⟩ How should I use sorted queues?
Destination keys are used to define the sort order for a specific destination. Destination keys can be message header or property fields. For a list of valid message header and property fields, refer to the Programming WebLogic JMS.
Queues can be sorted in ascending or descending order based on the destination key. A destination is considered to be first-in-first-out if a destination key is defined as ascending for the JMSMessageID message header field, and last-in-first-out if defined as descending. The key defined for the JMSMessageID header field, if specified, must be the last key defined in the list of keys.
You can define multiple destination keys to sort a destination.
