setPrefetchCount procedure

Sets the number of messages a SonicMQ client can retrieve in a single operation from a queue containing multiple messages.

Syntax

PROCEDURE setPrefetchCount. DEFINE INPUT PARAMETER count AS INTEGER.

Applies to

Session objects

Notes

The default is 3. For example, a count of 3 means that the Sonic client retrieves up to three message from a queue.
When the OpenEdge Adapter for SonicMQ sends a message to a queue that is full or to a topic whose queue is full, an error is raised.
If this procedure is called after the beginSession procedure is called, an error is raised.
