Uniform distributed queues - configure general parameters

Before you begin

After you create a uniform distributed queue, you can modify and define general property values, such as selecting a destination key for sorting messages as they arrive on the members of the distributed queue.

To configure general values for the members of a uniform distributed queue:

  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 queue resource that you want to configure:
  3. On the Configuration: General page:
    1. In Name, a name for the uniform distributed queue.

      Once you create a uniform distributed queue, 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 queue within the JNDI namespace.

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

    3. Optionally, in Template, select a template to define configuration values.
    4. In Load Balancing Policy, specify a policy (Round Robin or Random) for how messages are distributed to the members of this distributed queue.
    5. In Forward Delay, specify the amount of time, in seconds, that a queue member with messages, but with no consumers, will wait before forwarding its messages to other queue members that do have consumers.
    6. In Reset Delivery Count On Forward, species whether or not the delivery count is reset during message forwarding between distributed queue members.
    7. Optionally, in Destination Keys, specify keys for sorting messages.
    8. In Default Targeting Enabled, specify if this destination uses default targeting. Oracle recommends that destinations, regardless of their type, use Advanced Targeting to ensure that they are directly targeted to a JMS server or SAF agent.

    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).
