Fuser is not much helpful. In solaris 10 dtrace might help. The best way, if you are only running database on that box, is to do a snapshot of v$sessio or v$sesstat, and compare the sesstat difference after another snapshot, to find out:
which session;
which sql
is using most of the disk read/write.
