Thanks sreddy!
But, I still have problem to connect to the OEM.
i created the repository. So, In Repository connection information, I typed username:sysman Password:oem_tempory_password,service:junghun:1521:orcl0. it looks like the repository was created without problem. However, when I try to open OEM again, it require Administrator and password. Although I tried several differents name and password, it didn't let me in. PLEASE HELP ME!!!!!
