批量获取oracle的AWR报告方法
awr快照默认每小时抓取1次，生成awr报告则通常时间跨度为1小时，如果想看1天的每小时的awr则需要手工一个个生成，选择开始快照号和截止快照号，可考虑用以下方法批量生成。
先查看当前有哪些时间的快照
set linesize 300
col snap_id for 99999999
col dbid for 99999999999
col startup_time for a20
col begin_interval_time for a20
col end_interval_time for a25
alter session set NLS_TIMESTAMP_FORMAT='yyyy-mm-dd hh24:mi:ss';
select dbid,instance_number inst_id,snap_id,begin_interval_time,end_interval_time,startup_time
from dba_hist_snapshot order by 1,2,3;
脚本内容如下：

/*

-- 用法:
-- @awrbatch <dbid> <instance_num> <start_snap> <end_snap>
--
-- 示例:
-- @awrbatch 2580850603 1 32302 32310

/生成的报告会输出到目录下
select directory_path from dba_directories where directory_name='DATA_PUMP_DIR';
