Creating node connections with the mouse

Use the mouse to connect one node to another.

Before you begin

Read the concept topic about connections.

About this task


  1. Switch to the Integration Development perspective.
  2. Open the message flow with which you want to work.
  3. Click the terminal from which the connection is to be made; that is, the terminal from which the message is propagated from the current node.

    For example, you can click the Failure, Out, or Catch terminal of the MQInput node. Hold the mouse pointer over each terminal to see the name of the terminal. You do not need to keep the mouse button pressed.

    Alternatively, click Connection on the palette, then click the node from which the connection is to be made. The Terminal Selection dialog box opens for you to choose the terminal from which to make a connection. Click OK. If a node has five or more input or output terminals (for example, if you have added dynamic terminals), they are displayed in a group. The following example shows a node with more than four output nodes. The image shows a node with an output terminal group. To select a particular output terminal, click the grouped output terminal to open the Terminal Selection dialog box.

  4. Click the input terminal of the next node in the message flow (to which the message passes for further processing).
    The connection is made when you click a valid input terminal. The connection appears as a black line between the two terminals.


To view metadata information for a node, subflow, or connection:
  1. Switch to the Integration Development perspective.
  2. Open a message flow.
  3. In the Message Flow editor, hold the mouse pointer over a node, a subflow, or a node connection in the open message flow by placing the mouse over the element.
A custom tooltip is displayed below the element.
  • To turn the pop-up window into a scrollable window, press F2.
  • To hide the pop-up window, either press Esc or move the mouse away from the node.

What to do next
