安装statspace

应用优化下面我们从技术的角度入手，来探讨数据库优化方面的问题。

通常作为优化Oracle系统的人，或者是DBA，其实很多时候对应用并不很了解甚至可以说是完全不了解，更不要说对应用程序代码的了解。

事实上呢，一个系统运行的快或者慢相信大家都明白，第一重要的是数据库的设计，然后是应用的设计， SQL 语句的编写，最后才是数据库参数的调整和硬件、网络的问题，等等。

所以在我们不了解一个系统的时候来优化数据库应用不是一个轻松的容易的事情。

那么我们第一步应该怎么做呢？通常有两类方法：其中一个方法就是我们常用的，使用statspack来进行诊断系统的瓶颈所在。

在statspack中oracle给出了几乎涵盖oracle大部分重要内容的信息。

另外一种方式，就是trace session。

假如某个session运行很慢或者某个用户的某个查询很慢，那么这个时候我们可以通过trace session的方式来诊断到底是慢在哪里，看究竟执行计划是怎样的，然后在user_dump_dest下根据该session的进程号或者线程号可以找到一个产生的trace文件。

通过使用tkprof格式化文件之后我们就可以看见很多的统计信息，这里包括了执行计划、parse/fetch等步骤消耗cpu的时间。

通常我们是观察query模式下的consistent gets来首先看sql是否使用了索引，然后看执行计划是不是正常，是不是有调整的余地。

当然如果您没有实际做过的话，这些内容说起来很抽象。

这是在不了解应用和程序下针对特定session的诊断和调整过程。

trace session的方式是一种自下而上的方法，从sql入手；而statspack是自顶向下的方法，也就是从宏观上先诊断数据库的瓶颈在哪里，然后从瓶颈入手来做调整，这个习惯上又可以称为通过等待事件（wait event）入手的方法。

2.1 使用statspackstatspack是一个性能诊断工具，首先发布于Oracle8.1.6版本，在8.1.7版本中功能得到加强。

Statspack&AWR 安装及使用

Statspack & A WR安装Statspack 1、在需要安装Statspack的数据库创建一个能容纳Statspack数据的表空间（至少120M）create tablespace statspackloggingdatafile'/u01/app/oracle/oradata/YJ/datafile/statspack.dbf'size 200mautoextend onnext 32m maxsize 1024mextent management local;2、安装脚本$ORACLE_HOME/rdbms/admin/spcreate.sqlSQL>@$ORACLE_HOME/rdbms/admin/spcreate.sql输入perfstat用户的密码perfstat选择statspack表空间选择TEMP临时表空间3、安装成功后用perfstat用户连接数据库connect perfstat/perstat搜集统计数据每一个统计信息的集合称为一个快照。

他们是一个时间点上通过v$视图获取的统计信息集合。

这个时间点上的统计信息的集合并被分配一个snap_id。

UTLBSTA T/UTLESTA T这个工具就是分析两张快照之间统计数据的变化。

STA TSPACK可以搜集您所需要的任何数量的快照，然后再生成报表来反映他们任意组合的情况。

注意：两个快照之间不能有数据库的关闭和重启的情况。

用perfstat用户建立快照SQL> exec statspack.snap查看快照建立是否成功select distinct snap_id from stats$waitstat;SNAP_ID----------1隔一段时间，产生新的应用后再次建立快照SQL> exec statspack.snapselect distinct snap_id from stats$waitstat;SNAP_ID----------12这时建立好了两个快照，就可以利用这两个快照生成报告了SQL>@/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/spreport.sql这样就能查看报告了！STA TSPACK的参数1、最经典的参数就是收集信息的等级，等级越高收集信息越详细，花费时间越长。

