Unwanted security Audit Failure event from Oracle database connect

Leoš Junek

Hello,

I am using Windows Server 2012 R2. There I am facing an unwanted Windows Security Audit log entry that comes with Oracle 11gR2 connect from one database on Windows server No.1 to another Oracle 11gR2 database running on another Windows Server. Database link is used. The connection from database to database is successfull, no errors, however every connect raise an entry in Windows Event Logs.

Can I exlude particular event with specific network source and crendetials from logging? It´s false positive. I do not want this error to occur in my Event log. Is it possible to persuade Windows not to log it?

I am not interested in filtering Event log in Event Log viewer. The logs are collected and processed automatically with external tool.

Below an example of logged event is provided.

Hope someone can tell whether it is possible or not due to security reasons.
