How to change global name to reflect a new host name?

Hello,
I restored hot backup on another NT server.
Here are changes I made to reflect a new host name:
db_domain & service_name in init.ora
SID_NAME and GLOBAL_DBNAME in listener.ora
HOST and SERVICE_NAME in tnsnames.ora

Everything works ok. The only place I see an old host
name is when I
select * from global_name

Is there any way to change domain part of global name
to specify a new host name?

Thanks
ninel