It will highlight the nodes through the color. It shows the modified Data Sources, Data Source Fields, LOVs, Data Blocks, Block Fields, Call forms etc in Blue Color. And it shows the newly added Data Sources, Data Source Fields, LOVs, Data Blocks, Block Fields, Call forms etc in Green Color.The main page of View changes looks like function generation page.Here in this page user is allowed to load a radxml. Then Workbench will show the all the changes done in the radxml across the release and release type accordingly with two different colors.Blue indicates modifiedGreen indicates new.So using View changes in Development Workbench, user can easily identify the changes done in the radxmls across releasesAcross the release and release type.3.1Process StepsThe starting page of the View changes will have only load button enabled and all the other buttons will be disabled at the beginning.4Fig 4.0 Development Workbench - View Changes link.Fig 4.2 Development Workbench - View Changes page.This page will allow user to load the radxml to view the changes in the radxml across releases and release types.Workbench allows viewing the changes done as part of Child or Cluster or Custom Release. Upon loading the Cluster or Custom or Child RAD xml, it shows the Modifications done as part Of Cluster or Custom or Child.5To load the radxml.Fig 4.3 View Changes - loading radxml.After loading the radxml one small window will pop up and will notify the details of the function id Like Function Type, Release Type.Figure notifies that changes done in the radxml as part of Cluster Release will be highlighted6Fig 4.4 View Changes – Notifying the release type in which changes done This will give brief details of what are the changes shown according to the release type. After loading the function id , Workbench will show the screen in the below format with blue andgreen accordingly.7Fig 4.5 Highlighting the Changes done in Cluster ReleaseThis will show the changes in the colors blue and green. Blue indicates modified and green indicates new, so in this function id.One data source is modified (in blue color) while one block is newly added (in green color) as part of cluster release4Change ReportChange Report allows us to view the changes in the provided base and source list of radxml’s, helps to get the changes done in the two radxml’s across releases and releasetypes.8View Changes Report allows the developer to see what exact change has been done in the radxml’s as part of the various nodes in the Development Workbench across two different releases or release types.It is generates reports based on two formatsComparison Types:1.Function specific: Compares Radxml’s Based on the function name2.Parent child: Compares Radxml’s Based on the parent child RelationThese are the nodes which are compared and report is generated based on the differences found in these below nodes of the two radxml’s given in the list Radxml’s.

