ML 论坛里的所写的Oracle-base的脚本，由于某些原因(你懂的)，给不会的童鞋贴在这里
-- -----------------------------------------------------------------------------------
-- File Name : http://www.oracle-base.com/dba/1 ... ple_awr_reports.sql
-- Author    : DR Timothy S Hall
-- Description  : Generates AWR reports for all snapsots between the specified start and end point.
-- Requirements : Access to the v$ views, UTL_FILE and DBMS_WORKLOAD_REPOSITORY packages.
-- Call Syntax  : Create the directory with the appropriate path.
--             Adjust the start and end snapshots as required.
