RE: Historical Plan & Time

Correction:  

c/snap_time/sample_time
c/snap_time/sample_time  

From: Allen, Brandon  

To find the details of the plan, you'd want to run something like this:  

select min(snap_time), max(snap_time) from dba_hist_active_sess_history where sql_plan_hash_value = <known plan_hash_value>  

Or:  

select sql_plan_hash_value, min(snap_time), max(snap_time) from dba_hist_active_sess_history where sql_id = <your sql_id> group by sql_plan_hash_value;
