Requirement: 4 LPAR's defined. This user wants to run a the same server application on each LPAR. But he wants the users to use one IP address and it will always get one of the server applications.
What do you need to achieve? To me this sounds like 4 active copies of the application with load balancing. Sysplex distributor is the best answer for that. DNA round robin, as discussed, may give something similar but not as good. If you only want resilience you can use a DVIPA Use automation, or manual process, to ensure one and only one copy of the application is bound to a TCPIP stack. Have that active copy BIND to a DVIPA in a VIPARANGE. You may be able to use PORT BIND in the TCPIP profile. When that application closes the DVIPA is automatically deleted by the IP stack and you can start a new active copy with the same DVIPA elsewhere. Sysplex distributor is fairly simple to configure so I do not understand your reluctance to use it.

I cross posted the following to the TCP/IP group, but got no response. Thought I would try here to see if I get any answers. Thanks: I am trying to avoid setting up TCP/IP Sysplex Distributor to accomplish a certain task. But if it is the only way possible then I will do it. I have a CPU that has 4 LPAR's defined. This user wants to run a the same server application on each LPAR. But he wants the users to use one IP address and it will always get one of the server applications. Also if one LPAR is down he wants to make sure the other server will receive the request. So is there another way to accomplish this without using TCP/IP Sysplex Distributer?
