在oracle 存储过程中，怎么执行bat文件

1. 授于test用户文件读写和执行命令的权限

SQL>exec dbms_java.grant_permission('TEST','SYS:java.io.FilePermission','<>','read,write,execute,delete');

SQL>exec dbms_java.grant_permission('TEST','java.lang.RuntimePermission','*','writeFileDescriptor' );

2. 建立java source

CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "bb" as import java.io.*;
import java.lang.*;
import java.util.*;
import java.sql.*;
import oracle.sql.*;
public class bb
{
public static void invoke_exe() throws IOException
{
Process p=Runtime.getRuntime().exec("d:/exp_74.bat");--注意/符号
try
{
p.waitFor();
}catch(InterruptedException ie){System.out.println(ie);}
}
}
/

3. 建立调用java source的存储过程CALL_BB

create or replace procedure CALL_BB
as
language java
name 'bb.invoke_exe()';
/

4. 执行CALL_BB即可；
