Administration Console Online Help

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:
   • Navigate to JMS Resources in System Modules
   • Navigate to JMS resources in an application module
3. On the Configuration: General page, click the Advanced button.
   1. In Unit-of-Order, specify whether you want the system to create a system-generated unit- of-order name that is statistically unique for this distributed topic. Any message landing on this distributed topic that does not already belong to a unit-of-order is automatically assigned with this default unit-of-order name.
   2. If you are using the Unit-of-Order feature, in Unit-of-Order Routing, specify how the distributed topic members are selected as the destination for a message. If set to Hash, the producer computes the topic member. If set to Path Service, the configured Path Service determines the topic member.
   3. In Attach Sender, specify whether messages landing on this distributed destination should attach the credential of the sending user by selecting either: Supports, which sets the JMSXUserID property with the security principal of the sending user if requested; Never, which never sets the JMSXUserID property with the security principal of the sending user; Always, which always sets the JMSXUserID property with the security principal of the sending user.
   4. In SAF Export Policy, specify whether a user can send messages to this distributed topic using the Store-and-Forward service.
   5. In Messaging Performance Preference, specify how you want the distributed topic to perform in regards to emphasizing message latency or message throughput.

   For more information about these fields, see Configuration Options.

4. Save your changes:
   • Save Changes to JMS Resources in System Modules
   • Save changes to JMS resources in an application module
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).
