【AWR】自動生成AWR報告指令碼以及用法

1，使用ftp工具上傳檔案autoawrrpt.sh到伺服器/home/oracle目錄

2，以Oracle使用者登入，修改shell指令碼執行許可權

[root@PrimaryDB oracle]# su - oracle

[oracle@PrimaryDB ~]$ chmod  755 autoawrrpt.sh

3，shell指令碼使用方法

./autoawrrpt.sh -s orcl -f 2013092917 -t 2013092918 -p HTML -h /home/ora11g/product/11.1.0

4，autoawrrpt.sh是附件shell指令碼

shell指令碼引數說明：

-f 2013092917   開始時間 格式年月日小時

-t 2013092918   結束時間 格式年月日小時

-p 格式 html或者是text

-h 環境變數ORACLE_HOME的值

-s 環境變數ORACLE_SID的值

5，使用瀏覽器開啟當前目錄下awr報告檔案，定位到SQL ordered by CPU Time部分分析

附autoawrrpt.shshell指令碼內容：

#!/bin/bash
# ********************************
# * autoawrrpt.sh
# ********************************
# Usage: autoawrrpt.sh -s [instance_name]
#          -f [from time]
#          -t [to time]
#          -p [report type, html or text]
#          -h [oracle home]
#          -n [tns admin]
#
#         time format: 'yyyymmddhh24'.
#         E.g 2011030417 means 05pm, Mar 04, 2011
