Statspack (or AWR) will give you an idea of when the database is producing
the redo, and that can be enough for you to work out what is generating the
redo.
Then if you need to collect details for specific sessions, you could collect
details from v$sesstat for individual sessions. If you can't add your own
code to whatever you suspect is generting the redo you could perhaps using
triggers that fire after LOGON and before LOGOFF for specific programs, and
if you need more granularity before and after DML on specific tables - but
could end up collecting a lot of data that you will then work on. Th
regards
