AMQP Event Source Properties

For each AMQP event source that you create, you set the following properties to dequeue messages or subscribe to the service. Each event source defined is available to use in a process that handles the messages.
Event Source Property
Description
Enable Load Balancing
Required. Determines whether the connection must be deployed on all the Secure Agents in a group or on the selected Secure Agent for load balancing. You must enable this option only if the Process Server uses a Secure Agent Cluster configuration.
Default is No.
After you publish a connection and run a process, if you toggle the load balancing option, you might see duplicate messages. To avoid this issue, Informatica recommends that you create a new connection if you want to change the load balancing option.
Custom Message ID
Optional. Specify the custom message ID to override the default JMS message ID. Ensure that the message header contains the custom message ID.
Destination Type
Required. Indicates the AMQP destination type.
Select one the following values:
  • - queue
  • - topic
Destination
Required. The name of the queue or topic that you have defined in AMQP. For example, if the destination type is a topic in ActiveMQ, you would specify the Destination value in the following format:
topic://<topic-name>
Payload Format
Required. Specifies the type of message payload format that you expect on the destination.
Select one of the following values:
  • - XML
  • - JSON
  • - Text
  • - Binary
Objectlist Field Name
Optional. If the payload format is JSON, the queue or topic might accept a JSON message that contains an array of objects. If it does, enter the value to be used as the field name of the object list in the AMQP message body.
Dead Letter Queue Name
Optional. The name of a queue that you have defined in AMQP where you can route messages that encounter a failure during processing.
The question mark (?) character is prohibited in this field.
Other Attributes
Optional. The other attributes that you want to use for the event source.
Specify the attributes in key-value pairs. Separate multiple attributes with an ampersand character (&).
For example, enter the following phrase to specify the number of concurrent consumers and the maximum number of concurrent consumers:
concurrentConsumers=1&maxConcurrentConsumers=2
For more information about the attributes that you can specify, see the Apache Camel JMS documentation.
