Hp Ux 11.0 system node name

[Media_Frozen]

Hi Guys,

Currently i'm using hpux 11.0 on n4000 server, i need to change my system nodename/hostname from the maximum of 8 bytes to something bigger as required by the application team, do i need to download any patches for this?How do i change the
maximum of 8 bytes to accommodate longer system node name?

Any patches to be installed into the system or the patches is for rectifying problem that will arise from changing the node name?

According to the link posted above you should forget about changing anything.
There is a difference between host- and notename. hostname can only be 8 chars long.
If you want have problems, play with this.
If you DONT want to have problems - change nothing.

Remember, you are running an UNSUPPORTED version of hp-ux since 1 year. (11.00).

Yes, i knew it would cause problem but the application team is insisting that their application need this to work.I would have to convince them by testing it in dev server first and show to them the amount of problem it would caused if we actually went ahead with the patches. So my question still stand, do i have to download any patches for this? I mean to enable node name to be greater than 8 bytes.

I don't think so. As mentioned, you are hosed either way, so change it and test it. Read the other thread carefully, and TG's link.

There are two network names in HP-UX: nodename and hostname. Normally, they are the same. The man page for hostname explains the differences. The startup variable NODENAME is the UUCP name which is returned by uname -n, while the HOSTNAME variable sets the networking (ARPA, NFS, etc) name, which can be 64 chars long (see /usr/include/sys/param.h for MAXHOSTNAMELEN). HOSTNAME can be much longer than 8 characters BUT only if you define an 8-character or less NODENAME in the /etc/rc.config.d/netconf file, like this:

NODENAME=myhost08
HOSTNAME=myreallylonghostname

And of course for networking, the /etc/hosts file provides all the hostname aliases you might need -- assuming you put files then dns in /etc/nsswitch.conf.
