proxool详细配置

   proxool一个数据库连接池框架，提供了对你选择的其它类型的驱动程序的连接池封装。可以非常简单的移植到现存的代码中。完全可配置。快速，成熟，健壮。可以透明地为你现存的JDBC驱动程序增加连接池功能。到目前为止最新版本是proxool 0.9.1,可从官网下载最新版本http://proxool.sourceforge.net

 

一、配置proxool.xml文件 

 

<?xml version="1.0" encoding="UTF-8"?>
    <!--
        the proxool configuration can be embedded within your own
        application's. Anything outside the "proxool" tag is ignored.
    -->
<something-else-entirely>
    <proxool>
        <alias>dbname</alias> <!--数据源的别名-->
        <driver-url>jdbc:oracle:thin:@127.0.0.1:1521:testdb</driver-url><!--url连接串-->
        <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> <!--驱动类-->
        <driver-properties>
            <property name="user" value="username" /> <!--用户名-->
            <property name="password" value="password" /><!--密码-->
        </driver-properties>
        <!--最大连接数(默认5个),超过了这个连接数,再有请求时,就排在队列中等候,最大的等待请求数由maximum-new-connections决定 -->
        <maximum-connection-count>100</maximum-connection-count>
        <!--最小连接数(默认2个)-->
        <minimum-connection-count>10</minimum-connection-count>
        <!--proxool自动侦察各个连接状态的时间间隔(毫秒),侦察到空闲的连接就马上回收,超时的销毁 默认30秒-->
        <house-keeping-sleep-time>90000</house-keeping-sleep-time>
        <!--没有空闲连接可以分配而在队列中等候的最大请求数,超过这个请求数的用户连接就不会被接受-->
        <maximum-new-connections>10</maximum-new-connections>
        <!--最少保持的空闲连接数(默认2个)-->
        <prototype-count>5</prototype-count>
        <!--在使用之前测试-->
        <test-before-use>true</test-before-use>
        <!--用于保持连接的测试语句 -->
        <house-keeping-test-sql>select sysdate from dual</house-keeping-test-sql>
    </proxool>
</something-else-entirely>

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

	</proxool>

二、配置web.xml
