new time synchronization server 2

[gatetec]

I have a new time synchronization server.
What chanfge do I need to make to let AIX nodes point to the time synchronization server?

thx much

Add yor new server IP to /etc/ntp.conf:
server XX.XX.XX.XX
Start xntpd subsystem:
startsrc -s xntpd
Add ntp to yor inittab:
mkitab ntp:2nce:'/usr/sbin/startsrc -s xntpd'

NTP has a lot of configuration options, have a look at:

I forgot, if the difference beetween the ntp server date and hour and the ntp client is too large, it won't synchronize, so it's better to sync the hour before starting the xntpd subsystem.
On the ntp client:
ntpdate XX.XX.XX.XX
Replace XX.XX.XX.XX with your ntp server address.

Just to add to MoreFeo comments above

Look at this link, I've been thru this and it was too simple to configure!

Well, in my case we've got the ntp servers on Solaris, and with the conf I've said above it's working great, no need to specify stratum, drift or anything else, but as I've said, and as you can see in Khalidas's links, ntp.conf has a lot more options you may need, and you may have to tune both the server and the clients.

Does this change require any downtime of the node or have any impact on apps on the nodes? Right now, the time is in sync w/o the new ntp server.

 

[khalidaaa]

No it doesn't need any downtime but if the application on that node is so sensitive to the time change then i advice you be careful with that!

It will take some time for the sync to happen between the master time server and the clients!
