ORA-12571: TNS: packet writer failure tips

Oracle Error Tips by Stephanie F.

 

The Oracle docs note this on the ora-12571 error:

 

ORA-12571: TNS:packet writer failure
 
Cause: An error occurred during a data send.
 

Action: Not normally visible to the user. For further details, turn on tracing and reexecute the operation. If error persists, contact Oracle Customer Support.

Internet sources offer information on ORA-12571 which applies to Applications Desktop Integrator; version 11.5.9, occurring on any platform. The issue here is regarding an inability to start ADI because of ORA-12571 intervening, as following:

Logon to ADI fails with ORA-12571:TNS:packet writer failure
ADI->Signon->Enter username/password

The cause of ORA-12571 is stated to be a problem with the Oracle operation interfering with other applications, such as an anti-virus application, "panda antivirus is installed on the same machine that prevented ADI to work."

The solutions are given below, and may be used to troubleshoot the resolution of ORA-12571:

1. Disable / Remove Panda antivirus.

2. Start ADI again or re-install ADI if the issue persists.


Or install ADI on a machine where no other software i.e. 3rd party software is installed.
..

Technically, this is not an ADI issue, it is SQL*Net (i.e. 8) issue that ADI uses.

It is more common with the Discoverer product which is also a client side product running SQL*Net.

ORA-12571 can be caused by Spyware, Firewall, Network, MacAfee and Panda Antivirus.

MacAfee and Panda Antivirus have been reported to block the access and cause the error.
Users probably wouldn't be able to connect to their database via SQL*Plus.

The options are:

1. Log a bug against SQL*Net for the issue.

2. Contact Panda or MacAfee support centers and log an issue with them stating that they cannot connect to Oracle SQL*Net and find out what to do because everything seems to work without Panda or MacAfee running.
