Configure a distributed DVIPA for the target z/OS application servers used by the group of DataPower appliances (optional)

The configuration of this distributed DVIPA has no special requirements; it is a normal distributed DVIPA that represents a cluster of z/OS® applications in the sysplex environment. Code VIPADEFINE, VIPABACKUP, and VIPADISTRIBUTE statements within the VIPADYNAMIC block of the TCP/IP profile using the normal options for z/OS applications.

Rule: Do not specify the CPCSCOPE, TIER2, and groupname parameters on these statements. These parameters are supported for DataPower® workloads; however, they have very specific configuration requirements and do not apply in this scenario.

In the following example, the DataPower appliances are all configured to send requests to IP address 10.81.1.1 and port 9001:

VIPADEFINE 10.81.1.1
VIPADISTRIBUTE DEFINE
    DISTMETHOD SERVERWLM
    10.81.1.1 Port 9001
    DESTIP ALL

These VIPADEFINE and VIPADISTRIBUTE statements are placed in the TCP/IP profile of one sysplex stack.

To configure the DataPower appliances to use the tier 2 distributed DVIPA and port when connecting to the z/OS application tier, see the DataPower documentation.
