Release 10.1A: OpenEdge Development:
Progress Dynamics Administration

Keeping SmartDataObjects alive on the server

When running over a stateless AppServer, dynamic SmartDataObjects (SDOs) must be retrieved, constructed, and initialized on the server for every client request. In terms of performance, this process can sometimes be more expensive than fetching the data itself. To eliminate this overhead, you can configure SDOs to remain in server-side memory (keep alive) for reuse by subsequent client requests.

Note: In the current release, you cannot keep alive static SDOs running in static containers.
