自动生成awr报告shell脚本--每天早8点到晚12点每四个小时生成一次

一共两个脚本
生成脚本：dba_oracle_awr.sh
调用脚本：awr_everyday.sh

#!/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
