well as 98.

    There seems to be a lot of problems with DCA posted in the installation forum. Why doesn't Oracle fix it so it works right?

    Many thanks for this forum.

    Hi,

    I have installed Net8 and SQL*Plus from 8.0.5 on SuSE Linux 6.0.
    Using SQL*Plus from Linux to a Server V7.3.4.2 on Win NT works
    OK, but using it against a Server V7.3.4.0.1 on Solaris 2.6
    gives the error
    ORA-12162: TNS: service name is incorrectly specified

    The listener logfile on the Solaris server shows that tnsping
    and the connection startup from SQL*Plus go through.
    The connection string traced by the listener looks the same
    as when connecting to the same instance from a HP-UX client.

    The Linux client logfile cli.trc contains the following error

    But in the TNSNAME.ORA file is working fine. meaning SQL*Plus and other Oracle client can connect.

    How can I solve this ploblem?

    Okay, here's an interesting conundrum:

    I have a machine running XP Professional and have tried to install one of our Forms6i applications onto it. The installation creates two oracle homes, one is 8i and uses the newer networking software. The other (in which the forms runtime resides) is 8.0 and uses the net80 version.

    Now for the fun part: when I try to connect to the database (Oracle 9i database -- Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production
    With the Partitioning, OLAP and Oracle Data Mining options

    Hi All,
    ORA-12571 is a network error. Whenever network is heavily loaded ORACLE throws this error. This is a bug in win NT 4. Check which service pack are you using.
    This bug is been succesfully corrected by MICROSOFT and service pack has been released. Try to get service pack 6a. This service pack is released after service pack 6. This service pack will get from MICROSOFT website.

    I was also getting this error but everything calm.
    I recommended this to my SYS ADMIN and network guy done accordingly.

    I think it will definately solve your problem. For any query can contact me on goel_sumeet@yahoo.com.

    Please help me! Very urgent...

    DB:2.82:Ora-12571 ds

    ORA-12571 indicates a broken connection between the Oracle client and the server. This could be (as Justin points out) due to a temporary network glitch or due to the death of a server process. In either case, the client side marks the connection as broken and in this case has cleaned up the assosciated data structures. Further operations return ORA-1041 as as result.
    The only option at this point is to reestablish the connection to the server from your application or restart the application. Check any kind of memory leak, handle leak, etc. especially when you have a long running process.

    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.

    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.

    When I try to connect to my remote or my local database using SQL*Plus 8.1.7 everything is OK.

    The problem is when I try to connect using SQL*Plus 8.0.6 or any tools from Designer6i or Forms6i I get the error:

    ORA-12571: TNS:packet writer failure.

    The config files tnsnames.ora and sqlnet.ora are the same on both oracle homes.

    Any clues would be appreciated. Cheers.

    I create everything in the DB (roles, repos owner user and tablespaces) with success using sqlplus 8.1.7.0.0 coming with Oracle 8.1.7.

    following message:

    It's a nightmare!

    I am attempting to get a RH Linux 6.0 machine to see our Oracle 7.3.4 server, running on a remote Solaris machine. I got Oracle 8.0.5, which I was assured would work. I fought with it for a while, and finally I think I've got it installed properly. TNSPING says OK when I point it at our database. The problem is that when I try to use sqlplus (or perl DBD, which is my ultimate goal), it give me:

    ORA-12571: TNS: packet writer failure

    I am certain that the server is running smoothly, so this is definitely a problem on the Linux machine. Does anybody know what I'm doing wrong? Thank you very much.

    Never mind. After hunting through the old messages in this forum, I found the answer: add the line

    DISABLE_OOB=ON

    Hi Gurus!

    Here in our department we are getting the above problem frequently. I have observed that on the client side where developer 6i is installed even we didnt perform any transaction/activity, we get the above problem!

    For the solution even i have tried following but didnt work,
    1- Uninstall and Reinstall all of the developer6i.
    2- Removed all related registry entries and files.

