Open ServerConnect supports both three-tier (gateway-enabled) and two-tier (gateway-less) environments. It can receive requests from LAN clients through any of the following:
Transaction Router Service (TRS) or Net-Gateway using SNA or TCP/IP in a three-tier gateway-enabled environment
TCP/IP in a two-tier gateway-less environment
Adaptive Server Enterprise for server to server communication
If you use SNA as your protocol, use Online Transaction Processing (OLTP), or have large numbers of geographically-dispersed Adaptive Servers, you must use a TRS or Net-Gateway in a three-tier environment for routing.
For detailed information about compatibility, network
drivers,
new features in this version, performance factors, security, three-tier
and two-tier environments and how to install and configure Open
ServerConnect in both environments, see the Mainframe Connect Server
Option Installation and Administration Guide.
