（3）生成awr

需要通过awrrpti.sql脚本生成快照：

11:46:21 SYS@messay > @?/rdbms/admin/awrrpti.sql

（4）删除导入awr

查询当前快照

select snap_id,dbid,instance_number from dba_hist_snapshot order by 2,1;

删除导入的快照：

12:07:52 SYS@messay > exec dbms_workload_repository.DROP_SNAPSHOT_RANGE(LOW_SNAP_ID=>1207,HIGH_SNAP_ID=>1217,DBID=>353046371);

再次查询：

select snap_id,dbid,instance_number from dba_hist_snapshot order by 2,1;
