Host Enterprise Manager

Hello,
I have 1 node with a Oracle DB single instance in AIX 5L (64bits). When I created the DB I did put that it uses Enterprise Manager. The DB is created correctly. When I try access to EM, it shows well, I put user and password and it shows a error because the host is other ... Where may I configure (what file) for that it has the correct host? When I run "hostname", the output is correct, the /etc/hosts file is correct too. Thanks beforehand.

Cheers...
