Components

These components are contained in the system:

  • The host server is the primary working component. It holds all the program files and configuration information required to perform message brokering functions.
  • The client is the user interface to the host server.
  • The security server is an optional service that provides advanced security features.

The system must have at least one host server and one client. If there is only one client, then it must run on the same machine as the host server.

A typical system is composed of one host server and several clients. One client runs on the same machine as the host server and the others run on connected machines.

The system may or may not have a security server. If there is a security server, then it must be connected to the host server, but it usually runs on a separate machine. A client is never directly connected to the security server.
