Is there any way to find who/what is causing all these rollbacks. If
"logminer" is the only solution, which table.column of v$logminer...
view tells me whether the operation was "rollback"?
thanks,

You could try looking in the "operation" column (of v$logmnr_contents), for
starters. But, in fact, Log Miner won't help. As far as redo is concerned,
a rollback is just as committed as a commit: it just happens to leave data
in exactly the same state after as before the transaction.

look at v$sesstat to find the top-rollback-sessions (you may need to join to
v$statname.statistic# to get the statistic names).

Jonathan: Its an web based application and our web server is Apache .
HJR: I am wondering whether its possible to find the statements
getting rolled back.
Stephen: I can easily get the statistics (in fact I already got it)
Since most of our connection is persistent and the "user rollbacks" is
spread across the sessions almost uniformly, it is hard to get any
useful info out of it (other than knowing they do lot of rollbacks).

Check v$sysstat for:
"rollback changes - undo records applied"
and see if this is just a couple or so changes
per call.
