Are there any system views I can look into to get CPU usage for the running programs from the query?
select USERNAME,PROGRAM, terminal from v$session where username is not null;

SELECT n.username,
s.sid,
s.value
FROM v$sesstat s,v$statname t, v$session n
WHERE s.statistic# = t.statistic#
AND n.sid = s.sid
AND t.name=’CPU used by this session’
ORDER BY s.value desc;

session level

select * from v$sesstat
  where statistic# = 12
  order by value desc;

CPU usage for parsing

select (a.value / b.value)*100 “% CPU for parsing”
from V$SYSSTAT a, V$SYSSTAT b
where a.name = ‘parse time cpu’
and b.name = ‘CPU used by this session’;

To determine percentage of Recursive CPU Usage

select (a.value / b.value)*100 “% recursive cpu usage”
from V$SYSSTAT a, V$SYSSTAT b
where a.name = ‘recursive cpu usage’
and b.name = ‘CPU used by this session’;

This sould get you started
