When you have created a message
flow, add nodes to define its function.
About this task
To add a node to a message flow:
Procedure
- Open the message flow with which you want to work.
- Open the Palette.
- Hold the mouse pointer over the palette bar while it is in collapsed
mode. The palette bar expands. When you move the mouse pointer away
from the palette bar, it collapses again.
- Click the Show Palette icon at the top
of the palette bar. The palette bar expands and it remains expanded
when the mouse is moved away from the palette bar. To collapse the
palette bar again, click the Hide Palette icon
at the top of the palette bar while it is in expanded mode.
- Click Selection above the palette
of nodes.
- Decide which node you want to add: a
built-in node or a user-defined node.
You can select any
of the nodes that are displayed in the node palette, but you can add
only one node at a time.
Nodes are grouped
in categories according to the function that they provide. To see
descriptions of the nodes in the palette, either hold the mouse pointer
over a node in the palette, or switch to the Details view by following
the instructions in Changing the palette layout.
- Drag the node from the node palette onto
the canvas.
When you add a node to the canvas, the editor
automatically assigns a name to the node, but the name is highlighted
and you can change it by entering a name of your choice. If you rename
the node, the name that you choose must be unique in the message flow.
If you do not change the default name at this time, you can change
it later, see Renaming a message flow node. The default name
is set to the type of node for the first instance. For example, if
you add an MQInput node
to the canvas, it is given the name MQInput; if you add a second MQInput node, the default name
is MQInput1; the third is MQInput2, and so on.
- Repeat steps 4 and 5 to add further nodes.
- You can also add nodes from other flows into this flow:
- Open the other message flow.
- Select the node or nodes that you want to copy from
the editor or outline views, and press Ctrl+C or click .
- Return to the flow with which you are currently working.
- Press Ctrl+V or click .
This
action copies the node or nodes into your current flow. The node names
and properties are preserved in the new copy.
Results
When you have added the nodes that
you want in this message flow, you can connect them to specify the
flow of control through the message flow, and you can configure their
properties.
What to do next
Now you can configure the nodes, see Configuring a message flow node.
