    What OS?
    What Oracle version?

    It's pretty easy to drill down with OEM, i'm assuming you do not have OEM?

    high CPU usage SQLs are those which has high

    parse_calls
    buffer_gets

    v$sql shows that (you might want to divide buffer_gets per executions since buffer_gets is cumulative)

    hi, if in oracle 9i,
    there is cpu_time in v$sql, and cpu% in statspack report.

    Also you can monitor it from unix, like prstat/top/ps find the spid and check the sql.
