Coding the gateway path

The GWPATH definition statement is required for all gateway VTAMs that initiate cross-network SSCP-SSCP sessions. If you do not code GWPATH definition statements following a CDRM definition statement for a VTAM® in another network, code the SUBAREA operand on that CDRM definition statement so that VTAM can determine the gateway NCP to use.

Dynamic cross-domain resource definition must be allowed for the host CDRM if the NetView® alias name translation facility or the alias function in the session management exit is used to translate logical unit names.