Oracle SPARC T5-2服务器入门指南说明书

SPARC T5-2 Server Getting Started GuideThis guide describes how to install and power on Oracle's SPARC T5-2 server for the first time using the preinstalled Oracle Solaris OS.Before performing the procedures in this guide, review the following documents at the Oracle documentation web site: /goto/t5-2/docs.■SP ARC T5-2 Server Product Notes - For any late-breaking issues that impact installation requirements.■SP ARC T5-2 Server Installation Guide - For overview and more detailed installation information.■SP ARC T5-2 Server Safety and Compliance Manual - For safety and regulatory compliance information.For additional safety information, refer to the Important Safety Information for Oracle's Sun Hardware Systems, which is in the shipping kit.Shipping Kit1Server4Antistatic wrist strap2Cable management assembly (CMA)5Printed documents3Rackmounting kit6AC power cords (quantity 2)Install Optional ComponentsBefore installing the server into the rack, install any optional components you plan to use with the server that were not factory installed.For instructions on installing optional components, refer to the documentation for each component and to the SP ARC T5-2 Server Service Manual.Install the ServerFor quick installation and configuration, follow these steps. For more detailed information, refer to thecomplete online product documentation set.Caution - Do not apply power until instructed to do so. This server includes a service processor (SP) that configures and boots the host server. To properly configure the host server and view SP messages, do not apply AC power to the server until you make the SP and host networking connections, as described in this guide.1.Place the server in its intended location.For rackmounting and CMA instructions, refer to the SP ARC T5-2 Server Installation Guide.2.Connect a serial cable between the server's SER MGT port and a terminal device.This connection provides the initial communication with the SP. Set up the server to communicate using 9600 baud, 8 bit, no parity, 1 stop bit. For DTE-to-DTE communication, use a RJ-45 cable that is set up for a null modem configuration, in which the transmit and receive signals cross over.3.(Optional) Connect an Ethernet cable between the server's NET MGT port and the networkto which future connections to the SP and host will be made.Configure the server for the first time through the SER MGT port. After the initial configuration, you can set up communication between the SP and host through this Ethernet interface.4.Connect an Ethernet cable between one of the server's NET ports and the network to whichthe server will communicate.5.Connect the power cords to the power supplies and to separate power sources.The server is equipped with two power supplies. Connect them to separate power sources (200 to 240 V AC) to provide power redundancy. The server can operate with one power connection, but having only one power source reduces the redundancy.When the power cords are connected, the SP initializes and the power supply LEDs illuminate. After afew minutes, the SP login prompt displays on the terminal device. At this time, the host is not initialized or powered on.Power On the ServerThe following section describes how to power on the host after installing the server.1.At the terminal device, log in to the SP as root with a password of changeme.After a brief delay, the Oracle Integrated Lights Out Manager (Oracle ILOM) prompt (->) is displayed.For optimal security, change the root password. For more information about administration tasks such as changing passwords, adding accounts, and setting account privileges, refer to the SP ARC T5 Series Servers Administration Guide and the Oracle ILOM documentation at: /goto/ilom/docs By default, the SP is configured to use DHCP to obtain an IP address. If you plan to assign a static IP address to the SP, refer to the SP ARC T5-2 Server Installation Guide for instructions.2.Power on the server and redirect the host output to display on the serial terminal device.-> start /SystemAre you sure you want to start /System (y/n)? y-> start /HOST/consoleAre you sure you want to start /HOST/console (y/n)? ySerial console started.. . .Server initialization takes several minutes to complete.To cancel the server initialization, press the #. (Hash+Dot) keys to return to the Oracle ILOM prompt. Then type: stop /SystemNote - To use an OS other than the preinstalled version, refer to the SP ARC T5-2 Server Installation Guide.3.(Optional) Execute other Oracle ILOM commands while the server initialization continues inthe background.a. To display the Oracle ILOM prompt, press the #. (Hash+Dot) keys.b. To see information about available Oracle ILOM commands, type: helpTo see information about a specific command, type: help command-namec. To return to displaying host output from the server initialization, type: start /HOST/console4.When prompted, follow the onscreen instructions and type the configuration information foryour server.If you are not sure how to respond, accept the default and make changes later when the Oracle Solaris OS is running.

关于statspack以及awr使用

关于Statspack,AWR以及ASH使用Statspack部分Statspack是Oracle 8i以后提供的一个非常好的性能监控与诊断工具。

在数据库管理中，Oracle提供的statspack是一个很强大的工具，通过Statspack，可以收集系统信息，诊断数据库故障，也方便第三方技术支持进行远程阅读和建议。

Oracle Statspack 从Oracle8.1.6开始被引入Oracle,并马上成为DBA和Oracle专家用来诊断数据库性能的强有力的工具。

在oracle10g中被awr取代。

通过Statspack我们可以很容易的确定Oracle数据库的瓶颈所在，记录数据库性能状态。

因此了解和使用Statspack对于DBA来说至关重要。

Statspack的脚本位于$ORACLE_HOME/rdbms/admin目录下。

第一部分statspack安装以及卸载Statspack安装安装statspack至少需要100M表空间，如果需要长期监控，这个表空间应该设置的大一些。

Statspack相关数据不要放到system表空间。

在官方文档中明确指出在system表空间中不支持。

Statspack安装脚本位于:Unix：$ORACLE_HOME/rdbms/admin/spcreate.sqlWindow:%ORACLE_HOME%\rdbms\admin\spcreate.sql下面就以window下安装为例子介绍下statspack的安装过程以及出现问题如何处理：首先执行%ORACLE_HOME\rdbms\admin\spcreate.sql然后会提示你输入perfstat用户密码，指定默认表空间以及temporary表空间：下面白色部分已经明确指出system表空间不支持。

