ORA-12571 TNS packet writer failure
I badly need your help regarding ORA-12571: TNS:packet writer failure.
I can access an instance using C:> set ORACLE_SID=SID and C:> sqlplus / as sysdba running this on the server machine it self.
but when i try to use:
c:> sqlplus sys[email protected] as sysdba
I get this error:

ERROR:
ORA-12571: TNS:packet writer failure
Enter user-name:
But when i try to run the following:
C:> set ORACLE_SID=SID
C:>sqlplus schema_name/password
I can access the instance.
Also I try to check the DB connection on remote users(TNS names), same error ORA-12571: TNS:packet writer failure . So all users cant access any of the instances from the server.

Make sure you set up your IP on hostname, not the «word» ipaddress,
HOSTNAME=(192.168.0.1), etc
ok, so in this case, try to delete all your listeners and its services via Oracle Net Configuration Assistant.
And then after you have no more listeners os services you create it and test it pointing the ip address.

ok, so if you use the listener you cannot connect
I had this issue but it wasn’t the firewall.
Can you post the listener.ora for us?
try to change it, pointing the host address as «localhost» or even the IP Address instead the «hostname». And then try to tnsping your service.
If necessary, re-create the listener.
In my case, re-creating the listener and configuring the local ip address instead hostname or even localhost worked well, and I could then connect to the DB.
Hope it Helps

tnsping your service and try again.

Oracle Managed driver — ORA-12571
We are having issues with Oracle Managed driver on Windows Server 2008 R2. The exception is below. It does’t happen every time.It happend 40 times today and in 95% of the cases it is on one or two specific methods. Is this a known issue? Currently we had to return to unmanaged driver because this was producing to many production incidents.
Thank you in advance,

Answers
This is not a known issue. Furthermore, we would like some more details about your environment:
1) Can you please specify the version of Oracle Managed driver you are using and in case you are NOT using the latest release then would it be possible for you to try the latest available and see if issue still reproduces.
2) I am assuming that you don’t run into these issue with unmanaged driver. When using unmanaged driver, are you using transparent application fail-over (TAF) feature?
3) Do you have any firewall setup or any antivirus running on you DB machine?
Any other special environment detail which could help us identify the issue.

ORA-12571: TNS:packet writer failure
i have oracle database 11g running on windows server 2008 release-2. Today morning our developer face ORA-12571 TNS: packet writer failure error while compile large store procedure in Toad and same error get while execute same store procedure through sql*plus. developers are not get this error while compile small store procedure and create table. this error only get when store procedure is large about more than 1000 lines.
As error in TNS Packet so i guess there is a problem in Network side or in sqlnet or tnsname file.
we try below step.
1. so first try to re-create the listener. delete and create the listener.
2. shutdown and startup the database. (if you get downtime from client) do not try this step on production.
3. check network cable connection. This error has been observed when there was a loose cable connection to the SCSI disk Related errors were also subsequently noted in the NT event log. try all cable jack in jack out and check problem still persist.
4. this error may occur if ip conflict on windows server (but in our case there is no ip conflict).
5.edit the sqlnet.ora in path D:/app/oracle/network/admin/sqlnet.ora and change below line.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
into
SQLNET.AUTHENTICATION_SERVICES= (NONE).
6. Try to de install antivirus if you have installed.
7. you may solve this error by modify below parameter using sysdba privileges.
alter system set shared_server_sessions=200 scope=spfile; (if it is null than set this value)
alter system set processes=300 scope=spfile;
alter system set sessions=500 scope=spfile;
restart the database.
If you resolve your error using above one of step than you are lucky but we not get solution and we still get ora-12571 error. so we log bug to oracle support.
oracle gives below solution.
1.1. Add the following parameters in the sqlnet.ora file on the CLIENT workstation:
TRACE_LEVEL_CLIENT=16
TRACE_DIRECTORY_CLIENT=<some_known_directory>
TRACE_FILE_CLIENT=client
TRACE_UNIQUE_CLIENT=ON
TRACE_TIMESTAMP_CLIENT=ON
DIAG_ADR_ENABLED =OFF — add this in case of 11g client
The default directory for sqlnet.ora file is $ORACLE_HOME/network/admin , if not specified differently by TNS_ADMIN environment variable.
If you need to restrict the amount of disk space used by only the long-term traces then you can also set the following:
TRACE_FILELEN_CLIENT=<file_size_in_Kbytes>
TRACE_FILENO_CLIENT=<number_of_files>
1.2. Reproduce the issue / error
1.3. Check if trace files were created.
1.4. Disable tracing by removing the TRACE lines from sqlnet.ora.
We collect the sqlnet trace file and send it to oracle support but oracle support didnot find any error in this sqlnet log files. so oracle support recommend to check below things.
we get solution by below steps
Oracle Support ask below question to us.
>> do you have any firewall in the setup?? if yes, please try making a connection from inside the firewall to the sb server??
we reconfigure the firewall in data centre and tell to data centre to some issue in our 1521 listener port. after the data-centre network reconfiguration we solved our issue. so at last you have to check your network configuration and firewall configuration to solve ora-12571 error.
—please give your expert comments if any others.
