The following TCP/IP and VTAM changes are needed to support HPR/IP (Enterprise Extender) connections. This procedure assumes you have z/OS and hardware on the mainframe to support Ethernet connections. These host changes are one time changes to your TCP/IP profile, VTAM startup, and XCA major node.
Define the VIPA device. When you configure BARR/RJE or BARR/NJE, this will match the Host name or IP address entered on the Link tab.

Specify the NETID. When you configure BARR/RJE or BARR/NJE, this will match the NETID entered on the Link tab.

SSCPID=06,NOPROMPT, |

Setup a major node for the XCA. Only one XCA definition with a Medium=HPRIP is allowed for a given VTAM. XCA connections are used as the path to connect the remote Barr Enterprise Extender node to VTAM. You can use Autogen to create dynamic PU’s for each connection.

If you are NOT using Autogen, define a switched Major Node with PU’s for each RJE or NJE that will be connecting using CP – CP sessions. When you configure BARR/RJE or BARR/NJE, this will match the CPNAME entered on the Link tab.
Because the sample VBUILD does not include a group, the XCA’s group is applied at connection initialization.
