Weighted distributed topics - configure general parameters

After you create a weighted distributed topic, you can modify and define general property values, such as changing the load balancing policy or specifying a SAF export policy.

To configure general values for the members of a weighted distributed topic:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the Administration Console, navigate to the uniform distributed topic resource that you want to configure:
  3. On the Configuration: General page:
    1. In Name, a name for the weighted distributed topic.

      Once you create a weighted distributed topic, you cannot rename it. Instead, you must delete it and create another one that uses the new name.

    2. In JNDI Name, enter the JNDI name used to look up the distributed topic within the JNDI namespace. Applications use the JNDI Name to look up the distributed topic.

      Note: A distributed topic that does not have a JNDI Name can be referenced by passing the Name of the distributed topic to javax.jms.TopicSession.createTopic().

    3. In Load Balancing Policy, specify a policy (Round Robin or Random) for how messages are distributed to the members of this distributed topic.
    4. In Unit-of-Order Routing, specify the method (Hash or PathService) for how a producer determines the destination member.
    5. In SAF Export Policy, specify whether a user can send messages to this distributed topic using the Store-and-Forward service.

    For more information about these fields, see Configuration Options.

  4. Save your changes:
  5. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
