Regarding rman user session

Question

hi all,
i need to create a trigger for tracing a particular user session or rman session so that only one trace file is used throughout, regardless of there number of logins or logoff
thanks

Answer 1

Create a logon trigger, that checks for a certain login-name
We do the same for checking applications that log on.
Remember that if you're calling a procedure from the logon trigger, you have to disable the trigger every time you work/develop on the procedure.
Otherwise the trigger gets Invalid and all logons are denied
I can't show you the code we use now, because our storage-network has failed
Edit: Back online
The code
CREATE OR REPLACE TRIGGER check_logon_logging
  after logon on database
begin
  illegal_appl_prc;
end;
