changing the em host/ip

Hello,

after testing a database, we have recently deployed it.  For the deployment, we changed the host name and ip.   We recreated the em repository for the new host name and ip.  The repository recreated fine, and we can log in.  However, on the home page it still displays the old host name and ip.  When trying to perform any of the functions,  it errors out because it doesn't recognize the host, since it's trying to access the old host.   Is there some other place where the host name needs to be changed?

thanks,

Rae
