There is a choice of network protocols for connecting to CICS®.
Note: In these descriptions, the terms
"local mode" and
"remote
mode" refer to whether the connection between Client application
and Gateway uses a network connection. See the related topics for
more information on running in
local mode or
remote mode.
All protocols support ECI COMMAREA requests.

connections in a local mode (two-tier) configuration. IPIC also supports
the offload of work to a zSeries Application
Assist Processor (zAAP).
- EXCI

commit transactions.
