Change forgotten password of the root user at the Linux server

Hi All,

Yesterday, i forgot root password for my hosting webserver. So I decided to crack it using the following steps. It’s documented and is written in the Linux manual


http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/step-guide/s1-q-and-a-root-passwd.html

And finally, i was able to login to my server.

Cheers!!!

Blocking developers from using TOAD and other tools on production databases

Today, I’ve seen a nice example at www.psoug.org on how to prevent users from using additional tools to connect to production database. This is the AFTER LOGON trigger create ON DATABASE as follows:

CONNECT / AS SYSDBA;
 
CREATE OR REPLACE TRIGGER block_tools_from_prod
  AFTER LOGON ON DATABASE
DECLARE
  v_prog sys.v_$session.program%TYPE;
BEGIN
  SELECT program INTO v_prog
    FROM sys.v_$session
  WHERE  audsid = USERENV('SESSIONID')
    AND  audsid != 0  -- Don't Check SYS Connections
    AND  ROWNUM = 1;  -- Parallel processes will have the same AUDSID's
 
  IF UPPER(v_prog) LIKE '%TOAD%' OR UPPER(v_prog) LIKE '%T.O.A.D%' OR -- Toad
     UPPER(v_prog) LIKE '%SQLNAV%' OR     -- SQL Navigator
     UPPER(v_prog) LIKE '%PLSQLDEV%' OR -- PLSQL Developer
     UPPER(v_prog) LIKE '%BUSOBJ%' OR   -- Business Objects
     UPPER(v_prog) LIKE '%EXCEL%'       -- MS-Excel plug-in
  THEN
     RAISE_APPLICATION_ERROR(-20000, 'Development tools are not allowed here.');
  END IF;
END;
/
