Configure sysplex distributor tier 1 distributed DVIPAs and ports

Configuring sysplex distributor tier 1 distributed DVIPAs and ports in this scenario is similar to scenario 1. To review that information, see Configure sysplex distributor tier 1 distributed DVIPAs and ports.

In scenario 2, the group name GROUP1 is added, and the IP addresses of the DataPower® appliances in the DESTIP list are at two sites instead of one, as shown in the following example:

VIPADEFINE TIER1 255.255.255.0 10.91.1.1
VIPADISTRIBUTE DEFINE
   GRE DISTM TARGCONTROLLED
   TIER1 GROUP1
   CONTROLPORT 5601
   10.91.1.1 Port 8080
   DESTIP 201.81.10.1 201.81.10.2
          201.81.20.1 201.81.20.2

DISTMETHOD TARGCONTROLLED indicates that sysplex distributor and the DataPower appliances exchange information about the availability and capacity of the DataPower appliances. Sysplex distributor makes a load-balancing decision based on this information and, in this scenario, on the availability and capacity of the z/OS® server applications in application group GROUP1 on the CPC of each DataPower appliance. The group name is used when the tier 1 sysplex distributor gathers information from the tier 2 distributors about availability and capacity of z/OS server applications for a specific server group on that CPC.
