Uniform distributed topics - specify a subdeployment

If you used the Advanced Targeting mechanism when creating a uniform distributed topic (UDT), you can change the subdeployment assigned to the UDT. A subdeployment is a mechanism by which JMS resources are grouped and targeted to specific server resources within a system module's targeting scope. Uniform distributed topics and queues depend on the JMS servers they are targeted to for the management of persistent messages, durable subscribers, and message paging. To reconfigure a subdeployment's targets, use the parent system module's subdeployment management page.

For example, you can use subdeployments to link specific server and JMS resources with the UDT members. For example, if a JMS system module is targeted to three WebLogic Server instances: wlserver1, wlserver2, and wlserver3, each with a configured JMS server, and you want to target a UDT and a connection factory to each server instance, you can group the UDT and a connection factory in a subdeployment (e.g., servergroup), to ensure that these resources are always linked to the same server instances.

To associate a UDT with a subdeployment:

  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 UDT resource that you want to configure:
  3. Click the Subdeployment tab.
  4. In the Subdeployments drop-down, select a subdeployment to associate with the UDT.

    To manage existing subdeployments in a JMS system module, use the module's Subdeployment management page. For more information, see Configure subdeployments in JMS system modules.

  5. Save your changes:
  6. 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).
