Message queue: Listen adaptor

The message queue listen adaptor allows a graph to listen to messages arriving in a message queue and process them. The listen adaptor continuously polls the queue for new messages. In the adaptor, you can specify the poll interval.

Creating the adaptor

To create the message queue listen adaptor on any graph, complete the following steps:

Note

To create a message queue listen adaptor, it’s best practice, but not necessary, to create a database connection.

  1. Click Add in the upper-right of the graph window which will display the Listener configuration dialog box.
  2. In the Adaptor Connection (Environment) list, either click the connection you want to use or edit it directly by clicking the pencil icon next to the connection name.
  3. Specify the Listen Interval in seconds.
  4. Choose the target location for the output from the queue.
  5. Click Save.
