Steve We recently did something similar and suffered somewhat on the MF due to TTL. If you rely on DNS, then switching the IP addresses are dependent on a thing called TTL (time to live). The Chinits (or should I say LE) will cache an IP address derived from a DNS for the length of time given by TTL. This TTL value is supposed to save cycles and time in having to go to the DNS every time you want to know what the IP address. It is common practice to set these TTL values to 12 hours or more. This means the Chinit will not let go of the old IP address until the TTL has expired or the Chinit has been recycled. There is a fair amount of information to be seen on this topic (TTL) by using www.google.com. Good luck.

While our host names (what we use in the channel definitions) are not changing our TCP/IP addresses are. Will my channels find the new IP addresses if I just stop and restart the channels or do I need to stop and restart the queue managers on the distributed side?
