# Simple Connection Line Driver Overview

The Entire Net-Work Simple Connection Line Driver provides communication between client applications that use Software AG's new e-business connections and Adabas databases running in mainframe (z/OS, ) and open systems environments. The new e-business connections make use of:

- an enhanced communication protocol provided by Software AG that links e-business applications with enterprise servers

- the Adabas Directory Server (ADI).

  Notes:

  1. Mainframe Entire Net-Work does not use the Directory Server directly. Instead, open systems Entire Net-Work open systems installations (version 7 and later) notify the mainframe node of the databases that Entire Net-Work 7 serves and the mainframe node then broadcasts this information throughout the network.
  2. Mainframe-to-mainframe connections are not allowed via the Simple Connection Line Driver (TCPX).

Software AG products that support the e-business communication protocol and the Adabas Directory Server currently include Tamino, Jadabas, Entire Net-Work 7 and any other product that transports client requests using Software AG’s ADALNKX module. The underlying transport mechanism is TCP/IP.

The Adabas Directory Server is a centralized component that provides all directory information required to communicate between clients and servers and eliminates the need for directory configuration files on every machine. The code for the Adabas Directory Server is included in the Entire Net-Work Client code available on Software AG's Empower. To use the Simple Connection Line Driver, you must have the Adabas Directory Server installed somewhere on your system. If you have already installed this code with another Software AG product, we recommend that you use the installed code, so that your organization uses only one shared Directory Server. For more information about the Adabas Directory Server, read Software AG Directory Server Documentation. The documentation for Entire Net-Work Client is included with its code on Empower.

When using the new Simple Connection Line Driver, mainframe Adabas conversion must be enabled for all the databases that will be called by requests coming through the driver. For information on enabling Adabas conversion, read Simple Connection Line Driver Prerequisites.

This document provides information for administrators responsible for configuring and running the Entire Net-Work Simple Connection Line Driver once Entire Net-Work is installed.
