VTAM-to-VTAM channel connection

z/OS Communications Server: SNA Resource Definition Samples
SC27-3676-00

A channel-attachment major node is used to define a channel-to-channel adapter connection between two host processors. This connection can be provided by a 3088 or 3737 unit or by multiple channel adapters on a communication controller.

To define channel-to-channel adapter support, you must define two channel-attachment major nodes for each connection, one on each host. The definition must include the following definition statements:
  • VBUILD TYPE=CA
  • GROUP LNCTL=CTCA
  • LINE
  • PU

For more information about this type of connection, see the z/OS Communications Server: SNA Network Implementation Guide.
