Making topics multicast

To make individual topics, or groups of topics, capable of being multicast you need to make changes to the topic hierarchy:
  1. Switch to the Broker Administration perspective.
  2. In the Domains view, expand the appropriate broker domain.
  3. Double-click on the Topics item to open the Topics Hierarchy editor.
  4. In the Topics Hierarchy editor, right-click the topic, or group of topics, that you want to make capable of being multicast, and select properties.
  5. In the left panel of the properties window, select Multicast.
  6. Choose the Multicast Enabled required.

    For the topic root, the choice is either Enabled or Disabled. The default is Disabled.

    For a child topic root, the choice can be Inherit, Enabled, or Disabled. The default is Inherit.

  7. Check the Automatic Multicast Address box, or type in the name of the MC Group Address.
  8. Choose the Quality of Service required. The choice is between Reliable or Unreliable. The default is Reliable.
  9. Optional: Select the Encrypted check box.
  10. Click OK.
