Event 10246 - Trace PMON Process
This event can be used to trace the actions of the PMON background process.
This event can only be enabled in the PFILE using: event = "10246 trace name context forever, level 1"

The ALTER SYSTEM command does not appear to work for this event.
There only appears to be one level for this event (levels 5 and 10 appear to generate the same output as level 1)

Event 10500 - Trace SMON Process
This event can be used to trace the actions of the SMON background process.
This event can be enabled in the PFILE using:    event = "10500 trace name context forever, level 1"
