I totally agree. Our network is in a constant state of change, but our host
names change much less frequently. So I get to ignore most of the things
that change here. I doubt that there's any appreciable response time hit
either, because I would assume that the host-to-IP translation only is done
at channel start anyway.

Hi Kulbir,
IMO, you should always use DNS, and refuse to set up a channel connection
by IP address. Before we took this stand, we'd been bitten by folk out in
the 'Fischer Price' world changing the IP of a server and failing to notify
us. If they forget to have the DNS record changed, then it'll be picked up
in basic system testing.

Subject: Hostnames or IP addresses for channel connection names
Hi there,
We have a very large network of MQSeries installations (> 300
installations) that are currently using a mixture of Hostnames and IP
addresses for the channel connection names. We are in the process of
reviewing our configurations and will be looking to standardise the
use of the conname attribute, either go with Hostnames or IP
addresses.
Our gut feeling is to go with Hostnames as they are more descriptive
of what the channel is connected to and also gives us the flexibility
of being able to change IP addresses of machines without effecting
channel definitions. However, there are people in our team that seem
to suggest that using an IP address rather than a hostname would
significantly improve performance, is this true? I can believe that
there may be a difference in channel startup times but after that
there should be no difference, is this correct?
Which do people tend to use and why?
Thanks,
Kulbir.
