Define the Simple Workflow Example Decision Bindings
You bind a workflow's elements together in the Schema tab of the workflow editor. Decision bindings define
how decision elements compare the input parameters received to the decision statement, and generate output
parameters according to whether the input parameters match the decision statement.
Prerequisites
You must have created the Start VM and Send Email workflow, defined its parameters, laid out its schema,
and linked the schema elements together.
Procedure
1 Click the VM Powered On? decision element.
2 Click the Decision tab in the schema element properties pane at the bottom of the Schema tab.
3 Click the Not set (NULL) button and select vm as the decision element's input parameter from the list of
proposed parameters.
4 Select the state equals statement from the list of decision statements proposed in the drop-down menu.
A Not set button appears in the value text box, which presents you with a limited choice of possible values.
5 Select poweredOn.
6 Click Save at the bottom of the workflow editor's Schema tab.
You have defined the true or false statement against which the decision element will compare the value of the
input parameter it receives.
What to do next
You must define the bindings for the other elements in the workflow.
Bind the Simple Workflow Example Action Elements
You bind a workflow's elements together in the Schema tab of the workflow editor. Bindings define how the
action elements process input parameters and generate output parameters.
Prerequisites
You must have created the Start VM and Send Email workflow, defined its parameters, laid out its schema,
and linked the schema elements together.
Procedure
1 Click the startVM action element.
2 Set the following general information in the Info tab.
Interaction
No external interaction
Color
None
Business status
Check the check box and add the text Sending start VM.
Description
Leave the text Start / Resume a VM. Return the start task
