Building Distributed

Using the Progress AppServer
Application Broker
The Application Broker:
- Registers with the controlling NameServer the Application Services that the AppServer provides. For more information on Application Services, see Overview of the Progress AppServer."
- Manages connections between clients and a pool of Application Server processes that it starts.
- Maintains the status of each Application Server process in its pool and scales the number of processes according to changing demand.
- When configured for stateless operating mode, dispatches remote requests to Application Server processes.
One Application Broker provides connection management for a single AppServer instance. However, you can configure multiple AppServer instances, possibly using different operating modes and accessing different resources, for a single AppServer installation. For information on broker configuration options, see the "Configuring AppServer Components" section.
