The Sysplex Distributor is useful when using IOAGATE in conjunction with Control‑D/Page On Demand for support of Control‑D/WebAccess. Control‑D/WebAccess can potentially have thousands of users in one Sysplex. The Sysplex Distributor enables you to distribute the load between multiple z/OS images, providing scalability, load balancing, and availability.

When you use the Sysplex Distributor with Control-D/WebAccess, define the following channel parameter in the CHANNEL declaration in the ECAPARM member:

BIND=DVIPA_address

Using the example as described in Sysplex environment requirements, the corresponding definitions for that example would be:

PORT=4000,

BIND=172.16.240.193

Note: You can use the BIND parameter of the TCP/IP Profile PORT statement to define IOAGATE support for this feature transparently, meaning, without setting the BIND parameter in IOAGATE.
