Solutions for "ORA-12571: TNS Packet writer failure"

The "ORA-12571: TNS Packet writer failure" error fires every time we install a new piece of software, like Visual...

Basic or Norton Antivirus. This problem happens whith Oracle 7.1.6. and Form Builder 6. I have already tried almost all of the solutions but it still is not working.

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)
    

    After saving the updated file, he was able to hit the retry button on the install and the creation of the database succeeded.
