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ms vc rt.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测试数据 Rem CREATE OR REPLACE LIBRARY exec_shell AS C: windows system32msvcrt.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
