Message Header
The Message Header page is accessible only from its corresponding message's page. It contains message
identification and routing information, as well as application-specific properties that provide information
about how the message should be processed or interpreted. NOTE: Message headers apply primarily to JMS messages.
The Message Header page contains the following information:
Name of Defining Message: The name of the message for which this header is defined.
NOTE: The message's name is automatically provided when the header is created.
Message ID: The identifier assigned by the application or process that creates or sends the message.
Message Destination: An indication of whether the message will be sent to a topic (delivered to multiple subscribers) or a queue (a staging area containing messages that are waiting to be read).
Delivery Mode: An indication of whether the message is persistent (the message will be recovered in the event of a message broker failure) or non-persistent (the message will be discarded in the event of a failure).
Priority: A single digit indicating the priority level assigned to the message.
Destination Name: The name of the topic or queue to which the message is being sent.
Time to Live: The measurement of how long the message is to live. The producer's default time to live is unlimited; the message never expires.
List of Application-Specific Properties: The names, descriptions, and permissible values of properties (fields) that provide information about how the message should be processed or interpreted.
NOTE: Properties are created or edited on a separate Application-Specific Properties page which is accessible only from the message header's page.
Application-Specific Properties
The Application-Specific Properties page is used to create or edit a property, i.e., a message header field that provides
information about how the message should be processed or interpreted. NOTE: The page is accessible only from its corresponding message header's page. A message header can have more than one property.
The Application-Specific Property page contains the following information:
- Name (required): The name used to identify the property.
- Description: A short passage that describes the property.
- Permissible Values: A description of the property's set of allowable instances (values), together with their definitions.
- Filter Criteria: The message header attribute(s) which will be used if routing and filtering requirement will be requested by the service subscribers.
