Automatic Workload Repository and Automatic Database Diagnostic Monitor

    and s.dbid = sn.dbid
    and s.instance_number = sn.instance_number
    and sn.status = 0
    and sn.bl_moved = 1;

Because of the overwhelming amount of data, the focus here will be on the dba_hist views that may be familiar from STATSPACK.  The column names are different from the STATSPACK tables, but the types of performance data collected by these STATSPACK tables are essentially the same as that found inside the dba_hist views.