检查当前目录下spcusr.lis，spctab.lis和spcpkg.lis这三个文件，这三个文件记录安装过程所有记录，如果有问题可以使用%ORACLE_HOME\rdbms\admin\spdrop.sql删除后再重新安装1. spcusr -> 建用户和授予权限2. spctab -> 建表同义词索引等记录3. spcpkg -> 建包记录在unix下也可以用batch模式安装：SQL> connect / as sysdbaSQL> define default_tablespace='perfstat'SQL> define temporary_tablespace='temp'SQL> define perfstat_password='perfstat'SQL> @?/rdbms/admin/spcreate.sqlSQL> undefine perfstat_passwordstatspack的卸载Statspack卸载脚本位于:Unix：$ORACLE_HOME/rdbms/admin/spdrop.sqlWindow:%ORACLE_HOME%\rdbms\admin\spdrop.sql下面以window下卸载为例子介绍下statspack的卸载：执行%ORACLE_HOME\rdbms\admin\spcreate.sql执行完毕后，它会提示你去检查当前目录下的spdusr.lis和spdtab.lis文件Statspack数据清理（清理全部数据）当存放statspack的表空间快满的时候需要我们去清理表空间，操作如下：Statspack清理脚本位于:Unix：$ORACLE_HOME/rdbms/admin/sptrunc.sqlWindow:%ORACLE_HOME%\rdbms\admin\ sptrunc.sql下面以window下清理为例子介绍下statspack数据清理：执行%ORACLE_HOME\rdbms\admin\ sptrunc.sqlStatspack数据清理（清理指定数据）当存放statspack的表空间快满的时候需要我们去清理表空间，操作如下：Statspack清理脚本位于:Unix：$ORACLE_HOME/rdbms/admin/sppurge.sqlWindow:%ORACLE_HOME%\rdbms\admin\ sppurge.sql下面以window下清理为例子介绍下statspack数据清理：执行%ORACLE_HOME\rdbms\admin\ sppurge.sql下面会列出能清理的相关时间收集的统计信息：下面提示你输入开始和结束时间点，我们上面的是6，7，8，9，这四个数字代表相应时间，我执行这四次操作是连续做的，时间看起来不明显。

Oracle Sun Blade Storage Module M2 首次安装、启动和配置指南说明书

This guide describes the minimum steps you must perform to install,power on and configure Oracle’s Sun Blade Storage Module M2for the first time.Detailed installation information can be found in the Sun Blade Storage Module M2Installation Guide ,which isavailable on the Oracle web site:/docs/cd/E19452-01/index.htmlRefer to the section ”Documentation for This Product”at the end of this document for a complete list of documentation for this product.Contents■Storage module (SAS-2compliant storage)■Documentation■Antistatic wrist strap (required for installing optional components).Purchased separatelySafety and Compliance InformationBefore performing an installation,refer to the following documents for safety information regarding the Sun Blade Storage Module M2:■Important Safety Information for Sun Hardware Systems –Printed document included in the ship kit.■Sun Blade Storage Module M2Safety and Compliance Manual –Available online on the Oracle web site.Install Optional ComponentsBefore installing the storagemodule into the blade chassis,first install any optional components that you ordered with the storage module,such as drives.Unless specified otherwise,only SAS-2storage devices are supported in the Sun Blade Storage Module M2.Refer to the Sun Blade Storage Module M2Service Manual formore information on installing optional components.Sun Blade Storage Module M2Getting Started GuideConﬁrm a Supported Hardware EnvironmentThe Sun Blade Storage Module M2supports SAS-2.To achieve maximum 6Gb/s performance with SAS-2,all components that make up the chassis SAS-2fabric (server modules,REMs,NEMs,chassis)must support SAS-2.Note –Servers with a SAS-1REM can access their own internal disks and the network portion of the NEM,but cannot access the chassis SAS-2fabric.SAS-1disk blades are not supported in the chassis SAS-2fabric.At the release of this document,the Sun Blade Storage Module M2is supported in the following hardware environment (refer to the storage module documentation on the Oracle web site for up-to-date information).Note –The Sun Blade T6320and T6340server modules are supported for use in the chassis SAS-2environment with a SAS-2REM,but are limited to a maximum 3Gb/s data transfer speed.For an updated list of all compatible hardware that can be used with the storage module,refer to the Sun Blade Storage Module M2Product Notes.Supported Sun BladeServer Modules Supported SAS-2RAID Expansion Modules (REM)Supported Blade ChassisSupported SAS-2Network Express Modules (NEM)Sun Blade T6320(SPARC),with systemfirmware 7.2.8or later.See note below .•Sun Storage 6Gb SAS REM HBA (SGX-SAS6-REM-Z)•Sun Blade 6000Modular System with PCIe 2.0midplane (minimum CMM ILOM firmware required is 3.0.10.15a,included

