forget password for Oracle Enterprise Manager Application Server Control

Samer,

I have had the same thing in the past when I inherited an IAS installation and I resolved it by resetting the sysman password using the following from Oracle:

1.  When the Enterprise Manager (EM) OMS and Repository are new, the default EM
    Administrator account and password are:

       Name: sysman
       Password: oem_temp

During this first logon attempt to the EM Console, a security warning will be
displayed prompting for a change to the default sysman password.

2.  When the EM setup is not new and the account supplied in the logon window
    previously worked, try using a different EM administrator account.  If
    necessary, use the SYSMAN account and then reset the invalid username's
    password.  

Note: The administrator name is not case sensitive, however, the password is
case sensitive.

If oem_temp is no longer the password for SYSMAN and you need to reset the
existing password back to oem_temp, perform the following steps:


3.  Obtain the username/password of the EM Repository owner.  The username is
    normally stored in the omsconfig.properties file but the password is
    encrypted.

4.  Shutdown the OEM Console login dialog box.

5.  Shutdown the Oracle Management Server (OMS).
 
6.  Connect to the Repository database, where the EM Repository is stored.  
    Connect as the EM Repository owner using SQL*Plus Worksheet, and choose the
    option to "connect directly to a database" (or connect using SQL*Plus).
 
7.  Execute the following SQL statement:

       'execute smp_maintenance.reset_sysman();'

    For OEM 2.0.4 execute the script: vduResetSysman.sql, for example:
       csh% sqlplus repository_owner/password@mynode.world
       Sqlplus> @$ORACLE_HOME/sysman/admin/vduResetSysman.sql;

    Exit.

8.  Restart the OMS and start the OEM Console.

9.  Log in as the user SYSMAN and specify the password "oem_temp".
    Change the default password when you are prompted.


I hope that helps you.
