Entire Net-Work is the backbone of Software AG's distributed computing technology. It is middleware that provides a common communication service for database applications, query tools, cooperative processing applications, application development tools, and other software. Its primary function is to transmit Adabas calls from a client application to a remote Adabas database. However, it is also used by clients to access other Software AG product servers (such as those for EntireX Communicator, Tamino, or Adabas SQL Gateway).

In addition to Entire Net-Work for open system platforms (Windows and Linux), other versions of Entire Net-Work run on a range of hardware and software platforms including IBM mainframes. Using Entire Net-Work, organizations can implement applications distributed across multiple heterogeneous platforms.

Once you have installed the Entire Net-Work Client components, you must manually make updates in the Adabas Manager (AMN) if you need to support the Simple Connection Line Driver. For more information, read Required Post-Installation Updates for Simple Connection Line Driver Support.

Note
If you attempt to install and use Entire Net-Work in a system with a firewall in place, be sure that your system administrator has set up the firewall so that the Entire Net-Work component applications can access the ports they need (including the Adabas Directory Server port and those Entire Net-Work dynamically assigns during its own processing). For more information about Entire Net-Work ports, read Port Number Reference. For information about configuring Entire Net-Work components for Windows personal firewall, read Configuring Product Components for Windows Personal Firewall, in the Entire Net-Work Server LUW Installation and Administration Guide.
