Hi
Apologies if this should have been posted in an Oracle
/other lists.
Just bought a T5120 running Solaris 10 & a colleague
would like a temporary hostname be given to the host
& on the day this server goes live, change the hostname
to the ultimate production hostname.
Questions are :
Will changing hostname affect Oracle10g, Ssh, HP Data
Protector agent (/opt/aworks/agents/bin/hpaAgent) & a
Liebert UPS agent ("/opt/MultiLink/bin/LiebertM" daemon)
or do we need to reinstall these software after changing
hostname & IP addr?
The steps involved in changing hostname (excluding IP addr)
are quite tedious :
/etc/hosts (/etc/inet/hosts)
/etc/nodename
/etc/hostname.*interface*
/etc/net/ticlts/hosts
/etc/net/ticots/hosts
/etc/net/ticotsord/hosts
/etc/inet/ipnodes
/etc/nodename
and rename directory under /var/crash
# cd /var/crash
# mv oldname newname
Use "hostname newname" to change the hostname
on the fly (so don't have to reboot server).
My view is it's fair to use a temporary IP address (so tt
the old & new servers are on the same LAN for ease
of transferring files/data from old to new server) & on
the day of going live, change the IP addr to actual
production addr but my colleague still would like to use
a temporary hostname to avoid confusion (in case we
login to the wrong server).
Thanks for your inputs,
U
