When you add a SCAAsyncResponse node to a message flow, configure it to construct a pair of message flows that start a component asynchronously.
Ensure that the message set contains an IBM® Integration Bus SCA definition with an extension of .outsca with which to configure the node.
There are two methods of putting an instance of the node into a message flow: You can either drag an instance of the node from the node palette, or drag an IBM Integration Bus SCA definition with an extension of .outsca from a message set, onto the message flow editor canvas. Dragging an IBM Integration Bus SCA definition with an extension of .outsca onto the canvas creates a pair of SCAAsyncRequest and SCAAsyncResponse nodes.
If you have dragged an instance of the node from the palette onto the canvas, you must then start to configure it by dragging an IBM Integration Bus SCA definition with an extension of .outsca onto the node. The values for many of the node properties are provided in the IBM Integration Bus SCA definition. If you have dragged an IBM Integration Bus SCA definition onto the canvas and created a pair of SCAAsyncRequest and SCAAsyncResponse nodes, many of the values for the node properties have already been supplied from the IBM Integration Bus SCA definition.
The properties of the node are displayed in the Properties view. All mandatory properties for which you must enter a value (properties that do not have a default value defined) are marked with an asterisk.
On the Response Message Parsing tab, the properties are set automatically from the Integration Bus SCA Definition file.
