說明：本文爲Oracle 11gR2中查看SQL的AWR報告的指導手冊
用途：本文只是提供一種方法和思路，更多更高級的使用方法還期待你不斷的探索哦
標籤：查看SQL的AWR報告、WORKLOAD REPOSITORY SQL Report、awrsqrpt.sql、awrsqrpi.sql
溫馨提示：如果您發現本文哪裏寫的有問題或者有更好的寫法請留言或私信我進行修改優化
★ 執行測試SQL
※ 溫馨提示：建議將測試SQL執行5次以上，否則AWR不會收集該SQL的信息
sqlplus / as sysdba
select /*tag zzt_005*/ *
from scott.emp e, scott.dept d
where e.deptno = d.deptno
and empno > 7800;
★ 手動生成AWR快照
BEGIN
DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;
/
★ 查看業務SQL信息（本例中SQL_ID：43c4xrbk0qdvc）
sqlplus / as sysdba
select * from v$sqlarea a where lower(a.SQL_TEXT) like '%/*tag zzt_005*/%';
★ 執行AWR腳本，查看特定SQL的AWR
@$ORACLE_HOME/rdbms/admin/awrsqrpt.sql 單實例
@$ORACLE_HOME/rdbms/admin/awrsqrpi.sql 自定義實例
具體使用方法：（略）