ILOMfirmware required is 3.0.10.15b,included in chassis softwarerelease 3.2.2)▼Insert the Storage Module Into the Blade Chassis1.Ensure that your hardware environment supports SAS-2,as described in the previous section.2.If not already done,power on the blade chassis.3.Find a free blade chassis slot and remove the slot filler panel.To maintain proper cooling,install the storage module within 60seconds of removing the filler panel.4.Insert the storage module into the chassis as shown in the following illustration.The storage module can be installed in any free chassis slot.Chassis power will immediately be applied to the storage module.The following power-on sequence will take place:■The storage module green activity LED will blink and then remain steady on as the module is initially discovered by the Chassis Monitoring Module (CMM).■Full discovery of the storage module resources by the CMM can take 3to 5minutes.After full discovery,an “added to SAS-2fabric”event will be added in the CMM Integrated Lights Out Manager (ILOM)event log for the storage module and each of its drives.At this point,you can assign storage module resources to hosts as described in the ”Assign Storage Module Resources”section.Note –A host server module’s REM will not be able to see storage module resources until those resources are assigned on a per-host basis using the Sun Blade Zone Manager feature of the CMM ILOM.Check Storage Module StatusCheck to ensure the storage module is powered-on and that there are no faults.The green storage module activity and disk drive activity LEDs (shown below)should be steady on.Figure Legend1Insert into empty slot.2Push in to engage backplane connection.3Rotate ejectors until they snap into place.4Storage module should be flush withchassis.If you see an amber fault LED,do the following:■For a module fault,try removing and reinstalling the storage module.■For a single disk fault,try removing and reinstalling the disk drive.■For a multiple disk fault,try removing and reinstalling the storage module.Additional event information can be obtained through the CMM ILOM.For more on troubleshooting and servicing your storage module,refer to the Sun Blade Storage Module M2Administrator Guide and the Sun Blade Storage Module M2Service Manual .Upgrade FirmwareOracle recommends that you upgrade your chassis CMM ILOM,SAS-2NEMs,server module REMs,and storage module firmware to the latest version.This will help ensure compatibility with all installed components.To determine the firmware version of chassis devices,login to the CMM ILOM and view the CMM components.For a REM,launch the REM’s BIOS configuration utility available during server boot.For Sun Blade systems,firmware is available as part of a software release for the individual blade product and is posted on the Oracle site (/goto/blades ).More about upgrading storage module firmware can be found in the Sun Blade Storage Module M2Administrator Guide .▼Assign Storage Module ResourcesBefore a host server module can see storage module resources,you must run the Sun Blade Zone Manager from the CMM ILOM to assign storage resources on a per-host basis (this process is also called zoning ).Storage module resources can be assigned to either one host,or divided among several hosts.The blade chassis SAS-2fabric must be fully established and discovered by the CMM.This means that the components that make up the SAS-2fabric (SAS-2NEMs,server modules with SAS-2REMs,and storage modules)must be online with no faults.CMM discovery of storage modules and devices in the chassis can take three to five minutes.Figure Legend1Locate LED button.2Not used.3Module fault LED.4Module status LED.5Disk drive activity LED.6Disk drive fault/locate LED.7Disk drive ready-to-removeLED.1.Log in to the chassis CMM ILOM.You can use either the CMM ILOM web interface(described here),or the CMM ILOM CLI.Both methods are described in the Sun Blade Storage Module M2Administration Guide.2.Select CMM from the left pane and then select the Storage tab.3.Check the Enabled box[see1]for the Sun Blade Zone Manager and then click Save.4.Assign storage module resources to hosts using either the Quick(template-based)or Detailed(customized)setup option[see2]of the Sun Blade Zone Manager.The Sun Blade Zone Manager provides a graphical configuration of the chassis with supported servers and storage modules.Each participating host has its own assignments(called a zoned group).During the assignment process,each group(host and assigned storage)is assigned a unique color[see3].For detailed information on assigning storage module resources to hosts,refer to the Sun Blade Storage Module M2 Administration Guide.Note–Host-to-storage assignments are not complete until you click Save and all affected devices display a green check mark.The configuration window must remain open until this process completes.5.Log out of the CMM ILOM and access the console of a host to which you have assigned storage moduleresources.6.Confirm that assigned storage module resources are discovered and available to the host(a rescan usingthe REM software or a server reboot might be required).If your chassis has two SAS-2NEMs,storage module SAS-2drives will support dual path.7.Create your disk volumes using utilities supported by your server’s REM.For more information on creating volumes,refer to your REM documentation.Install the Operating System and Storage Management SoftwareFor a list of supported operating systems,see the Sun Blade Storage Module M2Installation Guide.For more about storage management options(such as RAID support and storage module monitoring),see the Sun Blade Storage Module M2Administration Guide and your REM documentation.Documentation for This ProductThe following table lists the documentation in the approximate order of the tasks that you might perform when installing a new system.Review the tasks on the left,then refer to the corresponding documentation on the right.You can find the most up-to-date versions of all the documents on the Oracle web site: /technetwork/documentation/oracle-blade-sys-190001.htmlFor translated versions of the documentation,go

