本文介绍了一个使用Shell脚本批量生成Oracle AWR报告的方法。脚本通过接收参数实例名、开始时间、结束时间和报告类型，利用SQL*Plus连接数据库获取快照ID并生成HTML或TEXT类型的AWR报告。

上文里面的功能，对比着用shell来实现，比较好玩

用法：

bash ./dba_oracle_awr.sh -s ORCL -f 20110312070000 -t 20110312090000 -p TEXT -h /usr/local/oracle/10.2.0-64

脚本：

#!/usr/bin/bash
# ********************************
# * dba_oracle_awr.sh
# ********************************
# Usage: dba_oracle_awr.sh -s [instance_name]
#          -f [from time]
#          -t [to time]
#          -p [report type, html or text]
#          -h [oracle home]
#          -n [tns admin]
#
#         time format: 'yyyymmddhh24miss'.
#         E.g 20110304170000 means 05:00:00pm, Mar 04, 2011
