You can connect CICS® systems in a network in many
ways. If the data is successfully transferred in the correct format,
the CICS systems are unaware of the network makeup.
SNA configuration is performed at two levels:
- The logical level, which incorporates the characteristics
of the systems that want to communicate.
- The physical level, which incorporates the linking of actual
servers in the network.
The following tasks, Connecting at the logical level and Connecting at the physical level, describe
these connection levels in detail, and introduce you to the common
SNA terminology that is associated with them. Communicating across SNA connections discusses
communication across these connections.