swingbench OracleRAC11g使用方法图解

Swingbench for oracleRAC使用方法图解1 Swingbench 简述1.1 概述这是Oracle UK的一个员工在一个被抛弃的项目的基础上开发的。

目前稳定版本2.2，最新版本2.3，基于JDK1.5。

该工具是免费的，可以在作者的网站上自由下载，并且拥有详细的使用文档。

除了Swingbench，作者还开发了两个相关工具：测试数据生成工具DataGenerator 和跟踪文件分析工具Trace Analyzer。

Swingbench 可以执行4种不同的标准测试(benchmark)，拥有三种前端展示方式Swingbench/Charbench/Minibench，其中Charbench是字符模式的，另外两种是GUI模式的。

另外还可以通过ClusterOverview可以聚合显示所有的结果。

Swingbench 的开发目的主要是用来展示RAC的负载和测试，但也可用于单实例环境。

最新的2.3版本开始支持TimesTen 内存数据库。

下载地址：/downloads.html作者博客：/blog/blog.html目前网络上开源的oracle压力测试工具主要是orabm和swingbe nc h,由于orabm不支持oracle 11g版本，因此本次测试使用了swingben进行了压力测试。

另外，swingbench还能对rac进行测试。

swingbench是UK ba sed oracle Database Solutions group开发的一个oracle压力测试工具，好像是官方废弃的一个项目，官方页面/swingbench.html 上可以下载最新的软件版本。

swingbench可以运行在windows和linux平台，本次以windows 为例。

2. 环境配置测试客户端需要安装JDK，无需安装oracle client端swingbench的版本为2.4 ,直接解压软件压缩包，解压后路劲如下，因是windows下做测试所以使用 winbin目录下的批处理文件主要使用到的是如下四个bat文件主要的bat文件作用如下：1、bmcompare 用来对比测试结果2、ccwizard 是以CC种子为模板创建的运行测试数据3、clusteroverview 用来启动集群的压力测试，并查看测试结果4、coordinator 用来启动协调服务器5、minibench 用来注册节点到协调服务器6、oewizard 是以OE种子为模板创建运行测试数据7、shwizard 是以SH种子为模板创建运行测试数据8、swingbench 执行基准测试3.测试3.1 创建测试数据swingbench不使用客户数据，而是按自己的规则创建测试数据，（生成的测试数据只能使用一次，测试过后需要再次测试的话，需要重新创建测试数据，这点做的不好）到目标目录下运行oewizard.bat批处理文件，也可以在目录下双机oewizard.bat批处理文件运行会看到如下界面下一步下一步，输入你需要测试的数据库的 //ip/sid 以及sys用户的密码下一步，前三项不需要修改，为swingbench自动创建的schema，只需要修改datafile的存放路径即可。

