Oracle: Change AWR snapshot interval and retention

 SQL> execute dbms_workload_repository.modify_snapshot_settings (interval => 10, retention => 20160);

PL/SQL procedure successfully completed.


10 mins and 14 days in mins:

execute dbms_workload_repository.modify_snapshot_settings ( interval => 60,  retention => 1576800);    <-- 3 years in minutes

To get the current settings:

select
       extract( day from snap_interval) *24*60+
       extract( hour from snap_interval) *60+
       extract( minute from snap_interval ) "Snapshot Interval",
       extract( day from retention) *24*60+
       extract( hour from retention) *60+
       extract( minute from retention ) "Retention Interval"
from dba_hist_wr_control;
