Using the Progress AppServer


AppServer Components

An AppServer relies on the following components to manage client connections and execute remote procedure requests:

An AppServer instance is one Application Broker and the pool of Application Server processes that it manages. An AppServer instance has a specified configuration and makes a well-defined set of 4GL procedures available for execution by client applications.

An AppServer installation is the Progress AppServer product environment installed on a particular machine. Depending on your licensing and resources, you can configure and run multiple AppServer instances using a single AppServer installation.

For more information on AppServer components and how they interact, see the "Run-time Components and Operation" section. For more information on how client applications connect to an AppServer instance, see the "Connection Process" section. The following sections provide more basic information on how clients and AppServers and the types of configurations that AppServers support.
