SHELL版的自动批量生成AWR报告的脚本

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
