Queue Step
Queues provide access to applications or middleware that produce and consume data in the form of messages. Queues encapsulate the information necessary to establish a connection with the messaging system. Queue components can access data and services provided by message queuing systems. This includes the ability to read and write multiple messages to and from a queue and transactional support. You can read more than one message using a loop. Queue components can provide access to common message queuing systems such as FTP Queue, AWS S3 Queue, File Folder Queue, Email Queue, JMS Queue, Oracle AQ, IBM MQ, and MSMQ. They can also be used to provide a queuing interface to a nonmessage-based system, like a file system. Typical queuing systems perform a destructive read. In other words, once a message is read, it is removed from the queue.
For each type of queue component, you create a corresponding Queue step. The Queue step allows you to select a specific instance of a component and to specify the Action for the component to execute.
To add a Queue step:
1. Drag and drop a 
Queue step from the Palette to the canvas.
Queue step from the Palette to the canvas.2. Double-click the step on the canvas to open the Step Properties tab.
3. Type a unique name for the step.
4. Create an instance of this component in one of the following ways:
• By clicking the Select Queue dropdown and then selecting Add a New Queue.
• From the Configuration tab > Message Components section.
5. Specify the step properties.

Queue Step Properties.
Name | Description |
|---|---|
Name | Unique name for the step. |
Description | (Optional) Description of the step. |
Enabled | Select this option to enable the step for execution. If it is not enabled, then the step on the canvas is greyed-out. This option is useful when troubleshooting a process, especially when there are numerous steps in the process. |
Error Handling | Select either of the following: • Stop Process - (Default) All the steps after the current step are skipped or the entire process is stopped (depending on how you have the error logging options set) if this step stops due to an error. • Ignore Error - The remaining steps in this process are executed even if this step stops due to an error. This is useful when you want to write a Decision step that can test for the error state of a previous step. |
Select Queue | Select a Queue component instance. These instances are displayed when you add message components in the Configuration tab. For more information, see Adding Message Components in Configuring Processes. |
Action | Select the action for the queue instance. |
Message | Enter (or select) the name of a message. Note: This parameter must be the name of a message, not a message variable. If a message was created from a wizard, the message name is available in the dropdown list. If a message was created after the top-level process executed, the message name must be manually entered. For information about adding message component instances, see Adding Message Component Instances or SQL Sessions. |
Property | Properties for the selected action. Specify values for the properties. |
Note: The Actions, Parameters, and Properties are specific to the component type. For information about this, based on the component instance selected in the Select Queue drop-down list, click the component type in the Queue Step Components section below.
