Overview of Message Queue Polling

Message Queue Polling Concepts

Message queue polling is a SAS feature that enables you to monitor a message queue and start SAS programs to fulfill requests in the queue. You can configure message queue polling for WebSphere MQ or for JMS, which includes any message-oriented middleware vendor that includes a JMS provider.
Message queue polling is performed by the message queue polling server. The message queue polling server is a specialized SAS server that monitors a queue and performs SAS processing on the messages in the queue. Message queue polling servers are managed by the Object Spawner. The spawner creates polling server sessions as needed, and balances the workload between the server sessions.
Note: JMS does not support monitoring the depth of a queue. The object spawner always maintains the same number of polling server sessions.

Overview of Configuring Message Queue Polling

To configure message queue polling, perform the following steps:
  1. Define a Queue Manager for WebSphere MQ, or Define a Queue Manager for JMS.
  2. Define a Message Queue Polling Server
  3. For polling servers that interact with JMS destinations, Configure Your Java Environment for the Object Spawner and the JMS Access Method.
  4. Add the Polling Server to the Object Spawner Definition
  5. Configure Your Programs for Message Queue Polling
