SQLID execution history

I use this script to find out how the sql run in the history

col buffer_gets_DELTA for 999,999,999
col buffer_gets_total for 999,999,999,999
col stat_time for a15
col end_time for a15
select sql_id,PLAN_HASH_VALUE,to_char(BEGIN_INTERVAL_TIME,'hh24:mi-dd-mon') start_time,to_char(end_intervAL_TIME,'hh24:mi-dd-mon') end_time,
BUFFER_GETS_DELTA,buffer_gets_total,round(cpu_time_delta/1000000) "cpu_time_del(s)",round(ELAPSED_TIME_DELTA/1000000) "ele_del(s)"
from dba_hist_sqlstat st, DBA_HIST_SNAPSHOT sn
where st.snap_id=sn.snap_id and
BEGIN_INTERVAL_TIME > sysdate-&days
and sql_id='&sql_id'
order by BEGIN_INTERVAL_TIME;
undefine snap_id
undefine sql_id

oracle dba_hist_sysmetric_summary

found this blog is helpful to get CPU and IO statistics on oracle database. http://shob-dbadmin.blogspot.ca/2012/12/how-to-find-total-io-of-database.html courtesy to  Shomil Bansal , below are hist writing, not mine. How to find total IO of the database instance Total IO of database instance is sum of the physical reads, physical writes and redo writes. There are several views to find these values. v$sysmetric  - Reports metric values for only the most current time sample 60 secs. v$sysmetric_summary  - Reports metric values for time sample of 1 hour. v$sysmetric_history  - Reports metric values every 60 sec from the time instance is up. Better way to analyse IO using this view to take deltas between two time periods. dba_hist_sysmetric_history  - All the above views are refreshed when the instance is restarted. This view, part of AWR, stores the historical stats. I have used this view for my report. Query: ====== set lines 350...
