My 817 DB is very busy generating archived log every 1/2 hour for 1 week or so or so while there is not seem to be any users or people doing anything. However we have process scheduler that I am suspicious of. v$sqlarea don't show any heavy sql's neither. I bonced the db once but didn't seem to help. The problem is that there is no Unix process show up so I can kill as this runaway job(s) is probably initiated via background. Can I look at any tables or views to help identify what is going on?
