Using Gates to Control the Flow
A gate is a special kind of order queue that you use to control your provisioning flow. Place a gate module after a parser so it can buffer orders while the rest of your flow is being initialized or reconfigured.
When a gate is first created, it is closed and no orders will flow downstream from it. The gate can be opened to allow orders to flow downstream. And then it can be closed again to stop the flow of orders again.
When the gate is closed, all orders received are queued in the gate. When the gate is opened, all queued orders - and then all other orders received - are sent to the "good" port, port 1.
You can open and close the gate from the command-line using the provadmin script.
For more information about using gates in your flow, refer to the component documentation.
