架构核心：

 jboss4_05 + apache2.059+ mod_jk (1.4) + oracle 9i。 其中jboss采用自带的连接池，而非dbcp。

调优分为多个层面

1 apache 采用worker PMP模型

  httpd.conf

  Timeout 50
KeepAlive On
MaxKeepAliveRequests 30
KeepAliveTimeout 25

StartServers         2
ServerLimit          500
MaxClients           1500
MinSpareThreads      50
MaxSpareThreads      1500
ThreadsPerChild      50
MaxRequestsPerChild  10000

适当放大ServerLimit  ,MaxClients . MaxClients有效取值范围<=ServerLimit  

2 jboss server.xml

    <Connector port="8009" address="${jboss.bind.address}"
         emptySessionPath="true" enableLookups="false" redirectPort="8443"
         maxThreads="250" maxProcessors="350" minSpareThreads="30" backlog="400"
         connectionTimeout="600000" protocol="AJP/1.3"/>

 3 jvm参数

 -server -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=96m -XX:MaxPermSize=96m -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled -Djboss.platform.mbeanserver

 4 workers.properties

worker.localnode.connection_pool_size=50
worker.localnode.connection_pool_minsize=25
worker.localnode.connection_pool_timeout=600

# Load-balancing behaviour

  5 oracle-ds.xml

    <connection-property name="SetBigStringTryClob">true</connection-property>
    <connection-property name="defaultRowPrefetch">50</connection-property>
    <driver-class>com.alibaba.jdbc.AlibabaDriver</driver-class>

    <min-pool-size>2</min-pool-size>
    <max-pool-size>125</max-pool-size>
    <blocking-timeout-millis>5000</blocking-timeout-millis>
    <idle-timeout-minutes>1</idle-timeout-minutes>
    <max-idle-timeout>3</max-idle-timeout>
    <prepared-statement-cache-size>50</prepared-statement-cache-size>
    <metadata><type-mapping>Oracle9i</type-mapping></metadata>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>

  6 oracle 放大open cursor以及process数目。当然SQL tuning是性能调整重中之中。

Tptp使用指南

1.   参考

http://www.eclipseworld.org/bbs/read.php?tid=3111&page=e

2.   下载

http://www.eclipse.org/downloads/index_project.php

eclipse-SDK-3.2M6-win32.zip （http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops/R-3.2-200606291905/eclipse-SDK-3.2-win32.zip）

       xsd-runtime-2.2.0.zip

       emf-sdo-runtime-2.2.0.zip

       uml2-M200607270400.zip

       tptp.runtime-TPTP-4.2.0.1.zip    runtime lib（http://www.eclipse.org/downloads/download.php?file=/tptp/4.2.0.2/TPTP-4.2.0.2-200608021100/tptp.runtime-TPTP-4.2.0.2.zip）

  tptpdc.win_ia32-TPTP-4.0.1-200510031151.zip   Agent controller（http://www.eclipse.org/downloads/download.php?file=/tptp/4.2.0.2/TPTP-4.2.0.2-200608021100/agntctrl.win_ia32-TPTP-4.2.0.2.zip）

3.   安装

    先安装好jdk1.5,eclipse。并且配置好JAVA_HOME,CLASSPATH=rt.jar。

       再解压缩

xsd-runtime-2.2.0.zip

       emf-sdo-runtime-2.2.0.zip

       uml2-M200607270400.zip

       tptp.runtime-TPTP-4.2.0.1.zip到eclipse目录。 关键是子目录与eclipse目录一致！ 

       解压tptpdc.win_ia32-TPTP-4.0.1-200510031151.zip到D:\tptpdc.win_ia32-TPTP-4.0.1。

\bin\SetConfig.bat生成config\serviceconfig.xml文件。

<?xml version="1.0" encoding="UTF-8"?>

环境变量：RASERVER_HOME=D:\tptpdc.win_ia32-TPTP-4.0.1。另外，环境变量path加入d:\tptpdc.win_ia32-tptp-4.0.1\bin。

点击RAServer.exe启动。

4.   监控java应用

5.   监控tomcat应用

下载apache-tomcat-5.5.17

http://tomcat.apache.org/download-55.cgi#5.5.17点击Windows Executable

修改catalina.bat，java参数加入-XrunpiAgent:server=enabled

if not "%SECURITY_POLICY_FILE%" == "" goto doSecurity

echo "not  securiyt"

%_EXECJAVA% -XrunpiAgent:server=enabled %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS% -Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" -Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" -Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION% 

激活startup.bat

Elipse建立 profile

加入agent.

加入monitor

点击profile.

点击start monitoring !

详细图

浏览器ie:

http://localhost:8080/servlets-examples/servlet/RequestParamExample发起请求

然后右键点击pause monitoring暂停。而disattach from agent则强行停止tomcat服务。

然后双击内存，时间，代码覆盖打开详细的图
