Configuration Options     Related Tasks     Related Topics

Destinations can override some of the settings (such as priority) that a message producer includes with its messages. Use this page to configure such overrides for this topic.

You configure topics explicitly or by configuring a JMS template to define and manage multiple topics with similar attribute settings.
