You can modify the snapshot collection interval using the dbms_workload_repository package.
The procedure dbms_workload_repository.modify_snapshot_settings is used in this example to
modify the snapshot collection so that it occurs every 15 minutes, and retention of snapshot data
is fixed at 20160 minutes (exactly 14 days):
-- This causes the repository to refresh every 15 minutes
-- and retain all data for 2 weeks.
exec dbms_workload_repository.modify_snapshot_settings -(retention=>20160, interval=> 15);
Setting the interval parameter to 0 will disable all statistics collection.
To view the current retention and interval settings of the AWR, use the DBA_HIST_WR_
CONTROL view. Here is an example of how to use this view:
select *
from dba_hist_wr_control;
DBID SNAP_INTERVAL RETENTION
