The Server Option runs on an IBM z/Series or plug-compatible mainframe computer. The Server Option uses either the Logical Unit 6.2 (LU 6.2) or Transmission Control Protocol/Internet Protocol (TCP/IP) communications protocol with a host transaction processor, such as CICS, as a communications front end.
The Server Option supports both three-tier (gateway-enabled) and two-tier (gateway-less) environments. When installing and using the Server Option, follow the instructions in this book for your environment.
