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 sqlnet expire_time 10 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

We use ODP.NET from ASP.NET applications, and we suspect the firewall closes connections that have been in the connection pool too long. Sometimes we get an "ORA-12571: TNS packet writer failure" error, packet writer failure and sometimes we get "ORA-03135: connection lost contact." I was wondering if someone has run into this and/or has an understanding of the difference between the 2 errors. oracle odp.net tns ora-12571 share|improve this question edited Apr 16 '10 at 20:02 Peter Lang 35k17103128 asked Apr 16 '10 at 19:36 Philippe 2,4272334 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted Using a mobile phone analogy: ORA-12571 (Failure) Means call is dropped.

This doesn't tell you why the connection was lost, though. It may have been terminated by the server because the server failed to recieve a response to a probe for a certain amount of time, and assumed that the connection was dea