    The only thing which worked is to clean up all the system and to Reinstall the Operating System (windowXP).

    Which is very time taking and painfull to repeat it.

    Please have a solution for this!!!

    Thanks in advance

    Another possibility is spyware. We encountered that recently and ran Ad Aware to remove the spyware.

    After that you may encounter another error (I can't remember which one exactly) which can be resolved by donwloading LSP-fix (http://www.cexx.org/lspfix.htm).

Few days back we started noticing a strange issue.We can connect to oracle 11.2.0.3 but not 11.2.0.1.what happens is when i type in sqlplus username/password@oracle11.2.01 sqlplus connects after a while. It takes good 1.25 minutes.and sqlplus username/password@oracle11.2.0.3 connects instantly.One interesting thing is when i say sqlplus username/password, sqlplus instantly connects to oracle11.2.0.1.

    Hi folks, I'm on NT 4.0 SP6 and I'm trying to install the Personal Edition of Oracle 9i with General Purpose database and the Database Configuration Assistant displays error "ORA-12571: TNS PACKET WRITER FAILURE".
    I can't get through the db configuration; All else appears
    to install well. I looked up this error and it says to contact Oracle support.

    I've read a lot here in the installation forum; I've tried installing from the /install/win32/setup.exe, I've
    tried different database types, running the DCA standalone after the install, and I still get this error.

    I beleive my system specs are adequate, ie. PIII, disc space, memory, cpu, etc...;

    Also, in the beginning of the install it tells me that I should have MTS (Microsoft Transaction Server) installed. Is this true? Do I really need MTS for a 'personal edition', non-networked version of 9i?

    Can anyone help me solve this problem?

    Additionally:
    I saw someone respond that Personal Edition was only for
    Windows 98. I don't beleive that this is true. I know folks that have it installed on XP and 2000, as well as 98.

    There seems to be a lot of problems with DCA posted in the installation forum. Why doesn't Oracle fix it so it works right?

    What more I have to do for connecting dynamically UIIVS2 when SPACE is down.

    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!

    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"!

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"!

    DB:2.68:Tns-12571 Error From Reports6i kp


    Hi

    I am using Reports 6i in client/server environment. In one workstation (HP notebook with Windows XP) we receive TNS-12571: TNS:packet writer failure when trying to connect to database. We test this against different Oracle database versions (8i, 9i, 10g) on two different network environments - the result is the same. On the same computer we have installed 10g client and it connect successfully to the databases.
    Have someone experience with such problem?

    DB:2.66:The Vmware Virtualcenter Server Service 2.5.0.64192 Terminated Unexpectedly m3

    I appreciate the suggestions but we have tried all the simple stuff like that we can think of. The real issue is that the 12571 error is such a generic Oracle error that it could be almost anything. The machines are on the same subnet so we aren't firewalled and the network shouldn't be an issue but that is about the last thing we need to check. Simply because the error code given basically states that the DB was not available at the time it tried so it quits.

    For the time being we set the service to restart immediately after it goes down so at the very least it should go back up pretty quickly, but it will still interrupt backups or anything that might be going. We did a trace in the Oracle client and are currently going through that to see if we can find anything.

    To answer your questions we checked all updates to the client (10.2.0.4) and rebuilt the system DSN to ensure it was using the 10.2.0.4 ODBC client - what specific settings would you suggest I check in the ODBC client that would be different between 9i and 10g? Realize that this ran for a year with no issues on 9i - we just don't want to fail back to it if we don't have to.

    Please help

    From memory this was often due to environment variables not being set correctly.

    Make sure the following are all correctly set:

    ORACLE_SID
    ORACLE_HOME
    LD_LIBRARY_PATH/SHLIB_PATH/LIBPATH (whichever SCO uses)

    make sure you use svrmgrl rather than sqlplus and use connect internal rather than connect as sys or system.
