About getting AWR report

Can I generate an AWR report for an AWR snapshot before setting "CONTROL_MANAGEMENT_PACK_ACCESS" to "DIAGNSOTIC"?

 

For example, the current setting

•   CONTROL_MANAGEMENT_PACK_ACCESS: NONE
•   STATISTICS_LEVEL: TYPICAL
•   SNAP_INTERVAL: 1 hour
•   RETENSION): 8 days

 

When

 

Can I get a 10/20 AWR report in the following time series?

10/19

10/20

10/21

10/22

  (1) Execute the following SQL

       Alter system set CONTROL_MANAGEMENT_PACK_ACCESS = DIAGNOSTIC;

  (2) Execute the AWR report acquisition command (awrrpt.sql)   to acquire the AWR report from 10/20 0:00 to 10/21 0:00.
