Starting, Stopping and Modifying Queues

Starting/Stopping a Queue

Queue objects cannot be executed. You start and stop them.

When stopping a Queue, Workflows and Schedules change their state to STOP - Queue processing has been stopped. This does not affect any other active tasks, though. Any other objects that are activated in a stopped Queue get the Waiting for queue slot status. If you start the Queue again, the tasks that were in a "waiting" state can also start.

You start and stop Queues from the Administration and from the Process Monitoring perspectives:

Administration perspective
1. Select Queues in the Administration navigation pane.
2. Select one or more Queues and right-click to select Stop/Start Queue.
Process Monitoring perspective
1. In the Tasks pane, select Queue from the Grouped by dropdown list.
  
  The pane displays all Queues available for the Client.
2. Right-click a Queue and select Start/Stop Queue.

An icon helps you identify the status of the Queue object, a green triangle indicating an active queue and a red square an inactive one.

Modifying a Queue

After you have defined a Queue object, you can still edit its definition:

In the Administration perspective

Right-click a Queue to select Open or Open in New Window. The Queue opens in edit mode.

In the Process Monitoring perspective

From the Process Monitoring you can only edit the number of maximum concurrent tasks and the priority.

On the Tasks navigation pane on the left hand side select Queues, right-click one and select Modify.

Note: In Client 0 it is not possible to modify Queue parameters.
