Tomcat下Teradata的JNDI数据源配置
这里以tomcat-5.5.7为例，tomcat 6配置与这不一样。
1，先在tomcat-5.5.7\conf\server.xml的<Host></Host>中增加如下代码：
<Context crossContext="true" debug="5" docBase="F:\JAVA\FxycWorkSpace\groupkpi\WebRoot"
path="/groupkpi" reloadable="true">
<Resource name="jdbc/TeradataDSCIM"
type="javax.sql.DataSource" auth="Container"
driverClassName="com.ncr.teradata.TeraDriver" maxActive="100"
maxIdle="30" maxWait="10000" url="jdbc:teradata://数据库IP/TMODE=TERA,CHARSET=ASCII,CLIENT_CHARSET=cp936,DATABASE=sxedrm2"
username="数据库用户名" password="密码" />
</Context>
2.把数据库驱动包拷贝到\tomcat-5.5.7\common\lib目录下。
3.重启Tomcat，并用下面的文件进行测试。
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@ page language="java"%>
<%@ page import="java.sql.*" %>
<%@ page import="javax.sql.*" %>
<%@ page import="javax.naming.*" %>
<%@page import="com.teradata.db.DBQueryEngine"%>
<%
String jndi_name="java:comp/env/jdbc/TeradataDSCIM";
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception("No Context");
DataSource ds = (DataSource)ctx.lookup(jndi_name);
Connection conn = ds.getConnection();
DBQueryEngine dLocal = new DBQueryEngine();
dLocal.createConnection(jndi_name);
String Sql = "SEL DIM_VALUE_ID FROM TAP_C_GRP_DIM_VALUE WHERE PAR_DIM_VALUE_ID = '01' and STATISTICS_TYPE_ID = 1";
try{
dLocal.executeQuery(Sql);
while(dLocal.next()){
System.out.println(dLocal.getString(1));
}
}catch(Exception e){
}
