Hey,
you can't set a hostname that is more than 8 characters. Also try not using charachters like "-", because there are some programs that won't work (had this problem).

Piyut,

Ofcourse, Reboot is required.

some of the configuration do not need reboot. you can reinitialize them by re-running /sbin/rc. You can do this by first finding the run level you are currently in (use 'who -r').

$ who -r
run-level 3

$ /sbin/rc 3

Piyut,
A reboot is absolutely required to effect a change in host name. As for the commands to do that, its already been provided in the posts prior to mine.
As per the comments before mine, try to keep your hostname to 8 names and not to have any special chars...

Hi Piyut

Just to add my 5p worth, limit the hostname to 8 characters and don't forget to change /etc/hosts. If you don't, the server may have trouble booting and this will cause problems for SD (software distributor -swinstall etc.)/NFS applications.

One other thing, you can add at-sn-billing-05 to /etc/hosts (after the new 8 character hostname) so that the server still resolves this address internally, to itself.
