tomcat优化

1：hibernate.cfg.xml 连接池改为50 
<?xml version='1.0' encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC 
  "-//Hibernate/Hibernate Configuration DTD 2.0//EN" 
  "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd"> 

<hibernate-configuration> 
    <session-factory> 
        <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property> 
   <property name="connection.url">jdbc:oracle:thin:@127.0.0.1:1521:ora10</property> 
        <property name="dialect">net.sf.hibernate.dialect.OracleDialect</property> 
        <property name="connection.username">uuuuuu</property> 
        <property name="connection.password">pppp</property> 
        <property name="show_sql">false</property> 
        <property name="connection.pool_size">50</property> 
        <mapping resource="com/Person.hbm.xml"/> 

   </session-factory> 
</hibernate-configuration> 
2:编辑catalina.bat 
第一行加入SET JAVA_OPTS=-Xms850m -Xmx1300m 
注释掉 
rem set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG% 

 

3:catalina.bat第一行加入

SET JAVA_OPTS=-Xms850M -Xmx1300M -XX:PermSize=64M -XX:MaxPermSize=256m -Dcom.sun.management.jmxremote

这样可以使用jconsole查看内存

-Dcom.sun.management.jmxremote.port=8999
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
