Shared-memory configurations

Shared memory is an area in system memory that multiple users can access concurrently. OpenEdge keeps resources shared by all database users in shared memory and lets multiple servers access those resources efficiently. Optionally, additional asynchronous I/O processes can off load I/O operations from each server, further improving resource utilization and performance.
Local clients running multi-user OpenEdge can access database resources directly, rather than through a database server. This eliminates client/server message exchange and task-switching overhead. Database requests do not have to be queued until a server can process them. Local direct-access clients are known as self-service clients.
To run OpenEdge over a network, you need information regarding network-related system files, network configuration, and the startup parameters required to start remote clients. For more information about the network files and configuration, see Client/server and OpenEdge AppServer in the network environment and Preparing to run OpenEdge on a TCP/IP network. For information about starting remote clients, see Starting and Running OpenEdge
