When I was installing and configuring OAM with WNA using the Kerberos plugin, I had the need to trace what was happening while the plugin was trying to log me on.
Weblogic has loggers configured, and by setting the log level of oracle.oam.plugin to TRACE:32, the plugin could be traced. Unfortunately, oracle.oam.plugin is a child of the root logger, so all tracing will be mixed with other traces/logs.
A seperate logger for oracle.oam.plugin can be created however. In the enterprise manager console, under Weblogic domain, select the server you want to trace, and select “logs/log configuration”.
Select “view: loggers with persistent log level state”. Below, you’ll find a box “Name” under Specify Loggers.
In this box, type “oracle.oam.plugin”.
Once this logger is defined, a seperate log file can be defined for this logger. Plugin traces are now seperated from other log files and can be tailed with Linux while debugging/tracing.
