SQL Profile 总结（四）--使用示例

前提：sql profile工具的相关视图

dba_sql_profile

10g: sys.sqlprof$attr  &  sqlprof$

11g: sys.sqlobj$data  &  sys.sqlobj$

1、主要完成四个示例，如下

  • 使用dbms_sqltune.import_sql_profile过程手工指定提示的方式，这种方式要求非常高（查询块名等），一般不会使用
  • 使用create_sql_profile.sql脚本固定内存中已经有的SQL的执行计划，通过指定sql_id
  • 使用create_sql_profile_awr脚本来还原AWR里面保存的SQL语句的执行计划（暂时没环境测试）...
  • 将提示集手工移入到另外一条SQL语句的sql profile中（通过move_sql_profile.sql脚本实现）；

三、使用create_sql_profile_awr脚本来还原AWR里面保存的SQL语句的执行计划（暂时没环境测试）...

四、将提示集手工移入到另外一条SQL语句的sql profile中（通过move_sql_profile.sql脚本实现）；方法如下：

1、执行一条与需要固定执行计划的SQL语句结构一致的语句

2、通过各种方法来实现将第一步运行的SQL语句，得到自己预期的执行计划（添加提示，修改参数等等）

3、通过这个语句运行产生的提示集合（v$sql_plan.other_xml列），来为需要固定的SQL语句创建sql profile从而固定执行计划

SQL Profile 总结（四）--使用示例的相关文章

SQL Profile 总结（一）

一.前提概述 在介绍SQL Profile之前,不得不说的一个工具就是SQL Tuning Advisor:这个工具是从Oracle 10g開始引入,它的任务就是分析一个指定的SQL语句,并建议怎样使用一些方法来提高指定语句的性能,比如:收集缺失的对象统计信息.或者收集过时的对象统计信息.创建新的索引.调整SQL语句结构.採用SQL Profile等等方式. 二.为什么SQL Tuning Advisor可以找出提高语句性能的方法? 这须要从SQL Tuning Advisor的工作原理開始说明

通过案例学调优之--SQL Profile

通过案例学调优之--SQL Profile 一.什么是SQL Profile(概要) SQL Profile在性能优化中占有一个重要的位置. MOS里这么描述SQL Profile: SQL Profile是10g中的新特性,作为自动SQL调整过程的一部分,由Oracle企业管理器来管理.除了OEM,SQL Profile可以通过DBMS_SQLTUNE包来进行管理. 查询优化器有时候会因为缺乏足够的信息,而对一条SQL语句做出错误的估计,生成糟糕的执行计划.而自动SQL调整通过SQL概要分析来

SQL中的四种语言DDL,DML,DCL,TCL

1.DDL(Data Definition Language)数据库定义语言statements are used to define the database structure or schema. DDL是SQL语言的四大功能之一.用于定义数据库的三级结构,包括外模式.概念模式.内模式及其相互之间的映像,定义数据的完整性.安全控制等约束DDL不需要commit.CREATEALTERDROPTRUNCATECOMMENTRENAME 2.DML(Data Manipulation Lang

SQL Profile 如何使用

这些文章是我从<基于Oracle的SQL优化> 书中找到的 可以参考一下我的实验过程 SQL Profile Oracle10G中的SQL Profile可以说是Oracle 9i中的Stored Outline的进化. Stored Outline能够实现的功能SQL Profile也完全能够实现. 与Stored Outline相比,SQL Profile具备如下优点: 更容易生成.更改和控制. 在对SQL语句的支持上做得更好,也就是说适用范围更广. 使用SQL Profile可以容易实现

Oracle 通过sql profile为sql语句加hint

sql profile最大的优点是在不修改sql语句和会话执行环境的情况下去优化sql的执行效率,适合无法在应用程序中修改sql时.sql profile最常用方法大概是:--创建产生sql tuning advisor任务DECLARE  tuning_task varchar2(100);  l_sql_id    v$session.prev_sql_id%TYPE;BEGIN  l_sql_id    := '6w02d3ggsj4xb';  tuning_task := dbms_sq

Oracle固定SQL的执行计划(一)---SQL Profile

我们都希望对于所有在Oracle数据库中执行的SQL,CBO都能产生出正确的执行计划,但实际情况却并非如此,由于各种各样的原因(比如目标SQL所涉及的对象的统计信息的不准确,或者CBO内部一些成本计算公式的先天缺陷等),导致有时CBO产生效率不高.甚至是错误的执行计划.特别是CBO对目标SQL所产生的初始执行计划是正确的,后来由于某种原因(比如统计信息的变更等)而导致CBO重新对其产生了错误的执行计划,这种执行计划的改变往往会导致目标SQL执行时间呈数量级的递增,而且常常会让我们很困惑:这个SQ