Oracle性能分析工具Statpack安装使用详解文件版本：V1.0文件编号：发布日期：2015-03-05编制：程万超审核：批准：修订记录：修订版本号修订人修订日期修订描述V1.0程万超2014-12-17新建简介Oracle Statspack 是用来诊断数据库性能的强有力的工具，通过Statspack 我们很容易的确定Oracle的所有瓶颈，记录数据库的性能状态。

安装步骤一、Statpack原理：1.运行oracle自带脚本，生成一系列的统计表。

2.生成快照，采样。

3.根据快照生成报告。

二、安装准备1.检查部分参数值--job_queue_process:取值范围为0到1000，总共可创建多少个job进程，为了能够建立自动任务，执行数据收集，此参数大于零alter system set job_queue_processess=6;---timed_statistics，设置为true，使收集的时间信息存储在V$sessstats和V$sysstats等动态性能视图中，但会消耗资源，可以在使用Satspack之前设为true，采样过后，把该参数动态修改为false.alter system set timed_statistics=true;2. 脚本使用此功能，需要运行oracle自带脚本，在数据库中生成一系列的表和视图，用于收集各种信息。

脚本位于%oracle_home%\rdbms\admin(224数据库的该目录为/oracle/app/product/10.2.0/Db_1/rdbms/admin)目录下，oracle816下是一组以stat开头的文件，以后的版本是一组以sp开头的文件。

三、安装1.shell中切换到oracle用户：su - oracle2.以sysdba身份登录sqlplus。

9i及以后版本，可以用sys用户以sysdba身份登录：sqlplus / as sysdba(最好转到脚本所有目录%oracle_home%\rdbms\admin，便于执行脚本)3.创建表空间，用于保存采样数据create tablespace perfstat datafile '/oradata/xdgl/perfstat.dbf（表空间存储路径）' size 100m;Statspack的报表数据还是相当占空间的，特别是在多次连续采样的情况下，所以不能太小，最小100M，否则创建对象会失败。

查询表空间：select file_name from dba_data_files;4.运行脚本，安装statspack在sqlplus中执行命令：@%oracle_home%\rdbms\admin\spcreate.sql--脚本会创建用户perfstat，需要指定此用户密码。

输入perfstat_password 的值: perfstat--需要输入用户perfstat使用的表空间：指定新建的表空间即可。

输入default_tablespace 的值: perfstat--需要指定用户perfstat使用的临时表空间。

输入temporary_tablespace 的值: tmp10--安装成功，可以看到如下信息：Creating Package STATSPACK...程序包已创建。

没有错误。

Creating Package Body STATSPACK...程序包体已创建。

没有错误。

NOTE:SPCPKG complete. Please check spcpkg.lis for any errors.--查看错误信息NT下：host find "ORA-" *.LIShost find "err-" *.LISUnix下：grep ORA- *.lisgrep err *.lis如果出现错误，可以运行脚本删除相关内容：@%oracle_home%\rdbms\admin\spdrop.sql (注意：也要在sysdba下运行脚本删除相关对象)然后再重新运行脚本安装。

这个安装过程创建了一系列的表，用于存入采样数据。

查看新建表：select dt.table_name from dba_tables dt where dt.owner='PERFSTAT'conn perfstat/perfstatselect table_name from user_tables;安装完成后，系统会自动切换到perfstat用户下。

