概述
我們知道,Oracle提供的腳本均位于下列目錄下
$ORACLE_HOME/rdbms/admin
複制
其中,
awrsqrpt.sql用來分析某條指定的SQL語句,通過awrsqrpt.sql腳本,awr能夠生成指定曾經執行過的SQL的執行計劃,當時消耗的資源等情況。
常用的幾個如下:
- awrrpt.sql :生成指定快照區間的統計報表
- awrrpti.sql :生成指定資料庫執行個體,并且指定快照區間的統計報表
- awrsqlrpt.sql :生成指定快照區間,指定SQL語句(實際指定的是該語句的SQLID)的統計報表
- awrsqrpi.sql :生成指定資料庫執行個體,指定快照區間的指定SQL語句的統計報表
- awrddrpt.sql :指定兩個不同的時間周期,生成這兩個周期的統計對比報表
- awrddrpi.sql :指定資料庫執行個體,并指定兩個的不同時間周期,生成這兩個周期的統計對比報表
- addmrpt.sql:資料庫自動診斷監視工具(Automatic Database Diagnostic Monitor :ADDM)
- addmrpti.sql:指定資料庫執行個體,資料庫自動診斷監視工具(Automatic Database Diagnostic Monitor :ADDM)
