OpenEdge Getting Started: Installation and Configuration - Product ...

Appendix F: Configuration Models
Note that OpenEdge often runs in local area networks (LANs) that have no network file
servers. On these LANs, application workstations can only access locally stored
procedures, and database server machines can only access locally stored databases.
However, the application workstations and database server machines can
communicate with each other as remote processes.
Single-process database server machine
A single-process database server machine is a node that runs only one server process
for each database, providing access to that database for self-service clients only.
Multi-process database server machine
A multi-process database server machine is a node that runs multiple server processes
for each database, providing multiple data paths to the database. Each server queues
and runs requests for one or more clients. A separate broker process starts a new
server for each additional client (or set of clients, in specified increments) that access
the database. For more information on server machine configurations, see the
“Shared-memory configurations” section on page 506.
You can dedicate all the resources of a database server machine to run database
servers. However, depending on your application and operating system, you can also
run local clients and remote clients for other database server machines.
Simple client/server configurations
Figure 13 shows a simple client/server configuration, where the client and server
components both run on a single system.