四、测试statpack运行statspack.snap可以产生系统快照，运行两次，产生两次快照。

SQL> execute statspack.snap;PL/SQL 过程已成功完成。

然后执行脚本@%oracle_home%\rdbms\admin\spreport.sql就可以生成基于两个时间点的报告。

--需要输入起始快照ID和结束快照ID，以及报告文件名。

(快照ID必须存在)Specify the Begin and End Snapshot Ids~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~输入begin_snap 的值: 1Begin Snapshot Id specified: 1输入end_snap 的值: 13End Snapshot Id specified: 13输入report_name 的值: e:\s1report.txt--查看产生的快照select t.snap_id,to_char(t.snap_time,'yyyy-mm-dd hh:mi:ss') as S_Time,t.snapshot_exec_time_s from STATS$SNAPSHOT t;五、规划自动任务安装之后，我们就可以设置定时任务，定时采样，收集数据。

使用脚本spauto.sql来定义自动任务。

spauto.sql在关键内容：beginselect instance_number into :instno from v$instance;dbms_job.submit(:jobno, 'statspack.snap;', trunc(sysdate+1/24,'HH'), 'trunc(SYSDA TE+1/24,''HH'')', TRUE, :instno);commit;end;执行spquto，就建立了一个每小时执行一次的数据收集计划。

这个Job任务定义了收集数据(执行statspack.snap)的时间间隔为1小时：一天24小时，1440分钟-->1/24,'HH' 每小时一次1/48,'MI' 每半小时一次1/144,'MI' 每10分钟一次1/288,'MI' 每5分钟一次关于采样间隔，通常建议1小时，如有特殊需要，可以设置更短，如半小时。

但不推荐更短。

因为statpack的执行本身需要消息资源，太短的采样对系统的性能会产生较大的影响(甚至会使statspack的执行出现在采样数据中)六．生成报告同测试一样用perfstat用户连接执行脚本%oracle_home%\rdbms\admin\spreport.sql，输入起始快照ID和结束快照ID，以及报告文件名，生成statspack报告。

注：一次statspack报告不能跨越一次停机，但是之前或之后的连续区间，收集的信息依然有效，你可以选择之前或之后的采样生成report.如果中间停过机，会收到以下错误信息：第 1 行出现错误:ORA-20200: The instance was shutdown between snapshots 1 and 31ORA-06512: 在line 48七、后续处理1，移除定时任务当你完成一个采样报告，你应该及时移除这个job任务。

遗漏一个无人照顾的job是非常危险的……--查看任务并移除任务select job, next_date, next_sec, what from user_jobs;execute dbms_job.remove('ID')2，删除历史数据1)，删除采样数据只要删除stat$snapshot数据表中的相应数据，其他表中的数据会相应的级连删除。

select max(snap_id) from stats$snapshot;delete from stats$snapshot where snap_id<=166;删除过程中，你可以看到所有相关的表都被锁定了。

select a.object_id, a.oracle_username, b.object_namefrom v$locked_object a,dba_objects bwhere a.object_id=b.object_id2)，truncate统计信息表：使用脚本sptrunc.sql删除所有的采样数据但保留statspack的库结构。

如果有大量数据，直接delete采样数据是非常缓慢的。

使用脚本sptrunc.sql可以快速的删除所有统计信息。

查看脚本，可以看出是用truncate table截掉所有相关的表中的内容。

truncate table STATS$FILESTA TXS;truncate table STATS$TEMPSTA TXS;...delete from STATS$DA TABASE_INSTANCE;3)，删除statspack所有数据和各种对象：使用脚本spdrop.sql。

全部删除，不留痕迹!但有表空间在~~八、调整statspack的收集门限statspack有两种类型的收集选项level--级别：控制收集数据的类型threshold--门限：设置收集的数据阀值都保存在表stats$statspack_parameter中1，级别(level)--有三种快照级别，默认值为5--查看当前level级别：select snap_level from stats$statspack_parameter;1)level=0：一般性能统计。

包括等待事件，系统事件，系统统计，回滚段统计，行缓存，SGA，会话，锁，缓冲池统计等等。

2)level=5：在level0的基础上，增加SQL语句的收集。

SQL语句收集结果记录在ststs$sql_summary表中。
