补充:

Oracle 10g/11g AWR/STATSPACK,

在10g/11g同时开启AWR/STATSPACK功能时,发现AWR不能定时收集信息,只好用cron job代之,

crontab -l

# run awr/stats pack
0,10,20,30,40,50   * * * * /home/oracle/utility/statspack.sh 10 >> /home/oracle/utility/log/statspack10_10.log 2>&1
0,10,20,30,40,50   * * * * /home/oracle/utility/runAWR.sh 10 >> /home/oracle/utility/log/runAWR_10.log 2>&1

col snap_interval format a20
col retention format a20
select * from dba_hist_wr_control;

      DBID SNAP_INTERVAL        RETENTION            TOPNSQL
---------- -------------------- -------------------- --------------------
3258538501 +00000 00:10:00.0    +00030 00:00:00.0    DEFAULT

--10 分钟间隔,保留30天
exec dbms_workload_repository.modify_snapshot_settings(interval=>10, retention=>30*24*60);
