You need to install and configure an SNA communications server,
such as IBM® Communications Server. To set up
communication over SNA define the following in your SNA communications product.
- The local node characteristics that are common to all SNA users
at the workstation.
- A local logical unit (LU) for the CICS® Universal Client.
- A partner logical unit for each CICS server
with which the CICS Universal Client will
communicate.
- One or more modes to specify sets of session properties that are
used in binding SNA sessions.
- A transaction program (TP) for
the CRSR transaction. You need this if the following apply:
- The CICS servers
support terminal emulation, and
- You require automatic transaction initiation (ATI) against the CICS Universal Client terminals.
The terms used to describe these definitions vary with the product used
to provide support. The terms used above are the ones used by IBM Communications Server.
SNA links to the CICS Universal Client support
data synchronization levels (sync levels) 0 and 1.
