How to Use Host Integrator

The diagram below shows a Host Integrator installation in which users can access legacy application data using a Web browser. Although each component is represented as running on separate machines, more than one component can run on the same machine. It is important to note, however, that although it is possible to run all Host Integrator components on the same machine, this is usually only done for development and testing.

Accessing Legacy Host Data from a Web Application

Although Web applications are the most common way to access Host Integrator server, you can also create client/server applications. You can have an installation in which users access host data by running client applications that communicate directly with Host Integrator Server over WCP.

In this type of deployment, the client application on the computer must contain all the logic for accessing the host data, which includes connecting to the Host Integrator Server, requesting the model, providing the user interface between the model and the client, managing the session, and trapping and resolving errors.

Sessions

In this documentation, the term "session" is a general term that describes a single session between a client or Web application and the host. The term "host session" refers to the connection between a Host Integrator Server and the host; host sessions run over Telnet.
