Starting a Component
In order to start a component, the following conditions must be met:
The component's configuration must be valid.
All defined Relationships for the component must be connected to another component or auto-terminated.
The component must be stopped.
The component must be enabled.
The component must have no active tasks. For more information about active tasks, see the "Anatomy of …" sections under Monitoring of DataFlow (Anatomy of a Processor, Anatomy of a Process Group, Anatomy of a Remote Process Group).
Components can be started by selecting all of the components to start and then clicking
the Start button ( 
) in the Operate Palette or by right-clicking a single component and
choosing Start from the context menu.
If starting a Process Group, all components within that Process Group (including child Process Groups) will be started, with the exception of those components that are invalid or disabled.
Once started, the status indicator of a Processor will change to a Play symbol ( 
).
