Dear VIPA Gurus,

   We are playing with dynamic VIPA and sysplex distributor on z/OS V1R13.  The 
Network guy is puzzled with some of this and I think I got enough information 
from him.  External users use the same VIPA to access our application no matter 
where it runs.  Application runs in one place at a time.  When the application 
started task tries to come up, it is "managed" by this "routing" thing  (the 
heart of the DVIPA and sysplex distributor management which runs on one of our 
LPARs).  The Network guy showed me some stuff on how he set this up on VTAM for 
TCP and IIRC he correlated the VIPA address with some kind of IP Address that 
wasn't the VIPA or the raw interface IP Address.


Q).  Should the application on the host side default to the IP Address of the 
stack, or should the application on the host side be configured with the DVIPA?

Q).  Would these IP Addresses that correlate to the DVIPA be used on the host 
side behind the "router"?  Would one of these addresses be what I should 
configure for our application with on the host side?

Q).  Any experiences anyone would like to share?


   Thank you,  Dave
