Tomcat 連接池配置

Tomcat6.0連接池配置
  1.配置tomcat下的conf下的context.xml文件,在之間添加連接池配置: 
1.    <Resource name="jdbc/oracle"
2.           auth="Container"   
3.           type="javax.sql.DataSource"   
4.           driverClassName="oracle.jdbc.driver.OracleDriver "   
5.           url=" jdbc:oracle:thin:@host:port:databse"   
6.           username=" user "   
7.           password="password"   
8.           maxActive="100"   
9.           maxIdle="30"   
10.           maxWait="10000" />   
2.配置你的應用下的web.xml中的之間加入:
1.    <resource-ref>   
2.        <description>DB Connection</description>   
3.        <res-ref-name>jdbc/oracle</res-ref-name>   
4.        <res-type>javax.sql.DataSource</res-type>   
5.        <res-auth>Container</res-auth>   
6.      </resource-ref>   
3.把連接數據庫的第三方驅動放到common/lib下面就ok了
4.測試程序我就不寫了

Tomcat5.5x連接池配置

方式一、全局數據庫連接池
1、通過管理界面配置連接池，或者直接在tomcat\conf\server.xml的GlobalNamingResources中增加
<Resource name="jdbc/mydb" type="javax.sql.DataSource" password="mypwd" driverClassName="com.microsoft.jdbc.sqlserver.SQLServerDriver" maxIdle="2" maxWait="5000" validationQuery="select 1" username="sa" url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb" maxActive="4"/>
2、在tomcat\webapps\myapp\META-INF\context.xml的Context中增加：
<ResourceLink global="jdbc/mydb" name="jdbc/mydb" type="javax.sql.DataSource"/>
這樣就可以了。
方式二、全局數據庫連接池
1、同上
2、在tomcat\conf\context.xml的Context中增加：
<ResourceLink global="jdbc/mydb" name="jdbc/mydb" type="javax.sql.DataSource"/>
方式三、局部數據庫連接池
只需在tomcat\webapps\myapps\META-INF\context.xml的Context中增加：
<Resource name="jdbc/mydb" type="javax.sql.DataSource" password="mypwd" driverClassName="com.microsoft.jdbc.sqlserver.SQLServerDriver" maxIdle="2" maxWait="5000" validationQuery="select 1" username="sa" url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb" maxActive="4"/>
參數說明：
driveClassName：JDBC驅動類的完整的名稱； 
maxActive：同時能夠從連接池中被分配的可用實例的最大數； 
maxIdle：可以同時閒置在連接池中的連接的最大數； 
maxWait：最大超時時間，以毫秒計； 
password：用戶密碼； 
url：到JDBC的URL連接； 
user：用戶名稱； 
validationQuery：用來查詢池中空閒的連接。
以上三種方式在tomcat 5.5.4下都可以。另外，sql server的jdbc driver是從微軟網站上下載的sql server jdbc (sp3)。

tomcat5.0連接池配置
在tomcat 的下面路徑（Tomcat \conf\Catalina\localhost）下建一個xml文件，內容如下
 <Resource name="jdbc/test" auth="Container" type="javax.sql.DataSource"/>
    <ResourceParams name="jdbc/test">
        <parameter>

  41. </beans>  

注意上面要加上 
<property name="proxyTargetClass">  
     <value>true</value>  
</property> 
這段，都則會出錯。
