1，登錄oracle服務端
2，切換至oracle用戶
su - oracle
3，多實例需要切換至對應實例
3.1.查看實例方法如下
oracle@db02[/app/oracle]$ps -ef|grep smon
oracle 54102 1 2 Dec24 ? 02:32:00 ora_smon_aaaa
grid 144900 1 0 Dec13 ? 00:00:18 asm_smon_+ASM
oracle 145532 1 0 Dec13 ? 00:01:23 ora_smon_bb
oracle 179758 179473 0 10:08 pts/1 00:00:00 grep --color=auto smon
3.2.比如此次導出的awr報告爲bb，則切換實例至bb
export ORACLE_SID=bb
4.以管理員用戶登入數據庫
sqlplus / as sysdba
5，執行如下命令@?/rdbms/admin/awrrpt.sql
SQL> @?/rdbms/admin/awrrpt.sql
